Definitions

  • the present invention relates to a support element for a screw clamp and a screw clamp, which can be better adapted to a wide variety of uses and fix a workpiece more reliably.
  • Screw clamps which are intended in particular for use on so-called clamping tables or welding tables and each have a vertical and cross strut.
  • the two struts are arranged at an angle of 90 ° to each other.
  • a threaded spindle is held at a free end of the cross strut, with which workpieces can be fixed on the welding table.
  • the disadvantage is that these known screw clamps are limited in terms of flexibility of use and adjustability. Furthermore, torques can act on the known screw clamps, which lead to the fact that a workpiece cannot be reliably fixed.
  • the DE 10 2008 045975 A1 describes a clamping device for storing and fixing a workpiece on a work table with a clamping column and with a clamping arm, on which a spindle head with a thread guide for guiding a pressure spindle is arranged, the clamping column and the clamping arm being operatively connected by means of a plug connection.
  • a screw clamp is also known, which is used on dressing or welding tables and serves to fix a workpiece on it.
  • the longitudinal axis of the first element runs through the center of the essentially circular or ring-shaped cross section.
  • the longitudinal axis of the receiving element runs through a center of the area into which the fastening means is inserted or inserted.
  • the longitudinal axis of the fastening means when it is arranged in the receiving element, is congruent with the longitudinal axis of the receiving element.
  • intersection of both longitudinal axes i.e. the first element and the receiving element need not be positioned within the two elements. Specifically and preferably, the intersection lies at least outside the first element, so that the intersection lies on an imaginary extension line of the longitudinal axis of the first element.
  • annular shape preferably refers to the fact that an inner section has no material and this inner section is essentially circular.
  • shape of the outer wall of the receiving element does not necessarily have to be circular.
  • the receiving element is preferably suitable for receiving the fastening means in that it has a thread into which the fastening means or an adapter can be screwed. But plug connections or frictional connections are also possible.
  • the longitudinal axis of the first element, the longitudinal axis of the receiving element and the axis of rotation of the receiving element preferably run along an imaginary three-dimensional Cartesian coordinate system if the two above-mentioned longitudinal axes are arranged at a 90 ° angle to one another.
  • the support element according to the invention thus allows it to be flexibly adjusted, in particular in cooperation with a welding table or other components, for example an angle element or a further support element.
  • the flexibility is achieved in particular in that the receiving element Holds fasteners rotatable or pivotable, so that in particular workpieces can be fixed, for example, which have curved surfaces.
  • the first element in particular when used in combination with welding tables and / or accessories therefor, can be inserted into a suitable receiving opening, so that in combination with the welding table and / or the accessories, fixing arrangements can be put together according to a particular application.
  • the carrier element according to the invention that the first element, the fulcrum / intersection and the longitudinal axis of the receiving element or of the fastening means are arranged in the same imaginary plane. This means that the generation of undesired torques can be reduced or reduced. These are generated in particular with known screw clamps, in which e.g. the longitudinal axis of a fastener is not in the same plane as the longitudinal and transverse struts of the known screw clamps.
  • the flexibility of use of the first carrier element is increased even further, since, when it is inserted or inserted into a counter-shaped receptacle, it can rotate about the longitudinal axis of the first element.
  • the first carrier element offers two axes of rotation, which enormously increase the degrees of freedom when adjusting or adapting to a workpiece or to an application.
  • the holder element can have at least two legs.
  • the two legs are arranged essentially L-shaped to each other.
  • the receiving element is arranged on an inner wall of one of the two legs so that it can rotate at least around the axis of rotation.
  • the other leg is connected to an outer wall on an end face of one of the two free ends of the first element.
  • the legs are preferably flat profiles, the height of which essentially corresponds to the diameter of the first element.
  • an advantageous weight reduction is made possible, so that the holder element is made very light and at the same time mechanically strong and rigid.
  • a shorter leg is particularly preferably provided, the outside of which is connected flat and firmly to the end face of the first element.
  • a welded or soldered connection is particularly suitable for this purpose if the individual elements are metallic, an adhesive connection, preferably in the case of plastic elements, and / or a screw connection.
  • a second, longer leg is preferably provided, which is arranged in an L-shape to the shorter leg, the longer leg preferably being arranged parallel to the longitudinal axis of the first element.
  • the parallel arrangement of the longer leg allows the receiving element to be precisely aligned with the first element.
  • the two legs can be connected directly to one another, also in one piece.
  • an intermediate section can also be provided, which e.g. forms a radius-shaped transition between the two legs.
  • the radius additionally increases the stiffness of the holder element.
  • the shorter leg can be rounded at one end so that the rounding essentially corresponds to an outer contour of the first element. This enables optimal weight savings and a compact, ergonomic design. Additionally or alternatively, the longer leg can be rounded at one end, so that the rounding essentially corresponds to an outer contour of the first element. This enables optimal weight savings and an ergonomic design.
  • outer wall of the legs is intended to refer to the holder element, so that the respective outer walls of the legs are those which are arranged on the convex side of the L-shape.
  • the inner walls of the legs are then correspondingly on the concave side.
  • the wall surfaces of the legs are preferably designed to be flat in order to allow the least complex shape possible.
  • the L-shaped holder element can preferably support the receiving element on one side.
  • This one-sided mounting for example in that the receiving element is arranged only on the longer leg and is rotatably fastened there, brings about another Material savings and thus weight reduction compared to double-sided storage.
  • the L-shape of the holder element ensures mechanical rigidity and shape retention of the holder element even with one-sided storage.
  • This arrangement and mounting of the receiving element is structurally advantageous since no complexly designed brackets have to be provided and at the same time it is made possible that the longitudinal axes of the receiving element and the first element intersect and the receiving element can rotate as freely as possible.
  • the receiving element can have a partially open or closed ring shape with a thread in the region of the inner wall.
  • the thread can be designed to receive a thread of the fastener.
  • a partially open ring shape is possible, for example, if part of the ring circumference is left out, e.g. on a width that corresponds to the diameter of a fastener.
  • the complete ring shape is preferred. This allows a fastener to be inserted or inserted from above or below. Due to the thread and the stable ring shape, the fastener can be held securely by the receiving element. The length in the longitudinal axis of the fastener, which is arranged laterally to the receiving element, can be changed or set due to the thread by means of a turning or screwing movement.
  • the receiving element can have at least one shaft arranged on an outer wall, which can be arranged in a hub of the leg of the holder element.
  • the arrangement can also be reversed, i.e. there is a shaft on the leg and a receptacle or hub on the receiving element.
  • the shaft-hub connection allows the formation of an axis of rotation about which the receiving element can rotate.
  • the connection can e.g. be secured by means of a screw or the like. Such a construction can be produced with little effort, but allows a very reliable and precise function.
  • a screw connection can also be provided, which Receiving element rotatably mounted on the holder element.
  • a planar surface can be provided on the outer wall of the receiving element, which is in flat contact with the inner wall of the longer leg of the holder element and is pulled by a screw connection to the inner wall.
  • the first carrier element can have a rotating device which can comprise the shaft and the hub for rotatably mounting the receiving element on the holder element and a contact section in which a section of an outer wall of the receiving element and a section of an inner wall of the holder element can be in contact with one another, if the receiving element is rotatably mounted on the holder element.
  • a rotating device which can comprise the shaft and the hub for rotatably mounting the receiving element on the holder element and a contact section in which a section of an outer wall of the receiving element and a section of an inner wall of the holder element can be in contact with one another, if the receiving element is rotatably mounted on the holder element.
  • the contact section is the section at which a section of the holder element or its leg and part of the receiving element touch at least slightly. This at least slight contact is the origin of a frictional force which can prevent the receiving element from being turned too easily or automatically if this should be necessary. Furthermore, the frictional contact can be adjusted by a closer contact of the two sections so that the rotation of the receiving element with a predetermined e.g. force that can be applied by hand. Of course, this is optional: there can also be no contact section.
  • the contact section can represent a sliding surface.
  • latching grooves and projections of the inner wall of the holder element and the outer wall of the receiving element can be in contact with one another on the contact section.
  • the locking grooves and projections can, for example, at least partially interlock, so that an operator must apply a predetermined torque in order to bring about a rotation.
  • the rotating device can also have an elastic element, for example a spring, which acts axially in the direction of the axis of rotation and pulls the depressions and projections towards one another. The operator can then trigger a rotation, for example, by pulling on the receiving element in the axial direction of the axis of rotation, ie counter to the spring force and at the same time it rotates around the axis of rotation. When the receiving element is released, the spring pulls the depressions and projections back together, so that a further rotation is blocked again or made more difficult.
  • a distance between an inner wall of the leg of the holder element, which can be arranged at the free end of the first element, and an outer wall of the receiving element can be at least as large or larger than / as the distance between the intersection of the longitudinal axis of the first element with the Longitudinal axis of the receiving element and a point on an outer edge of the receiving element.
  • the outer edge is an edge of the receiving element, which delimits an outer circumference of the receiving element and at the same time an axial length thereof.
  • a point on the outer edge should be as far from the inner wall of the opposite leg as the distance to the pivot point of the receiving element for the 360 ° rotatability of the receiving element without the fastening means. This distance can be determined by means of the length of the longer leg that holds the receiving element. Furthermore, the distance is most preferably chosen such that a fastening means can be pivoted at least 90 ° clockwise and counterclockwise from a vertical position. If the distance is chosen so that it is somewhat larger than the length of the fastener, a 360 ° rotation can also be achieved when the fastener is installed.
  • the radius of the outer wall of the receiving element can be the same size or larger than / as a radius of the first element.
  • the length of the receiving element can be at least as long as the diameter of the first element. This enables the carrier element to be as compact as possible.
  • the fastening means can be a threaded spindle or a quick release.
  • the fastening means can be arranged in a thread adapter, the internal thread of which can essentially match an external thread of the fastening means and the external thread of which can essentially match the thread of the receiving element. Threaded spindles have different thread diameters.
  • Adapter sleeves can be used to allow a flexible selection of threaded spindles, but also other components such as a quick release be provided which have an internal thread adapted to the threaded spindle and an external thread which matches the thread of the receiving element.
  • the adapter sleeves have the advantage that a very flexible use of different fastening means is made possible, which can be mounted on / in the receiving element with little (change) effort.
  • the two longitudinal axes of the two parts essentially coincide, i.e. they are congruent. This prevents the generation of undesired torques, since the first element, the pivot point of the receiving element and the longitudinal axis of the fastening element are in the same plane.
  • a screw clamp according to the invention can have a first support element according to the invention and a second support element.
  • the second carrier element can have a second element and a substantially circular cross section.
  • the second element can have two free ends.
  • a substantially circular element can be arranged on one of the two free ends of the second element.
  • the annular element can be suitable for movably supporting the first element of the first carrier element.
  • the movable mounting of the first element or of the first carrier element in relation to the second carrier element improves the adaptability of the screw clamp to a large number of purposes.
  • the longitudinal axes of the first and second elements are preferably arranged in the same plane.
  • the annular element can have a circular ring section which is designed to hold the first element rotatable about its longitudinal axis and displaceable along its longitudinal axis. Moving along the longitudinal axis enables many different clamping ranges to be set.
  • the rotatability enables, in particular in combination with the further rotatability of the receiving element, an optimal adaptation to, for example, the shape of a component to be fixed.
  • a predetermined clearance or transition fit can be provided between a diameter of the circular ring section and a diameter of the first element. Preference is given to fits that allow the first element to be moved and / or rotated in the circular ring section by hand. Other fits are of course also possible.
  • the second support element can hold the first support element such that the longitudinal axes of the first and second elements can lie in a common imaginary plane, and an intersection of the longitudinal axis of the first element with a longitudinal axis of the receiving element can be arranged in the same common imaginary plane.
  • first and second elements can each have essentially the cross section of a round tube and both elements can have essentially the same radius. This enables the two elements to be mechanically very resilient. Due to the same radius, a variable combination of different first and second elements can be made possible.
  • the length of the annular element can be at least as long as the diameter of the second element. This reduces the size of the screw clamp to a minimum.
  • the invention thus enables the carrier element and the screw clamp to be adapted very flexibly and, inter alia, even complex shaped workpieces can be securely fixed.
