Definitions

  • the invention relates to a guide rail for a linear bearing, with a plurality of through openings for the reception of fastening elements arranged one behind the other at intervals in the longitudinal direction of the rail for receiving fastening elements, with a longitudinal groove open to the upper side of the rail and extending over the entire length of the guide rail, and with one in the longitudinal groove used and fastened, the passage openings closing off the cover band, the longitudinal groove being delimited by a lower groove wall and two oblique side walls rising up from it and in cross section of the guide rail the lower groove wall in each case forms an obtuse angle with one side wall, and two on the side walls Wall grooves extending from the longitudinal groove are arranged in the guide rail in the longitudinal direction thereof, in which the cover band is held on its longitudinal sides.
  • Guide rails are used, for example, on machine tools and have to be replaced as wear parts from time to time. Therefore, they are often attached to the machine frame with screws. In most applications, the countersunk holes of the guide rail for the fastening screws have to be closed for various reasons. This process is complex and expensive. To close the radially widened end sections of the bores for the screw heads, it is known in use a stopper or a cap for each end section, as shown, for example, by the documents DE 30 46 590 A1 and DE 93 16 349 U1. The use of caps has the disadvantage of insufficient mechanical holding forces. In addition, a complex assembly is required because each cap must be used individually.
  • a guide rail of the type mentioned at the outset is known from EP 0 311 895 A1.
  • the longitudinal groove on the top of the rail only needs to be so wide that the cover band used securely closes the through-openings of the guide rail, which are arranged one behind the other in the longitudinal direction of the rail.
  • the masking tape is glued to the bottom of the longitudinal groove between two adjacent through openings on the guide rail. This creates a stable arrangement of the masking tape, but it cannot be easily detached from the guide rail. If a detachment has been carried out with great effort, both the masking tape and the guide rail must be freed of the adhesive, for example ground off.
  • a cover band is used to close the holes for the screws, which, when pressed into the longitudinal groove of the guide rail, bulges over its entire width towards the guide rail. Due to its restoring spring force, the cover strip claws into the side surfaces of the longitudinal groove, so that it is held there in the groove along two contact lines. The space of the passage openings is closed to the outside along these lines of contact. As a result of its bulging, this masking tape does not have a flat sealing surface on its outer top. In addition, there is a risk with this version that the masking tape is pressed onto the surface in which the counterbores for the fastening screws are located.
  • the document DE 38 12 505 A1 shows a guide rail of the type mentioned, in which a plate made of plastic is used as the cover tape, which has a flat trapezoidal cross section. Rib engagement sections are formed on two long sides of the plate, while correspondingly recessed sections are formed in a linear channel of the guide rail that receives the plate. Therefore, the plate can be inserted into the channel from one end of the guide rail. The plate is then attached to the guide rail only in that the rib sections engage in the recessed sections. Pressing the plate into the channel from the upper long side of the guide rail is therefore not possible.
  • the invention has for its object to provide a tight cover for the passage openings of a guide rail with a good sealing effect, the geometry of the masking tape does not have to meet any special requirements and the masking tape is easy to assemble and disassemble.
  • the assembly or disassembly should also be possible if one or more carriages are mounted on the guide rail. It should therefore be possible to replace the masking tape when the machine is fully assembled. If possible, the tape should be easy to assemble without tools.
  • the cover strip is rectangular in cross section and is supported within the wall grooves with its lower longitudinal edges and upper longitudinal edges on the guide rail.
  • the cover strip can be pushed into the wall grooves from an end face of the guide rail, and can also be pressed into the longitudinal groove from above and enter the wall grooves.
  • the wall grooves can be ground into the rail surface.
  • the wall grooves can be pushed in or pushed in the cover tape.
  • the cover tape lies with a slight pretension with a lower longitudinal edge on an inclined groove wall, while it can be located with the respective upper longitudinal edge approx. 0.1 to 0.5 mm below the cutting line of two inclined walls within the longitudinal groove.
  • it is mounted on the guide rail from above by pressing it into the longitudinal groove and the wall grooves, or the front of the masking tape is pushed into the grooves of the guide rail.
  • the contour of the surface of such a guide rail is shown in the area of the masking tape in a wiper-friendly manner.
  • Figure 1 shows an end portion of a first guide rail in a perspective view
  • Figure 2 shows a detail of the end region of a second guide rail according to section line II-II of Figure 1 in an enlarged view;
  • FIG. 3 shows a cross section corresponding to the encirclement IM of FIG. 2 through the second guide rail and the
  • FIG. 4 shows a cross section corresponding to FIG. 3 through the first guide rail.
  • a masking tape 1 which is made of a resilient tape material, for example a steel sheet can be used in a longitudinal groove 2 of a guide rail 3.
  • the longitudinal groove 2 starts from the upper side 4 of the rail and is delimited by a lower groove wall 5 and two inclined side walls 6.
  • a plurality of vertical through openings 7 arranged one behind the other at intervals in the longitudinal direction of the guide rail 3 are closed. These openings are designed as stepped bores for receiving fastening screws.
  • the guide rail 3 also has two longitudinal wall grooves 8, which start from the longitudinal groove 2.
  • Each wall groove 8 is located on an inclined side wall 6.
  • Both wall grooves 8 are arranged at the same height of the guide rail 3.
  • the cover strip 1 is rectangular in cross section and has a lower longitudinal edge 9 and an upper longitudinal edge 10 on each of its two long sides. With these edges, it is inserted into the adjacent wall groove 8 and held there.
  • Two parallel cutting lines 11 of the guide rail 3 protrude slightly above the outer surface of the cover strip 1, the upper edges 10 of the cover strip 1 being able to be located within the wall grooves 8, for example 0.1 to 0.5 mm below the cutting lines 11.
  • cover strip 1 If the cover strip 1 is pressed into the longitudinal groove 2 from above, it must deform slightly resiliently in order to be able to overcome the two cutting lines 11 and to get into the wall grooves 8. However, it is also possible to slide the cover strip 1 in the longitudinal direction into the wall grooves 8 from an end face of the guide rail 3.
  • the contour at the cutting line 11 allows the guide rail material to be flanged, which can serve to fix a non-tight masking tape.
  • the flanging takes place in 0.01 to max. 0.2 mm range.
  • the sharp edge at the cutting line is broken in this case.
  • the masking tape 1 can not by the pressure of a scraper on the Place the groove wall 5 and the through openings 7 cannot be reproduced in the masking tape 1, so that negative sealing effects are avoided.
  • the dimensioning of the longitudinal groove 2 can be kept so small that there is no significant impairment of the rigidity.
  • the guide rail 3 according to FIGS. 1 and 4 is basically also designed.
  • the wall grooves 12 are designed such that the masking tape 1 is supported not only via its lower longitudinal edges 9 and its upper longitudinal edges 10, but also at border lines 13 on the guide rail 3, which separate the oblique side walls 6 from the wall grooves 12.
