Definitions

the invention relates to a swivel milling machine with the in the preamble of claim 1 specified features.
swivel milling machines on the market of this generic type Type is the milling device in a storage facility on the machine stand kept a pivoting of the milling spindle with the Milling tool in a swivel range of +/- 45 ° backwards or forwards enables.
the milling tool is in a table opening of the machine table arranged, the milling depth of the tool relative to the workpiece by shifting the on the machine table arranged milling stop in the depth direction.
This milling depth infeed via the milling stop has the disadvantage that with Every change in the milling depth changes the lateral position of the workpiece. This means that the workpiece must be transported through the milling machine Feed device, which is usually attached to a type of gallows and accesses the workpiece from above, in its lateral position be adjusted according to the adjustment of the milling stop. This is annoying and time-consuming with frequent changes in the milling depth.
the milling tool is provided with a degree of stroke freedom along the spindle axis.
the spindle When the spindle is swiveled out of the zero position, it has a lifting movement along the spindle axis, however, there is also a change in the milling depth Episode. This in turn means that to compensate for this change in depth the milling stop and the feed device accordingly are to be adjusted.
the invention is based on the object, a swivel milling machine to improve so that it is more rational and time-saving with high universality can be used for a wide variety of milling tasks.
the machine can now basically carry out the milling depth feed directly an adjustment of the milling tool itself and not by the milling stop be made. This means that if the Milling depth infeed the feed device at a constant lateral position can remain and does not have to be adjusted. This brings you considerable rationalization effect when working with the invention Swivel milling machine with itself.
the above construction also brings in the area of the machine table a constructive simplification since the milling stops are not must be more adjustable in the depth direction.
the invention provides a preferred embodiment before part of the machine table through an insert slide form, which partially forms the table opening for the milling tool.
This Insert slide can be moved in the depth direction and with the storage facility for the milling spindle coupled such that a depth shift the milling spindle in a synchronous depth adjustment of the insert slide is feasible. This means that the edge of the table opening with the usual "Air" can reach the milling tool.
the insert slide follows this adjustment movement, so that the gap between the milling tool and the edge of the table opening preserved.
the insert slide can be made with a larger diameter cutter in its position relative to the milling spindle, i.e. regardless of the Bearing device for the milling spindle adjustable in the horizontal depth direction be as a preferred embodiment of the invention further provides. So that the insert slide can be moved so that the Edge of the table opening again up to the usual gap Milling tool reaches.
the swivel milling machine has one as a whole with 1 designated machine stand with several, not in more detail shown pillars and struts.
a machine table 2 is arranged on it, the top of the work surface 3 of the milling machine forms.
the machine stand 1 is by a front cover 4, side covers 5 and a rear cover 6 enclosed.
This table opening 14 is in the machining area of the milling tool 13 not by the machine table 2 itself, but by an im Machine table arranged insert slide 15 formed in plan view approximately rectangular with a semicircular recess 16 in the the milling stop 7 facing side is formed.
the top of the Insert slide 15 is in one plane with the working surface 3 of the machine table arranged. Furthermore, the insert slide 15 is closer in later to be discussed in the depth direction T displaceable in the machine table 2 stored.
FIGS. 1 and 2 is in the rear area a vertically extending bearing column 17 is arranged on the machine stand, which clearly overlooks the machine table 2.
a vertically extending bearing column 17 is arranged on the machine stand, which clearly overlooks the machine table 2.
At the top is one fixed, projecting boom 18, the control panel 19 of the milling machine assembled.
About halfway between machine table 2 and Control panel 19 is on the bearing column 17 via a mounting block 20 Cantilever arm 21 attached, the usual at its free front end Feed device 22 for the milling workpieces 45, such as squared timbers, Wearing boards or the like.
This feed device 22 is as such known and points downward from its housing, rubber-elastic, resiliently mounted rollers 23, which have a corresponding Drive can be set in rotation.
the feed device 22 sets with these rollers 23 from above onto the respective workpiece 45 and pushes this in the feed direction V on the work surface 3 at the milling stop 7 along through the machine. By a certain inclination the feed device 22 becomes the milling workpiece 45 in a known manner pressed against the milling stop 7, so that a clean guide of the Workpiece 45 takes place.
the cantilever arm 21 is in the mounting block 20 in the longitudinal direction of the arm 21 slidably mounted, the boom length via a spindle drive 24 and thus the position of the feed device 22 transverse to the feed direction V is variable. Furthermore, the mounting block 20 is around the vertical pivotally attached to the bearing column 17.
the height adjustment of the feed device 22 for position adjustment the rollers 23 to the height of the respective workpiece 45 is motorized in that the bearing column 17 in a corresponding height guide 25th is vertically displaceably attached to the machine stand 1.
the drive takes place via a spindle drive 26, which is actuated by an electric motor 27 becomes.
Via a sensor 28 coupled to the spindle drive 26 Height position of the cantilever arm 21 and thus the feed device 22 be detected by the control device of the milling machine.
the fixation of the bearing column 17 in a certain height position on Machine stand is done by a clamping lever 29 from the rest Front of the machine, the clamping lever 29 via a corresponding Mechanics (dash-dotted lines in Fig. 1) on the bearing column 17 accesses. Also automatic clamping using a clamping cylinder is conceivable.
the workpiece height in the control program for a specific workpiece and the feed device 22 by the automatic spindle drive 26 be moved to an appropriate height.
the electric motor 27 can also a hydraulic or pneumatic cylinder for the drive the bearing column 17 are used in the vertical direction.
the multi-axis adjustable bearing device 30 for each Milling tool 13 carrying milling spindle 31 can be seen with reference to FIGS. 2 to 6 is to explain. Accordingly, the bearing device 30 is basically on in the depth direction T extending crossbeams 32 of the machine stand 1 in this direction slidably mounted.
a base support 33 is provided for this purpose, which is only indicated schematically in FIGS. 2 to 6. He can follow kind of a carriage or conveyor basket on the cross members 32 slidable be hung up.
the base support 33 can have lateral height guide cross members 34, on which an intermediate carrier 35 in the vertical direction is guided up and down. The vertical movement of this intermediate beam 35 is accomplished by means of two lateral spindle drives 36 which by an electric motor 37 on the base support 33 via a chain hoist 38 are driven.
a spindle carrier 39 is in turn horizontal and pivotable parallel to the feed direction V pivot axis 40 stored.
the pivoting movement is carried out on the intermediate carrier 35 flanged electric motor 41 accomplished, the over a chain hoist 42 accesses the bearing shaft 43 of the spindle carrier 39.
the spindle motor 44 is suspended in the spindle carrier 39, on its output shaft the milling spindle 31 is seated with the respective milling tool 13.
the milling spindle 31 is thus integrated directly into the spindle motor 44.
the pivot position of the spindle carrier 39 is otherwise by an angle encoder 46 detected on the bearing shaft 43.
the adjustment of the base support 33 of the bearing device 30 in the depth direction T along the crossbeams 32 is done manually via a on the machine stand 1 arranged manual spindle drive 47, the one on the front the machine can be operated via a rotary handle 48.
a rotary handle 48 In the handle 48 is integrated a counter that one of the depth position of the base support 33rd shows the corresponding value. The set milling depth can thus be read become.
base support 33 is also a coupling crossbar 49 already addressed slide valve 15 connected so that with a depth adjustment the base support 33 and the insert slide 15 within the machine table 2 in the depth direction T according to the depth adjustment of the milling tool 13 is adjusted with.
Adjustment spindle 50 arranged by a further rotary handle 41 on the Front of the insert slide 15 is actuated.
51 is the relative position of the insert slide 15 in the depth direction based on the bearing device 30 and thus the milling tool 13 adjustable. This is necessary if the dimensioning or Position of the milling tool 13 due to a tool change or when pivoting the milling spindle 31 changes. This is very obvious understandable by a comparison of FIGS. 3 to 6.
the insert slide has swivel angle S and in the manner of tool 13 there 15 a different depth position relative to the storage device 30 on.
