Drawings
The invention is explained in more detail below with the aid of the figures. The invention is not limited to the embodiments shown in the drawings. The figures only schematically illustrate the subject matter of the invention. Wherein:
Fig. 1 shows an exploded view of a holding device;
fig. 2 shows a perspective view of the workstation.
Detailed Description
Fig. 1 shows an exploded view of a holding device 10 for holding a workpiece 1 to be processed. The holding device 10 is part of a workstation on which the work piece 1, in particular a housing part of a reduction gear, is processed. The holding device 10 is fastened to a column 12, which also belongs to the workstation.
The holding device 10 comprises a fastening unit 8 by means of which the holding device 10 is fastened to the upright 12. The upright 12 has a fastening slot 84 extending in the vertical direction Z. A nut, not shown here, is arranged inside the fastening groove 84 in a manner movable in the vertical direction Z. The fastening bolt 82 passes through the fastening unit 8 and is inserted into the nut. By tightening the fastening bolts 82, the fastening unit 8 can be locked on the upright in the vertical direction Z at a defined height.
The holding device 10 comprises a clamping unit for clamping the workpiece 1 to be processed. The clamping unit has an intermediate element 5 and a clamping element 2. The intermediate element 5 is arranged in the longitudinal direction X between the fastening unit 8 and the clamping element 2. The workpiece 1 to be machined is clamped between the intermediate element 5 and the clamping element 2.
The clamping unit has a main guide pin 6 and a sub guide pin 7. The guide pins 6, 7 are fastened to the intermediate element 5 and protrude from the intermediate element 5 in the longitudinal direction X. The guide pins 6, 7 are cylindrically configured. The guide pins 6, 7 are arranged offset from each other in the transverse direction Y.
The longitudinal direction X extends at right angles to the transverse direction Y. The longitudinal direction X extends at right angles to the vertical direction Z. The vertical direction Z extends at right angles to the transverse direction Y.
A main guide opening 86 and a sub guide opening 87 are introduced into the fastening unit 8. The guide openings 86, 87 have a circular cross section and are arranged offset from one another in the transverse direction Y. The guide openings 86, 87 extend parallel to each other in the longitudinal direction X.
The main guide pin 6 of the clamping unit protrudes into the main guide opening 86 of the fastening unit 8. The secondary guide pin 7 of the clamping unit protrudes into the secondary guide opening 87 of the fastening unit 8.
Two fixing screws 9 are arranged on the fastening unit 8. The fixing screws 9 extend parallel to each other and are screwed into the fastening unit 8 in the vertical direction Z. The main guide pin 6 can be fixed in the main guide opening 86 by means of the fixing screw 9.
By tightening the fixing screw 9, a locked state is established in which the main guide pin 6 is fixed in the main guide opening 86. The loosened state is established by unscrewing the fixing screw 9, in which the main guide pin 6 can move relative to the main guide opening 86.
A through opening 52 is introduced in the intermediate element 5. When the guide pins 6, 7 of the clamping unit protrude into the guide openings 86, 87 of the fastening unit 8, the through-openings 52 are aligned with the fastening bolts 82. Thus, even when the intermediate member 5 is fixed to the fastening unit 8, the fastening bolts 82 can be screwed through the through openings 52.
The clamping unit has a clamping screw 4. The clamping screw 4 passes through the clamping element 2 in the longitudinal direction X and is inserted into the clamping opening 54 of the intermediate element 5. A slot 24 is provided in the clamping element 2, which slot extends in the transverse direction Y, the clamping screw 4 passing through the slot 24. By tightening the clamping screw 4, the clamping element 2 can be clamped in the longitudinal direction X towards the intermediate element 5.
The clamping unit has a support element 3. The support element 3 protrudes from the intermediate element 5 in the longitudinal direction X on the side facing away from the guide pins 6, 7. The support element 3 is constructed in the form of a screw and is screwed into a hole in the intermediate element 5. By means of the rotation, the support element 3 is made movable in the longitudinal direction X with respect to the intermediate element 5.
The clamped workpiece 1 rests against the support element 3 and the clamping element 2. By rotating the support element 3 relative to the intermediate element 5, the holding device 10 can be fine-tuned to orient the workpiece to be machined in the longitudinal direction X.
The support element 3 has a soft coating on the side facing the clamping element 2. Damage, e.g. scratches, to the clamped workpiece 1 is prevented by the described coating in contact with the clamped workpiece 1.
The clamping unit has a support pin 57. The support pin 57 protrudes from the intermediate element 5 in the longitudinal direction X on the side facing away from the guide pins 6, 7. The support pin 57 is constructed in the form of a screw and is screwed into a hole of the sub guide pin 7. By means of the rotation, the support pin 57 is made movable in the longitudinal direction X with respect to the intermediate element 5.
When the workpiece 1 is clamped, the clamping element 2 rests on the support pin 57. By rotating the support pin 57 relative to the secondary guide pin 7, the clamping element 2 can be oriented relative to the intermediate element. The clamping screw 4 is arranged in the transverse direction Y between the support element 3 and the support pin 57.
Fig. 2 shows a perspective view of the workstation. The workstation is located in a manufacturing plant for producing the decelerator. The housing part is manufactured in a manufacturing plant and is further processed at a workstation. The work station shown here holds a work piece 1. The workpiece 1 is here a housing part of a reduction gear. For example, on a workstation, a hole for threading a shaft is introduced into the workpiece 1.
The workstation comprises two uprights 12 and a base 22. Two uprights 12 are fastened to the base 22 and extend from the base 22 in a vertical direction Z. The two uprights 12 are arranged offset from each other in the transverse direction Y.
The workstation comprises three fixed holding elements 20 on which the work piece 1 is held. Two of the three fixing elements 20 are fastened in the fastening groove 84 of one of the uprights 12 offset from one another in the vertical direction Z. One of the three retaining elements 20 is fastened in a fastening slot 84 of the other upright 12. The workstation further comprises a holding device 10 as shown in fig. 1. The holding device 10 is fastened in a fastening slot 84 of one of the uprights 12 in a staggered manner in relation to one of the holding elements 20 in the vertical direction Z.
In order to hold the workpiece 1 to be processed on the work station, the workpiece 1 is first fastened to three fixed holding elements 20. By means of the three fixed holding elements 20, the workpiece 1 is fixed in a static manner at three points of the workstation.
Subsequently, the workpiece 1 is fastened to the holding apparatus 10. In this case, the holding device 10 is first locked to the upright 12 at a desired height in the vertical direction Z. For this purpose, the fastening bolts 82 inserted into nuts in the fastening grooves 84 of the column 12 are tightened.
The holding device 10 is arranged in such a way that the workpiece 1 is located between the intermediate element 5 and the clamping element 2. The clamping screw 4 is then tightened, thereby clamping the clamping element 2 in the longitudinal direction X towards the intermediate element 5. Thereby clamping the workpiece 1 to be machined between the intermediate element 5 and the clamping element 2.
The guide pins 6, 7 which protrude into the guide openings 86, 87 of the fastening unit 8 are automatically adjusted in this case in the longitudinal direction X, so that the workpiece 1 is held free of play and stress. Subsequently, the fixing screw 9 is tightened, thereby fixing the main guide pin 6 in the main guide opening 86. Thereby, the workpiece 1 to be processed is additionally held at the fourth point.
The workpiece 1 to be machined is thus held, with the aid of the holding element 20 and the holding device 10, at four points, on the upright 12 of the workstation without play and without stress.
