Definitions

  • the invention relates to a clamping unit with clamping cylinder for clamping workpieces, which can be fixed on a receiving plate.
  • the invention relates to a clamping unit for clamping relatively small and very small workpieces, which are clamped on machine tables, pallets, towers and the like and which are fed to a plurality of machining operations and which are brought into different positions depending on the processing cycle.
  • clamping units with a special shape.
  • clamping cylinder such as block cylinder introduced in box shape of different dimensions, which are attached with lag screws.
  • the serving for receiving the workpieces tables and plates are to shorten the working hours very tightly fitted. Accordingly, the clamping units must be designed so that they can be safely and firmly applied to the tables and / or pallets with respect to their attachment. It must also be ensured that the chips produced during processing are eliminated and do not exert any disruptive influence.
  • the pressure oil inflow to actuate the Tensioning piston is usually made in the known designs without pipe fittings.
  • the clamping operations require different heights to initiate the clamping forces, so that an adaptation to the given clamping heights must be done, which is done by means of different, different high intermediate pieces, which are made specifically for each case. Many different intermediate pieces increase the storage. Alternatively, several superimposed intermediate pieces are used, wherein the strength of the clamping unit is not always given.
  • the invention is based on the problem to provide a clamping unit which can be fixed in a simple manner on a receiving plate or the like even with a very tight assembly with workpieces.
  • the clamping unit according to the invention is characterized in that the clamping unit is associated with a pin on its underside, which is insertable into a receiving bore of the receiving plate and in this by means of a pressure bolt, which is guided in a tilted in the receiving plate side bore, fixable is.
  • the clamping unit thus needs to be used only by means of its pin in the receiving bore of the receiving plate. Subsequently, the pressure pin is used. It moves obliquely to the pin, whereby it is clamped in the mounting hole.
  • the clamping unit can thus be fixed in a particularly simple manner.
  • the pressure pin engages in a recess of the pin.
  • the pin is not only frictionally held, but even form-fitting.
  • the pressure pin is a pressure screw with an external thread and the side bore provided with a complementary internal thread.
  • the pressure screw is directed obliquely downwards relative to the pin and exerts a corresponding force on the pin, so that the pin is pulled into the receiving bore. This results in a Niederyak bin on the pin, so that the clamping unit is pressed onto the mounting plates and held securely.
  • the pressure screw can engage from any arbitrary side on the pin of the clamping unit.
  • a preferred position is on a back of the Clamping unit, ie on the side facing away from the clamping side with a pressure piece of the clamping cylinder.
  • particularly preferred is a below the pressure piece of the clamping cylinder, so the tension side, arranged pressure screw.
  • the pressure screw thus exerts a tilting moment on the clamping unit, which counteracts a tilting moment caused by the clamping of a workpiece.
  • the holding forces exerted by the pressure screw on the pin due to the clamping forces are enhanced.
  • the clamping unit is formed on its underside in the form of a disc, which is however still arranged above the pin.
  • the receiving plate is provided with a complementary recess into which the disc can be inserted.
  • the penetration depth into the recess is made variable, for example by a height-adjustable bottom of the recess, different clamping heights can be achieved in a simple manner. It is also expedient to provide a receiving plate with a plurality of receiving holes, which are all provided with different depth recesses or no recesses. This also makes it possible to achieve different clamping heights. Furthermore, it can be provided for height adjustment of the intermediate pieces, which in turn are provided with a receiving bore for the clamping unit. For each receiving bore on a receiving plate, whether provided with a recess or not, so different clamping heights can be achieved with only a single spacer. The intermediate piece should in turn be fixed with one or more connecting screws on the receiving plate and in turn has a side hole for the pressure screw.
  • two opposite sides of the clamping unit are parallel to the clamping cylinder, each provided with a flattening according to a development of the invention.
  • the housing of the clamping unit may be provided with vertically guided from above holes, which can serve to receive lag screws for securing the clamping unit to the receiving plate. It when one of these lag screws is arranged on the tension side below the clamping cylinder is particularly advantageous. This lag screw then counteracts by the clamping forces on the clamping unit applied tilting moments.
  • the clamping unit is formed spherically in the form of a sphere. Due to the spherical shape, a particularly good chip flow is achieved during exciting machining of a workpiece. In addition, given the spherical design smallest possible dimensions of the clamping unit without affecting their strength and a good tool access for the multi-side machining.
  • a section through the clamping unit 1 is shown.
  • a recess 3 is introduced, in which a clamping cylinder 2, for example, a screw-in cylinder is inserted.
  • This clamping cylinder 2 is provided with a screw-in thread or an equivalent closure, for example a bayonet closure, and the recess 3 with the mating thread or a counterpart, so that the clamping cylinder 2 in the recess 3 can be inserted and fixed directly without further assistance ,
  • a clamping piston 24 is guided in and extendable.
  • the clamping unit 1 is crowned, in particular as part of a ball 4, formed.
  • the spherical shape has the advantage that the chips produced during machining of the workpieces are removed more easily.
  • the lower part of the crowned clamping unit 1 is provided with a downwardly directed pin 5, which forms a unit with the body of the clamping unit 1.
  • This pin 5 serves to accommodate the clamping unit 1 on tables, pallets, towers and the like - hereinafter referred to as the receiving plate 6.
  • a disc 14 is arranged, which serves as an abutment when setting the clamping unit 1 on the receiving plate 6.
  • the receiving plate 6 is provided with receiving holes 7 which are arranged at a certain distance from each other. In this receiving bore 7 of the pin 5 is inserted, the dimensions are coordinated, so that hardly a game is given.
  • each receiving bore 7 with a, introduced at a predetermined angle side bore 8.
  • This side bore 8 is guided by the receiving plate 6 so that it engages in the receiving bore 7.
  • the side bore 8 is provided with an internal thread into which a pressure screw 9 can be screwed.
  • This pressure screw 9 is determined in its length so that it protrudes into the receiving bore 7.
  • the pin 5 is in the area in which the Pressure screw 9 protrudes on the side bore 8 in the receiving bore 7, provided with a recess 10 which corresponds to the diameter of the pressure screw 9.
  • the pin 5 is inserted into the receiving bore 7, in such a way that the recess 10 is located exactly opposite the side bore 8. Now, if the pressure screw 9 is screwed into the side hole 8, it penetrates into the recess 10 and at the same time exerts a pressure on the pin 5, which forces it down into the receiving bore 7. For a rotationally secure and fixed arrangement of the clamping unit 1 is given on the receiving plate 6, which withstands all clamping and machining forces.
  • Each clamping unit 1 requires to actuate the clamping piston 24 a pressure medium supply. Thus, connections to the pressure medium supply system are required. These connections should be as free as possible from screw connections in the area of the clamping surfaces.
  • the clamping cylinder 2 shown in Fig. 1 is double-acting and accordingly requires two connections to the pressure medium system. In the body of the clamping unit 1 holes 11 are inserted, which come after fixing the clamping unit 1 on the receiving plate 6 on the inserted in the receiving plate 6 pressure fluid connections 12 to lie. By means of known recordings, a leak-free connection between receiving plate 6 and clamping unit 1 can thus be produced.
  • Fig. 2 the clamping unit is shown in phantom in phantom.
  • the clamping unit 1 can be reduced by flattening 13 in its cross section. These flats 13 are attached to the opposite sides, which extend approximately parallel to the clamping cylinder 2. As a result, the strength of the clamping unit 1 is not impaired.
  • Such a flattening 13 is only possible if the fixing of the clamping unit 1 takes place on the receiving plate 6 outside of the flat area, as this requires the side hole 8.
  • the fixing of the inserted into the receiving plate 6 clamping unit 1 by means of a pressure screw 9 is particularly space-saving, when the pressure screw 9 is arranged on the back of the clamping unit, ie on the opposite side of the clamping piston 24 of the clamping cylinder 2.
  • the clamping unit 1 is placed on top of the receiving plate 6.
  • Fig. 3 it is shown that the clamping unit 1 can also be inserted into the receiving plate 6.
  • the lower part of the clamping unit 1 is circular in shape, in the form of a disc 14.
  • the receiving plate 6 accordingly receives a circular recess 15 into which the disc 14 can be inserted.
  • the recess 15 is variable in depth, so that can be produced at the onset of the disc 14 different heights.
  • one and the same clamping unit 1 can be supplied to the receiving plates 6 by implementing various tasks.
  • the clamping cylinder 2 can also be arranged extremely close to the receiving plate 6.
  • the height adjustment of the clamping unit 1 is also given by means of intermediate pieces 22. These spacers 22 are inserted between the receiving plate 6 and clamping unit 1. They are determined in their outer forms and are adapted by their thickness to the conditions. All determinations described so far are also applicable to the intermediate pieces.
  • FIG. 4 shows different mounting situations for a clamping unit 1 with the receiving plate 6, which in the present case both receiving holes 7 with recesses 15 (Fig. 4a and 4c), as well as receiving holes 7 without recess 15 (Fig. 4b and 4d), below Use of the intermediate pieces 22.
  • the clamping unit 1 as shown in Fig. 3, with its disc 14 inserted into a recess 15 of the receiving plate 6, so that there is a low clamping height H1 for the clamping piston 24.
  • Fig. 4b the clamping unit is inserted into a receiving bore 7 without recess 15, so that there is a higher clamping height H2.
  • Fig. 4c shows the clamping unit used in a receiving bore 7 with recess 15.
  • the intermediate piece 22 is still arranged under the disc 14, so that the clamping height H3 is greater than the clamping height H2 of FIG. 4b.
  • the maximum clamping height H4 results when the clamping unit, as shown in Fig. 4d, with the spacer 22 in a receiving bore 7 without recess 15 is used.
  • four different clamping heights H1 to H4 for the clamping piston 24 can be achieved with only one receiving plate 6 and only one intermediate piece 22.
  • the intermediate piece 22 is fastened to the receiving plate 6 in each case by at least one separate connecting screw 25.
  • such an intermediate piece 22 is shown, which is fastened by three own connecting screws 25 on the receiving plate 6.
  • the attachment of the clamping unit 1 can also be done by means of a connection between the bottom of the receiving plate 6 and the pin 5. This is shown in Fig. 5a.
  • the receiving plate 6 is below the receiving bore 7 with a extended blind bore 17 provided so that between the receiving bore 7 and blind bore 17, a web 18 remains. In this web 18, a bore 30 is introduced. Through this bore 30, the clamping unit 1 is fixed by means of a screw 19.
  • the pin 5 is accordingly introduced from below a threaded blind bore 31 with a corresponding internal thread. If the screw 19 is not used, the pin 5 can be provided at the lower end with a threaded projection 28, which in turn protrudes through the web 18 and is fixed from below by a nut, see Fig. 5b.
  • the pin 5 may be additionally provided with the recess 10, so that the same clamping unit 1 can be fixed either from below or from above. This reduces the number of embodiments and thus the storage.
  • the centering and attachment of the clamping unit 1 is additionally or alternatively to the pressure screw 9 by means of one or more, in the present case two vertically introduced by the housing of the clamping unit 1 from above, introduced into holes 20 in the housing lag screws 21 possible.
  • This can be seen in FIGS. 6, 7a and b.
  • a total of two holes 20 are introduced, in places where the strength is not impaired.
  • These holes 20 are aligned with two of the holes 26 in the intermediate piece 22 (Fig. 7).
  • the third bore 26 in the intermediate piece 22 is arranged on the tension side below the clamping cylinder 2 and thus additionally absorbs tilting moments acting on the clamping unit 1 by clamping.
  • the holes 20 and 26 are sized so that they coincide with the drilling intervals in the receiving plate 6.
  • connection between the clamping unit 1 and the receiving plate 6 can be produced, using the lag screw or plug pins or the like.
  • the clamping unit in this embodiment in the plan view of a circular cylinder (Fig. 6) is formed.
  • Fig. 9 shows a clamping unit 1 analogous to the clamping unit 1 according to FIG. 6 to 8.
  • Fig. 10 shows an embodiment of a clamping unit 1, which is associated with a single-acting piston 16, which is retrieved by the force of a spring 27, the clamping cylinder 2. Accordingly, the pressure medium connection is only necessary once, thus, here a pipe connection 23 can be used, which results in the leakproof connection by means of screwing.
  • the intermediate piece 22 is shown, which allows a separate attachment to the receiving plate 6.
  • at least one bore 26 is introduced, in each of which a connecting screw 25 is inserted into the receiving plate. 6 engages and is fixable there.
  • three holes 26 are each provided with a connecting screw 25, one of which should be arranged on the tension side under the clamping piston 24 again to avoid tilting moments.
  • FIG. 11 There are applications in which the piston position of the clamping cylinder 2 relative to the surface of the receiving plate 6 must be inclined. This is shown in FIG. 11.
  • the clamping unit 1 is provided with a recess 3, which occupies a certain angle. An inserted into this recess 3 clamping cylinder 2 will thus initiate its force under the predetermined angle in the workpiece to be machined in the application. This can be advantageously used to exert a low tensile force on the workpiece to be clamped.
  • the embodiment of the clamping unit 1 according to FIG. 12 essentially corresponds to the exemplary embodiment according to FIG. 11 with a clamping cylinder 2 inserted at an angle.
  • this exemplary embodiment differs from the exemplary embodiments described above in that the pressure screw 9 does not lie on the free end of the Clamping piston 24 opposite (back) side of the clamping unit 1 but below the free, the workpiece facing (front) side and thus under the pressure piece 32 of the clamping piston 24 is arranged.
