Although the fixture can process the top surface and end surface of workpiece sliding block, when the through hole needs to be processed at the connecting part of the two sides of sliding block and horizontal edge, the top pressure strip blocks the machining position of machine tool cutter on sliding block, if the connecting piece and top pressure strip are disassembled, the top pressure strip is reinstalled above the sliding block staggered with the through hole, so that the processing time of subsequent through hole is prolonged, the overall processing efficiency of sliding block is low, and the top pressure strip above the sliding block more or less blocks machine tool cutter, affecting the processing accuracy of through hole.

[0004] Therefore, the above fixture is difficult to meet the processing needs and accuracy requirements of through hole at the connecting part of the two sides of sliding block and edge, and there are problems of low work efficiency and difficult to guarantee processing accuracy. UTILITY MODEL CONTENTS

[0005] In order to solve the above technical problems, the utility model provides a kind of tooling fixture for vertical machining center machining sliding block, and the surface machining and hole machining of sliding block are completed by positioning assembly and tooling bottom plate.

[0006] In order to achieve the above purpose, the utility model is realized by the following technical scheme:

[0007] A kind of tooling fixture for vertical machining center machining sliding block, it includes:

[0008] The tooling bottom plate is installed on the worktable of the machining center and is used for assisting the machining center to process the arrayed and combined sliders.

[0009] The positioning assembly is arranged on the tooling bottom plate and is detachably connected with the tooling bottom plate, and is used for defining the machining position of the sliders through abutting, embedding and pressing.

[0010] Compared with the prior art, the tooling bottom plate has the following advantages:

[0011] The positioning assembly limits the sliders on the tooling bottom plate in the embedding, abutting and pressing modes, so that the machine tool cutter head can not only perform surface machining on the top surface and the end surface of the sliders, but also can perform through hole machining on the two side parts of the sliders.

[0012] Further preferably, the positioning assembly comprises:

[0013] The OK clamp is embedded in the tooling bottom plate and is located between the sliders of the adjacent two rows, the two side walls of the OK clamp abut against each sliders, and the OK clamp is detachably connected with the tooling bottom plate.

[0014] The cylindrical pin is arranged on the tooling bottom plate and is located outside the sliders and abuts against the side wall of the sliders, and is used for assisting the OK clamp to define the machining position of the sliders by extending into the tooling bottom plate.

[0015] The pressing plate is arranged on the OK clamp and is located between the sliders of the adjacent two rows, and is detachably connected with the tooling bottom plate, and is used for assisting the cylindrical pin to define the machining position of the sliders of the adjacent two rows and two rows.

[0016] By using the above technical scheme, the specific position of the sliders is defined on the tooling bottom plate from the horizontal direction and the vertical direction by the OK clamp and the cylindrical pin, and the pressing plate is further connected with the tooling bottom plate to press the sliders from the vertical direction, so as to further define the position of the sliders, avoid any shielding above the sliders, facilitate the machine tool cutter head to perform hole machining on the sliders, and exclude interference problems to ensure the machining accuracy of the through holes.

[0017] Further preferably, the tooling bottom plate is respectively provided with:

[0018] The positioning groove is arranged on the tooling bottom plate and is located between the sliders of the adjacent two rows, and the OK clamp is embedded in the positioning groove and cooperates with the positioning groove.

[0019] The grooves are a plurality of grooves arranged on the tooling bottom plate and located between the adjacent positioning grooves and penetrating through the tooling bottom plate.

[0020] The mounting holes are through holes, located on both sides of the positioning groove, and are used to mount the tooling base plate onto the worktable of the machining center using bolts.

[0021] The pressure plate holes are through holes, located on the outside of the slider and between adjacent OK clamps. Cylindrical pins extend into and mate with the pressure plate holes.

[0022] By employing the above technical solution, the positioning groove and the OK clamp are coordinated to limit the position of the OK clamp on the tooling base plate. Combined with the restraint of the pressure plate and cylindrical pin, the stability of the OK clamp on the tooling base plate is improved, enabling the clamping and releasing of the slider. The groove prevents damage to the tooling base plate when the cutting head is machining holes. The mounting holes facilitate the assembly and disassembly of the tooling base plate from the machine tool table. The pressure plate holes simultaneously limit the vertical position of the OK clamp and the slider, further constraining the slider.

[0023] More preferably, the width of the groove is greater than the diameter of the through hole on the slider.

[0026] The clamp body is set in the positioning groove and is connected to the positioning groove by bolts. Its two sides, which protrude from the tooling base plate, abut against the side walls of the adjacent sliders.

[0027] The stop block is set on the clamp body and fixed on the side wall perpendicular to the slider direction. Its bottom surface abuts against the edge of the positioning groove, and its side wall is on the same plane as the side wall of the clamp body.

[0028] By adopting the above technical solution, the stop block not only limits the depth of the clamp body in the positioning groove in the vertical direction by abutting against the positioning groove, but also assists in taking out or putting in the clamp body, making it convenient to disassemble and assemble the OK clamp.

[0029] Further optimization involves the pressure plate being either an "I" shape or a "King" shape.

[0030] Using the above technical solution, a single "I" shape can limit two rows and two columns of sliders at one time, and a single "King" shape can limit three rows and two columns of sliders at one time, which provides convenience for machine tools to process sliders efficiently.

[0031] Further optimization involves a pressure plate bolt, the end of which passes through the middle of the pressure plate and connects to the tooling base plate.

[0032] By adopting the above technical solution, the purpose of simultaneously limiting the OK clamp and the slider in the vertical direction can be achieved.

[0033] Further optimized, the pressure plate includes:

[0034] plate body, in any one of "work" type or "king" type, located between the two adjacent rows of sliders, with the recessed part in the middle connected with the pressing plate bolt.

[0036] The above technical scheme is adopted to limit the position of the slider on the tooling bottom plate in the arrangement mode of at least two rows and two columns or three rows and two columns, so as to achieve the purpose of efficiently processing the through holes on multiple sliders.

[0037] Further optimization is that the height of the stop block is less than the height of the clamp body, and the width of the stop block is less than the width of the clamp body.

DETAILED DESCRIPTION

[0049] The accompanying drawings, which are incorporated herein and form part of the specification, illustrate embodiments of the present application and, together with the description, further serve to explain the principles of the application and to enable a person skilled in the relevant art(s) to make and use the application. Figures 1-9 The utility model will be further described in detail.

[0050] A tooling fixture for machining sliding blocks 6 of a vertical machining center, as shown in the drawings, comprises: Figure 1

[0051] A tooling base plate 1 is installed on the worktable of the machining center and is used to assist the machining center in machining the arrayed and combined sliding blocks 6, which are a plurality of sliding blocks 6 combined in rows and columns.

[0052] A positioning assembly is arranged on the tooling base plate 1 and detachably connected with the tooling base plate, and is used to define the machining position of the sliding blocks 6 through abutment, embedding and pressure bonding.

[0053] The positioning assembly defines the sliding blocks 6 on the tooling base plate 1 in the manner of embedding, abutment and pressure bonding, so that the machine tool cutter head can not only perform surface machining on the top surface and end surface of the sliding blocks 6, but also perform machining of the through holes 61 at the two side parts of the sliding blocks 6. After the surface machining is completed, the machining of the holes is directly performed, which not only greatly shortens the machining time of the subsequent through holes 61 and improves the machining efficiency, but also directly avoids the shielding of the machine tool cutter head and improves the machining precision of the through holes 61.

[0054] Specifically, as shown in the drawings, Figure 1 , Figure 2 and Figure 9 , the positioning assembly in the embodiment comprises:

[0055] An OK clamp 2 is embedded in the tooling base plate 1 and located between the adjacent two columns of sliding blocks 6, the two side walls of which abut against each sliding block 6, and the OK clamp 2 is detachably connected with the tooling base plate 1, and the tooling base plate 1 is used to define the position of the OK clamp 2.

[0056] A cylindrical pin 3 is arranged on the tooling base plate 1 and located outside the sliding blocks 6 and abuts against the side wall of the sliding blocks 6, and is used to assist the OK clamp 2 in defining the machining position of the sliding blocks 6 by extending into the tooling base plate 1.

[0057] A pressing plate 4 is arranged on the OK clamp 2 and located between the adjacent two columns of sliding blocks 6, and is detachably connected with the tooling base plate 1 and is used to assist the cylindrical pin 3 in defining the machining position of the adjacent two columns and two rows of sliding blocks 6.

[0058] The specific position of the sliding blocks 6 is defined on the tooling base plate 1 by the OK clamp 2 and the cylindrical pin 3 from the horizontal direction and the vertical direction, and the pressing plate 4 and the tooling base plate 1 are further connected to press the sliding blocks 6 from the vertical direction, which plays a further defining role, avoids any shielding above the sliding blocks 6, facilitates the machine tool cutter head to perform hole machining on the sliding blocks 6, and eliminates interference problems to ensure the machining precision of the through holes 61. ​

[0059] Specifically, as shown in Figure 2 , Figure 3 and Figure 4 , the tooling base plate 1 in the embodiment is respectively provided with:

[0060] a positioning groove 11, which is provided on the tooling base plate 1 and located between the adjacent two rows of sliding blocks 6, and the OK clamp 2 is embedded in the positioning groove 11 and cooperates with the positioning groove 11.

[0061] a plurality of grooves 12, which are provided on the tooling base plate 1 and located between the adjacent positioning grooves 11 and penetrate the tooling base plate 1.

[0062] a mounting hole 13, which is a through hole 61 and provided on both sides of the positioning groove 11, and used for mounting the tooling base plate 1 on the workbench of the machining center through bolts.

[0063] a pressing plate 4 hole 14, which is a through hole 61 and respectively located between the adjacent OK clamps 2 and outside the sliding blocks 6. The cylindrical pin 3 extends into the pressing plate 4 hole 14 and cooperates with the pressing plate 4 hole 14.

[0064] Through the cooperation of the positioning groove 11 and the OK clamp 2, the position of the OK clamp 2 in the plane of the tooling base plate 1 is limited, and in cooperation with the limitation of the pressing plate 4 and the cylindrical pin 3, the stability of the OK clamp 2 on the tooling base plate 1 is improved, so that the clamping and loosening of the sliding block 6 are realized. The groove 12 avoids damaging the tooling base plate 1 when the tool bit processes the hole. The mounting hole 13 facilitates the disassembly and assembly of the tooling base plate 1 and the machine tool workbench, and through the pressing plate 4 hole 14, the positions of the OK clamp 2 and the sliding block 6 in the vertical direction are simultaneously limited, which further plays a role in limiting the sliding block 6.

[0065] Specifically, as shown in Figure 2 , Figure 3 and Figure 4 , the width of the groove 12 in the embodiment is greater than the diameter of the through hole 61 on the sliding block 6, which plays a role in completely avoiding the instantaneous damage of the tooling base plate 1 by the machine tool tool bit drilling through the through hole 61.

[0066] Specifically, as shown in Figure 1 and Figure 8 , the OK clamp 2 in the embodiment comprises:

[0067] a clamp body 21, which is arranged in the positioning groove 11 and connected with the positioning groove 11 through bolts, and the two side walls of the clamp body 21 protruding from the tooling base plate 1 respectively abut against the side walls of the adjacent sliding blocks 6.

[0068] a stop block 22, which is arranged on the clamp body 21 and fixed on the side wall perpendicular to the direction of the sliding block 6, and the bottom surface of the stop block 22 abuts against the edge of the positioning groove 11, and the side wall of the stop block 22 is coplanar with the side wall of the clamp body 21.

[0069] The stop block 22, by abutting against the positioning groove 11, not only limits the depth of the clamp body 21 in the positioning groove 11 in the vertical direction, but also assists in taking out or putting in the clamp body 21, making it convenient to disassemble and assemble the OK clamp 2.

[0070] Specifically, such as Figure 5 , Figure 6 as well as Figure 7 As shown, in this embodiment, the pressure plate 4 is at least one of the "I" shape and the "King" shape. A single "I" shape can limit two rows and two columns of sliders 6 at one time, and a single "King" shape can limit three rows and two columns of sliders 6 at one time, which provides convenience for the machine tool to efficiently process the sliders 6.

[0071] Further optimization involves a pressure plate bolt 5, the end of which passes through the middle part of the pressure plate 4 and connects to the tooling base plate 1.

[0072] By adopting the above technical solution, the purpose of simultaneously limiting the OK clamp 2 and the slider 6 in the vertical direction can be achieved.

[0073] Specifically, such as Figure 6 and Figure 7 As shown, in this embodiment, the pressure plate 4 includes:

[0074] Plate 41, which is either "I" or "King" shaped, is located between two adjacent rows of sliders 6, and its central recessed part is connected to the pressure plate bolt 5.

[0075] The protrusion 42 is set on the bottom surface of the plate 41, located on the two protruding parts of the plate 41. The bottom surface is fixedly connected to the plate 41, and the surface is in contact with the slider 6.

[0076] The position of the slider 6 on the tooling base plate 1 is limited in the arrangement pattern of at least two rows and two columns or three rows and two columns, so as to achieve the purpose of efficiently processing the through holes 61 on multiple sliders 6.

[0077] Specifically, such as Figure 8 As shown, in this embodiment, the height of the stop 22 is less than the height of the clamp body 21, and its width is less than the width of the clamp body 21. While occupying less space, it facilitates the assembly and disassembly of the OK clamp 2.

[0078] Please combine Figures 1-8 The clamping process in this embodiment is described as follows:

[0079] The tooling base plate 1 is installed on the worktable of the vertical machining center through the connection of holes and bolts, and is fixed by locking. The slider 6 is installed on both sides of the positioning groove 11 through the cylindrical pin 3. Then, the OK clamp 2 is installed into the positioning groove 11. The slider 6 is clamped by the force multiplication of the V-shaped wedge in the OK clamp, which cooperates with the positioning of the cylindrical pin 3. The slider 6 is further clamped by the pressure plate 4 and the pressure plate bolt 5, which makes the clamping and positioning of this tooling fixture more secure and reliable.

[0080] Therefore, the utility model can satisfy the processing requirement and precision requirement of the through hole 61 on the connecting part of the two sides and the edge of the sliding block 6, improve the working efficiency and the processing precision 2.

[0081] The embodiment is only an explanation of the utility model, and does not limit the utility model, and a person skilled in the art can make a modification without creative contribution according to the need after reading the specification, and the modification is protected by the patent law as long as in the protection scope of the utility model.
