This utility model has the advantages of effectively assisting in fixing the processed parts, preventing the processed parts from shifting during processing, which is conducive to improving processing accuracy and reducing the damage to the electrode wire caused by part shift.

[0003] The existing technology has the following shortcomings: Although the above-mentioned wire EDM machine tool auxiliary fixture effectively solves the problem of material clamping in the existing technology, when clamping materials, due to the size, length, width, weight of the material and the unevenness of the object surface, the fixture may fall off while clamping these objects, resulting in material damage, great waste of material, and affecting the processing time. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary fixture for wire EDM machines that provides stable clamping, can hold workpieces of different shapes, and avoids damage to the workpiece surface.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The device includes a wire cutting machine body and a movable base mounted on the wire cutting machine body. A fixing plate is screwed onto the movable base, and the fixing plates are symmetrically arranged about the center of the movable base. Each fixing plate has a first sliding groove at the end furthest from the movable base. A moving rod is slidably connected inside the first sliding groove. A slide rail is fixed at the end of the moving rod furthest from the first sliding groove. A second sliding groove is provided inside the slide rail, and a moving block is slidably connected inside the second sliding groove. Two moving blocks are provided inside the second sliding groove. A U-shaped clamping block is fixed to the side of each moving block. An abutting elastic block is provided inside the U-shaped clamping block, and an auxiliary reinforcing member is provided on the side of the abutting elastic block.

[0007] Furthermore, a first lead screw is rotatably connected inside the first slide groove. One end of the first lead screw extends out along one end of the first slide groove, and a first rotating disk is fixed to the extended end. The first lead screw is threadedly connected to the moving rod.

[0008] By adopting the above technical solution, the reciprocating movement of the moving rod can be easily adjusted, and the clamping position can be adjusted according to different cutting directions.

[0009] Furthermore, a second lead screw is rotatably connected inside the second slide groove. One end of the second lead screw extends along one end of the second slide groove, and a second rotating disk is fixed to the extended end. A partition block is fixed in the middle of the second slide groove. The spiral direction of the threads on both sides of the partition block of the second lead screw is related, and the second lead screw is threadedly connected to the moving block.

[0010] By adopting the above technical solution, the movement of the moving blocks is facilitated, and the moving blocks on both sides are independently controlled, making it easy to clamp workpieces of different shapes.

[0011] Furthermore, the inside of the C-shaped clamping block is hollow, and an air guide pipe is connected to one side of the C-shaped clamping block. The air guide pipe is located away from the end that contacts the elastic block, and the C-shaped clamping block has several through holes facing the end that contacts the elastic block.

[0012] By adopting the above technical solution, the contact elastic block is made of TPU elastomer with high resilience. When clamping the workpiece, the contact elastic block can completely contact the workpiece surface. For workpieces of different shapes, the contact elastic block deforms and wraps around the workpiece when it contacts the workpiece surface, while providing protection for the workpiece surface. At the same time, the other side of the contact elastic block moves toward the workpiece end after air compression and contact, so that both sides contact the contact elastic block, making the workpiece clamping stable.

[0013] Furthermore, the abutting elastic block is slidably inserted into the inside of the C-shaped clamping block, and a plug-in plate is fixed to the end of the abutting elastic block facing the C-shaped clamping block.

[0014] By adopting the above technical solution, the plug-in plate slides inside the C-shaped clamping block, which facilitates the sliding of the elastic block.

[0015] In summary, the beneficial technical effects of this utility model are as follows:

[0016] 1. The first lead screw and the second lead screw are adopted to facilitate the reciprocating movement adjustment of the moving rod, which makes it easy to adjust the clamping position according to different cutting directions. At the same time, it is convenient to move the moving block. The moving blocks on both sides are independently controlled, which makes it easy to clamp workpieces of different shapes.

[0017] 2. An abutment elastic block is adopted, which is made of high-resilience TPU elastomer. When clamping the workpiece, the abutment elastic block can completely abut against the workpiece surface. For workpieces of different shapes, the abutment elastic block deforms and wraps around the workpiece when in contact with the workpiece surface. At the same time, it avoids the use of existing metal clamps, reduces rigid friction between the workpiece and the clamp, and provides protection for the workpiece surface. 3. An air guide tube is adopted. After the air is compressed and abuts against the workpiece, the other side of the abutment elastic block moves towards the workpiece end, so that both sides are in contact with the abutment elastic block, making the workpiece clamping stable.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3The present invention provides a technical solution comprising a wire cutting machine body 1 and a movable base 2 mounted on the wire cutting machine body 1. A fixing plate 3 is screwed onto the movable base 2. The fixing plates 3 are symmetrically arranged about the middle of the movable base 2. Each fixing plate 3 has a first sliding groove 4 at the end away from the movable base 2. A moving rod 5 is slidably connected inside the first sliding groove 4. A slide rail 6 is fixed at the end of the moving rod 5 away from the first sliding groove 4. A second sliding groove 7 is provided inside the slide rail 6. A moving block 8 is slidably connected inside the second sliding groove 7. Two moving blocks 8 are provided inside the second sliding groove 7. A U-shaped clamping block 9 is fixed to the side of each moving block 8. An anti-elastic block 10 is provided on the inner side of the U-shaped clamping block 9. An auxiliary reinforcing member is provided on the side of the anti-elastic block 10.

[0026] A first lead screw 11 is rotatably connected inside the first slide groove 4. One end of the first lead screw 11 extends along one end of the first slide groove 4, and a first rotating disk 12 is fixed to the extended end. The first lead screw 11 is threadedly connected to the moving rod 5.

[0027] A second lead screw 13 is rotatably connected inside the second slide groove 7. One end of the second lead screw 13 extends along one end of the second slide groove 7, and a second rotating disk 14 is fixed to the extended end. A partition block 15 is fixed in the middle of the second slide groove 7. The thread direction of the second lead screw 13 on both sides of the partition block 15 is related. The second lead screw 13 is threadedly connected to the moving block 8.

[0028] Furthermore, when the first rotating disk 12 rotates, the first rotating disk 12 drives the first lead screw 11 to rotate. As the first lead screw 11 rotates, the movable rod 5, which is threadedly connected to the first lead screw 11, can slide along the first sliding groove 4, wherein the sliding direction depends on the rotation direction of the first rotating disk 12.

[0029] When the second rotating disk 14 rotates, the second rotating disk 14 drives the second lead screw 13 to rotate. As the second lead screw 13 rotates, the moving block 8, which is threadedly connected to the second lead screw 13, can slide along the second slide groove 7. The sliding direction depends on the rotation direction of the second rotating disk 14. At the same time, a partition block 15 is provided inside the second slide groove 7. The helical direction of the second lead screw 13 is opposite on both sides of the partition block 15, so that the two moving blocks 8 can move towards each other.

[0030] The inside of the C-shaped clamping block 9 is hollow. An air guide pipe 16 is connected to one side of the C-shaped clamping block 9. The air guide pipe 16 is located away from the end that abuts the elastic block 10. The C-shaped clamping block 9 has several through holes 17 facing the end that abuts the elastic block 10.

[0031] The abutting elastic block 10 is slidably inserted into the inside of the C-shaped clamping block 9, and the end of the abutting elastic block 10 facing the C-shaped clamping block 9 is fixed with a plug plate 18.

[0032] The air guide pipe 16 is connected to an external air pump or other air-blowing device, and air is filled into the U-shaped clamping block 9 through the air guide pipe 16. The air is squeezed out along the through hole 17 and squeezes the contact elastic block 10. In this embodiment, the contact elastic block 10 is made of a highly resilient TPU elastomer. When clamping the workpiece, the contact elastic block can completely contact the surface of the workpiece. For workpieces of different shapes, the contact elastic block 10 deforms and wraps around the workpiece when it contacts the workpiece surface, while providing protection for the workpiece surface. At the same time, the other side of the contact elastic block 10 moves toward the end of the workpiece after being compressed and pressed by the air, so that both sides contact the contact elastic block 10, making the workpiece clamping stable.

[0033] The working principle of this utility model is as follows: By rotating the first rotating disk 12 to adjust the position of the moving rod 5, and simultaneously rotating the second rotating disk 14 to adjust the two moving blocks 8 to move quickly, the workpiece is clamped between the two abutting elastic bodies. The abutting elastic bodies can completely abut against the surface of the workpiece. For workpieces of different shapes, the abutting elastic block 10 deforms and wraps around the workpiece when it contacts the workpiece surface, while providing protection for the workpiece surface. At the same time, the other side of the abutting elastic block 10 moves towards the end of the workpiece after air compression and abutment, so that both sides contact the abutting elastic block 10, making the workpiece clamping stable.
