[0002] A machine tool refers to a machine that manufactures machines, also known as a mother machine or a tool machine, and is generally abbreviated as a machine tool. It is generally divided into metal cutting machine tools, forging machines, and woodworking machine tools, etc. In modern mechanical manufacturing, there are many methods for machining mechanical parts. In addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, for parts with relatively high precision requirements and relatively fine surface roughness requirements, they generally need to be finally processed by cutting on a machine tool. Machine tools play a major role in the construction of national economic modernization. When fixing parts on a machine tool, a fixture for machine tool processing is required.
[0003] However, the fixtures used in current machine tool processing on the market have different shapes of workpieces to face during the clamping operation, and cannot effectively clamp workpieces of different shapes. This will not only make the workpiece clamping unstable but also cause different degrees of wear to the workpiece, reducing the product quality and affecting the productivity.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following will disclose multiple embodiments of the present utility model in the form of drawings. For the sake of clarity, many physical details will be described together in the following description. However, it should be understood that these physical details are not used to limit the present utility model.

In addition, for the purpose of simplifying the drawings, some conventional structures and components will be shown in a simple schematic manner in the drawings.
[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, A fixture for machine tool processing with an anti-wear structure of the present utility model includes a workbench 1. Four semi-circular plates one 2 are in contact with the upper surface of the workbench 1. A semi-circular plate two 3 is slidably connected to the inner wall of each semi-circular plate one 2. Two semi-circular plates three 4 are slidably connected to the inner wall of each semi-circular plate two 3. Two semi-circular plates four 5 are slidably connected to the inner wall of each semi-circular plate three 4. Two contact blocks 6 are slidably connected to the inner wall of each semi-circular plate four 5. The bottom surfaces of each semi-circular plate one 2, semi-circular plate two 3, semi-circular plate three 4, semi-circular plate four 5, and contact block 6 are in contact with the upper surface of the workbench 1. A limiting groove 7 is opened inside the workbench 1. A motor 8 is fixedly connected to the bottom surface of the workbench. A bevel gear one 9 is fixedly connected to the output shaft of the motor 8. A bevel gear two 10 is meshed with the outer surface of the bevel gear one 9. A threaded rod 11 is fixedly connected to the inside of the bevel gear two 10. The left end and the right end of the threaded rod 11 are rotatably connected to the inner wall of the limiting groove 7. A sliding block 12 is threadedly connected to the outer surface of the threaded rod 11. The outer surface of the sliding block 12 is slidably connected to the inner wall of the limiting groove 7. When the contact block 6 is in contact with the workpiece, the contact block 6 slides inside the semi-circular plate four 5, the semi-circular plate four 5 slides inside the semi-circular plate three 4, the semi-circular plate three 4 slides inside the semi-circular plate two 3, and the semi-circular plate two 3 slides inside the semi-circular plate one 2, so that the contact block 6 adaptively changes the angle according to the shape of the workpiece, enabling the workpiece to be stably clamped by the contact block 6. The limiting groove 7 restricts the movement track of the sliding block 12, effectively preventing the sliding block 12 from derailing.
[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , there are four connecting arms 13 and four connecting blocks 14 on the upper surface of the workbench 1. The left end and the right end of each connecting arm 13 are rotatably connected to the outer surface of the corresponding connecting block 14. One end of the connecting arm 13 is flat and the other end is processed with a groove, so that the flat end can be closely attached to the groove. The four connecting arms 13 are connected into a whole through the four connecting blocks 14, enabling the connecting arm 13 to be stretched or contracted.
[0026] Please refer to Figure 1 , Figure 2 , Figure 3The upper surface of the sliding block 12 is fixedly connected to the bottom surface of the corresponding connecting block 14, and the upper surface of the workbench 1 is fixedly connected to the bottom surface of the connecting block 14 near the motor 8. The connecting block 14 fixed to the upper surface of the workbench 1 and the connecting block 14 fixed to the sliding block 12 are diagonally designed. The connecting block 14 fixed to the upper surface of the workbench 1 provides a fixed point for the connecting arm 13, and prevents the sliding block 12 from driving the four connecting arms 13 to deviate when the corresponding sliding block 12 moves, and the connecting arm 13 cannot drive the semicircular plate 2 to move. The remaining connecting blocks 14 are in sliding contact with the upper surface of the workbench 1. When the sliding block 12 drives the corresponding connecting block 14 to move, the sliding block 12 moves to the left and stretches the connected connecting arms 13 into a diamond shape, so that the semicircular plates 2 move away from each other. When the sliding block 12 moves to the right, the connected connecting arms 13 are recovered into a square shape, so that the semicircular plates 2 are close to each other to clamp the workpiece.
[0027] See also Figure 1 picture, Figure 2 , Figure 3 , above the workbench 1 are provided with fixed blocks 15 and four connecting plates 16 arranged at equal distances, the bottom surface of each fixed block 15 is fixedly connected to the upper surface of the relative semicircular plate 2 and the connecting arm 13, the left end and the right end of each connecting plate 16 are rotatably connected to the outer surface of the corresponding fixed block 15, the fixed block 15 provides a support point for the connecting plate 16, so that the connecting plate 16 can make the connecting arm 13 and the corresponding semicircular plate 2 move synchronously.
[0028] See also Figure 1 , Figure 2 , Figure 4 , above the threaded rod 11, there are fixed blocks 17 and four connecting plates 18 arranged at equal distances, the upper surface of each fixed block 17 is fixedly connected to the corresponding semicircular plate 2 and the bottom surface of the connecting arm 13, the left end and the right end of each connecting plate 18 are rotatably connected to the outer surface of the corresponding fixed block 17, the fixed block 17 provides a support point for the connecting plate 18, so that the connecting plate 18 can make the connecting arm 13 and the corresponding semicircular plate 2 move synchronously, so that when the sliding block 12 drives the corresponding connecting arm 13, the other two connecting arms 13 can drive the semicircular plate 2 connected by the connecting plate 18 to move synchronously.
[0029] See also Figure 4 Four fixed blocks 19 are provided above the sliding block 12. The upper surface of each fixed block 19 is fixedly connected to the bottom surface of the corresponding semicircular plate 2. The semicircular plate 2 provides a fulcrum for the fixed block 19. When the semicircular plate 2 moves, the fixed block 19 can move synchronously with it.
[0030] See also Figure 4, a cross-shaped plate 20 is fixedly connected to the upper surface of the workbench 1, and the outer surfaces of each of the third fixing blocks 19 are slidably connected to the inner wall of the cross-shaped plate 20. The cross-shaped plate 20 restricts the movement track of the third fixing blocks 19, prevents the phenomenon of deviation when the first semi-circular plates 2 clamp the workpiece, and enables the four first semi-circular plates 2 to cooperate with each other without collision, resulting in wear of the first semi-circular plates 2.
[0031] When the present utility model is in use: the motor 8 drives the first bevel gear 9 to mesh with the second bevel gear 10, and drives the threaded rod 11 to rotate. At the same time, the threaded rod 11 drives the sliding block 12 to move synchronously. The sliding block 12 drives the corresponding connecting block 14 to move. At the same time, the connecting block 14 drives the connecting arm 13 to extend or contract. At the same time, the connecting arm 13 drives the corresponding first connecting plate 16 and the second connecting plate 18 to move synchronously. The first connecting plate 16 and the second connecting plate 18 drive the corresponding first semi-circular plates 2 to move until the contact block 6 contacts the workpiece. At the same time, the contact block 6 slides inside the fourth semi-circular plate 5, the fourth semi-circular plate 5 slides inside the third semi-circular plate 4, the third semi-circular plate 4 slides inside the second semi-circular plate 3, and the second semi-circular plate 3 slides inside the first semi-circular plate 2. The contact block 6 is in close contact with the workpiece to clamp the workpiece and increase the force-bearing area of the workpiece, increasing the friction force to prevent wear.
[0032] The above is only the embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
