[0021] As shown in Figure 1 , Figure 2 and Figure 4As shown in the figure, an adjustable workpiece fixture includes a workbench 1. A receiving groove 2 is formed on the top surface of the workbench 1. On one side of the inner wall of the receiving groove 2, a lead screw stepping motor 3 is fixed. The outer wall of the output shaft of the lead screw stepping motor 3 is threadedly connected with two moving blocks 4. A clamping block 5 is fixed on the top surface of the moving block 4. A limiting groove 6 is formed on one side of the clamping block 5. Through holes 7 are formed on both the left and right sides of the clamping block 5, and the positions of the two through holes 7 are different. The through holes 7 communicate with the limiting groove 6. A rotating column 8 is rotatably arranged on the inner wall of the limiting groove 6. A gear 9 is fixed at one end of the rotating column 8. A connecting plate 10 is slidably connected to the inner wall of the through hole 7. A rack 11 is fixed on one side of the connecting plate 10. The rack 11 meshes with the gear 9. A fixing plate 12 is fixed on one side of the connecting plate 10.

[0022] In use, through the cooperation of the gear 9 and the rack 11, it is convenient for the staff to adjust the fixture according to the size of the workpiece, so that the fixture can adapt to workpieces of different models, thereby improving the adaptability and flexibility of the fixture, and further improving the use effect of the fixture. At the same time, the gear 9 and the rack 11 can provide a stable clamping force for the fixture, so that the fixture can meet the clamping requirements of different workpieces in cooperation with the lead screw stepping motor 3, thereby improving the clamping efficiency of the fixture.

[0023] As Figure 1 , Figure 2 and Figure 4 shown, a limiting hole 13 is formed at the rear side of the clamping block 5. The limiting hole 13 communicates with the limiting groove 6. A positioning pin 14 is slidably arranged on the inner wall of the limiting hole 13. An anti-slip pad 15 is fixed on one side of the fixing plate 12.

[0024] In use, the rotating column 8 and the gear 9 can be limited and fixed through the positioning pin 14, preventing the gear 9 from rotating back after the fixing plate 12 fixes the workpiece, thereby ensuring the clamping efficiency of the fixture. The anti-slip pad 15 can increase the friction between the workpiece and the fixing plate 12, preventing the workpiece from slipping during the clamping process, so that the fixture can stably clamp and fix the workpiece. At the same time, the flexible material of the anti-slip pad 15 can provide a force buffer for the workpiece, preventing the workpiece from being damaged due to excessive clamping by the fixing plate 12, thereby improving the integrity of the workpiece.

[0025] As Figures 1 - 4 shown, sliding blocks 16 are fixed on both the left and right sides of the moving block 4. Two L-shaped plates 17 are fixed on the inner wall of the receiving groove 2. A sliding hole 18 is formed on one side of the L-shaped plate 17. The sliding block 16 is slidably connected with the sliding hole 18. The top surface of the L-shaped plate 17 and the bottom surface of the fixing plate 12 are on the same horizontal plane. A placement groove 19 is formed on the left side of the workbench 1. A collection box 20 is slidably arranged on the inner wall of the placement groove 19. An outlet hole 21 is formed on the bottom surface of the inner wall of the receiving groove 2. The outlet hole 21 communicates with the placement groove 19.

[0026] In use, through the cooperation of the sliding block 16 and the sliding hole 18, the moving block 4 can be kept moving horizontally, preventing the moving block 4 from wobbling during movement, so that the fixture can stably clamp and fix the workpiece, thereby improving the processing efficiency of the workpiece. The L-shaped plate 17 can provide force support for the workpiece, preventing the workpiece from wobbling during clamping, thereby improving the stability of the fixture and the workpiece. The debris generated during workpiece processing can be collected by the collection box 20, facilitating the staff to centrally collect and process the debris in the collection box 20, thus saving labor and time costs. At the same time, the inclined surface design of the discharge hole 21 can facilitate the debris to fall into the collection box 20 more smoothly, effectively preventing the accumulation of debris.
