[0002] With the continuous development of industrial production, metal workpieces play an increasingly important role in various manufacturing industries. In this field, the precise processing of metal workpieces is particularly crucial, especially in drilling processes. How to effectively fix and clamp metal workpieces of different sizes has become an important factor in improving production efficiency and processing accuracy. Therefore, developing an efficient and simple positioning stage device to achieve flexible clamping and precise positioning of metal workpieces is of practical significance for improving processing technology and increasing production efficiency.

[0003] Most traditional positioning tables are equipped with adjusting screws or manual knobs. Operators can move the position of the worktable or fixture by rotating these devices. The structure of these existing fixtures is generally quite complex, and they usually require manual adjustment to accommodate workpieces of different sizes. Moreover, the adjustment process of the fixtures is often time-consuming and it is difficult to ensure that the clamping is accurate enough each time.

[0004] Although traditional clamping structures can achieve clamping on relatively stable workpieces, when it is necessary to clamp metal workpieces of different sizes, many positioning tables have simple clamping structures, which are difficult to adapt to workpieces of various shapes and sizes quickly, and are prone to unstable fixation or difficulty in adjustment. Utility Model Content

[0010] Furthermore, the limiting component includes a locking block, the outer wall of which is slidably connected to the outer wall of the sliding rod, a baffle is fixedly connected to one side of the outer wall of the locking block, a spring is fixedly connected to one side of the outer wall of the baffle, and a fixing plate is fixedly connected to one side of the outer wall of the spring.

[0011] Furthermore, the workbench is provided with a guide groove, which is used to guide the connecting rod.

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] Reference Figures 1-4 This utility model provides an embodiment of a positioning table for drilling metal workpieces, comprising a worktable 3, a support frame 2 fixedly connected to the upper surface of the worktable 3, the support frame 2 providing stable support and a support structure, a cylinder 1 providing power to drive the clamping action of the fixture to achieve tight clamping of the metal workpiece, a clamping assembly provided inside the worktable 3, the clamping assembly including the cylinder 1, the lower surface of the cylinder 1 fixedly connected to the upper surface of the support frame 2, a clamping plate 15 fixedly connected to the output end of the cylinder 1, the movement of the clamping plate 15 being driven by the output of the cylinder 1 to ensure that it can move quickly and reliably to clamp the workpiece, and a fixing sleeve 7 fixedly connected to the lower surface of the clamping plate 15. A second fixed sleeve 8 is provided below the first fixed sleeve 7, and a connecting rod 9 is provided below the first fixed sleeve 7. A rack 10 is fixedly connected to the lower surface of the connecting rod 9. The rack 10 is used to mesh with the gear 12 to achieve precise displacement of the clamping assembly. The gear 12 is meshed and connected to one side of the outer wall of the rack 10. The rack 14 is meshed and connected to the outer wall of the gear 12. The rack 14 is used to drive the synchronous movement of other components to ensure the coordination of the clamping action. A rotating shaft 13 is fixedly connected to the lower surface of the gear 12. A turntable 11 is rotatably connected to the outer wall of the rotating shaft 13. A clamping plate 4 is provided above the worktable 3. The clamping plate 4 is driven by the cylinder 1 to move relative to the clamping plate 2 15 to clamp the workpiece.

[0026] Reference Figures 2-4 A fixed plate 6 is fixedly connected to the outer wall of a fixed sleeve 7. A sliding assembly is provided on the inner wall of the fixed sleeve 7. A limiting assembly is provided inside the fixed sleeve 7. The sliding assembly includes a slider 16, whose outer wall is slidably connected to the inner wall of the fixed sleeve 7. The slider 16 uses the sliding design of the inner wall to achieve relative movement with the fixed sleeve 7. A sliding rod 18 is fixedly connected to the lower surface of the fixed plate 6. The design of the sliding rod 18 allows the clamp to be flexibly adjusted within a certain range, enhancing the adaptability of the clamping process. A slider 27 is slidably connected to the outer wall of the sliding rod 18. The limiting assembly includes a locking block 19, whose outer wall is slidably connected to the outer wall of the sliding rod 18. A baffle 20 is fixedly connected to one side of the outer wall of the locking block 19. A spring 21 is fixedly connected to one side of the outer wall of the baffle 20. The spring 21 can provide a restoring force to ensure that the clamp can quickly return to its initial state during the release operation. A fixed plate 22 is fixedly connected to one side of the outer wall of the spring 21.

[0027] Reference Figures 1-4 The workbench 3 has a guide groove 5 inside, which guides the connecting rod 9 to ensure that the connecting rod 9 does not tilt or deviate during movement, thus ensuring the accuracy and reliability of the clamping action. The guide groove 5 guides the connecting rod 9. The fixed plate 6 has a sliding groove 23 inside, which is used for the sliding of the spring 21. The sliding groove 23 allows the spring 21 to move smoothly during clamping and release, providing a stable rebound effect. The outer wall of the latch 19 is slidably connected to the inside of the fixed plate 6, the outer wall of the spring 21 is slidably connected to the inner wall of the fixed plate 6, and the outer wall of the slider 17 is slidably connected to the inner wall of the fixed sleeve 7.

[0028] Working principle: When it is necessary to clamp a metal workpiece, the output end of cylinder 1 first pushes clamping plate 4 and clamping plate 15 to move. The function of cylinder 1 is to provide the necessary power so that clamping plate 4 and clamping plate 15 can clamp quickly and effectively, achieving a stable clamping of the workpiece. When clamping plate 15 is pushed to move, the movement of clamping plate 15 is transmitted to connecting rod 9 through fixed sleeve 7, which in turn effectively pushes rack 10 to move. The movement of rack 10 drives gear 12 to rotate, and the rotation of gear 12 causes rack 14 to move. Through this synchronous movement, clamping plate 4 and clamping plate 15 move relative to each other, forming a clamping of the metal workpiece. This design effectively adapts to metal workpieces of different sizes, achieving flexible clamping effects and meeting various processing needs. When clamping plates 1-4 and 2-15 are severely worn and need to be replaced, clamping plates 1-4 and 2-15 are first pressed down, causing the locking block 19 to slide out along the outer wall of slider 2-17. The locking block 19 is designed to provide reliable positioning and limiting during clamping and release, ensuring the stability of the clamping plates, thereby enabling the disassembly of clamping plates 1-4 and 2-15. When clamping plates 1-4 and 2-15 are pressed down, spring 21 is subjected to compressive force. The function of spring 21 is to provide restoring force, ensuring that the locking block 19 can move effectively along the sliding groove 23 and lock into the underside of slider 1-16. This design allows clamping plates 1-4 and 2-15 to be installed quickly, improving the convenience and efficiency of changing fixtures.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
