DETAILED DESCRIPTION

[0031] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] Reference Figure 1 And Figure 2The utility model provides an embodiment: a kind of heading machine pick processing positioning tool, including support frame 1, support frame 1 one side is fixedly connected with connecting plate one 2, support frame 1 one side is fixedly connected with motor 3, motor 3 output end is fixedly connected with transmission column 4, transmission column 4 top end is fixedly connected with transmission rod 5, transmission rod 5 side is fixedly connected with multiple connecting columns 6, connecting column 6 outer wall is slidably connected with slide rod 7, one side of slide rod 7 is fixedly connected with connecting block 8, one side of connecting block 8 is fixedly connected with sliding block 9, sliding block 9 inside is slidably connected with slide rail 10, the bottom of slide rail 10 is fixedly connected with connecting plate two 11, the bottom of connecting plate two 11 is fixedly connected with connecting frame one 12, connecting frame one 12 is fixedly connected with connecting plate one 2, the top of sliding block 9 is provided with connecting assembly, and connecting assembly is used to and is fixed with sliding block 9.

[0033] Specifically, when the workpiece needs to be positioned and processed, first, the limiting column 23 in the device plays a key supporting role, providing a stable placement platform for the workpiece to be processed, placing the workpiece to be processed on the top of the limiting column 23, ensuring that the workpiece is placed stably, laying a solid foundation for subsequent processing operations. Then, the power source is the motor 3, and the output end of the motor 3 can efficiently transmit power to drive the transmission column 4 to move up and down. The transmission column 4 acts as a power transmission bridge, accurately transmitting the power output by the motor 3 to the subsequent components. When the transmission column 4 moves up and down, the multiple slide rods 7 on both sides will slide on the outer wall of the connecting column 6. The connecting column 6 here plays a role in connecting and supporting the slide rods 7. Their sliding will pull the connecting block 8 to move. The connecting block 8 acts as a transmission link, transmitting the power of the slide rods 7. While the connecting block 8 moves, it will drive the sliding block 9 to slide on the slide rail 10. The slide rail 10 provides a stable sliding track for the sliding block 9, ensuring that the movement direction of the sliding block 9 is accurate. The sliding of the sliding block 9 will eventually cause the left and right symmetrical clamping blocks two 21 to move synchronously. The clamping block two 21 is directly in contact with the workpiece to be processed. Its role is to quickly and stably clamp the workpiece to be processed. Ultimately, it achieves the effect of quickly and stably clamping the workpiece to be processed, providing reliable protection for subsequent processing operations.

[0034] Referring to Figures 2-4 The connecting assembly includes connecting plate three 13, which is fixedly connected to the top of the sliding block 9. The top of the connecting plate three 13 is fixedly connected with a fixed column 14. The fixed column 14 is rotatably connected with a screw rod 15 inside. The top of the fixed column 14 is fixedly connected with a fixed plate 16. The top of the fixed plate 16 is fixedly connected with a support one 17. The support one 17 is rotatably connected with a clamping block one 18 inside. The clamping block one 18 is fixedly connected with a moving column 19 inside.

[0035] Specifically, when the fixture needs to be disassembled, maintained, or replaced, the screw 15 is rotated. During operation, the screw 15 plays a crucial adjustment role. When the fixture needs to be fixed, the screw 15 can be rotated. At this time, the screw 15 acts as a precise power transmitter. As the screw 15 rotates, it drives the moving column 19 to apply downward pressure. The moving column 19 is responsible for accurately transmitting the pressure. It transmits the pressure from the screw 15 downward. The pressure applied by the moving column 19 will further drive the clamping block 18 inside the bracket 17 to slide inward. The bracket 17 provides a stable installation and operating space for the clamping block 18, ensuring that the clamping block 18 can slide smoothly inside. The clamping block 18 directly contacts the fixture. When the clamping block 18 slides inward, it can firmly fix the fixture, providing a solid guarantee for subsequent processing operations.

[0036] Reference Figures 2-4 The screw 15 is threaded inside the movable column 19. The clamping block 18 is fixedly connected to the connecting frame 20. The clamping block 21 is fixedly connected to one side of the connecting frame 20. The clamping block 21 has a limit groove 24 inside. The top of the connecting plate 21 is fixedly connected to the bracket 22. The top of the bracket 22 is fixedly connected to the limit column 23.

[0037] Specifically, similarly, when it is necessary to loosen the clamp for loading and unloading, the moving column 19 is pressed upward by rotating the screw 15. In this process, the moving column 19 plays a key role again, changing the direction of the pressure. As the upward pressure of the moving column 19 is transmitted, the clamping blocks 18 on both sides will move outward at the same time, which achieves the effect of fast and stable loading and unloading of the clamp. This advantage of fast loading and unloading brings many benefits. It saves a lot of time and costs. In the past, the traditional clamp loading and unloading method required a lot of time and effort. Now, through this design, the efficiency of operation is greatly improved, and the production efficiency is significantly improved.

[0038] Working principle: when using the device, the workpiece to be machined is placed on the top of the limiting column 23, and after the workpiece to be machined is placed stably, the power is transmitted through the output end of the motor 3 to drive the transmission column 4 to move up and down, so that the plurality of slide rods 7 on both sides slide on the outer wall of the connecting column 6, so as to pull the connecting block 8 to move, thereby driving the sliding block 9 to slide on the slide rail 10, so that the left and right symmetric clamping blocks two 21 move synchronously, thereby achieving the effect of quickly and stably clamping the workpiece to be machined. When it is necessary to disassemble, maintain and replace the clamping block, the screw rod 15 can be rotated to drive the moving column 19 to apply pressure downward, and the clamping block one 18 in the support one 17 is driven to slide inward by the pressure applied by the moving column 19, so as to stably fix the clamp. Similarly, by rotating the screw rod 15, the moving column 19 applies pressure upward, so that the two clamping blocks one 18 move outward at the same time, thereby realizing the effect of quickly and stably disassembling and assembling the clamp. Quick assembly and disassembly save a lot of time cost, and the production efficiency is significantly improved.

[0039] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
