[0002] Rivet nuts are fasteners used on thin plates or sheet metal. In the processing industry, the displacement of parts during processing often leads to a decrease in the quality of the finished product. Therefore, it is necessary to develop a punching and positioning tool for anti-displacement rivet nuts.

In previous technologies, rivet nut punching positioning fixtures lacked clamping and fixing functions, and the rivet nuts may not remain stable during installation, easily being affected by external forces and shifting. This leads to inaccurate positioning of the rivet nuts, which in turn affects the accuracy and stability of the entire assembly. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a punching and positioning fixture for anti-offset rivet nuts, including a support platform 1, a base 2 fixedly connected to the inner bottom wall of the support platform 1, a hydraulic cylinder 3 fixedly connected to the upper surface of the base 2, a toothed column 4 fixedly connected to the output end of the hydraulic cylinder 3, a support shaft 8 fixedly connected inside the support platform 1, a sliding shaft 7 rotatably connected to the outer wall of the support shaft 8, a lower surface of the toothed column 4 slidably connected to the upper surface of the sliding shaft 7, a half gear 5 meshing with the tooth end of the toothed column 4, a rotating shaft 6 rotatably connected inside the half gear 5, a rotating plate 9 fixedly connected to the outer wall of the rotating shaft 6 fixedly connected to the inside of the support platform 1, a driving assembly provided on the upper surface of the half gear 5, and the driving assembly being used to drive the clamping of the rivet nut for punching and positioning.

[0025] Specifically, the support platform 1 fixes the position of the base 2, the base 2 fixes the position of the hydraulic cylinder 3, and the hydraulic cylinder 3 drives the gear 4 to reciprocate. Simultaneously, the sliding shaft 7 supports the position of the gear 4, the support shaft 8 supports the position of the sliding shaft 7, and the support platform 1 fixes the position of the support shaft 8. The movement of the gear 4 drives the half gear 5 to rotate, and the rotating shaft 6 supports the position of the half gear 5 during rotation. The support platform 1 also fixes the position of the rotating shaft 6. The rotation of the half gear 5 drives the rotating plate 9 to rotate and adjust its angle. This allows for precise positioning of the rivet nut, ensuring it is in the correct machining position. This helps avoid machining defects or scrap due to positional errors, improving product processing quality.

[0026] Reference Figure 4 and Figure 5 The drive assembly includes a base plate 10, the lower surface of which is fixedly connected to the upper surface of the rotating plate 9, and a motor 12 fixedly connected to the upper surface of the base plate 10. A worm gear 13 is fixedly provided at the output end of the motor 12.

[0027] Specifically, the rotating plate 9 drives the base plate 10 to rotate, the base plate 10 fixes the position of the motor 12, and the starting motor 12 drives the worm gear 13 to rotate.

[0028] Reference Figure 4 and Figure 5 A support frame 11 is fixedly connected to the upper surface of the base plate 10. The outer wall of the worm gear 13 is rotatably connected to the inside of the support frame 11. The tooth end of the worm gear 13 is meshed with a worm wheel 15. The inside of the worm wheel 15 is rotatably connected to a first fixed shaft 14. The lower surface of the first fixed shaft 14 is fixedly connected to the upper surface of the base plate 10. The outer wall of the worm wheel 15 is fixedly connected to a first rotating shaft 16. The outer wall of the first rotating shaft 16 is fixedly connected to a first rotating frame 17. The lower surface of the first rotating frame 17 is rotatably connected to the upper surface of the base plate 10. The inside of the first rotating frame 17 is rotatably connected to... There is a third rotating shaft 23, and a traction block 18 is fixedly connected to the outer wall of the third rotating shaft 23. A clamping frame 19 is fixedly connected to the outer wall of the traction block 18. A second rotating shaft 22 is fixedly connected to the inside of the traction block 18. A second rotating frame 21 is rotatably connected to the outer wall of the second rotating shaft 22. The lower surface of the second rotating frame 21 is rotatably connected to the upper surface of the base plate 10. A second fixed shaft 20 is rotatably connected to the inside of the second rotating frame 21. The outer wall of the second fixed shaft 20 is fixedly connected to the inside of the worm gear 15. The outer wall of the second fixed shaft 20 is rotatably connected to the inside of the support frame 11.

[0029] Specifically, the base plate 10 fixes the position of the support frame 11, which in turn supports the worm gear 13. The rotation of the worm gear 13 drives the worm wheel 15 to rotate. Simultaneously, the first fixed shaft 14 supports the position of the worm wheel 15, and the base plate 10 fixes the position of the first fixed shaft 14. The rotation of the worm wheel 15 causes the first rotating shaft 16 to drive the first rotating frame 17 to rotate. The base plate 10 supports the position of the first rotating frame 17 during rotation. The rotation of the first rotating frame 17 causes the third rotating shaft 23 to drive the traction block 18 to move. The traction block 18 fixes the third rotating shaft 23. The function of shaft 23 is to simultaneously drive the second rotating frame 21 to rotate via the rotation of the worm gear 15, and to support the position of the second fixed shaft 20 via the support frame 11. The base plate 10 supports the position of the second rotating frame 21 during rotation. The rotation of the second rotating frame 21 causes the traction block 18 to move via the second rotating shaft 22. Thus, the rotation of the first rotating frame 17 and the second rotating frame 21, in turn, causes the traction block 18 to move horizontally via the cooperation of the third rotating shaft 23 and the second rotating shaft 22. The movement of the traction block 18 then causes the clamping frame 19 to move horizontally to clamp the rivet nut.

[0030] Working principle: During use, the hydraulic cylinder 3 is activated to push the gear column 4 to slide under the support of the sliding shaft 7. At the same time, the position of the sliding shaft 7 is fixed by the support shaft 8. The movement of the gear column 4 drives the meshing half gear 5 to rotate under the support of the rotating shaft 6. The rotation of the half gear 5 drives the rotating plate 9 to rotate, and the rotation of the rotating plate 9 drives the base plate 10 to rotate and adjust the angle. The angle adjustment function allows the operator to adjust the angle of the tooling according to actual needs to adapt to the inclination of different workpiece surfaces or special installation requirements. After the angle is adjusted and fixed, the punching operation is performed to ensure that the installation position of the rivet nut is accurate. Through precise positioning and adjustment, the installation position of the rivet nut can be ensured to be accurate, reducing the time of repeated positioning and adjustment caused by offset, improving production efficiency, and thus improving the overall quality and reliability of the product.

[0031] The motor 12 drives the worm gear 13 to rotate under the support of the support frame 11. The rotation of the worm gear 13 drives the meshing worm wheel 15 to rotate under the support of the first fixed shaft 14. The position of the first fixed shaft 14 is fixed by the base plate 10. The rotation of the worm wheel 15 drives the first rotating frame 17 to rotate on the upper surface of the base plate 10 by the first rotating shaft 16. The rotation of the base plate 10 drives the traction block 18 to reciprocate by the third rotating shaft 23. At the same time, the rotation of the worm wheel 15 drives the second rotating frame 21 to rotate on the upper surface of the base plate 10 by the second fixed shaft 20. The rotation of the second rotating frame 21 drives the traction block 18 to move horizontally back and forth via the second rotating shaft 22. Thus, the combined action of the second rotating shaft 22 and the second rotating frame 21 drives the traction block 18 to move back and forth, causing the clamping frame 19 to move horizontally to clamp the rivet nut. The clamping frame 19 accurately positions the rivet nut, keeping it in a fixed position during the punching process. This helps ensure the accuracy and consistency of the processing results and prevents the workpiece from shifting.
