[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0025] Reference Figures 1-3This utility model provides an embodiment of an automatic chip removal and collection device for rivet nuts, comprising a fixed plate 1. Two motors 2 are fixedly connected to the rear side of the fixed plate 1. A first worm gear 4 is fixedly installed at the output end of the right motor 2, and a second worm gear 5 is fixedly installed at the output end of the left motor 3. The first worm gear 4 is rotatably connected to the fixed plate 1, and the second worm gear 5 is rotatably connected to the fixed plate 1. A first worm wheel 6 is meshed with the upper side of the first worm gear 4, and a second worm wheel 7 is meshed with the upper side of the second worm gear 5. A connecting... A connecting cover 9 is fixedly connected inside the rod 8 and the second worm gear 7. The connecting rod 8 is rotatably connected to the connecting cover 9 and to the fixing plate 1. A control cover 10 is provided on the left side of the connecting cover 9. Four chip removal strips 11 are rotatably connected to the surface of the control cover 10. A first threaded rod 13 is fixedly connected to the left end of the connecting rod 8. A control ring 12 is meshed with the surface of the first threaded rod 13. The control ring 12 is rotatably connected to the four chip removal strips 11. A quick-release assembly is provided on the right side of the control cover 10. The quick-release assembly is used to quickly replace the chip removal assembly.

[0026] Specifically, when the right-side motor 2 drives the first worm gear 4 to rotate, the rotation of the first worm gear 4 will drive the first worm wheel 6 to rotate, the rotation of the first worm wheel 6 will drive the connecting rod 8 to rotate, the rotation of the connecting rod 8 will drive the first threaded rod 13 to rotate, the rotation of the first threaded rod 13 will drive the control ring 12 to move left and right. The leftward movement of the control ring 12 will cause the chip removal strip 11 to extend and retract, and the rightward movement of the control ring 12 will cause the chip removal strip 11 to open. The two motors 2 simultaneously drive the first worm gear 4 and the second worm gear 5 to rotate, which in turn will drive the first worm wheel 6 and the second worm wheel 7 to rotate simultaneously. The simultaneous rotation of the first worm wheel 6 and the second worm wheel 7 will drive the connecting rod 8 and the connecting cover 9 to rotate simultaneously, which in turn will drive the control cover 10 and the control ring 12 to rotate simultaneously, which in turn will drive the chip removal strip 11 to rotate. This achieves adaptive adjustment of the size of the chip removal head for chip removal.

[0027] Reference Figure 5 and Figure 6 The quick-release assembly includes a sliding cover 17, which is fixedly connected to a connecting cover 9. A second groove 19 is provided on the inner wall of the sliding cover 17, and a ball 15 is provided inside the second groove 19. The sliding cover 17 is slidably connected to a control cover 10. A first groove 18 is provided on the surface of the control cover 10. An outer cover 14 is slidably connected to the surface of the sliding cover 17. A spring 16 is fixedly connected to the inner wall of the outer cover 14, and the spring 16 is fixedly connected to the sliding cover 17.

[0028] Specifically, when the outer cover 14 is moved under force, it will compress the spring 16 to give it elastic potential energy. At this time, the outer cover 14 cannot limit the ball 15 to be stuck in the first groove 18. When the ball 15 is dislodged from the first groove 18, the control cover 10 can be pulled out to remove the chip remover. The outer cover 14 is then subjected to force to replace the chip remover. The control cover 10 is then inserted into the sliding cover 17. The force on the outer cover 14 is released, and the spring 16 causes the outer cover 14 to return to its original position. The outer cover 14 limits the ball 15, and the ball 15 is stuck in the first groove 18, limiting the control cover 10.

[0029] Reference Figure 1 A base 20 is fixedly connected to the top of the fixing plate 1, and a collection box 21 is fixedly connected to the left side of the base 20.

[0030] Specifically, the base 20 is used to fix the position of the fixing plate 1, and the collection box 21 is used to collect debris.

[0031] Reference Figure 1 An air pump 24 is provided on the left side of the base 20. The output end of the air pump 24 is fixedly connected to the collection box 21, and the input end of the air pump 24 is fixedly connected to the suction pipe 25.

[0032] Specifically, the air pump 24 is used to draw debris into the collection box 21 through the air extraction pipe 25.

[0033] Reference Figure 1 The collection box 21 has a drawer 22 that slides inside, and a handle 23 is fixedly connected to the back of the drawer 22.

[0034] Specifically, drawer 22 facilitates cleaning of debris inside collection box 21, and handle 23 makes it easy to pull out drawer 22.

[0035] Reference Figure 1 and Figure 4 A connecting strip 27 is fixedly connected to the top of the base 20, and a connecting column 26 is fixedly connected to the top of the base 20.

[0036] Specifically, the base 20 is used to fix the positions of the connecting strip 27 and the connecting post 26.

[0037] Reference Figure 1 and Figure 4 The top of the connecting column 26 is fixedly connected to a slide 29, and two clamping plates 3 are slidably connected inside the slide 29.

[0038] Specifically, the connecting column 26 is used to fix the position of the carriage 29, and the clamping plate 3 slides on the carriage 29.

[0039] Reference Figure 1 and Figure 4 The two clamping plates 3 are internally meshed with a second threaded rod 30, and a rotating rod 28 is fixedly connected to the rear side of the second threaded rod 30. The rotating rod 28 is rotatably connected to the connecting bar 27.

[0040] Specifically, the connecting strip 27 is used to fix the position of the rotating rod 28. When the rotating rod 28 is subjected to force and rotates, it will drive the second threaded rod 30 to rotate. When the second threaded rod 30 rotates, it will drive the two clamping plates 3 to retract and clamp the rivet nut.

[0041] Working principle: When the size of the chip removal head needs to be adjusted for chip removal, motor 2 drives the first worm 4 and the second worm 5 to rotate simultaneously. The first worm 4 and the second worm 5 drive the first worm wheel 6 and the second worm wheel 7 to rotate simultaneously, which in turn drives the connecting rod 8 and the connecting cover 9 to rotate simultaneously. The rotation of the connecting rod 8 and the connecting cover 9 drives the control cover 10 and the control ring 12 to rotate simultaneously. The rotation of the control cover 10 and the control ring 12 drives the chip removal strips 11 to rotate, thereby performing chip removal. When motor 2 on the right works alone, it drives the first worm 4 to rotate. The first worm 4 drives the first worm wheel 6 to rotate. The first worm wheel 6 drives the connecting rod 8 to rotate. The connecting rod 8 drives the first threaded rod 13 to rotate. The rotation of the first threaded rod 13 drives the control ring 12 to move left and right. When the control ring 12 moves to the left, it drives the four chip removal strips 11 connected to it to extend and retract. When the control ring 12 moves to the right, it drives the chip removal strips 11 to open. This achieves adaptive adjustment of the size of the chip removal head for chip removal.

[0042] When the shaving head needs to be replaced, force is applied to the outer cover 14. The outer cover 14 moves under force, which compresses the spring 16, giving the spring 16 elastic potential energy. At this time, the outer cover 14 cannot limit the ball 15 in the second groove 19 on the inner wall of the sliding cover 17. The ball 15 will not be stuck in the first groove 18 on the surface of the control cover 10. When the ball 15 is dislodged from the first groove 18, the control cover 10 can be pulled out, thereby removing the shaving head. Then, the outer cover 14 is subjected to force again, and a new shaving head is installed. The control cover 10 is inserted into the sliding cover 17, and the force on the outer cover 14 is released. The spring 16 causes the outer cover 14 to return to its original position, and the outer cover 14 limits the ball 15. The ball 15 is stuck in the first groove 18, thereby limiting the control cover 10 and completing the replacement of the shaving head.

[0043] 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.
