[0023] Please refer to Figure 1-8, An embodiment provided by the present utility model: A fixture for shaft products, including a base 1, a motor 3, a movable frame 7 and a movable rod 20. The middle of the outer wall of the base 1 is fixedly connected with a support rod 28. The left side of the outer wall of the base 1 is fixedly connected with a fixed frame 2, and a motor 3 is installed on the upper side inside the fixed frame 2. The upper end of the outer wall of the base 1 is provided with a movable frame 7, and a card slot 8 is opened in the middle of the inside of the movable frame 7. The right end of the outer wall of the base 1 is connected with a movable rod 20 through a bearing;

[0024] Further, a chute 4 is opened in the middle of the inside of the fixed frame 2, and a first screw rod 5 is connected to the middle of the inner wall of the chute 4 through a bearing. The upper end of the outer wall of the first screw rod 5 is connected to the output end of the outer wall of the motor 3. The outer wall surface of the first screw rod 5 is threadedly connected with a first nut 6, and the outer wall surface of the upper movable frame 7 is fixed to the end of the outer wall of the first nut 6. This structure can drive the upper movable frame 7 to move vertically in height after the motor 3 is started by remote control.

[0025] Further, a second screw rod 9 is inserted into the middle of the inner wall of the card slot 8, and a limit groove 10 is opened on the outer wall surface of the second screw rod 9. A limit block 11 is fixedly connected to the inner wall surface of the card slot 8, and the outer wall surface of the limit block 11 is adapted to the outer wall surface of the limit groove 10. The outer wall surface of the second screw rod 9 is threadedly connected with a second nut 13, and a first bevel gear 14 is fixedly connected to the outer wall surface of the second nut 13. This structure can perform threaded movement through the second screw rod 9 and the second nut 13, and through the limiting use of the limit block 11, the second screw rod 9 can only be used for horizontal position movement.

[0026] Further, rubber heads 12 are fixedly connected to both ends of the outer wall of the second screw rod 9, and a roller 27 is installed at the end of the outer wall of the upper second screw rod 9. A rubber pad is provided on the outer wall surface of the roller 27, and the roller 27 is vertically and horizontally flush with the rubber head 12. This structure clamps the shaft product through six rubber heads 12, and at the same time, when the shaft product is working, the six upper rollers 27 can change the vertical position on the outer wall of the shaft product to adapt to shaft products in different working positions.

[0027] Further, a second bevel gear 16 is meshed with the outer wall surface of the first bevel gear 14, and a first rotating rod 15 is fixedly connected to the middle of the outer wall of the second bevel gear 16. A third bevel gear 17 is fixedly connected to the middle of the outer wall of the first rotating rod 15, and a fourth bevel gear 19 is meshed with the outer wall surface of the third bevel gear 17. A second rotating rod 18 is fixedly connected to the middle of the outer wall of the fourth bevel gear 19. This structure is respectively meshed with the outer wall surfaces of six first bevel gears 14, so that when the fourth bevel gear 19 rotates the third bevel gear 17, it will simultaneously drive six rubber heads 12 and rollers 27 to perform clamping movements.

[0028] Furthermore, a fifth bevel gear 21 is sleeved on the outer wall surface of the movable rod 20, and a sleeve block 22 is fixedly connected to the lower end of the outer wall of the fifth bevel gear 21. A guide groove 23 is formed on the outer wall surface of the sleeve block 22. A snap ring 24 is sleeved on the outer wall surface of the second rotating rod 18. A connecting rod 25 is fixedly connected to the outer wall surface of the snap ring 24, and a clamping block 26 is fixedly connected to the end of the outer wall of the connecting rod 25. The outer wall surface of the clamping block 26 is adapted to the inner wall surface of the guide groove 23, and the outer wall surface of the fifth bevel gear 21 meshes with the end of the second rotating rod 18. When this structure is in use, by simply rotating the movable rod 20, the internal parts of the movable frame 7 can be made to move, which is convenient and fast.

[0029] Working principle: When in use, the whole can be placed at the position for using the shaft product. Then, the shaft product is placed on the upper end of the outer wall of the base 1 through the support rod 28. At the same time, the two movable frames 7 are located on the outer wall of the shaft product. At this time, the movable rod 20 can be rotated to make it rotate, and at the same time, the fifth bevel gear 21 is driven to rotate. When the fifth bevel gear 21 rotates, it will drive the end of the second rotating rod 18, so that the second rotating rod 18 drives the fourth bevel gear 19 to rotate. The snap ring 24 and the sleeve block 22 will not be affected. When the sleeve block 22 rotates, it will rotate the outer wall surface of the clamping block 26 through the guide groove 23. When the fourth bevel gear 19 rotates, it will drive the third bevel gear 17 to rotate, and the third bevel gear 17 will drive the first rotating rod 15 to rotate. The first rotating rod 15 drives the first bevel gear 14 and the second screw sleeve 13 to rotate. When the first bevel gear 14 rotates, it will simultaneously drive the second bevel gear 16 on the other side, so as to drive the overall parts inside the movable frame 7 to rotate. Through the threaded movement of the second screw sleeve 13 on the second screw rod 9, the second screw rod 9 can be driven to change its horizontal position. And the second screw rod 9 does not rotate but moves horizontally through the mutual adaptation of the outer wall limiting groove 10 and the limiting block 11. At this time, the six rubber heads 12 will clamp the bottom of the shaft product placed in the middle, and the six rollers 27 on the upper side will simultaneously clamp the outer wall of the shaft product. Then, the motor 3 can be controlled by remote control to operate, and the first screw rod 5 at the output end is driven to perform threaded movement with the first screw sleeve 6 to change the vertical position of the first screw sleeve 6, so as to drive the upper movable frame 7 to move vertically. In this way, the machine can thread the shaft product downward while maintaining clamping and moving downward, so as to be stable on the lower side of the processing position while changing with the processing depth, thus ensuring the stability during processing. The above is the whole working principle of the present utility model.
