Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0021] The present utility model provides a Figures 1 to 4 dividing disc with adjustable rotation angle as shown, including a base 1. The top of the base 1 is rotatably connected to a connecting shaft 2 through a bearing. The top of the connecting shaft 2 is fixed with a carrier plate 3. A plurality of groups of arc grooves 4 are annularly formed on the carrier plate 3. A threaded column 5 is installed in the inner cavity of the arc groove 4. The bottom of the threaded column 5 is rotatably connected to a swivel ring 6 through a bearing. The top of the base 1 is movably provided with a mounting frame 7. A translation assembly 8 for moving the mounting frame 7 back and forth is arranged on the top of the base 1. A rotating shaft 9 is rotatably connected to the inner cavity of the mounting frame 7 through a bearing. A fixed cylinder 10 is fixed to the outside of the rotating shaft 9. Two sleeves 11 are sleeved on the outside of the fixed cylinder 10. A guide rail 12 is fixed to the outside of the sleeve 11. A drive motor 13 is installed on the side of the mounting frame 7. The output shaft of the drive motor 13 is key-connected to one end of the rotating shaft 9;

[0022] The angle between the threaded columns 5 can be adjusted through the arc groove 4 for adjusting the deflection angle of the carrier plate 3. Then, the rotating fixed cylinder 10 drives the sleeve 11 and the guide rail 12 to deflect the threaded column 5. The guide rail 12 can be adjusted on the outside of the fixed cylinder 10 in cooperation with the sleeve 11 to adapt to the distance between the threaded columns 5, facilitating the accurate deflection of the carrier plate 3.

[0023] The translation component 8 includes a groove 81 formed at the top of the base 1. The inner cavity of the groove 81 is rotatably connected with an adjusting screw rod 82 through a bearing. The outer side of the adjusting screw rod 82 is threadedly connected with a moving block 83 through a threaded sleeve. The moving block 83 is fixed to the bottom of the mounting frame 7. One end of the adjusting screw rod 82 penetrates to the outside of the base 1 and is fixed with a rotating handle. By rotating the adjusting screw rod 82, with the cooperation of the threaded sleeve, the moving block 83 is moved back and forth, so that the positions of the mounting frame 7 and the fixed cylinder 10 change, facilitating the guide rail 12 on the outside of the fixed cylinder 10 to be located directly below the threaded column 5.

[0024] A sliding groove 14 is formed on the outside of the fixed cylinder 10. The inner cavity of the sliding groove 14 is slidably connected with a sliding block 15. The outer side of the sliding block 15 penetrates through the sliding groove 14 and is fixed to the inner side of the sleeve 11. By sliding the sliding block 15 in the inner cavity of the sliding groove 14, it is convenient for the sleeve 11 to slide left and right on the outside of the fixed cylinder 10 to adjust the position of the guide rail 12, and at the same time ensure that the sleeve 11 and the fixed cylinder 10 maintain the same rotation speed.

[0025] A counterbore is formed on the outside of the sleeve 11, and a locking screw 16 is threadedly connected to the inner cavity of the counterbore. The locking screw 16 penetrates to the inner cavity of the sleeve 11 and fits with the fixed cylinder 10. Through the cooperation of the locking screw 16, it is convenient to limit and fix the sleeve 11 and the fixed cylinder 10 to prevent the sleeve 11 from sliding on the outside of the fixed cylinder 10, resulting in a change in the distance between the guide rails 12 again.

[0026] A limiting ring 17 is fixed to the outside of the threaded column 5. The limiting ring 17 fits against the bottom of the bearing plate 3. A locking nut 21 located above the bearing plate 3 is threadedly connected to the top of the threaded column 5. Through the cooperation of the limiting ring 17 and the locking nut 21, it is convenient to stably install the threaded column 5 in the arc-shaped groove 4 and at the same time convenient to adjust the position of the threaded column 5.

[0027] Scale lines 18 are sprayed on the top of the bearing plate 3. The scale lines 18 are located outside the arc-shaped groove 4. Through the setting of the scale lines 18, it is convenient to control the included angle between the threaded columns 5 and ensure the accuracy of angle adjustment.

[0028] On both sides of the top of the base 1, limit grooves 19 are provided. At the bottom of the mounting frame 7, limit blocks 20 are fixed and extend into the inner cavity of the limit grooves 19. By sliding the limit blocks 20 in the inner cavity of the limit grooves 19, it is convenient to limit the mounting frame 7, preventing the mounting frame 7 from shaking on the top of the base 1, resulting in a change in the position between the guide rail 12 and the threaded column 5, and affecting the accuracy of the rotation angle of the bearing plate 3.

[0029] During specific use, adjust the position of the threaded column 5 in the arc-shaped groove 4 according to the scale line 18, and then tighten the lock nut 21 and cooperate with the limit ring 17 to stably install the threaded column 5 on the bearing plate 3. Subsequently, slide the sleeve 11 so that the parallel section of the guide rail 12 is located between the two groups of threaded columns 5, and at the same time make the rotary ring 6 fit the guide rail 12. Then, use the lock screw 16 to fix the sleeve 11 and the fixed cylinder 10. Then, rotate the handle to drive the adjusting screw 82 to rotate, and drive the moving block 83 and the mounting frame 7 to move back and forth on the top of the base 1 by using the threaded sleeve, so that the fixed cylinder 10 is located directly below the threaded column 5. At the same time, start the driving motor 13. The driving motor 13 drives the fixed cylinder 10 to rotate through the rotating shaft 9. Then, the fixed cylinder 10 drives the guide rail 12 to rotate through the sleeve 11. The guide rail 12 fits the rotary ring 6, and at the same time drives the bearing plate 3 to rotate through the connecting shaft 2 by the threaded column 5. During the contact process between the parallel section of the guide rail 12 and the rotary ring 6, the bearing plate 3 can be kept stable.
