[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , a fixing tooling for worm milling processing of the present invention includes a base 1. A plurality of side seats 2 are provided on the periphery of the base 1. A side plate 3 is provided at the outer end of the side seat 2. A positioning rod 4 inserted into the inside of the side seat 2 is provided in the middle of the side plate 3, and the positioning rod 4 can move within the side seat 2. A top rod 6 is provided at the upper end of the side plate 3. A bottom rod 5 is provided at the lower end of the side plate 3. The bottom rod 5 and the top rod 6 are respectively located at the lower end and the upper end of the side seat 2. A driving assembly capable of driving the bottom rod 5 to move is provided at the lower end of the side seat 2. A first clamping block 10 is fixedly provided at one end of the top rod 6. A second clamping block 11 is provided at the upper end of the first clamping block 10. A screw rod 12 inserted into the inside of the first clamping block 10 is provided at the lower end of the second clamping block 11. The screw rod 12 is in threaded connection with the first clamping block 10;

[0024] In this structure, the base 1 can be vertically installed on a designated milling processing device or horizontally installed on a designated milling processing device. The installation position thereof is not limited herein;

[0025] Place the worm workpiece on the base 1. A plurality of driving assemblies can make the bottom rod 5 move. At this time, the side plate 3 can drive the top rod 6 to move, so that a plurality of first clamping blocks 10 can clamp and fix the worm workpiece on the base 1. During this process, the positioning rod 4 will gradually insert into the side seat 2, which can improve the stability of the side plate 3 during movement;

[0026] Before clamping the worm workpiece, rotate the second clamping block 11 according to the height of the worm workpiece. At this time, through the threaded cooperation between the screw rod 12 and the first clamping block 10, the second clamping block 11 can rise to a designated position at the upper end of the first clamping block 10, which is convenient for temporarily adjusting the position of the second clamping block 11, so that the worm workpiece can be more stable during the clamping process and is not likely to shake or move during the processing, and the safety is high.

[0027] In this structure, a second limiting block 15 is fixedly arranged on one side of the bottom of the second clamping block 11, and a first limiting block 13 is fixedly arranged on one side of the top of the first clamping block 10. A limiting rod 14 penetrating through the first limiting block 13 is arranged on the second limiting block 15. After the position of the second clamping block 11 is adjusted, the limiting rod 14 is taken and passed through the second limiting block 15 and the first limiting block 13, so as to limit the second clamping block 11, prevent the second clamping block 11 from rotating above the first clamping block 10, and improve the stability of the second clamping block 11 during use.

[0028] The ejector rod 6 lacks a guiding structure on the side seat 2, which will affect the stability of the ejector rod 6 during movement. A groove 16 is arranged on the ejector rod 6. A vertical rod is fixedly arranged at the upper end of the side seat 2, and a roller 17 is rotatably arranged at the top of the vertical rod. The roller 17 can contact the inner wall of the groove 16. During the movement of the ejector rod 6, the roller 17 will rotate inside the groove 16, providing a guiding structure for the ejector rod 6 on the side seat 2 and improving the stability of the ejector rod 6 during movement.

[0029] Furthermore, two grooves 16 are symmetrically arranged on both sides of the ejector rod 6, and two vertical rods are symmetrically arranged on the upper end of the side seat 2 corresponding to the ejector rod 6.

[0030] Furthermore, an empty groove 9 is arranged on the bottom rod 5. The driving assembly includes a motor 7 and a driving shaft 8. The motor 7 is fixed below the base 1, the driving shaft 8 is fixed at the output end of the motor 7, and the driving shaft 8 is inserted into the empty groove 9. The driving shaft 8 meshes with the inner wall on one side of the empty groove 9. The motor 7 is a servo motor. After the motor 7 is started, the driving shaft 8 can be rotated. At this time, through the meshing effect, the bottom rod 5 can drive the side plate 3 to move, and further the ejector rod 6 can drive the first clamping block 10 to move, making it more convenient for the first clamping block 10 to clamp the worm workpiece.
