[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figs. 1-3 This utility model provides a fixture for processing vacuum equipment parts, including a base plate 1, a cylinder 2 fixedly connected inside the base plate 1, a fixed plate 17 fixedly connected to the top of the cylinder 2, a rotating shaft 3 rotatably connected inside the fixed plate 17, a working plate 4 fixedly connected to the top of the rotating shaft 3, an inner groove 5 is formed around the inside of the working plate 4, a clamping plate 7 for clamping vacuum equipment parts is slidably connected to the inner side of the inner groove 5, several support legs are fixedly connected to the outer side of the bottom of the base plate 1, a limit rod 16 is fixedly connected to the end of the fixed plate 17 away from the cylinder 2 and is slidably connected inside the base plate 1, a motor 15 is fixedly connected to the bottom of the fixed plate 17 and its output end is fixedly connected to the rotating shaft 3, and there are four clamping plates 7, which are distributed in a ring outside the rotating shaft 3.

[0024] When cylinder 2 is activated, it pushes the fixed plate 17 and the working plate 4 to a suitable height. Then, motor 15 is activated, which drives the rotating shaft 3 and the working plate 4 to rotate to a suitable angle.

[0025] Please see Figs. 1-3 A strong spring 9 is fixedly connected to one end of the inner groove 5. One end of the strong spring 9 is fixedly connected to the clamping plate 7. A slide block 10 is slidably connected to the outer side of the rotating shaft 3. Rotating rods 11 are rotatably connected to all four sides of the slide block 10. The top end of the rotating rod 11 is rotatably connected to the corresponding clamping plate 7. A connecting block 12 is fixedly connected to the bottom of the slide block 10. A rotating frame 14 is fixedly connected to the bottom of the working plate 4. A drive rod 13 is rotatably connected to the outer side of the rotating frame 14. One end of the drive rod 13 is rotatably connected to the connecting block 12. The moving rod 13 is located at the end of the rotating frame 14 near the connecting block 12, which is much shorter than the end away from the connecting block 12. The working plate 4 has an outer groove 6 on both sides of each inner groove 5. The two ends of the bottom of the clamping plate 7 are slidably connected to the inside of the outer groove 6. The inner rod 8 is fixedly connected inside the inner groove 5. The clamping plate 7 is slidably connected to the outside of the inner rod 8. The strong spring 9 is located on the outside of the inner rod 8. The strong spring 9 is located at the end of the clamping plate 7 near the rotating shaft 3. The rotating frame 14 is located at the bottom of the working plate 4 near the connecting block 12.

[0026] Press down on the drive rod 13 to make it rotate around the rotating frame 14. Push the slide block 10 upward through the connecting block 12. Through the rotating rod 11, make the clamping plate 7 slide outward in the inner groove 5 and pull open the strong spring 9. Place the vacuum equipment accessory on the inner side of the clamping plate 7 on the working plate 4. Release the drive rod 13, the strong spring 9 retracts, and drive the clamping plate 7 to move inward, clamping the accessory and processing it.

[0027] When clamping parts is required, the operator only needs to apply a driving force to the slide 10. This force will be evenly transmitted to each clamping plate 7 through the rotating rod 11. It also ensures that the four clamping plates 7 move outward at the same speed and force. The inner rod 8 inside the inner groove 5 further enhances the stability of the clamping plates 7, preventing them from shaking or deviating from the predetermined track during movement. This makes the device not only more convenient to operate, but also significantly improves the clamping stability of the parts.

[0028] When the drive rod 13 pushes the slide 10 and clamp 7 to move, the powerful spring 9 is compressed and stores energy. Once the external force disappears, the spring will quickly release the stored energy, pushing the clamp 7 back to its original position with a strong rebound force, thereby ensuring stable clamping of vacuum equipment accessories. The rotating frame 14, as a support structure, cleverly divides the drive rod 13 into two sides of unequal lengths. By cleverly utilizing the lever principle, a larger clamping effect can be achieved with a smaller operating force, which not only improves the practicality of the device but also significantly improves the ease of operation.

[0029] The working principle and usage process of this utility model are as follows: Cylinder 2 is started, pushing the fixed plate 17 and the working plate 4 to a suitable height. Motor 15 is started, driving the rotating shaft 3 and the working plate 4 to rotate to a suitable angle. The drive rod 13 is pressed down, causing it to rotate around the rotating frame 14. The sliding block 10 is pushed upward through the connecting block 12. Through the rotating rod 11, the clamping plate 7 slides outward in the inner groove 5 and pulls open the strong spring 9. The vacuum equipment accessories are placed on the inner side of the clamping plate 7 on the working plate 4. The drive rod 13 is released, the strong spring 9 retracts, and the clamping plate 7 moves inward to clamp the accessories for processing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
