Description

Technical Field

[0001] This utility model relates to the field of molecular pump dynamic balancing machining technology, specifically to a molecular pump dynamic balancing cutting and milling composite machining equipment. Background Technology

[0002] Molecular pump dynamic balancing is a key technology that corrects imbalances in rotating components such as rotors to reduce vibration and noise and improve efficiency. Its core is to measure and adjust the rotor's mass distribution to ensure dynamic balance during high-speed operation. Molecular pumps rely on high-speed rotating blades to accelerate and compress gas molecules. Uneven mass distribution in the rotor can lead to severe vibration, accelerated bearing wear, and even system failure. Molecular pump dynamic balancing involves machining the rotor blank using ultra-precision turning and milling techniques to shape the impellers, journals, and other features of the rotor, ensuring that dimensions, roundness, cylindricity, and coaxiality reach micron-level or even sub-micron-level precision. To improve the efficiency of molecular pump dynamic balancing machining, a composite machining equipment is needed; however, existing composite machining equipment still has the following shortcomings: When using existing composite processing equipment, most of these machines are not suitable for quickly adjusting the clamping components to fit the size of the rotor blank. Furthermore, the clamping components are not easily adjustable in terms of angle, leading to decreased positioning accuracy, reduced processing efficiency, increased production costs, and higher scrap rates. This results in a decline in the practicality and efficiency of the composite processing equipment. Utility Model Content

A torque motor 402 is installed on the outer end of the mounting frame 401, and the front end of the torque motor 402 is connected to the movable frame 403. A stepper motor 404 is installed at the lower middle of the movable frame 403. A limiting disk 405 is connected to the front end of the stepper motor 404. A limiting groove 406 is formed inside the limiting disk 405, and a limiting slider 407 is connected inside the limiting groove 406.

The torque motor 402 is fixedly mounted on one end of the mounting frame 401 by fastening bolts. The output shaft of the torque motor 402 is connected to the movable frame 403 via a coupling. The operation of the torque motor 402 drives the movable frame 403 to rotate inside the mounting frame 401. The operation of the stepper motor 404 at the lower end of the movable frame 403 drives the limiting plate 405 to move on the movable frame 403. When the end rotates, the internal dimensions of the limiting groove 406 inside the limiting disk 405 are adapted to the external dimensions of the limiting slider 407 installed at the lower end of the movable block 408. Thus, the movable block 408 moves back and forth through the limiting groove 406 and the limiting slider 407. The mounting slider 410 installed at the lower end of the movable block 408 is sleeved on the outside of the limiting base 411. The mounting slider 410 and the limiting base 411 increase the stability of the movable block 408 during movement. The movement of the movable block 408 drives the clamping part 409 to contract and expand, thereby limiting and fixing the rotor blank to be processed, improving the overall practicality and efficiency of the composite processing equipment.

The movable slider 505 is limited by the limiting rod 506, so that the movable slider 505 slides up and down inside the receiving frame 502, thereby driving the fixed block 507 to adjust its position. The servo motor 508 installed on the lower right side of the fixed block 507 drives the pulley 509 to rotate, which causes the transmission belt 510 to rotate, and drives the milling part 511 installed on the lower left side of the fixed block 507 to rotate, thereby performing a composite machining operation of cutting and milling on the rotor blank to be processed, improving the overall practicality and efficiency of the composite machining equipment.

Then, the drive motor 503 drives the lead screw 504 to rotate, causing the movable slider 505 connected to the lead screw 504 to rotate accordingly. The limit rod 506 limits the movable slider 505, causing it to slide up and down inside the receiving frame 502. This causes the fixed block 507 to adjust its position. The servo motor 508 installed on the lower right side of the fixed block 507 drives the pulley 509 to rotate, causing the transmission belt 510 to rotate. This, in turn, drives the milling part 511 installed on the lower left side of the fixed block 507 to rotate, thereby performing a composite machining operation of cutting and milling on the rotor blank to be processed, improving the overall practicality and efficiency of the composite machining equipment.
