Non-contact coaxial alignment method and device suitable for electromagnetic control element

Abstract

The invention discloses a non-contact coaxial alignment method and device suitable for an electromagnetic control element. The method comprises the steps of carrying out the non-contact measurement of an axis offset through a laser displacement sensor based on the cylindrical stator and rotor of a measured electromagnetic control element, enabling the stator and rotor to be installed and fastened through end face threads, using an X-axis linear displacement table and a Z-axis linear displacement table for achieving alignment adjustment of the axes in the two orthogonal directions, and using a rotary table for providing a reference standard for coaxial alignment adjustment. According to the coaxial alignment method, coaxial alignment adjustment before performance testing of an electromagnetic control element product in the manufacturing process can be achieved, compared with an existing tool limiting method, the coaxiality of the stator and the rotor before testing can be improved, and the performance of the electromagnetic control element product can be reflected more truly and accurately, and meanwhile, the product surface is prevented from being scratched. The coaxial alignment method disclosed by the invention can also be used for realizing coaxial alignment adjustment among other circular products.

Description

technical field [0001] The invention relates to a non-contact coaxial alignment method and device suitable for electromagnetic control elements, and belongs to the technical field of coaxial alignment. Background technique [0002] All kinds of electromagnetic control components commonly used in automatic control systems are based on the principle of electromagnetic induction to convert electrical energy into mechanical energy or other kinetic energy. The electromagnetic control components are generally cylindrical in shape and consist of two parts: stator and rotor (or mover). In the process of testing, it is often necessary to carry out various performance tests on it, and there are high requirements for the coaxiality of the stator and rotor during the test. Therefore, it is necessary to adjust the coaxial alignment between the stator and the rotor before the test, so as to improve the test accuracy.

AI Technical Summary

Problems solved by technology

[0003] At present, when adjusting the coaxial alignment of the electromagnetic control components, the stator and the rotor are often fastened and installed by the end thread, and the coaxiality between the two is difficult to detect directly. The traditional method mainly relies on the tooling limit to ensure that the two are coaxial, but Due to the existence of processing tolerances of structural parts, there is inevitably a certain error in the coaxiality, resulting in large test errors, and it is easy to scratch the surface of the product depending on the tooling limit
