Abstract

The invention relates to a rapid fixture special for eccentric adjustment of a rotary encoder circular grating. The rapid fixture comprises a fixing plate, a clamping plate, a hook-shaped screw, a tension spring, a bolt type cam follower needle roller bearing, a shifting lever cam, an outer thread pin, a step pin and a cylindrical compression spring. In the rapid fixture special for eccentric adjustment of the rotary encoder circular grating, a four-point positioning way is adopted, and the clamping and positioning of an encoder are realized by using the extension and retraction characteristics of the tension spring, the rotation characteristic of a cam mechanism, a lever principle and the like; the rapid fixture special for eccentric adjustment of the rotary encoder circular grating has a simple and reasonable structure, and is convenient and rapid to use; by adopting the rapid fixture, rapid clamping of the rotary encoder is realized, and the efficiency in eccentric adjustment of the rotary encoder circular grating on a production line is increased.

Description

technical field [0001] The invention relates to a special quick-change fixture for adjusting the eccentricity of a circular grating of a rotary encoder, which belongs to the field of mechanical fixtures and is specifically used for fast clamping of an encoder during the eccentric adjustment process of a circular grating of a rotary encoder. Background technique [0002] With the rapid development of measurement and control technology, photoelectric encoders are used in many fields. In the production process of encoders, the actual rotation center of the circular grating and the rotation center of the encoder spindle are difficult to coincide, and there is a certain coaxiality error. Therefore, it is necessary to Adjust the coaxiality of the circular grating, minimize the coaxiality error, and realize the accuracy of the encoder output signal. Therefore, the assembly of the grating and the encoder spindle is an important link in the production and manufacture of the photoelect...
