Problems solved by technology

[0003] At present, the ordinary rotary encoder, its shaft is connected with the shaft coupling or the sleeve is connected with the detection shaft, the auxiliary installation space is large, and the encoder is easy to loosen, thus affecting the accuracy and stability of the encoder.
In addition, in the process of use, the encoder itself is worn out after a long period of vibration, which will affect the working life of the encoder; in addition, the encoder is currently transmitted to the control terminal through a cable for signal processing
Factors such as electromagnetic interference in the transmission process have affected the signal accuracy synchronization, etc., and the signal cannot be recognized and the signal is lost.

A circuit board is further arranged in the shell, one end of the circuit board is connected with the bottom of the main body through the copper column, and the optocoupler is fixedly connected with the circuit board; one end of the cable is movably connected with the shell through the waterproof tightening cover; and the gratingmeter is arranged on the surface of the shell.

Description

technical field [0001] The invention relates to the field of sensor encoders, in particular to a grating encoder with a built-in solid shaft. Background technique [0002] Rotary encoders are used to measure the rotational movement of a rotatably mounted object, in particular a shaft, over one or more revolutions. Here, the rotational movement is acquired incrementally (inkremental) or absolutely. In combination with a rack and pinion or with a lead screw, rotary encoders can also be used to measure linear movements. [0003] At present, the common rotary encoders, whose shafts are connected by couplings or sleeves to the detection shafts, have a large auxiliary installation space and are easy to loosen the encoders, thereby affecting the accuracy and stability of the encoders. In addition, during use, the long-term vibration will also cause wear to the encoder itself, which will affect the working life of the encoder; in addition, the encoder is currently transmitted to t...
