[0002] In the production process of ball screw servo motor, as the core component of accurate feedback motor position and speed information, the correction work of encoder plays a decisive role in ensuring the reliability of motor performance and the high precision of operation. However, reviewing the traditional correction method, the disadvantages are obvious. The traditional fixed mode is extremely tedious and complex, and it is difficult to realize rapid and accurate positioning and installation for different specifications of screw servo motor. For example, when installing small lightweight screw servo motor, a lot of time is spent on adjusting the parameters of the fixing device, and for large heavy load screw servo motor, the fixing process is time-consuming and laborious. This inefficient installation method directly leads to extremely low correction efficiency, which seriously affects the production progress.
