[0029] In this application, an innovative automatic shaft pressing device is designed for the steel shaft assembly scenario of the actuator, which realizes the operation of automatically feeding the small steel shaft and accurately inserting it into the set position inside the actuator housing. Reliable press-fit fixation is achieved through mechanical force, replacing the traditional cumbersome and time-consuming manual adjustment method, thereby significantly improving the safety and accuracy of the operation, greatly improving the overall efficiency of the production line, reducing human resource investment and improving the consistency of product batch quality.

[0030] According to an example of the present invention, a first linear slide assembly 5 is installed on the frame 1, and the support platform 2 is fixed on the first linear slide assembly 5 to reciprocate linearly toward the front end of the frame 1. The support platform 2 is provided with a shell clamping groove 6 for clamping the actuator shell 4.

[0031] According to an example of the present invention, a sensor fixing seat 7 is provided on the support platform 2, and a lower fixing hole 8 is installed on the sensor fixing seat 7. The lower fixing hole 8 is used to install a lower optical fiber position sensor. The lower optical fiber position sensor is horizontally opposite to the upper part of the shell slot 6 and is used to sense the placement status of the actuator shell 4.
