Clamping Screws Example of Use
Angle adjustment mechanism using Clamping Screws and steel balls
Mechanism function:
Put the resin case in the inspection position, and check whether the resin case hole is normal through a photoelectric sensor.
The function of the Clamping Screws:
Through the change of the up and down position of the clamping screw, it plays the role of micro-adjusting the emission angle of the photoelectric sensor.
