Example of Use of Shaft Collars
■Mechanism name of Shaft Collars
Manipulator capable of horizontally adsorbing and conveying special-shaped workpieces
■Mechanism function of Shaft Collars
1. Through the suction cup, it is not necessary to disassemble and convey resin shells of different heights.
2. Through the guide rail, the suction cup can slide to absorb the special-shaped workpiece.
3. After the slider is fixed by clamp, the state of the special-shaped workpiece can be maintained.
■Function of Shaft Collars
1. Fixed to one end of the ball guide shaft, it can be used as a simple stopper to prevent the ball guide shaft from sliding out.
2. According to the shape of the workpiece, the position of the shaft collar on the shaft can be adjusted at any time to control the sliding stroke of the ball guide shaft.
