Rotating joint extension shaft and motor connection

There is a special type of extension shaft rotary joint in the rotary joint, which adopts an extension design. Both the standard MFQ series rotary joint and the SE series compact rotary joint can be extended into the extension shaft rotary joint series. The most common extension shaft rotary joint is mainly connected to the motor spindle and three grip chuck, and needs to withstand a certain weight and downward tension. There are high-speed and ordinary types to choose from. Extension shaft type rotary joints belong to non-standard rotary joints and are commonly used in pneumatic environments

The common specifications for the extension shaft of a rotary joint are 8 * 20, 10 * 20, 12 * 20, 14 * 20, and 16 * 20. In order to achieve better alignment, the extension shaft of the rotary joint is connected to the main shaft of the motor through a flexible coupling, which allows for better use in different concentric environments. The other section of the rotary shaft is connected to a pneumatic three grip connection, and the rotary joint is equipped with a pneumatic rotation transition device in the middle. At the same time, a 360 ° ventilation device is used to provide clamping and releasing effects for the three grips. The main focus is on a 2-channel pneumatic rotary joint, which controls one cylinder
