Problems solved by technology

[0002] At present, the machine tool clamping devices used in machining workpieces mainly include: rotating spindle and rotating cylinder; there is a pneumatic chuck at the front end of the rotating spindle, and the rotating cylinder is installed at the tail of the rotating spindle of the machine tool. There are pull rods and cylinders on the rotating cylinder. The pneumatic chuck at the front end of the main rotating shaft is connected, and the piston on the rotating cylinder moves to move the pull rod on the rotating cylinder, thereby driving the pneumatic chuck to expand and contract; the workpiece on the chuck is clamped or loosened. Although the clamping device can also realize the automation of workpiece clamping, it needs a huge pneumatic rotary cylinder, which makes the production cost high, the organization production cycle is long, and the assembly process is complicated
