[0002] A chuck is a mechanical device used to clamp a workpiece on a machine tool. It is a machine tool accessory that clamps and positions a workpiece by radially moving the movable jaws evenly distributed on the chuck body. A chuck generally consists of three parts: a chuck body, movable jaws, and a jaw drive mechanism. A hydraulic chuck is a fixture controlled by a hydraulic system, used to clamp a workpiece on the spindle of a CNC lathe.
[0003] For example, a composite hydraulic chuck with patent application number CN202022303876.7 includes a protective device, a clamping device, a telescopic device, a buffer device and an oil inlet device. The protective device includes a protective shell and a chassis. The protective shell is a cylindrical tubular structure, and the chassis is a cylinder with a cavity inside. The clamping device includes a mounting block and a rocker. The outer surfaces of several mounting blocks are connected to the inner surface of the protective shell. The telescopic device includes a telescopic rod, and the outer surface of the telescopic rod is connected to one end of the rocker. The buffer device includes a buffer cylinder, a buffer gasket and a sleeve. The utility model discloses a composite hydraulic chuck. By providing a buffer cylinder, the wear of the hydraulic cylinder can be reduced to achieve the purpose of protecting the hydraulic cylinder. By providing a buffer gasket, the axial impact can be reduced when the chuck cooperates with the machine tool. By providing a telescopic rod, the hydraulic cylinder is used to drive the telescopic rod to move back and forth to achieve the purpose of controlling the claws.
