Abstract

The invention discloses a hydraulic expansion type chuck for workpiece clamping machining, and belongs to the field of chucks. The hydraulic expansion type chuck comprises a chuck main body, a plurality of uniformly distributed mounting grooves are dug in the inner wall of the chuck main body, a pair of first sliding grooves are dug in the inner walls of the mounting grooves, first sliding blocks are slidably connected into the first sliding grooves, a fixing block is fixedly connected between the pair of first sliding blocks, an arc-shaped clamping plate is fixedly connected to the outer end of the fixing block, clamping grooves are dug in the bottom walls of the mounting grooves, hydraulic rods are mounted in the clamping grooves, a top plate is fixedly connected to the right ends of the hydraulic rods, and the top plate is fixedly connected with the fixing block. A plurality of evenly-distributed working grooves are dug at the upper end of the chuck main body, a workpiece can be better clamped, three jaws still firmly grab the workpiece when power is suddenly off, the workpiece is not prone to flying out of the chuck main body, and therefore the safety of using the chuck main body is effectively improved.

Description

technical field [0001] The invention relates to the field of chucks, in particular to a hydraulic expansion type chuck used for workpiece clamping and processing. Background technique [0002] A chuck is a mechanical device used to clamp a workpiece on a machine tool. A machine tool accessory that clamps and positions workpieces by using the radial movement of movable jaws evenly distributed on the chuck body. The chuck is generally composed of three parts: the chuck body, the movable jaw and the jaw driving mechanism. The minimum diameter of the chuck body is 65mm, and the maximum can reach 1500mm. There is a through hole in the center to pass the workpiece or bar; the back has a cylindrical or short tapered structure, which is connected directly or through the flange to the end of the machine tool spindle. . Chucks are usually installed on lathes, cylindrical grinders and internal grinders, and can also be used with various indexing devices for milling machines and dril...
