Abstract

The invention discloses a rapid fixing chuck. The rapid fixing chuck comprises a chuck body, four clamping jaws and a switch, wherein the chuck body is round and is provided with four electric folding rods; the four electric folding rods are symmetrically distributed with the circle center of the chuck body as the center; sliding grooves are formed in the side walls of the electric folding rods; sliding rails are installed on the inner walls of the sliding grooves; connection holes are formed in the electric folding rods; the four clamping jaws are provided with connection rods; the clamping jaws and the connection rods are connected through spring return devices; the connection rods are inserted into the connection holes; springs are installed between the bottom faces of the connection rods and the bottom faces of the connection holes; pulleys are installed on the side faces of the connection rods symmetrically; and the switch is installed on the side face of the chuck body. In this way, the rapid fixing chuck not only can rapidly clamp a workpiece, but also can fix the workpiece firmly, the workpiece does not loose or slide, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a fast fixing chuck. Background technique [0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. The workpiece is clamped and positioned by the jaws distributed on the chuck body. The chuck generally consists of three parts: the chuck body, the movable jaw and the jaw driving mechanism. composition. 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. . [0003] However, there are many problems in the current chuck, such as the inability to quickly and well clamp the workpiece during operation, the workpiece is not firmly clamped, and the workpiece appears loose and slippery. Contents of the invention [0004] T...
