[0006] The present invention overcomes that the chuck of the existing lathe usually adopts a traditional structure. When the lathe processes the center hole or end face hole of the workpiece, the workpiece clamped by the existing chuck is prone to axial sliding, resulting in loosening of the workpiece and reducing the machining cost. Accuracy, the shortcoming that affects the quality of the product, the technical problem to be solved by the present invention is to provide a kind of chuck that prevents the workpiece from axially sliding lathe

Abstract
The invention relates to a chuck, in particular to a lathe chuck capable of preventing axial sliding of a workpiece. According to the technical aim, the lathe chuck capable of preventing axial sliding of the workpiece comprises a left rocking handle, a left lead screw, a left nut, a connecting rod III, a sliding block III, a sliding rod III, an upper arc fixed plate, a sliding rod II, a sliding block II, a connecting rod II, a right nut, a right lead screw, a right rocking handle, a connecting rod I, a sliding block I, a sliding rod I, a lower arc fixed plate, a cross rod, a fixed block, a right bearing, a connecting shaft, a left bearing, a sliding block IV, a connecting rod IV and a sliding rod IV. The right lead screw is arranged on the left side of the right rocking handle. According to the lathe chuck capable of preventing axial sliding of the workpiece, by means of the structure of the vertically symmetric arc fixed plates and cooperation of the nuts and the lead screws, the center of the workpiece can be located conveniently.
Description
technical field [0001] The invention relates to a chuck, in particular to a chuck used for preventing workpieces from axially sliding on a lathe. 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 drilling machines. ...
