Lathe chuck for preventing workpiece from axially sliding

Abstract

The invention relates to a chuck, in particular to a lathe chuck for preventing a workpiece from axially sliding. The technical purpose of the invention is to provide the lathe chuck for preventing a workpiece from axially sliding. In order to realize the technical purpose, the lathe chuck for preventing a workpiece from axially sliding is provided and comprises a guide rod IV, a nut IV, a fan-shaped fixing plate IV, a fan-shaped fixing block IV, a nut III, a guide rod III, a fan-shaped fixing block III, a fan-shaped fixing plate III, a nut II, a guide rod II, a fan-shaped fixing plate II, a fan-shaped fixing block II, a guide rod I, a nut I, a fan-shaped fixing plate I, a fan-shaped fixing block I, a disc-shaped electromagnet and a connecting shaft. The guide rod I is arranged on the right side of the disc-shaped electromagnet. The lathe chuck, provided by the invention, for preventing a workpiece from axially sliding is simple and novel in structure, reasonable in design, good in workpiece fixing effect, high in workpiece machining precision and capable of preventing a workpiece from axially sliding during workpiece machining.

Description

technical field [0001] The invention relates to a chuck, in particular to a chuck for lathes which prevents workpieces from sliding axially. Background technique [0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It is a machine tool accessory that uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. 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 ma...

Problems solved by technology

[0004] The chuck of the existing lathe usually adopts the traditional structure. When the lathe processes the center hole or the end face of the workpiece, the workpiece held by the existing chuck is prone to axial sliding, resulting in loosening of the workpiece, reducing the processing accuracy and affecting the product. quality, and even lead to batch scrapping of products, causing huge economic losses to the enterprise
