Abstract

The invention discloses a uniformly-stressing tightening device. The tightening device comprises a lathe headstock, a rotating shaft, a cross beam, a chuck, a tightening device body, winch inserting holes and a control system. The rotating shaft is arranged at the front part of the lathe headstock. The cross beam is arranged above the lathe headstock. The chuck is mounted on the rotating shaft. The tightening device body is arranged below the front end of the cross beam. The four wrench inserting holes are uniformly formed in the outer wall of the chuck in a spaced manner. The rotating shaft and the tightening device body are separately connected with the control system. The tightening device body comprises an electric wrench, a lifting motor, a lifting rod, a groove and a straight hexagon wrench. One end of the electric wrench is connected to the cross beam. Through adoption of the tightening device, the degrees of tightness of clamping jaws in fixing can be the same, the turning effect is good, time and labor are saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a machine tool, in particular to a uniformly stressed elastic device. 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. [0003] When the existing ch...
