Abstract

The invention discloses a floating clamping jaw for lathe machining. The floating clamping jaw comprises a floating clamping jaw body, a floating clamping jaw base and a floating jaw T-shaped block which are sequentially connected through a floating jaw screw, the floating clamping jaw base and the floating jaw T-shaped block are fixed through a clamping screw, the floating clamping jaw is limited to the floating jaw screw in a rotating mode, the working face of the floating clamping jaw is fixedly provided with a plurality of floating jaw cushion blocks, the floating clamping jaw base is connected with the floating clamping jaw body through a positioning pin, and an elastic deformation body is further arranged between the positioning pin and the floating clamping jaw body in a sleeved mode. By means of the method, parts to be machined through a lathe can be positioned and clamped precisely and reliably, problems of inclined clamping, deformation of part clamping, clamping jaw wear and the like are avoided and clamping accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of bearing turning, in particular to a floating jaw for turning. Background technique [0002] Usually, in various types of lathes, the clamping and positioning device used is a three-jaw chuck. The ordinary three-jaw chuck does not position the axial direction of the part when machining the inner hole of the part, which may cause clamping The axis of the holding part and the axis of the three-jaw chuck are skewed (clamping). [0003] In addition, the three-jaw chuck has been used for a long time. With the wear of the jaws, the center of the three-jaw will deviate from the center of the main shaft of the lathe, which will increase the shape and position tolerance of the processed parts. [0004] Especially when processing thin-walled parts, the three-jaw chuck can only be in three-point contact with the part. Even a slight clamping force will cause the part to produce "round edges". "It's also hard to fix....
