Lathe fixture for inner hole processing of screw sleeve parts

Abstract

The invention discloses a screw sleeve part inner hole processing lathe clamp, which comprises a clamp body, a screw nut, a cone sleeve and a reset spring, wherein a clamp body positioned by a notch is arranged on a lathe main shaft through a transition disc, the front end of the clamp body is a barrel-shaped thin wall with the external taper, in addition, the outer diameter of the back end of the thin wall is greater than the outer diameter of the front end, the inner diameter of the thin wall is matched with the outer diameter of a screw sleeve to be processed, the cone sleeve with the internal taper matched with the external taper of the thin wall is arranged on the outer side of the thin wall in a sleeving way, the reset spring is arranged at the thin wall part in a sleeving way and is positioned between a cone sleeve and a threaded step positioned at the back part of the clamp body, and the screw nut passes through the thin wall and the cone sleeve and is connected with the clamp body through screw threads. The screw sleeve part inner hole processing lathe clamp has the advantages that the structure is compact, the operation is simple, convenient and reliable, the positioning precision is very high, the processing quality can be easily ensured, and higher practicability is realized.

Description

technical field [0001] The invention relates to a lathe fixture, in particular to a lathe fixture for turning inner holes at both ends of a screw sleeve part. Background technique [0002] When processing the inner holes at both ends of the screw sleeve parts, a three-jaw chuck is usually used to position and clamp the workpiece through the outer circle of the workpiece. The three-jaw chuck has the advantages of strong versatility, no need for special manufacturing, and high centering accuracy. However, when the three-jaw chuck is used to clamp the workpiece, because of its small contact area with the workpiece, the The clamping force is large, especially when the wall thickness of the workpiece is thin, the workpiece is more likely to be clamped and deformed, which makes it difficult to guarantee the processing quality of the workpiece. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the purpose of the present invention is ...
