Problems solved by technology

[0002] The structure of thin-walled parts generally has relatively strict wall thickness and coaxiality requirements. The traditional processing process is: three-jaw clamping flat end surface, inner hole-inner hole clamping outer cylindrical surface-turning clamping flat end surface, Due to the thin wall thickness and poor rigidity of this type of parts, it is difficult to clamp, takes a long time, and is prone to deformation during processing, resulting in the inability to guarantee the inner and outer circle dimensions and coaxiality requirements
As a result, the processing efficiency of this type of product is low and the product failure rate is high

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] A lathing clamping and processing method of thin-walled and weakly rigid parts of the present invention includes the following content: clamping the parts with a tooling.

[0023] Tooling comprises tire expansion 4, expansion bolt 5.

[0024] The upper part of the tire inside has a tapered hole as a blind hole, and the center of the tapered hole has a threaded through hole; the upper side of the tire is cut and processed with 6 radial grooves with a width of 0.5 units, located at 6 symmetrical places on the circumference, and the expansion bolts 2 It includes an end face, a nut and a threaded segment from top to bottom; the outside of the nut is a circular table (conical arc surface), which is the same size as the tapered hole inside the bulging tire. When the expansion nut is screwed into the tapered hole inside the tire expansion, as the outer surfa...

Abstract

The invention provides a clamping and machining method for turning of a thin-wall weak-rigidity part and belongs to the technical field of the machining process. The clamping and machining method is suitable for a lathe clamping tool for the thin-wall weak-rigidity part. The lathe clamping tool for the thin-wall weak-rigidity part comprises an expansion jig and an expansion bolt. According to themethod, the clamping tool is used for clamping the part. Through the clamping tool, the defects existing in the clamping and machining method of the existing process are overcome, the efficiency of alathe machining the thin-wall part can be improved, and the unqualified rate of products can be reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing technology, and relates to a lathe processing clamping and processing method of special parts. Background technique [0002] The structure of thin-walled parts generally has relatively strict wall thickness and coaxiality requirements. The traditional processing process is: three-jaw clamping flat end surface, inner hole-inner hole clamping outer cylindrical surface-turning clamping flat end surface, Due to the thin wall thickness and poor rigidity of this type of parts, it is difficult to clamp, takes a long time, and is prone to deformation during processing, resulting in the inability to guarantee the inner and outer circle dimensions and coaxiality requirements. As a result, the processing efficiency of this type of product is low and the product failure rate is high. Contents of the invention [0003] The object of the present invention is to provide a lathe clamping and proc...
