Workpiece internal-external circle concentricity lathe turning tooling and using method thereof

Abstract

The invention discloses a workpiece internal-external circle concentricity lathe turning tooling and a using method thereof; the workpiece internal-external circle concentricity lathe turning tooling is composed of a clamping body, a swelling piece, a baffle palate adjacent to the swelling piece and a set bolt; the clamping body is composed of a machine tool spindle fitting section, a transition section, a workpiece mounting section and a conical section sequentially, the swelling piece is composed of more than three swelling blocks which have the same structure and are provided with clearance respectively and elastic rings arranged on the surface of the external circle of the swelling block, each swelling block is provided with a high-precision inner circular surface adaptive to the conical section of the clamping body and a high-precision external circle ring surface which is adaptive to the inner circle of the workpeice after being swelled, a ring slot for placing the elastic ring is arranged in the middle part of the external circle ring surface of each swelling block, so as to lead the internal-external circle concentricity of the processed workpiece to be in accordance to the precision requirements, improve the processing passing percent and reduces the processing cost.

Description

technical field [0001] The invention relates to a lathe processing tool for coaxiality of inner and outer circles of workpieces and a use method thereof. Background technique [0002] When machining workpieces that require high coaxiality precision of the inner and outer circles on the lathe, it is usually impossible to clamp accurately, resulting in a lower pass rate and higher processing costs. At present, there is no such lathe processing tool for the coaxiality of the inner and outer circles of the workpiece. Its use on the lathe can meet the accuracy requirements of the coaxiality of the inner and outer circles of the processed workpiece, improve the processing pass rate, and reduce the processing cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lathe processing tool for the coaxiality of the inner and outer circles of the workpiece. pass rate, reduce processing costs. [0004] To solve this technic...

Problems solved by technology

[0002] The workpieces that require high coaxiality accuracy of the inner and outer circles are processed on the lathe, usually due to the inaccurate clamping, resulting in a low pass rate and high processing costs.

At present, there is no such lathe processing tool for the coaxiality of the inner and outer circles of the workpiece. Its use on the lathe can meet the precision requirements of the coaxiality of the inner and outer circles of the processed workpiece, improve the processing pass rate, and reduce the processing cost.
