Constant-turning-quantity turning lathe for steel skeleton plastic composite pipe

Abstract

The invention provides a constant-turning-quantity turning lathe for a steel skeleton plastic composite pipe. The constant-turning-quantity turning lathe comprises a lathe body, fixtures which are arranged on the lathe body and used for clamping the composite pipe and a turning assembly arranged on a lathe cutterhead, and the fixtures can drive the composite pipe to do linear feeding motion; and the turning assembly comprises a turning cutter arranged in the mode of corresponding to the outer wall of the composite pipe, the turning cutter is configured to be capable of doing reciprocating motion in the radial direction of the lathe cutterhead along with changes of the outer wall of the composite pipe so as to be always compressed on the outer wall of the composite pipe, and a turning quantity determining portion is arranged on a turning cutter blade. According to the constant-turning-quantity turning lathe for the steel skeleton plastic composite pipe, the turning cutter is arranged tobe capable of doing reciprocating motion in the radial direction of the lathe cutterhead so as to keep a compressed state on the outer wall of the composite pipe, therefore, the turning cutter can conduct turning by taking the outer wall of the composite pipe as the standard all the time in the turning process, it can be guaranteed that the wall thickness of the turned composite pipe outer wall is always uniform, and the turning effect of the composite pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a turning lathe with a fixed turning amount for a steel frame plastic composite pipe. Background technique [0002] The last processing procedure of the steel skeleton plastic composite pipe product is turning. It is necessary to turn the outer wall of the outer wall with a length of about 200mm to remove the outer skin with a thickness of about 1mm, so that the circumference of the outer wall of the end of the steel skeleton plastic composite pipe can reach a certain dimensional accuracy, so that It can cooperate with the electrofusion sleeve when the composite pipe is connected. At present, when the steel skeleton plastic composite pipe is turned, due to the deviation of the outer circumference of the steel skeleton plastic composite pipe, the ellipse of the pipe, and the poor clamping accuracy of the fixture, etc., the latitude line is often exposed during turnin...

AI Technical Summary

Problems solved by technology

At present, when the steel skeleton plastic composite pipe is turned, due to the deviation of the outer circumference of the steel skeleton plastic composite pipe, the ellipse of the pipe, and the poor clamping accuracy of the fixture, etc., the latitude line is often exposed during turning of the steel skeleton composite pipe and after turning. The problem of uneven wall thickness causes quality problems of composite pipe products and affects the qualification rate and production efficiency of composite pipes
