Machining tool and machining method for controlling coaxiality and parallelism of parts

Abstract

The invention provides a machining tool and a machining method for controlling the coaxiality and parallelism of parts. The machining tool comprises a turning tool rod and a machining blade, wherein the turning tool rod is shaped like an L, and comprises a turning tool rod clamping part and a turning tool rod machining part, and the machining blade is connected with one end, which is opposite to the turning tool rod clamping part on the turning tool rod, of the turning tool rod. The machining method for controlling the coaxiality and parallelism of the parts includes the following steps that firstly, the machining tool is chosen, and the machining tool and the part to be machined are mounted on a machine tool; secondly, a conventional turning tool is utilized to machine the front end surface and a bore of the part to be machined; finally, the tool is replaced, the feed direction of the turning tool rod is adjusted, and the rear end surface or excircle of the part to be machined is machined. The invention can be utilized to better control the parallelism between the front end surface and rear end surface of the part to be machined and the coaxiality between the excircle and bore of the part to be machined, the efficiency of machining is increased, and the cost of machining is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical parts machining, in particular to a processing tool and a processing method for controlling the coaxiality and parallelism of parts. Background technique [0002] In the machining process of mechanical parts, it is often necessary to process the front and rear end faces of the parts, as well as the outer circle and inner hole. Due to the parallelism between the front and rear end faces and the coaxiality between the inner hole and the outer circle of the mechanical parts after processing, the processing quality of the parts itself is greatly affected, which seriously affects the product qualification rate of the processed parts, resulting in the production cost of the parts. rise. [0003] In order to ensure that the parallelism between the front and rear end faces and the coaxiality between the inner hole and the outer circle are controlled within the acceptable range after the part is proces...

AI Technical Summary

Problems solved by technology

Using the above-mentioned sub-process processing method makes the processing of the front and rear end faces, the inner hole and the outer circle of the parts to be processed completely separate, requiring the use of two machine tools, resulting in higher processing costs for the parts, and changing the machine tool for processing also requires The parts are re-clamped and positioned, so the machining efficiency of the parts is greatly reduced; moreover, due to the positioning error of the inner expansion tool, it also leads to the same gap between the inner hole and the outer circle of the processed part. The axiality is not easy to control, which affects the pass rate of the overall processing of parts
