Problems solved by technology

[0004] In the prior art, the accuracy of curved surface grooves depends on the accuracy of 3D modeling, and the process of 3D modeling is complicated. Any error during modeling may cause the curved surface grooves to fail to meet the requirements of providing motion guidance for cylindrical parts, making the curved surface grooves Processing is very inconvenient

Abstract

The invention discloses a curved surface groove machining method and belongs to the technical field of mechanical machining. The machining method comprises the steps that a center line of a curved surface groove is determined on the outer wall of an annular workpiece; pre-drilling holes are drilled in a starting point and an ending point of the center line of the curved surface groove correspondingly; machining is performed from the pre-drilling hole of the starting point to the pre-drilling hole of the ending point along the center line so as to form an initial curved surface groove; and machining is performed on the initial curved surface groove so as to obtain the curved surface groove. According to the curved surface groove machining method, no complete three-dimensional modelling needs to be performed on the annular workpiece, the technical preparation and machining process is simple, and in addition, the curved surface groove accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing curved surface grooves. Background technique [0002] During machining, it is necessary to process curved surface grooves on the outer wall of the annular workpiece. The surface groove is a bar-shaped space surface groove with constant groove width and rounded starting and ending points. The function of the curved surface groove is to provide motion guidance for cylindrical parts. The center is always kept horizontal and has a certain gap with the side wall of the curved groove. At present, when processing this type of curved surface groove, the space model of the annular workpiece and the curved surface groove is usually established in the 3D software. In order to ensure that the cylindrical parts meet the conditions of keeping level and maintaining a certain gap with the side wall of the curved surface groove when moving in the curved sur...
