specific Embodiment approach

[0031] Referring to the accompanying drawings, the specific implementation is as follows:

[0032] A method for processing multiple rows of chute grooves on a shaft part, which is used to process multiple rows of chute grooves 8 on the outer circumference of a shaft part 3, and the multi-row chute grooves 8 are uniform along the circumferential direction of the shaft part 3 The chute 8 in the same row is evenly spaced along the axial direction of the shaft part 3. The chute 8 is formed by the cooperation of two sections of side walls 9 and two sections of bottom surfaces. The side walls 9 of the chute 8 are aligned with the shaft The axes of the chute parts 3 are parallel, and the two sections of side walls 9 of the chute 8 are symmetrical about a plane containing the axis of the shaft parts 3, which is the datum plane of the chute 8, and the bottom surface of the chute 8 is perpendicular to the datum plane, and The bottom surfaces of the two sections of the chute 8 are respec...

Abstract

According to the machining method for the multiple rows of inclined grooves in shaft parts. A numerical control boring and milling machine with a rotating table is adopted, the depth size and the angle size of the inclined grooves are guaranteed through auxiliary measurement of a measuring block, a strip-shaped gauge block and a coordinate system of the numerical control boring and milling machine are controlled to rotate synchronously, so that the rotation angles of the shaft parts are corrected through the alignment plane of the strip-shaped gauge block, and the angle size between two adjacent rows of inclined grooves in the circumferential direction of the shaft parts is ensured. According to the method, tools such as the measuring block and the strip-shaped gauge block match with a numerical control boring and milling machine for use, so that various sizes, which are difficult to control, of the multiple rows of inclined grooves on the shaft parts can be measured and corrected, and finally, the machining precision requirement of the multiple rows of inclined grooves on the shaft parts is ensured, the defect that the machining precision of multiple rows of inclined grooves in the shaft parts is difficult to guarantee by a traditional machining method is overcome, and the machining method is integrally simple, reliable, easy to operate, free of special tools, free of pollution, energy-saving, environment-friendly and convenient to apply and popularize.

Description

technical field [0001] The invention relates to the field of chute processing, in particular to a method for processing multiple rows of chute on shaft parts. Background technique [0002] With the development of science and technology and the adjustment of industrial structure, the equipment in various industries is digitized, complicated, and high-precision. The application of shaft parts with multiple rows of chute is more and more extensive. Or the shaft with more than 3 keyways in the same axis direction. The oblique keyway refers to the keyway whose bottom surface is not parallel to the axis. The rigidity of shaft parts is poor, and it is easy to bend and deform during processing. Shaft parts are developing in the direction of high precision, from the previous axial single-row busbar direction keyway to double-row and then to multi-row, from the previous straight keyway to oblique keyway, and the precision has also developed from the previous 7-8 level to The current ...
