Embodiment Construction

[0013] Accompanying drawing has provided the structural representation of the present invention. If two rectangular concave teeth that are X-shaped are processed on the end face of a workpiece 3, according to the process method of the present invention, a L6120 broaching machine 1 is reformed, and a set of design and manufacture has the ability to position and guide the broach, and to make the broach The fixture 4 with clamping device for dual positioning of the workpiece is fixed on the broaching machine 1, and a set of single-side cutting rectangular broach 2 is designed and manufactured. Fix the jig 4 on the broaching machine 1, the broach 2 is installed in the clamp body of the jig 4, and its head is installed on the chuck of the broaching machine 1. When working, retract the guide neck part of the broach 2 to the position of the workpiece 3, the edge of the broach 2 faces upwards, and the cut part of the workpiece 3 faces downwards, after positioning and clamping the work...

Abstract

A technology for machining the contrate tooth profile by broaching includes such steps as designing a workpiece fixture and a broaching tool with its shape matched with the said contrate tooth profile, fixing the fixture to a broadching machine, installing the broadching tool to the guide slot of fixture, fixing the workpiece to the fixture, and broaching. Its advantages are high efficiency and precision, and high reliability.

Description

(1) Technical field [0001] The invention relates to a processing method for end tooth profile. (2) Background technology [0002] In the mechanical structure using end face tooth profile positioning, the processing method of end face tooth profile is basically single-tooth milling, integral milling or wire cutting. These processing methods have low efficiency, poor tooth profile accuracy, and low surface roughness. Moreover, it is unstable, and the centering accuracy of the tooth profile is low. (3) Contents of the invention [0003] Aiming at the shortcomings of the existing end face tooth profile processing methods, the invention provides an end face tooth profile processing process with high efficiency, high precision and stable and reliable quality. [0004] The processing technology of end face tooth profile of the present invention comprises the following steps: [0005] (1) Design a set of fixtures for workpiece clamping and positioning and a set of broaches that ...
