Embodiment Construction
[0007] The present invention is described in detail below by accompanying drawing and specific embodiment:
[0008] As shown in the figure, this process is completed by four steps: pre-turning large holes, straightening spline holes, rough extrusion, and fine extrusion. Use a spline broach to pull out the spline groove of the straight hole, then use a rough extrusion knife to extrude the spline hole to form a certain taper, and then use a fine extrusion knife to extrude the spline to the required size, thereby reducing tool wear and improving transfer accuracy.

Description
technical field [0001] The invention relates to the technical field of mechanical processing technology, in particular to a processing technology for a spline hole of a steering arm. Background technique [0002] The current machining process of the spline hole of the steering arm adopts one-time fine extrusion forming, which leads to an increase in the durability of the tool and the surface roughness of the processed workpiece. already larger than the theoretical size. During assembly, the tooth top contact is formed between the steering arm and the steering shaft, and a gap is generated on the tooth side, resulting in a loose connection and affecting product quality. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a process for machining the spline hole of the steering arm. [0004] In order to achieve the above object, the technical solution adopted by the present invention is to complete by four steps ...
