Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples.

[0021] A production process flow of an automobile steering tie rod joint assembly disclosed by the present invention comprises the following steps:

[0022] 1. Prepare raw materials for the production of joints and ball studs;

[0023] 2. Carry out turning, milling and planing pliers processing of raw materials to obtain rough blanks of joints and ball studs;

[0024] 3. Heat treatment of the rough billet;

[0025] 4. Grinding the rough billets after heat treatment; using a high-precision CNC spherical lathe, the ball pins are positioned directly and automatically clamped on the high-precision spindle with a tapered surface, and then the hydraulic system is used to automatically work in a cycle with CNC commands, eliminating artificial Unstable factors, coupled with the micro-adjustment device of high-precision ball screw, seem to control the feed accuracy within 0.0...

Abstract

The invention relates to the field of automotive parts, and specifically relates to a production process flow of an automotive steering linkage joint assembly. The process flow comprises the steps that: 1.1, raw materials used for producing a joint and a ball pin are prepared; 1.2, the raw materials are subjected to processes such as machining, milling, planning, and clamping, such that rough blanks of the joint and the ball pin are obtained; 1.3, the rough blanks are subjected to a heat treatment; 1.4, the treated rough blanks are subjected to abrasive machining; 1.5, ultrasonic flaw detection is carried out; 1.6, the joint and the ball pin obtained after processing and flaw detection are tested; and 1.7, a finished product is assembled by using the joint, the ball pin, and other automotive steering linkage joint assembly parts. With the process flow provided by the invention, working efficiency is greatly improved, and qualities of the joint and the ball pin are greatly improved.

Description

[0001] technical field [0002] The invention relates to the field of automobile parts, in particular to a production process flow of an automobile steering rod joint assembly. [0003] Background technique [0004] The car steering tie rod joint assembly is located in the car steering system, between the steering gear and the steering knuckle arm, moves up and down with the tires, and transmits the steering force of the steering wheel to the tires through the transmission and swing of the joints. During the use of the car, loose frames often appear between the joint and the spherical shell due to wear and tear. This situation will affect the stability of the car in the slightest, and will cause the vehicle to malfunction and cause serious accidents. [0005] The joints and ball studs play a decisive role in the quality of the automotive steering tie rod joint assembly. [0006] Therefore, the present inventor made further research on this, and developed a production p...
