Problems solved by technology
[0003] At present, for the existing shift forks of automobiles, although the overall structure of the cast iron shift fork is relatively strong, it needs to be processed on the combined machine tool whether it is hole forming or grinding, and the overall weight is relatively heavy. Installation and positioning conversion are very troublesome, and although the light-weight cast aluminum shift fork is strengthened by setting ribs at the corners, due to the relatively complicated structure, it is difficult to complete the comprehensive polishing of the multi-position surface, and the overall strength still needs to be strengthened

Embodiment Construction
[0026] In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.
[0027] like Figure 1 to Figure 5 As shown, an automobile shift fork processing technology includes the following steps:
[0028] S1. Selection of raw materials: use cast steel split blanks and cast aluminum fork blanks;
[0029] S2, making the fork body 1: turning the end face of the split blank to make the fork body 1;
[0030] S3. Make the fork foot 2: correct the fork foot blank and rough mill its two ends and inner side to make the fork foot 2;
[0031] S4. Grinding and deburring: Deburring the shifting fork body 1 and the shifting fork foot 2 respectively, so that the inside and edge of the shifting shaft hole on the shifting fork body 1 are smooth, and the surface of the shifting end of the shifting fork foot 2 is smooth;
...

The invention discloses a processing technology for a shift fork of an automobile, which relates to the technical field of production methods for mechanical parts. test. The present invention adopts the fork body and the fork legs of different materials, and is a new type of fork product made by the split assembly method. At the same time, it cooperates with the assembly end surface position between the fork body and the fork foot, which greatly offsets the torsional torque of the half-threaded stud and the chuck during the rotation of the fork, thereby ensuring the overall structural strength of the fork, that is, the The weight reduction of the fork can be achieved under the premise of ensuring the structural strength; by setting the positioning mechanism and the rotating clamping mechanism on the frame, the automatic assembly of the fork body and the fork legs can be realized under the driving of the cylinder and the driving motor.
Description
technical field [0001] The invention relates to the technical field of production methods for mechanical parts, in particular to a processing technology for a shift fork of an automobile. Background technique [0002] Automobile shift forks are usually made of cast iron and cast aluminum. The first kind of shift fork is welded on the shift fork shaft, and moves together with the shift fork shaft to realize shifting. The overall structural strength is strong. The second is that the shifting fork shaft is fixed, and the shifting fork slides on the shifting fork shaft to realize shifting, and the overall structure is lighter in weight. [0003] At present, for the existing automobile shift fork, although the overall structure of the cast iron fork is strong, it is necessary to process the whole whether it is drilling or grinding on the combined machine tool, and the overall weight is heavier. Installation and positioning conversion are very troublesome, and although the light ...
