Preparation method of transmission shifting fork assembly

Abstract

The invention discloses a preparation method of a transmission shifting fork assembly, and relates to the technical field of mechanical part production methods. The method comprises the following steps of selecting raw materials, preparing a shifting fork body, preparing shifting fork legs, polishing to remove burrs, assembling parts, and conducting cleaning and inspection. By adoption of the method, the shifting fork body and the shifting fork legs which are made of different materials are adopted, a novel shifting fork product is manufactured in a split assembling mode, the shifting fork product can be completely held and clamped in the horizontal direction and the vertical direction under the rotating working condition, and meanwhile the shifting fork body and the shifting fork legs are matched with the assembling end face position between the shifting fork body and the shifting fork legs, and the torsional moment of a half-thread stud and a chuck in the rotating process of the shifting fork is greatly reduced, so that the overall structural strength of the shifting fork is guaranteed, and the purpose of reducing the weight of the shifting fork is achieved on the premise that the structural strength is guaranteed. A positioning mechanism and a rotary clamping mechanism are arranged on a rack, and automatic assembly of the shifting fork body and the shifting fork legs can be achieved under driving of a first driving motor and a second driving motor.

Description

technical field [0001] The invention relates to the technical field of production methods of mechanical parts, in particular to a production method of a shift fork assembly of a transmission. Background technique [0002] Automobile shift fork assemblies are usually made of cast iron and cast aluminum. The first type of shift fork is welded on the shift fork shaft. When shifting gears, it moves together with the shift fork shaft to achieve shifting. The overall structural strength is strong. , the second is that the shift fork shaft is fixed, and the shift fork slides on the shift fork shaft to realize gear shifting, and the overall structure is lighter in weight. [0003] At present, for the existing automobile shift fork assembly, although the overall structure of the cast iron shift fork is 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. , disassembly and positioning convers...

[0003] At present, for the existing automobile shift fork assembly, although the overall structure of the cast iron shift fork is 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. , disassembly and positioning conversion are very troublesome, and although the light-weight cast aluminum shift fork improves the strength by setting reinforcement ribs at the corners, due to the relatively complicated structure, it is difficult to fully polish the multi-position surface, and the overall strength still needs to be strengthened
