Abstract
The design was studied that was focused on transmission with the shift fork of
the protocols and proprietary drilling fixture design, whose contents were included
that the use of blades, the blades type of production and the relevant technical
requirements. On this basis, the rough was chosen, and the size of the rough was
determined, and the mechanical allowances were determined. A rough map was
drawn. After carefully detailed analysis of the parts map, the benchmark was chosen,
the development of surface processing methods was determined, and the demarcation
of the processing stages was divided. According to the production process the type of
centralization and decentralization was determined, the process was reasonably
arranged, and the order and orchestrates a suitable process line were set up. Then
some detail was calculated, such as allowance, processes size and the determination of
tolerance. The amount of calculation and the calculation of the fixed time was cut.
Thus a set of reasonable card processing machinery and mechanical processes cards
were drawn up.
The second part of the design was the focus of this issue which was difficult,
who was mainly centered on proprietary drilling fixture design, Z525-use vertical
drilling, drilling screw hole design process by which a drilling fixture. Firstly fixture
was designed to clear the major tasks identified by positioning components, guidance
devices, clamping body fixture structure, access to the relevant national standards,
painting fixture assembly.
The study of the subject transmission blades was used in the transmission
gearbox shift agencies. Through the design of the transmission plectrum shift gearbox
bodies changed stalls, thus it changed the speed of automobile.
