Abstract

The invention discloses a clamp special for shifting fork machining. The clamp special for shifting fork machining comprises a bottom plate. A first positioning pin and a first arc-shaped positioning block are used for positioning a first shifting fork and are arranged on the upper side of the bottom plate. A second positioning pin and a second arc-shaped positioning block are used for positioning a second shifting fork and are symmetrically on the upper side of the bottom plate around the center of the bottom plate. A first pre-positioning bolt is arranged at the side portion of the first shifting fork on the upper side of the bottom plate. A second pre-positioning bolt is arranged at the side portion of the second shifting fork on the upper side of the bottom plate. At least one first pressing plate is arranged on the upper side of the first shifting fork. At least one first pressing plate is arranged on the upper side of the second shifting fork. The clamp has the advantages that the clamp is reasonable in design, simple in structure, stable in performance, easy to detach and assemble and convenient to maintain, ordinary workers can complete complex machining tasks, machining accuracy is effectively ensured, the multiple shifting forks can be clamped, efficiency is improved, production cost is reduced, and the clamp is convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a special fixture, in particular to a special fixture for shift fork processing. Background technique [0002] At present, there are a wide variety of products in the shift fork series of various models, with different specifications and a large output. A fork part such as figure 1 shown. The machining process of this part is as follows: Drilling and expanding the bottom hole of the boss - drawing the big hole of the boss - grinding the convex surface of the fork - correction - turning the arc groove - heat treatment of the fork - correction after heat - drilling pin hole. The wall of this part is thin and easy to deform during processing, and the dimensional accuracy of the product is required to be high. In mass production, there are problems such as difficulty in ensuring processing accuracy and low processing efficiency. Contents of the invention [0003] The...
