Abstract

The invention discloses a shifting fork machining method and relates to the technical field of machining. A shifting fork milling fixture is used for machining. The shifting fork milling fixture comprises a fixture body, wherein positioning pin shafts which are respectively matched with small end holes of two shifting forks are arranged at two sides of the fixture body in an inlaying manner; pressing plates are arranged at free ends of the two positioning pin shafts, positioned on the same side, in a sleeving manner; the middle of each pressing plate is connected with the fixture body by virtue of a bolt; a limiting block is arranged below each positioning pin shaft; and each limiting block is provided with a limiting surface which corresponds to an arc-shaped groove of a large end of the shifting fork. The method comprises the following machining methods: A, mounting the fixture; B, mounting a workpiece; C, milling a groove; and D, unloading the workpiece. Compared with the prior art, the shifting fork machining method disclosed by the invention has the advantages that four shifting forks can be clamped once for performing milling groove machining, the production efficiency is improved, and the machining cost is reduced.

Description

The processing method of shift fork
Technical field
The present invention relates to Machining Technology field, especially a kind of processing method of shift fork.
Background technology
Shift fork 101 as shown in Figure 1 and Figure 2 includes shift fork microcephaly and shift fork major part, and shift fork major part is provided with arc groove; The clamp 102 that shift fork microcephaly is provided with little head bore and stretches out laterally, clamp 102 is provided with clamp groove.Usually utilize the clamp groove of milling machine to shift fork to carry out Xiyanping injection, the processing method of current shift fork once can only carry out Xiyanping injection to a shift fork, and production efficiency is low, and processing cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing method of shift fork, once can only carry out Xiyanping injection to a shift fork, the problem that production efficiency is low with the processing method solving existing shift fork.
In order to solve the problem, the technical solution used in the present invention is: the processing method of this shift fork, a kind of shift fork milling clamper is used to process, this shift fork milling clamper includes clamp body, the alignment pin coordinated with the little head bore of two shift forks respectively is all installed with in the both sides of described clamp body, the free end being positioned at two described alignment pin of the same side is set with pressing plate, and the middle part of described pressing plate is connected with described clamp body by bolt; Be respectively equipped with limited block in the below of each described alignment pin, described limited block is provided with the confined planes corresponding with the arc groove of shift fork major part;
Its procedure of processing comprises:
A, sectional fixture: described shift fork milling clamper is arranged on the workbench of milling machine;
B, installation workpiece: the little head bore of four shift forks is set in four described alignment pin, on the confined planes being enclosed within described limited block that the arc groove of its major part is corresponding, the free end being positioned at two described alignment pin of same side is set with one piece of described pressing plate, tightens the locking nut on described bolt;
C, groove milling: start milling machine, process the clamp groove of four described shift forks successively;
D, unload workpiece: after machining, pull down two described locking nuts and two pieces of described pressing plates, take off the processing that namely four described shift forks complete this shift fork.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention can carry out Xiyanping injection by clamped one time four shift forks, and production efficiency improves, and reduces processing cost; It is convenient, simple to operate that clamping installed by shift fork.
