Pull-fork assembly includes shift fork, the axle sleeve being arranged on shift fork and blade, and its bottom bracket axle and blade all keep with shift fork place plane
Plumbness, actual adding also can carry out bore hole by countershaft set man-hour.The setting of locating slot is the feature according to axle sleeve so that axle sleeve energy
Enough being inserted in locating slot, the effect identical with locating slot is not only played in hole, location simultaneously, also allows for adding countershaft set in man-hour and carries out
Bore hole.According to the architectural feature of processed pull-fork assembly, its blade is arranged on by axle sleeve, and is parastate with axle sleeve, at quilt
After being placed on clamp body, blade is inserted in stopper slot just, and whole pull-fork assembly is played spacing by blade by stopper slot
Effect, carrying bolt provides stable support for blade, and blade is carried out spacing and fixing by caging bolt further, it is ensured that group
Fork assembly work in-process is more stable.First hydraulic jack and the second hydraulic jack are by being arranged on the pressure of respective piston rod upper end
It is fixing that block carries out compressing to processed pull-fork assembly.This utility model is simultaneously solid to both sides and the blind end of shift fork opening
Fixed, by pull-fork assembly clamping on clamp body can be made firm, the most simple, convenient, laborsaving；On the other hand, energy
Enough utilize same set of fixture to realize in the minds of prong milling face and axle sleeve bore hole work in-process to be sequentially completed, it is to avoid repeated clamping impact
The disadvantage of machining accuracy, is effectively increased production efficiency, and ensure that product is stable.
Further, in order to alleviate the weight of clamp body, optimize the structure of clamp body, manufacture clamp body and also to save
Material and reduce its production cost, the middle waist hollow out at described clamp body goes out the waist hole of multiple rectangle.
Further, in order to adapt to the shape facility of processed shift fork, simultaneously facilitate in the course of processing milling cutter to processed
Shift fork two prong inwall carries out milling face, and the inwall of described clamp body fork is circular arc, offers manhole on base plate, institute
The edge of the lower edge and described manhole of stating clamp body fork inwall overlaps.
Further, described base plate is rectangular flat structure, has string at base plate two ends near the position of termination and installed
Hole.
Beneficial effect: this utility model is according to the architectural feature of processed pull-fork assembly, and ad hoc have for adaptive support
Bolt and caging bolt, play and support and spacing effect, can meet milling face and requirement that bore hole is processed simultaneously is designed, structure
Think rationally, it is to avoid the drawback of multiple clamping location, it is ensured that machining accuracy, and use the oil cylinder fixing as the compressing of external force source
Pull-fork assembly so that it is keep more stably state on clamp body, further increases stability and the precision of processing；Additionally
Four pull-fork assemblies can be realized the most processed, improve working (machining) efficiency.
