Description
Technical field
The utility model belongs to motor vehicle production frock technical field, is specifically related to a kind of transmission reverse gear shift fork side Special Fixture for Machining.
Background technology
Along with the development of auto industry, all kinds of manually (automatically) speed changer is widely applied, this just has higher requirement to the production quantity of speed changer and quality, and the quality of a speed changer quality, except the high-quality gear of needs or hydraulic gear, the quality of selector fork quality also often directly has influence on the service behaviour of whole speed changer.Back fork is one of outbalance in the multiple selector fork of speed changer, synchronized is driven by mobile back fork, the power transmission that transmission input shaft transmission can be come is to reverse gear, thus realize automobile backward, in the side structure of back fork, there is an important mating groove to coordinate with other parts simultaneously, other mating parts can be driven when gear shift fork rotates to move.Therefore, the quality of this positional structure crudy will directly affect the service behaviour of whole back fork.At present, such back fork side structure is adding man-hour, need process several times and just can complete, and there is labour intensity large, production efficiency is low, and crudy such as not easily to ensure at the defect.
Summary of the invention
The technical problem that the utility model solves there is provided a kind of structure transmission reverse gear shift fork side Special Fixture for Machining simple and reasonable in design.
The utility model adopts following technical scheme for solving the problems of the technologies described above, transmission reverse gear shift fork side Special Fixture for Machining, it is characterized in that primarily of positioning key, clamp body, axle, setting circle pin, adjustable supporting nail and circular feeler block are formed, wherein the bottom of clamp body is provided with groove, positioning key is fixed with respectively by soket head cap screw in the middle part of the convex edge of groove both sides, the top of the clamp body relative with groove is provided with round boss, the middle part of this round boss is provided with the through hole of up/down perforation, the side of axle is passed the through hole in the middle part of round boss and is fixed by nut, back fork axis hole is penetrated axle and is fixed by packing ring and nut in the upper end of axle, pitch the relative clamp body of pawl end with back fork and be provided with adjustable supporting nail, and the top of this adjustable supporting nail is in same level, clamp body inside back fork fork pawl is provided with the setting circle pin pitched pawl with back fork and contact, clamp body outside back fork fork pawl is provided with for the circular feeler block of cutter tool setting, up/down perforation is respectively equipped with and the holddown groove of opening laterally in the position at four angles of clamp body.
The utility model is by determining rational locating surface and locating hole, easily, fast can position clamping to such back fork, thus after realizing clamped one time, back fork side (side surface and groove) structure can be processed at one time, thus improve can working (machining) efficiency, reduce labour intensity, improve crudy.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model, and Fig. 2 is top view of the present utility model, and Fig. 3 is left view of the present utility model.
Drawing illustrates: 1, positioning key, 2, soket head cap screw, 3, clamp body, 4, nut, 5, axle, 6, back fork, 7, packing ring, 8, setting circle pin, 9, adjustable supporting nail, 10, circular feeler block, 11, holddown groove.
Detailed description of the invention
Describe embodiment in detail by reference to the accompanying drawings.Transmission reverse gear shift fork side Special Fixture for Machining, primarily of positioning key 1, clamp body 3, axle 5, setting circle pin 8, adjustable supporting nail 9 and circular feeler block 10 are formed, wherein the bottom of clamp body 3 is provided with groove, positioning key 1 is fixed with respectively by soket head cap screw 2 in the middle part of the convex edge of groove both sides, the top of the clamp body 3 relative with groove is provided with round boss, the middle part of this round boss is provided with the through hole of up/down perforation, the side of axle 5 is also fixed by nut 4 through the through hole in the middle part of round boss, back fork 6 axis hole is penetrated axle 5 and is fixed by packing ring 7 and nut 4 in the upper end of axle 5, pitch the relative clamp body of pawl end 3 with back fork 6 and be provided with adjustable supporting nail 9, and the top of this adjustable supporting nail 9 is in same level, back fork 6 clamp body 3 pitched inside pawl is provided with the setting circle pin 8 pitched pawl with back fork 6 and contact, can by the fork pawl quick position of back fork 6 on adjustable supporting nail 9, back fork 6 clamp body 3 pitched outside pawl is provided with for the circular feeler block 10 of cutter tool setting, up/down perforation is respectively equipped with and the holddown groove 11 of opening laterally in the position at four angles of clamp body 3.
Operation principle of the present utility model is: first axle and clamp body are connected by nut, two adjustable supporting nails and clamp body are connected, and the top that its Height Adjustment one causes adjustable supports to be followed closely is in same level, again setting circle pin is loaded in clamp body corresponding aperture, then back fork is pitched pawl and penetrate axle downwards, and back fork is pitched pawl end and adjust to two the adjustable supports side of nailing on correspondence positions, should ensure simultaneously and contact with setting circle pin inside back fork fork pawl, use packing ring and nut to be fixed after adjusting in the upper end of axle, finally circular feeler block and clamp body are connected by screw, and clamp body and milling machine table are determined the relative position of the two by two positioning keys, then connecting with bolt is fixed on milling machine table by four holddown grooves on clamp body by clamp body, multifunctional numerical control milling machine is selected to process, two working positions are according to " clamped one time, twice processing ", starting to add man-hour, need first use circular feeler block to cutter tool setting, then can process accordingly.
More than show and describe general principle of the present utility model; principal character and advantage; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
