Description
Technical field
The present invention relates to a kind of shift fork pilot hole drilling machine special fixture with physical vapour deposition (PVD) diamond-like coating, be applicable to the pilot hole drilling processing of a large batch of class lathe headstock gear shift fork of structural similarity.
Background technology
Generally adopt customization for the special fixture of shift fork part in the market, machining factory is generally that our factory researches and develops processing and manufacturing special fixture voluntarily in the time of processing part in enormous quantities.Adopt the weak point of special fixture to be just that the wear extent of special fixture in the time producing clamping in enormous quantities can increase gradually, thereby affect clamping precision, cause Product Precision to reduce, and member also needs frequently to change and to manufacture and design the cycle long, the amount of labour is large, causes production efficiency low.The present invention is directed to the structure of the gear shift fork part of lathe headstock, processing technology, design processing through physical vapour deposition (PVD) diamond-like coating of a kind of practicality, there is drilling machine fixture high-wearing feature, that process for shift fork pilot hole, play aborning great role.
Summary of the invention
The present invention is the guiding mechanism of some shift fork special fixtures before will improving, clamp mechanism, this guiding and clamp mechanism are carried out to the processing of physical vapour deposition (PVD) diamond-like coating, and the drilling machine that a kind of shift fork pilot hole is provided coating fixture, this fixture is processed vee-block by diamond-like coating, backing pin, after drill bushing, wearability strengthens, clamping and machining accuracy further get a promotion, the wearability that has solved this fixture is low, precision reduces gradually, efficiency is poor, member is frequently changed, redesign the weak points such as manufacture, workman is operated more simple, thereby increase substantially the production efficiency of part in enormous quantities.
The technical scheme that the present invention taked is for achieving the above object: a kind of drilling machine of shift fork pilot hole coating fixture, comprise clamp body, pressing plate, lining, drill bushing, base, vee-block, backing pin, pullover, screw rod, nut, support, be characterized in: drill bushing is positioned on fixture pressing plate, and be fixedly connected with fixture pressing plate, between drill bushing and fixture pressing plate, be provided with removable lining, pressing plate is fixedly connected on clamp body top; Below pressing plate, before clamp body, be fixedly connected with the shifting fork positioning mechanism being formed by vee-block, base, backing pin, before shifting fork positioning mechanism, by support, the spiral rewind down clamp mechanism being made up of screw rod, pullover, nut, handle is installed, support is fixedly connected on clamp body.
The backing pin hole inwall of the surface of vee-block, the surface of backing pin, drill bushing inwall, clamp body all scribbles diamond coatings.Vee-block is fixed in clamp body vertical elevation, and its locating surface is perpendicular to base, and base is fixed on clamp body horizontal plane with sunk screw, and its locating surface is horizontal positioned, and backing pin inserts in the hole processing on clamp body.The centre bore connecting screw rod of support, screw front end connects pullover, spiro rod rear end connecting handle, and fix with nut check.
The invention has the beneficial effects as follows:
Whole fixture is made up of two major parts, clamp body and pressing plate.Clamp body, vee-block, backing pin are through diamond-like coating processing, the effectively friction and wear behavior of reinforcement and hole working (machining) efficiency.Clamp body and pressing plate are bolted, and integral rigidity is better, are difficult for deforming in process, can keep good machining accuracy.The clamping force of the clamp mechanism of this fixture is mainly the feature providing by screw mechanism, has clamping force large, and clamping force is stable, clamp mechanism is with features such as auto-lock functions, screw mechanism, with rewind down groove, can increase substantially the efficiency of workman in clamping, reduces labour intensity.
This fixture, can be by changing fixture pressing plate, drill bushing in the time of the similar shift fork hole in piece part of processing structure, lining, the parts such as vee-block, rapid refit is suitable drilling clamp, reduce the manufacturing cost of factory's fixture, improve the utilization rate of special fixture, be of practical significance in process of production.
Brief description of the drawings
Fig. 1 is structure partial cutaway view of the present invention;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, shown in 2, shift fork pilot hole boring grab with diamond-like coating of the present invention, comprises screw 1, packing ring 2, base 3, clamp body 4, alignment pin 5, bolt 6, soket head cap screw 7, packing ring 8, alignment pin 9, drill bushing 10, housing screw 11, lining 12, pressing plate 13, vee-block 14, backing pin 15, screw 16, pullover 17, screw rod 18, nut 19, support 20, pressing plate 21, handle 22.
The backing pin hole inwall of alignment pin, vee-block 14, drill bushing 10, clamp body 4 is through diamond-like coating processing, drill bushing is positioned on fixture pressing plate 13, adopt renewable bushing 10, use housing screw 11 to be fixed, in the drill bushing hole of pressing plate 13, add the lining 12 that can change.Pressing plate 13 adopts soket head cap screw 7 to be connected with clamp body 4, in the time of drilling different size shift fork, can change.The location of shift fork adopts vee-block 14, hollow base 3 and the backing pin 15 of annular to position.Vee-block 14 uses soket head cap screw to be fixed in clamp body 4 vertical elevation, locating surface is perpendicular to base 3, base 3 adopts sunk screw to be fixed on clamp body 4 horizontal planes, locating surface is horizontal positioned, backing pin 15 inserts in the hole processing on clamp body 4, the free degree that when restriction drilling, shift fork rotates around Z axis.The spiral rewind down clamp mechanism of the part composition fixtures such as screw rod 18, pullover 17, nut 19 and handle, be installed in the hole of support 20, support 20 uses soket head cap screw to be fixed on clamp body, and bracket holes axis is vertical with the positioning datum of vee-block locating surface composition.The centre bore connecting screw rod 18 of support 20, it is pullover 17 that screw rod 18 front ends connect, screw rod 18 rear end connecting handles 22, and be locked with nut 19.In the time of clamping, screw rod 18 can exit clamping fast, and has suitable distance apart from part, facilitates shift fork part to take out from fixture.
