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 the similar large batch of class lathe headstock gear shift fork of structure.
Background technology
Special fixture in the market for shift fork part generally adopts customization, and machining factory is generally that our factory researches and develops processing and manufacturing special fixture voluntarily when processing part in enormous quantities.The wear extent of the special fixture when producing clamping in enormous quantities can increase gradually to adopt the weak point of special fixture to be just, thus affect clamping precision, cause Product Precision to reduce, and component also need frequent 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 a kind of practicality through the process of physical vapour deposition (PVD) diamond-like coating, have high-wearing feature, for the drilling machine fixture of shift fork pilot hole processing, play great role aborning.
Summary of the invention
The present invention is the guiding mechanism of some shift fork special fixtures before will improving, clamp system, the process of physical vapour deposition (PVD) diamond-like coating is carried out to this guiding and clamp system, and a kind of drilling machine coated fixture of shift fork pilot hole is provided, this fixture is by diamond-like coating process vee-block, backing pin, after drill bushing, wearability strengthens, clamping and machining accuracy get a promotion further, the wearability solving this fixture is low, precision reduces gradually, efficiency is poor, component is frequently changed, redesign the weak points such as manufacture, make operative more simple, thus increase substantially the production efficiency of part in enormous quantities.
The technical scheme that the present invention is taked for achieving the above object is: a kind of drilling machine coated fixture of shift fork pilot hole, 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, be provided with removable lining between drill bushing and fixture pressing plate, pressing plate is fixedly connected on clamp body top; The shifting fork positioning mechanism be made up of vee-block, base, backing pin is fixedly connected with below pressing plate, before clamp body, the spiral rewind clamp system that shifting fork positioning mechanism is made up of screw rod, pullover, nut, handle previously by support installing, 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 sunk screw is fixed on clamp body horizontal plane, and its locating surface is horizontal positioned, and backing pin inserts in the hole that clamp body processes.The centre bore connecting screw rod of support, screw front end connects pullover, spiro rod rear end connecting handle, and fixes 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, can the effectively friction and wear behavior of reinforcement and hole machined efficiency through diamond-like coating process.Clamp body and pressing plate are bolted, and integral rigidity is better, not easily deforms, can keep good machining accuracy in process.The clamping force of the clamp system of this fixture, mainly by the feature that screw mechanism provides, has clamping force large, and clamping force is stablized, clamp system is with features such as auto-lock functions, screw mechanism, with rewind groove, can increase substantially the efficiency of workman in clamping, reduces labour intensity.
This fixture, can by changing fixture pressing plate, drill bushing when the shift fork hole in piece part that processing structure is similar, 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.
Accompanying drawing explanation
Fig. 1 is structure partial sectional 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, the shift fork pilot hole boring grab of band 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 process, 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, can change when drilling different size shift fork.The location of shift fork adopts vee-block 14, the hollow base 3 of annular and backing pin 15 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 plane, locating surface is horizontal positioned, backing pin 15 inserts in the hole that clamp body 4 processes, the free degree that during restriction drilling, shift fork rotates around Z axis.The spiral rewind clamp system 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 that vee-block locating surface forms.The centre bore connecting screw rod 18 of support 20, screw rod 18 front end connects pullover 17, screw rod 18 rear end connecting handle 22, and is locked with nut 19.When clamping, screw rod 18 can exit clamping fast, and distance part has suitable distance, facilitates shift fork part to take out from fixture.
