A kind of stop valve bore end face processing and milling fixture
Technical field
The present invention relates to a kind of fixture, specifically a kind of stop valve bore end face processing and milling fixture.
Background technology
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.In use, the inlet and outlet of self all needs connecting pipe to common stop valve, is therefore adding man-hour, also needs to carry out meticulous Milling Process to two bore ends of stop valve.But due to the out-of-shape of valve body outside, make specifically adding man-hour, conventional fixture cannot be fixed clamping effectively to valve body.
Summary of the invention
For above-mentioned defect, the present invention proposes a kind of stop valve bore end face processing and milling fixture.
A kind of stop valve bore end face processing and milling fixture, mainly comprise bottom block, on described bottom block, rear portion is provided with fixed mount, and described fixed mount has locating hole.
Described bottom block upper forepart is provided with bearing support with front and back sliding type, described bearing support has the ring set hole suitable with described locating hole, front end, described ring set hole is rotatably installed with bull gear, and the right-hand member of described bull gear is welded with extension board, and described extension board is articulated with cylinder.
The Inner arc side ring shape of described bull gear 4 is distributed with three spur gears suitable with bull gear, described spur gear is all connected with an axle, a described axle is all connected with a bevel gear, a described bevel gear is all connected with No. two bevel gears, described No. two bevel gears are all connected with No. two axles, described No. two axles are all connected with worm gear, described worm gear is all engaged with worm screw in front portion, described worm screw is all connected with ball-screw by shaft coupling, described ball-screw has polished rod all aside, described polished rod is all slidably fitted with the arc pressuring plate be threaded with described ball-screw.
The axis of described ball-screw, both polished rods is all suitable with the home position in ring set hole.
Described cylinder is hingedly mounted on the right front portion position of bearing support.
Valve body bore end in use, first can be passed locating hole, then slidably supported frame by the said equipment, makes another bore end of valve body through ring set hole, completes location.
In use, first bull gear is driven to rotate by cylinder, bull gear rotates and orders about three spur gears and an axle rotating Vortex, and then under a bevel gear, No. two bevel gears, the gear teeth transmission of No. two axles and wheel shaft gearing, order about worm gear, worm screw is rotated, and then allow ball-screw that arc pressuring plate can be driven under turning effort all to move to the center in ring set hole, conveniently valve body is clamped.Easy to operate.
The invention has the beneficial effects as follows:
The present invention is easy to operate, can by by the basis of valve body with regard to perform hole positioning action, successively by gear teeth transmission, wheel through-drive, Worm Wheel System, screw nut driven four kinds of modes, reach the multiple arc pressuring plate of control automatically and carry out automatic displacement, valve body is clamped.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the present invention being set forth further.
As shown in Figures 1 to 4, a kind of stop valve bore end face processing and milling fixture, mainly comprise bottom block 1, on described bottom block 1, rear portion is provided with fixed mount 2, and described fixed mount 2 has locating hole 1a.
Described bottom block 1 upper forepart is provided with bearing support 3 with front and back sliding type, described bearing support 3 has the ring set hole 3a suitable with described locating hole 1a, 3a front end, described ring set hole is rotatably installed with bull gear 4, the right-hand member of described bull gear 4 is welded with extension board 15, and described extension board 15 is articulated with cylinder 16.
The Inner arc side ring shape of described bull gear 4 is distributed with three spur gears 5 suitable with bull gear 4, described spur gear 5 is all connected with an axle 6, a described axle 6 is all connected with a bevel gear 7, a described bevel gear 7 is all connected with No. two bevel gears 8, described No. two bevel gears 8 are all connected with No. two axles 9, described No. two axles 9 are all connected with worm gear 10, described worm gear 10 is all engaged with worm screw 11 in front portion, described worm screw 11 is all connected with ball-screw 12 by shaft coupling, described ball-screw 12 has polished rod 13 all aside, described polished rod 13 is all slidably fitted with the arc pressuring plate 14 be threaded with described ball-screw 12.
The axis of described ball-screw 12, both polished rods 13 is all suitable with the home position of ring set hole 3a.
Described cylinder 16 is hingedly mounted on the right front portion position of bearing support 3.
Valve body bore end in use, first can be passed locating hole 1a, then slidably supported frame 3 by the said equipment, makes another bore end of valve body through ring set hole 3a, completes location.
In use, first bull gear 4 is driven to rotate by cylinder 16, bull gear 4 rotates and orders about three spur gears 5 and axle 6 rotating Vortex, and then under the gear teeth transmission of a bevel gear 7, No. two bevel gears 8, No. two axles 9 and wheel shaft gearing, order about worm gear 10, worm screw 11 is rotated, and then allow ball-screw 12 that arc pressuring plate 14 can be driven under turning effort all to move to the center of ring set hole 3a, conveniently valve body is clamped.Easy to operate.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed the present invention.Application claims protection domain is defined by appending claims and equivalent thereof.
