Abstract
The utility model relates to a fixing base for a ball valve grinding tool. The fixing base for the ball valve grinding tool comprises a fixing gasket. Two rows of threaded through holes are distributed in the circumferential faces of the outer side of the fixing gasket in the axial direction. The number of each row of threaded through holes is four. Each row of the threaded through holes are evenly distributed in the same circumferential face of the fixing gasket. Bolts are installed inside the threaded through holes. A disc base is connected to the lower end face of the fixing gasket. A fixing hole is formed in the center of the disc base. The fixing base for the ball valve grinding tool has the advantages of being simple in structure, low in cost, convenient to operate and reliable in positioning and fixing.
Description
Technical field
The utility model relates to a kind of grinding tool, specifically a kind of holder for ball valve grinding tool.
Background technology
Grinding is with lap tool and abrasive material, from surface of the work, to grind off one deck a kind of abrasive material precision machining method of metal as thin as a wafer on fine finishining basis, belongs to fitter process.For improving the sphere fineness of ball for ball valve, improve the sealing property between spheroid and valve seat, conventionally on ball seal face (sphere), coat abrasive pastes, then contact with each other and grind with two sealing surfaces, thereby improve the flatness between sealing surface.The utility model for be circular seal counterpart, as seal configurations such as gate valve flap, stop valve clack, circular spools, by the seal of the two cooperation is clamped and carried out grinding, improve the cooperation between sealing surface, guarantee seal sealing effectiveness.There is complex structure, awkward defect in the holder of tradition grinding tool.
Summary of the invention
The deficiency existing for prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, the holder of the ball valve grinding tool of convenient fixing.
For achieving the above object, the utility model provides following technical scheme: a kind of holder of ball valve grinding tool, comprise retaining washer, retaining washer outer circumference face is provided with the two row's tapped through holes that distribute vertically, every row's tapped through hole has four, and every row's tapped through hole is evenly distributed on the same periphery of retaining washer, and bolt is housed in tapped through hole, retaining washer lower surface is connected with disc base, and described disc base center has fixing hole.
By adopting technique scheme, adopt the tapped through hole of two row's axial distribution, seal in retaining washer is realized to axial two point locations to be fixed, prevent axial wobble, every row's tapped through hole is evenly distributed on the same periphery of retaining washer simultaneously, clamping force is uniformly distributed during the seal of bolt in the packing ring that is fixedly clamped, can make its maintenance level, there will not be inclination, avoid seal loading imbalance and cause sealing surface to occur deviation, there will not be sealing surface in process of lapping, to occur tilting or dimensional error.
The utility model is further set to: described two row's tapped through holes are axially and are dislocatedly distributed.
By adopting technique scheme, realize the location of seal fixing more reliable.
The utility model is further set to: described disc base and retaining washer coaxially arrange.Fixing hole in disc base is for fixing disc base to use, disc base makes fixing hole and retaining washer coaxial with the coaxial placement of retaining washer, like this disc base fixing after when the seal in retaining washer grinds, disc base stress balance there will not be skew, guarantees normally carrying out of grinding.
The utility model is further set to: on described disc base, a side relative to retaining washer is extended with positioning sleeve vertically, and fixing hole forms on positioning sleeve.
By adopting technique scheme, the convenient orientation assemble to disc base, assembles solid and reliablely, and after disc base is fixing, when the seal in retaining washer grinds, disc base stress balance there will not be skew, and what guarantee to grind normally carries out.
The utility model is further set to: the screw rod end movable sleeve of described bolt is connected to clamping cap, the diameter of described clamping cap is less than tapped through hole, Compress Spring is housed in clamping cap, and described Compress Spring one end is against clamping cap bottom, the screw rod end end butt of the other end and bolt.
By adopting technique scheme, when being locked seal, compression springs urges clamping cap, realizes the pretightning force certain to seal, improves the coupling mechanism force to seal, realizes fixing-stable reliable.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the fixed seat structure schematic diagram of the utility model specific embodiment ball valve grinding tool;
Fig. 2 is the utility model specific embodiment disc base structural representation;
Fig. 3 is the utility model specific embodiment bolt arrangement schematic diagram.
The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the holder of the disclosed a kind of ball valve grinding tool of the utility model, comprise retaining washer 1, retaining washer 1 outer circumference face is provided with the two row's tapped through holes 4 that distribute vertically, every row's tapped through hole 4 has four, every row's tapped through hole 4 is evenly distributed on the same periphery of retaining washer 1, and two row's tapped through holes 4 are axially and are dislocatedly distributed.Bolt 2 is housed in tapped through hole 4, and retaining washer 1 lower surface is connected with disc base 3, and described disc base 3 centers have fixing hole 32.For improving the coupling mechanism force of 2 pairs of seals of bolt, the screw rod end of described bolt 2 is provided with polished rod 21, the diameter of polished rod 21 is less than the screw diameter of bolt 2, polished rod 21 end ends (being the screw rod end end of bolt) are provided with defining flange 211, on the polished rod 21 of bolt 2, movable sleeve is connected to clamping cap 22, and spacing on polished rod 21; The diameter of described clamping cap 22 is less than tapped through hole 4, is convenient to bolt through tapped through hole; Compress Spring 23 is housed in clamping cap 22, and described Compress Spring 23 one end are against clamping cap 22 bottoms, the screw rod end end butt of the other end and bolt 2.Described disc base 3 coaxially arranges with retaining washer 1, and retaining washer 1 adopts and is weldingly fixed on disc base 3.On described disc base 3, a side relative to retaining washer 1 is extended with positioning sleeve 31 vertically, and fixing hole 32 forms on positioning sleeve 31.The utility model only need be fixed disc base in use, then by bolt 2, seal is clamped and can be ground, and simple in structure, cost is low, operates also very convenient.
