Description
Technical field:
This utility model relates to ball for ball valve technical field of processing equipment, particularly to a kind of small ball valve spheroid fine grinding frock.
Background technology:
In prior art, ball for ball valve is after carrying out preliminary mechanical lapping, and machining accuracy is relatively low, therefore also need to rely on and manually carry out refining, polishing, during underhand polish, need the most well to control ball for ball valve and processing grinding tool, guarantee fine grinding, the effect of polishing, work efficiency is relatively low.
Utility model content:
This utility model provides a kind of small ball valve spheroid fine grinding frock, solves ineffective problem in prior art.
Technology solution of the present utility model is as follows: a kind of small ball valve spheroid fine grinding frock, include ball for ball valve and falsework, described ball for ball valve center has the cylindrical channel through this ball for ball valve, the driving motor being vertically arranged is installed below described falsework, the output shaft of described driving motor extends falsework straight up, and on elongated end, it is fixed with rotating disk, it is fixed with positioning chuck at described rotating disk upper end center, have, at described positioning chuck upper end center, the spherical groove matched with ball for ball valve, described ball for ball valve is embedded in spherical groove, and cylindrical channel is vertically arranged, described positioning chuck is arranged over gag lever post, described gag lever post two ends are fixed on rotating disk by screw bolt and nut.
As preferably, described driving motor is reducing motor.Ball for ball valve velocity of rotation is suitable, it is ensured that grinding effect.
As preferably, described spherical groove depth size is the 1/3～1/2 of cylindrical channel height size.Ball for ball valve is embedded in spherical groove, and clamping structure is reliable and stable, and does not affect the grinding held on which.
As preferably, described in two, bolt one end is fixed on rotating disk, and the other end extends straight up, and bolt described in two is all bolted with two nuts, on the sleeve bolt between two nuts respectively of described gag lever post two ends.So can be by adjusting two nuts position on bolt so that gag lever post is pressed on ball for ball valve upper end,
As preferably, on the extended line of the cross-sectional diameter that bolt described in two is positioned at spherical groove.So make the gag lever post can be spacing to its compression directly over ball for ball valve, it is ensured that clamping is reliable.
The beneficial effects of the utility model are: by designing easy grinding tool, drive at reducing motor and on the rotating disk rotated, positioning chuck and gag lever post are set ball for ball valve is carried out clamping fix, when grinding, polishing, working trajectory is uniform, grind dead angle without leakage, make whole spheroid comprehensively be ground, polish, and the processing of sphere precision is guaranteed.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 2, falsework；4, motor is driven；5, rotating disk；6, positioning chuck；7, spherical groove；8, gag lever post；9, bolt；10, nut.
Detailed description of the invention:
In conjunction with accompanying drawing 1, this utility model one small ball valve spheroid is refined frock, be described further.
A kind of small ball valve spheroid fine grinding frock of the present utility model, include ball for ball valve and falsework 2, ball for ball valve 1 center has the cylindrical channel through this ball for ball valve, the driving motor 4 being vertically arranged is installed below falsework 2, the output shaft driving motor 4 extends falsework 2 straight up, and on elongated end, it is fixed with rotating disk 5, it is fixed with positioning chuck 6 at rotating disk 5 upper end center, the spherical groove 7 matched with ball for ball valve is had at positioning chuck 6 upper end center, ball for ball valve is embedded in spherical groove 7, and cylindrical channel is vertically arranged, positioning chuck 6 is arranged over gag lever post 8, gag lever post 8 two ends are fixed on rotating disk 5 by bolt 9 and nut 10.
Further, driving motor 4 is reducing motor.
Further, spherical groove 7 depth size is the 1/3 of cylindrical channel height size.
Further, two bolt 9 one end are fixed on rotating disk 5, and the other end extends straight up, and two bolts 9 are all bolted with two nuts 10, on the sleeve bolt 9 between two nuts 10 respectively of gag lever post 8 two ends.
Further, on the extended line of the cross-sectional diameter that two bolts 9 are positioned at spherical groove 7.
Operation principle of the present utility model is: be embedded by ball for ball valve in spherical groove 7, and cylindrical channel is vertically arranged, then pass through the adjusting nut 10 position on bolt 9, gag lever post 8 is made to be pressed on ball for ball valve upper end, finally start and drive motor 4, ball for ball valve is refined by workman's hand-held grinding tool, is polished.
The foregoing is only preferred embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
