Description
Technical field
The invention belongs to fixture, be specifically related to a kind of valve body flat grinding jig.
Background technology
At present, during with steel ball processing valve body, usually adopt Linear cut, but it is lower to there is cutting efficiency, and body size is difficult to ensure.If higher to valve body plane smoothness requirements, follow-uply also need special grinder to carry out attrition process to valve body plane, its equipment investment is higher.
Summary of the invention
The object of this invention is to provide a kind of valve body flat grinding jig, the machining accuracy of valve body can be guaranteed, and the working (machining) efficiency of valve body can be improved.
In order to achieve the above object, valve body flat grinding jig provided by the invention, comprise chuck body, pressing plate, clamping screw and adjustment screw, described pressing plate totally two, be arranged symmetrically in the both sides, front and back of chuck body, and be fixed in chuck body by the clamping screw run through, dovetail groove through before and after having in the upper end of chuck body, this dovetail groove surrounds the cavity holding steel ball by two pressing plates, the degree of depth of described dovetail groove is greater than the radius of steel ball, be less than the diameter of steel ball, at least one steel ball compact heap is provided with in described dovetail groove, described adjustment screw is against on steel ball compact heap through after pressing plate.
Be preferably, the cross section of described steel ball compact heap is the isosceles trapezoid that upper end is little, lower end is large, and the cross section of steel ball compact heap and the shape of dovetail groove suitable.
Be preferably, described in each, the both ends of dovetail groove respectively arrange a steel ball compact heap, and each steel ball compact heap correspondence is provided with an adjustment screw.
Described chuck body is cuboid, and the length of fore-and-aft direction is less than the length of left and right directions; The quantity of described dovetail groove is 5 ~ 10, many one of the quantity of the number ratio dovetail groove of described clamping screw, and clamping screw and dovetail groove are arranged alternately.By optimizing the quantity of the shape of chuck body, dovetail groove and clamping screw, both adding the amount of each processing steel ball, having in turn ensure that the reliability that chuck body is connected with pressing plate.
Beneficial effect of the present invention:
(1) utilize dovetail groove, steel ball compact heap, adjustment screw to be pinned by steel ball, the position of steel ball in plain grinding process is fixed, ensure that the machining accuracy of valve body, improve the working (machining) efficiency of valve body;
(2) when machining high-precision valve body, adopt general plain grinding lathe just can reach high-precision requirement, reduce the input of equipment;
(3) structure of this fixture is simple, is easy to processing;
(4) in process, only micrometric depth gauge need be adopted just to measure valve body level size, and operation is very easy, quick.
