Abstract
The utility model discloses a valve body plane grinding clamp which comprises a clamp body, pressing plates, locking bolts and adjusting screws. The number of the pressing plates is two, and the two pressing plates are symmetrically arranged on the front side of the clamp body and the rear side of the clamp body and fixed to the clamp body through the penetrating locking bolts. The upper end of the clamp body is provided with a dovetail groove penetrating through the front portion of the upper end and the rear portion of the upper end, the dovetail groove defines a cavity used for containing a steel ball in an enclosed mode through the two pressing plates, the depth of the dovetail groove is larger than the radius of the steel ball and smaller than the diameter of the steel ball, at least one steel ball pressing block is disposed in the dovetail groove, and the adjusting screws abut against the steel ball pressing block after penetrating through the pressing plates. The valve body plane grinding clamp can guarantee the machining precision of a valve body and improve machining efficiency of the valve body.
Description
Technical field
The utility model belongs to fixture, is specifically related to a kind of valve body flat grinding jig.
Background technology
At present, during with steel ball processing valve body, conventionally adopt line cutting, but exist cutting efficiency lower, and body size is difficult to guarantee.If valve body planar light cleanliness is had relatively high expectations, follow-uply also need special grinder to carry out attrition process to valve body plane, its equipment investment is higher.
Utility model content
The purpose of this utility model is to provide a kind of valve body flat grinding jig, can guarantee the machining accuracy of valve body, and can improve the working (machining) efficiency of valve body.
In order to achieve the above object, the valve body flat grinding jig that the utility model provides, comprise chuck body, pressing plate, clamping screw and adjustment screw, totally two of described pressing plates, be arranged symmetrically in the both sides, front and back of chuck body, and be fixed in chuck body by the clamping screw running through, the dovetail groove connecting before and after having in the upper end of chuck body, this dovetail groove surrounds the cavity that holds 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, in described dovetail groove, be provided with at least one steel ball compact heap, 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 than the quantity of dovetail groove of the quantity of described clamping screw, and clamping screw and dovetail groove are arranged alternately.By optimizing the quantity of shape, dovetail groove and clamping screw of chuck body, both increased the amount of each processing steel ball, guarantee again the reliability that chuck body is connected with pressing plate.
The beneficial effects of the utility model:
(1) utilize dovetail groove, steel ball compact heap, adjustment screw that steel ball is pinned, the position of steel ball in plain grinding process fixed, guaranteed the machining accuracy of valve body, improved the working (machining) efficiency of valve body;
(2) in the time of machining high-precision valve body, adopt general plain grinding lathe just can reach high-precision requirement, reduce the input of equipment;
(3) this fixture is simple in structure, is easy to processing;
(4) in process, only need to adopt a micrometric depth gauge just can measure valve body level size, and operation is very easy, quick.
