Description
Technical field
The utility model relates to a kind of pump cover and adds man-hour for fixing fixture.
Background technology
At present, pump cover is very important part of high pressure water-injection pump, and requirement on machining accuracy is very high, and for example one of them model need to process six
hole and R52 half round concave shape, require 6 deciles uniform, and position accuracy demand is at ± 0.2 degree, existingly adds man-hour, adopts common clamp multiple clamping processing on milling machine, the dimensional accuracy in hole, and six
hole and R52 half round concave shape positional precision are difficult to ensure.
Summary of the invention
The utility model is for the proposition of above problem, and a kind of accurate positioning pump cover of research and design fixture is adding man-hour requirement multiple clamping in order to solve existing pump cover, and the dimensional accuracy of hole and half round concave shape and positional precision do not reach the shortcoming of requirement.The technological means that the utility model adopts is as follows:
A kind of accurate positioning pump cover fixture, comprising: clamping fixture seat, alignment pin, mandrel, pressing plate and clamp nut; Described clamping fixture seat has the base and fixing vertical plate vertical with base that level is laid, described mandrel is horizontally fixed on the centre position of clamping fixture seat vertical plate, on vertical plate under mandrel, offer lateral aperture, pump cover is arranged on mandrel, alignment pin puts in location in the halving hole on pump cover through the lateral aperture on clamping fixture seat and fixes, pump cover outside on mandrel is provided with pressing plate, and the double-screw bolt that clamp nut and mandrel outside have is threaded, and clamp nut is spirally connected fixing near pressing plate.
On pump cover, evenly offering six as preferred described halving hole, is concentric circles through circle and the circular pump cover in six halving hole centers of circle.
Be provided with same base, baffle that vertical plate is vertical as the two ends of preferred vertical plate, the same base of baffle, vertical plate are fixedly connected with.
Compared with the prior art, accurate positioning pump cover fixture described in the utility model, pump cover can be arranged on mandrel, alignment pin puts in location in the halving hole on pump cover through the lateral aperture on clamping fixture seat and fixes, pressing plate is installed in mandrel outside, fastening by the double-screw bolt on clamp nut and mandrel, clamp nut is pressed against pressing plate on pump cover, make pump cover firmly clamping on described accurate positioning pump cover fixture, thereby can process dimensional accuracy and the position of hole and half round concave shape accurately, in the time of needs dislocation angle, unclamp clamp nut, extract alignment pin out, pump cover is turned to suitable location, alignment pin is injected in the halving hole of correspondence position, clamp nut is screwed tight fixing, again process, avoid the trouble of plain clamp multiple clamping, improve the efficiency of pump cover processing.
Accurate positioning pump cover fixture described in the utility model has novel structure, it is easy to process, assemble quick, easy to use, machining accuracy advantages of higher, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
