Description
Technical field
The utility model belongs to mechanical processing technique equipment, particularly a kind of many orders of gear pump body processing tool.
Background technology
The gear pump body inner chamber holds driving gear, driven gear and side plate and bearing, the Geometrical Tolerance Principle of the depth of parallelism on the perpendicularity on the relatively large plane of dead eye, pin-and-hole and gear hole, relatively large plane, baseplane is all tighter, so many orders of pump housing requirement on machining accuracy is high.In the work in-process heart process, frock originally is for working (machining) efficiency, four gear pump bodies of a last clamping of frock, because frock is long, it is very inconvenient to load and unload, and the impulse stroke of processing is long, can not satisfy requirement on machining accuracy on the location, often produce waste product, economic loss.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, easy to use, guarantees many orders of gear pump body processing tool of requirement on machining accuracy.
The technical scheme that the utility model technical solution problem adopts is: many orders of gear pump body processing tool comprises clamp body, clamp nut, band shoulder hex nut, stud, lining one, lining two, be characterized in left above the clamp body, right both sides install respectively a locating shaft, locating shaft upper end suit lining two, lining two is installed on the centering plate, four linings one of the symmetrical insert of difference on the centering plate, per two linings one correspond respectively to two pin-and-holes of a pump housing, install respectively two linings one of a corresponding pump housing and two pin-and-holes of a pump housing with two centering pins, inside and outside both sides each symmetry two studs that are threaded respectively above the clamp body, the below fixes with clamp nut, be set with pressing plate on the stud, with the locking of band shoulder hex nut, the inner termination of the pump housing two side guides is pressed in the locating hole of pump housing both sides, stud is left, right both sides respectively are provided with a limit body and are threaded on the clamp body, fix with clamp nut, each limit body upper end is threaded soket head cap screw is housed, and soket head cap screw withstands on pump housing both sides.
The beneficial effects of the utility model are: many orders of gear pump body processing tool can be implemented in split, and is simple in structure, convenient installation, dismounting, and single frock processing stroke is short, and positioning stablity is reliable, has guaranteed the machining accuracy of product.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is that many orders of gear pump body tool structure for processing master looks and figure cuts open in office.
