Description
Technical field
The utility model relates to machining fixture.The utility model is applicable to the clamp for machining of valve rod T-slot.
Background technology
When valve rod T-slot Xiyanping injection, need to be fixed valve rod, be adopt upper lower plate to be fixed by pressing plate to the stationary fixture of valve rod at present, pressing plate is manually compressed by spanner from screw rod by nut.Because its external diameter of the valve rod of same size is individual variant, so pressing plate once can only press-fit at most two valve rods, namely a valve rod is respectively pressed in both sides.Each handling expend time in many, and it is few that single press-fits valve rod quantity, and working (machining) efficiency is low.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, provides a kind of and loads and unloads convenient, that single press-fits the valve rod T-slot that quantity is many, working (machining) efficiency is high milling fixture.
The technical solution of the utility model comprises base, base plate, clamping plate, pressing plate, locating shaft, base plate is fixedly mounted on base, locating shaft is vertically mounted in the middle of base plate, base plate clamps the periphery in the middle part of valve rod between plane and clamping plate lower plane, mainly clamping plate are made up of left clamping plate and right clamping plate, the upper in-plane of left clamping plate and right clamping plate is shaped with circular arc concave surface respectively, the locating hole moving with locating shaft and coordinate is shaped with in the middle of pressing plate, pressing plate is fixedly connected with one end of depression bar in the middle of plane, the other end of this depression bar and one end of lever hinged, the other end of lever is connected with piston rod end, the end of its intermediate part and backstay is hinged, the other end of backstay and the piston cylinder of piston rod are fixedly mounted on base, pressing plate lower plane both sides are shaped with and left clamping plate respectively, the arc convex surface that on right clamping plate, plane Inner arc concave surface cooperatively interacts.
Preferably, middle being shaped with respectively in the right side of left clamping plate and the left side of right clamping plate moves with locating shaft periphery the semicircle orifice coordinated.
Preferably, circular arc concave surface and arc convex surface are the face of cylinder, the cylinder axis on this face of cylinder and be fitted in the axis being parallel of valve rod between base plate and clamping plate.
Preferably, circular arc concave surface and arc convex surface are sphere.
The utility model has the advantages that pressing plate adopts piston to promote, on clamping plate, plane and pressing plate lower plane are cooperatively interacted by circular arc concave surface and arc convex surface, left and right clamping plate can press-fit two valve rods respectively, when valve rod external diameter below same clamping plate is variant, can by the adjustment of plane circular arc concave surface cooperation position in pressing plate lower plane arc convex surface and clamping plate, compress the valve rod of two various outer diameters below same clamping plate, convenient, the single of its handling valve rod press-fits that valve rod quantity is many, working (machining) efficiency is high simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
