Background technology
We know that in the manufacturing of bent axle, some processing and making process must clamp bent axle, so that carry out process operation.For example main bearing journal and connecting rod neck are bored oilhole, its processing needs respectively to join respectively a cover boring grab branch two procedures and finishes on two radial drilling machines.One procedure bores the straight oilhole of main shaft, another procedure bores the straight oilhole of connecting rod, because of every kind of crankshaft oil hole angle, crank spindle and connecting rod diameter require different, this just causes every kind of bent axle all to need two sleeve clamps, except versatility poor, also caused manufacturing cost height, the production cycle of anchor clamps long, clamping times is many, at the bottom of the efficient.
At present, in the clamp mechanism design, eccentric wheel or spiral clamp mechanism are to use more a kind of clamp mechanism.The Eccentric Clamping Mechanism process operation is convenient, clamping is rapid, and shortcoming is that clamping force and clamping stroke are all little.Spiral clamps that mechanism structure is simple, reliable clamping, versatility are good, and because lead angle is little, and the self-locking property of spiral clamp mechanism is good, clamping force and to clamp stroke all bigger, and shortcoming is manual clamping, clamps slow motion, labour intensity is big.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, easy to assembly, makes simply, and clamp speeds is fast, and labour intensity is low, is suitable for the air clamper that various axle classes clamp.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of air clamper, it comprises clamp body, supporting base, cylinder, piston rod, pressing plate, backing plate, supporting base is installed on the clamp body, backing plate is installed on the supporting base by level and vertical direction, it is characterized in that the supporting base front end installs an annular screw, the pressing plate bottom is installed on the annular screw by hinge pin, and pressing plate top is provided with two elongated holes, the piston rod front end inserts a wherein elongated hole, and both link to each other with sliding pin; Described cylinder is installed on the clamp body by a connecting seat, supporting base is provided with through hole, the piston rod of cylinder passes the through hole of supporting base, under the reciprocating of cylinder, piston rod promotes sliding pin and moves along the pressing plate elongated hole, pressing plate rotates around the hinge pin that annular screw supports, and top compresses or unclamps part.
Quadrature on two elongated hole vertical direction on the said pressing plate of the present invention, piston rod moves as straight line, and the sliding pin of its front end moves along the elongated hole of pressing plate pairwise orthogonal.
The said annular screw of the present invention is installed in the screwed hole of supporting base, and the annular screw outside also is provided with a location nut, and the two cooperates screw-in, and adjustable extension elongation of adjusting an annular screw is to be fit to the part that pressing plate clamps different-diameter.
The present invention adopts said mechanism, and it can be installed in clamp mechanism on the desired location, according to the disalignment part diameter against existing technologies, the present invention is rational in infrastructure, and is easy to assembly, low cost of manufacture, clamp speeds is fast, and highly versatile is applicable to the clamping of various axial workpieces.
