Description
Technical field
The present invention relates to a kind of gripping unit, specifically a kind of bent axle air clamper.Fixing use when it is suitable for axial workpiece and carries out oscillating aging.
Background technology
We know, in the axial workpiece manufacturing processed, since stressed or be heated inhomogeneously, innerly produce uneven plastic deformation, after processing, all there is unrelieved stress.Unrelieved stress is the major reason of hardware cracking or distortion, greatly influences the fatigue strength of hardware and the stability of dimensional precision.Eliminating unrelieved stress is crucial task of mechanical processing industry.Oscillating aging (VSR) be exactly through apply that method for oscillating reduces or the homogenizing member in unrelieved stress, thereby improve the working strength of member, reduce to be out of shape and the precision of stable dimensions.When carrying out oscillating aging in the past, axial workpiece is tiled on the vibrating bottom plate, and compresses with a plurality of bolts.Therefore, limited by vibrating bottom plate, the quantity of an oscillating aging is few big or smallly, and because will tighten a plurality of bolts, so labour intensity is also very big.Adopt clamp mechanism manually, clamp slow motion, labour intensity is very big.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of simple and reasonable for structure, easy to assembly, clamps soon, and labour intensity is low, is suitable for the bent axle air clamper that various many bent axles (or axle class) once clamp.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of bent axle air clamper, and it is provided with clamp body, grip finger, cylinder, pillar, conical pressure plate, pressing plate, and the clamp body level is installed on the pillar that stands on ground; It is characterized in that: install and fix plurality of V shape piece with screw on the clamp body; The vee-block zygomorphy is connected with the hinge seat, and clamp body is provided with some elongated holes, and the grip finger middle part that is provided with in pairs links to each other with the hinge seat with hinge pin; Elongated hole is passed in the bottom; The lower end is positioned at the conical pressure plate both sides that are fixed on below the pressing plate, and the cylinder symmetry is installed on the clamp body, and its piston rod is connected with the pressing plate that is positioned at the clamp body below; Cylinder piston rod drives pressing plate, conical pressure plate moves up and down, and conical pressure plate clamps grip finger or unclamps the bent axle on the vee-block.
The present invention said grip finger inboard and vee-block both sides are provided with blind hole, and symmetry is installed two springs in the blind hole, and spring makes grip finger be in open configuration all the time.
The said pressing plate of the present invention two ends are connected with the piston rod of cylinder, and the cylinder front end is provided with rubber cradle, through screw retention on clamp body.Rubber pad encloses function of shock insulation.
Be provided with rubber pad between said clamp body of the present invention and the pillar, be used for separating focus.
The inclined-plane that the said grip finger of the present invention lower end is provided with coincide with the conical pressure plate inclined-plane that is fixed on below the pressing plate.
The present invention adopts above-mentioned clamp mechanism, also installs and fixes the timeliness vibrator on the clamp body.During work, crankshaft part is clamped the position be positioned on the vee-block that some groups of grip fingers comprise, start cylinder and realize unclamping or clamping, accomplish fixing by the timeliness bent axle.Against existing technologies, the present invention is rational in infrastructure, and is easy to assembly; Reliable clamping, a plurality of timeliness axles that once can be fixedly clamped, the quantity of the axle of a timeliness of increase; Operation, easy to use; Alleviated operator's labour intensity, high efficiency, clamping is used when being suitable for that axial workpiece carried out oscillating aging.
