Description
Art
The utility model relates to a kind of jig, particularly accurate Hang grinding machine private use plane floating clamp.
Background technology
Honing process belongs to Precision Machining, is the last processing to inner bore of part.When endoporus for the smaller part of major diameter carries out Honing process, fixture steps up the size of power, the distribution of clamping force will directly have influence on the dimensional accuracy after work pieces process, form accuracy etc., mostly there is complex structure in current plane floating clamp, installation, maintenance difficulty; During clamp workpiece, clamp force distribution is uneven, adds and easily forms cydariform man-hour, and clamping work pieces is unstable; Floating range is difficult to regulate, and adds the processing request not reaching workpiece man-hour.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides a kind of rational in infrastructure, uniform accurate Hang grinding machine private use plane floating clamp of clamp force distribution.
The technical solution of the utility model is: a kind of accurate Hang grinding machine private use plane floating clamp, comprise clamp base and fixture, it is characterized in that being installed with supporting seat in clamp base, its intermediate part is rotatably connected with supporting seat, U-lag is had in one end of lever, cylindric guiding clamping sleeve is arranged in the U-lag on lever by being fixed on two bearing pins symmetrical on its periphery, the clamp base of the other end bottom of lever is provided with compressed oil cylinder, and the top of the piston rod in compressed oil cylinder is corresponding with below the other end of lever.
Above-mentioned lever is be connected with lever with the oscillating bearing be arranged on connecting axle by the connecting axle be arranged on supporting seat with being rotatably connected of supporting seat, and the endoporus on oscillating bearing overcoat and lever matches, and oscillating bearing inner sleeve and connecting axle match.
In the above-mentioned corresponding position, top with piston rod, adjustment screw is installed.
Above-mentioned supporting seat upper surface is fixed with elasticity orifice plate, the hole on elasticity orifice plate and the cylindric clamping sleeve endoporus that lead concentric, and the aperture on elasticity orifice plate is greater than cylindrical shape leads the endoporus of clamping sleeve.
Above-mentioned clamp base leads with cylindrical shape clamping sleeve corresponding position is provided with locating piece.
Above-mentioned locating piece has 3, at least one locating piece is provided with adjusting bolt wherein.
The technical solution of the utility model has following characteristics:
1, adopt lever principle, thrust derives from compressed oil cylinder, so just can effectively ensure that part to be processed is in stable state in process;
2, cylindric guiding clamping sleeve is adopted to compress workpiece to be machined, simultaneously due between cylindrical shape guiding clamping sleeve and lever, lever and base adopt swingable floating connection, so just effectively can change thrust present situation pockety, reduce the distortion of part, improve machining accuracy;
3, cylindric guiding clamping sleeve is both as compressing original paper, and its endoporus serves again guide effect when honing head enters endoporus simultaneously, makes the simple and reasonable for structure of this device;
4, thrust is easy to adjust.By the upper-lower position of adjustment lever one end adjustment screw, the adjustment of thrust just can be realized, convenient and simple.

Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the top view of the utility model accompanying drawing 1;
Accompanying drawing 3 is the A-A sectional view of the utility model accompanying drawing 1.
Detailed description of the invention
As shown in Figure 1, 2, 3, clamp base 2 is installed with supporting seat 12, be connected by connecting axle 6 and the oscillating bearing be arranged on connecting axle with supporting seat in the middle part of lever 4, U-lag is had at the right-hand member of lever, cylindric guiding clamping sleeve 8 is arranged in U-lag by being fixed on two bearing pins 9 symmetrical on its periphery, the clamp base of the left end bottom of lever is provided with compressed oil cylinder 1, corresponding position, piston rod 3 top in lever left end and compressed oil cylinder, is provided with adjustment screw 5.
Supporting seat upper surface is fixed with elasticity orifice plate 7, the hole on elasticity orifice plate and the cylindric clamping sleeve endoporus that lead concentric, and the aperture on elasticity orifice plate is greater than cylindrical shape leads the endoporus of clamping sleeve.Clamp base leads with cylindrical shape clamping sleeve corresponding position is provided with 3 locating pieces 10, a locating piece is provided with adjusting bolt 11 wherein.
During use, be placed on by part to be processed between clamp base 3 locating pieces, all around positioned position by 3 locating pieces to it, positioning precision can be regulated by adjusting bolt 11.
Primer fluid pressing system, piston rod in compressed oil cylinder moves up, by adjustment screw 5, lever 4, cylindric guiding clamping sleeve 8 is driven to move down, Work-sheet pressing is fixed, the bistrique of honing machine moves down, introduced in the processed endoporus of workpiece by cylindrical shape guiding clamping sleeve and carry out Honing process, after completion of processing, bistrique moves up and releases the processed endoporus of workpiece, piston rod in compressed oil cylinder moves down, and drives cylindric guiding clamping sleeve 8 to move up, just workpiece can have been taken out a circulation of processing.
Because cylindrical shape guiding clamping sleeve 8 is arranged in the U-lag on lever by two bearing pins 9 symmetrical on its cylindrical, when cylindrical shape guiding clamping sleeve bottom surface and absorption surface, can swing, so just can realize contacting with the floating of workpiece, making thrust suffered by workpiece all with being distributed on cylindric guiding clamping sleeve bottom surface, preventing the distortion that workpiece unbalance stress causes.
The object that above-mentioned supporting seat 12 upper surface is fixed elasticity orifice plate 7 is, prevents cylindric guiding clamping sleeve left rotation and right rotation angle excessive, collides, cause the damage of bistrique when causing honing bistrique to introduce with the cylindric clamping sleeve endoporus that leads.
Lever 4, while swinging around connecting axle 6, due to the sphere-contact structure of the Internal and external cycle of oscillating bearing 13, while bearing radial load and two-way axial load, can make lever do swinging by a small margin.Such cylindrical shape guiding while clamping sleeve 8 swings up and down under the drive of lever, can move back and forth relative to lever around two bearing pins 9, and lever can do swinging by a small margin simultaneously.The swing of these two kinds of different directions constitutes the activity of fixture 360 degree of scopes, thus ensures fixture and the adjustment of workpiece axiality and all using of thrust flexibly.
Adjustment screw 5 can regulate the impulse stroke of oil hydraulic cylinder 1, and the piston rod part simultaneously in oil cylinder 1 and adjustment screw are point cantact, ensure that lever can be movable around oscillating bearing in supporting seat.
