Description
Technical field
The present invention relates to a kind of floating press mechanism that machining workpiece locus clamps that is used for.
Background technology
It is the main body of anchor clamps that the location of anchor clamps compresses, relatively succinct.In fact locate at workpiece, after the clamping, how to guarantee the position of the non-place of compressing of workpiece poor rigidity " holding tightly ", it is the difficult point of anchor clamps tackling key problem always, the machining of generally using that is used for is located at present, the floating press mechanism of clamping work pieces generally adopts: 3 fixed bearings of a sleeve clamp blank, 3 correspondences compress, increase in the poor place of workpiece rigidity and to put a supplemental support cylinder, (principle of supplemental support cylinder: the supplemental support head can move up and down, under the effect of spring force (about 1 kilogram), be close to workpiece, when hydraulic fluid pressure increases, hold the supplemental support head tightly by the thin-walled cover, play a supportive role.) entering the supplemental support cylinder when hydraulic oil, the thin-walled cover is held the supplemental support head tightly in the supplemental support cylinder, the auxiliary workpiece pressing of rotary oil cylinder then, sequence of movement is controlled by sequence valve.This structure is used relatively extensively, but defective is bigger in the practical application, is not suitable for the high workpiece of machining accuracy especially.Suppose that supplemental support cylinder thin-walled cover holds tightly, the supplemental support head can carry 400 kgfs, 200 kilograms of the auxiliary thrusts of rotary oil cylinder, and actual have two point defects: one, a supplemental support support force reduces.Theoretical calculating: 400-200=200 kilogram.Two, the workpiece deformation amount is big, and the machined surface flatness error is big.1, the supplemental support head is under 200 kilograms of thrust effects about actual rollback displacement 0.03mm.2, mainly be that workpiece face above the supplemental support head is a blank, the supplemental support head can only be a bulb, and workpiece extrudes " hole " under 200 kilograms of thrust effects, and workpiece moves down about 0.07mm.(as the workpiece of aluminium, the workpiece amount of moving down is bigger.) about two deflection 0.1mm that add up to workpiece.So such structure relatively is fit to roughing, is not suitable for fine finishining.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of clamping work pieces that can effectively prevent to make the floating press mechanism that is used for the machining clamping work pieces that causes the surface of the work distortion, keeps the flatness of surface of the work.
According to technical scheme provided by the invention, on pedestal, offer slide opening and installing hole are installed, in installing hole, be provided with clamp sleeve, the input of described clamp sleeve and power joins, in the installing hole of clamp sleeve lower end, be provided with trimmer and capping, offer the installation slide opening at trimmer, at pedestal and trimmer the axle bed that is slidingly connected in the slide opening is installed, support column and rotation and lifting oil cylinder are installed on axle bed, in the support column top ends is the lower support portion of dome shape of raising up, top ends at rotation and lifting oil cylinder piston bar is fixed with pressing plate, and the end of described pressing plate is to the lower convexity dome shape, cooperate the upper support portion that compresses with lower support portion position.
Be provided with the clamping oil pocket between clamp sleeve and the pedestal, the oil inlet pipe that is provided with on this clamping oil pocket and the pedestal joins.Between clamp sleeve that clamps the oil pocket upper and lower side and pedestal, be provided with sealing ring.Install between slide opening top and the axle bed on the pedestal and be provided with dust ring.
Offer spacing hole in the axle bed bottom, be plugged with limited post in the spacing hole, the limited post bottom is connected with the base plate of the outstanding support column sidewall of its sidewall, and limited post is fixedly connected on the axle bed bottom by base plate.There are the gap in base plate upper surface and trimmer bottom face between base plate lower surface and the capping upper surface.
During use, the rotation and lifting oil cylinder Work-sheet pressing on support column, because rotation and lifting oil cylinder, support column are fixed on the axle bed, axle bed among the present invention can upper and lowerly float in free state, the workpiece load-bearing be exactly axle bed weight, damping is very little, can not make the distortion of workpiece; Clamp sleeve does not have the trend that moves because of not having axial force, axle bed, thereby also can not make the distortion of workpiece by holding axle bed tightly, reach the purpose of holding workpiece tightly; Because clamp sleeve is not born the thrust of rotation and lifting oil cylinder,, it improves so only resisting the cutting force ability.In sum, the flatness of surface of the work increases substantially.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: on pedestal 1, offer slide opening 2 and installing hole 19 are installed, in installing hole 19, be provided with clamp sleeve 4, described clamp sleeve 4 joins with the input of power, in the installing hole 19 of clamp sleeve 4 lower ends, be provided with trimmer 16 and capping 5, clamp sleeve 4 is fixed in the installing hole 2, offer installation slide opening 18 at trimmer 16, the axle bed 7 that is slidingly connected in slide opening 2 and 18 is installed is installed support column 3 and rotation and lifting oil cylinder 8 on axle bed 7.In support column 3 top ends is the lower support portion 31 of dome shape of raising up, and rotation and lifting oil cylinder 8 compresses principle: behind 90 ° of the piston rod 81 screw down strokes of rotation and lifting oil cylinder again straight line move downward.Top ends at piston rod 81 is fixed with pressing plate 9, the end of described pressing plate 9 for to the lower convexity dome shape, cooperate the upper support portion 91 that compresses with lower support portion 31 positions.
Be provided with between clamp sleeve 4 and the pedestal 1 and clamp oil pocket 10, the oil inlet pipe that is provided with on this clamping oil pocket 10 and the pedestal 1 joins.Between clamp sleeve 4 that clamps oil pocket 10 upper and lower sides and pedestal 1, be provided with sealing ring 11.Install between slide opening 2 tops and the axle bed 7 on the pedestal 1 and be provided with dust ring 12.Offer spacing hole 13 in axle bed 7 bottoms, be plugged with limited post 14 in the spacing hole 13, there is the base plate 15 of outstanding axle bed 7 sidewalls of its sidewall limited post 14 bottoms, and limited post 14 is fixedly connected on axle bed 7 bottoms by base plate 15.Be fixedly connected with trimmer 16 in clamp sleeve 4 bottoms, and have gap 17 between trimmer 16 bottom faces and base plate 15 upper surfaces, have gap 6 between base plate 15 lower surfaces and capping 5 upper surfaces.
During use, the support column 3 that has lower support portion 31, rotation and lifting oil cylinder 8 is fixed on the axle bed 7,8 work of rotation and lifting oil cylinder, make rotation and lifting oil cylinder 8 piston rod 81 rotation and move downward, make the pressing plate 9 of piston rod 81 top ends rotate, the upper support portion 91 of pressing plate 9 Work-sheet pressing in the lower support portion 31 of support column 3 top ends, owing to exist between gap 6 and trimmer 16 bottom faces and base plate 15 upper surfaces between base plate 15 lower surfaces and capping 5 upper surfaces and have gap 17, make axle bed 7, support column 3, rotation and lifting oil cylinder 8, pressing plate 9 can fluctuate, float damping at about about 1 kilogram, can not cause workpiece deformation.Clamp sleeve 4 is held support column 3 tightly by axle bed 7, thereby reaches the purpose of holding workpiece tightly.
When piston rod 81 rotation of rotation and lifting oil cylinder 8 and move upward, make pressing plate 9 rotations of piston rod 81 top ends, loosen workpiece, clamp oil pocket 10 oil returns, make clamp sleeve 4 and axle bed 7 loosen, thereby make axle bed 7 be in free state.
