Abstract
The invention relates to the field of machining, and particularly relates to an elastic expansion sleeve clamp. The clamp comprises a mandrel, wherein one end of the mandrel is fixedly connected with a flange plate, the flange plate is connected with a machine tool spigot through a bolt, and a ladder through hole is formed in the center of the mandrel; a piston is arranged in the ladder through hole, and the other end of the piston is connected with a bolt; one end of the piston far away from the bolt is provided with a mandril connected with a hydraulic cylinder of a machine tool, an elastic expansion sleeve sleeves the mandril, and a cavity is formed by the elastic expansion sleeve and the outer surface of the mandril and is filled with a liquid filler. The elastic expansion sleeve clamp provided by the invention is simple in structure and convenient to clamp, and does not vibrate in the course of processing after the clamping, the processing precision of parts can be improved, and the labor intensity of workers can be reduced.
Description
Technical field
The present invention relates to field of machining, be specifically related to elastic expansion-sleeve fixture.
Background technology
Cylinder sleeve is one of kernel component of engine, cylinder sleeve belongs to sleeve part and uses in machinery industry widely, but due to the relation of part thickness, make clamping in part processing very difficult, there will be the not firm or clamping of clamping and make part deformation, in production in enormous quantities, turning sleeve part, workpiece easily produces distortion and affects machining accuracy on the one hand; Clamping part corrects extremely inconvenience on the other hand, and especially when endoporus is black skin, clamping is more difficult.Make production efficiency low, and then increase the labour intensity of workman, business efficiency is low.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, convenient mounting and clamping, clamping aft-loaded airfoil friction, can improve the machining accuracy of part, reduces the elastic expansion-sleeve fixture of the labour intensity of workman.
Elastic expansion-sleeve fixture of the present invention, comprise mandrel, described mandrel one end is fixedly connected with a ring flange, described ring flange is connected with lathe seam by bolt, described mandrel center is provided with a ladder hole, a piston is provided with in described ladder hole, the other end is connected with a bolt, described piston is provided with a push rod away from one end of bolt, push rod is connected with machine tool hydraulic cylinder, described mandrel is socketed with an elastic expansion-sleeve, elastic expansion-sleeve and mandrel outer surface form cavity, are filled with fluidity filler in described cavity.
Preferably, piston is provided with three seals circle, one end of described mandrel through hole connecting bolt is provided with sealing ring.
Preferably, elastic expansion-sleeve and mandrel are interference fit.
Preferably, mandrel ring flange and face of the matching radial beat eccentricity of lathe are in 0.02mm.
Structure of the present invention is simple, convenient mounting and clamping, and clamping aft-loaded airfoil friction, can improve the machining accuracy of part, reduces the labour intensity of workman.
Accompanying drawing explanation
Fig. 1 is the structural representation of elastic expansion-sleeve fixture.
Reference numeral: 1-push rod, 2-mandrel, 3-ring flange, 4-elastic expansion-sleeve, 5-bolt, 6-piston, 7-sealing ring.
Detailed description of the invention
Elastic expansion-sleeve fixture of the present invention, comprise mandrel 2, described mandrel 2 one end is fixedly connected with a ring flange 3, described ring flange 3 is connected with lathe seam by screw, described mandrel 2 center is provided with a ladder hole, a piston 6 is provided with in described ladder hole, the other end is connected with a bolt 5, described piston 6 is provided with a push rod 1 away from one end of bolt 5, push rod 1 is connected with machine tool hydraulic cylinder, described mandrel 2 is socketed with an elastic expansion-sleeve 4, elastic expansion-sleeve 4 and mandrel 2 outer surface form cavity, are filled with fluidity filler in described cavity.Piston 6 is provided with three seals circle 7, one end of described mandrel 2 through hole connecting bolt 5 is provided with sealing ring 7, and elastic expansion-sleeve 4 and mandrel 2 are interference fit.The ring flange 3 of mandrel 2 and face of the matching radial beat eccentricity of lathe are in 0.02mm.
With after mandrel 2 interference fit on lathe from car, one end of push rod 1 is connected with hydraulic jack, jack-up piston 6 forward under hydraulic jack drives, piston 6 has three seals circle 7 with liquid repellency packing leaking, the pressure of the fluidity filler generation that piston 6 compresses in mandrel 2 and ringfeder cavity acts on elastic expansion-sleeve 4 and makes ringfeder tensioner cylinder jacket.
