Background technology

The workpiece that some thin-wall workpieces and rigidity are relatively poor because the rigidity deficiency, causes plane tool marks peace face degree overproof adding, hidden danger of quality such as coordinate instability man-hour easily.Adopt the manual locking mode head it off shown in the accompanying drawing 1 at present, but the tired lock of this structure clamping, and use rear center's support bar that floats impression to occur with the tie down screw place for a long time, the unsteady support bar in center can not the effective support workpiece, and the uniformity supportability of product quality is relatively poor.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide with a kind of easy to loading and unloading, pneuma-lock auxiliary support apparatus that can effectively guarantee the thin-wall product crudy.

The utility model adopts such scheme to realize, a kind of pneuma-lock auxiliary support apparatus, comprise center float support bar, float supporting seat, plug and spring, it is characterized in that: the affixed respectively unsteady support loam cake in supporting seat above and below and float and support lower cover and constitute a cavity floats; The unsteady support bar in center passes to float and supports the centre bore that loam cake places the support lower cover that floats; The support lower cover centre bore that floats is threaded with plug; Float between support bar lower end and the plug in the spring center that is located at; Unsteady supporting seat, unsteady support loam cake and the support lower cover that floats constitute gas-tpe fitting on the cavity, in cavity, also set up the tapering piston and the steel ball of conical ER collet, band circular cone endoporus, wherein the cylindrical of the unsteady support bar in ER collet and center is slidingly matched, and the inner face of the adjacent unsteady support loam cake of big end of conical ER collet, the inner face of the adjacent unsteady support lower cover of its small end; The tapering piston bush is on the smaller diameter end periphery of support lower cover that floats, and the lower surface of tapering piston contacts with the step that supports lower cover that floats, and tapering outer surface of piston and unsteady supporting seat inwall are slidingly matched; Between the inner conical surface of tapering piston and ER collet outer conical surface, steel ball is set.

Be further characterized in that: in order to guarantee air-tightness, unsteady supporting seat is provided with sealing ring with float support loam cake and the unsteady lower cover junction of supporting, the tapering piston is provided with sealing ring with unsteady support lower cover and unsteady supporting seat contact position, also is provided with sealing ring on the unsteady support bar in center and the support loam cake mating surface that floats.

Be further characterized in that: the tapering of described ER collet outer conical surface is consistent with the internal taper hole tapering of tapering piston, and the outer conical surface of ER collet cooperates by steel ball with the internal taper hole face of tapering piston.

Be further characterized in that: also needle roller can be set between described tapering piston and the ER collet.

During work, with clamping workpiece on frock, make the spring compression by the unsteady support bar in adjustment center, and use cylinder to compress, with an end tracheae air inlet of hand control valve control bracing or strutting arrangement, air pressure promotes the tapering piston and moves up, because the effect of tapering then, steel ball or needle roller and tapering piston produce interference makes the distortion of elasticity ER chuck with the center support bar locking of floating, and guarantees to add the man-hour workpiece and can not produce displacement.After processing, use the other end tracheae air inlet of hand control valve control bracing or strutting arrangement, air pressure promotes the tapering piston and moves down, and steel ball or needle roller and tapering piston produce the gap makes elasticity ER chuck recover distortion, spring reset, center float support bar by the spring force return that moves up.

The utility model adopts gas to promote the tapering piston, thereby utilizes the ER collet distortion locking center support bar that floats, can the effective support workpiece, guarantee the uniformity of product processing quality.Whole apparatus structure is simple, convenient mounting and clamping.
