Abstract

The invention relates to an expansion fixture suitable for blank surfaces. The fixture comprises a flange, a mandrel fixed in the center of the flange, and a retainer connected with the flange through a bolt. A plurality of sliders are evenly distributed in the circumference direction of the retainer, a cushion block is fixed to each slider, a conical expansion sleeve is further arranged between the retainer and the mandrel, the conical expansion sleeve is tightly connected with the sliders, a spring is connected between the front end of the conical expansion sleeve and the flange, and the tail end of the conical expansion sleeve is provided with a fastening nut arranged on the mandrel in a sleeving mode. The expansion fixture has the advantages of being simple in structure, capable of improving production efficiency, capable of being used for machining the blank surfaces with different diameters and the like.

Description

A kind of swelling fixture being applicable to black skin

Technical field

The present invention relates to mechanical clamp technical field, particularly a kind of swelling fixture being applicable to black skin.

Background technology

For processing cast iron sleeve part, require that car both ends of the surface ensure the size of total length and car two seam simultaneously.Owing to can not clamp cylindrical by processing request, and endoporus is again black skin, is not suitable for expansion set, with in three-jaw during swollen workpiece, three-jaw is too short again, and workpiece is long and poor rigidity cannot be processed, and existing fixture processing and manufacturing is loaded down with trivial details, has and can only use once, the workpiece demand of multiple internal diameter cannot be adapted to.

Summary of the invention

For the problems referred to above, the object of this invention is to provide a kind of structure simple, enhance productivity, the swelling fixture of the workpiece of the black skin of different inner diameters size can be processed.

Realize technical scheme of the present invention as follows:

A kind of swelling fixture being applicable to black skin, comprise ring flange, be fixed on the axle at ring flange center, by the retainer that bolt is connected with ring flange, described retainer is evenly equipped with multiple slide block along the circumferential direction, and slide block is fixed with cushion block, taper expansion set is also provided with between retainer and axle, taper expansion set and slide block compact siro spinning technology, be connected with spring between taper expansion set front end and ring flange, and taper expansion set end is provided with the clamp nut be set in axle.

Be provided with bonnet between described taper expansion set and clamp nut, bonnet is fixed by screws in taper expansion set end, and advantage is convenient to extrude taper expansion set when clamp nut is fastening, and bonnet can protect taper expansion set, prevents its fastened nut crimp so that damages.

Described slide block is provided with three pieces, is fixedly connected with between slide block with cushion block by screw, and advantage is that three pieces of slide blocks can press closer workpiece; prevent it from loosening; save time and cost, cushion block is used for the sealing function between slide block and workpiece, also plays the effect of protection surface of the work simultaneously.

The tapering of described taper expansion set agrees with mutually with the gradient of slide block bottom surface, and advantage extruding taper expansion set while, can make slide block axially-movable.

Described axle and clamp nut junction are provided with screw thread, and advantage is convenient to clamp nut screw.

Have employed above-mentioned scheme, fixing by being welded to connect between axle and ring flange, can ensure that axle is to the perpendicularity of ring flange and axiality like this, slide block is arranged on retainer, retainer grip slide, make it axial restraint, slide block lower end is agreed with mutually with taper expansion set, slide block radial motion can be made like this by the axially-movable of taper expansion set, the clamp nut extruding taper expansion set be provided with by live spindle, its axially-movable can be made, the spring that taper expansion set front end is arranged can after process finishing, to outward winding clamp nut, taper expansion set is pushed open reset by the elastic force of spring, slide block is separated with workpiece, so just part can be pulled down, structure is simple, in addition for the workpiece that processing internal diameter is different, can by changing the cushion block of different size.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

In accompanying drawing, 1 is ring flange, and 2 is axle, and 3 is retainer, and 4 is slide block, and 5 is cushion block, and 6 is taper expansion set, and 7 is clamp nut, and 8 is bonnet, and 9 is screw thread, and 10 is spring.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is further described.

As Fig. 1, a kind of swelling fixture being applicable to black skin, comprise ring flange 1, be fixed on the axle 2 at ring flange 1 center, by the retainer 3 that bolt is connected with ring flange 1, described retainer 3 is evenly equipped with multiple slide block 4 along the circumferential direction, slide block 4 is fixed with cushion block 5, taper expansion set 6 is also provided with between retainer 3 and axle 2, taper expansion set 6 and slide block 4 compact siro spinning technology, be connected with spring 10 between taper expansion set 6 front end and ring flange 1, taper expansion set 6 end is provided with the clamp nut 7 be set in axle 2.

Bonnet 8 is provided with between described taper expansion set 6 and clamp nut 7; bonnet 8 is fixed by screws in taper expansion set 6 end; advantage is convenient to extrude taper expansion set 6 when clamp nut 7 is fastening, and bonnet 8 can protect taper expansion set 6, prevents its fastened nut 7 crimp so that damages.

Described slide block 4 is provided with three pieces; be fixedly connected with by screw between slide block 4 with cushion block 5; advantage is that three pieces of slide blocks can press closer workpiece; prevent it from loosening; save time and cost; cushion block is used for the sealing function between slide block and workpiece, also plays the effect of protection surface of the work simultaneously, can change different cushion blocks in addition to clamp different workpiece.

The tapering of described taper expansion set 6 agrees with mutually with the gradient of slide block 4 bottom surface, and advantage extruding taper expansion set while, can make slide block axially-movable.

Described axle 2 is provided with screw thread 9 with clamp nut 7 junction, and advantage is convenient to clamp nut 7 screw.
