Abstract

The invention relates to the field of machining, in particular to an expanding clamp for turning a thin-walled part. The expanding clamp comprises a flange, a core shaft is fixedly connected to the center position of the flange and is sleeved with a taper sleeve in a connected manner, one end of the taper sleeve is connected with a gland through a bolt, an adjusting nut with steps is arranged at the center position of the gland, and the adjusting nut and the core shaft are connected; an annular holder is arranged outside the taper sleeve, a certain gap is reserved between the holder and the taper sleeve, and one end of the holder is connected with the flange through a screw; and a plurality of grooves are formed in the holder, sliding blocks are arranged in the grooves, and the outer sides of the sliding blocks are connected with a workpiece through heel blocks. The expanding clamp is simple in structure and convenient to clamp, vibration is avoided during machining after clamping is carried out, the machining accuracy of the workpiece can be improved, the labor intensity of workers is reduced, and the application scope is wide.

Description

Turning thin-wall part tensioning clamper
Technical field
The present invention relates to field of machining, be specifically related to turning thin-wall part tensioning clamper.
Background technology
Thin-wall sleeve tube kind part uses widely in machinery industry, relation yet with part thickness, make clamping in part processing highly difficult, there will be that clamping is not firm or clamping makes part deformation, in production in enormous quantities, turning thin-wall sleeve part, on the one hand thin being easily deformed of workpiece wall and affect machining accuracy; Clamping part correction extremely inconvenience on the other hand, especially when endoporus is black skin, clamping is increasingly difficult. Making production efficiency low, and then increase the labor intensity of workman, business efficiency is low.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of simple in construction, convenient mounting and clamping, clamping post-treatment friction, can improve the machining accuracy of part, reduces the turning thin-wall part tensioning clamper that the work of workman is strong.
Turning thin-wall part tensioning clamper of the present invention, including ring flange, described ring flange center is fixedly connected with a mandrel, described mandrel is socketed with a tapered sleeve, tapered sleeve one end has been bolted a gland, described gland center is provided with one with the adjusting nut of step, described adjusting nut is connected with mandrel, described tapered sleeve is outside equipped with a ring-type retainer, certain interval is had between retainer and tapered sleeve, described retainer one end is connected with ring flange by screw, retainer is provided with some grooves, it is provided with slide block in described groove, it is connected with workpiece by cushion block outside described slide block.
Preferably, retainer being provided with three grooves, described groove is distributed on retainer.
Preferably, retainer being provided with four grooves, described four grooves are symmetrical between two, and between two grooves, angle is 60 ��.
Preferably, the central axis of ring flange, the central axis of retainer, mandrel central axis all on the same line.
Present configuration is simple, convenient mounting and clamping, clamping post-treatment friction, can improve the machining accuracy of part, and the work reducing workman is strong, applied widely.
Accompanying drawing explanation
Fig. 1 is turning thin-wall part tensioning clamper structural representation.
Accompanying drawing labelling: 1-ring flange, 2-mandrel, 3-retainer, 4-slide block, 5-cushion block, 6-tapered sleeve, 7-gland, 8-adjusting bolt, 9-workpiece.
Detailed description of the invention
Turning thin-wall part tensioning clamper of the present invention, including ring flange 1, described ring flange 1 center is fixedly connected with a mandrel 2, described mandrel 2 is socketed with a tapered sleeve 6, tapered sleeve 6 one end has been bolted a gland 7, described gland 7 center is provided with one with the adjusting nut 8 of step, described adjusting nut 8 is connected with mandrel 2, described tapered sleeve 6 is outside equipped with a ring-type retainer 3, certain interval is had between retainer 3 and tapered sleeve 6, described retainer 3 one end is connected with ring flange 1 by screw, retainer 3 is provided with some grooves, slide block 4 it is provided with in described groove, it is connected with workpiece 9 by cushion block 5 outside described slide block 4. being provided with three grooves on retainer 3, described groove is distributed on retainer 3. may be alternatively provided as four grooves on retainer 3, described four grooves are symmetrical between two, and between two grooves, angle is 60 ��. the central axis of ring flange 1, the central axis of retainer 3, mandrel 2 central axis all on the same line.
When fixture uses, fixing after fixture ring flange 1 is connected with lathe three-jaw driver chuck and corrects. With box spanner adjusting nut 8, make cone 6 move axially and promote slide block 4 to radially slide the purpose reaching clamping workpiece 9. During processing work 9, being unclamped by adjusting nut 8 with box spanner, gland 7 band movable cone 6 and slide block 4 move right, and make cushion block 5 move radially, then workpiece 9 can be inserted on cushion block 5. After part is inserted in, being tightened by adjusting nut 8 with box spanner, gland 7 then band movable cone 6 and slide block 4 are moved to the left, and make cushion block 5 move radially, and can be clipped by workpiece 9. Completion of processing, unclamps adjusting nut 8 with set letter spanner, can take off workpiece 9. The axial gap of 0.2mm should be stayed by gland 7 and nut shoulder place. This fixture radially adjustment amount, up to 5��10mm, can be suitable for the processing of irregular cast blank part.
