Abstract
The invention discloses a clamping and fixing device for a thin-walled cylindrical part. The clamping and fixing device comprises a cylindrical sleeve, wherein a base is arranged at the lower part of the cylindrical sleeve; a circular lug boss connected with a lathe spindle is formed at the lower part of the base; a stepped hole connected with a lathe flange plate is formed in the base; an internal thread connected with the outer peripheral surface of the cylindrical part is formed in the upper part on the inner peripheral surface of the central hole in the sleeve; a threaded hole perpendicular to the central hole is formed below the internal thread in the sleeve; a locking jackscrew is connected into the threaded hole; a bolt is connected into the locking jackscrew after penetrating a gasket and a fan-shaped pressing plate matched with the inner side wall of the sleeve. When the clamping and fixing device is used for clamping the part on a lathe, the internal thread in the inner peripheral surface of the sleeve is used for clamping and fixing the outer peripheral surface of the cylindrical part, and the bolt is fixed in the locking jackscrew after penetrating the gasket and the fan-shaped pressing plate, so that the lower part on the inner peripheral surface of the cylindrical part is fixed with the internal thread of the sleeve again. Therefore, the problem that in the prior art, part deformation is caused easily when the cylindrical part is fixed on the lathe with a three-jaw chuck is solved.
Description
Technical field
The invention belongs to a kind of clamping fixer, be specifically related to a kind of clamping fixer of thin-walled tube kind part.
Background technology
In Vehicle Processing process, often need thin-walled tube kind part scroll chuck to be fixed on lathe, because the rigidity of thin-walled tube kind part is poor, when carrying out parts fixation, the scroll chuck of engine lathe is easy to the sidewall extrusion of part to be out of shape, thus causes part rejection.
Summary of the invention
The present invention proposes to overcome the shortcoming existed in prior art, its objective is the clamping fixer providing a kind of thin-walled tube kind part.
The present invention realizes by following technical scheme:
A kind of clamping fixer of thin-walled tube kind part, comprise the cylindrical sleeve that bottom has base, the round boss be connected with machine tool chief axis is formed at base bottom, base is formed the shoulder hole be connected with lathe ring flange, the internal thread be connected with cylindrical part outer peripheral face is formed at the centre bore inner peripheral surface top of sleeve, the screwed hole vertical with centre bore is formed at the internal thread bottom of sleeve, locking jackscrew is connected in screwed hole, and bolt is connected to locks in jackscrew through packing ring, the fan-shaped pressing plate that matches with sleeve madial wall.
Described screwed hole is along uniform three of sleeve internal perisporium.
Described shoulder hole is six uniform along base outer perimeter face.
The present invention of such design, the round boss of base bottom is connected with machine tool chief axis, shoulder hole on base is connected with lathe ring flange, whole device is fixed, the outer peripheral face of cylindrical part is threaded in the internal thread place of bushing core hole inner peripheral surface, bolt is through packing ring simultaneously, fan-shaped pressing plate is connected in the locking jackscrew of screwed hole, respectively the outer peripheral face of cylindrical part and inner peripheral surface are fixed, overcome in prior art, directly by cylindrical part clamping on the scroll chuck of lathe time, cylindrical part is easily caused to be out of shape, thus the shortcoming causing cylindrical part to be scrapped.Novel structure of the present invention, simple installation, reduces product rejection probability, has saved cost.

Detailed description of the invention
Below, be described in detail with reference to the clamping fixer of drawings and Examples to thin-walled tube kind part of the present invention.
As shown in Figures 1 to 3, a kind of clamping fixer of thin-walled tube kind part, comprise the cylindrical sleeve 1 that bottom has base 2, the round boss 3 be connected with machine tool chief axis is formed at base 2 bottom, base 2 is formed the shoulder hole 2a be connected with lathe ring flange, the internal thread be connected with cylindrical part 4 outer peripheral face is formed at the centre bore 1a inner peripheral surface top of sleeve 1, the screwed hole 1b vertical with centre bore 1a is formed at the internal thread bottom of sleeve 1, locking jackscrew 5 is connected in screwed hole 1b, bolt 6 is through packing ring 7, the fan-shaped pressing plate 8 matched with sleeve 1 madial wall is connected to locks in jackscrew 5.
Described bolt 6 is hexagon socket head cap screw.
Described screwed hole 1b is along uniform three of sleeve 1 internal perisporium, and in order to make the clamping of cylindrical part 4 more firm, screwed hole 1b also can be designed as more than three.
Described shoulder hole 2a is along uniform six of base 2 outer peripheral face.
Using method of the present invention is as follows:
First, be connected and fixed with the main shaft of lathe by the round boss 3 of this device pedestal 2 bottom, screw is connected with the ring flange of lathe through the shoulder hole 2a on base 2; Then, the outer peripheral face of cylindrical part 4 is connected to the internal thread place of sleeve 1, the outer peripheral face of cylindrical part 4 is fixed, bolt 6 is connected in the locking jackscrew 5 of screwed hole 1b through packing ring 7, fan-shaped pressing plate 8, fan-shaped pressing plate 8 is made to compress the inner peripheral surface bottom of cylindrical part 4, be fixed the inner peripheral surface of cylindrical part 4, the clamping that now can complete cylindrical part 4 is fixed.
Round boss is fixed on machine tool chief axis by the present invention, shoulder hole on base is connected with the ring flange of lathe, whole device is made to be fixed on lathe, cylindrical part is connected in the centre bore of sleeve, bolt is fixed in locking jackscrew through pad, fan-shaped pressing plate, respectively the outer peripheral face of cylindrical part, inner peripheral surface are fixed, clamping effect is more firm, avoid in use procedure and cause loosening of part, overcome in prior art, during Vehicle Processing employing clamping with three-jaw chuck cylindrical part, easily cause the shortcoming of part deformation.Apparatus design of the present invention is simple, and clamping parts is firm.
