Abstract
The present invention relates to one kind to bind round circle device, including outer sleeve, inner sleeve, bolt, described outer sleeve and inner sleeve are cup-like structure, outer sleeve is enclosed on inner sleeve and coordinated for gap, parameter identical bolt is evenly distributed on inner sleeve, the position contacted on bolt with outer sleeve is provided with spline, the end set of outer sleeve has sawtooth, slideway is additionally provided with outer sleeve, the sliding block installed in inner sleeve is provided with slideway, the angle of described slideway circumferentially is identical with the inclination angle of sawtooth.The present invention in outer sleeve by setting and with the number of bolts identical sawtooth installed on sleeve, spline is provided with bolt, by being exerted a force to reinforcing screw thread, relatively move outer sleeve, realize for needing slow banding or needing the hoop of the larger thin-wall construction part of tightening force to justify, the advantages of there is simple to operate, efficiency high and do not influenceed by part Wall-Thickness Difference.
Description
Technical field
The present invention relates to one kind to bind round circle device.
Background technology
In machining, many thin-wall tube-shaped parts need to bind round circle in processing, measurement.Hoop sired results dress is equal mostly at present
It cannot be guaranteed that from circumference uniform throughout banding part, even if there is the instrument of uniform banding, and uniformly supportted greatly by cone match
The endoporus of part, and can not realize and hoop circle is carried out to external diameter.Justify for the hoop of external diameter, the instrument of generally use is as shown in figure 1, logical
Cross on the larger becket of rigidity, radially even setting fastening bolt, while turning fastening bolt, measure thin-wall construction
The internal diameter of part is justified to determine whether shaft tube is bound round, and not only complex operation, efficiency are low and by part wall thickness for this hoop circle method
The influence of difference, in the case where part Wall-Thickness Difference is larger, measurement internal diameter circularity not can prove that whether its external diameter is justified by hoop.
The content of the invention
It is an object of the invention to provide one kind to bind round circle device, can not only realize to the inside and outside footpath of thin-wall construction part
Uniformly hoop circle, while there is simple to operate, efficiency high, do not influenceed by part Wall-Thickness Difference.
The technical scheme is that hoop circle device includes outer sleeve, inner sleeve, bolt, described outer sleeve and inner sleeve
Cylinder is cup-like structure, and outer sleeve is enclosed on inner sleeve and coordinated for gap, and bottom is by reinforcing bolt connection, the edge on inner sleeve
Circumferential uniform parameter identical bolt, the position contacted with outer sleeve on described bolt are provided with spline, the end of outer sleeve
Sawtooth is provided with, described sawtooth number is identical with number of bolts, and slideway is additionally provided with outer sleeve, peace is provided with slideway
Mounted in the sliding block of inner sleeve, the angle of described slideway circumferentially is identical with the inclination angle of sawtooth.Described slideway is uniform 3
At~4, described screw thread is 12.
The present invention in outer sleeve by setting with the number of bolts identical sawtooth installed on sleeve, being provided with bolt
Spline, by being exerted a force to reinforcing screw thread, relatively move outer sleeve, it is possible to achieve sawtooth is engaged spline simultaneously, due to overcoat barrel saw
Angle of the inclination angle of tooth with slideway circumferentially is identical, it is ensured that in the range of certain angle, outer sleeve sawtooth and fastening bolt
Spline engages everywhere, ensures bolt synchronous rotation, will not both separate or will not be stuck, so that each fastening bolt is equably screwed into
Or back-out, realize synchronous precession or back-out.Before use, the precision setting of the outline of all bolt ends or Internal periphery is high
Required in by the circularity of the thin-wall construction part of hoop circle, when in use, in the case where bolt synchronous rotates, it is possible to ensure institute
There are the outline of bolt or the precision of Internal periphery, the hoop of thin-wall construction part internal diameter or external diameter is justified so as to realize.Pass through setting
Screw thread is reinforced, is realized for needing slow banding or needing the hoop of the larger thin-wall construction part of tightening force to justify.The present invention can
Realized in the range of certain size to external diameter and the uniform banding of internal diameter；Different hoops can be realized by adjusting individual part size
Tight speed；The advantages of not influenceed with simple to operate, efficiency high and by part Wall-Thickness Difference.
Brief description of the drawings
Fig. 1 is existing hoop circle structural representation；
Fig. 2 is the structural representation of the present invention；
Fig. 3 is the profile of the present invention.
Embodiment
As illustrated, hoop circle device includes outer sleeve 1, inner sleeve 2, bolt 3, described outer sleeve 1 and inner sleeve 2 are cup
Shape structure, outer sleeve 1 are enclosed on inner sleeve 2 and coordinated for gap, and bottom is connected by reinforcing bolt 4, along week on inner sleeve 2
To uniform parameter identical bolt 3, the position contacted on described bolt 3 with outer sleeve is provided with spline, the end of outer sleeve 1
Sawtooth is provided with, described sawtooth number is identical with the number of bolt 3, and slideway 5 is additionally provided with outer sleeve 1, is set in slideway 5
There is a sliding block 6 installed in inner sleeve 2, the angle of described slideway circumferentially is identical with the inclination angle of sawtooth.Described slideway is
At uniform 3~4, described screw thread 3 is 12.
