Abstract
The invention provides a multi-section hooping tool for parts in thin-walled structures. The multi-section hooping tool comprises an outer sleeve, an inner sleeve and bolts, wherein the outer sleeve and the inner sleeve are in cup-shaped structures; the outer sleeve is sleeved on the inner sleeve and is in clearance fit therewith; the same number of bolts with the same parameters are evenly distributed on the inner sleeve along multiple axial sections; saw teeth are arranged on the end surfaces and a through slot of the outer sleeve; splines are arranged in the positions on the bolts, which are contacted with the outer sleeve; and slideways are additionally arranged on the outer sleeve. The multi-section hooping tool has the advantages that through arranging the saw teeth on the outer sleeve, arranging the splines on the bolts and applying force to stressing threads to relatively move the outer sleeve, the saw teeth can be simultaneously occluded with the splines and synchronous screwing or unscrewing is realized; and since the bolts are arranged on the multiple sections of the large inner sleeve, the multiple sections can be simultaneously and tightly hooped and the diameters of the sections can be enabled to be the same, so simultaneous hooping of the multiple sections is further realized.
Description
Technical field
The present invention relates to a kind of hoop sired results tool, especially a kind of multi-section hoop sired results tool of thin-wall construction part.
Background technology
In machining, a lot of thin-wall tube-shaped parts need bind round circle when processing, measurement.At present mostly hoop sired results dress all can not guarantee from circumference even banding part everywhere, even the instrument of even banding is arranged, also is by the even endoporus of the large part of support of cone match, and can't realizes external diameter is bound round circle.Hoop circle for external diameter, usually the instrument that adopts as shown in Figure 1, by on the larger becket of rigidity, fastening bolt radially evenly is set, when turning fastening bolt, measure the internal diameter of thin-wall construction part and determine whether shaft tube is justified by hoop, this hoop circle method not only complicated operation, efficient is low and be subjected to the impact of part Wall-Thickness Difference, in the situation that the part Wall-Thickness Difference is larger, measures internal diameter circularity and can not prove that whether its external diameter is by the hoop circle.Simultaneously, this structure can only be bound round circle to a cross section, can not bind round circle to a plurality of cross sections simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of hoop sired results tool, not only have simple to operate, efficient is high, be not subjected to the characteristics of the impact of part Wall-Thickness Difference, and can realize circle is evenly bound round in a plurality of cross sections in the inside and outside footpath of thin-wall construction part simultaneously.
Technical scheme of the present invention is; the multi-section hoop sired results tool of thin-wall construction part comprises outer sleeve; inner sleeve; bolt; described outer sleeve and inner sleeve are cup-like structure; outer sleeve is enclosed within on the inner sleeve and is matched in clearance; the bottom connects by afterburning bolt; at the equal identical bolt of uniform quantity and parameter on a plurality of cross sections vertically on the inner sleeve; the bolt on the distance cup cross section farthest, the end and the end contact of outer sleeve; other bolt passes the groove that arranges on the outer sleeve; the end face at outer sleeve is provided with sawtooth; the number of sawtooth is identical with the number of bolt; be provided with the sawtooth identical with end face and contact with bolt at groove; the position that contacts with outer sleeve on the described bolt is provided with spline; also be provided with slideway on outer sleeve; be provided with the slide block that is installed in inner sleeve in the slideway, and described slideway is identical with the inclination angle of sawtooth along circumferential angle.Described slideway is 3～4 uniform places, and described axial cross section is 3, and the bolt in every cross section is 12.
The number of bolts identical sawtooth of the present invention by installing at outer sleeve setting and inner sleeve, be provided with spline on the bolt, by to the afterburning screw thread application of force, outer sleeve relatively moves, can realize simultaneously interlock of sawtooth spline, because the inclination angle of outer sleeve sawtooth is identical along circumferential angle with slideway, can guarantee in the certain angle scope, outer sleeve sawtooth and fastening bolt spline mesh everywhere, the rotation of assurance bolt synchronous, neither can separate can be not stuck yet, thereby each fastening bolt is screwed into equably or back-outs, and realizes synchronous precession or back-out.Before use, the outline of all bolt ends or the precision setting of interior profile are higher than by the circularity requirement of the thin-wall construction part of hoop circle, in use, in the situation that bolt synchronous rotation, just can guarantee the precision of outline or the interior profile of all bolts, thereby realize the hoop circle to thin-wall construction part internal diameter or external diameter, have advantages of simple to operate, efficient is high and be not subjected to the impact of part Wall-Thickness Difference.On a plurality of cross sections of large inner sleeve bolt is set, can carries out banding and can guarantee that each diameter of section is identical a plurality of cross sections simultaneously, and then hoop circle when having realized multi-section.
