Abstract
The invention relates to a hooping rounding tool for a thin-walled part. The tool comprises an outer sleeve 1, an inner sleeve 2 and bolts 3. The outer sleeve 1 is matched with the inner sleeve 2 in a threaded way. The bolts 3 with the same parameters are circumferentially and uniformly distributed on the inner sleeve 2. Splines are arranged at positions, contacting with the outer sleeve, of the bolts. Saw-teeth are arranged on the end part of the outer sleeve 1. The number of the saw-teeth is the same as that of the bolts 3. Inclination angles of the saw-teeth are the same as lead angles of the outer sleeve 1. When the outer sleeve rotates, the saw-teeth can be simultaneously joined with the splines, so that each fastening bolt can be uniformly screwed in or screwed out to realize synchronous screwing-in or screwing-out to uniformly hoop an external diameter and an internal diameter within a certain size range; and the tool has the advantages of simplicity in operation, high efficiency and no influence of a thickness difference of the part.
Description
Technical field
The present invention relates to a kind of hoop sired results tool, especially a kind of 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.
Summary of the invention
The purpose of this invention is to provide a kind of hoop sired results tool, not only can realize the even hoop circle to the inside and outside footpath of thin-wall construction part, have simultaneously simple to operate, efficient is high, be not subjected to the impact of part Wall-Thickness Difference.
Technical scheme of the present invention is; thin-wall construction part hoop sired results tool comprises outer sleeve 1, inner sleeve 2, bolt 3; be threaded engagement between described outer sleeve 1 and the inner sleeve 2; on inner sleeve 2 along the identical bolt 3 of circumferential uniform parameter; the position that contacts with outer sleeve on the described bolt 3 is provided with spline; the end of outer sleeve 1 is provided with sawtooth, and described sawtooth number is identical with bolt 3 numbers, and the inclination angle of sawtooth is identical with the lead angle of outer sleeve 1.Described screw thread 3 is 12.
The present invention is by at the outer sleeve setting sawtooth identical with the number of bolts of installing with sleeve, be provided with spline on the bolt, can realize when the rotary sleeve cylinder, simultaneously interlock of sawtooth spline, because the inclination angle of outer sleeve sawtooth is identical with the lead angle of inner bolt, 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, realize 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.The present invention can realize the even banding to external diameter and internal diameter in the certain size scope; Can realize different banding speed by regulating the individual component size; Have advantages of simple to operate, efficient is high and be not subjected to the impact of part Wall-Thickness Difference.

The specific embodiment
As shown in the figure; thin-wall construction part hoop sired results tool comprises outer sleeve 1, inner sleeve 2, bolt 3; be threaded engagement between described outer sleeve 1 and the inner sleeve 2; on inner sleeve 2 along the identical bolt 3 of circumferential uniform parameter; the position that contacts with outer sleeve on the described bolt 3 is provided with spline; the end of outer sleeve 1 is provided with sawtooth, and described sawtooth number is identical with bolt 3 numbers, and the inclination angle of sawtooth is identical with the lead angle of outer sleeve 1.Described screw thread 3 is 12.
Claims (2)
1. the hoop sired results tool of a thin-walled parts, it is characterized in that, described instrument comprises outer sleeve [1], inner sleeve [2], bolt [3], be threaded engagement between described outer sleeve [1] and the inner sleeve [2], upper along the identical bolt [3] of circumferential uniform parameter at inner sleeve [2], the upper position that contacts with outer sleeve of described bolt [3] is provided with spline, the end of outer sleeve [1] is provided with sawtooth, described sawtooth number is identical with bolt [3] number, and the inclination angle of sawtooth is identical with the lead angle of outer sleeve [1].
