Abstract
The utility model relates to a thin-wall bipyramid concentric tension tool, which is composed of a double -taper inclined wedge, an elastic tension sleeve of inner thin wall and an elastic tension sleeve of outer thin wall. An inner cone is arranged on the inside of the elastic tension sleeve of out thin wall; an outer cone is arranged on the outside of the elastic tension sleeve of inner thin wall. The double -taper inclined wedge is arranged between the elastic tension sleeve of out thin wall and the elastic tension sleeve of inner thin wall. The cone between the double -taper inclined wedge and elastic tension sleeve of outer thin wall touches with each other and is connected by a long bolt which passes through the elastic tension sleeve of inner thin wall. The cone between the double -taper inclined wedge and elastic tension sleeve of inner thin wall touches with each other and is directly connected with a short bolt. A changeable clearance is remained between the elastic tension sleeve of outer thin wall and the elastic tension sleeve of inner thin wall, as well as between the elastic tension sleeve of inner thin wall and the double -taper inclined wedge. The utility model overcomes the disadvantage of that the traditional measuring method is not comprehensive enough and the measuring precision is not high, and the utility model can ensure the veracity and repeated consistency of the measuring precision.
Description
Technical field
The utility model relates to the concentric testing tool of a kind of inside and outside circle, especially a kind of concentric testing tool of inside and outside circle that adopts the tensioner method.
Background technology
In Machine Design and matching requirements, body shell hole two bearings shelves generally all need the right alignment requirement, and more common at present measurement detection method is as follows:
First kind is to utilize false bearings and the matching used way of axle, though this measurement means is convenient, versatility is relatively good, and measuring accuracy but is not very high.Because bearing guard body shell hole adds the existence that tolerance is arranged man-hour, and the false bearings external diameter is a definite value, Gu cooperating between bearing guard body shell hole and the false bearings exists uncertain gap; False bearings itself is exactly a clearance fit with cooperating of axle in addition, and after repeatedly using, this tolerance clearance can strengthen along with the wearing and tearing of false bearings and axle and strengthen, so uncertain gap adds between false bearings and the axle that the gap of progressively strengthening put on question mark for the accuracy of measuring between bearing guard body shell hole and the false bearings, in actual use, in order to remedy above-mentioned deficiency, usually adopt a plurality of false bearings, make its cylindrical and body shell hole join the gap, a plurality of axles and false bearings endoporus are joined the gap, though adopt this measure to promote measuring accuracy, the frock expense are strengthened, operate the trouble that becomes, also strengthened difficulty simultaneously to keeping.
Measure the structure that detection method generally adopts the tensioner cover for second kind, this structure has well solved uncertain gap between bearing guard body shell hole and the false bearings, but present tensioner cover can only the cylindrical tensioner, so still exist the harmful effect that progressively strengthens the gap between above-mentioned false bearings and the axle, supply a gap and also can only adopt transposing axle and tensioner cover to join the method in gap, equally also just exposed big, the complicated operation of frock expense, the shortcoming of keeping trouble thereupon.Gu this structure also only the solution of part problem.
The third measures detection method is the mode of having utilized hydraulic pressure film tensioner cover, this hydraulic pressure film tensioner cover can be realized inside and outside circle tensioner simultaneously, but this structure can not guarantee also very limited of the right alignment of inside and outside circle tensioner and its tensioner film amount of increase, can not satisfy the inspection of the bigger concentric hole of fit tolerance zone; This tool part accuracy requirement is higher in addition, and difficulty of processing assembles also cumbersome than higher.So the range of application of hydraulic pressure film tensioner cover is more limited, and its concentric measuring accuracy neither be very high.
Summary of the invention
The utility model is exactly that will to solve the test error that the concentric testing tool of existing inside and outside circle exists big, and the technical matters of test result poor repeatability provides a kind of thin-walled bicone concentric tensioner instrument.This instrument can overcome the shortcoming that traditional measurement method is comprehensive inadequately, measuring accuracy is not high, makes the accuracy of measuring accuracy and repeat consistance to be guaranteed.
The technical solution of the utility model is: the concentric tensioner instrument of a kind of thin-walled bicone, and by double tapered wedge body, interior thin-walled elastic tensioning cover, outer thin-walled elastic tensioning cover is formed.
Be provided with internal conical surface in the outer thin-walled elastic tensioning cover, the outer outer conical surface that is provided with of interior thin-walled elastic tensioning cover;
Be equipped with double tapered wedge cone between outer thin-walled elastic tensioning cover and the interior thin-walled elastic tensioning cover, the conical surface matches and contacts between double tapered wedge cone and the outer thin-walled elastic tensioning cover, and with passing the thru-bolt connection that interior thin-walled elastic tensioning overlaps; The conical surface matches and contacts between double tapered wedge cone and the interior thin-walled elastic tensioning cover, and directly connects with lag bolt;
Axially all leaving variable gap on the closure between outer thin-walled elastic tensioning cover and the interior thin-walled elastic tensioning cover and between interior thin-walled elastic tensioning cover and the double tapered wedge cone.
Outer thin-walled elastic tensioning cover, interior thin-walled elastic tensioning cover, the tapering on the double tapered wedge cone is 1: 20.
The outside flange of double tapered wedge cone is provided with the male screw thread that loosens that body shell with required correction concentric hole joins; Double tapered wedge cone is provided with interior thin-walled elastic tensioning cover flange joins loosens inner bolt.
The utility model adopts by double tapered wedge body, interior thin-walled elastic tensioning cover, the testing tool that outer thin-walled elastic tensioning cover is formed, inside and outside thin-walled elastic tensioning is enclosed within the amount of movement S that is equipped with certain distance on the axial direction, spurs or promotes inside and outside thin-walled elastic tensioning cover and make it realize tensioner by the effect of double tapered wedge body tapering or loosen.In use inside and outside circle all slowly tensioner until required tensioner degree, thereby improved the accuracy of measuring accuracy.
In addition, double tapered wedge body tapering was made as 1: 20, because 1: 20 tapering has self-locking performance, had guaranteed not have the phenomenon that gets loose automatically after inside and outside thin-walled elastic tensioning is enclosed within tensioner in measuring process.And inside and outside thin-walled elastic tensioning is enclosed within the maximum tensioner amount that is inside and outside thin-walled elastic tensioning cover apart from S/20 that moves axially.When inside and outside thin-walled elastic tensioning is enclosed within tensioner tensioner part tensioner is more even, thereby has guaranteed the good rigidity that contacts between this instrument and body shell hole and the axle, the accuracy of measuring accuracy and repeat consistance when also having guaranteed simultaneously to measure.
The utility model makes processing and measurement become simple owing to adopted the whole double tapered wedge cone with high precision, high rigidity with the elastomeric structure of thin-walled; The accuracy of measuring accuracy and repetition consistance are guaranteed.This instrument not only can be used for measuring, and also can be used for processing, can also expand to other field, economic benefit very obviously.
