Summary of the invention:
The object of the invention is to: providing a kind of compact conformation for overcoming the above problems, solving the integration problem of inner conical surface position measurement and other dimension measuring device, and there is measuring accuracy, the inner conical surface position measurement mechanism of easy to use, low cost of manufacture.
The technical solution adopted in the present invention is such:
A kind of inner conical surface position measurement mechanism, comprise fixed support, rotate compressing lever, reed in slow, is placed in the compressing screw contact on lever, the attachment screw of connection bracket and lever, and the abutment sleeve be placed on fixed support, the scalable torsion screw of the band measuring head in sleeve, connects flexible torsion screw and the nut of Compress Spring, and reverses the guider screw of guiding for reversing screw.
Further, described fixed support bottom design has two screw holes, can conveniently be fixed on pedestal, and support one end has one vertically to fix small rack, and conveniently can fix and rotate compressing lever, the other end is provided with an endoporus simultaneously.
Further, described rotation compressing lever left end is fixed on support, and screw contact suffers oppression and causes lever to turn clockwise, one end of lever like this again by while compression band measuring head scalable torsion screw, make to suffer oppression point, pressure point and fulcrum forms leverage and amplifies its stroke, make measuring head can with measured taper-face contact.
Further, described spring housing is outside at the scalable torsion screw of band measuring head, and tightens with nut, pad, and spring is in compressive state, to ensure that the flexible screw that reverses stretches out all the time.A buffering reed is secured in the scalable torsion screw upper end of band measuring head.
Further, the scalable torsion screw axial of described band measuring head has helicla flute, is provided with a fixing screw inside abutment sleeve.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows: this invention structure is simple, compact, it takes full advantage of the action of testee in installation process, and automatically complete the installation of inner conical surface position, measuring accuracy is high, easy to use, low cost of manufacture.

Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the specific embodiment of the invention further below.
As shown in Figure 1, 2, this invention inner conical surface measuring mechanism, comprise fixed support, rotate compressing lever, be placed in the compressing screw contact on lever, the attachment screw of connection bracket and lever, and the abutment sleeve be placed on fixed support, the scalable torsion screw of the band measuring head in sleeve, connects flexible torsion screw and the nut of Compress Spring, and reverses the guider screw of guiding for reversing screw.
Fixed support is locked on pedestal, with attachment screw locking lever one end on support, adjustment screw degree of tightness, require that lever can rotate freely, lever both sides are provided with expansion screw as stressed pressure point, and abutment sleeve is embedded on support, and spring housing is outside sleeve simultaneously, scalable torsion screw with measuring head is built in sleeve and spring, tightens with nut and pad.
The scalable torsion screw (as shown in Figure 4) of critical component band measuring head of the present invention, free state remains on extreme higher position under spring action, when being stressed, while its compression displacement of precise hard_drawn tuhes, rotate depression bar rotation 90 °, Telescopic rotary depression bar like this then can detect measured piece inner conical surface, must ensure the scalable freedom of torsionspring in installation process, can first test its elasticity, then be adjusted.
For the position measurement of 30 °, HSK63 handle of a knife clamping inner conical surface, carry out concrete operations explanation.30 ° of clamping inner conical surface positional values of master gauge are 18.13mm.Measuring process is as follows:
(1) demarcate.Master gauge is placed in apparatus of the present invention, displacement sensor head is contacted with measuring head 7 lower surface of scalable torsion screw of the present invention, and displacement transducer initial value is set to 0.
(2) measure.Measured body is placed in apparatus of the present invention, writes down the indicated value of displacement sensor, be assumed to be 0.042.
(3) calculate.At this moment, the positional value of measured body inner conical surface is 18.13+0.042=18.172mm.
During operation, the present invention is placed in comparatively on finishing operations table top, as shown in Figure 3, UUT is placed in apparatus of the present invention, using base reference plane as the first benchmark, ensure to be measured outer datum end face and the first benchmark exact contact (marking in figure shown in 11), meanwhile to be measured interior datum end face is by the compressing screw (marking shown in 12 in figure) on compressing lever, make it to rotate compressing and reverse screw, torsion screw and Compress Spring together shrink decline, and reverse screw rotation 90 °, the measuring head of rotary screw lower end is then with to contact with to be measured inner conical surface (marking in figure shown in 13), its position is determined by the displacement transducer of lower surface, obtain inner conical surface measuring position to be measured data.The inner conical surface positional value of this measurement being met with master gauge compares, and can facilitate, obtain accurately the particular location value of inner conical surface to be measured measurement.
More than illustrate and describe ultimate principle of the present invention and principal character and at us from the application of grinding in project.The technician of the industry should understand; the present invention is not by the restriction of above-mentioned example; what describe in above-mentioned example and instructions merely illustrates ultimate principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all should fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
