Abstract
The invention provides a device for measuring parallelism of buses with two rotary bodies. The measuring device comprises a guide rail, a sliding block, an index sleeve, a soft rope, a limiting block, a pressing piece, screws and displacement sensors. The limiting block comprises two 120-degree V-shaped faces and a 60-degree V-shaped face, two non-contact displacement sensors are fixed on the 120-degree V-shaped faces respectively, the pressing piece comprises a 60-degree V-shaped face which is provided with the screws in a fastening mode, the screwing depth of the screws are adjusted to change the angle of the 120-degree V-shaped faces of the limiting block, and therefore attaching gaps between the limiting block and the rotary bodies are adjusted. The soft rope is connected with the limiting block and the sliding block, the index sleeve rotates to drive the limiting block to move along the gap between the two rotary bodies, the displacement sensors measure and display parallelism or distance of two buses, and the measuring precision is smaller than 1 micron.
Description
Technical field
The invention belongs to geometric measurement field, be specifically related to a kind of two solid of revolution bus parallelism measuring apparatus.
Background technology
Two parallel solid of revolution (as right cylinder) that spacing is less, two depth of parallelisms that need to measure its bus, tested bus annex is that requirement can not have wearing and tearing simultaneously.Normally milscale is measured the external diameter distance of two solid of revolution, then deducts the diameter dimension of solid of revolution.From dimension chain, for spot measurement, the diameter error that this measurement result has comprised solid of revolution, for multimetering, this result also includes the shape error of solid of revolution, so bus measurement of paralleism precision is not high.For improving measuring accuracy, need to shorten dimension chain, reduce and measure intermediate link, be necessary to measure from solid of revolution gap location the depth of parallelism of two buses.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of two solid of revolution bus parallelism measuring apparatus.
Two solid of revolution bus parallelism measuring apparatus of the present invention, contain guide rail, slide block, index sleeve, tightrope, limited block, compressing tablet, screw, displacement transducer, on limited block, be fixed with two non-contact displacement sensors, compressing tablet by screw fastening to limited block, tightrope connects limited block and slide block, index sleeve rotates, and drives limited block to move along two solid of revolution gaps, and displacement sensor also shows the two bus depth of parallelism or distances.
Described limited block (5) has two symmetrical 120 ° of V faces and 60 ° of V faces, and compressing tablet also has 60 ° of V faces, regulates the fixedly degree of tightness of the screw of compressing tablet, for adjusting the subtended angle size of two 120 ° of V faces on limited block.
Described limited block is hung by tightrope, between two solid of revolution.
Two solid of revolution bus parallelism measuring apparatus of the present invention, are used for, from the depth of parallelism of internal measurement two space bar buses, containing guide rail, slide block, index sleeve, tightrope, limited block, compressing tablet, screw, displacement transducer.Described limited block is a frock with two 120 ° of V faces and one 60 ° V face structures, two 120 ° V face structural symmetry.Described compressing tablet also has the V face of 60 °, and 60 ° of V face laminatings with described limited block, are fixed on described limited block by screw, and the degree of tightness of set screw, can regulate the position of compressing tablet in limited block, and then 120 ° of subtended angles of fine setting.In the middle of 120 ° of V faces, each fixes a described displacement transducer (electric capacity or eddy displacement sensor), and tightrope is fixed on limited block end face.Described limited block is vertically placed in the middle of two space solid of revolution, rotated described index sleeve, limited block moves between two solid of revolution, and the depth of parallelism of described displacement sensor solid of revolution bus, realizes high precision, the non-contacting depth of parallelism or range observation.

Embodiment
Below in conjunction with accompanying drawing, parallelism measuring apparatus of the present invention is elaborated.
Fig. 1 is the schematic diagram of measurement mechanism of the present invention, and Fig. 2 is the sectional view of Fig. 1.As can be seen from the figure, two solid of revolution bus parallelism measuring apparatus of the present invention are put into described compressing tablet 6 in 60 ° of V faces of described limited block 5, adjust the degree of tightness of screw 7, change the depth location of compressing tablet 6, thereby the subtended angle of two 120 ° of V faces on adjustment limited block, limited block 5 is put into the gap of two solid of revolution, check the laminating situation of V face and solid of revolution, if gap is larger, further adjust the degree of depth of screw 7, until the gap between binding face is less than 0.01mm, while now described limited block 5 being put into two solid of revolution inside, it can free-falling and is clog-free, also without obviously rocking.Adjust after the V face of limited block 5, with tightrope 4, connect limited block 5 and slide block 2, rotate index sleeve 3, guide rail 1 promotes slide block 2 and moves, limited block 5 moves along bus in solid of revolution gap, described displacement transducer 8 is measured and display measurement result, and measuring accuracy is less than 1 μ m, also can calculate the depth of parallelism by special measurement software.
Be understandable that, those skilled in the art also can do other based on spirit of the present invention and change to apply in other respects, as long as it does not depart from technique effect of the present invention.These variations of doing according to spirit of the present invention all should be considered as in the present invention's scope required for protection.
