Limited block has two 120 �� of V faces and 60 �� of V faces, 120 �� of V faces are fixed with two non-contact displacement sensors respectively, compressing tablet has 60 �� of V faces, by screw fastening on 60 �� of V faces of limited block, set screw be screwed into the depth, 120 �� of V face angles of limited block can be changed, thus adjust the laminating gap of limited block and solid of revolution, tightrope connects limited block and slide block, calibration cylinder rotates, driving limited block to move along two solid of revolution gaps, displacement sensor also shows two bus parallelism or distances, and measuring accuracy is less than 1 ��m.
Description
Technical field
The invention belongs to geometry measurement field, it is specifically related to a kind of two solid of revolution bus parallelism measuring apparatus.
Background technology
The parallel solid of revolution (such as right cylinder) that two spacing are less, two need the parallelism measuring its bus, and tested bus annex is that requirement can not have abrasion simultaneously. Normally the external diameter distance of two solid of revolution measured by milscale, then subtracts the diameter size of solid of revolution. By size chain it will be seen that for spot measurement, this measuring result contains the diameter error of solid of revolution, for multimetering, the shape error of solid of revolution is also comprised into by this result, and therefore bus measurement of paralleism precision is not high. For improving measuring accuracy, it is necessary to shorten size chain, reduce and measure middle-chain, it is necessary to measure the parallelism of two buses from solid of revolution gap location.
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.
The two solid of revolution bus parallelism measuring apparatus of the present invention, containing guide rail, slide block, calibration cylinder, tightrope, limited block, compressing tablet, screw, displacement sensor, limited block is fixed with two non-contact displacement sensors, compressing tablet by screw fastening on limited block, tightrope connects limited block and slide block, calibration cylinder rotates, and drives limited block to move along two solid of revolution gaps, and displacement sensor also shows two bus parallelism or distances.
Described limited block (5) has V face, two symmetrical 120 �� and 60 �� of V faces, and compressing tablet also has 60 �� of V faces, regulates the degree of tightness of the screw of fixing compressing tablet, for the subtended angle size in two 120 �� of V faces adjusted on limited block.
Described limited block is hung by tightrope, between two solid of revolution.
The two solid of revolution bus parallelism measuring apparatus of the present invention, are used for the parallelism from internal measurement two space bar bus, containing guide rail, slide block, calibration cylinder, tightrope, limited block, compressing tablet, screw, displacement sensor. Described limited block is a frock with two 120 �� of V faces and one 60 �� V face structures, two 120 �� V face symmetrical configuration. Described compressing tablet also has the V face of 60 ��, with the 60 of described limited block �� of V face laminatings, is fixed on described limited block by screw, the degree of tightness of set screw, it is possible to regulate the position of compressing tablet in limited block, and then fine setting 120 �� of subtended angles. Each in the middle of 120 �� of V faces fixing institute's displacement sensors (electric capacity or eddy displacement sensor), tightrope is fixed on limited block end face. Vertically being placed in the middle of two space solid of revolution by described limited block, rotate described calibration cylinder, limited block moves between two solid of revolution, the parallelism of described displacement sensor solid of revolution bus, it is achieved high precision, non-contacting parallelism or range observation.

Embodiment
Below in conjunction with accompanying drawing, the parallelism measuring apparatus of the present invention is done explanation in detail.
Fig. 1 is the schematic diagram of the measuring apparatus of the present invention, and Fig. 2 is the sectional view of Fig. 1. As can be seen from the figure, the two solid of revolution bus parallelism measuring apparatus of the present invention contain calibration cylinder 1, guide rail 2, slide block 3, tightrope 4, limited block 5, compressing tablet 6, screw 7, displacement sensor 8; Described calibration cylinder 1 is connected with guide rail 2, and slide block 3 is connected with guide rail 2; Being fixed with two non-contact displacement sensors 8 on described limited block 5, compressing tablet 6 is fastened on limited block 5 by screw 7; Tightrope 4 connects limited block 5 and slide block 3 respectively; Calibration cylinder 1 rotates, and slide block 3 moves on guide rail 2, and tightrope 4 drives limited block 5 to move along two solid of revolution gaps, and displacement sensor 8 is measured and shown two bus parallelism or distances.
Described compressing tablet 6 is put in 60 �� of V faces of described limited block 5 by the two solid of revolution bus parallelism measuring apparatus of the present invention, the degree of tightness of adjustment screw 7, change the depth location of compressing tablet 6, thus adjust the subtended angle in two 120 �� of V faces on 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 bigger, then adjust the degree of depth of screw 7 further, until the gap between binding face is less than 0.01mm, now described limited block 5 is put into two solid of revolution inner time, it can free-falling and clog-free, also without obviously rocking. After adjusting the V face of limited block 5, limited block 5 and slide block 3 is connected with tightrope 4, rotate calibration cylinder 1, guide rail 2 promotes slide block 3 to move, limited block 5 moves along bus in solid of revolution gap, described displacement sensor 8 is measured and display measurement result, and measuring accuracy is less than 1 ��m, it is possible to by special measurement computed in software parallelism.
It should be appreciated that those skilled in the art also can do other change to apply in other respects based on spirit of the present invention, as long as it does not deviate the technique effect of the present invention. These changes done according to the present invention's spirit all should be considered as in the claimed scope of the present invention.
