It can be seen from the dimensional chain that for single-point measurement, the measurement result includes the diameter error of the rotating body, and for multi-point measurement, the result also includes the shape error of the rotating body, so the measurement accuracy of the bus parallelism is not high.

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 [0001] The invention belongs to the field of geometric quantity measurement, and in particular relates to a device for measuring the parallelism of busbars of two revolving bodies. Background technique [0002] For two parallel rotating bodies (such as cylinders) with small spacing, the parallelism of their busbars needs to be measured for two of them, and the accessories of the busbar to be tested are required to be free from wear. Usually a micrometer is used to measure the distance between the outer diameters of the two rotating bodies, and then subtract the diameter of the rotating bodies. It can be seen from the dimensional chain that for single-point measurement, the measurement result includes the diameter error of the rotating body, and for multi-point measurement, the result also includes the shape error of the rotating body, so the measurement accuracy of the bus parallelism is not high . In order to improve the measurement accuracy, it is necessa...
