Problems solved by technology
At present, there are few mature products for space multi-degree-of-freedom measurement, and they mainly rely on imports. The disadvantages are that the price is high and unacceptable; the second is that the precision is low and cannot meet the requirements of precision assembly.
And for the working conditions where the assembly space is narrow and the instrument is difficult to "stand in", existing products cannot directly measure the spatial position of the installation point, and the accuracy of other measurable parts cannot meet the measurement requirements

The invention discloses a six-degree-of-freedom indirect measuring instrument, which relates to the technical field of automatic assembly and includes: a checking tool, a testing device and a computing device; the checking tool includes a checking tool bracket and a checking tool block, and one end of the checking tool bracket is used for fixing On the other hand, the checker block is fixedly arranged on the other end of the checker bracket; the detection device is used to be fixedly arranged on the workpiece, the detection device is used to measure the spatial position of the checker block, the calculation device is electrically connected to the detection device, and the calculation device is used for Calculate the spatial position and pose of the workpiece relative to the installation point, thereby overcoming the defects that the existing existing products cannot directly measure the spatial position of the installation point, and the accuracy of other measurable parts cannot meet the measurement requirements. The present invention can Accurately measure the space six degrees of freedom of the installation point, and is conducive to the automatic assembly of the workpiece.
Description
technical field [0001] The invention relates to the technical field of automatic assembly, in particular to a six-degree-of-freedom indirect measuring instrument. Background technique [0002] With the rapid development of industrial technology, the adoption of automated assembly technology has become an inevitable trend. Compared with manual assembly, automated assembly has the advantages of high assembly quality, high efficiency, and low labor intensity. The key technology of automatic assembly is the spatial positioning of the workpiece relative to the installation point. At present, there are few mature products for spatial multi-degree-of-freedom measurement, and they mainly rely on imports. The disadvantages are that the price is high and unacceptable; the second is that the precision is low and cannot meet the requirements of precision assembly. And for the working conditions where the assembly space is narrow and the instrument is difficult to "stand in", existing p...
