To the stability for maintaining rotor to rotate.
For the rotor in CT, machining dimension requires height, including rotates swivel and balance weight, and rotary body includes annular
Disk and supporting walls, have several threaded connection holes on annular disk, supporting walls shape in a ring, and connect the outer rim of annular disk, support
The upper surface of wall is A roller surface, and lower end surface is B roller surface, and outer circumference surface is C circle roller surface, and balance weight connects rotary body, for
The flatness of A roller surface and B roller surface therein is no more than 0.05mm, and C justifies the bounce of roller surface no more than 0.08mm, therefore
It needs to detect it after the completion of rotor machining.When being detected, it is necessary first to first by rotor supports in tooling, then
The measuring tools such as roundness measuring equipment are recycled to carry out the detection of flatness, circularity to each face of rotor.Shown in traditional tooling drawing 1,
Three regions of B roller surface are respectively supported at using three cylinders, it is easy for installation in this way, it is easily operated, but exist
Many problems: firstly, workpiece, in the case where this mode supports, discontinuity equalization may be influenced due to rotor self gravity
Cause A roller surface, B roller surface, C circle roller surface that irregular deformation occurs；Secondly, support cylinder is placed below B roller surface, survey
It can interfere, can not settle at one go in amount machine stylus traveling process, after one-shot measurement, need to rotate rotor, thus
B roller surface is showed out what one-shot measurement was capped, then carries out double measurement, reduces detection efficiency；Finally, workpiece is put
Belong to face and face contact on three cylinders, inevitably there is gap between the two, can generate the phenomenon that being uneven, when measurement will appear
Workpiece can seating unevenly steady phenomenon, the above variety of problems, thus will lead to detection inaccuracy, need repeatedly to be detected, detect
Result it is undesirable.
Summary of the invention
