Abstract
The utility model belongs to the field of machining and detection devices, and specifically relates to a tool for detecting the eccentric symmetry degree of a bent axle of a freezer compressor. A technical problem to be solved is to provide the tool for detecting the eccentric symmetry degree of the bent axle of the freezer compressor, wherein the tool is simple in operation, is accurate in measurement, and is low in cost. The tool comprises a positioning device and a detection device. The positioning device comprises a workbench and a supporting plate. The supporting plate is perpendicular to a side of the upper part of the workbench. The upper part of the supporting plate is laterally provided with a through hole. The detection device comprises a stepped mandril and a lever indicator. The stepped mandril passes through the through hole at the upper part of the supporting plate and then is fixed with the supporting plate. The interior of the stepped mandril is provided with a blind hole. The lever indicator is installed in the blind hole of the stepped mandril. The external surface of the front part of the stepped mandril is provided with a lateral groove which is communicated with the blind hole. The measuring head of the lever indicator passes through the lateral groove, and then contacts with the internal surface of a bent axle hole of the base.
