Problems solved by technology

At present, a three-coordinate measuring machine is used to measure the coaxiality error of the stator positioning boss 42 relative to the bearing hole 41, but the detection time is long, so it is far from meeting the production requirements

Abstract

The invention discloses a testing fixture used for a generator set wedge box cover. The generator set wedge box cover is provided with a bearing hole and a stator positioning boss. The testing fixture comprises a pedestal, a positioning shaft which coaxially passes through the bearing hole of the generator set wedge box cover and a fixing component. The pedestal comprises an installation portion. The fixing component is used for fixing the generator set wedge box cover on a top end of the installation portion. The positioning shaft is vertically installed on the pedestal through a rotatable mode. The positioning shaft is provided with a dial indicator. A measuring head of the dial indicator is contacted with an outer circumference wall of the stator positioning boss. In the invention, an assembling standard of components are designed to be a measuring standard so that a standard misalignment error is eliminated and detection precision is increased; the structure is simple, a price is low, operation is convenient, detection is fast and a three-coordinate measuring machine is completely replaced; and the testing fixture can be used for a production line and dynamic monitoring is realized.

Description

technical field [0001] The invention relates to a checking tool for a wedge-shaped box cover of a generating set. Background technique [0002] Such as figure 1 , 2 As shown, some generator sets are equipped with an organic body 70 , a wedge-shaped case cover 40 , a rotor 50 and a stator 60 . The body 70 and the wedge-shaped case cover 40 are matched by inclined surfaces, and are integrated into one body through positioning pins. The rotor 50 is installed in the body 70 and the bearing hole 41 of the wedge-shaped case cover 40 through bearings; The stator positioning boss 42 performs positioning. Because the coaxiality of the bearing hole 41 of the wedge-shaped case cover 40 and the stator positioning boss 42 directly affects the coaxiality of the rotor 50 relative to the stator 60, therefore, after the wedge-shaped case cover 40 is processed, it is necessary to measure the stator positioning boss 42 and The coaxiality of the bearing hole 41. At present, a three-coordin...
