Generator stator and rotor automatic test bench

Abstract

The invention discloses an automatic power generator stator and rotor testing table which comprises a rack, a drive motor, a main spindle box, a tailstock and a stator fixing device. The main spindle box and the tailstock are provided with a main transmission shaft and a tail spindle respectively, wherein the main transmission shaft and the tail spindle are connected to the two ends of a rotor. A transverse main sliding table is arranged between the main spindle box and the tailstock and provided with a transverse auxiliary sliding table, a longitudinal sliding table and a carbon brush machine base. The transverse auxiliary sliding table is provided with a stator locating block and a rotor centering assembly. The longitudinal sliding table is provided with a stator fixing base used for placing a stator and rotor assembly. The carbon brush machine base is provided with a carbon brush assembly and a carbon brush telescopic air cylinder used for driving the carbon brush assembly to move longitudinally. According to the testing table, by means of the pneumatic technology and the accurate locating technology, an automatic clamping device can be controlled automatically in a multi-directional mode, before testing, a power generator is controlled to be automatically located, centered and locked, a carbon brush is fed automatically, operation is convenient, the clamping time is short, the work intensity is low, full-load testing can be achieved, and the index of the testing performance is accurate.

Description

technical field [0001] The invention belongs to the technical field of vibration testing of structural components and impact testing of structural components, and in particular relates to an automatic test bench for stator and rotor of a generator. Background technique [0002] The online performance test method of the stator and rotor of the general generator usually adopts the test method of simulating the actual working load of the motor, which needs to apply a simulated load to the tested generator, but the actual simulated working conditions of the motor under different load sets cannot be obtained. The performance index of the generator under different load conditions.

Problems solved by technology

[0002] The online performance test method of the stator and rotor of the general generator usually adopts the test method of simulating the actual working load of the motor, which needs to apply a simulated load to the tested generator, but the actual simulated working conditions of the motor under different load sets cannot be obtained. The performance index of the generator under different load conditions. At present, the practice of most laboratories is to carry out the load test on the manual test bench or the semi-automatic test bench. Because the load test is easy to cause the generator rotor and the connection shaft taper to heat up and engage. If it is too tight, it will be difficult for the generator rotor to exit. On manual test benches or semi-automatic test benches, it is necessary to manually place the stator and rotor on the tooling for centering and positioning operations, and a set of generator stators and rotors can be at least a dozen kg, making it inconvenient for the operator to operate, and the work intensity is high

[0003] The existing defects of the manual test bench and the semi-automatic test bench: (1) It is not easy to unload the rotor after the loading test, and the cone hole of the rotor is easily damaged after being knocked; (2) The clamping time is 10-15 seconds; (3) The working High strength; (4) When the motor is at full load, the test performance indicators are out of control
