Coaxiality detection device of generator main shaft and working method thereof

Abstract

The invention discloses a coaxiality detection device of a generator main shaft and a working method. The coaxiality detection device comprises a detection platform, a main shaft positioning and clamping assembly I, a main shaft positioning and clamping assembly II, a main shaft rotation driving assembly, a CCD detection camera, a camera horizontal driving assembly, a camera vertical driving assembly and a detection rack. According to the coaxiality detection device of the generator main shaft, the main shaft can be fixed through the main shaft positioning and clamping assembly I and the main shaft positioning and clamping assembly II, and the coaxiality of the main shaft can be detected through the CCD camera in the process that the main shaft rotation driving assembly drives the main shaft to rotate, and different positions in the axis direction of the main shaft can be detected through the arranged camera horizontal driving assembly. According to the detection method, in the detection process and the process of adjusting the device to move, the position change of a measuring point is recorded in time, the accuracy of detection data is ensured, the error of a calculated coaxiality result is relatively small and is closer to a true value, and the precision of the whole detection method is improved.

Description

technical field

[0001] The invention belongs to the technical field of generator detection, and in particular relates to a coaxiality detection device for a main shaft of a generator. The invention also relates to a working method of the coaxiality detection device of the main shaft of the generator. Background technique

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It is composed of a power system, a control system, a noise reduction system, a shock absorption system, and an exhaust system. The power system generally includes an internal combustion engine and a generator. The power output shaft of the internal combustion engine and the The power input shaft of the generator is coaxially connected.

[0003] In the assembly of diesel generator sets, the elastic coupling is installed between the diesel engine and the generator. Due to the high-speed operation of the diesel engine in the working s...
