Description

Technical Field

[0001] The utility model belongs to the technical field of generator main shaft forging detection, in particular to a generator set main shaft forging detection device. Background Art

[0002] The main shaft forging of the generator set is one of the key components of the generator set. It has the characteristics and requirements of high strength, high toughness, high precision, etc. It is the core component for transmitting torque. After the main shaft forging is manufactured in the workshop, it needs to go through multiple quality inspections in the quality inspection process. Only after all the quality inspections are passed can it be put into storage and put on the market for use.

[0003] At present, for the non-in-service generator set spindle forging inspection equipment, the spindle forging is mostly driven to rotate, and the fixed related inspection mechanism performs 360-degree inspection on the coaxiality of the spindle side. However, the spindle forgings of large generator sets are often large in size and extremely heavy, which puts high demands on the rotation drive mechanism of the spindle forging and consumes a large driving cost. Moreover, in some inspection equipment, the spindle forging is inserted into an integrated annular inspection mechanism for inspection. For large spindle forgings, it is difficult to insert the inspection mechanism slightly larger than its outer diameter, which greatly increases the difficulty and cost of loading and unloading.
