Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a testing device for a gearbox cover plate. Background Technology

[0002] The gearbox is fitted with a cover plate, which typically undergoes multiple inspections after production before being installed on the gearbox. However, existing inspection equipment has certain drawbacks. Traditional inspection equipment often uses independent inspection stations for each inspection requirement, requiring the cover plate component to be manually transferred from one station to another for further inspection. Moreover, some inspections still require manual labor, resulting in lower inspection efficiency. While more integrated inspection equipment can optimize the inspection of cover plate components into a single device, it suffers from issues such as long transport distances, excessive floor space, and unreasonable layout due to the need to avoid interference between the inspection equipment installed at each station and the conveying system. Therefore, a new type of inspection equipment is needed to address these problems. Utility Model Content
