Description

Technical Field

[0001] This utility model belongs to the field of drilling devices, and in particular relates to a bearing cover fixing drill jig and an automatic drilling device for bearing covers. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Currently, during the maintenance of high-speed trains, if modifications to the hydraulic system are required, through holes need to be machined on the protruding part of the gearbox bearing cover to form an hydraulic passage with the gearbox housing. The existing method for machining through holes in the bearing cover typically involves manual drilling. Due to differences in the strength of the workers, this results in variations in the diameter of the drilled holes, potentially leading to the scrapping of components.

[0004] To address the shortcomings of manual drilling, existing automatic drilling devices are designed for drilling large components or components with flat surfaces. Due to the narrow protrusion of the bearing cover and the small drilling space, the existing drilling devices have a high rate of bearing cover scrapping when drilling bearing covers, depending on the operator's skill level.
