Technical Problem

[0003]目前齿轮箱箱体的斜孔由上端面向下钻，钻到出口位置；箱体斜孔需要与轴承盖的斜孔连通，如果钻进角度稍微有所转动，到出口位置会与轴承盖斜孔有偏差，导致齿轮箱箱体加工完斜孔后与轴承盖斜孔连通性差，无法保证组装完成后的连通效果

Benefits of technology

[0019] (1) The guiding device of the present invention includes a guiding body, on which an inclined drill sleeve is installed. The guide body is mounted on the housing with the mounting surface of the housing and the bearing cover as the reference surface, and with the surface connected to the bearing cover as the starting point, the drill bit can process the inclined hole of the housing from bottom to top, ensuring the consistency of the end position of the inclined hole of the housing and the upper end position of the inclined hole of the bearing cover, and ensuring the oil circuit connectivity; overcoming the problem of poor connectivity caused by drilling the inclined hole of the housing from the upper end to the lower end, and realizing accurate and reliable positioning of the gearbox housing drilling.
