Problems solved by technology

In the general processing process, the inner hole and the end face are all processed by the lathe, and the rest of the surrounding plane and drilling are processed by the machining center. Because the blank has the phenomenon of box expansion, it is difficult to control the depth of drilling and tapping in this process.
During the milling and drilling process of the shell, the motor needs to be turned over frequently, and the tooling needs to be removed every time. After turning over, the installation and positioning are reproduced. The operation is cumbersome and the processing efficiency is low.

Description

technical field [0001] The invention relates to an explosion-proof motor casing processing device and a processing technology, belonging to the technical field of explosion-proof motor casing processing. Background technique [0002] Explosion-proof motor casing is a kind of precision-processed workpiece in mechanical processing. It is used for special motors and is widely used in special fields where combustible gas explosions may occur, such as petroleum and mining. In the general processing process, the inner hole and the end face are all processed by the lathe, and the rest of the surrounding plane and drilling are processed by the machining center. Because the blank has a box expansion phenomenon, it is difficult to control the depth of drilling and tapping in this process. During the milling and drilling process of the casing, the motor needs to be turned over frequently, and the tooling needs to be removed every time, and the installation and positioning must be repea...
