Description

Technical Field

[0001] The utility model relates to the technical field of processing positioning tables, in particular to a processing positioning table for a motor end cover. Background Art

[0002] The end cover is a rear cover installed behind the motor and other casings, commonly known as the "end cover". As the market's requirements for automotive air-conditioning fans continue to increase, there are higher requirements for the fan's reliability, accuracy, low noise, and long life. The traditional motor's end cover structure is a sheet metal stretching part with poor processing technology. It was later improved to a die-cast aluminum alloy process, and the processing technology and reliability were significantly improved. When processing the end cover, a processing positioning table is required to fix and position the end cover, which can not only improve the end cover processing efficiency, but also ensure the end cover processing quality and increase the company's production efficiency. Therefore, a motor end cover processing positioning table is very important in the motor end cover processing process.

[0003] To ensure the sealing of the output shaft, the motor end cover needs to ensure accurate positioning of the mounting holes during the manufacturing process. The mounting holes of the motor end cover need to be drilled by a drilling machine. When processing the mounting holes, the existing mounting hole processing fixture first positions the motor end cover to be processed on the fixture, and then the staff needs to manually move the clamping fixture to align the mounting ears with the drill bit one by one to complete the processing of all the mounting holes. The existing mounting hole processing fixture requires multiple manual positioning when processing the motor end cover mounting holes, which will reduce the accuracy and efficiency of the motor end cover mounting hole processing.
