Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a motor housing clamp. Background Art

[0002] The existing special clamps for motor shells usually use expansion sleeves for positioning clamps, but due to the defects of the existing expansion structure itself, the expansion sleeve is not elastic enough to clamp the motor shell, and the expansion sleeve is easy to break and scrap, which is cumbersome to repair and has high repair costs. When drilling holes in the motor, an angular auxiliary support device is also used, but the existing angular auxiliary support device usually uses a compression spring for elastic support. Due to the large axial force of drilling, the spring cannot withstand the axial force of drilling, which easily causes the motor shell to rotate and make the motor shell scrapped. Therefore, it is now planned to develop a special clamp for the motor shell.
