Description

Technical Field

[0001] The utility model relates to the technical field of motor end covers, in particular to a motor end cover processing chuck. Background Art

[0002] The end cover is a cover installed on the motor housing. Motor end cover: The motor housing cover is used to fix and support the motor shaft. The motor end cover generally refers to a cover whose axial dimension is larger than the radial dimension at both ends of the motor. Its main function is to determine the spatial position of the rotor shaft; it cooperates with different forms of bearings and is connected to the stator housing of the motor through the end cover to ensure the clearance between the rotor and the stator; the motor end cover is generally manufactured by a casting process. After the casting is completed, a shell-like structure with an open cavity is formed, and a closed-loop side wall (with an inner wall and an outer wall) is formed. However, after the motor end cover is cast, it usually needs to be fine-machined to ensure the clearance between the rotor and the stator.

[0003] In the related art, since the matching accuracy of the motor end cover after casting is poor, fine machining is usually required to ensure the matching clearance between the rotor and the stator. During the fine machining of the motor end cover, the motor end cover needs to be clamped by a processing chuck; however, the type of the motor end cover varies according to the type of the motor casing, which may be a circular shape structure, a rectangular shape structure, or a shape structure with two parallel straight surfaces and a curved surface. This requires different processing chucks to be used according to different types, which has high manufacturing costs, poor adaptability, and poor practicality. For this reason, we propose a motor end cover processing chuck.

[0004] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content
