Description

Technical Field

[0001] The utility model relates to the technical field of automobile motor processing auxiliary equipment, in particular to a clamping tool for a new energy automobile motor end cover. Background Art

[0002] An automotive motor end cap is a component of the motor in new energy vehicles. It typically consists of a main body with a central through-hole (the motor shaft passage) at its center, along with circumferentially distributed reinforcing ribs. The outer wall of the main body is also typically equipped with raised portions. Its primary function is to determine the spatial position of the rotor shaft. It requires the use of various bearing types and is connected to the housing that secures the motor's stator through the main body to ensure proper clearance between the rotor and stator. After production, the motor end cap requires further processing.

[0003] For example, a clamping fixture for a motor end cover of a new energy vehicle is disclosed with the publication number CN218504366U, wherein the clamping fixture for a motor end cover of a new energy vehicle includes a clamping panel, one end of the clamping panel is rotatably engaged with a threaded rod, the middle part of the threaded rod is threadedly connected to a threaded block, one side of the threaded block is fixedly connected to a fixed block, a sliding groove is provided in the middle of the other end of the clamping panel, the middle part of the sliding groove is slidably engaged with a slider, one end of the slider and the fixed block is fixedly connected with a sliding rod; the other ends of the slider and the fixed block are both rotatably engaged with a forward threaded rod and a reverse threaded rod, and the forward threaded rod and the reverse threaded rod are fixedly connected. Through the above structure, a positive and negative design is realized by the forward threaded rod and the reverse threaded rod, so that the clamping side plate can be moved closer to the middle or away from the two ends, thereby realizing the clamping of motor end covers of different sizes.
