Therefore, when processing the cylindrical casing, the parallelism between the two end faces of the cylindrical casing and the perpendicularity to the central axis of the inner cavity are very high. The processing of the two end faces and the inner cavity of the cylindrical casing is completed under the condition of holding, which affects the performance of the motor

Embodiment Construction
[0017] Such as figure 1 , 2 As shown, the jig for machining the motor casing includes a plurality of combination blocks 1, which are combined into a ring shape, and the plurality of combination blocks 1 are preferably divided into equal parts along the circumference. In this specific embodiment, 12 combination blocks 1 are arranged in total. Such as image 3 As shown, the ring-shaped outer peripheral surface formed by the combination block 1 is conical, and the shape of the inner hole of the ring formed by the combination blocks 1 matches the cross-sectional profile of the cylindrical casing 6 (it needs to be explained It is important to note that the "matching" here can be that the overall shape of the surface of the inner hole of the ring formed by a plurality of combination blocks 1 fits with the surface of the cylindrical casing 6, or it can be partially matched with the cylindrical casing 6 from different directions. The surfaces are attached to each other, as long as ...

The invention relates to a motor casing processing clamp, which comprises a plurality of combination blocks, wherein the combination blocks are combined to form a circular ring, an inner hole of the circular ring formed by the combination of the combination blocks is matched with the section profile of a motor casing in shape, the combination blocks can be radially moved, the peripheral surface of the circular ring formed by the combination of the combination blocks is a conical surface in shape, and the peripheral surface is provided with a clamping structure used for pulling the clamp to the end with smaller diameter in the axial direction. By the slope action of the conical surface, the clamp enables the combination blocks to contract to the center of the circular ring so as to clamp the cylindrical shell. Because the clamp is annular, both ends of the cylindrical shell fixed on the clamp and the inner hole can be processed, and the mutual parallelism between two end surfaces and the perpendicularity of the two end surfaces and the central axis of an inner chamber can be well guaranteed without clamping many times, so that the product quality is improved.
Description
technical field [0001] The invention relates to a jig for processing a motor casing. Background technique [0002] The casing of the motor usually includes a cylindrical casing, a front end cover and a rear end cover. The stator of the motor is fixedly installed in the cylindrical casing, the rotor is placed in the stator, and the front end cover and the rear end cover are respectively fixed on the front of the cylindrical casing. 1. At the rear two ends, the rotor and stator are enclosed in the casing, and the two ends of the rotor shaft are installed on the front end cover and the rear end cover through bearings. The rotor and the stator are required to be highly concentric. If the rotor and the stator are not concentric, the performance of the motor will be affected. Therefore, when processing the cylindrical casing, the parallelism between the two end faces of the cylindrical casing and the perpendicularity to the central axis of the inner cavity are very high. The pro...
