Embodiment Construction

[0023] Such as figure 1 Shown is a tooling device for the assembly between the rotor and the stator of a shielded motor. The tooling bracket 1 is fixed to the rotor 6 through the threaded hole at the shaft end. The outer diameter of the boss of the positioning sleeve 2 is matched with the inner diameter of the tooling bracket 1 and connected by bolts. ,Such as figure 2 As shown, the inner diameter of the positioning sleeve 2 matches the outer diameter of the step of the rotor 6, and there are three aluminum brackets 3, which are evenly distributed on the tooling bracket 1 and connected with bolts; the upper nylon guide block 4 and the lower nylon guide block 5 pass through the cylinder respectively. The pin is positioned with the aluminum bracket 3 and fixed by bolts.

[0024] Such as image 3 As shown, the inner diameter of the upper nylon guide block 4 is matched with the small outer diameter of the rotor 6, the outer diameter of the upper nylon guide block 4 is matched w...

Abstract

The invention relates to a tooling device used for assembly of a rotor and a stator in a shielding electric motor, wherein three aluminum supports uniformly distributed on a tooling bracket and a nylon block fixed on the surface of the same are used to realize positioning guidance, a whole set of tool is connected to the rotor by an axial end threaded hole, radial positioning is realized by a stepped shaft small circle, and thus the objective to assemble the rotator into the stator is realized. In tooling device used for the assembly of the rotor and the stator in the shielding electric motor provided by the invention, lightweight design is adopted, so that tool assembly and disassembly are convenient; and the guiding and positioning of a non-metal material are adopted, so that scratches to a product surface during the assembly are avoided. The tooling device has high accuracy of the positioning guiding, can realize requirements of the rotor with a small volume for the assembly and the positioning, is simple in the assembly and disassembly, can greatly reduce time cost, and can shorten a product manufacture period.

Description

technical field [0001] The invention relates to a tooling device used for assembling between a rotor and a stator of a shielded motor. Background technique [0002] In the production process of shielded motors, the assembly between the rotor and the stator is a key process. With the development of motor products, the gap between the rotor shielding sleeve and the stator shielding sleeve is getting smaller and smaller, resulting in difficult assembly and high risk. Due to the The thickness of the stator shielding sleeve is relatively thin, generally (0.5mm ~ 1mm or so), and the rotor and the stator shielding sleeve are relatively long, which is likely to fail due to the deviation of the crane and the assembly position during the assembly process, and is very likely to bump Therefore, at present, the assembly between the rotor and the stator of the shielded motor is mostly carried out by increasing the gap between the stator and the rotor and inserting a thin nylon plate into ...
