Embodiment Construction
[0023] like 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. ,like 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] like image 3 As shown, the inner diameter of the upper nylon guide block 4 matches the small outer diameter of the rotor 6, the outer diameter of the upper nylon guide block 4 matches the inner diameter of...

The invention relates to a tooling device for assembling between the rotor and the stator of a shielded motor. Three aluminum brackets evenly distributed on the tooling bracket and nylon blocks fixed on the surface are used as positioning guides, and the screw holes are used to guide the The whole set of tools is connected to the rotor and radially positioned through the small circle of the stepped shaft to achieve the purpose of installing the rotor into the stator. The invention adopts lightweight design, which is convenient for tool disassembly and assembly; non-metallic material is used for guiding and positioning to avoid scratching the surface of the product during the assembly process; the positioning and guiding precision is high, and the rotor assembly and positioning requirements with less air can be realized; the assembly and disassembly process of the device is simple , can greatly reduce the cost of man-hours and shorten the product manufacturing cycle.
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 ...
