Embodiment 1

[0038] A motor production process is provided, including:

[0039] 1. Skeleton winding

[0040] 1. Operators should confirm the conformity of equipment, tooling, testing equipment, process documents and products to be processed before operation, and record the "Equipment Inspection and Operation Condition Confirmation Record Form". .

[0041] 2. Before the operation, the operator conducts a counting comparison and evaluation on the digital screen of the winding machine, and the operation can only be started after passing the test. The evaluation result is recorded in the "Counting Disk Cycle Evaluation Record Form".

[0042] 3. Adjust the data on the digital screen of the device to zero.

[0043]4. Put the skeleton in the middle of the skeleton winding die, install it on the main shaft of the equipment, and fix it with a fastening nut before winding. The number of winding turns is 390±10. When the remaining 10 turns are reached, release the pressure tape and then wind. Wire...

Abstract

The invention relates to a motor production process. The motor production process comprises the steps of (1) performing winding on a framework; (2) performing press-fitting on a shaft and a front clawpole; (3) performing press-fitting on a framework assembly; (4) performing press-fitting on a rear claw pole; (5) performing rotor dynamic balancing; (6) pressing an inner ferrule; (7) assembling a front fan; (8) assembling a rear fan; (9) performing press-fitting on a collector ring; (10) performing tin soldering and pressure resistance inspection; (11) performing insulation treatment on a rotorassembly; (12) turning an outer circle of the rotor assembly; (13) turning a ferrule plane; (14) turning the collector ring; (15) applying anti-rust oil; and (16) inspecting the rotor assembly. According to the motor production process, a produced motor is high in precision; high-quality requirements are met; the service life of the motor is prolonged; the safety is higher; and the sustainable development is better.

Description

technical field [0001] The invention belongs to the technical field of automobile motor processing, and relates to a motor production process. Background technique [0002] The motor usually includes a motor barrel (motor housing), two end covers arranged at both ends of the motor barrel, a stator arranged inside the motor barrel, and a rotor and other structures. When assembling the motor rotor structure, it is necessary to wind the skeleton first, and then match it with the shaft, pole claws, inner ferrule, fan, collector ring, etc. The existing rotor preparation process has a very high workmanship accuracy , but it is far from enough for some fields with higher precision requirements such as automobiles, and as far as the current production level is concerned, there are not many processes that can meet this kind of production. Even if the overall steps are consistent, each step The difference in process parameters also leads to different performance of the motor after co...
