Problems solved by technology

[0004] Since the motor bearing pressure plate needs to be assembled first, and the heated motor bearing is picked up while wearing high-temperature gloves, on the one hand, due to the many and cumbersome procedures, it is often forgotten to assemble the motor bearing pressure plate; Scald phenomenon caused by panic; seriously affect the safety of employees and the cost of dismantling motor bearings caused by assembly errors, scrapped bearings and man-hours

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0024] like figure 1 As shown, the error-proofing method for assembly of the bearing pressure plate of the automobile motor production line includes the following steps:

[0025] Manually start the intermediate relay switch button of the bearing heater, and turn on the bearing heater to start heating the bearing. After the intermediate relay switch is manually pressed, it cannot bounce back and is always on;

[0026] When the bearing heater heats the bearing, the temperature of the bearing heating is identified by the thermocouple temperature sensor. When the bearing temperature reaches the set temperature required by the bearing heater, the thermocouple temperature sensor transmits the signal to the red indicator light to flash. When the bearing temperature When the set temperature required f...

Abstract

The invention discloses a bearing pressing plate assembly error preventing method for an automobile motor production line. A motor bearing pressing plate and a motor bearing mounting process are correlated in a closed-loop mode, and when any process is not executed, relevant processes cannot be executed, so that the phenomenon that a motor bearing is directly disassembled frequently due to the fact that the motor bearing pressing plate is forgotten to be assembled in the production line is eliminated, the production quality and efficiency are improved, and the cost is reduced; and a red indicator lamp is adopted to inform a worker to wear high-temperature protective gloves, so that the risk that worker is scalded is reduced, and the operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobile motors, in particular to an error-proofing method for assembling a bearing pressure plate of an automobile motor production line. Background technique [0002] With the global energy crisis, environmental pollution and other issues becoming increasingly prominent, new energy vehicles have become the focus of the development of domestic and foreign automobile companies. The core components of new energy vehicles are motors, motor controllers and batteries, and the assembly efficiency of motors is directly related to the company's output. [0003] There is a bearing on the left and right ends of the motor shaft driving the motor. One of the bearings is fixed by a bearing pressure plate, and the other bearing uses a wave gasket to adjust the axial movement of the motor. Therefore, when the motor rotor is assembled, the bearing pressure plate must be installed. Then install the bearing shrink slee...
