Description

Technical Field

[0001] The present invention belongs to the field of machining, and particularly relates to a motor and gearbox assembly device and its operation method. Background Art

[0002] A motor is an electric motor or an engine. Its working principle is that an energized coil rotates under the action of a magnetic field to drive the starter rotor to rotate, and the small gear on the rotor drives the engine flywheel to rotate; a gearbox is a transmission. By engaging gears of different sizes, the rotation speed and torque are increased or decreased, also known as a gearbox. When a large gear drives a small gear, the speed is increased and the torque is reduced, and when a small gear drives a large gear, the speed is reduced and the torque is increased; after the motor and the gearbox are assembled, a motor power assembly is formed. When assembling the motor and the gearbox, an assembly device is required.

[0003] Reference can be made to the Chinese patent with the publication number CN207801688U, which provides a motor assembly device. The motor includes a stator assembly and at least a part of a rotor assembly disposed within the stator assembly. The stator assembly includes a housing, a stator core disposed along the inner circumferential surface of the housing, and an annular insulating member disposed on a side of the stator core opposite to the bottom of the housing. The rotor assembly includes a rotating shaft, a bearing, a rotor core, and a sensor magnetic sheet that are sequentially located along the axis direction of the rotor assembly. A bearing receiving portion capable of accommodating the bearing is provided at the bottom of the housing. The motor assembly device includes: a stator assembly device; an insulating member height measuring device for measuring the height of the insulating member relative to the bearing receiving portion in the axial direction of the stator assembly; a rotor assembly device; and a rotor assembly inserting device capable of inserting the rotor assembly into the stator assembly.

[0004] The above patent has the advantages of being able to ensure that the sensor magnetic sheet can be installed at an appropriate height and ensuring the precise positioning between the sensor magnetic sheet and the circuit board, but it also has defects. For example, its degree of automation is relatively low, manual assistance is required, which wastes labor, and the participation of manual labor results in low efficiency and poor accuracy.
