Description

Technical Field

[0001] The utility model relates to the technical field of brushed motor stator lining processing, in particular to an EPS brushed motor stator lining automatic welding device. Background Art

[0002] "EPS" is usually the abbreviation of "Electric Power Steering", which means "electric power steering". It is an automobile steering system that uses an electric motor to assist the driver in steering, improving driving comfort and handling. "Brushed motor" is a common type of motor, which uses brushes and commutators to achieve current commutation, allowing the motor to rotate continuously. "Stator lining" is the fixed part of the motor, and the lining is a thin sheet installed inside the stator for insulation and protection of the stator winding.

[0003] According to the "Automatic Welding Device for Stator Lining of EPS Brushed Motor" proposed in CN112296552A, the automatic welding device for stator lining of EPS brushed motor includes a base, a rolled copper rod, a spot welding device, a feeding device, a feeding device, a jacking device, a rolling device and a material withdrawing device. The lining is sucked by the suction cup on the feeding device and pulled to fall onto the sliding bracket on the feeding device. The sliding bracket is driven by the sliding bracket cylinder to send the lining between the rolled copper rod and the jacking device. The jacking bracket on the jacking device rises and holds the lining against the lower end of the rolled copper rod. The rolling pressure block on the rolling device presses the two ends of the lining against the upper end of the rolled copper rod. The spot welding device spot welds the connection between the two ends of the lining. The push plate on the material withdrawing device pushes the welded lining away from the rolled copper rod under the drive of the material withdrawing cylinder.

[0004] Although the above device realizes full automation of lining feeding, curling welding and unloading processes, the lining feeding continuity is poor, the processing steps are complicated, and it is not convenient for continuous and rapid feeding, forming and welding, and the processing efficiency needs to be further improved.

[0005] Therefore, we propose an automatic welding device for stator lining of EPS brushed motor to solve the problems in the above background. Utility Model Content

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] First, the utility model conveys the stainless steel lining to the forming mechanism through the material conveying gap of the conveying mechanism, adjusts the position of the ball seat through the electric push rod, so that the conveyed stainless steel lining enters under the roller ball, and the roller ball inside the ball seat cooperates with the roller groove to bend the middle part of the stainless steel lining, lift up the two ends, and then enter the plastic channel, move inside the plastic channel, and bend further due to the restriction of the plastic channel. When it enters the rear end of the plastic channel, it becomes annular, and the two ends are close to each other, and then it is welded by the upper welding mechanism.

[0017] Second, the utility model fits the upper and lower surfaces of the stainless steel lining by two conveyor belts inside the stabilizing frame on each side, and conveys the stainless steel lining through the material conveying gap between the two conveyor belts, which not only improves the feeding speed, but also prevents it from deflecting, so that it enters under the roller ball stably and orderly, is first bent in the middle, and then formed through the plastic channel, ensuring efficient and stable processing.
