Description

TECHNICAL FIELD

[0001] The present application relates to the field of motor manufacturing, in particular to a motor winding lead straightening device. BACKGROUND

[0002] When the motor winding lead is straightened, it is often operated by independent pneumatic bending tool (referring to the lead bending tool of the ring-shaped coil), double-roller straightening machine (referring to the lead straightening device of the thermistor), hydraulic pressure groove table (referring to the motor stator winding shaping device).

[0020] In order to make the above-mentioned purposes, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0021] As Figures 1-6As shown, the motor winding lead wire straightening device provided by the embodiment includes a transmission system, a rotary lifting system, a turnover system, a straightening and pressing groove system, and a controller. The turnover system and the straightening and pressing groove system are sequentially arranged on one side of the transmission system. The rotary lifting system is used for clamping and fixing the motor winding 57 and driving the motor winding 57 to rotate and lift. The transmission system is used for transmitting the rotary lifting system and the motor winding 57 to positions corresponding to the turnover system or the straightening and pressing groove system. The turnover system is used for turning the horizontal lead wire 60 on the upper part of the motor winding 57 into a vertical state. The straightening and pressing groove system is used for straightening the vertical lead wire 60 first and then pressing the straightened lead wire 60 into the vertical clamping groove 59 on the upper part of the outer side wall of the motor winding 57. The transmission system, the rotary lifting system, the turnover system, and the straightening and pressing groove system are all connected with the controller.

[0022] In operation, the rotary lifting system clamps and fixes the motor winding 57. The controller controls the transmission system to transmit the rotary lifting system and the motor winding 57 to a position corresponding to the turnover system. The turnover system turns the horizontal lead wire 60 on the upper part of the motor winding 57 into a vertical state. Then, the controller controls the transmission system to transmit the rotary lifting system and the motor winding 57 to a position corresponding to the straightening and pressing groove system. The straightening and pressing groove system straightens the vertical lead wire 60 first and then presses the straightened lead wire 60 into the vertical clamping groove 59 on the upper part of the outer side wall of the motor winding 57, thereby completing the straightening work of the lead wire 60.

[0023] In the embodiment, the linkage of the systems realizes “one-time clamping and multiple processes completed”, avoids the process of multiple clamping and manual transfer of the existing scattered equipment, reduces the collision and friction of the lead wire 60 in the transfer, thereby reducing the damage rate of the lead wire 60, saving the waiting time between processes, greatly improving the processing efficiency, and improving the consistency.
