Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Working principle of the present invention:

[0025] First, the stator is placed on the platform, and the operator holds the claw on the pull ring to drive the pin to separate from the inner wall of the round hole, and then takes the end of a coil on the stator to pass through the groove on the support rod and the round hole on the turntable in turn. , the operator loosens the pull ring, and the latch slides toward the axis of the turntable under the elastic force of the pressure spring, that is, the claws are snapped onto the inner peripheral wall of the round hole, thereby completing the clamping of the free end of the coil; then, the second cylinder works to clamp the coil in the groove on the support rod;

[0026] Then, the motor works to drive the second rotating shaft to rotate, and the second rotating shaft drives the external ge...

Abstract

The invention discloses a device for welding the end of a coil on a stator. The device for welding the end of the coil on the stator comprises a workbench (1). A platform (2) is slidably connected to the workbench in the horizontal direction, and a first air cylinder (36) used for driving the platform (2) to reciprocate is arranged on the workbench (1). A guide device is arranged between the workbench (1) and the platform (2). A first vertical plate (3) used for containing the stator (5) is arranged at one end of the platform (2). A second vertical plate (4) is arranged at the other end of the platform (2). According to the device for welding the end of the coil on the stator, welding omission of a wire harness can be avoided, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of stator coil end welding, in particular to a device for welding end coils on a stator. Background technique [0002] The stator of a three-phase AC motor is composed of a stator core and a three-phase winding coil embedded in a slot wedge of the stator core. After the coils are embedded on the slot wedges, some of the coils exposed at the ends of the stator are dispersed. And before the stator is put into use, the wire harness of the exposed part on each coil must be welded into one to form a welding head, which must include every wire on the corresponding coil; because, if the welding on a coil If one wire is leaked at the head, but there is no missing soldering on the other coils, it will cause a three-phase electrical imbalance, that is, the three-phase AC motor cannot work normally, resulting in a failure of the motor. In the prior art, the welding of the coil end is done manually. The operator holds...
