Embodiment Construction

[0011] The present invention will be further described below in conjunction with drawings and embodiments.

[0012] as attached figure 1 As shown, a DC motor commutator slotting machine includes a rotor bracket 1, a pneumatic motor 3 arranged on the cutting frame 2, a cutting tool 4 connected with the pneumatic motor 3, and a mechanism for controlling the cutting frame 2 to move up and down. Adjust the controller 5 up and down, and control the front and rear adjustment controller 6 that the cutting frame 2 moves forward and backward.

[0013] The up and down adjustment controller 5 includes a positioning lever handle 5-1 and a positioning gear set 5-2.

[0014] The front and rear adjustment controller 6 includes a motor 6-1, a transmission mechanism 6-2 and a walking guide rail 6-2.

[0015] After the DC motor commutator that needs to be overhauled is processed by a lathe, it is placed on the rotor support 1 and the mica sheet groove that needs to be cut is placed on the upp...

Abstract

The invention discloses a groove broacher for a commutator of a direct current motor and relates to a groove broacher for a mica sheet groove in a commutator of a direct current motor. The groove broacher comprises a rotor spider, a motor, a cutting tool, a vertical adjustment controller and a horizontal adjustment controller, wherein the motor is arranged on a cutting frame; the cutting tool is connected with the motor; the vertical adjustment controller is used for controlling the vertical movement of the cutting frame; and the horizontal adjustment controller is used for controlling the horizontal movement of the cutting frame. The groove broacher is used as a tool special for repairing the direct current motor, so that the maintenance quality and the time limitation of the direct current motor are guaranteed; and the original manual work is changed into mechanical operation, so that the physical labor is greatly reduced, and the market blank is filled.

Description

technical field [0001] The invention relates to a repairing device for a commutator of a DC motor, in particular to a slotting machine for insulating mica sheet grooves in the commutator. Background technique [0002] In the DC motor, the commutator cooperates with the brush to convert the external DC power into the alternating current in the armature coil, so that the direction of the electromagnetic torque remains constant. The commutator is a cylinder composed of many commutation segments, and the commutation segments are insulated with mica sheets to commutate. During the use of the DC motor, the commutator and the brushes are constantly and repeatedly rubbed, and the commutator will be worn and must be reprocessed. The processed commutator slices are recessed downwards, while the mica slices protrude outwards, and the commutator cannot work. The protruding mica sheet must be removed to form a groove, so that the commutator can work normally and the current commutation...
