Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that during the assembly process, when the commutator is not positioned accurately, the mounting lugs cannot be opposed to the winding grooves one by one after the commutator is fixed, and the commutator is installed during the pushing process. When the hole is not aligned with the rotor shaft, the frictional force will be greater, which will easily cause the rotor core to slide axially on the rotor shaft and cause damage

Embodiment Construction

[0036] The following is attached Figure 1-6 The application is described in further detail.

[0037] Such as figure 1 As shown, the micro-motor rotor 4 mainly includes a rotor core 41 and a rotor shaft 43 running through the center of the rotor core 41. The side wall of the rotor core 41 is provided with several winding slots 42, and at one end of the rotor core 41 The commutator 5 is plugged into the rotor shaft 43, and the copper wire wound in the winding groove 42 needs to be connected with the commutator 5. In order to improve the connection effect of the copper wire, as figure 2 As shown, at present, on the commutator 5, the circumferential array is opposite to the hanging lugs 51 of the winding slots 42 one by one. The side wall is extruded and deformed, thereby clamping the copper wire for fixing.

[0038] The embodiment of the application discloses a micro-motor rotor commutator assembly device. refer to figure 1 , 3 , comprising a frame 6 and a feeding mechani...

Abstract

The application relates to a micro-motor rotor commutator assembly device, which includes a frame and a feeding mechanism, a feeding mechanism, and a pressing mechanism arranged on the frame. The pressing mechanism includes a bottom plate, a pressing expander, and a pushing rod. One end of the ejector rod is fixed to the telescopic rod of the top-pressure expansion device. The end of the ejector rod facing the bottom plate is provided with a relief hole for the rotor shaft to extend into. The shaft groove, the iron core groove near the end of the ejector rod is provided with a pressure groove, the center of the bottom of the core groove is provided with a positioning rib along the length direction, and the pressure groove is provided with at least one along the length direction and for the hanging lug to extend into. Guide grooves, one of which is arranged at the center of the bottom of the pressing groove. The application has the effect of accurately positioning the motor rotor and the commutator during the assembly process, and inserting and fitting the commutator and the rotor shaft, and ensuring that the hanging lugs and the winding slots of the commutator are one-to-one relative to each other after the commutator is fixed.

Description

technical field [0001] The present application relates to the field of micro-motor processing equipment, in particular to a micro-motor rotor commutator assembly device. Background technique [0002] The micro-motor rotor mainly includes a rotor core and a rotor shaft running through the center of the rotor core. The side wall of the rotor core is provided with several winding slots, and the rotor shaft at one end of the rotor core is inserted and press-fitted for commutation. The copper wires wound in the winding slots need to be connected to the commutator. In order to improve the connection effect of the copper wires, the circular array on the commutator is currently on the lugs opposite to the winding slots. The copper wires need to be connected to the commutator. When fixing, the copper wire is in contact with the hanging lug, and then the hanging lug is squeezed and deformed toward the side wall of the commutator, thereby clamping the copper wire to realize fixing. ...
