Technical Field

[0001] The utility model relates to a steel wire retaining ring assembling device, belonging to the technical field of motor rotor assembling production equipment. Background Technique

[0002] In the motor rotor assembly production line, pressing steel wires and retaining rings into the rotor shaft is an important link. Refer to Figure 1 as the sectional structure schematic diagram of the rotor. The steel wires and the retaining rings are both assembled on the rotor shaft. The production rhythm of this assembly link often determines the efficiency of the entire production line. At present, during the process of assembling the steel wires and the retaining rings on the motor rotor, due to the inaccurate positioning of the traditional assembly process device and the unstable assembly process, the steel wires and the retaining rings of the motor rotor are prone to eccentricity during interference fitting, resulting in dents and scratches on the surface of the rotor shaft, causing the motor to make noise during operation and affecting the product quality.

[0037] Wire pressing and fitting working process: The conveyor belt 1 transports the rotor 40 to the wire assembly position, and the baffle stops the tray 41; the first rotor clamping and feeding device 21 clamps and flips the rotor 40 on the conveyor belt 1 by 90 degrees and places it on the stamping base at the stamping position of the first stamping device 22, with the rotor shaft 42 facing upwards; the first rotating and guiding device 24 clamps the first guiding shaft 25 and moves it below the clamping jaw 234 of the wire supply device 23. The clamping jaw 234 descends to fit the wire 43 onto the first guiding shaft 25. Then, the first rotating and guiding device 24 rotates the first guiding shaft 25 by 90 degrees, fits the first guiding shaft 25 onto the rotor shaft 42, and finally, the first stamping device 22 presses the wire 43 along the first guiding shaft 25 into the rotor shaft 42 to complete the assembly of the wire 43 on the rotor shaft 42.

[0038] The snap ring assembly system 3 includes a second rotor clamping and feeding device 31, a second stamping device 32, a snap ring supply device 33, a second rotating and guiding device 34, and a second guiding shaft 35, which have the same structures and working principles as those of each part of the wire assembly system 2.

The bottom of the shaft body 251 is provided with a connecting part that matches the rotor shaft 42, and the top of the shaft body 251 is a pointed structure for guiding the stamping of the first stamping device 22 and the second stamping device 32. After the guiding shaft gripper 241 fits the first guiding shaft 25 or the second guiding shaft 35 with the wire 43 or the snap ring 44 onto the rotor shaft 42, the guiding shaft gripper 241 is released, and the punch 223 presses down to embed the first guiding shaft 25 or the second guiding shaft 35 into the inner hole of the punch 223. At the same time, the punch 223 smoothly fits the wire 43 or the snap ring 44 along the first guiding shaft 25 or the second guiding shaft 35 onto the rotor shaft 42.

[0040] The assembly process of the wire 43 or the snap ring 44 relies entirely on the guiding function of the first guiding shaft 25 or the second guiding shaft 35 to complete precise and rapid assembly, avoiding phenomena such as inaccurate positioning and unstable assembly process, preventing eccentricity during the interference fit of the wire 43 and the snap ring 44 of the motor rotor 40, which may cause scratches and nicks on the surface of the rotor shaft 42. This not only improves the assembly quality of the rotor shaft 42 but also improves the assembly efficiency.
