Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a core misalignment mechanism. Background Technology

[0002] The assembly of iron-core rotor shafts requires the use of an automatic iron-core rotor shaft assembly machine. This machine inserts the rotor shaft into a core body composed of multiple stacked sheet iron cores, and then presses the core body with the rotor shaft inserted into it using a press-fitting structure. However, rotors assembled by conventional automatic iron-core rotor shaft assembly machines often have significant differences in the balance of the stacked sheet iron cores. This necessitates trimming the sides of the core body with larger balance differences to ensure product quality and meet production requirements, increasing manufacturing time and affecting the rotor's appearance.

The feeding position is on the first feed channel 110, and the adjustment position is at the opening 121 of the second feed channel 120. In this embodiment, the feed channel 101 composed of the first feed channel 110 and the second feed channel 120 enables the material rack 200, the first feeding mechanism 300, the rotating mechanism 400, the second feeding mechanism 500, and the assembly mechanism 600 to be compactly distributed, and facilitates the transfer of the iron core body 810.

A first fixing block 240 is connected to the upper end of each guide rod 230, and a second fixing block 130 is provided on the material platform 100. The first fixing block 240 overlaps the second fixing block 130 so that the lower end of the guide rod 230 is inserted into the material dropper 210. Preferably, two guide rods 230 are provided.

[0070] Specifically, continue to refer to Figure 5 As shown, the first fixing block 240 is stepped, and the second fixing block 130 is provided with a limiting groove 131.

The positioning mechanism 700 is configured to guide the movement of the sheet iron core 811 from the material rack 200 to the loading position so that the sheet iron core 811 is stacked neatly and to prevent misalignment between the sheet iron core 811, which would affect subsequent processes.

[0075] Specifically, the positioning mechanism 700 includes two guide members 710 and a guide drive device 720 that is driven and connected to the guide members 710 in a one-to-one manner. The guide drive device 720 is fixed on the material platform 100. Guide grooves 111 are connected to both sides of the material channel 101. The guide grooves 111 are located at the loading position. The guide members 710 are slidably arranged in the guide grooves 111 in a one-to-one manner. The drive device can drive the guide members 710 to slide in the guide grooves 111 so that at least part of the guide members 710 can protrude out of the guide grooves 111 and be placed in the material channel 101.
