Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode rotor manufacturing technology, specifically a skewed rotor forming device for motors. Background Technology
[0002] In the current booming development of the motor industry, the motor rotor, as a key component, plays a decisive role in the overall performance of the motor due to its quality and production efficiency. Skewed rotors, with their superior advantages in reducing motor noise, minimizing harmonic torque, and improving motor running smoothness, are becoming increasingly popular in various high-performance motor applications.
[0003] Traditional skewed slot rotor manufacturing processes suffer from numerous bottlenecks. Early on, skewed slot rotors were primarily manufactured manually, requiring workers to stack rotor chips one by one. This was not only extremely labor-intensive, but also made it difficult to ensure a tight fit between chips and precise consistency in the skew angles through visual inspection and manual operation. This resulted in inconsistent rotor quality and a high scrap rate. Furthermore, manual operation was extremely inefficient, and this production model was completely unable to meet the demands of large-scale production, severely limiting the company's capacity expansion.
[0004] With the advancement of industrialization, some enterprises have introduced semi-automated equipment to assist in the production of skewed rotors. However, these devices still have significant shortcomings. Most of the equipment is designed only for a single type of skewed rotor. When market demand diversifies and requires the production of rotors with different specifications and skew angles, the existing equipment cannot quickly switch production modes. Enterprises have to purchase multiple sets of specialized equipment, which undoubtedly increases production costs and equipment maintenance difficulties. Moreover, the equipment has a high idle rate, resulting in resource waste. Therefore, it is necessary to improve the equipment. Utility Model Content

[0022] Example 1
[0023] Please see Figure 1-3 A slant rotor forming device for an electric motor includes a drive base 1, a placement slot 2 is provided on the top of the drive base 1, switching forming guide components are provided on both sides of the placement slot 2, and a compaction component is provided above the placement slot 2.
[0024] The switching forming guide assembly includes a switching column 4 rotatably connected to the top of the drive base 1. Multiple positioning columns 5 are provided on the outer side of the switching column 4. A positioning strip 6 is fixedly provided on the side of each positioning column 5 away from the switching column 4. The drive base 1 is provided with a linkage drive mechanism for driving the two switching columns 4 to rotate.
[0025] The positioning strip 6 is installed on the positioning post 5 at an angle, and the angle of the positioning strip 6 on different positioning posts 5 is different.
[0026] The compaction assembly includes a mounting bracket 7 fixedly mounted on the top of the drive base 1, a hydraulic cylinder 8 fixedly mounted on the mounting bracket 7, and the telescopic end of the hydraulic cylinder 8 fixedly connected to the pressure seat 9.
[0027] Furthermore, the linkage drive mechanism includes a drive motor 10 fixedly installed in the drive base 1. The output shaft of the drive motor 10 is coaxially fixedly connected to a drive gear 11. Each switching column 4 is coaxially fixedly connected to a drive rod. The drive rod extends into the drive base 1 and is coaxially fixedly connected to a passive gear 12. Both passive gears 12 are meshed with the drive gear 11.
[0028] Furthermore, multiple baffles 3 are fixedly provided on the drive base 1 outside the placement slot 2.
[0029] Furthermore, each positioning post 5 has a mounting groove 13 in the switching post 4 on one side. The mounting groove 13 is vertically arranged, and a mounting guide block 14 is fixedly provided on the side of the positioning post 5 near the mounting groove 13.

[0030] Furthermore, a vibration motor is provided on the drive base 1.
[0031] In the implementation of this utility model, multiple rotor chips are sequentially placed between two switching columns 4, so that the positioning strips 6 at the corresponding positions are engaged in the inclined grooves on the side of the rotor chips. Then, the vibration motor is started and the rotor chips gradually move down under the vibration of the vibration motor. After multiple rotor chips are placed in sequence, they will be stacked. When the rotor chips are stacked to the required number of layers, they will present the required inclined groove shape under the guidance of the positioning strips 6.
