Description

Technical Field

[0001] This utility model belongs to the field of motor magnet assembly technology, specifically relating to an installation structure for magnets. Background Technology

[0002] Motor magnets are a type of permanent magnet mainly used in permanent magnet motors. The motor magnets are assembled inside the motor tube. One existing installation method is to use spring steel supports or other rigid supports to open up the two ends of the magnets and fix them to the inner wall of the motor tube. This method requires a press and has a high installation cost.

[0003] Existing patent CN201821406146.6 describes a motor magnet assembly mechanism, comprising a base, a snap ring positioning mechanism fixed to the base, and a magnet limiting mechanism located above the snap ring positioning mechanism. The snap ring positioning mechanism includes symmetrically arranged snap ring positioning posts with their bottom ends fixed to the base, each post having a snap ring positioning groove. The magnet limiting mechanism includes a magnet mounting base, a magnet limiting seat fixed above the mounting base, and magnet limiting posts. The magnet limiting seat has symmetrically arranged magnet positioning grooves for positioning the magnets. The lower end of the magnetic tile is inserted into the magnetic tile positioning groove; the magnetic tile mounting base and the magnetic tile limiting base are respectively symmetrically provided with a first positioning post channel and a second positioning post channel located directly above the snap ring positioning post, which allow the snap ring positioning post to pass through when the magnetic tile mounting base and the magnetic tile limiting base move downward under the pressure of the motor housing. The first positioning post channel is provided with a snap ring guide groove that compresses and guides the two free ends of the snap ring. However, this assembly method also requires the use of a press, and the installation cost is high. Therefore, a new type of magnetic tile installation structure is designed to change the above-mentioned technical defects. Utility Model Content

[0022] This specific embodiment is an installation structure for magnetic tiles, and its structural diagram is shown below. Figures 1-5 As shown, the mounting structure includes a motor cylinder 1 and a magnetic tile 2 disposed inside the motor cylinder 1. A positioning component 3 for mounting the magnetic tile 2 is installed inside the motor cylinder 1. The positioning component 3 is provided with multiple mounting cavities 31. When the magnetic tile 2 is installed, it is aligned with the mounting cavity 31 and inserted into the positioning component 3, thus being installed inside the motor cylinder 1.

[0023] When installing the magnetic tile 2, align the magnetic tile 2 with the mounting cavity 31 on the positioning piece 3. Then, under the positioning action of the mounting cavity 31, the magnetic tile 2 can be directly installed. No press is required during the assembly process, and the installation process is simple. Specific Implementation

[0025] The positioning component 3 includes a positioning ring 32 and a positioning post 33 fixedly connected to the positioning ring 32. Both the positioning ring 32 and the positioning post 33 are made of plastic.

[0026] In addition, multiple positioning posts 33 are provided, and the multiple positioning posts 33 are arranged in a ring array and distributed at equal intervals on the positioning ring 32. An installation cavity 31 is formed between two adjacent positioning posts 33. Therefore, multiple installation cavities 31 are formed when there are multiple positioning posts 33, which can position and assemble the magnetic tiles 2 at different positions.

[0027] The positioning post 33 includes a guide part 331 and a positioning part 332. The side of the guide part 331 is an inclined surface, and the side of the positioning part 332 is a vertical surface.

[0028] Since the side of the guide part 331 is inclined, the distance between the guide parts 331 of two adjacent positioning posts 33 is slightly larger than that of the magnetic tile 2, which facilitates the insertion of the magnetic tile 2. During the process of inserting the magnetic tile 2 into the mounting cavity 31 formed by the two adjacent positioning posts 33, the magnetic tile 2 is easily guided into the mounting cavity 31 by the inclined surface of the guide part 331. After the magnetic tile 2 is inserted into the mounting cavity 31, the positioning ring 32 supports the magnetic tile 2. At the same time, the two sides of the magnetic tile 2 contact the positioning parts 332 of the two adjacent positioning posts 33 respectively, and the vertical side of the positioning part 332 positions the magnetic tile 2.

[0029] Both the guide part 331 and the positioning part 332 have a round hole in the middle. The round hole in the guide part 331 is connected to the round hole in the positioning part 332. The round hole in the guide part 331 and the round hole in the positioning part 332 are connected to form a fixing hole. The fixing hole is preferably a threaded hole. When the motor cylinder 1 is installed with the motor end cover, a through hole is opened at the position corresponding to the round hole on the motor end cover. The screw is tightened through the through hole into the fixing hole, which can fix the position of the guide part 331 and the positioning part 332, thereby fixing the positioning part 3 inside the motor cylinder 1. Then, the magnetic tile 2 is installed on the positioning part 3 to complete the assembly of the magnetic tile 2.

[0030] In summary, when installing the magnetic tile 2, the magnetic tile 2 is aligned with the mounting cavity 31 between two adjacent positioning posts 33, and then the magnetic tile 2 is inserted into the mounting cavity 31. During the insertion process, the magnetic tile 2 first passes through the guide part 331 to facilitate its entry into the mounting cavity 31. After the magnetic tile 2 enters the mounting cavity 31, the positioning ring 32 supports the magnetic tile 2, and at the same time, the two sides of the magnetic tile 2 contact the positioning parts 332 of the two adjacent positioning posts 33 respectively. The vertical side of the positioning part 332 positions the magnetic tile 2. At this point, the assembly of the magnetic tile 2 is completed. The assembly process does not require a press, and the assembly is simple and convenient. In addition, the assembly structure of this utility model is simple.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
