Description

Technical Field

[0001] This utility model relates to the field of disc motor processing technology, specifically to a disc motor rotor that is easy to assemble. Background Technology

[0002] Traditional magnet fixing processes face several technical bottlenecks that urgently need to be overcome. From an implementation perspective: First, conventional adhesive fixing methods require additional devices such as cover plates and protective sleeves, resulting in complex installation processes, high maintenance costs, and high adhesive costs. Second, to achieve uniform magnet distribution, specialized positioning fixtures must be developed, significantly increasing production preparation costs. More seriously, in the installation of pre-magnetized magnets, due to the millimeter-thickness and strong magnetic attraction of the components, current manual operation methods pose significant safety hazards—operators are highly susceptible to pinching injuries during the grasping and positioning process. Statistics show that this process consistently ranks among the top three most dangerous operations in the industry. This current state of affairs not only affects production efficiency but also poses a severe challenge to enterprise safety management. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a disc motor rotor that is easy to assemble.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a disc motor rotor that is easy to assemble, comprising an annular rotor core and magnets. Its innovation lies in: a ring of mounting holes is formed on the upper part of the rotor core; the mounting holes are stepped holes; the magnets are placed inside the mounting holes; sliding grooves are formed on the left and right sides of the mounting holes; sliding pressure blocks are provided within the sliding grooves; through holes are formed on the pressure blocks; threaded holes are formed within the sliding grooves; the pressure blocks move towards the magnets to press them down, and the through holes and threaded holes overlap, and are fixed using bolts.

[0005] Furthermore, the sidewall of the chute is provided with a guide strip, and the sidewall of the pressure block is provided with a guide groove, the guide groove and the guide strip cooperating with each other.

[0006] Furthermore, the bottom front end of the pressure block is chamfered, and a rubber pad is embedded in the bottom.

[0007] Furthermore, the through hole is a countersunk hole.

[0008] Furthermore, the upper surface of the pressure block is lower than or flush with the surface of the rotor core.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows:

[0010] This invention uses a clamping block to fix the magnet, making installation convenient and quick. It also facilitates replacement when a magnet is damaged, resulting in easy and low-cost maintenance. Furthermore, this invention eliminates the need for tooling, further reducing costs and improving work efficiency. It also effectively avoids the dangers associated with magnet installation.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0017] See Figure 1 A conveniently assembled disc motor rotor includes an annular rotor core 1 and magnets 2. A ring of mounting holes 3, which are stepped, is formed on the rotor core 1. The magnets 2 are placed within the mounting holes 3. Sliding grooves 4 are formed on the left and right sides of the mounting holes 3. Sliding pressure blocks 5 are installed within the sliding grooves 4. Through holes 51 are formed on the pressure blocks 5, and threaded holes 6 are formed within the sliding grooves 4. The pressure blocks 5 move towards the magnets 2, pressing them down, with the through holes 51 and threaded holes 6 overlapping. Bolts are used for fixing. Specifically, the magnets 2 are placed in the mounting holes 3, and the pressure blocks 5 are moved above the magnets 2, pressing them down. The through holes 51 and threaded holes 6 overlap, and bolts are used for fixing. This installation method is convenient and quick. Furthermore, when a magnet is found to be damaged, it is easy to replace, making maintenance convenient and cost-effective. This invention does not require tooling, further reducing costs and improving work efficiency. It also effectively avoids the dangers of magnet installation.

[0018] In this embodiment, guide strips are provided on the sidewalls of the slide 4, and guide grooves are formed on the sidewalls of the pressure block 5. The guide grooves and guide strips cooperate with each other. The pressure block 5 slides through the guide strips and guide grooves, while also being limited in position.

[0019] See Figure 2The front end of the pressure block 5 is chamfered 52, and a rubber pad 53 is embedded in the bottom. The chamfer 52 facilitates the movement of the pressure block 5 to the surface of the magnet, while the rubber pad 53 can prevent damage to the magnet and increase the tightening force when the bolt is tightened.

[0020] In this embodiment, the through hole 51 is a countersunk hole to hide the bolt.

[0021] In this embodiment, the upper surface of the pressure block 5 is lower than or flush with the surface of the rotor core to avoid interference during the assembly of the disc motor and affect the assembly process.

[0022] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
