Description

Technical Field

[0001] This utility model belongs to the field of magnet processing technology, and in particular relates to a high-speed cutting processing device for the inner hole of a magnet. Background Technology

[0002] In the magnet manufacturing industry, internal hole cutting is a crucial process widely used in electronics, machinery, aerospace, and many other fields to manufacture various magnetic components. The cutting quality of the magnet's internal hole directly affects the performance and precision of subsequent products. To meet the diverse needs of different industries for magnet internal hole dimensions and precision, efficient and precise cutting equipment is required to complete the task of cutting magnet internal holes.

[0003] Existing technologies, such as the automated manhole cutting device disclosed in CN222078302U, use a third servo motor to drive a second threaded rod to rotate, and then use clamping blocks to hold and fix the steel for cutting. However, this method has many drawbacks. First, its fixing method is mainly for steel. For special materials like magnets, due to their magnetic properties, traditional clamping block fixing methods may not guarantee the stability of the magnet during the cutting process, easily leading to a decrease in cutting accuracy. Second, this device only uses a single cutting method and does not consider factors such as the hardness and brittleness of the magnet material. During the cutting process, quality problems such as cracks and chipping are prone to occur. Furthermore, it does not solve the problems of cooling and chip removal during the cutting process, which may cause the magnet to demagnetize due to overheating, affecting product performance. In addition, this device is difficult to adapt to the cutting needs of magnet inner holes of different sizes, and its flexibility and adaptability are poor.

[0004] To address these issues, we provide a high-speed cutting device for the inner hole of a magnet. Utility Model Content

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, a movable guide rail 5 is fixedly connected to the top of the support plate 301, and a sliding groove is opened at the bottom of the movable plate 304 to cooperate with the movable guide rail 5.

[0031] Specifically: The cooperation between the moving guide rail 5 and the slide groove provides guidance and stability for the movement of the moving plate 304, ensuring that the fixing mechanism 3 can accurately and smoothly clamp the magnetic workpiece, further enhancing the stability and reliability of the fixing mechanism 3 and improving the fixing effect. The setting of the limiting hole and the limiting rod restricts the movement range of the connecting plate 308, ensuring that the connecting plate 308 can move along the predetermined trajectory when the electric telescopic rod 307 pushes the connecting plate 308, preventing it from moving excessively or deviating, thereby ensuring the stability and reliability of the fixing mechanism 3 and improving the function of the fixing mechanism 3. The diameter adjustment component 43, through the design of the threaded rod 432, the threaded sleeve 434 and the dual motor drive, can accurately adjust the height position of the cutting component 44 to meet the cutting requirements of the inner hole of magnets of different sizes, improving the adaptability and flexibility of the cutting device, and solving the problem that traditional cutting devices are difficult to adapt to the cutting of magnets of different sizes. The slide rod guides the movement of the threaded sleeve 434. The diameter adjustment component 43 and the waterjet cutting head 442 work together to ensure that the threaded sleeve 434 can move smoothly and accurately when adjusting the height of the cutting part 44, thus improving the accuracy of diameter adjustment and further optimizing the function of the diameter adjustment component 43. This ensures that the cutting part 44 can be accurately positioned. The design of the cutting part 44, combined with the laser emitter 443 and the waterjet cutting head 442, fully utilizes the advantages of laser preheating and waterjet cutting, achieving high-precision and high-speed cutting. At the same time, it solves the problems of cooling and chip removal during the cutting process, avoids magnet demagnetization, improves cutting quality and efficiency, and perfects the function of the cutting mechanism. The placement slot facilitates the placement of magnetic workpieces, improving the ease of operation. The baffle plate prevents water splashing during waterjet cutting, ensuring a clean working environment and improving the practicality of the device.

The control box 7 facilitates centralized control of the entire device, improving the ease of operation and the overall coordination of the device.

[0032] The working principle of this utility model is as follows: When the electric telescopic rod 307 extends, it pushes the connecting plate 308 forward, causing the second inclined plate 309 to contact and press against the first inclined plate 306. Through the force between the inclined plates, the moving plate 304 is pushed to move inward along the moving guide rail 5 at the top of the support plate 301, thereby driving the arc-shaped fixing plate 305 to clamp the magnet workpiece, achieving simultaneous fixation of both sides of the magnet and ensuring the stability of the magnet during processing. At the same time, the moving guide rail 5 at the top of the support plate 301 cooperates with the sliding groove at the bottom of the moving plate 304 to provide guidance and stability for the movement of the moving plate 304. The first motor 42 at the top of the top plate 41 drives the diameter adjustment component 43 and the cutting component 44 to rotate, realizing rotary cutting. When the second motor 433 starts... The rotation of the threaded rod 432 drives the threaded sleeve 434 to move axially along the threaded rod 432, thereby adjusting the height of the cutting part 44 to meet the cutting requirements of magnet inner holes of different sizes. The top of the fixing sleeve 441 of the cutting part 44 is fixed to the bottom of the threaded sleeve 434. A water jet cutting head 442 is installed on one side, and a laser emitter 443 is installed at the bottom. During cutting, the laser emitter 443 first emits a laser to preheat the inner hole of the magnet, reducing the hardness and brittleness of the magnet and reducing cracks and chipping during cutting. Then, the water jet cutting head 442 cuts under the guidance of the laser, improving cutting accuracy and speed. The water jet can also cool the magnet and remove cutting debris during the cutting process, preventing the magnet from demagnetizing due to overheating.
