DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Combination Figure 1 , Figure 2 and Figure 3As shown, a cutting device for removing burrs from NdFeB magnets 7 includes a cutting machine for cutting NdFeB magnets 7 and a transmission mechanism 1 for transmitting NdFeB magnets 7. A deburring assembly 2 is arranged on the transmission mechanism 1. The deburring assembly 2 includes a support seat 3. An adjusting mechanism 4, a fixing mechanism 5 and a deburring mechanism 6 are installed on the support seat 3. The fixing mechanism 5 is used to fix the cut NdFeB magnets 7. The adjusting mechanism 4 is used to adjust the spacing of the fixing mechanism 5 according to the different lengths of the NdFeB magnets 7 after cutting. The deburring mechanism 6 is used to grind and remove the burrs on the NdFeB magnets 7. Specifically, the cutting device for removing burrs from NdFeB magnets is very cleverly and practically designed. The cutting machine is the main part of the device, which is used to accurately cut NdFeB magnets. The performance of the cutting machine directly affects the cutting quality and efficiency of the magnet, so it is very important to choose a high-performance and high-precision cutting machine. The transmission mechanism 1 is used to transmit the NdFeB magnet to be processed from one place to another, so as to facilitate the subsequent burr removal operation. The design of the transmission mechanism 1 should take into account the size, weight and stability of the magnet to ensure that the magnet will not be damaged or displaced during the transmission process. Deburring assembly 2 This is the core part of the device, including a support seat 3, an adjustment mechanism 4, a fixing mechanism 5 and a deburring mechanism 6. The support seat 3 provides stable support for the entire deburring assembly 2 to ensure that each mechanism can work normally. The adjustment mechanism 4 is used to adjust the spacing of the fixing mechanism 5 according to the different lengths of NdFeB magnets 7. This adjustment function is very practical because it can adapt the device to magnets of different sizes and improve the versatility and flexibility of the device. The fixing mechanism 5 is used to fix the cut NdFeB magnet 7 to prevent the magnet from moving or shaking during the deburring process. The design of the fixing mechanism 5 should take into account the characteristics of the magnet and the fixing method to ensure that the magnet can be firmly fixed. Deburring mechanism 6 This is the key part of deburring, and the burrs on the magnet are usually removed by grinding or cutting. The design of the deburring mechanism 6 should take into account the strength, speed and precision of grinding or cutting to ensure that the burrs can be completely removed without damaging the magnet itself. The design of this device fully considers the characteristics of the NdFeB magnet 7 and the need to remove burrs, and through reasonable mechanism configuration and adjustment function, efficient and accurate processing of the magnet is achieved. At the same time, the device also has the advantages of easy operation and good stability, which helps to improve production efficiency and product quality.

[0023] Combination Figure 2 , Figure 3 and Figure 4As shown, the adjusting mechanism 4 includes a first cylinder 4a fixedly mounted on the support seat 3, and an adjusting plate 4b is fixedly connected to the output end of the first cylinder 4a. Specifically, according to known information, the adjusting mechanism 4 plays a vital role in the cutting device for removing the burrs of the NdFeB magnet 7, and it is responsible for adjusting the spacing of the fixing mechanism 5 according to the NdFeB magnets 7 of different lengths after cutting. Now, the specific composition of the adjusting mechanism 4 is further described, which includes a first cylinder 4a fixedly mounted on the support seat 3, and an adjusting plate 4b fixedly connected to the output end of the first cylinder 4a. The first cylinder 4a acts as a power source, and drives the movement of the adjusting plate 4b through its telescopic movement. This design enables the adjusting mechanism 4 to accurately adjust the spacing of the fixing mechanism 5 according to actual needs. When it is necessary to process NdFeB magnets of different lengths, the position of the adjusting plate 4b can be changed by controlling the telescopic amount of the first cylinder 4a, thereby driving the fixing mechanism 5 to move accordingly to achieve the adjustment of the spacing. As a key component connecting the first cylinder 4a and the fixing mechanism 5, the stability and precision of the adjusting plate 4b are of vital importance for the whole adjusting process. Therefore, the adjusting plate 4b needs to be made of high-strength, high-precision materials to ensure that it can withstand the force of the cylinder and accurately transmit the motion. This design not only improves the flexibility and precision of the adjusting mechanism 4, but also makes the whole device easier to operate and maintain. By reasonably controlling the motion of the first cylinder 4a, effective processing of the NdFeB magnets 7 of different lengths can be achieved, thereby improving the working efficiency and application scope of the device.

[0024] Combination Figure 3 , Figure 4 and Figure 5As shown, the deburring mechanism 6 includes a servo motor 6a fixedly mounted on the adjustment plate 4b, and a grinding wheel 6b is fixedly connected to the output end of the servo motor 6a. Specifically, the design of the deburring mechanism 6 fully considers the actual needs of removing the burrs of the NdFeB magnet 7. It includes a servo motor 6a fixedly mounted on the adjustment plate 4b, and a grinding wheel 6b fixedly connected to the output end of the servo motor 6a. As the power source of the deburring mechanism, the servo motor 6a has the characteristics of high precision and high response speed. By accurately controlling the speed and direction of the servo motor 6a, the precise driving of the grinding wheel 6b can be achieved, thereby ensuring the effective removal of the burrs of the NdFeB magnet 7. The grinding wheel 6b is a direct tool for removing burrs, and the selection of its material and shape is crucial to the deburring effect. The grinding wheel 6b is usually made of wear-resistant and moderately hard materials to ensure a good grinding effect during long-term use. At the same time, the shape of the grinding wheel 6b also needs to be designed according to the shape of the NdFeB magnet 7 and the distribution of burrs to achieve the best grinding effect. The grinding wheel 6b is driven to rotate by the servo motor 6a, and the burrs on the NdFeB magnet 7 can be efficiently and accurately polished and removed. This design not only improves the efficiency and quality of deburring, but also reduces the difficulty of operation and labor costs. In addition, since the deburring mechanism 6 is installed on the adjustment plate 4b, it can move with the movement of the adjustment mechanism 4, thereby adapting to the deburring requirements of NdFeB magnets 7 of different lengths. This flexibility makes the entire device more suitable for large-scale and efficient magnet production lines.

[0025] Combination Figure 3 , Figure 4 and Figure 5As shown, the fixing mechanism 5 includes a second cylinder 5a installed at the bottom of the support seat 3, the output end of the second cylinder 5a is connected to a clamping jaw 5b, and the clamping jaw 5b is provided with a first anti-skid pad 5c. Specifically, the design of the fixing mechanism 5 ensures the stability and safety of the NdFeB magnet 7 during the burr removal process. The mechanism is mainly composed of a second cylinder 5a installed at the bottom of the support seat 3, a clamping jaw 5b connected to the output end of the second cylinder 5a, and a first anti-skid pad 5c provided on the clamping jaw 5b. The second cylinder 5a serves as the power source of the fixing mechanism, and its telescopic movement directly controls the opening and closing of the clamping jaw 5b. When the NdFeB magnet 7 needs to be fixed, the second cylinder 5a drives the clamping jaw 5b to close, thereby firmly clamping the magnet; when the processing is completed, the cylinder drives the clamping jaw 5b to open, which is convenient for taking out the magnet. This design is not only easy to operate, but also has a reliable fixing effect. As the part that directly contacts the magnet, the design of the clamping jaw 5b also fully considers anti-skid and stability. The clamping jaw 5b is made of appropriate material and structural design to ensure that the magnet can be firmly clamped during the clamping process to prevent it from sliding or falling off. At the same time, the shape and size of the clamping jaw 5b are also adapted to magnets of different sizes, which improves the versatility of the device. The provision of the first anti-skid pad 5c further enhances the anti-skid performance of the clamping jaw 5b. This anti-skid pad is made of a material with a high friction coefficient, which can increase the friction between the magnet and the magnet, thereby improving the stability of the clamping. The anti-skid pad can also protect the surface of the magnet and prevent damage to the magnet during the clamping process. In summary, the fixing mechanism 5 drives the opening and closing of the clamping jaw 5b through the second cylinder 5a, and the anti-skid effect of the first anti-skid pad 5c on the clamping jaw, thereby achieving stable and reliable fixation of the NdFeB magnet 7. This design not only improves the safety and efficiency of the deburring operation, but also ensures the integrity of the magnet during the processing process.

[0026] Combination Figure 3 , Figure 4 and Figure 5As shown, the transmission mechanism 1 includes a conveyor belt 1a, and brackets 1b are arranged on both sides of the conveyor belt 1a, and a second anti-skid pad 1c is arranged on the bracket 1b. Specifically, the transmission mechanism 1 is a key part to ensure that the NdFeB magnet 7 is smoothly and continuously transmitted to the deburring component 2 for processing. The mechanism is mainly composed of a conveyor belt 1a, a bracket 1b and a second anti-skid pad 1c, and each part plays an indispensable role. As the main transmission tool, the conveyor belt 1a is responsible for transporting the NdFeB magnet 7 to be processed from one place to another. The design of the conveyor belt 1a should take into account the size, weight and transmission speed of the magnet to ensure that the magnet can remain stable during the transmission process without deviation or falling. The bracket 1b is arranged on both sides of the conveyor belt, which plays a supporting and fixing role. The bracket 1b can effectively prevent the magnet from deviating from the conveyor belt 1a due to vibration or collision during the transmission process, ensuring the stability of the transmission. At the same time, the design of the bracket 1b also takes into account the shape and size of the magnet to adapt to magnets of different specifications. The second anti-skid pad 1c is arranged on the bracket 1b, and its function is similar to that of the first anti-skid pad 5c, both of which are to increase the friction between the magnet and the magnet to prevent the magnet from sliding or falling during the transmission process. The anti-skid pad is made of a material with a high friction coefficient, which can effectively improve the stability of the transmission. In summary, the transmission mechanism 1 realizes the stable and efficient transmission of the NdFeB magnet through the smooth transmission of the conveyor belt 1a, the support and fixation of the bracket 1b, and the anti-skid effect of the second anti-skid pad 1c. This design not only improves the working efficiency of the entire device, but also ensures the safety and integrity of the magnet during the transmission and deburring process.

[0027] Combination Figure 2 , Figure 3 and Figure 4As shown, the first anti-skid pad 5c and the second anti-skid pad 1c are both made of rubber material. Specifically, the first anti-skid pad 5c and the second anti-skid pad 1c are both made of rubber material, and this choice is based on the multiple advantages of rubber material. First, rubber has good anti-skid performance. Its surface friction coefficient is high, which can effectively increase the contact friction between the NdFeB magnet 7, thereby ensuring that the magnet is not easy to slide or fall off during fixation or transmission. Secondly, the rubber material has certain elasticity and toughness. This allows the anti-skid pad to deform to a certain extent when subjected to external force, better fit the surface shape of the magnet, and further improve the anti-skid effect. At the same time, the toughness of the rubber can also withstand a certain degree of stretching and compression, ensuring that the anti-skid pad maintains good performance in long-term use. In addition, rubber also has good wear resistance and durability. This allows the anti-skid pad to withstand long-term friction and wear and maintain a long service life. At the same time, the rubber material is relatively easy to process and shape, and can be made into anti-skid pads of different shapes and sizes according to actual needs to adapt to NdFeB magnets 7 of different specifications. In summary, the use of rubber material to make the first anti-skid pad 5c and the second anti-skid pad 1c not only ensures the anti-skid effect, but also takes into account durability and ease of processing. It is an effective measure to ensure the stability and safety of the NdFeB magnet 7 during fixation and transportation.

[0028] Combination Figure 2 , Figure 3 and Figure 4As shown, the support seat 3 is provided with a sliding groove 3a, and the bottom of the adjustment plate 4b is provided with a slider 4b1, and the adjustment plate 4b and the support seat 3 are connected in a sliding fit in the sliding groove 3a through the slider 4b1. Specifically, the sliding groove 3a provided on the support seat 3 and the slider 4b1 equipped at the bottom of the adjustment plate 4b together constitute a sliding fit connection mechanism. This design enables the adjustment plate 4b to slide accurately and smoothly on the support seat 3, thereby effectively adjusting the spacing of the fixing mechanism 5. The sliding groove 3a is used as a sliding track, and its shape and size are precisely designed to ensure that the slider 4b1 can slide smoothly therein. At the same time, the depth and width of the sliding groove 3a also take into account the weight and stability requirements of the adjustment plate 4b to prevent shaking or offset during the adjustment process. The slider 4b1 is fixed at the bottom of the adjustment plate 4b, and the selection of its material and shape also fully considers the sliding performance and stability. The surface of the slider 4b1 is specially treated to reduce the friction coefficient between it and the sliding groove 3a, thereby ensuring that the adjustment plate 4b can slide easily. At the same time, the connection between the slider 4b1 and the adjustment plate 4b is also reinforced to ensure that there will be no falling off or loosening during the adjustment process. Through this sliding fit connection mode, the adjustment mechanism 4 can accurately adjust the spacing of the fixing mechanism 5 according to the NdFeB magnets of different lengths. During the adjustment process, the adjustment plate 4b only needs to be pushed to slide in the sliding groove 3a by a driving mechanism (such as a cylinder) to achieve fast and accurate adjustment of the spacing. This design not only improves the accuracy and efficiency of the adjustment, but also simplifies the operation process and reduces labor costs.

[0029] Combination Figure 1 , Figure 2 and Figure 3As shown, the four corners of the bottom of the support base 3 are provided with legs 8. Specifically, the four corners of the bottom of the support base 3 are provided with legs 8, and this design plays a key supporting and stabilizing role in the entire device. First, the legs 8 can ensure that the support base 3 is placed stably on the ground or workbench to prevent the device from shaking or vibrating during operation, which may affect the accuracy and efficiency of deburring. The design of the legs 8 usually takes into account the flatness of the ground and the weight distribution of the device, ensuring that the support base 3 can stably carry the entire deburring assembly and other related components. Secondly, the height and length of the legs 8 can be adjusted as needed to adapt to different working environments and operating requirements. For example, when the device needs to be used on a workbench at different heights, the height of the legs 8 can be adjusted to ensure that the support base 3 reaches a suitable working position. In addition, the material and structure of the legs 8 are also carefully selected and designed to ensure that they have sufficient strength and stability to support the entire device. Usually, the legs 8 are made of sturdy and durable metal materials, which can withstand various forces and moments generated by the device during operation. In summary, the design of the legs 8 at the four corners of the bottom of the support seat 3 not only ensures the stability of the device, but also improves its adaptability and ease of use, and is an important component to ensure that the entire deburring device works efficiently and accurately.
