[0028] This utility model provides a magnetic pole polishing machine.
[0029] The following examples illustrate the implementation of magnetic pole polishing machines.
[0030] Please refer to Figures 1 to 2 In one embodiment of this utility model, a magnetic pole polishing machine includes:
[0031] Workbench 10;
[0032] The mounting adjustment device 20 includes a mounting base assembly 21 and a sliding assembly 22. The mounting base assembly 21 is mounted on the sliding assembly 22, and the sliding assembly 22 is slidably disposed on the worktable 10. The mounting base assembly 21 has a mounting part 211 for mounting a sanding belt.
[0033] The rotating fixing device 30 includes a rotating component 31, which is used to place a magnetic pole. When the rotating component 31 rotates, it drives the magnetic pole to rotate and contact the sanding belt.
[0034] The rotating assembly 31 includes a rotating shaft 311 and a base 312. The base 312 is disposed on the worktable 10, the rotating shaft 311 is disposed on the base 312, and the magnetic pole is sleeved on the rotating shaft 311. When the rotating shaft 311 rotates, it can drive the magnetic pole to contact the sanding belt in the circumferential direction.
[0035] The magnetic pole grinder also includes a tensioning mechanism 40, which is elastically connected to the sliding component 22. When the sliding component 22 slides on the worktable 10, the tensioning mechanism 40 undergoes elastic deformation to adjust the horizontal distance between the sliding component 22 and the rotating component 31.
[0036] The sliding assembly 22 includes a slide rail 221, a slider 222, and a locking member 223. The slide rail 221 is disposed on the worktable 10. The slider 222 is slidably connected to the slide rail 221. The mounting base assembly 21 is disposed on the slider 222. One end of the slider 222 is elastically connected to the tensioning mechanism 40, and the other end of the slider 222 is connected to the locking member 223. The locking member 223 is used to lock the locking member 223 on the slide rail 221 after the position of the slider 222 is adjusted.
[0037] This utility model proposes a design scheme for a magnetic pole grinding machine, which is mainly used for grinding the surface of magnetic poles. The worktable 10 serves as the basic support structure of the entire equipment. The mounting and adjusting device 20 includes a mounting base assembly 21 and a sliding assembly 22. The mounting base assembly 21 has a mounting part 211 for mounting the sanding belt, and its position can be adjusted on the worktable 10 via the sliding assembly 22. This allows the position of the sanding belt to be flexibly adjusted as needed to adapt to the grinding requirements of magnetic poles of different sizes and shapes. The rotating component 31 in the rotating fixing device 30 is used to place and rotate the magnetic pole. When the rotating component 31 drives the magnetic pole to rotate, the surface of the magnetic pole will contact the fixed sanding belt, generating friction to complete the grinding process. This design ensures that all sides of the magnetic pole can be evenly ground by the sanding belt. Specifically, the magnetic pole to be ground is first fixed on the rotating component 31. According to the size and shape of the magnetic pole, the position of the mounting base assembly 21 is adjusted by the sliding assembly 22 to ensure that the sanding belt can effectively contact the surface of the magnetic pole. When the equipment is started, the rotating component 31 begins to rotate, driving the magnetic poles to rotate, and the abrasive belt also begins to work. Through rotation and movement, friction is generated between the surface of the magnetic poles and the abrasive belt, completing the grinding operation. By combining the rotating fixing device 30 and the mounting adjustment device 20, the equipment can handle magnetic poles of various sizes and shapes, increasing its versatility and flexibility.
[0038] Specifically, the rotating assembly 31 consists of a rotating shaft 311 and a base 312. The base 312 is fixed on the worktable 10, the rotating shaft 311 is mounted on the base 312, and the magnetic poles are sleeved on the rotating shaft 311. When the rotating shaft 311 rotates, it drives the magnetic poles to make circumferential contact with the sanding belt for grinding. The rotating shaft 311 is the key component that directly contacts and drives the magnetic poles to rotate. By sleeved on it, the magnetic poles are ensured to remain stable and effectively contact the sanding belt during rotation. The base 312 provides a robust mounting foundation, allowing the rotating shaft 311 to be stably mounted on it and ensuring stability during rotation. Specifically, first, the magnetic poles to be ground are sleeved on the rotating shaft 311 and secured. According to the size and shape of the magnetic poles, the position of the mounting base assembly 21 is adjusted by the sliding assembly 22 to position the sanding belt in the appropriate working position. The equipment is started, and the rotating shaft 311 begins to rotate, driving the magnetic poles to rotate at a certain speed. At the same time, the sanding belt also begins to work. As the rotating shaft 311 rotates, the magnetic poles come into circumferential contact with the abrasive belt, generating friction to polish the surface of the magnetic poles. After polishing, the equipment is stopped, and the polished magnetic poles are removed. The rotating design and adjustable mounting structure ensure uniform force on the magnetic pole surface, reducing errors caused by manual intervention and improving polishing quality and efficiency. By flexibly adjusting the position of the abrasive belt and using rotating shafts of different specifications, the equipment can handle magnetic poles of various sizes and shapes. This reduces the risk of operators directly contacting high-speed rotating components and improves work safety. Understandably, the rotating shaft 311 needs to be inserted into a pre-set bearing or support structure in the base 312. These support structures (such as rolling bearings) allow the rotating shaft 311 to rotate smoothly and reduce friction and energy loss. Alternatively, the rotating shaft 311 can be connected to a drive system (such as a motor) to provide rotational power.
[0039] The position of the abrasive belt is adjusted via the sliding assembly 22 according to the specific size and shape of the magnetic poles. During this process, the tensioning mechanism 40 elastically deforms according to the movement of the sliding assembly 22, automatically adjusting the horizontal distance between the sliding assembly 22 and the rotating assembly 31 to ensure the abrasive belt is always in the optimal working position. If further adjustment of the contact angle or pressure between the abrasive belt and the magnetic poles is required during grinding, this can be achieved by continuing to slide the sliding assembly 22. At this time, the tensioning mechanism 40 continues to function, maintaining appropriate tension and distance to ensure the stability and consistency of the grinding process. The design of the tensioning mechanism 40 allows the sliding assembly 22 to flexibly adjust its position according to magnetic poles of different sizes and shapes, increasing the equipment's adaptability to different types of workpieces. Through elastic connection, the tensioning mechanism 40 can automatically adjust the tension as the sliding assembly 22 moves, avoiding stress concentration problems caused by rigid mechanical connections and improving the overall stability of the system. The tensioning mechanism 40 ensures that the abrasive belt maintains appropriate tension throughout the grinding process, preventing the abrasive belt from becoming too loose or too tight, and contributing to a more uniform and high-quality grinding result. Understandably, the tensioning mechanism 40 can be a spring-type tensioner, using the spring force to maintain the tension of the sanding belt. Springs of different strengths and lengths can be selected according to different needs. It can also be a pneumatic or hydraulic tensioner, adjusting the tension through gas or liquid pressure. Alternatively, it can be a screw-adjustable tensioner, adjusting the position of the tensioning wheel by rotating a screw.
[0040] Specifically, the slide rail 221 is fixed to the worktable 10, serving as the basic track for the sliding of the slider 222. The slider 222 is slidably connected to the slide rail 221, allowing free movement along the slide rail 221. The mounting bracket assembly 21 is fixed to the slider 222, thus allowing it to move with the slider 222. The locking member 223 is used to lock the slider 222 onto the slide rail 221 after it has been adjusted to the appropriate position, preventing displacement of the slider 222 during operation. One end of the tensioning mechanism 40 is elastically connected to the support base 41, and the other end is elastically connected to one end of the slider 222, providing necessary elastic support. Specifically, the magnetic pole to be ground is sleeved on the rotating shaft 311 and fixed using a limiting member or a limiting device. The operator manually pushes the slider 222 to slide along the slide rail 221 to adjust the position of the sanding belt relative to the magnetic pole. During this process, the compression spring 42 deforms (compresses or stretches) according to the movement of the slider 222, automatically adjusting the horizontal distance between the slider 222 and the rotating assembly 31 to ensure the sanding belt is in the proper working position. The drive unit 33 is activated (e.g., by manually turning the handle), causing the rotating shaft 311 to rotate, driving the magnetic poles to rotate. The sanding belt also begins to work; as the rotating shaft 311 rotates, the magnetic pole surface contacts the sanding belt, generating friction for polishing. During polishing, if further adjustment of the contact angle or pressure between the sanding belt and the magnetic poles is needed, this can be achieved by continuing to slide the slider 222. At this time, the compression spring 42 continues to function, maintaining appropriate tension and distance to ensure the stability and consistency of the polishing process. After adjustment, the locking member 223 is used to lock the slider 222 onto the slide rail 221 to prevent accidental movement during operation. After polishing is complete, the drive unit 33 is stopped, the locking member 223 is released, and the polished magnetic poles are removed. The combination of slide rail 221, slider 222 and locking element 223 enables precise control of the sanding belt position, and the elastic support provided by tensioning mechanism 40 ensures stability and consistency during the sanding process.
[0041] Please refer to Figures 1 to 2 In one embodiment of the present invention, the rotating fixing device 30 further includes a limiting member 32 and a connecting bolt. The magnetic pole is located between the limiting member 32 and the rotating shaft 311. The connecting bolt passes through the limiting member 32 and is threadedly connected to the rotating shaft 311 to position the magnetic pole on the rotating shaft 311.
[0042] A limiting member 32 is located between the magnetic pole and the rotating shaft 311 to restrict the position of the magnetic pole and prevent it from sliding or shifting during rotation. A connecting bolt passes through the limiting member 32 and is threaded onto the rotating shaft 311 to further reinforce the position of the magnetic pole and ensure it remains stationary throughout the grinding process. This design allows for fine-tuning according to different magnetic pole sizes to ensure optimal fixation. Specifically, the magnetic pole to be ground is fitted onto the rotating shaft 311, and the limiting member 32 is placed on one side of the magnetic pole to initially fix its position. Then, the connecting bolt passes through the limiting member 32 and is threaded onto the rotating shaft 311, tightly clamping the magnetic pole between the limiting member 32 and the rotating shaft 311. Depending on the specific size and shape of the magnetic pole, the position of the mounting base assembly 21 is adjusted via the sliding assembly 22 to position the sanding belt in the appropriate working position for effective contact with the magnetic pole surface. The design of the limiting member 32 and the connecting bolt ensures the stability of the magnetic pole during high-speed rotation, preventing loosening or shifting of the magnetic pole due to vibration or rotation. The position and force of the limiting component 32 can be adjusted according to the different sizes and shapes of magnetic poles to ensure that various types of magnetic poles can be firmly fixed. Understandably, the limiting component 32 can take various forms, depending on the actual application requirements and technical specifications. The limiting component 32 can be a flange-type limiting component: a flange-like structure that can better distribute pressure by increasing the contact area, suitable for larger or heavier magnetic poles. It can also be a clamp-type limiting component, fixing the magnetic pole by tightening the clamp, which is simple to use and facilitates quick magnetic pole replacement. Alternatively, it can be an embedded limiting component, designed as a small structure that can be embedded inside the magnetic pole, suitable for applications requiring high-precision positioning.
[0043] Please refer to Figures 1 to 2 In one embodiment of the present invention, the rotating fixing device 30 further includes a driving member 33, which is drivenly connected to the rotating shaft 311 to drive the rotating shaft 311 to rotate.
[0044] The drive component 33 is driven by the rotating shaft 311, providing rotational power to the shaft. Through this drive connection, the drive component 33 enables the rotating shaft 311 and its magnetic poles to rotate at the required speed and torque. Directly driving the rotating shaft 311 with the drive component 33 allows for precise control of rotational speed and torque, thereby improving grinding efficiency and quality. Different drive components can be selected with different transmission methods (such as belt drive, gear drive, etc.) to adapt to different power and speed requirements.
[0045] Please refer to Figures 1 to 2 In one embodiment of the present invention, the driving component 33 includes a handle, which is connected to the end of the rotating shaft 311 away from the sanding belt.
[0046] The drive element 33 is a handle connected to the end of the rotating shaft 311 furthest from the sanding belt. This design allows the operator to manually rotate the rotating shaft 311 to drive the magnetic poles to rotate, thereby performing the sanding operation. Using a handle as the drive method eliminates the need for an electric motor or other complex power transmission systems, reducing equipment costs and maintenance requirements. For some small, lightweight applications, manual drive provides sufficient control precision and adjustment range, facilitating fine-tuning according to specific conditions.
[0047] Please refer to Figures 1 to 2 In one embodiment of the present invention, the tensioning mechanism 40 includes a support base 41 and a compression spring 42. One end of the compression spring 42 is elastically connected to the support base 41, and the other end of the compression spring 42 is elastically connected to the sliding component 22.
[0048] In this embodiment, the tensioning mechanism 40 specifically consists of a support base 41 and a compression spring 42. This design, through an elastic connection, provides the necessary elasticity and tension adjustment when the sliding component 22 is adjusted, ensuring optimal contact between the sanding belt and the magnetic poles. The support base 41 is fixed on the worktable 10, serving as the basic support point for the entire tensioning mechanism 40. One end of the compression spring 42 is elastically connected to the support base 41, and the other end is elastically connected to the sliding component 22. The main function of the compression spring 42 is to provide appropriate elasticity according to the positional changes of the sliding component 22, thereby automatically adjusting the horizontal distance between the sliding component 22 and the rotating component 31 and maintaining appropriate tension on the sanding belt. The design of the tensioning mechanism 40 allows the sliding component 22 to flexibly adjust its position according to different sizes and shapes of the magnetic poles, increasing the equipment's ability to handle different types of workpieces. Through the elastic connection, the compression spring 42 can automatically adjust the tension when the sliding component 22 moves, avoiding stress concentration problems caused by rigid mechanical connections and improving the overall stability of the system. Operators can more easily adjust the position of the sanding belt, quickly finding the appropriate grinding position without complicated calibration steps, thus improving work efficiency. The compression spring 42 ensures that the sanding belt maintains proper tension throughout the sanding process, preventing the sanding belt from becoming too loose or too tight, and helping to obtain more uniform and high-quality sanding results.
[0049] Please refer to Figures 1 to 2 In one embodiment of the present invention, the mounting base assembly 21 includes a mounting base 212, the mounting base 212 having a recessed mounting portion 211, the mounting base 212 having a first inclined surface and a second inclined surface arranged opposite to each other, the first inclined surface being disposed toward the magnetic pole, the second inclined surface being disposed toward the tensioning mechanism 40, and the magnetic pole contacting the sand belt on the first inclined surface during rotation.
[0050] Mounting base 212 has a first inclined surface facing the magnetic pole, on which the sanding belt is mounted, allowing the sanding belt to form an optimal contact angle with the rotating magnetic pole surface. A second inclined surface faces the tensioning mechanism 40, helping to maintain appropriate tension on the sanding belt and ensuring it doesn't become too tight or slack throughout the polishing process. The design of the first inclined surface optimizes the contact angle between the sanding belt and the magnetic pole, ensuring effective contact between the sanding belt and the magnetic pole surface during polishing, improving polishing efficiency and quality. The compression spring 42 and the design of the second inclined surface work together to ensure the sanding belt maintains appropriate tension throughout the polishing process, preventing it from becoming too tight or slack, and contributing to a more uniform and high-quality polishing result. Placing the sanding belt in the mounting portion 211, which is recessed into the mounting base 212, allows for accurate positioning of the sanding belt and maintains stability with appropriate tension. Specifically, the operator manually pushes the slider 222 along the slide rail 221 to adjust the position of the sanding belt relative to the magnetic pole. During this process, the compression spring 42 deforms (compresses or stretches) according to the movement of the slider 222, automatically adjusting the horizontal distance between the slider 222 and the rotating assembly 31 to ensure the sanding belt is in the proper working position. The drive unit 33 is activated (e.g., by manually turning the handle), causing the rotating shaft 311 to rotate, driving the magnetic poles to rotate. The sanding belt also begins to work; as the rotating shaft 311 rotates, the magnetic pole surface contacts the sanding belt, generating friction for polishing. At this time, the magnetic pole surface contacts the sanding belt on the first inclined surface of the mounting base 212, forming the optimal polishing angle and pressure distribution. During polishing, if further adjustment of the contact angle or pressure between the sanding belt and the magnetic pole is needed, this can be achieved by continuing to slide the slider 222. At this time, the compression spring 42 continues to function, maintaining appropriate tension and distance to ensure the stability and consistency of the polishing process.
[0051] Please refer to Figures 1 to 2 In one embodiment of the present invention, the mounting portion 211 has one or more grooves located on the outer surface of the mounting portion 211, and the grooves are used to mount the sanding belt.
[0052] The sanding belt is placed in the groove of the mounting portion 211. The groove design allows the sanding belt to be accurately positioned and kept stable with appropriate tension. This precise positioning reduces installation errors and ensures optimal contact angle and pressure distribution between the sanding belt and the magnetic pole. The groove provides additional support for the sanding belt, preventing slippage or displacement during high-speed rotation, thus improving the overall stability of the system. Operators can more easily install and replace the sanding belt, quickly finding the appropriate mounting position without complex calibration steps, improving work efficiency. In some embodiments, multiple grooves are designed, allowing selection of the appropriate groove to accommodate sanding belts of different widths or types as needed.
[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
