Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a magnetic grinder. Background Art

[0002] Magnetic grinding machines are innovative solutions that address the shortcomings and drawbacks of traditional grinding machines. Compared to traditional methods, they are more effective in addressing hard-to-reach areas such as inner holes, corners, and tiny crevices on precision hardware workpieces, significantly improving polishing and deburring. These machines utilize a magnetic field to attract and apply stainless steel grinding pins to the workpiece. This high-frequency rotational motion produces a powerful grinding effect. This not only quickly removes burrs and dirt from the workpiece surface, but also improves the surface finish, ensuring the quality of the final product.

[0003] Existing magnetic grinding machines typically use a motor to drive the rotation of a magnetic pole block, which drives the magnetic material in the grinding barrel to grind and polish the workpiece. For example, Chinese patent publication No. CN211073135U discloses a "magnetic grinding machine" in which a second hydraulic cylinder drives a first motor to slide on a support plate, adjusts the spacing between the first and second disks, and adjusts the height of the first and second disks via the first hydraulic cylinder. The first and second disks are adjusted to the optimal grinding position for different workpieces, thereby improving grinding efficiency. A protective shell prevents debris from splashing during the grinding process.

[0004] In actual use, in order to make the grinding barrel correspond to the grinder, a mounting slot or protective shell is usually set to position the grinding barrel. However, the total weight of the grinding liquid, magnetic abrasive and workpiece in the grinding barrel is large. When the workers remove the grinding barrel after processing, they first move the grinding barrel up and out of the mounting slot, which is extremely laborious and increases the burden on the workers. Some magnetic grinders use circles drawn on the processing table for marking, which is convenient for matching with the grinding barrel. However, in actual use, the workpiece in the grinding barrel rotates faster as the grinding time increases, making the center of gravity of the grinding barrel unstable and moving away from the marked position, causing the internal workpiece to collide with the grinding barrel and be damaged. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art of positioning the grinding barrel with an installation groove or a protective shell, which makes it inconvenient to remove the material, and the circle for marking corresponds to the grinding barrel, and the grinding barrel is easily moved away from the marked position during processing, causing the internal workpiece to collide with the grinding barrel and cause damage. A magnetic grinding machine is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A magnetic grinding machine is designed, comprising a processing table, a mounting groove for mounting a grinding barrel is provided on the processing table, a driving structure is provided in the processing table, a support frame is provided in the mounting groove, a support plate that cooperates with the grinding barrel is provided on the support frame, and a lifting mechanism that cooperates with the support plate is provided on the support frame;

[0008] The driving structure includes a first motor, an output shaft of the first motor is fixedly provided with a mounting plate, a magnetic pole block is provided on the mounting plate, and the magnetic pole block and the mounting plate are connected via a connecting structure.

[0009] Furthermore, the lifting mechanism includes a second motor fixedly arranged in the support frame, the output shaft of the second motor is fixedly connected to a screw rod, and the support plate is provided with a threaded hole threadedly connected to the screw rod.

[0010] Furthermore, an extension portion is fixedly provided on the support plate, the threaded hole is provided on the extension portion, a threaded sleeve corresponding to the screw rod is fixedly provided on the lower end of the extension portion, and a socket matching the threaded sleeve is provided on the support frame.

[0011] Furthermore, a through groove cooperating with the extension portion is formed on the mounting groove, and a guide rod cooperating with the extension portion is fixedly provided on the support frame.

[0012] Furthermore, a support frame is fixedly provided in the processing table, an annular groove is provided on the support frame, and a support portion that matches the annular groove is fixedly provided on the mounting plate.

[0013] Furthermore, the connection structure includes a slide groove opened on the mounting plate, a slider matching the slide groove is fixedly provided on the magnetic pole block, a double-headed screw threadedly connected to the two sliders is rotatably provided in the slide groove, and a knob is fixed on the double-headed screw.

[0014] The magnetic grinding machine proposed in this utility model has the following beneficial effects:

[0015] In the present invention, the grinding barrel is positioned by the mounting groove to prevent the workpiece inside the grinding barrel from rotating faster as the grinding time increases, causing the center of gravity of the grinding barrel to become unstable and move away from the marked position, thereby avoiding the workpiece inside the grinding barrel from colliding with the grinding barrel and causing damage;

[0016] Secondly, in the present invention, a support frame is provided opposite to the installation groove, and a lifting structure is provided on the support frame. After the processing is completed, the support plate and the grinding barrel are lifted by the lifting structure, which makes it convenient for workers to remove the grinding barrel for unloading.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-5 A magnetic grinding machine includes a processing table 1, a mounting groove 2 for mounting a grinding barrel is provided on the processing table 1, a driving structure 3 is provided in the processing table 1, a support frame 4 is provided in the mounting groove 2, a support plate 5 that cooperates with the grinding barrel is provided on the support frame 4, and a lifting mechanism 6 that cooperates with the support plate 5 is provided on the support frame 4;

[0025] The driving structure 3 includes a first motor 31 . A mounting plate 32 is fixedly provided on the output shaft of the first motor 31 . A magnetic pole block 33 is provided on the mounting plate 32 . The magnetic pole block 33 and the mounting plate 32 are connected via a connecting structure.

[0026] In the present invention, the grinding barrel is positioned by the mounting groove 2 to prevent the workpiece in the grinding barrel from accelerating as the grinding time increases, causing the center of gravity of the grinding barrel to become unstable and move away from the marked position, thereby avoiding the workpiece inside the grinding barrel from colliding with the grinding barrel and causing damage. By providing a support frame 4 opposite to the mounting groove 2 and providing a jacking mechanism 6 on the support frame 4, the support plate 5 and the grinding barrel are lifted by the jacking mechanism 6 after the processing is completed, which makes it convenient for workers to remove the grinding barrel for unloading.

[0027] Furthermore, in this embodiment, the lifting mechanism 6 includes a second motor 61 fixedly arranged in the support frame 4, the output shaft of the second motor 61 is fixedly connected to the screw rod 62, and a threaded hole threadedly connected to the screw rod 62 is opened on the support plate 5. The screw rod 62 is driven to rotate by the second motor 61, driving the support plate 5 to move up and down, driving the grinding barrel to move up and down, thereby facilitating unloading.

[0028] Furthermore, in this embodiment, an extension portion 51 is fixedly provided on the support plate 5, a threaded hole is provided on the extension portion 51, a threaded sleeve 52 corresponding to the screw rod 62 is fixedly provided on the lower end of the extension portion 51, and a socket that cooperates with the threaded sleeve 52 is provided on the support frame 4. When unloading, the support plate 5 and the threaded sleeve 52 move upward, driving the grinding barrel to move upward until the support plate 5 coincides with the upper surface of the processing table 1, and the grinding barrel can be removed, eliminating the step of workers moving the grinding barrel upward, which is more convenient, and the threaded sleeve 52 cooperates with the screw rod 62 to prevent the support plate 5 from separating from the screw rod 62.

[0029] It should be noted that, in this embodiment, a through groove 53 is provided on the mounting groove 2 and cooperates with the extension portion 51, and a guide rod 54 is fixedly provided on the support frame 4 and cooperates with the extension portion 51. When the support plate 5 coincides with the upper surface of the processing table 1, the extension portion 51 coincides with the through groove 53, and the guide rod 54 cooperates with the extension portion 51 to limit the rising trajectory of the support plate 5, thereby reducing the force strength of the screw rod 62.

[0030] In addition, in this embodiment, a support frame 7 is fixedly installed in the processing table 1, and an annular groove 71 is opened on the support frame 7. A support portion 72 that cooperates with the annular groove 71 is fixedly installed on the mounting plate 32. The support portion 72 cooperates with the annular groove 71 on the support frame 7 to share the force applied to the first motor 31 and reduce the burden on the first motor 31.

[0031] In more detail, in this embodiment, the connection structure includes a slide groove 321 provided on the mounting plate 32, a slider 322 that cooperates with the slide groove 321 is fixedly provided on the magnetic pole block 33, a double-headed screw 323 that is threadably connected to the two sliders 322 is rotatably provided in the slide groove 321, and a knob 324 is fixedly provided on the double-headed screw 323. By turning the knob 324, the double-headed screw 323 can be driven to rotate, thereby adjusting the position of the two magnetic pole blocks 33, which is suitable for the processing of different workpieces and improves the scope of application. In some embodiments, the knob 324 can also be a double-headed motor.

[0032] Working method: During operation, the grinding barrel is positioned through the mounting groove 2, and the magnetic pole block 33 is driven to rotate by the first motor 31, driving the magnetic material in the grinding barrel to grind the workpiece. After the grinding is completed, the screw rod 62 is driven to rotate by the second motor 61, driving the extension part 51 and the support plate 5 to move upward, and the grinding barrel is driven to move upward by the support plate 5 until the support plate 5 coincides with the upper surface of the processing table 1. The grinding barrel can then be removed, eliminating the step of workers moving the grinding barrel upward, making unloading more convenient.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
