Description

Technical Field

[0001] This utility model belongs to the technical field of magnet processing equipment, specifically, it relates to a clamping device for magnet processing. Background Technology

[0002] In the existing technology, magnets need to be fixed with a clamp before they can be processed. Magnets are mainly available in two shapes: cylindrical and cubic. Different clamps are required for different types of magnets, either cylindrical or cubic.

[0003] Chinese Patent CN220719095U discloses a clamping device for magnet processing, belonging to the technical field of magnet processing equipment. It includes a frame, with a guide seat fixedly connected to the upper part of the frame. A slide is also slidably mounted on the upper part of the frame. A threaded control body is threadedly installed inside the slide. Slider blocks are symmetrically slidably connected inside both the slide and the guide seat. A limit block is fixedly connected to the outer end of each slider. Spring pieces are fixedly connected between the sliders. A leather piece is fixedly connected to each spring piece. Operating the threaded control body opens the slide, causing one set of sliders, limit blocks, and spring pieces to move away from another set of sliders, limit blocks, and spring pieces. A magnet block is placed between two spring pieces. Then, rotating the threaded control body in the opposite direction moves the slide backward, using the slide to drive the sliders to clamp the target magnet with the spring pieces.

[0004] The aforementioned comparative document describes a method where two spring tabs are placed on both sides of a magnet block. By rotating the threaded control body on one side, one of the spring tabs is driven to fix the magnet block located between the two spring tabs. However, the spring tabs are elastic. When the magnet block is large, since the two spring tabs do not fix the magnet block vertically, the magnet block may jump up when the two spring tabs exert a large force on it.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a clamping device for magnet processing.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A clamping device for magnet processing includes: a processing table, four movable plates slidably fitted on the processing table, horizontal clamping plates slidably fitted on the movable plates, a top clamping plate slidably fitted on the horizontal clamping plates, and a fixing component disposed inside the processing table;

[0009] The fixed assembly includes a rotating shaft rotatably fitted inside the processing table and a clamping plate set on the processing table. A first gear and a second gear are mounted on the rotating shaft. A sliding plate is mounted on the bottom of the moving plate, and a toothed plate is mounted on the bottom of the sliding plate. Two toothed plates are located on both sides of the first gear and mesh with it, and the other two toothed plates are located on both sides of the second gear and mesh with it. One of the moving plates is engaged with the clamping plate.

[0010] Optionally, a first threaded groove is provided on one side of the movable plate, and a first threaded rod is rotatably fitted on one side of the horizontal clamping plate. The first threaded rod is threaded into the first threaded groove. Slide rods are installed on opposite sides of the horizontal clamping plate, and through grooves are provided on opposite sides of the movable plate. The slide rods are slidably fitted into the through grooves. A sliding groove is provided on one side of the horizontal clamping plate, and a second threaded rod is rotatably fitted into the sliding groove. A slider is installed on one side of the top clamping plate, and the slider is slidably fitted into the sliding groove. A second threaded hole is provided on one side of the slider, and the second threaded rod is threaded into the second threaded hole. By rotating the first threaded rod, the horizontal clamping plate slides on the movable plate, which facilitates the clamping and fixing of magnet blocks of different shapes on the processing table. The slide rod on the horizontal clamping plate slides in the through groove of the movable plate, ensuring the stability of the horizontal clamping plate when moving and clamping. By rotating the second threaded rod, the top clamping plate moves up and down on the horizontal clamping plate, so that the top clamping plate can fix the magnet block in the vertical direction, reducing the possibility of the magnet block jumping up when the springs on both sides exert too much force on it.

[0011] Optionally, the processing table has a rotating groove inside, and a rotating shaft is rotatably fitted in the rotating groove. A spring is installed at the bottom of the rotating shaft, and the other end of the spring is installed at the bottom of the rotating groove. T-slots are opened on both sides of the moving plate, and the sliding plate and toothed plate are slidably fitted in the T-slots. A sliding groove is opened inside the processing table, and a clamping plate is located in the sliding groove. The sliding groove is located below one of the sliding plates, and a clamping block is installed at the bottom of one of the sliding plates. The clamping plate has multiple clamping slots, and the clamping block engages with the clamping slots. A connecting groove is opened at the bottom of the sliding groove, and a connecting post is installed at the bottom of the clamping plate. The connecting post is slidably fitted in the connecting groove, and a spring is sleeved on the connecting post. The spring is located between the bottom of the sliding groove and the clamping plate. When the processed magnet block on the processing table is loosened, the clamping plate is pushed down, causing the clamping slots on the clamping plate to move away from the clamping block and release the limit. This causes the rotating shaft to rotate in the opposite direction due to the force of the spring, thereby driving the four moving plates to move outward and open, making it easy to pick up the processed magnet block.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] The clamping device for magnet processing pulls one of the moving plates. Because the toothed plate meshes with the first and second gears, it drives the other three moving plates to slide outward simultaneously. At this time, the spring at the bottom of the rotating shaft is in a wound state, and the clamping plate fixes one of the moving plates, ensuring that all four moving plates are in an open state, making it easy to place the magnet block on the processing table. By operating the clamping plate, the limit of the moving plates is released, and the force of the spring drives the four moving plates to move towards the magnet block. The horizontal clamping plate and the top clamping plate on the moving plates clamp and fix the magnet block.

A spring 7 is mounted on the bottom of the rotating shaft 6, and the other end of the spring 7 is mounted on the bottom of the rotating groove 23.

[0026] One application of this embodiment is as follows: When clamping the magnet block, by pulling one of the moving plates 2, the toothed plate 11 meshes with the first gear 8 and the second gear 9, thereby driving the other three moving plates 2 to slide outward simultaneously. At this time, the spring at the bottom of the rotating shaft 6 is in a wound state, and the clamping plate 5 fixes one of the moving plates 2, ensuring that the four moving plates 2 are in an open state, which makes it easy to place the magnet block on the processing table 1. By operating the clamping plate 5, the limit of the moving plate 2 is released, and the force of the spring 7 drives the four moving plates 2 to move towards the magnet block. The horizontal clamping plate 3 and the top clamping plate 4 on the moving plate 2 clamp and fix the magnet block.

[0027] In this embodiment, a first threaded groove 12 is provided on one side of the movable plate 2, and a first threaded rod 14 is rotatably fitted on one side of the horizontal clamping plate 3.

The second threaded rod 17 is threaded into the second threaded hole 19. By rotating the first threaded rod 14, the horizontal clamping plate 3 is driven to slide on the moving plate 2, which facilitates the clamping and fixing of magnet blocks of different shapes on the processing table 1. The sliding rod 15 on the horizontal clamping plate 3 slides in the through groove 13 of the moving plate 2 to ensure the stability of the horizontal clamping plate 3 when moving and clamping. By rotating the second threaded rod 17, the top clamping plate 4 is driven to move up and down on the horizontal clamping plate 3, so that the top clamping plate 4 can fix the vertical direction of the magnet block and reduce the possibility that the magnet block may jump when the springs on both sides exert too much force on it.

[0028] In this embodiment, T-slots 20 are provided on both sides of the movable plate 2. The sliding plate 10 and the toothed plate 11 are slidably fitted in the T-slots 20.
