Description

Technical Field

[0001] This utility model relates to the field of permanent magnet chuck technology, specifically a portable permanent magnet chuck. Background Technology

[0002] Permanent magnet chucks are a type of magnetic clamp widely used in the industrial field. They can improve the clamping effect on steel materials by conducting magnetism. Permanent magnet chucks can be designed into different shapes according to different usage needs. However, existing permanent magnet chucks still have certain defects in use. Traditional permanent magnet chucks are prone to problems of poor adsorption force and stability due to their small contact surface.

[0003] Patent CN212420509U discloses a novel permanent magnet chuck. The inner cavity of the annular permanent magnet chuck is fitted with a circular permanent magnet chuck. During magnetic attraction, the circular permanent magnet chuck contacts the relevant material, attracting it, while the annular permanent magnet chuck simultaneously attracts the top of the material, thus increasing the contact surface of the chuck and enhancing overall stability. A connecting block is fixedly installed on the circumferential outer wall of the circular permanent magnet chuck, and the connecting block is slidably connected to the circumferential outer wall of a corresponding fixed slide rod. The connecting block drives a movable push block to move towards a corresponding semi-circular pressing block, improving the overall stability of the movement. A spring-loaded fixing block pushes the movable push block towards the semi-circular pressing block, thereby increasing the mutual pressing force between the movable push block and the semi-circular pressing block. This makes the annular and circular permanent magnet chucks more stable during magnetic attraction. Compared with existing technologies, this represents an improvement in overall adsorption force and stability, greatly enhancing overall practicality.

[0004] In the aforementioned patent, the permanent magnet chuck solves the problems mentioned above. However, the permanent magnet chuck in this patent also has the following problems: during the use of the permanent magnet chuck, it is necessary to use an annular permanent magnet chuck and a circular permanent magnet chuck to adsorb steel metal parts. The annular and circular permanent magnet chucks are nested inside and outside, and the outer side of the permanent magnet chuck is smooth and flat. During use, it can only adsorb common metal parts. Furthermore, the adsorption range of the permanent magnet chuck is fixed and inconvenient, making it difficult to apply to adsorption in various situations. This greatly reduces the applicability of the permanent magnet chuck and easily affects the convenience of using the permanent magnet chuck.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing permanent magnet chuck structure. Utility Model Content

[0006] The purpose of this utility model is to provide a portable permanent magnet chuck to solve the problems mentioned in the background art, such as the smooth and flat outer surface of the permanent magnet chuck, which can only be used to attract common metal parts, and the fixed attraction range of the permanent magnet chuck, which makes it difficult to be used in various situations, thus greatly reducing the applicability of the permanent magnet chuck.

[0012] Preferably, a rotating screw is rotatably installed inside the magnetic panel, and the rotating screw is threadedly connected to the moving block. Furthermore, four sets of rotating screws, moving blocks, and magnetic slides are arranged at equal angles inside the magnetic panel.

[0013] Preferably, a secondary bevel gear is fixedly installed on the outer side of the rotating screw, and the secondary bevel gear meshes with the main bevel gear. The radius of the secondary bevel gear is smaller than that of the main bevel gear, and the secondary bevel gear is correspondingly arranged with the moving block.

[0014] Preferably, a threaded cylinder is fixedly installed at the lower end of the suction cup base, and a threaded rod is installed inside the threaded cylinder, and a square limiting frame is fixedly installed at the end of the threaded rod away from the threaded cylinder.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In a specific embodiment, such as Figures 1-2 and Figure 5 The hoisting process of the permanent magnet chuck is shown in the figure.

[0031] The suction cup base 1 and the connecting seat 2 connected to the upper end of the suction cup base 1; the connecting seat 2 is internally fitted with an embedded magnetic plate 3, and the connecting seat 2 is fixedly installed with a docking cylinder 4 at the end away from the suction cup base 1, and the docking cylinder 4 is internally provided with a magnetic coil 5, and the docking cylinder 4 is externally provided with an installation outer cylinder 6, and the installation outer cylinder 6 is fixedly installed with a magnetic panel 7 at the end away from the suction cup base 1.

[0032] A magnetic slide plate 8 and a moving block 12 are slidably mounted inside the magnetic panel 7. The moving block 12 and the magnetic slide plate 8 have mating holes 18 inside. The magnetic slide plate 8 is located outside the moving block 12. A main bevel gear 9 is rotatably mounted inside the upper end of the mounting outer cylinder 6. Threaded holes 17 are provided inside the mounting outer cylinder 6, the suction cup base 1, and the connecting seat 2. A mating rod 10 is fixedly mounted on the upper end of the connecting seat 2. The mating rod 10 is located inside the magnetic coil 5, and its upper end engages with the main bevel gear 9. The centerline of the mating rod 10 coincides with the centerlines of the mating cylinder 4 and the mounting outer cylinder 6. The maximum distance between the two sets of threaded cylinders 14 is less than the maximum distance between the two sets of threaded holes 17. The threaded cylinders 14 are evenly distributed at the lower end of the suction cup base 1.

[0033] When using this portable permanent magnet chuck, it needs to be installed in a designated position. The magnetic panel 7 can be installed on the upper end of the chuck base 1 or on the lower end of the chuck base 1. Before that, the square limiting frame 16 needs to be installed on the outside of the corresponding threaded cylinder 14. During this process, the threaded rod 15 needs to be threaded to the threaded cylinder 14, and the screw needs to be installed inside the threaded hole 17 to fix the chuck base 1, the connecting seat 2 and the mounting outer cylinder 6. The screw also needs to be installed inside the mating hole 18 to fix the magnetic slide plate 8 and the moving block 12. After that, the permanent magnet chuck can be limited by the square limiting frame 16 to complete the limiting process, and then the permanent magnet chuck can be used normally.

[0034] In one specific embodiment, such as Figures 1-8The specific usage process of the permanent magnet chuck is shown in the figure.

[0035] A rotating screw 11 is rotatably installed inside the magnetic panel 7, and the rotating screw 11 is threadedly connected to the moving block 12. The rotating screw 11, the moving block 12, and the magnetic slide plate 8 are arranged in four sets at equal angles inside the magnetic panel 7. A secondary bevel gear 13 is fixedly installed on the outside of the rotating screw 11, and the secondary bevel gear 13 meshes with the main bevel gear 9. The radius of the secondary bevel gear 13 is smaller than the radius of the main bevel gear 9. The secondary bevel gear 13 is correspondingly arranged with the moving block 12. A threaded cylinder 14 is fixedly installed at the lower end of the suction cup base 1, and a threaded rod 15 is threadedly installed inside the threaded cylinder 14. A square limiting frame 16 is fixedly installed at the end of the threaded rod 15 away from the threaded cylinder 14.

[0036] When using this portable permanent magnet chuck, the metal parts need to be magnetically moved by the magnetic panel 7 and the magnetic slide plate 8. During this process, the magnetic force of the magnetic panel 7 and the magnetic slide plate 8 needs to be enhanced by the magnetic coil 5, thereby increasing the stability of the metal parts during the moving process. In addition, the position of the magnetic slide plate 8 needs to be controlled during the use of the permanent magnet chuck to facilitate the permanent magnet chuck to attract different metal parts. During this process, after the connecting seat 2 is connected to the mounting outer cylinder 6, the connecting seat 2 is rotated. When the connecting seat 2 is connected to the mounting outer cylinder 6, the connecting rod 10 will engage with the lower end of the main bevel gear 9.

[0037] When the connecting seat 2 rotates, it drives the main bevel gear 9 to rotate. This causes the main bevel gear 9 to drive the secondary bevel gear 13, which is meshed with it on the outside, to rotate. The rotation of the secondary bevel gear 13 drives the rotating screw 11 to rotate, causing the moving block 12 to slide inside the magnetic panel 7. This causes the moving block 12 to drive the magnetic slide plate 8 to move. The movement of the magnetic slide plate 8 can expand the magnetic attraction area of ​​the permanent magnet chuck, thereby improving the ease of use of the permanent magnet chuck and increasing its overall practicality.

[0038] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
