Detailed Implementation
[0014] The present invention will now be further described with reference to the accompanying drawings.
[0015] like Figures 1 to 13As shown, a high-attraction magnetic base includes a base body 1, an isolator 2, a rotating column 6, a first magnet 4, a second magnet 5, and a handle 74. The base body 1 has a rotating hole 12 and an isolating groove 13. The rotating hole 12 is located at one end of the base body 1, and the isolating groove 13 is arranged along the axis of the rotating hole 12 of the base body 1. The isolating groove 13 is a through groove, which enables the base body 1 to form two independent magnetic conductors 11. The two magnetic conductors 11 are symmetrically arranged. The isolator 2 is fixed in the isolating groove 13 and forms an integral structure with the base body 1. The isolator 2 is U-shaped, and the isolator 2 enables the base body 1 to form two independent magnetic conductors 11. The isolator 2 is made of a non-magnetic material, such as copper, aluminum, or engineering plastics, while the base body 1 is made of a soft magnetic material, such as cast iron or iron. The first magnet 4 and the second magnet 5 are installed on both sides of the rotating column 6, with one magnet 4 and the other magnet 5 corresponding to each other. The total number of the first magnet 4 and the second magnet 5 can be two, four, six, etc. The rotating column 6 is rotatably installed in the rotating hole 12, and the first magnet 4 and the second magnet 5 are rotatably located in the rotating hole 12. The magnetic poles of the first magnet 4 and the second magnet 5 facing the base 1 are different. The handle 74 is fixed to one end of the rotating column 6 and is located outside one end of the base 1, used to drive the rotating column 6 to rotate. When the adsorption is opened, the first magnet 4 and the second magnet 5 are respectively arranged opposite to the two magnetic conductors 11, so that the magnetic lines of force pass through the workpiece and form a closed circuit on the two magnetic conductors 11. When the adsorption is closed, the first magnet 4 and the second magnet 5 are both arranged opposite to the two magnetic conductors 11 at the same time, so that the magnetic lines of force form a closed circuit inside the two magnetic conductors 11.
[0016] The magnetic pole of the first magnet 4 facing the rotating hole 12 is the S pole, and the magnetic pole of the first magnet 4 fixed on the rotating column 6 is the N pole. The magnetic pole of the second magnet 5 facing the rotating hole 12 is the N pole, and the magnetic pole of the second magnet 5 fixed on the rotating column 6 is the S pole, so that the magnetic poles of the first magnet 4 and the second magnet 5 facing the rotating hole 12 are different, and the magnetic poles formed by the existing magnetic base are the same. The magnetic poles of the first magnet 4 and the second magnet 5 facing the rotating hole 12 are not fixed; the first magnet 4 can also have the N pole facing the rotating hole 12, and the second magnet 5 can have the S pole facing the rotating hole 12, as long as the magnetic poles facing the rotating hole 12 are different.
[0017] When there is one first magnet 4 and one second magnet 5, they are symmetrically located on both sides of the rotating column 6. When there are two first magnets 4 and two second magnets 5, each side of the rotating column 6 is equipped with two first magnets 4 and two second magnets 5, and the first magnets and the second magnets are arranged in a ring.
[0018] When the first magnet 4 and the second magnet 5 are located on both sides of the isolator 2, so that the two magnetic conductors 11 form different magnetic poles, they play an adsorption role. The bottom of the magnetic conductor 11 generates magnetic force and can be adsorbed onto the workpiece.
[0019] The structure of seat 1 is basically the same as the existing seat structure, ensuring versatility.
[0020] When the first magnet 4 and the second magnet 5 are simultaneously positioned opposite to the two magnetic conductors 11, closed magnetic lines of force are formed inside the two magnetic conductors 11. The magnetic conductors 11 have no attraction force on the workpiece, and the magnetic seat can be removed.
[0021] Because the number of magnets used is 2, 4, or 6 times that of existing magnetic bases, the magnetic force can be greatly improved. While keeping the size the same, the attraction force is increased. For example, for a magnetic base with a size of 50×55×64mm, the existing magnetic base has an attraction force of about 80 kg, while the attraction force is about 180 kg when four magnets are used, which can ensure the reliability and stability of use.
[0022] To facilitate processing, stabilize the magnetic force, and obtain the maximum magnetic force, the first magnet 4 and the second magnet 5 are symmetrically arranged on both sides of the rotating column 6.
[0023] To facilitate the fixing of the magnets, symmetrical fixing grooves 63 are provided on both sides of the rotating column 6, and the fixing grooves 63 are respectively connected to the first magnet 4 and the second magnet 5. The first magnet 4 and the second magnet 5 can be fixed in the fixing grooves 63 by means of screws or glue.
[0024] To facilitate the positioning of the handle 74, the high-attraction magnetic base also includes a positioning device. This device is located on the base body 1 and the rotating column 6, and is used to limit the opening and closing positions of the handle 74. Specifically, the positioning device includes a positioning post 71 and a positioning block 61. The positioning post 71 is installed in a limiting hole 14 at the top of the base body 1, with the limiting hole 14 located at the top of the rotating hole 12. The positioning block 61 is located at the top of the rotating column 6 and is integral with it. The positioning block 61 is movably positioned within the limiting hole 14. The positioning block 61 has a positioning surface 62, which is opposite to the positioning post 71. When rotating to the opening position, the positioning post 71 abuts against one end of the positioning surface 62; when rotating to the closing position, the positioning post 71 abuts against the other end of the positioning surface 62. The positioning post 71 and the positioning surface 62 limit the rotation position of the handle 74, allowing the operating base to sense whether the rotating column 6 and the magnet have rotated to the set position.
[0025] To improve the reliability and stability of the axial positioning of the rotating column 6, the high-attraction magnetic seat also includes a positioning sleeve 72. The positioning sleeve 72 is fixed on the limiting hole 14. The interior of the positioning sleeve 72 is provided with a rotating groove 721 that matches the positioning block 61. The positioning block 61 is located in the rotating groove 721 and can be annular. The positioning block 61 is located in the limiting hole 14 and between the seat body 1 and the positioning sleeve 72, thus achieving axial positioning and preventing axial movement.
[0026] To reduce friction between the rotating column 6 and the bottom of the rotating hole 12, making the rotating column 6 rotate more flexibly and keeping its axis unchanged, the high-attraction magnetic base also includes a rotating ring 75. The rotating ring 75 is installed at the bottom of the rotating hole 12, and the bottom of the rotating column 6 has a rotating shaft 66, which is rotatably mounted on the center hole of the rotating ring 75. The rotating ring 75 can be made of copper or engineering plastic.
[0027] To facilitate observation of the working status of the high-attraction magnetic base, the high-attraction magnetic base also includes an indicator ring 73. The indicator ring 73 is provided with an open mark and a close mark. The indicator ring 73 is installed on the top of the positioning sleeve 72 and is movably sleeved on the rotating column 6. The open mark and the close mark are set opposite to the handle 74.
[0028] The top of the rotating column 6 is provided with a regular polygonal connecting column 64, and the handle 74 is provided with a regular polygonal connecting hole. The connecting column 64 is inserted into the connecting hole, so that the handle 74 can drive the rotating column 6 to rotate.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
