Description

Technical Field

[0001] The utility model relates to the field of magnets, in particular to a multi-section assembled magnet. Background Art

[0002] Magnetic force is used in various fields of production, such as the automotive field, power generation field, and mold processing field. In the mold processing field, some iron parts cannot be fixed in place with screws or clamped with vises during the production process. In order to facilitate the fixing of these iron parts, a permanent magnetic chuck is usually used to fix the part position; the key to the permanent magnetic chuck being able to hold the workpiece after turning on the switch is the multi-segment assembled magnet located inside the permanent magnetic chuck switch and inside the permanent magnetic chuck. By adjusting the rotation direction of the switch, the magnetic poles of the magnet inside the permanent magnetic chuck are the same as the magnetic poles of the multi-segment assembled magnet inside the switch. Due to the principle of like poles repelling each other, the magnetic flux of the magnetic field of the multi-segment assembled magnet will break through the air gap and enter the workpiece to be adsorbed to form a closed magnetic circuit. At this time, the magnetic field inside the workpiece is opposite to the magnetic field of the multi-segment assembled magnet. According to the principle of opposite magnetic poles attracting each other, the workpiece will be adsorbed on the permanent magnetic chuck. When the magnetic poles of the magnet inside the permanent magnetic chuck are opposite to the magnetic poles of the multi-segment assembled magnet inside the switch, the two form an internal magnetic field loop, making its adsorption force insufficient to adsorb the workpiece.

[0003] Most of the existing multi-section assembled magnets are directly arranged by alternating N and S opposite poles to enhance the strength of the magnetic field. The magnet blocks are connected with magnetic glue, and then the assembled magnet group is placed inside the relevant equipment.

[0004] Although the strength of the magnetic field can be enhanced by connecting the oppositely charged magnets, each magnet is connected by magnetic glue, which makes it difficult to separate the magnet blocks because there is no gap between the magnets and they are fixed with glue. Utility Model Content

[0005] The technical problem to be solved by the utility model is that it is difficult to separate the magnet blocks of the existing multi-section assembled magnets during operation.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a multi-section assembled magnet, including a plurality of mutually attractive magnet blocks, iron plates are arranged between the magnet blocks, the magnet blocks and the iron plates form a closed-circuit magnet group, and a fixing frame device for fixing the closed-circuit magnet group is arranged around the closed-circuit magnet group, and the fixing frame device is made of non-magnetic material.

[0007] As an improvement, the upper and lower sides of the fixing frame device are provided with anti-collision pads to prevent collision.

[0008] As an improvement, the structure of the fixing frame device is a hollow frame.

[0009] As an improvement, the fixing frame device includes an open magnet assembly frame for storing the closed-circuit magnet assembly and an upper cover for closing the open magnet assembly frame.

[0010] As an improvement, the outer shape of the iron plate is larger than that of the magnet block, and the insides of the open magnet assembly frame and the upper cover are both provided with iron plate grooves for fixing the iron plate.

[0011] As an improvement, the open magnet assembly frame and the upper cover are connected by a copper bolt structure.

[0012] Compared with the prior art, the utility model has the following advantages: the device fixes the position of each magnet block by a fixing frame device, because the fixing frame devices are all made of non-magnetic materials, so that the loading and unloading of the fixing frame device will not be affected by the magnetic force, and by inserting an iron plate between each magnet block, a closed-circuit magnet group is generated (magnets directly attract iron at a small distance, and opposite polarities NS are alternately attracted to each other, at this time, the magnetic field is short, the magnetic resistance is small, and the suction force is maximum), while increasing the suction force, each magnet block is given a force point, and when the magnet blocks are separated, force can be applied to the iron plate, thereby saving effort and quickly separating each magnetic block.
