Problems solved by technology

[0004] The suction cup panel is generally formed by arranging and stacking the magnetic guide sheet and the magnetic isolation sheet at intervals, and then fixing the magnetic guide sheet and the magnetic isolation sheet with a locking mechanism. Each component structure has a small movable space in the panel. Especially between the magnetic conductive sheet and the magnetic isolation sheet, due to the different magnetic adsorption force under the working / non-working state, it will be displaced or deformed due to the change of the magnetic force on the magnetic conductive sheet, which will aggravate the wear between the two
In addition, because the magnetic force received by the magnetic sheet is slightly shifted towards the direction of the magnetic source in the working state, the non-uniform contact between the panel and the adsorbed workpiece will cause non-uniform wear, and leakage of water and other liquids will easily occur during use. , which affects the performance and service life of the panel

Description

technical field [0001] The invention relates to a magnetic chuck device, in particular to a permanent magnetic chuck panel. Background technique [0002] Permanent magnetic chuck, also known as magnetic chuck, is a magnetic fixture widely used in machinery factories, mold factories, and other machining fields, which can greatly improve the clamping efficiency of magnetic steel materials. The permanent magnetic chuck is based on the high-performance rare earth material NdFeB (N>40), and the magnetic system of the NdFeB inside the chuck can be changed by turning the handle of the suction cup by hand to achieve the holding or releasing of the workpiece to be processed. The permanent magnetic chuck is designed by using the principle of continuity of magnetic flux and the principle of superposition of magnetic field. The magnetic circuit of the permanent magnetic chuck is designed into multiple magnetic systems. Elimination, so as to achieve the purpose of holding and unloadi...
