Description

Technical Field

[0001] The utility model relates to the field of magnetic attraction, in particular to an electric permanent magnetic chuck with adjustable angle. Background Art

[0002] The electric permanent magnetic chuck is a device that works on the principle of magnetic force. It uses electric pulses to realize the "opening and closing" of the magnetic circuit. It can be installed on milling machines, grinders, planers and other processing machines. Unlike traditional electromagnetic chucks, the electric permanent magnetic chuck does not need to generate a magnetic field by energizing the coil, but controls the strength of the magnetic force by controlling the on and off of the current. Therefore, it has the advantages of fast response speed, strong adsorption capacity, and adjustable magnetic force.

[0003] After searching, the Chinese patent announcement number: CN216371242U discloses a ring-shaped electric permanent magnetic chuck, including: a base; a plurality of chuck units, arranged on the base around the center of the base; a plurality of brushes, arranged on the base around the center of the base, and electrically connected to the plurality of chuck units one by one; and a slip ring, arranged at the center of the base, having at least two arc-shaped conductive tracks and at least two arc-shaped insulating tracks, and the plurality of brushes alternately contact the conductive tracks and the insulating tracks during the rotation of the base. When the workpiece rotates to the processing area, the brush connected to the chuck unit contacts one of the conductive tracks and then magnetizes the workpiece to adsorb it. When the workpiece is processed and rotated to the loading and unloading area, the brush of the chuck unit contacts another conductive track and then demagnetizes and releases the workpiece. At this time, the processed workpiece can be removed and the workpiece to be processed can be re-placed. The machine tool does not need to be stopped during the whole process, and continuous production can be achieved, thereby improving production efficiency. However, the utility model does not have the function of adjusting the angle. Some workpieces need to be processed at an inclined angle during processing, and the utility model cannot meet the processing requirements. Utility Model Content
