Clamping device for magnet grinding and magnet grinding equipment

Abstract

The invention discloses a clamping device for magnet grinding and magnet grinding equipment. The clamping device comprises a hollow rotary shaft, a rotary platform, clamping air cylinders, baffles, a magnet and a gas supply device. One end of the hollow rotary shaft is fixedly connected with a frame body. The rotary platform is mounted on the hollow rotary shaft through a bearing. The clamping air cylinders are mounted on the rotary platform. The baffles are connected with piston rods of the corresponding clamping air cylinders. The clamping air cylinders drive the baffles to clamp the magnet to be ground. The gas supply device is used for providing working gas for the clamping air cylinders; the gas supply device comprises a gas supply pipeline and a rotary gas joint. The rotary gas joint communicates the clamping air cylinders and the gas supply pipeline. The rotary gas joint is mounted in the hollow rotary shaft. By the adoption of the clamping device, the problem that when a permanent magnet is machined through a vertical shaft round-table surface grinding machine with an electromagnetic chuck, the magnet generates a low-intensity magnetic field due to the magnetic force generated by the electromagnetic chuck, and consequently great inconvenience is brought to following machining, transportation and surface antiseptic treatment is solved.

Description

technical field [0001] The invention belongs to the technical field of magnet grinding, and in particular relates to a clamping device for magnet grinding and magnet grinding equipment including the clamping device. Background technique [0002] Vertical axis circular table surface grinder is widely used in surface finishing due to its convenient operation and high efficiency of surface grinding. The usual workbench of this kind of processing equipment adopts the electromagnetic chuck to operate very conveniently. When the electromagnetic chuck is powered off, the magnetic force disappears to facilitate loading and unloading of workpieces; processing. [0003] However, when using a vertical axis round table surface grinder with an electromagnetic chuck to process permanent magnets (such as NdFeB magnets), the magnetic force generated by the magnetic chuck will cause the magnet to generate weak magnetism, which will have a huge impact on subsequent processing, transportation...
