Grinding device with protection function

Abstract

The invention relates to a grinding device with a protection function. The grinding device comprises a base, a motor, a cam, a protection cover, a grinding wheel, a connecting column, a protection mechanism and a grinding mechanism, wherein the grinding mechanism comprises a fixing block and a grinding assembly, and the protection mechanism comprises a piston cylinder, a piston rod, spring strips,a pull rope, an abutting plate and a protection assembly. According to the grinding device with the protection function, the motor is protected through the protection mechanism, the pull rope is broken through the restoring force of springs, a control switch abuts against a metal sheet through the dead weight of the metal sheet, the motor is controlled to be turned off through a PLC to reduce loss, a cutter is ground through the grinding mechanism, and through an extended tool shank, heat generated by friction of the grinding wheel and the cutter is reduced, so that an operator can grind thecutter for longer; and meanwhile, the cutter is fixed through a bolt, so that when the operator loosens suddenly due to the fact that a connecting block is too hot, the cutter and the grinding wheel cannot be stuck, and the use practicability is improved.

Description

technical field [0001] The invention particularly relates to a grinding device with a protective function. Background technique [0002] Existing grinders for turning tools are generally operated by two grinding wheels at the same time, but two people are squeezed into a narrow space, so the operation is difficult and has certain dangers. When the operator grinds for a long time, The heat generated by the friction between the turning tool and the grinding wheel is transferred to the turning tool, causing the turning tool to become hot. When the turning tool accidentally falls into the grinding wheel, the operator's reaction must be to dodge, and then wait until there is no danger. To turn off the power, but this will lead to more serious damage to the grinding wheel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grinding device with a protective function in order to overcome the deficiencies of the prior art...
