Anti-interference electric hammer capable of being applied to strong magnetic field environment

Abstract

The invention relates to the field of electric tools, in particular to an anti-interference electric hammer capable of being applied to a strong magnetic field environment, which comprises a shell, a first motor, a second motor and a controller are arranged in the shell, a worm on an output shaft of the first motor is meshed with an eccentric shaft gear, and a connecting rod on an eccentric shaft of the eccentric shaft gear is connected with a piston in an air cylinder. An impact hammer, a firing pin and a drill bit are sequentially arranged on the other side of the piston, and a compensation coil is arranged on the firing pin; the eccentric shaft gear drives a chain wheel, a second driven gear and the like to rotate the cylinder; a driving gear on an output shaft of the second motor is meshed with a gear of the eccentric shaft, a demagnetizer capable of being movably taken out is arranged above the second motor, magnetic shielding covers are arranged on the outer sides of the first motor and the controller, the first motor is a brushless motor and adopts a sensorless reversing algorithm, a shell is made of a non-magnetic material, a piston is made of a ceramic piston, and a gear is made of a titanium alloy gear. The technical effects that the electric hammer can be normally used in the high-intensity magnetic field environment, magnetic field interference is reduced, and stable operation of the electric hammer is guaranteed are achieved.
