Abstract

The invention provides a vibration electric hammer, wherein a drill sleeve is fixedly mounted at a front end of a cylinder body; an impacting hammer is mounted on a proper position on a rear part of the drill sleeve; a compression spring is mounted the proper position of a drive piston; the drive piston and the compression spring are mounted in the cylinder body at the back of the drill sleeve; an air hole is arranged on an upper surface of an outer circle of the cylinder body; the drive piston can seal the air hole at a free state; large bevel gears are fixedly mounted at the proper position of the cylinder body; the large bevel gears, small bevel gears, large gears, small gears and a motor sequentially form a drive chain relationship; the piston is mounted at the proper position at the back of the cylinder body; a connecting rod iron core is connected with the piston via a pin shaft; and an electromagnet is fixedly mounted in a shell at the proper position at the back of the cylinder body.

Description

technical field [0001] The invention relates to an electric hammer, in particular to a vibrating electric hammer, which belongs to the technical field of electric tools. Background technique [0002] Because the vibrating electric hammer can generate a certain vibration impact force while drilling, it has a good drilling and cutting effect for some difficult-to-drill materials. At present, the principle of the impact force of the vibrating electric hammer is to rely on high-speed rotation This method of using mechanical impact to generate impact force has the following disadvantages: first, the structure is complicated due to the need for a corresponding mechanical transmission mechanism; secondly, due to the mechanical impact The force acts on the cam and the transmission mechanism, so the electric hammer transmission mechanism is easily damaged and the service life is low; again, because the cam has a certain amount of eccentricity when rotating, the hand feels a large vib...
