Sliding rod impact-type electric hammer

Abstract

The invention discloses a sliding rod impact-type electric hammer. The sliding rod impact-type electric hammer comprises an external casing, an electric hammer handle, a motor switch, a series machine, a hammer head vibrator, a hammer head, a rotor, striking sliding rods, a striking compression spring, a motor gear, a gear transmission shaft, a rotating shaft sleeve, a vibrator reset spring, a front sleeve and an arc-shaped energy storage slope. Through the mutual matching of the rotor, the striking sliding rod and the striking compression spring, the existing air cylinder impact is replaced by the striking sliding rod impact to achieve the sliding-rod-type electric hammer, the problem that an existing electric hammer often falls due to the prone damage of an air cylinder seal is solved, meanwhile a plurality of striking sliding rods are driven by the rotor to intermittently strike the hammer head vibrator, the technical effect that the series machine rotates one circle to impact the striking sliding rod for many times can be achieved, and the impact working efficiency of the electric hammer is improved.

Description

technical field [0001] The invention relates to the technical field of electric hammers and electric tools, in particular to a slide bar impact electric hammer. Background technique [0002] The electric hammer uses the principle of piston movement. The transmission mechanism drives the piston to reciprocate and compress the air in a cylinder. The periodic change of the air pressure in the cylinder drives the hammer in the cylinder to strike the top of the brick back and forth, just like we use a hammer to hit the brick. Electric hammer; [0003] For example, the Chinese utility model patent No. 2018203149420 discloses an electric hammer, which includes a reduction box body with a plastic box body and metal parts. The plastic box body has a relatively small density. At the same time, by setting metal parts, the metal parts have high supporting capacity and can bear large loads to ensure the supporting strength of the gearbox box, which not only greatly reduces the weight of...

Problems solved by technology

[0005] In view of the above-mentioned problems, the present invention realizes the sliding rod type electric hammer through the cooperation of the rotor, the striking slide bar and the striking compression spring, and replaces the impact of the existing cylinder with the impact of the striking slide bar. Damage causes the problem of frequent failure of the electric hammer. At the same time, the present invention drives a plurality of hitting sliders to hit the hammer vibrator intermittently through the rotor, which can realize the technical effect of hitting the slider for multiple times with the series excitation motor rotating one circle, and improves the electric hammer.
