Abstract

The invention provides a spring compression and quick release cycle impact structure and belongs to the field of electric tools. The spring compression and quick release cycle impact structure comprises two threaded rods, an impact rod, linear grooves, a guiding-out structure and a guiding-in structure. The threaded rods are connected with a driving mechanism and can rotate synchronously under the effect of the driving mechanism. The two ends of the impact rod are limited in thread pitch grooves of the threaded rods; the impact rod moves backwards with rotation of the threaded rods and is connected with an elastic structure; and when the impact rod moves backwards, the elastic structure is compressed to accumulate potential energy. The linear grooves are fixed relative to a shell; and one end of the impact rod penetrates the corresponding linear groove and is used for limiting the impact rod from breaking away from the interior of the thread pitch groove of the corresponding threaded rod. The guiding-out structure is in butt joint with the rear ends of the linear grooves; when the impact rod moves to the rear ends of the linear grooves, the guiding-out structure pushes one end of the impact rod out of the corresponding thread pitch groove and the corresponding linear groove; and after being free from limitation, the impact rod impacts forwards under the effect of the push force of the elastic structure. The guiding-in structure is in butt joint with the front ends of the linear grooves; and the impact rod impacts to the front ends of the linear grooves under the effect of the elastic potential energy and re-guided into the thread pitch grooves through the guiding-in structure.

Description

technical field [0001] The invention belongs to the field of electric tools, and relates to an impact tool or an impact test bench, in particular to a spring compression quick release cycle impact structure and an impact method. Background technique [0002] Electric tools or testing equipment need to have impact structures, such as electric hammers, electric picks, etc. [0003] The impact structure of the existing electric tool is mainly driven by the impact of the cam structure, the stroke of this structure is small, and the power required to convert the kinetic energy is too large. [0004] There is also an impact structure that releases elastic potential energy through a spring, but this structure appears to be slow during the spring extrusion process, and cannot achieve the purpose of rapid impact. Contents of the invention [0005] The object of the present invention is to provide a spring compression quick release cyclic shock structure and shock method to solve t...
