Problems solved by technology

The disadvantage of the currently used knocking device is that when the movable shaft moves up and down in the hole of the fixed plate, there is sliding friction between the outer wall of the movable shaft and the fixed plate, and the friction coefficient is relatively large, thereby reducing the force of the knocking head. percussion force

Embodiment Construction

[0011] The knocking device of the present invention will be further described in detail through specific embodiments below.

[0012] Such as figure 1 As shown, a knocking device includes a movable shaft 1, the lower end of the movable shaft 1 is provided with a striking head 2, the upper end of the movable shaft 1 is provided with a limit plate 3, and the outer sleeve of the movable shaft 1 is provided with a linear bearing 4. The lower end of the linear bearing 4 is provided with a steel gasket 5, and the movable shaft 1 between the striking head 2 and the linear bearing 4 is provided with a spring 6, wherein the limit plate 3 is used to prevent the movable shaft 1 from moving downward. , the movable shaft 1 falls out from the linear bearing 4.

[0013] The working principle of the present invention is: when in use, the movable shaft 1 moves up and down in the linear bearing 4 through the action of an external force, and the knocking head 2 strikes the material as the movabl...

Abstract

The invention relates to a knocking device. The knocking device comprises a movable shaft, wherein the lower end of the movable shaft is provided with a knocking head; the upper end of the movable shaft is provided with a limiting plate; and a linear bearing is sheathed outside the movable shaft. The knocking device is applicable to knocking materials, and compared with the knocking device used at present, the knocking device provided by the invention has the advantage that the knocking force of the knocking head is increased.

Description

technical field [0001] The invention relates to a knocking device for knocking materials. Background technique [0002] The knocking device is one of the common tools used to knock the material so as to make the internal structure of the material tighter. The structure of the currently used percussion device includes a fixed plate, a hole is arranged in the fixed plate, a movable shaft is penetrated in the hole, a percussion head is arranged at the lower end of the movable shaft, and a movable shaft between the percussion head and the fixed plate is arranged. The shaft is provided with a spring, and the upper end of the movable shaft is provided with a limiting plate. When in use, the movable shaft moves up and down in the hole of the fixed plate through the action of external force, and the knocking head strikes the material with the up and down movement of the movable shaft, so that the internal structure of the material is more compact, and the movable shaft moves upward...
