Positioning structure of a board breaking machine

This utility model relates to a positioning structure for a plate breaking machine, including a frame mounted on the plate breaking machine. The frame is equipped with several symmetrically distributed supporting shells, positioning components, pressing blocks, and feeding components. This positioning structure, by incorporating supporting shells, positioning components, and pressing blocks, with both the pressing blocks and the force-bearing blocks designed for inclined surface contact, utilizes the force decomposition characteristics of the inclined surface to convert the vertical force output by the hydraulic cylinder into the horizontal force required by the positioning plate. Furthermore, it decomposes the reaction force of the positioning plate into forces acting on the supporting shells and forces acting on the hydraulic cylinder, preventing the hydraulic cylinder from directly bearing excessive horizontal reaction force. This force direction conversion reduces the load on the hydraulic cylinder, preventing metal fatigue and malfunctions caused by prolonged operation. Moreover, the spring's rebound potential energy drives the positioning plate to automatically reset, requiring no additional power and simplifying the control logic of the release action.
