Casting-forging type hinge of hollowed-out structure
The invention discloses a casting-forging type hinge of a hollowed-out structure, and relates to the technical field of hinges. The problems that during drilling after an existing universal casting orforging type hinge is formed, axis skewing easily happens, so that the yield is small are solved. The casting-forging type hinge of the hollowed-out structure comprises a hinge plate. One end of thehinge plate is fixedly connected to the side face of a hinge shaft. The hinge shaft is composed of an upper shaft body and a lower shaft body, a mounting hole is machined in a turnover secondary machining manner during shaft hole drilling operation, the axis skewing condition is reduced, the yield is increased, in cooperation with the design of a hollowed-out hole, the dead weight of the device isreduced, no machining amount exists in the middle during shaft hole machining, the diameter-depth ratio of the machined hole is reduced, the axis skewing condition can be completely eradicated, the yield is greatly increased, and the practicality and the adaptability of the device are improved.
本发明公开了一种镂空结构的铸锻式铰链，涉及铰链技术领域，解决了现有的通用式铸造或锻造式铰链成型后钻孔加工时易出现轴线歪斜问题，导致良品率较低的问题。一种镂空结构的铸锻式铰链，包括铰链板；所述铰链板的一端固定连接在铰链轴的侧面。铰链轴由上轴体和下轴体组成，在钻轴孔操作时采用翻面二次加工方式加工安装孔，减少轴线歪斜情况，提高良品率，配合镂空孔的设计，降低了该装置的自重，在轴孔加工时中部无加工量，减小了加工孔的径深比，可完全杜绝轴线歪斜情况，大幅提高了良品率，提高了该装置的实用性和适应性。
