AI Technical Summary
[0003]但是部分大型加工中心在上下料时，由于工件重量较大，需要悬臂吊机进行配合，现有的悬臂结构前端一般通过吊轮设置有吊绳，该吊轮通过轴销与悬臂连接，同时部分悬臂还通过轴销与液压缸连接，从而实现悬臂上下角度的调节，但是目前悬臂仅通过铰孔与轴销连接，导致悬臂与轴销连接处的结构强度不高，影响使用寿命，并且部分悬臂内部的支撑性也不加，影响稳定性，因此，亟待一种改进的技术来解决现有技术中所存在的这一问题
悬臂主体位于第一铰孔处设置有第一筒体，第一筒体外侧设置有若干第一加强板，缸体连接座的侧板位于第二铰孔处设置有第二筒体，第二筒体外侧设置有若干第二加强板，从而保证悬臂主体与销轴连接处的结构强度，从而提高使用寿命；悬臂主体内部两侧对称设置有若干侧加强板，两两侧加强板之间通过中间加强板相连，从而大大提高悬臂主体内部的支撑性及结构强度。

[0002] A machining center is a type of CNC machine tool with multiple functions. It integrates milling, boring, drilling, tapping, and thread cutting functions into one machine, enabling it to perform a variety of processes.
[0003] However, some large machining centers require cantilever cranes for loading and unloading workpieces due to their weight. Existing cantilever structures typically have a lifting rope attached to the front end via a wheel, which is connected to the cantilever via a pin. Some cantilever cranes are also connected to hydraulic cylinders via pins to adjust the vertical angle. However, currently, the cantilever is only connected to the pin via a hinge hole, resulting in low structural strength at the pin connection, affecting service life. Furthermore, the internal support of some cantilever cranes is insufficient, impacting stability. Therefore, an improved technology is urgently needed to address this problem in the existing technology. Summary of the Invention
