Three-gear adjusting type variable-speed vertical and horizontal milling machine

The invention discloses a three-gear adjusting type variable-speed vertical and horizontal milling machine which comprises a supporting plate, a fixing assembly, a telescopic piece, a mounting block, an arc-shaped groove, a connecting rod, an elastic component, a buffering assembly, a pulley and a base. Under the action of pressure, a supporting plate moves downwards to compress an elastic component, then the pressure generated by vibration is buffered, the milling machine is well protected, the supporting plate moves downwards to drive a connecting rod to rotate, and the connecting rod drives a buffering assembly to operate when driving a pulley to slide on an arc-shaped groove; and pressure generated by vibration is further buffered through the buffering assembly, and the equipment is well protected. 本发明公开了一种三挡调节型变速立卧铣床，包括有支撑板、固定组件、伸缩件、安装块、弧形槽、连接杆、弹性部件、缓冲组件、滑轮和底座，铣床安装在支撑板上，通过固定组件将其固定限位，在运行时，会产生震动，在压力的作用下支撑板向下移动压缩弹性部件，进而缓冲震动产生的压力，对铣床有着很好的保护作用，支撑板向下移动进而带动连接杆转动，连接杆带动滑轮在弧形槽上滑动时带动缓冲组件运转，进而通过缓冲组件进一步的缓冲震动所产生的压力，对设
