Sliding rail mechanical arm device

The utility model discloses a sliding rail mechanical arm device. X-axis sliding rail, a Y-axis slide rail, a mechanical arm and a rotating shaft seat, the Y-axis sliding rail is perpendicular to theX-axis sliding rail. The Y-axis sliding rail horizontally moves in a horizontal concave rail groove of the X-axis sliding rail through a driving wheel at the lower end; the X-axis sliding rail is fixed on the horizontal rotating shaft seat; angle rotation in a range of 360 degrees is realized through the rotation of the rotating shaft seat; the mechanical arm comprises a front arm rod and a rear arm rod. One end of the rear arm rod is connected with the front arm rod in a shaft rotating mode. A first hydraulic arm rod driving device is arranged on one side of the shaft rotating joint of the front arm rod, the other end of the rear arm rod is connected with an inner core sliding block in the Y-axis sliding rail, a second hydraulic arm rod driving device is arranged on one side of the jointof the rear arm rod and th
