Supporting and machining all-in-one machine equipment special for railway contact net

The invention discloses supporting and machining all-in-one machine equipment special for a railway overhead line system. The current situation problem that a cantilever supporting and positioning supporting component in an existing railway overhead line system is not provided with integrated machining special equipment is solved. The all-in-one machine equipment is provided with a 90-degree corner, a machining station comprises a first machining area and a second machining area, a clamping unit, a feeding mechanism, a drilling unit and a milling unit are installed on the first machining area, and a blunt chamfering unit is installed on the second machining area. When the correlation type photoelectric sensor senses that a workpiece enters, the double-shaft air cylinder extends to an initial original point, and the pressure sensor on the surface of the positioning block senses the workpiece, an action signal is sent out, so that the pressing assembly and the clamping assembly act, the workpiece is tightly hel
