The present invention relates to an automatic machining device for a high-speed rail pantograph carbon contact strip and a machining method therefor. The automatic machining device is sequentially provided with a milling position, a sawing position and a chamfering position, and comprises a rack, a band sawing machine, a workpiece milling device, a workpiece chamfering device, a CNC computer numerical control system and a pneumatic system. A carbon contact strip workpiece to be machined is arranged on the rack and is sequentially subjected to milling, sawing and chamfering machining; and a saw frame of the band sawing machine is also provided with a saw band upper guide servo rotating device and a saw band lower guide servo rotating device, and the saw band upper guide servo rotating device and the saw band lower guide servo rotating device can freely, synchronously and correspondingly rotate a band saw blade within a certain range. In the present invention, a carbon contact strip is machined by means of a sawing mode, the processes of sawing, milling and chamfering are integrated on one device, and the processes of milling, sawing and chamfering can be automatically completed after once clamping, thereby saving materials, and increasing the working efficiency. |
