Pipe orifice grinding device and pipe machining device

The invention discloses a pipe orifice grinding device, and relates to the field of pipe production and processing. The device comprises a rack, and the rack is used for fixing and supporting the grinding device, a fixed workbench and a movable workbench are arranged on the rack, and the fixed workbench and the movable workbench are each provided with a grinding mechanism; the device further comprises a guiding mechanism, and the guiding mechanism is arranged between the fixed workbench and the movable workbench and used for feeding, discharging, grinding and unloading. Grinding is performed through cooperation of the guiding mechanism and the grinding mechanisms, burrs at the end of the pipe orifice are removed, manual handheld electric or pneumatic grinding machines are replaced for grinding, the efficiency is ten times that of manual grinding, and therefore the problem that in the prior art, the grinding efficiency is low is solved. 本发明公开了种管口打磨装置，涉及管子生产加工领域。本发明包括机架，所述机架用于固定和支撑所述打磨设备，机架上设置有固定工作台和移动工作台，固定工作台
