Horizontal lathe with automatic cleaning device

The invention discloses a horizontal lathe with an automatic cleaning device, and relates to the technical field of machining. The device comprises an upper opening cabinet, a limiting assembly on the upper surface of the upper opening cabinet comprises a concentric-square-shaped frame, a first hydraulic cylinder and a second motor, a transverse plate is arranged on the upper surface of the concentric-square-shaped frame, a rectangular through groove is formed in one side of the upper surface of the transverse plate, a cleaning assembly is arranged on the rear surface of the upper opening cabinet, and the cleaning assembly comprises a water pump and an L-shaped frame. By arranging the limiting assembly, the transverse plate and the cleaning assembly, the limiting assembly is used for limiting the position of the hollow pipe and does not shield the outer surface of the hollow pipe, then the lathe can comprehensively machine the outer surface of the hollow pipe conveniently, chippings generated in the machining
