Abstract

The invention discloses a large-diameter spiral welded aluminum alloy pipe inner weld seam and inner wall grinding device and a method thereof. The device comprises an aluminum alloy pipe, a pressingmechanism, a feed guiding bar, a power wheel bracket, an unpowered wheel bracket, an aluminum alloy pipe support base, a front supporting seat, a guiding rod feeding base, a feeding seat, a sanding head, a compliant device, an impeller, an ejecting wheel device, a pressing wheel, and an encoder, wherein the aluminum alloy pipe supporting base is connected to the ground through an expansion screw and used for storing the power wheel bracket, the unpowered wheel bracket and the like and an aluminum alloy pipe; the aluminum alloy pipe is placed on the power wheel bracket and the unpowered wheel bracket, is supported by a roller wheel, and is pressed by a certain pressing force provided by the pressing mechanism; the guiding rod feeding base is connected to the ground through an expansion screw for placing the feed guiding rod, the front supporting seat and a feeding seat device; the impeller, the compliant mechanism and the sanding head are sequentially fixed at the end portion of the feed guiding rod; and a guiding power unit is driven by a motor.

Description

technical field [0001] The invention relates to the field of forming welding of metal pipes, in particular to a device and method for grinding the inner weld seam and the inner wall of an ultra-long, large-diameter spiral welded aluminum alloy pipe. Background technique [0002] Large-diameter aluminum alloy pipe is a metal pipe with an outer diameter greater than 600mm. It is mainly used in aerospace, energy and electric power fields. Part - the demand for large-diameter aluminum alloy pipes is increasing, and spiral-welded large-diameter aluminum alloy pipes have been mass-produced. [0003] In the application, there are certain requirements for the roughness of the inner wall of the aluminum alloy tube, so it needs to be polished to meet the surface roughness requirements. The large-diameter aluminum alloy tube weld seam grinding and the inner wall of the aluminum alloy tube for spiral welding process are polished, and the manual grinding workload is large. , low efficie...
