10. A working method of a surface treatment apparatus for stainless steel pipes for construction, comprising the surface treatment apparatus for stainless steel pipes for construction according to any one of claims 1 to 9, the working method comprising the steps of:

firstly, adjusting the distance between limiting baffles (14) according to the length of the stainless steel pipe to be processed, and sequentially placing the stainless steel pipe to be processed on a blanking support plate (11);

driving a linear electric cylinder (25) to enable an electric cylinder sliding block (252) to drive an arc-shaped plate (26) to be far away from a first motor (21), releasing a stainless steel pipe (16) in a blanking mechanism (1) to fall into a limiting groove (241), sequentially rotating a rotating roller (23) for 90 degrees twice, enabling three stainless steel pipes (16) to be arranged in the limiting groove (241), and driving the linear electric cylinder (25) to enable the arc-shaped plate (26) to move towards the first motor (21) until the arc-shaped plate (26) completely penetrates through an arc-shaped through groove (221);

thirdly, driving a first motor (21), rotating a roller (23) and the three stainless steel pipes (16) to rotate, polishing and derusting the stainless steel pipes (16) and the frosted inner walls of the arc-shaped plates (26), moving the arc-shaped plates (26) away from the first motor (21) after polishing is finished, and rotating the rotating roller (23) to enable the three stainless steel pipes (16) to fall down in sequence;

after the four stainless steel tubes and the three stainless steel tubes (16) fall on the workbench (30), the third pneumatic cylinder (55) is driven, the blocking plate (56) blocks the stainless steel tube (16) at the bottom, then the second pneumatic cylinder (52) is driven, and the upper pressure plate (53) and the side baffle (54) limit the three stainless steel tubes (16);

and fifthly, driving a first pneumatic cylinder (41), driving a polishing wheel (44) to move inwards by a second motor (43) until a limiting column (45) enters the inner wall of the stainless steel pipe (16), enabling the side wall of the polishing wheel (44) to be attached to the end part of the stainless steel pipe (16), then rotating a handle (352), enabling an abutting plate (351) to be in contact with the polishing wheel (44), increasing balance force, driving the second motor (43), enabling the polishing wheel (44) to rotate to polish the end part of the stainless steel pipe (16), and after polishing is completed, driving a second pneumatic cylinder (52) and a third pneumatic cylinder (55) to enable the stainless steel pipe after surface treatment to fall down to a material receiving bottom plate (63) so as to facilitate collection.
