Burr clearing device used for inner wall of steel pipe

Abstract

The invention discloses a burr clearing device used for the inner wall of a steel pipe. The burr clearing device comprises a movable shaft and a connecting body. The movable shaft and the connecting body communicate with each other to form a water injection channel. The front section of the movable shaft is sleeved with a scrubbing brush, and the tail section of the movable shaft is sleeved with annular check rings. The middle section of the movable shaft is sleeved with an annular tool apron. Blades are annularly distributed on the outer wall of the annular tool apron. An arc-shaped groove is formed in the inner wall of the annular tool apron. The middle section of the movable shaft is fixedly connected with a bar-shaped protrusion. An arc-shaped rod is arranged in the arc-shaped groove. The bar-shaped protrusion can slide in the arc-shaped groove in the direction of the arc-shaped rod. An installing hole is formed in the inner annular face of the bar-shaped protrusion. The bottom of the installing hole is fixedly connected with a guide post and an elastic supporting part. A stopping piece with the front end face fixedly connected with a sliding part is further arranged. The arc-shaped rod is provided with a plurality of fixing holes capable of being matched with the sliding part. According to the burr clearing device, the sliding part can be placed into the fixing holes under the supporting action of the elastic supporting part so that the position between the annular tool apron and the movable shaft can be fixed; and the slipping phenomenon between the annular tool apron and the movable shaft is avoided, and cutting force of the blades is weakened.

Description

technical field [0001] The invention relates to auxiliary equipment for an argon arc welding machine, in particular to a burr cleaning device for the inner wall of a steel pipe. Background technique [0002] When the steel pipe is welded, a certain amount of burrs will be generated inside and outside the steel pipe near the weld seam, which will reduce the flow rate of the fluid in the pipe when the steel pipe is in use, and the protrusions at the weld seam will be easily corroded, which will lead to a decrease in the overall strength of the weld seam, reducing the The service life of the steel pipe is shortened; the traditional internal burr removal equipment mainly focuses on the removal of solder residue and protrusions around the weld seam and the weld seam, but the solder residue and protrusions scattered to other parts of the inner wall of the steel pipe during welding are not cleaned thoroughly. . Contents of the invention [0003] The object of the present inventi...
