Description

TECHNICAL FIELD

[0001] The utility model relates to machining technical field, especially pipe wall hole deburring device. BACKGROUND

[0002] When the pipe material forms the inner hole through cutting, drilling, punching and other processing modes, burrs often appear on the hole wall edge, and the pipe wall hole deburring device can accurately position these burrs and remove them. In the pipe inner wall deburring link, a scraper is used as a tool to perform operation. When the scraper is placed inside the pipe, the rotation mode is immediately started. The burrs attached to the inner wall are in close contact with the blade. By virtue of the strong cutting force generated by the high-speed rotation of the scraper, the protruding burrs are gradually flattened and polished, so that the inner wall of the pipe is restored to a smooth and flat state. In the pipe processing, due to the diversity of pipe specifications, the size is different. This puts forward the requirement of fine adaptation for the polishing work of the pipe inner wall. Since the inner diameter and outer diameter of each pipe are different, in order to achieve the best polishing effect, the scraper that accurately matches the size of the current pipe must be replaced. It takes time to replace the scraper that matches the size of the pipe each time. This frequent replacement operation will lead to a decrease in overall production efficiency. SUMMARY
