Floating boring tool structure for inner wall of steel tube

Abstract

The invention provides a floating boring tool structure for the inner wall of a steel tube. The floating boring tool structure comprises a tool bar, a first tool groove and a second tool groove. The first tool groove is formed inside the portion above the tool bar, and the first tool groove and the tool bar are of an integrated structure. The second tool groove is formed inside the portion below the tool bar, and the second tool groove and the tool bar are of an integrated structure. Springs are mounted inside the first tool groove and the second tool groove and connected with the first tool groove and the second tool groove in a penetrating manner through half-shaft bolts correspondingly. Tool aprons are mounted inside the first tool groove and the second tool groove and connected with the first tool groove and the second tool groove in a penetrating manner through half-shaft bolts correspondingly. The floating boring tool structure is structurally improved, therefore, the structure has the advantages that tools are not likely to be broken, the structure is convenient to dismount when being replaced for repair, the rough machining and finish machining integrated operation functionis achieved, and machining precision and machining efficiency are improved; and thus, problems in the background art are effective solved, and defects in the background art are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of boring cutters, in particular to a floating boring cutter structure for processing the inner wall of a steel pipe. Background technique [0002] In the mechanical processing of steel pipe products, it is often necessary to derust or expand the inner wall of the steel pipe so that it can meet the requirements of the use. This processing process needs to be completed with the help of a boring machine, so the boring tool used to process the inner wall of the steel pipe on the boring machine plays a very important role. [0003] However, because the inner wall of the steel pipe is relatively rough or there is a certain beating range of the steel pipe during processing, the ordinary fixed boring tool is prone to breakout or the machining accuracy of the inner wall of the steel pipe is poor, and the existing floating boring tool also has structural design problems. It is too complicated, which leads to more tr...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a floating boring tool structure on the inner wall of a steel pipe to solve the problems in the above-mentioned background technology that due to the relatively rough inner wall of the steel tube or a certain jumping range of the steel tube during processing, ordinary fixed boring tools are prone to breakouts. Or the machining accuracy of the inner wall of the steel pipe is poor, and the existing floating boring tool also has too complicated structural design, which leads to troublesome disassembly during maintenance and replacement, and problems and deficiencies such as the inability to improve machining accuracy and machining efficiency.
