A tool system for turning and milling the inner hole of large-diameter pipe

Abstract

The invention discloses a cutter system for processing large-diameter pipe inner holes through turning and milling. The cuter system comprises an upper support sheet, a lower support sheet, a push block, a disc spring, an upper support frame, a lower support frame, a sleeve, a milling cutter, a cutter bar and friction plates, wherein the upper support frame is an cube in shape, the lower support frame is a hollow cylinder, the upper support frame is connected with the lower support frame, the upper support sheet is arranged on the upper end of the upper support frame, the disc spring is arranged in the lower support frame, one end of the disc spring is fixed in the lower support frame, the other end of the disc spring is connected with the push block, the lower support sheet is arranged on the push block, the sleeve is arranged in the upper support frame, the cutter bar is arranged in the sleeve, and one end of the cutter bar penetrates the upper support frame and is connected with the cutter. By adopting the cutter system disclosed by the invention, the axial deformation and vibration of the cutter bar during deep hole processing can be reduced effectively, the noise generated from cutting vibration can be abated, the processing precision can be improved, and the service life of the cutter can be prolonged.

Description

technical field [0001] The invention relates to the field of tool system structure, in particular to a tool system for turning and milling the inner hole of a large-diameter tube. Background technique [0002] At present, a boring tool is mainly used to process the inner hole of a large-diameter pipe through a boring process. This method is difficult to break chips during the machining process, the tool wears quickly, and the machining efficiency is low. [0003] It is a new technology to use turning and milling to cut the inner hole of large-diameter pipes. It has good chip shape, low tool wear and high efficiency, but there is no matching tool system yet. Contents of the invention [0004] In order to solve the above problems, the present invention provides a tool system for turning and milling the inner hole of a large-diameter tube. [0005] In order to achieve the above object, the technical scheme that the present invention takes is: [0006] A tool system for turn...
