Denoiser for milling tubes

Abstract

The invention provides a denoiser for milling tubes. The denoiser comprises a noise reduction plug mechanism, a plug core mechanism and a turn button mechanism, wherein the noise reduction plug mechanism is provided with an expansion tube 21, an expansion block 1 and an expansion slit 6 are arranged on the expansion tube, conical internal threads 2 are arranged in the expansion block, an annular passage 14 is formed in the upper part of the outer wall of the expansion block, an annular spring 15 is arranged in the annular passage, silicon rubber coating 17 is arranged on the outer wall of the annular passage, a plug core snap spring 12 is arranged in the expansion tube, the plug core mechanism is provided with a plug core 3, conical external threads 4 for the expansion tube are arranged on the outer wall of the plug core, a turncap 5 is arranged at the upper end of the plug core, and an inner turn hole 19 is formed in the turncap; the turn button mechanism is provided with a falling key 9; the silicon rubber coating arranged on the outer wall of the noise reduction plug is in contact with the inner wall of a tube to increase a friction combination surface, so as to facilitate the quick screwing and locating of the denoiser for milling tubes; since the falling key arranged on the plug core is adopted, the denoiser for milling tubes is convenient to fetch, and the denoiser can be quickly and quantitatively screwed by using a torque wrench to prevent the tube from generating a tuning-fork effect to produce noise, so that the noise reduction effect is improved.

Description

technical field [0001] The invention relates to an outer wall processing tool for several milling tube openings, in particular to a noise reducer for milling tubes. Background technique [0002] When using digital milling to process the outer wall and nozzle of pipe fittings, in order to improve production efficiency, pay by quantity is used to increase the feed speed of the rough knife, but the noise generated by the tuning fork effect not only pollutes the environment and affects other people's work, but also Affect the health of employees and damage machine tools. Contents of the invention [0003] In view of the above problems, the present invention provides a noise reducer for pipe milling, which is easy to use and reduces noise. [0004] According to the technical solution of the present invention: a noise reducer for pipe milling, including a noise reduction plug mechanism, a plug core mechanism, and a knob mechanism. [0005] The noise reduction plug mechanism is...
