Automatic inner wall polishing machine of drum barrel

Abstract

The invention relates to an automatic inner wall polishing machine of a drum barrel, which comprises a base, a polishing roller and a drive roller, wherein the drive roller comprises a bottom supporting roller mounted on the working table top of the base axially and horizontally, two side rollers and an upper pressing roller mounted on a machine frame at the upper part of the base, a circular workpiece clamping site is formed among the bottom supporting roller, the two side rollers and the upper pressing roller, the working table top thereon is horizontally and movably provided with a moving seat on which a rotating shaft axially parallel to the bottom supporting roller is arranged horizontally and rotationally, the end of the rotating shaft is fixedly provided with the polishing roller, and the moving seat drives the polishing roller to horizontally reciprocate parallel to the upper surface of the bottom supporting roller. The invention has compact structure, and scientific and reasonable deign, is capable of completing the polishing work of the inner wall of the drum barrel highly efficiently, quickly and stably, has the outstanding advantages of high degree of automation, simple operation, stable run, high precision and the like, and is an automatic inner wall polishing machine of the drum barrel with relatively high innovation.

Description

technical field [0001] The invention belongs to the field of drum musical instrument processing devices, in particular to an automatic drum inner wall polishing machine. Background technique [0002] In the drum musical instrument processing process, after the drum is made into a cylindrical shape from a raw material plate, the outer wall and the inner wall of the drum need to be polished. As a high-quality drum instrument, the inner wall of the drum still needs to reach a certain degree of smoothness to ensure the sound quality and timbre of the finished drum instrument. The existing drum inner wall polishing machine has a relatively simple structure, which is mainly composed of a machine base platform and a drum driving roller and a grinding roller installed vertically on the surface of the horizontal worktable on the upper part of the machine base. , the drum wall is pressed between the driving roller and the grinding roller, and the grinding roller realizes the grinding...

AI Technical Summary

Problems solved by technology

The main problem existing in the existing drum inner wall grinder is: the drum needs to be manually supported during the grinding process, and the drum wall is kept tightly pressed between the driving roller and the grinding roller, which not only increases the labor intensity of the operator , and cause uneven pressing force, which affects the grinding effect; in addition, the existing drum inner wall grinder still has the disadvantages of low degree of automation and low processing efficiency.
