Description
Technical field
The present invention relates to a kind of inside pipe wall grinding-polishing device, belong to technical field of metallurgical equipment.
Background technology
Along with the continuous progress of industrial manufacturing technology is more and more higher to pipe fitting inner wall quality requirement, require that the defect such as retention, crackle, sand holes to longer circular materials in the tube inwall exists is carried out reconditioning or carries out Dimension correction.In the past to major diameter comparatively short tube material inner wall defect usually adopt artificial hand-held grinder to carry out reconditioning or polishing, its operating efficiency is low.To the inner wall defect reconditioning of minor diameter compared with long pipe fittings, usual employing elongate rod is installed an emery wheel and is carried out reconditioning or polishing to the inwall of pipe fitting, owing to being difficult to control to the thrust of inside pipe wall during emery wheel (or polishing wheel) grinding, and drive longer the making of axle of emery wheel easily to shake during emery wheel (or polishing wheel) grinding, affect grinding or quality of finish.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of inside pipe wall grinding-polishing device, it not only increases the operating efficiency of grinding or polishing, and effectively can control the thrust to inside pipe wall, ensure that final grinding or quality of finish.
The object of the present invention is achieved like this: a kind of inside pipe wall grinding-polishing device, it comprises draw bar, described draw bar front end is provided with centering support, the second adjustable wheel that frame peripheral is evenly provided with three adjustable radial expansion distances is propped up in described centering, described centering support is provided with bearer carrier, described bearer carrier front end is hinged with rocking bracket, described rocking bracket front end edge horizontal direction is provided with power part, described power part output is provided with emery wheel, vertically be provided with in the middle part of described rocking bracket and hold out against parts, the described element outputs that holds out against is provided with the first adjustable wheel, described rocking bracket rear end is fixedly installed rocking bracket pivot angle stop, described rocking bracket pivot angle stop is positioned at below rocking bracket and bearer carrier pin joint.
Described draw bar adopts the tubular rod segments of boring.
Described second adjustable wheel is fixed by holding screw and centering support.
Described power part adopts motor or hydraulic motor.
The described parts that hold out against adopt cylinder or oil cylinder.
Described rocking bracket pivot angle stop is made up of adjustment screw and locking nut.
The installed position of described rocking bracket pivot angle stop is provided with alarm.
Compared with prior art, the present invention has following beneficial effect:
A kind of inside pipe wall grinding-polishing of the present invention device, it not only increases the operating efficiency of grinding or polishing, and effectively can control the thrust to inside pipe wall, ensure that final grinding or quality of finish.
