Description
Technical field
The utility model relates to a kind of burnishing device, relates in particular to a kind of polishing device for inner wall that is used for health grade stainless steel pipe.
Background technology
Now stainless steel welded pipe being carried out the inwall polishing is a kind of common process means.Existing internally polisher group will comprise that a guide rail, places the power set on the guide rail and is erected at clamp on the guide rail.Power set have one and cooperate the rotating shaft of welded tube rotation and be positioned at the distolateral burnishing surface of rotating shaft, the rotating shaft cross-under is in welded tube when driving power device carries over guide rail and advances, in rotation, utilize burnishing surface grinding and polishing inner wall of welded pipe, to obtain the comparatively wall of light.But this equipment is because burnishing surface is to grind inner wall of welded pipe with rotating shaft with the direction of rotation at a high speed, therefore from microcosmic, this burnishing surface can be at inner wall of welded pipe, directly form sleek along week, but, when fluid is flowed through welded tube vertically just with direction of flow be vertical to sleek, the resistance when just forming the fluid channelling, rate of flow of fluid is slowed down, and then reduce utilization benefit.Also have patent document to disclose a kind of polishing machine: Chinese patent " pipe internally polisher (CN2633508Y) ", include a frame, a transmission device and a burnishing device, this frame can be up horizontal for several adapters.This transmission device has the driven pulley of a hub setting at the frame other end, and one can drive driving wheel, the hub setting driven pulley at the frame other end, and a servo motor that can drive driving wheel.This burnishing device have one pass take over cutting not and the affixed cable wire and of driving wheel, driven pulley be fixed on the polishing shuttle in cable wire centre position.When driving wheel drive cable wire moves, make and polish shuttle straightaway in adapter.Though this structure makes sleek and flow direction equidirectional.But for the stainless steel of health level, the requirement of inwall is very high, and sleek obviously will be flowed through the fluid retention of stainless steel inwall easily in sleek, thereby influence the requirement of health level.The structure of the polishing machine that discloses in the above-mentioned patent document is very complicated simultaneously, utilize the driving wheel driven pulley to drive cable wire, under high-speed case, the quite severity of shake, so the service life that also can damage equipment with regard to obvious decline to the grinding-polishing effect of inwall, the device for positioning and securing of Jie Guaning is a lot of simultaneously, change buff spindle and take over all inconveniences of ten minutes, influence operating efficiency, the tubing of different size need use the polishing shuttle of different size, has improved production cost.Polishing shuttle does not simultaneously have fixture, because the too small stock removal that causes of pressure is too little, efficient is low when moving in taking over.
Summary of the invention
The utility model provides a kind of can realize polishing fast, and the inner wall smooth of the stainless steel tube after the polishing does not have lines, can the stainless steel tube of different size be polished, and satisfies the internally polisher of the stainless steel tube of health level requirement; It is bad to have solved the stainless steel polishing effect that exists in the prior art, the technical problem of versatility difference.
The utility model also provides a kind of technology simple simultaneously, high efficiency, and good stability is changed the polishing body internally polisher of stainless steel tube easily; Solved the complex process that exists in the prior art to polishing in the stainless steel tube, because the little efficient of the little stock removal of machined surface pressure is low, the technical problem of poor stability.
Above-mentioned technical problem of the present utility model solves by following technical proposals: a kind of internally polisher of stainless steel tube, comprise frame and polishing mechanism, and be provided with the clamping rotating mechanism of stainless steel tube and the bracing frame of stainless steel tube in the end of frame; Described polishing mechanism comprises that the axial actuating mechanism of polishing body, polishing body and polishing body press down positioner, described polishing body is positioned at stainless steel tube, be provided with the axial actuating mechanism of polishing body at the two ends of frame, on frame, be provided with stainless steel tube bracing frame and polishing body and press down positioner.Stainless steel tube is fixed by the clamping rotating mechanism of frame end and is rotated, polishing body in stainless steel tube is driven along the stainless steel tube axially-movable by the axial actuating mechanism at its two ends simultaneously, inwall to stainless steel tube carries out grinding-polishing, polishing body is parallel with stainless steel tube, polishing body only is exactly a back and forth movement vertically back and forth in stainless steel, need not drive shuttling movement by belt or all the other devices, improved the stability of whole device, can not make that burnishing device trembles, and influences the polishing effect of burnishing surface.Polishing body below stainless steel tube presses down positioner polishing body is applied a downward power, makes polishing body be adjacent to stainless steel inside pipe wall all the time, like this machined surface is had individual pressure, the big efficient height of stock removal.Simultaneously since polishing body be to be positioned at stainless steel tube and only be axially-movable and have hold-down devices that polishing body is pressed on it on stainless steel inside pipe wall, therefore can process the stainless steel tube of different size, only polishing body need be inserted in the stainless steel tube just passable.
The bracing frame of stainless steel tube can be that support roller also can be to support cambered surface, the two ends that can be arranged on frame also can be provided with a plurality of, as preferably, being provided with several on described frame is parallel to each other and uniform stainless steel tube bracing frame, described stainless steel tube bracing frame comprises two support columns that are parallel to each other, one end of support column is fixed on the frame, and the other end is equipped with roller.The good frictional force of support roller support effect is little, makes things convenient for the rotation of stainless steel tube.A plurality of bracing frames make and make things convenient for grinding-polishing by the stressed even of stainless steel tube.
