Abstract
The invention relates to a mirror surface rolling tool with internal cooling lubricating function. A position of the rolling tool close to a clamping position is provided with an oil-taking device; the interior of the rolling tool is provided with a flow passage connected with the oil-taking device; an oil outlet of the internal flow passage is arranged on the surface of a mandrel of the rolling tool; the diametrical connection between the oil-taking device and the rolling tool is movably sealing connection so that the oil-taking device does not rotate with the rolling tool. When in work, the rolling tool does rotary movement or workpieces do rotatory movement and the workpieces are still or the rolling tool is still; a lubricating oil or cooling fluid oil delivery pipe is connected with the oil-taking device of the tool; the lubricating oil or cooling fluid reaches the top of a rolling needle of the rolling tool by the internal flow passage and the oil outlet, outflows from the periphery of the rolling needle, and then contacts the surface of the workpieces, thus achieving the effects of lubrication and cooling; the lubricating oil or cooling fluid can also dash out impurities to achieve the purpose of washing. The mirror surface rolling tool can be used on equipments such as lathes, drill presses, milling machines, machining centers and the like, and is widely applied to mechanical workout industries.
Description
Technical field
The present invention relates to not have the cold conditions field of machining of machining metal parts.Particularly the metal parts Surface Machining can be gone out (Ra≤0.1 μ m) mirror surface accuracy and have the mirror surface rolling tool with internal cooling lubricating function of internal cooling lubricating function.
Background technology
At present, the rolling tools that can process mirror surface accuracy are in reality processing, all be to water or spreading upon on rolling tools and the workpiece from the outside with lubricating oil or cooling fluid with instrument with oil pump or operating personnel on the equipment in the process, in the actual processing, when rolling tools contact with workpiece, formed a hermetically-sealed construction, oil or cooling fluid are can't enter into machined surface to cool off in real time, lubricate; And when instrument or workpiece rotate,, thereby make oil or cooling fluid lose lubricated and cooling effect because action of centrifugal force can make oil or cooling fluid splash out.Lubricated, cooling is untimely, the life-span of rolling tools and processed workpiece accuracy also are subjected to very big infringement.Have to increase the flow of oil or cooling fluid through repeatedly smearing or strengthen oil pump power, so just can cause many inconvenience to production, oil or cooling fluid can be covered actual working position, make operating personnel can't see intuitively that workpiece to be machined working position morpheme changes, and influencing the lifting of processing quality, production efficiency, the use amount of oil or cooling fluid also is multiplied; Simultaneously, during the cleaning maintenance of rolling tools, must dismantle instrument, even disassemble the purpose that just can reach inner cleaning.Through document retrieval, also there is not a kind of mirror surface rolling tool at present with internal cooling lubricating function.
Summary of the invention
The object of the invention is exactly for the cooling that solves existing rolling tools, lubricated and cleaning shortcoming, and a kind of mirror surface rolling tool with internal cooling lubricating function is provided.At parts list and during mirror finish, lubricating oil or cooling fluid are from the outside jet flow in the inside of rolling tools, and under the instrument centrifugal action of rotation, just can enter into machined surface in real time than low discharge lubricating oil or cooling fluid, rolling tools, processed parts are lubricated completely from inside to outside, cool off and clean.
Core technology of the present invention is provided with runner in rolling tools inside exactly, and lubricating oil or cooling fluid are outwards flowed internally, and is lubricated, cooling effect is obvious; During the rolling tools maintenance, just need not dismantle and to clean automatically.The technical scheme that adopts is: the sliding mirror surface rolling tool of interior cooling profit function, by oil-feed device, the shank that can be connected with lathe or install, size adjustment mechanism, needle roller maintainance set, can be at the needle roller or the roller of limited range activity, and mandrel is formed, be provided with an inner flow passage in rolling tools inside, it is direct or indirect connections with the inner flow passage of rolling tools that there are oil-feed device or pipeline in the outside; Inner flow passage comprises shank inner flow passage, mandrel inner flow passage and oil-out, and the oil-out of inner flow passage is arranged on the mandrel surface, and shank inner flow passage, mandrel inner flow passage are communicated with the oil-out of mandrel head; Shank, size adjustment mechanism, needle roller maintainance set, needle roller, mandrel can rotate together; Mandrel can contact with needle roller or roller are movable, and the parts that can provide support for needle roller or roller; Mandrel has the conical surface, lubricating oil or cooling fluid enter inner flow passage from the oil-in of oil-feed device, the conical surface along mandrel directly contacts with needle roller, needle roller and workpiece to be machined are played real-time cooling effect and lubrication, simultaneously residue on the needle roller and impurity are developed in the slit between needle roller maintainance set and the needle roller, and workpiece is cleaned, lubricates and cooling.
When the present invention works, rolling tools rotate or workpiece rotates, static or rolling tools of workpiece or rolling tool are static, lubricating oil or cooling fluid fuel feed pump are connected with the oil-feed device of instrument, lubricating oil or cooling fluid arrive the needle roller top of rolling tools by inner flow passage, flow out around needle roller, the contact workpiece surface reaches effect lubricated, cooling again.In the course of the work, lubricating oil or cooling fluid can also be gone out impurity, reach the purpose of cleaning.
Advantage of the present invention and beneficial effect are:
1, interior lubrication system is simple and easy, makes, assembles, uses, safeguards very convenient.
2, lubricating oil or cooling fluid can enter into machined surface in real time by inner flow passage, and effect lubricated, cooling is obvious, the service life of favourable raising rolling tools.
3, lubricating oil or cooling fluid under external pressure fuel pump and the effect of instrument rotary centrifugal force, can be gone out the trace impurity that produces in the processing internally, reach and clean rolling tools and workpiece purpose.
4, lubricating oil or cooling fluid outwards flow internally by inner flow passage, and the purpose that less lubricating oil or coolant rate just can lubricate, cool off, clean has reduced the use amount of lubricating oil or cooling.
