Abstract
The invention discloses a centerless grinder and a method for grinding workpieces by using the same. The centerless grinder comprises a grinding wheel, a guide wheel controlling the rotation of the workpiece, a support frame for supporting the workpiece, a cooling liquid supply tube for supplying cooling liquid, and a high-pressure water pipe for supplying high-pressure liquid; the grinding wheel comprises a wheel grinding surface for grinding the workpiece; the high-pressure water pipe is adjacent to the wheel grinding surface of the grinding wheel; and the outlet direction of the high-pressure water pipe faces to the wheel grinding surface. The wheel grinding surface can be ensured to be rough through spraying the high-pressure liquid to the wheel grinding surface of the grinding wheel to wash scraps generated by grinding and attached to the wheel grinding surface of the grinding wheel in a grinding process. Therefore, the work efficiency of the grinder is improved, and the grinding time is saved.
Description
Technical field
The present invention relates to the centreless grinding field, particularly relate to the method for a kind of centerless lapping machine and use centerless lapping machine grinding work-piece.
Background technology
Centreless grinding is a kind of to the method for polishing surface fast and accurately that is difficult to the fixing accessory.Accessory to be ground (being workpiece) directly down receives rigid support and need not this accessory is exerted pressure in cutting, and this allows to carry out more greatly or darker cutting and make grinding accessory microscler, frangible or easy deformation become possibility.In accessory, many other parts that can process straight shape and wedge shape bearing, cylinder, the body of rod, needle roller, axle bush, screw, fastener, piston, piston ring, gun barrel, bar, axle, shell, tappet, pen accessory, hypodermic syringe needle, forging and process by the centreless grinding producer by various metals, plastics, pottery and composite.
The difference that centreless grinding and other type are ground is: workpiece is not suspended between the center or is connected to workpiece end or surface by other anchor clamps.Workpiece places on blade or the bracing frame, and guide wheel (the most often being processed by elastomeric material) contact workpiece impels it near bracing frame and near emery wheel.In the most general system, the emery wheel rotation also makes the workpiece rotation, and the cutting pressure that produces by emery wheel forces workpiece near regulating wheel and bracing frame, and regulating wheel control workpiece rotary speed.Therefore, emery wheel and workpiece can the different revolutions of per minute (rpms) rotations.Yet in the emery wheel rotary course, emery wheel grinds workpiece, after grinding a period of time, has on the wheel flour milling of emery wheel and grinds the talus accumulation that produces, and causes the smooth relatively of original coarse abradant surface change.When emery wheel continues to grind to workpiece, because the smooth meeting of ratio that abradant surface becomes diminishes the cutting force when grinding, thereby cause grinding efficiency to reduce, milling time increases.
Summary of the invention
The technical problem that the present invention mainly solves provides the method for a kind of centerless lapping machine and use centerless lapping machine grinding work-piece, can improve the efficient of centreless grinding, reduces milling time.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of centerless lapping machine is provided; Comprise: the guide wheel of emery wheel, control workpiece rotation, the bracing frame of supporting workpiece, the cooling fluid supply pipe of cooling fluid is provided and the high-pressure water pipe of highly pressurised liquid is provided; Said emery wheel comprises the wheel flour milling that is used for grinding work-piece, the wheel flour milling of the contiguous said emery wheel of said high-pressure water pipe, and the water outlet direction of said high-pressure water pipe is towards the said flour milling of taking turns.
In preferred embodiment of the present invention, said high-pressure water pipe is arranged on the support frame as described above.
In preferred embodiment of the present invention, the highly pressurised liquid of said high-pressure water pipe ejection is a water.
For solving the problems of the technologies described above, another technical scheme that the present invention adopts is: a kind of method of using the centerless lapping machine grinding work-piece is provided, comprises: use bracing frame to support workpiece to be ground; Use the disc sharpener of emery wheel to grind in the face of supported workpiece; Use cooling fluid that polished workpiece is cooled off; Use the highly pressurised liquid flushing attached to grinding the chip that produces on the wheel flour milling of emery wheel.
The invention has the beneficial effects as follows: utilization of the present invention is inject high pressure liquid on the wheel flour milling of centerless lapping machine, and the method that the wheel flour milling is washed away improves the degree of roughness of abradant surface, thereby improves grinding efficiency, reduces milling time.
Description of drawings
Fig. 1 is the structural representation that adopts centerless lapping machine of the present invention;
The mark of each parts is following in the accompanying drawing: emery wheel 1, workpiece 2, guide wheel 3, bracing frame 4, cooling fluid supply pipe 5, high-pressure water pipe 6, wheel flour milling 11.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the present invention provides a kind of centerless lapping machine, and this centerless lapping machine comprises an emery wheel 1, one guide wheel 3, one bracing frames 4, one cooling fluid supply pipes 5, and a high-pressure water pipe 6.Said emery wheel 1 comprises that taking turns flour milling 11 is used for grinding work-piece 2; Said guide wheel 3 is used to control the rotation of workpiece 2, and support frame as described above 4 is used for supporting workpiece 2, and said cooling fluid supply pipe 5 is used to provide cooling fluid; Temperature is too high when avoiding grinding, and said high-pressure water pipe 6 is used to provide highly pressurised liquid.Bracing frame 4 between emery wheel 1 and guide wheel 3, a workpiece 2 can place be used on the bracing frame 4 processed.
To introduce the course of work of said centerless lapping machine below.When centerless lapping machine was started working, guide wheel 3 began rotation with emery wheel 1, and workpiece 2 places on the bracing frame 4 and rotated by drive, and is ground by emery wheel 1.Cooling fluid supply pipe 5 ejection cooling fluids, cooling fluid is sprayed onto on the workpiece 2, thereby guarantees that workpiece 2 temperature can be not too high.High-pressure water pipe 6 is to the wheel flour milling 11 ejection highly pressurised liquids of emery wheel 1, because the powerful percussion of highly pressurised liquid is washed away owing to grinding the chip that depends on wheel flour milling 11 that produces on the wheel flour milling 11, it is comparatively coarse that wheel flour milling 11 can become.Like this wheel flour milling 11 bigger cutting force (it is sharper promptly to take turns flour milling 11) just can be provided, thereby the grinding rate of emery wheel 1 will improve, milling time shortens, grinding efficiency is improved.
In another embodiment, the highly pressurised liquid of high-pressure water pipe 6 ejections is a water.Highly pressurised liquid continuously is ejected on the wheel flour milling 11, makes wheel flour milling 11 keep coarse.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
