Description
Technical field
The utility model relates to a kind of dedicated tool of roll forming emery wheel.
Background technology
Forming grinding wheel grinding is utilized to be a kind of method that grinding-shaping cutter is conventional, be applied to abrasive wheel and carry out the processing request that tool sharpening can complete many complicated faces, in prior art, forming grinding wheel generally adopts the diamond manual trim method of forming, this reconditioning mode be by operator with its operating experience to carry out the finishing of emery wheel, the method measures after first repairing again, if curved surface to be trimmed is excessive there will be the phenomenon that cannot make up, too smallly continue reconditioning if repaired again and can cause time waste, and this time reconditioning and next time reconditioning is impossible completely the same, thus cause the problem of uniformity difference.Forming grinding wheel repairs the frequency greatly in process, and therefore working (machining) efficiency is low, and one batch of homogeneity of product difference is the fatal defects that prior art exists.The present invention is exactly be a kind of molding cutter of forming grinding wheel finishing design.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, a kind of dedicated tool of roll forming emery wheel is provided, this cutter can ensure the uniformity that abrasive wheel forming is repaired, accurately can complete abrasive wheel forming finishing, repair without the need to repeated measurement, and the packing of emery wheel can be improved, extend the service life of emery wheel.
In order to solve the problems of the technologies described above, the utility model comprises mandrel, described mandrel is provided with the rolling tool of pre-molding, described rolling tool is interval with multiple elastic gap groove.
The middle part of described mandrel is provided with annular chuck.
The middle part of described rolling tool is provided with the positioning through hole coordinated with mandrel.
Described rolling tool is sleeved on mandrel and one end coordinates with chuck, and an end of described mandrel is bolted with locking nut.
Between described rolling tool and locking nut, packing ring is installed.
The two edges of described rolling tool outer circumference surface are the arc-shaped curved surface of pre-molding, and described elastic gap groove extends internally from the outer circumference surface of rolling tool.
The length of described elastic gap groove is 1/1 to three/4th of rolling tool radius.
Adopt the dedicated tool of the roll forming emery wheel of such scheme compared with prior art to have the following advantages: rolling tool pre-molding, its shape and grinding wheel shape adapt, and are convenient to the finishing of forming grinding wheel; Rolling tool is fixed on mandrel, and carry out abrasive wheel forming finishing by rolling process, the uniformity of repairing can be ensured like this, and accurately can complete abrasive wheel forming finishing, repair without the need to repeated measurement, additionally improves the packing of emery wheel and the service life of emery wheel, and then improve the working (machining) efficiency of product; Rolling tool is provided with the elastic gap groove that spacing does not wait, and elastic gap groove extends internally from the arc-shaped curved surface of rolling tool, the sand grains that when can hold roll extrusion in elastic gap groove, emery wheel drops.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of mandrel;
Fig. 3 is the structural representation of rolling tool;
Fig. 4 be in Fig. 3 A-A to sectional view.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, the dedicated tool of this roll forming emery wheel comprises mandrel 1, mandrel 1 is provided with the rolling tool 2 of pre-molding, rolling tool 2 after shaping in the present embodiment adapts with the shape needed for forming grinding wheel, rolling tool 2 is interval with multiple elastic gap groove 22, distance between elastic gap groove 22 is unequal, with reference to accompanying drawing 4, the two edges of rolling tool 2 outer circumference surface are the arc-shaped curved surface of pre-molding, namely the two edges of rolling tool 2 outer circumference surface are the arc-shaped curved surface that rounded corners is formed, this arc-shaped curved surface and the shape needed for forming grinding wheel adapt.Elastic gap groove 22 extends internally from the outer circumference surface of rolling tool 2, and the sand grains that when can hold roll extrusion in elastic gap groove 22, emery wheel drops, the length of the present embodiment Elastic clearance groove 22 is 1/1 to three/4th of rolling tool 2 radius.The middle part of mandrel 1 is provided with annular chuck 11, the middle part of rolling tool 2 is provided with the positioning through hole 21 coordinated with mandrel 2, rolling tool 2 is sleeved on mandrel 1 and one end coordinates with chuck 11, one end of mandrel 1 is bolted with locking nut 12, packing ring 3 is installed between rolling tool 2 and locking nut 12, namely the other end of rolling tool 2 coordinates with packing ring 3, and rolling tool 2 can be fixed on mandrel 1 by adjustment locking nut 12, thus realizes the location of rolling tool 2.
Add man-hour, the rolling tool 2 of pre-molding to be fixed on mandrel 1 clamping after on mandrel 1 on lathe, again rolling tool 2 being leaned against on emery wheel and to give certain radial pressure, by continuously repeating above-mentioned action, finally completing the shaping finishing of forming grinding wheel.
The roll extrusion mode adopted in the application is applied to a kind of processing method of metal surface usually, firmly do as annular knurl, surperficial coldization, the roll extrusion of emery wheel is the compressibility of space and the emery wheel utilizing emery wheel inside to exist, utilize rolling tool that emery wheel is deformed, thus obtain the outer contour shape needed.So just make the packing of emery wheel improve, and the service life of emery wheel can also be extended, and then improve the working (machining) efficiency of product.
The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, replace all in protection domain of the present utility model based on the equivalent variations of concrete structure on the utility model and parts.
