Description
(1) technical field:
The present invention relates to grinding tool, be specially a kind of high-efficient cutting emery wheel.
(2) background technology:
Adopt emery wheel to accomplish to the grinding of metal or nonmetallic materials, use the emery wheel of grinding face as plane (or running orbit is the plane) for plane processing, then often adopting grinding face for special-shaped edging processing is the formed grinding wheel of abnormity.Emery wheel can produce a large amount of grinding heats and break flour in working angles; Therefore in emery wheel processing (flat surface grinding and special-shaped grinding) time, need cool off, and the type of cooling is that the cooling body of emery wheel machining tool provides cooling water, and cooling water acts on grinding face; Cooling water cools off grinding face on the one hand; Another important function is that a large amount of break flours is washed away eliminating, and the rate of discharge of break flour and discharge rate will directly affect crudy and efficient.
According to the difference of the type of cooling, existing emery wheel machining tool is divided into external-cooling type grinding machine and inner-cooled grinding machine.
1, the cooling body of external-cooling type grinding machine simple (emery wheel of adapted is a plain wheel); It mainly is the cooling tube of a connection pumping source; Cooling tube is installed on the work top; The cooling fluid of cooling tube ejection directly acts on the emery wheel working position, because the centrifugal action that emery wheel rotates, cooling fluid will fly away from the emery wheel working position fast.And combine during grinding tightr between working face and the work piece; The break flour that grinding produces has formed the sealing to cooling water; In fact cooling fluid is difficult to enter into the working face of processing, and just plays the effect of cooling after precooling before the emery wheel work, the emery wheel work; From the chip removal angle, cooling fluid can only wash away the outer break flour of processing working face, and has little scope for one's talents for the break flour that is enclosed within the machining area.
2, the use of inner-cooled grinding machine is in order to improve the refrigerating function of external-cooling type grinding machine; The inner-cooled grinding machine wants supporting use to have the emery wheel of interior cooling structure; The structure of this inner-cooled emery wheel is the water inlet that on the axis hole of grinding wheel base body central shaft position, offers with the contraposition of inner-cooled grinder wheel rotating shaft delivery port; The inside of grinding wheel base body also offers water stream channels few in number (routine is that 120 °, 90 °, 60 °, 45 °, 30 ° five equilibriums are uniformly distributed with 3,4,6,8,12); And offer the delivery port of respective amount on the bull ring of emery wheel; Cooling fluid is supplied with through the emery wheel rotating shaft delivery port that emery wheel is installed, and cooling fluid gets into the water inlet of grinding wheel base body axis hole from the delivery port of emery wheel rotating shaft, through water stream channel from the bull ring the delivery port ejection and act on the grinding working face; From the chip removal angle, the limited and water jet quantity of the water yield of delivery port ejection very little, strength is not enough, can't get rid of the break flour that is enclosed within machining area equally.
In sum, adopt existing inner-cooled grinding machine, the break flour that the supercooling liquid of coming round directly washes away in the cutting zone maybe not; The eliminating of break flour still relies on the rotation of emery wheel self and takes out of, and the thread that emery wheel self is taken break flour out of is big, and rate of discharge and drag-out are limited; A large amount of break flours are concentrated and are stored between the emery wheel abrasive particle of cutting zone; Get ability the quarter that has weakened the emery wheel abrasive particle, directly affects crudy and efficient, and this is the key point that the emery wheel operating efficiency can't improve.From the position of cooling water effect, as if the cooling effect of said external-cooling type grinding machine should be more effective than external-cooling type grinding machine, but in fact really not so: because the delivery port on the emery wheel bull ring is few in number; Can not guarantee in the emery wheel process, contact with work piece in the scope of line length, all have cooling water to act on the grinding face at emery wheel; Under the extreme case,, even there is not delivery port to appear on the grinding face in some period of grinding; Therefore its inner-cooled effect is discontinuous even dry grinding; Be not omnidistance interior cooling truly, its cooling effect and external-cooling type weak effect are few, even not as good as the external-cooling type effect.Owing to will solve layout and emery wheel rotating shaft and the emery wheel axis hole entery and delivery port UNICOM and the sealing problem of inner cooling line; It is the reason that causes inner-cooled grinding machine mechanism complicated; And then urge the manufacturing cost that has risen the inner-cooled grinding machine; And plain wheel can't use on the inner-cooled grinding machine, must use the emery wheel with cooling structure of special facture, causes final comprehensive process cost to increase.
In addition; For special-shaped edging processing; The special-shaped flour milling shape of emery wheel is corresponding to the corner shape need of material, and the conventional edge angular shape of final molding is an arc, and other shapes except that arc are also arranged; As be the geometry of rule, or non-well-behaved geometry for constituting by line segments such as straight line, camber line, curves.
For the stock of special-shaped edging, should be reserved with allowance, and allowance is not to stay to the shape of special-shaped grinding face, initial how much states of allowance are (common for square) of rule relatively in most cases, material also is uniform.In process; Possibly there is inequality in the processing capacity at each position that emery wheel abnormity flour milling is in axial direction gone up; The relation of some or even difference of magnification, and the material of emery wheel is inhomogeneity, degree of wear is different with the difference of processing capacity with regard to each position of having caused emery wheel abnormity flour milling for these; Make the special-shaped flour milling of emery wheel very easily lose shape and can't normally use, need often to repair or lose shape and scrap.
(3) summary of the invention:
To the weak point of prior art, the objective of the invention is to design a kind of high-efficient cutting emery wheel quick, high-speed cutting of realizing.
Can realize the high-efficient cutting emery wheel of above-mentioned purpose; Comprise matrix and be located at the bull ring on the matrix, offer the delivery port that connects bull ring on the flour milling of said bull ring, said each delivery port is communicated with the water stream channel that correspondence is offered in the matrix; Said each water stream channel meets at water inlet; In the arc length scope that different is sets arbitrarily on said flour milling, be provided with at least greater than 0 delivery port, the arc length of said any setting is that 1 times～3 times bull rings contact line length during with the work piece grinding.
The delivery port that the present invention is provided with; The break flour that produces in the time of can be in time with grinding in cooling emery wheel and work piece is included in the delivery port and is stored; The delivery port that stores break flour forwards the grinding working face to when outer with emery wheel, because centrifugal force and flow action (cooling water can spray from delivery port through the water stream channel corresponding to delivery port from the entering of the water inlet on the matrix); Break flour in the delivery port can be discharged smoothly, thereby timely and effectively break flour is got rid of.
For high-quality emery wheel; As be used for requirement on machining accuracy height, the demanding workpiece of flatness, and preferably in 1 times of grinding contact line length scope, have greater than 0 appearance bits mouth or delivery port, just in grinding contact line length scope, have the fraction even the minimum part of a delivery port at least; Can guarantee each moment in the emery wheel process like this; Contact with work piece in the scope of line length at emery wheel, all have cooling water to act on cooling in time on the grinding face, realize whole process cooling truly; Guarantee that emery wheel can not cause inordinate wear because of local temperature is too high; The break flour that produces when this delivery port can also in time make grinding in addition can get into rapidly in the delivery port and store, and timely and effectively break flour is got rid of, thereby is got ability the quarter of guaranteeing the emery wheel abrasive particle.Yes from improving cooling and chip removal effect, and delivery port is The more the better, but after taking all factors into consideration factor such as processing cost, can specifically set according to condition of different.
Like being provided with under the big and sparse situation at little (the being contact wire length) delivery port of grinding scope; No matter delivery port quantity in 1 times of grinding contact line length scope is the major part of a delivery port, or the fraction of a delivery port even minimum part can obtain excellent effect; Under the situation that small and dense collection is set of delivery port; Appearance bits mouthful quantity in 1 times of grinding contact line length scope is delivery port or more than, like several delivery ports or tens, tens delivery ports, according to long-term grinding experience and experiment preferably then; Delivery port at most generally is no more than 30 for well; Too much, increase the difficulty of making, reduced the intensity of bull ring.
For more inferior emery wheel, as be used for the workpiece that requirement on machining accuracy is not high, flatness is less demanding, perhaps the low speed emery wheel; Then delivery port offers density and can reduce a little; According to the requirement of different quality emery wheels, delivery port is provided with condition and can suitably relaxes, through experiment repeatedly; 3 times and 3 times with interior grinding contact line length scope in; Have greater than 0 delivery port, just can play the cooling and the chip removal effect that are clearly better than prior art products performance, delivery port at most generally is no more than 30 for well equally.
Because the present invention is provided with abundant delivery port, also effectively reduce grinding hoop material in addition, reduced the emery wheel cost.
Flour milling for said bull ring is the situation of special-shaped flour milling; Said delivery port is " the non-physical treatment district " that does not participate in grinding on the special-shaped flour milling; Special-shaped flour milling residue position except that " non-physical treatment district " is then for participating in " the physical treatment district " of grinding; Said " physical treatment district " in disalignment to the allowance of the total line length of locational circumference corresponding to the work piece co-located; Its corresponding relation is proportional relationship or approximate proportional relationship, thereby the shape of waiting that forms special-shaped flour milling is worn and torn structure.
It is the physical treatment district (part of contact work piece when referring to grinding) in the said bull ring; The processing capacity that to accomplish at the process needs according to emery wheel distributes the total line length of circumference of correspondent entity processing district, the i.e. big position of workpiece allowance at grinding wheel spindle on diverse location; Its corresponding physical treatment district total line length of circumference is then big; The position that workpiece allowance is little, its corresponding physical treatment district total line length of circumference is then little, constitutes direct proportion or approximate proportional relationship between the two; Thereby the shape of waiting that forms emery wheel is worn and torn structure, solves or alleviates special-shaped emery wheel with this and lose the shape problem.
When work piece to shape need is not very high, wider range; According to the processing capacity of emery wheel in the completion of process needs; On diverse location, distribute the total line length of circumference of correspondent entity processing district at grinding wheel spindle, the proportionate relationship that constitutes between the two can suitably be relaxed.
Said delivery port (being non-physical treatment district) can be set to Any shape in principle, as being set to the geometry of rule, or is made as the non-well-behaved geometry that is made up of line segments such as straight line, camber line, curves.For the arc machined surface of work piece, the shape of said delivery port (being non-physical treatment district) can adopt be easy to process circular or oval.
The axial width of delivery port (being non-physical treatment district) greater than work piece machined surface thickness situation under; Physical treatment district formation has grinding of microspur discontinuous or half discontinuous grinding structure; Half discontinuous grinding structure has littler beating, and more helps the higher processing that the limit requires of collapsing.
Under the situation of axial width less than work piece machined surface thickness of delivery port (being non-physical treatment district), the physical treatment district constitutes continous way grinding structure, eliminates the limit that collapses of beating and bringing, and can satisfy to collapse the high processing operating mode of limit requirement.
Emery wheel of the present invention all can use on external-cooling type grinding machine and inner-cooled grinding machine: use in the inner-cooled grinding machine, said water inlet is opened on the axis hole of central shaft position, place, matrix axle center; Use in the external-cooling type grinding machine, said water inlet is opened on the matrix, and the water inlet on the said matrix is external uncovered, behind the emery wheel installation in position, and uncovered water spray position facing to external-cooling type grinding machine cooling tube.
Processing and manufacturing for ease of water inlet and water stream channel; Need further to optimize basal body structure, said a kind of optimizing structure comprises two substrates, and said bull ring clamping is consolidated between the substrate; Also formed the storage area of water stream channel effect between the said substrate, water inlet is opened on the substrate.
Further can substrate wherein be made as the pressing plate of installing with another piece substrate, said central shaft position is located on another piece substrate, is communicated with external-cooling type grinding machine cooling tube for making things convenient for water inlet, and said water inlet is the collar extension that is opened on the said pressing plate.
Said collar extension can form naturally, and way is to be ring flat-plate with platen design, and the interior ring diameter of ring flat-plate is greater than the central shaft position of substrate, and collar extension is formed between the central shaft position of interior ring and substrate of pressing plate.
For the situation of two emery wheels or the coaxial use arranged side by side of a plurality of emery wheels, particularly, can take mode with the water stream channel mutual conduction between the emery wheel to the emery wheel that is used for the external-cooling type grinding machine, guarantee the supply of cooling fluid to each emery wheel.
Technical scheme of the present invention also is fit to " dry grinding " processing, but the dry grinding cooling water of this moment is " air ", and said water inlet, water stream channel and delivery port promptly hold the bits mouth and then correspond to air inlet, gas channel and gas outlet.
Advantage of the present invention:
