Technical field
The utility model relates to a kind of vitrified abrasive, particularly a kind of double-layer ceramic emery wheel of surface band groove.
Background technology
Along with the progress of material technology, laminar composite obtains development, and some mechanical workpieces can exist that the material composition of different parts is different, hardness is different, surface roughness is not equal.When carrying out Precision Machining to this type of workpiece, if adopt gradation processing, then there is inefficient shortcoming; Also be difficult to ensure to add machining accuracy and the uniformity of tool setting etc. in man-hour simultaneously.And when fine finishining is carried out to some workpiece with dual-cavity, also there is above problem, particularly under high-speed and high-efficiency high-precision grinding condition.Therefore, seek the thick accurate grinding of the cylindrical of highly-efficient processing unlike material workpiece, inner circle or plane, highly-efficient processing has the workpiece of multiple groove, is current urgent problem.Chinese patent literature CN201264220Y discloses a kind of combinated grinding wheel structure of improvement on July 1st, 2009, comprises parallel grinding wheel body.Rough grinding wheel layer and finishing wheel layer, described rough grinding wheel layer and described finishing wheel layer are arranged on the outer peripheral face of described parallel grinding wheel body successively along emery wheel direction of feed, it is characterized in that: it also comprises half finishing wheel layer, described half finishing wheel layer is arranged between described rough grinding wheel layer and described finishing wheel layer.This grinding wheel structure is made up of three layers of emery wheel, carry out respectively roughly grinding, partly refining and fine grinding, due to three layers of emery wheel compact siro spinning technology each other, add man-hour, part bits material cannot be discharged, stay surface of the work, affect crudy, in addition, carry out roughly grinding, partly refining and fine grinding simultaneously, workpiece surface temperature raises, and affects workpiece.Therefore, be necessary to make further improvements.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, double-layer ceramic emery wheel of making easily, can adapting to the surface band groove of different materials and different shape requirement.It is mainly used in the thick accurate grinding of the cylindrical of unlike material workpiece, inner circle or plane, be particularly useful for the disposable corase grind and the fine grinding that machine workpiece, and be processed with the workpiece of multiple groove simultaneously, low to overcome the working (machining) efficiency existed in prior art, be comparatively difficult to ensure card machining accuracy and the conforming weak point of tool setting.
The double-layer ceramic emery wheel of a kind of surface band groove designed by this object, comprises matrix and the emery wheel layer being arranged at matrix surface; It is characterized in that: emery wheel layer is made up of removable first emery wheel and the second emery wheel, the emery wheel that user can be high to different abrasive concentration, granularity, hardness, ring width and ring as required carries out replacing and regulates; Be provided with annular groove between first emery wheel and the second emery wheel, be conducive to chip removal and cooling down.
The vitrified abrasive of this structure can successively be roughly ground and fine grinding workpiece, and concrete structure is as follows, and the first emery wheel is rough grinding wheel, and the second emery wheel is finishing wheel; First emery wheel external diameter is equal with the second emery wheel external diameter; Add man-hour, workpiece first contacts the first emery wheel, then contacts the second emery wheel.Because rough grinding wheel and finishing wheel are fixed on same vitrified abrasive jointly, first workpiece contacts the first emery wheel and carries out corase grind processing, and the part processed contacts the second emery wheel immediately and carries out fine grinding, effectively improves working (machining) efficiency and product quality.
In addition, the vitrified abrasive of this structure can be processed with the workpiece of multiple groove simultaneously, because first and second emery wheel is replaceable adjustment, the width-adjustable joint of groove matches with processing work, the degree of depth matches according to processing request and processing work or departs from processing work, and the first emery wheel and the second emery wheel external diameter size match with processing work respectively.This processing not only effectively improves working (machining) efficiency and product quality, also add controllability, has good adaptive capacity.
First emery wheel and the second emery wheel all replaceable become the high emery wheel of different abrasive concentration, granularity, hardness, ring width or ring, and be fixed on matrix with bonding or screw connection manner respectively, replacing for convenience detach; Described matrix is metal alloy compositions.
Ceramic emery wheel of the present utility model arranges double-deck removable emery wheel, leaves groove between emery wheel.When double-deck emery wheel is respectively rough grinding wheel and finishing wheel, corase grind processing and fine grinding can be carried out to processing work simultaneously, effectively improve working (machining) efficiency and product quality.When needing the workpiece being processed with multiple groove, according to factors such as groove location, width, the degree of depth and processing requests, correspondence being carried out to double-deck emery wheel and changes, with satisfied processing needs.It has feature that is simple and reasonable, that make easily, can adapt to different materials and different shape requirement.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
First embodiment
See Fig. 1-Fig. 2, the double-layer ceramic emery wheel of this surface band groove, comprise matrix 1 and the emery wheel layer being arranged at matrix 1 surface, emery wheel layer is made up of removable first emery wheel 2 and the second emery wheel 3, user can change the emery wheel of different performance as required, with satisfied processing needs; Be provided with annular groove 1.1 between first emery wheel 2 and the second emery wheel 3, be conducive to chip removal and cooling down.
The vitrified abrasive of this structure can successively be roughly ground and fine grinding workpiece, and concrete structure is as follows: the first emery wheel 2 is rough grinding wheel, and diamond grit is 45#, and the second emery wheel 3 is finishing wheel, and diamond grit is 120#; First emery wheel 2 external diameter is equal with the second emery wheel 3 external diameter, is 203.2mm; The width of the first emery wheel 2 is greater than the second emery wheel 3, is respectively 16mm and 6.5mm; The thickness of the first emery wheel 2 and the second emery wheel 3 is 5.1mm; Groove 1.1 width is 3mm, and the degree of depth is 15mm.During making, first sinter out the first emery wheel 2 and the second emery wheel 3 that required fixed outer diameter, ring width and ring are high; Then, the first emery wheel 2 and the second emery wheel 3 are bonded and fixed on the matrix 1 processed by design drawing, can making be completed.
See Fig. 3, add man-hour, emery wheel rotates, under two emery wheel rings are all in running order, processing work 4 moves from left to right along a direction, because rough grinding wheel and finishing wheel are fixed on same vitrified abrasive jointly, first workpiece contacts the first emery wheel 2 and carries out corase grind processing, the part processed contacts the second emery wheel 3 immediately and carries out fine grinding, groove be provided with chip removal and cooling down effect, be corase grind with fine grinding between transition zone.This structure effectively improves working (machining) efficiency and product quality.
Specifically, the first emery wheel 2 and the second emery wheel 3 all replaceable become the high emery wheel of different abrasive concentration, granularity, hardness, ring width or ring, and be fixed on matrix with bonding or screw connection manner respectively, replacing for convenience detach; Matrix 1 is metal alloy compositions.
Second embodiment
