Description

Corase grind grinding dish
Technical field
The present invention relates to a kind of corase grind grinding dish.
Background technology
From a kind of thicker all side grinding dishes relatively of document CH-PS 434 023 cicada, this week side grinding dish comprises a plurality of with fabric single-deck that strengthen, that be bonded to each other on whole, wherein can be provided with cushions in adhesive phase.This assembly type grinding dish has better grinding power than the compact grinding dish that single-piece makes up.In addition, from document CH-PS 434 023 a kind of compact grinding of cicada dish also, this compact grinding dish is arranged in outside zone diametrically at it and always has no abrasive material area, this no abrasive material area is formed by the intermediate layer of annular, this intermediate layer can be removed if necessary once more, thereby forms tangible gap between adjacent areas.These no abrasive material areas have caused cold especially grinding and have produced other chip pocket in addition during all sides are carried out grinding, described chip pocket can cause the grinding power of remarkable rising in addition all identical dish is formed.
From document EP 1 543 923 A1 a kind of corase grind grinding of cicada dish, the diameter of this corase grind grinding dish is than at least 9 times greatly of its thickness.This corase grind grinding dish be used in hand-held, on pneumatic actuation or the electrically driven (operated) angle milling drum.At this, strong vibration has appearred in grinding is used, and this vibration can cause very big physical damnification to hand-arm-system of user.In order to reduce this vibration, between each layer, externally all be furnished with annular separate layer in the working region.Described separate layer is of compact construction in this working region.Described separate layer mainly has the function that reduces vibration amplitude during grinding.
Summary of the invention
The objective of the invention is, realize a kind of be used for that hand-held uses, by the corase grind grinding dish of vibration damping, this corase grind grinding dish has simple especially structure and so can be manufactured especially simply.
According to the present invention, this purpose realizes by the feature of claim 1.
Feasible this part dish of preproduction very simply of the structure of the part dish that each is flat.Because described part dish is flat, so be unlike in the danger that has distortion in the crooked grinding dish like that, thereby described part dish can closely recline veritably as far as possible mutually, in other words can recline mutually in the mode of almost not having air gap in that do not connect that is not bonding operate outside zone.
Flat structure and the hub portion installation in this corase grind grinding dish of corase grind grinding dish makes to be particularly conducive in described hub portion internal thread is set, and becomes possibility on the external screw thread by the feasible output shaft that is screwed in hand-guided grinding of this internal thread.This causes: although described structure is flat, the nut that does not need to protrude in described corase grind grinding dish is with on the output shaft that is fixed on milling drum, thereby realized that also the present invention roughly grinds the plane of grinding dish or the use of almost plane.This structure of hub portion also can be used in the flat grinding dish with structure of the present invention certainly.
Can draw favourable form of implementation by dependent claims.
Description of drawings
From below in conjunction with accompanying drawing to drawing other features of the present invention, advantage and details the description that embodiment did.Wherein
Fig. 1 is illustrated in grinding and has a hand-guided grinding according to corase grind grinding dish of the present invention in using,
Fig. 2 illustrates the perspective view according to corase grind grinding dish of the present invention,
Fig. 3 illustrates the exploded view of corase grind grinding dish according to the present invention before assembling,
Fig. 4 illustrates the side view according to the part dish of corase grind grinding dish of the present invention, and
Fig. 5 illustrates the side view that the present invention on the output shaft that is installed in hand-guided grinding roughly grinds the grinding dish.
The specific embodiment
As showing ground by Fig. 1 and Fig. 5, corase grind grinding dish 1 is used in hand-guided grinding 2, is on the so-called angle milling drum.Grinding dish 1 has central opening 3 for this reason, and hub portion 4 is housed in central opening 3.Hub portion 4 has internal thread 5, grinding dish 1 can be screwed on the output shaft that is provided with external screw thread 67 of milling drum 2 by this internal thread.
That grinding dish 1 comprises in its basic structure is a plurality of, i.e. 2 to 10 part dishes 8 thin, that have outer diameter D.Each part dish 8 respectively has a girth member 9,10 on two outside, wherein be furnished with the abrasive particle 11 with binding agent (being generally phenolic resins) bonding between described two girth members 9,10.Girth member 9,10 comprises the fabric of crossing with the binder-impregnated of abrasive particle 11 (being generally glass fabric).These part dishes 8 are hardened.In other words these part dishes 8 do not have covered (unkaschiert) not having label or ply of paper etc. on its outside that is on the surface in the exposure of girth member 9,10.
In order to make corase grind grinding dish 1, the part dish 8 of a plurality of level lands design is piled up in stacked mode up and down, wherein in the annular region of central opening 3, always be coated with adhesive phase 12, be generally thermosetting resin/thermosetting plastics.It is thin as to make and will be pressed into by the group that a plurality of part dishes 8 are formed when roughly grinding grinding dish 1 to have the adhesive phase 12 of diameter d, and adhesive is accommodated in the part of surface irregularity of the part dish 8 that reclines mutually.This result who causes is, part dish 8 is mutually permanently connected in the zone of the adhesive phase 12 with diameter d, though and part dish 8 be not close to mutually in the outside of corresponding adhesive phase 12 and interconnect." being close to " in this article the meaning mutually, not to be expressed as that adjacent grinding dish 1 has at this accurately be 0 spacing, do not have the air gap that material impact is arranged between two adjacent parts dishes 8 but be illustrated in concerning practice.Therefore for the thickness a of the grinding dish of forming by the individual part dish 8 of n 1, satisfy: a ≈ n * b with thickness b.The thickness b of part dish 8 satisfies: 0.8mm≤b≤1.4mm.Ratio for the outer diameter D of the diameter d of adhesive phase 12 and grinding dish 1 satisfies: 0.2≤d/D≤0.65.Outer diameter D satisfies: 10mm≤D≤300mm.Wherein adjacent part dish 8 mutually discrete zones have formed the working region 13 of grinding dish 1.
Hub portion 4 only slightly with the edge 14 that is crimped on the side, promptly deviating from the central opening 3 that passes grinding dish 1 on the side of milling drum 2, be designed to thereby though corase grind grinding dish 1 is not crooked flat fully, can be obliquely as corase grind grinding dish 1---in other words use to start mode described and shown in Figure 1.But also can carry out flat surface grinding, the end face 15 that corase grind grinding dish 1 sets mutually by itself and the edge 14 of hub portion in flat surface grinding uses on workpiece 16 in the mode plane or almost plane.If corase grind grinding dish 1 is used obliquely corresponding to the accompanying drawing among Fig. 1, then this is taking place under situation of α between vertical line 18 on the surface to be ground 19 of the output shaft 7 of the axis 17 of grinding dish 1 and then milling drum 2 and workpiece 16 at angle.Angle [alpha] satisfies: 20 °≤α≤60 °.And if carry out grinding with the mode plane earth of having mentioned, then angle [alpha] satisfies: 0 ° of α ≈.
