Description
Technical field
The utility model belongs to the technical field of instrument of grinding, polishing or sharpening, is specifically related to a kind of diamond-resin grinding wheel.
Background technology
Whole hard alloy V-CUT cutter is because of the accurate fresh-cut processing of feature is now the widely used in pcb board of printed circuit board industry such as its hardness is high, machining accuracy is high and wearability is strong.V-CUT cutter tooth portion shape mostly is V-shaped grooved, makes with superhard material hard alloy powder metallurgical, and its processing generally forms with resin diamond grinding wheel grinding.
The bowl-type resin diamond grinding wheel shape of processing V-shaped groove and structure are as shown in Figure 1, grinding wheel base body 1 ' adopts aluminium alloy to make, grinding part 2 ' is made up of resin and diamond particles, and resin and diamond particles stir and be pressed into entirety with grinding wheel base body in mold cavity, and hot setting is shaping.Bowl-type resin diamond grinding wheel can because wedge angle wearing and tearing in grinding process, surface passivation and often need to carry out reconditioning shaping to emery wheel angle.Emery wheel reparation generally employing corundum wheel and resin diamond grinding wheel is repaired the method for grinding.
Existing bowl-type angle emery wheel front end face ratio is easier to reconditioning, rear side angle faces because of with alloy matrix aluminum face and more difficult reconditioning, for prevent alloy matrix aluminum again reconditioning time blocking corundum wheel, need before reconditioning to carry out the empty cutter spacing 3 ' of turnery processing to the rear side angle of resin diamond grinding wheel.The clearance position processing of aluminium alloy grinding wheel base body, because being an inclined-plane, engine lathe needs the operating personnel of certain technology just can process, and reconditioning difficulty is comparatively large, brings puzzlement like this to emery wheel reparation.
V-CUT cutter tooth portion grooved grinding process is because of groove depth requirement, and also there are certain requirements resin diamond grinding wheel radial depth, requirement can not be less than groove depth.Like this from existing structure resin diamond grinding wheel section, new emery wheel is from using through reconditioning for several times until the radial depth of resin-diamond part is less than the V-shaped groove depth of work pieces process, an effective usable floor area of resin diamond grinding wheel only has 1/3rd of resin-diamond cross section, what its excess-three was divided two cannot use not because radial depth, and therefore the availability of the skive of existing structure is low.
Above-mentioned discussion content object be to reader introduce may to below by the various aspects of technology relevant for the various aspects of the present utility model be described and/or advocate, believe that this discussion content contributes to for reader with background's information, to be conducive to understanding various aspects of the present utility model better, therefore, should be appreciated that it is discuss to read these with this angle, instead of admit prior art.
Utility model content
The purpose of this utility model is avoid deficiency of the prior art and provide a kind of diamond-resin grinding wheel, and its availability is higher, and reconditioning difficulty is less.
The purpose of this utility model is realized by following technical scheme:
A kind of diamond-resin grinding wheel is provided, the grinding part comprise grinding wheel base body, being formed by diamond particles and resin, described grinding wheel base body entirety is bowl-type, described grinding part entirety is annular, the axial cross section of grinding part is trapezoidal, the inner peripheral surface of described grinding part is fixedly connected with the outer peripheral face of described grinding wheel base body, grinding part axial cross section form trapezoidal bottom and be positioned at grinding wheel base body indent side.
Wherein, the outer peripheral face of described grinding wheel base body is provided with some fixing annular grooves, the inner circumferential of described grinding part is provided with the raised line be embedded in fixing annular groove.
Wherein, described grinding wheel base body evagination side is being provided with empty avoiding portion near periphery.
Wherein, the end face of described grinding wheel base body indent side is being provided with empty avoiding step near periphery.
Wherein, described grinding wheel base body is that aluminium alloy is made.
Owing to have employed above-mentioned structure, the structure of the utility model to existing bowl-type resin diamond grinding wheel is improved, and has following beneficial effect:
1, the axial vane surface contact structures between grinding part and grinding wheel base body are improved to radial ringed contact structures, and such grinding wheel die easily makes, and the flaring cup wheel that one set of die can be applicable to multi-angle uses;
2, grinding wheel base body evagination side is being provided with empty avoiding portion near periphery, and the convenient like this reparation to grinding part angle faces, reduces reconditioning difficulty;
3, the end face outermost of grinding wheel base body indent side is concordant with grinding part, and is provided with empty avoiding ledge structure, like this under the bond strength ensureing grinding wheel base body and grinding part, can reduce the front turnery processing amount to grinding wheel base body of reconditioning;
4, from the reconditioning cross section of grinding part, the utilization rate of grinding part significantly improves, generally, emery wheel to reconditioning can not be repaired, grinding part remaining part only has 1/3rd, and effective use part can reach 2/3rds.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings.
Fig. 1 is the structural representation of the diamond-resin grinding wheel of correlation technique.
Fig. 2 is the structural representation of diamond-resin grinding wheel of the present utility model.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, it should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 2, diamond-resin grinding wheel described in the utility model, comprises grinding wheel base body 1 and grinding part 2.Described grinding wheel base body 1 is made for aluminium alloy, and entirety is bowl-type, and described grinding part 2 is made up of diamond particles and resin, and entirety is annular.When diamond-resin grinding wheel makes, resin and diamond particles stir and be pressed into entirety with grinding wheel base body, final high temperature curing molding in mold cavities.The axial cross section of described grinding part 2 is trapezoidal, and the inner peripheral surface of described grinding part 2 is fixedly connected with the outer peripheral face of described grinding wheel base body 1, grinding part 2 axial cross section form trapezoidal bottom and be positioned at grinding wheel base body 1 indent side.Owing to being radial ringed contact structures between grinding part and grinding wheel base body, such grinding wheel die easily makes, and the flaring cup wheel that one set of die can be applicable to multi-angle uses.Further, as can be seen from the figure, from the reconditioning cross section of grinding part, the utilization rate of grinding part significantly improves, generally, emery wheel to reconditioning can not be repaired, grinding part remaining part only has 1/3rd, and effective use part can reach 2/3rds.
