Description
Technical field
The utility model relates to grinding tool technical field, has related to a kind of emery wheel for grinding knife tool.
Background technology
Emery wheel of the prior art normally adds bonding agent in abrasive material, has the circular grinding wheel of through hole through pressed compact, center dry and that roasting forms.Emery wheel in use, tends to occur wearing and tearing, the emery wheel that wearing and tearing just need to more renew while acquiring a certain degree.Because this emery wheel only depends on the body of emery wheel in the process of grinding, dispel the heat, while causing wheel grinding, dispel the heat slower, cause abrasion of grinding wheel fast, the cycle of changing emery wheel is shortened.
The working face of emery wheel of the prior art only has one, when the cutters such as processing lathe tool, milling cutter, for cutter head being processed as to default angle, need to progressively process or progressively process by a plurality of variform emery wheels by repeatedly changing the angle of the working face of cutter and emery wheel, could on the cutter head of cutter, process default angle, during visible emery wheel process tool of the prior art, exist production process too much to cause the defect that productivity ratio is low.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of emery wheel, its object: carry out two procedures and just can complete the processing of cutter, rapid heat dissipation during grinding, has improved the production efficiency of cutter.
For achieving the above object, the technical solution of the utility model is as follows:
An emery wheel, comprises matrix, the first grind section and the second grind section, the first grind section be shaped as annular, one side side of matrix is radiating surface, the opposite side side of matrix is joint face, and the radiating surface of matrix is provided with fin, and the side of fin is arc surface;
The second grind section is arranged on the joint face of matrix, and the first grind section is socketed in the sidepiece of the second grind section;
The middle part of matrix is provided with the first circular axis hole, and the middle part of the second grind section is provided with and corresponding the second circular axis hole of the first circular axis hole, and the outer circumference of the second circular axis hole is provided with at least two equally distributed rectangle keyways;
The abradant surface of the first grind section is arc surface, and the working face of the second grind section is the step surface of two stepwises, and the first terrace of step surface and the transition portion between the second terrace are arc surface, and the corner on step surface is circular arc.
Preferably, the quantity of described rectangle keyway is four.
By technique scheme, the radiating surface of matrix is provided with fin, has increased the contact area of this emery wheel and air; The side of fin is arc surface, and when fin rotates, fin rotation promotes air and forms whirlpool, has promoted radiating rate, has guaranteed that this emery wheel has good heat dispersion when grinding; This emery wheel can carry out preliminary processing to cutter by the first grind section, then the second grind section can carry out final processing to cutter, carries out two procedures and just can complete the processing of cutter, has improved the production efficiency of cutter; The outer circumference of the second circular axis hole is provided with at least two equally distributed rectangle keyways, by rectangle keyway, has prevented becoming flexible and coming off between this emery wheel and installation shaft.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, the specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of emery wheel, comprise matrix 1, the first grind section 2 and the second grind section 3, the first grind section 2 be shaped as annular, one side side of matrix 1 is radiating surface, the opposite side side of matrix 1 is joint face, and the radiating surface of matrix 1 is provided with fin 11, has increased the contact area of this emery wheel and air; The side of described fin 11 is arc surface, and when fin rotates, fin rotation promotes air and forms whirlpool, has promoted radiating rate, has guaranteed that this emery wheel has good heat dispersion when grinding.
The second grind section 3 is arranged on the joint face of matrix 1, and the first grind section 2 is socketed in the sidepiece of the second grind section 3, makes this emery wheel be fixed into a firmly integral body.
The middle part of matrix 1 is provided with the first circular axis hole 12, the middle part of the second grind section 3 is provided with and corresponding the second circular axis hole 31 of the first circular axis hole 12, the outer circumference of the second circular axis hole 31 is provided with four equally distributed rectangle keyways 32, by rectangle keyway 32, has prevented becoming flexible and coming off between this emery wheel and installation shaft.
The abradant surface of the first grind section 2 is arc surface, the working face of the second grind section 3 is the step surface of two stepwises, the first terrace and the transition portion between the second terrace of step surface are arc surface, corner on step surface is circular arc, this emery wheel can carry out preliminary processing by 2 pairs of cutters of the first grind section, the second grind section 3 can be carried out final processing to cutter again, carries out two procedures and just can complete the processing of cutter, has improved the production efficiency of cutter.
Be exactly more than a kind of design feature and action effect of emery wheel, its advantage: simple in structure, this emery wheel can firmly be connected with installation shaft; Heat dispersion is good, and process tool production efficiency is high.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
