Description
Technical field
The utility model relates to the super-hard abrasive tool for hole processing.
Background technology
At present, the processing of a lot of occasions hole part can utilize grinding tool to carry out, because grinding process can produce a large amount of heats and grindstone dust, in order to guarantee the service life of crudy and grinding tool, just need to adopt cooling fluid to lower the temperature, and need in time grindstone dust to be discharged.Application number is 200420108518.9, Granted publication number discloses the super-hard abrasive tool of a kind of processing metal hole part for the Chinese patent of CN 2744467Y, comprise matrix and the bistrique that is installed in matrix fore-end, if the front end face of matrix is exposed to bistrique outside, can on matrix, process run through base shaft to matrix cooling passage; If bistrique wraps up the front end face of matrix, position that can be corresponding with matrix front end face in bistrique arranges cooling fluid container cavity, and the intake chute that runs through vertically bistrique is set on bistrique outer peripheral face, this intake chute bottom communicates with cooling fluid container cavity, and cooling fluid can be discharged.But, the grinding tool of rear a kind of bistrique form is generally used for the ropy workpiece of processing bore area, the impulsive force that in process, bistrique is subject to is larger, and above-mentioned intake chute is not only difficult to processing, and can weaken the structural strength of bistrique, and in order in the bistrique position corresponding with matrix front end face, cooling fluid container cavity to be set, just need to lengthen the axial dimension of bistrique, can weaken equally the structural strength of bistrique, thereby affect the service life of grinding tool.
Utility model content
The purpose of this utility model is to provide a kind of super-hard abrasive tool for hole processing, can guarantee the structural strength of bistrique when cooling passage is set.
The technical solution adopted in the utility model is: for the super-hard abrasive tool of hole processing, comprise be provided with matrix cooling passage matrix, be arranged on the bistrique of matrix front end, described matrix cooling passage has the liquid outlet being arranged on matrix front end face, described bistrique has the counterbore coordinating for matrix front end sleeve and has the front end face towards mould front, described bistrique is provided with the bistrique cooling passage passing through for cooling fluid, and an end opening of described bistrique cooling passage communicates with described liquid outlet and other end opening is arranged in the front end face of bistrique.
The front end face of described bistrique is sphere.
On the front end face of described matrix and bistrique, the bottom surface of counterbore is close fit.
Described bistrique cooling passage is extending axially along grinding tool.
Described bistrique cooling passage has and bends and be provided with and be more than two.
Described bistrique is to be made by diamond or cubic boron nitride abrasive materials.
Described bistrique is to be fixed together by the mode of sintering, plating or welding and matrix.
The utility model adopts technique scheme for the super-hard abrasive tool of hole processing, bistrique is provided with the bistrique cooling passage passing through for cooling fluid, one end opening of bistrique cooling passage communicates with described liquid outlet and other end opening is arranged in the front end face of bistrique, therefore, injecting the cooling fluid of matrix cooling passage can discharge from the opening being arranged on bistrique front end face by bistrique cooling passage, compared with being opened in the lip-deep intake chute of bistrique with available technology adopting, the technical solution of the utility model bistrique is carried out cooling and take away grindstone dust in, guaranteed the structural strength of bistrique.
Accompanying drawing explanation
Fig. 1: the structural representation of an embodiment of the super-hard abrasive tool of processing for hole in the utility model.
The name that in figure, each Reference numeral is corresponding is called: 1 matrix, 2 matrix cooling passages, 21 inlets, 22 liquid outlets, 3 bistriques, 4 front end face, 5 bistrique cooling passages.
The specific embodiment
An embodiment of the super-hard abrasive tool that the utility model is processed for hole as shown in Figure 1, comprise matrix 1, be fixedly installed on the bistrique 3 of matrix 1 front end, matrix 1 is provided with the matrix cooling passage 2 that axially runs through matrix 1 along grinding tool, described matrix cooling passage 2 has the liquid outlet 22 being arranged on matrix 1 front end face and is arranged on the inlet 21 on matrix 1 rear end face, and described bistrique 3 has the counterbore coordinating for the front end sleeve of matrix 1 and has the front end face 4 towards mould front.
Bistrique 3 is to be made by diamond abrasive, mode and matrix 1 by sintering are fixed together, it has the part that is arranged on part around of matrix 1 periphery and laminating and is arranged on matrix 1 front end face front, the outer surface that is arranged on matrix 1 front end face front part is sphere, forms the front end face 4 of bistrique 3.In bistrique 3, be provided with the bistrique cooling passage 5 that runs through bistrique 3 along central axis, an end opening of bistrique cooling passage 5 communicates with the liquid outlet 22 on matrix 1 and other end opening is arranged in the front end face 4 of bistrique 3.
When grinding tool uses, cooling fluid enters matrix cooling passage 2 from inlet 21, by liquid outlet 22, entering bistrique cooling passage 5, the opening of being finally located in bistrique 3 front end face 4 by bistrique cooling passage 5 is discharged, and plays object fully cooling to bistrique 3 and eliminating grindstone dust.
In the above-described embodiments, the front end face 4 of bistrique 3 is sphere, and on bistrique 3, the front end face of the bottom surface of counterbore and matrix 1 is close fit, and bistrique cooling passage 5 is to run through bistrique 3 center lines axially to arrange, in other embodiment of the present utility model, the front end face 4 of bistrique 3 also can be arranged to the conical surface, and between bistrique 3 and the front end face of matrix 1, also can arrange with background technology in similar liquid containing chamber, and bistrique cooling passage 5 can arrange more than two, for example in the arc front end face 4 of bistrique 3, along corresponding sphere, two passages that are communicated with in bistrique 3 central axis places intersections are radially set, can form equally cooling passage.In addition, in above-described embodiment, bistrique 3 also can be made by cubic boron nitride, or other superhard materials make, and bistrique 3 and matrix 1 fixing also can adopt and electroplate or the mode of welding.
