Abstract
The invention relates to a cutting tool used for machining, in particular to a three-blade drilling reamer, which comprises a cylindrical cutter handle, a first cutting end face edge, a second cutting end face edge, and an axial edge, wherein a first step is arranged on one end face of the cutter handle; a second step is arranged on the first step; a third step is arranged on the second step; the first cutting end face edge is arranged on the first step; the second cutting end face edge is connected with the first cutting end face edge and an angle is formed between the second cutting end face edge and the first cutting end face edge; the axial edge is arranged along the axial direction of the cutter handle; one end of the axial edge is connected with the second cutting end face edge; the other end of the axial edge is connected with a step face extending to the first step. When a workpiece is turned, the first cutting end face edge, the second cutting end face edge and the axial edge turn the workpiece, so that the turning of the workpiece can be completed at one step, and cuttings generated by turning are discharged from the step face. The three-blade drilling reamer is reasonable in structure and good in use effect.
Description
Technical field
The present invention relates to the cutter that machining uses, be specifically related to a kind of three cutting drill reamers.
Background technology
Current processing step hole, the general vertical machining centre that adopts is processed, and vertical Cutter Body Processing with Machining Center stepped hole needs through several procedure, also need tool changing simultaneously, production efficiency receives impact, and a set of vertical machining centre is expensive, increases the cost of enterprise.
Summary of the invention
For above-mentioned technical problem, the invention provides and a kind of reduce manufacturing procedure, in process without the need to change cutter for processing step hole three cutting drill reamers.
Technical scheme of the present invention is as follows:
Three cutting drill reamers, comprise cylindrical knife shank, the first drill bit, the first wiper edges, the second reamer, the second wiper edges, the 3rd reamer and the 3rd wiper edges is provided with successively to the other end in one end of cylindrical knife shank, the external diameter of the first drill bit is less than the external diameter of the first wiper edges, the external diameter of the first wiper edges is less than the external diameter of the second reamer, the external diameter of the second reamer is less than the external diameter of the second wiper edges, the external diameter of the second wiper edges is less than the external diameter of the 3rd reamer, and the external diameter of the 3rd reamer is less than the external diameter of the 3rd wiper edges.
Described second wiper edges and the 3rd wiper edges are the wiper edges of taper.
The tapering of the second wiper edges and the 3rd wiper edges is 3 ° to 5 °.
The periphery of described cylindrical knife shank is provided with annular knurl.
Have employed such scheme, the first drill bit, the first wiper edges, the second reamer, the second wiper edges, the 3rd reamer and the 3rd wiper edges is provided with successively to the other end in one end of cylindrical knife shank, the external diameter of the first drill bit is less than the external diameter of the first wiper edges, the external diameter of the first wiper edges is less than the external diameter of the second reamer, the external diameter of the second reamer is less than the external diameter of the second wiper edges, the external diameter of the second wiper edges is less than the external diameter of the 3rd reamer, and the external diameter of the 3rd reamer is less than the external diameter of the 3rd wiper edges.After processing first hole by the first drill bit, by the first wiper edges, first hole is repaired, make the smooth surface in first hole.After processing second hole by the second reamer, by the second wiper edges, second hole is repaired, make the smooth surface in second hole.After processing the 3rd hole by the 3rd reamer, by the 3rd wiper edges, the 3rd hole is repaired, make the smooth surface in the 3rd hole.Because the first drill bit, the first wiper edges, the second reamer, the second wiper edges, the 3rd reamer and the 3rd wiper edges are integral type, therefore, without the need to changing cutter in processed formula, have the advantages that manufacturing procedure is few.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1 is the 3rd wiper edges for cylindrical knife shank, 2 be the first drill bit, 3 be the first wiper edges, 4 be the second reamer, 5 be the second wiper edges, 6 is the 3rd reamer, 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1, three cutting drill reamers, comprise cylindrical knife shank 1, and the periphery of cylindrical knife shank is provided with annular knurl 1a.The first drill bit 2, first wiper edges 3, second reamer 4, second wiper edges 5, the 3rd reamer 6 and the 3rd wiper edges 7 is provided with successively to the other end in one end of cylindrical knife shank 1, the external diameter of the first drill bit 2 is less than the external diameter of the first wiper edges 3, the external diameter of the first wiper edges 5 is less than the external diameter of the second reamer 4, the external diameter of the second reamer 4 is less than the external diameter of the second wiper edges 5, the external diameter of the second wiper edges 5 is less than the external diameter of the 3rd reamer 6, and the external diameter of the 3rd reamer 6 is less than the external diameter of the 3rd wiper edges 7.Second wiper edges and the 3rd wiper edges are the wiper edges of taper.The tapering of the second wiper edges and the 3rd wiper edges is 3 ° to 5 °.
