Abstract
The utility model relates to a hole processing cutter, in particular to the cutter for processing holes on an inclined surface or a conical surface. The current problem that cutters need to be frequently replaced when inclined holes are processed on the inclined surface or the conical surface, is solved through a machining cutter provided with a curved chisel edge. The cutter comprises a cutting edge, an edge strip, a holding and cutting groove and a tail handle, wherein the end of the cutting edge is provided with the curved chisel edge endowed with one or more segments of curved lines, the quantity of curved line segments is determined according to sizes of the holes to be processed on a workpiece, and the curvature of a curved line of the curved chisel edge is determined according to the value of angle of the inclined surface or the conicity of the conical surface at which the holes to be processed are positioned. The cutter achieves comparatively low production cost and convenient use, can better process the inclined holes on the inclined surface or the conical surface, and is especially suitable for processing the holes on parts with medium or low hardness.
Description
Technical field:
The utility model relates to a kind of aperture knife tool, particularly a kind of on the inclined-plane or the conical surface cutter of machining hole.
Background technology:
In recent years, along with the fast development and the extensive use of modern designs software, in order to save material, designed part shape degree of irregularity is more and more higher.And often have on the irregular contour surface and process inclined hole, particularly on inclined-plane and tapering face, process inclined hole, and the manufacturing batch of like parts is quite big.The traditional diamond-making technique of this class inclined hole is frequent polytype tool for cutting machining of changing at present, has so just caused shortcomings such as working (machining) efficiency is low, the cutter input amount is big, labor intensity of operating personnel is big.
Summary of the invention:
The utility model has solved and has processed the problem that inclined hole needs frequent replacing cutter on the present inclined-plane or the conical surface by a kind of process tool with the curve chisel edge.
The utility model is realized by following technical scheme:
A kind of inclined-plane or conical surface aperture knife tool, comprise that cutting edge, land, appearance cut groove and caudal peduncle, the cutting edge end is the curve chisel edge, the curve chisel edge is one or more snippets curve, the quantity of curved section is determined according to the hole size on the part to be processed, the curvature of curve chisel edge curve determines that according to the angle value on inclined-plane, place, processed hole or the tapering size of tapering face the method for specifically determining is:
As aperture≤a
iThe time, the quantity of curve chisel edge curved section is at b
iThe interior selection,
Work as a
i＜aperture≤a
I+1The time, the quantity of curve chisel edge curved section is at b
i-b
I+1Between select,
Wherein, a
I+1=10+a
i, b
I+1=2+b
i, i is a natural number, a
1=10mm, b
1=2;
The radius of curvature of curve chisel edge curve is ρ=R/cos θ,
Wherein: θ is the angle of inclined-plane or tapering, and R is a tool radius.
The utility model manufacturing cost is not high, easy to use relatively, can be implemented in better on the inclined-plane or the conical surface and process inclined hole, the hole processing in being particularly suitable for, on the soft part inclined-plane.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to zoomed-in view;
Fig. 3 is that the B of Fig. 1 is to zoomed-in view.
The specific embodiment:
As Figure 1-3, the utility model by curve chisel edge 1, cutting edge 2, land 3, appearance is cut groove 4 and caudal peduncle 5 is formed.
Earlier the diameter in hole and the gradient on inclined-plane, place are determined during design, according to the gradient on the diameter in hole and inclined-plane determine the curvature of curve chisel edge 1 and curved section quantity and cutting edge 2, land 3, hold the parameters of cutting groove 4, caudal peduncle 5.Determine material, hardness and the processing technology of cutter.Wherein cutting edge 2, land 3, hold the parameters of cutting groove 4, caudal peduncle 5 and determine that by conventional cutter manufacture method the curvature of the quantity of curve chisel edge 1 curved section and curve chisel edge 1 curve determines that according to following formula the method for specifically determining is:
As aperture≤a
iThe time, the quantity of curve chisel edge 1 curved section is at b
iThe interior selection;
Work as a
i＜aperture≤a
I+1The time, the quantity of curve chisel edge 1 curved section is at b
i-b
I+1Between select;
Wherein, a
I+1=10+a
i, b
I+1=2+b
i, i is a natural number, a
1=10mm, b
1=2; The radius of curvature of curve chisel edge 1 curve is ρ=R/cos θ,
Wherein: θ is the angle value on inclined-plane, place, processed hole or the taper angle of tapering face, and R is a tool radius.
The utility model adopts the cutter material machine of better performances to add and forms, and its curve chisel edge 1 curve is to utilize profile grinder to process, and all the other each positions are to utilize the general machining tool of cutter to process, and accuracy class is generally the 6-7 class precision.
