Description
Technical field
The utility model is related to bore hole rounding machine cutter field, composite cutter is cut with scissors in especially a kind of milling of bore hole machining tapered hole
Tool.
Background technology
The more advanced method of the one-armed direction device connecting plate of processing in industry at present is, Boring machine fixed using workpiece
The left-handed right cut taper milling cutter that high speed steel material is installed on main shaft, to process the connecting plate of one-armed direction device, the processing of upper plate needs
A taper milling cutter, lower plate is wanted then to need three taper milling cutters while processing, still, since connecting plate blank is through forging and pressing or casting
What the method made was fabricated, it is restricted by production technology, allowance is bigger, substantially increases production cost, uses taper
Milling cutter directly processing does not meet the requirement of milling cutter, be easy to cause cutter and drastically wears even tipping and shake the defect of knife,
Not only the accuracy of processing had been reduced, but also has greatly reduced the service life of milling cutter, how to have extended cutting-tool's used life, has reduced life
The cost of production becomes insoluble technical barrier for a long time, in view of the foregoing, now researches and develops a kind of bore hole machining taper
Compound tool is cut with scissors in the milling in hole.
Utility model content
The purpose of this utility model is to overcome deficiency in the prior art, a kind of bore hole machining tapered hole is provided
The defects of compound tool is cut with scissors in milling, and preferably the epidermis of reply casting and forge piece is hard, stomata, sand holes, substantially increases cutter
Service life reduces production cost, improves processing quality.
The utility model to achieve the goals above, adopts the following technical scheme that：A kind of milling of bore hole machining tapered hole
Cut with scissors compound tool, be by：Hilt, groove, annular groove, cutter hub, alloy cutter head, taper reamer, cylinder slotting cutter, is got over screw hole
Journey slot, circular groove, connecting pole, raised line, bar-shaped trough are constituted；Hilt is the cylinder that one end diameter is more than the other end, and hilt is straight
Annular groove is arranged in the lateral screw hole of the small one end setting of diameter, the big one end periphery of hilt diameter, close to hilt diameter it is big one
End periphery is uniformly distributed at least two grooves, and groove is inner concave arc surface, and connecting pole is round estrade, the big one end of hilt diameter and company
It connects the small one end of column diameter and corresponds to and fix, cutter hub is that one end of round estrade is arranged cylinder and constitutes, and cutter hub round estrade diameter is big
One end fixation correspondings with one end that connection column diameter is big, the periphery of cutter hub are uniformly distributed at least six bar-shaped troughs, it is described at least
At least six raised lines are constituted between two adjacent bar-shaped troughs of six bar-shaped troughs, cutter head is arranged in the upper right corner of the cross section of raised line
The boundary line of slot, the round estrade of the outer periphery cutter hub of at least six raised lines and cylinder is arranged grinding undercut, in cutter head slot
Alloy cutter head is set, alloy cutter head is divided into taper reamer and cylinder slotting cutter along grinding undercut from left to right, hilt, cutter hub and
The axial line of connecting pole overlaps, and hilt, cutter hub and connecting pole are integrally formed.
At least six bar-shaped troughs are less than the length far from circle centre position one end close to the length of circle centre position.
The small one end of the cutter hub round estrade diameter is corresponding with cutter hub cylindrical member at one end to be fixed, and cutter hub round estrade diameter is small
One end diameter it is equal with the diameter of cutter hub cylinder.
Circular groove is arranged in the other end circle centre position of the cutter hub cylinder.
The cross section of at least six raised lines is right-angled trapezium, and the center of circle of cutter hub is located at least six raised line right angles ladder
The intersection point of the extended line of the right-angle side of shape.
The utility model has the beneficial effects that：The utility model says that the left-handed right cut taper milling cutter of original high-speed steel is substituted for
Leading portion is cylinder slotting cutter, the welding hard alloy compound tool that back segment is taper milling cutter, when processing, is added by the slotting cutter of leading portion
Work goes out the larger allowance of bottom outlet before fraising, and the reaming of internal taper hole is then partially completed by the taper milling cutter of back segment.This
Sample makes allowance reasonably be distributed, in practice it has proved that, since alloy cutter has red hardness more better than high-speed steel tool
And wearability, therefore the defects of the epidermis that can preferably cope with casting and forge piece is hard, stomata, sand holes, substantially increase cutter
Service life, reduce production cost, improve processing quality.
