Abstract

The utility model discloses a deep hole circular arc forming tool which comprises a cutter body, a cutter block and a guide block. The cutter body is formed by a cylindrical cutter body cylinder and a hole-shrinkage threaded cylinder with external threads. Two symmetrical protruding bodies with semi-cylindrical protruding faces are arranged on the circular-ring-shaped end face of the cutter body cylinder along the connecting line of the diameters of the protruding bodies, one protruding body is provided with a groove along the center line of the thickness of the protruding body, the cutter block is installed in the groove in a matched mode, and the cutter head of the cutter block is provided with a circular arc cutting edge angle. Screw holes are uniformly distributed in one semi-cylindrical plane at the two ends of each protruding body, the cutter block is fixed through screws matched with the screw holes, open grooves are formed in cylinder walls of the connecting line of the diameters vertical to the diameters and the two sides at the upper end of the cutter body cylinder respectively, and the guide block stretching out of the cylindrical face of the cutter body cylinder is fixedly connected into the open grooves. The deep hole circular arc forming tool is reasonable in structure, can be suitable for holes with machining hole diameters larger than 100mm and is suitable for core part excess materials with expensive workpiece material prices or needing to be kept completely, and bottom ends of the holes are needed by circular arc deep hole machining.

Description

A kind of deep hole circular arc molding cutter
Technical field
The utility model belongs to the machining equipment technical field, particularly a kind of deep hole circular arc molding cutter.
Background technology
Along with the development of science and technology, Deep-Hole Drilling Technology is widely used in field of machining.Deep-Hole Drilling Technology is not only the requirement of machining accuracy more and more higher, and the scope of rapidoprint is also more and more wider, and very urgent especially to the process requirements of some difficult-to-machine materials.Linearity and position accuracy demand large for materials processing difficulty, aperture, the hole are higher, and it need need to keep the part in complete heart section's clout circular arc type hole simultaneously, there is no at present and finds suitable process tool.
Summary of the invention
The purpose of this utility model is to provide a kind of deep hole circular arc molding cutter, it is rational in infrastructure, can adapt to the processing aperture greater than the hole of 100mm, and can adapt to that workpiece material is expensive maybe need keep complete heart section clout, and the bottom in hole is the deep hole machining needs of circular arc type.
the purpose of this utility model is achieved in that a kind of deep hole circular arc molding cutter, by cutter hub, cutter piece and guide pad form, cutter hub is by columniform cutter hub cylinder and have externally threaded undergauge thread barrel and consist of, annular end face at the cutter hub cylinder, along two symmetrical excrescences with half-cylindrical projecting surface are being set on the line of its diameter, one of them excrescence is along on its mid-depth line, groove being set, coordinate in groove the cutter piece that cutter head has the circular arc basil is installed, the uniform screw that arranging on one of them plane, the half-cylindrical two ends of excrescence, the screw that matches with screw is fixed the cutter piece, on the cylindrical wall of the diameter line that both sides, cutter hub cylinder upper end and above-mentioned diameter are perpendicular, open slot is being set respectively, affixed lateral surface stretches out the guide pad on the cutter hub cylinder face of cylinder in open slot.
The utility model can adapt to the processing aperture greater than the hole of 100mm, can adapt to the workpiece material costliness and maybe need keep complete heart section clout, and the bottom in hole is the deep hole machining needs of circular arc type.When using the utility model, the undergauge thread barrel of deep hole circular arc molding cutter is threaded connection is arranged on drilling rod, can process workpiece.When creeping into, utilize two guide pads as guide support, guaranteed linearity and the positional precision in hole.
The utility model is specially adapted to that the materials processing difficulty is large, the aperture is large, linearity and the high workpiece of position accuracy demand in hole.The utility model is rational in infrastructure, has realized the processing aperture greater than the hole of 100mm, and adapts to that workpiece material is expensive maybe need keep complete heart section clout, and the bottom in hole is the deep hole machining needs of circular arc type.
