Abstract
The utility model belongs to the technical field of machining equipment, and particularly relates to a deep hole trepanning drill. A cylindrical trepanning drill body is composed of a cutter body cylinder and a diameter-shrinkage threaded cylinder. Two mutually-perpendicular diameters are arranged on the end face of the front end of the cutter body cylinder. A first cutter tooth and second cutter teeth are respectively arranged on the circular ring end face of the cutter body cylinder in one diameter. Symmetrical guiding blocks are respectively arranged on the circular ring end face of the cutter body cylinder in the other diameter. The first cutter tooth is one cutter tooth. The second cutter teeth are two cutter teeth which are arranged in the diameter from interior to exterior, wherein the inner cutter tooth is higher than the outer cutter tooth by 0.3mm. Square-tooth threads are arranged on the diameter-shrinkage threaded cylinder. The deep hole trepanning drill is reasonable in structure, can be suitable for machining holes with the hole diameters larger than 100mm, and can also be suitable for the requirement for machining deep holes, wherein the workpiece material cost of the deep holes is high, or the complete central remaining materials of the deep holes are required to be reserved.
Description
Technical field
The utility model belongs to the machining equipment technical field, particularly a kind of deep hole cylindrical drill.
Background technology
Along with science and technology development, the deep hole machining technology is widely used in field of machining.The deep hole machining 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 big for materials processing difficulty, aperture, the hole are higher, and it need need to keep the part of complete heart portion clout simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of deep hole cylindrical drill, and it is rational in infrastructure, can adapt to the processing aperture greater than the hole of 100mm, and can adapt to the expensive deep hole machining needs that maybe need keep complete heart portion clout of workpiece material.
The purpose of this utility model is achieved in that a kind of deep hole cylindrical drill, columnar jacking drill body is made of cutter hub tube and undergauge thread barrel, two orthogonal diameters on the cutter hub tube front end end face, wherein along on the cutter hub tube annulus end face of a diameter preceding first cutter tooth and second cutter tooth being set respectively, along the guide pad that symmetry is being set respectively on the cutter hub tube annulus end face of another diameter, first cutter tooth is a cutter tooth, two cutters tooth of second cutter tooth for arranging from inside to outside along diameter, wherein interior cutter tooth is arranging square thread than the high 0.3mm of outer cutter tooth at the undergauge thread barrel.
Cylindrical drill is annular drill again, be a kind of material-saving, economize the deep hole processing cutter of the energy, efficient, high-quality, other drill bit of productivity ratio exceeds tens times, can adapt to the aperture greater than the hole of 100mm, the expensive deep hole machining needs that maybe need keep complete heart portion clout of workpiece material.When using the utility model, the jacking drill body is installed on the drilling rod by being threaded, and adopts side set to cut to realize the branch bits.
The utility model is rational in infrastructure, realized the processing aperture greater than 100mm, and has adapted to the expensive deep hole machining needs that maybe need keep complete heart portion clout of workpiece material.
