Abstract
The utility model relates to a deep hole combination boring cutter provided with a support vibration absorber, and belongs to the technical field of the mechanical cutting tool. The deep hole combination boring cutter comprises a tool bar and tool bits which are connected with the tool bar. The utility model is characterized in that a tool bar cutting area is provided with a front tool bit and a back tool bit; the tool bits are arranged on the tool bar; the axial line of each tool bit is vertical to that of the tool bar; the two tool bits stand more than 20 mm apart; the axial lines of the two tool bits mutually cross with each other to form an angle of 90 degrees; each tool bit is provided with a set of supporting points, and the link for each set of the supporting points is vertical to the axial line of each tool bit. The utility model has simple, reasonable and compact structure, easy production and manufacture, low cost, convenient use and good shock absorption effect. The utility model is used in the deep hole processing, the cutting parameters of the tool edges on both sides of each tool bit are equal to each other when cutting, the cutting resistances are balanced out, thereby reducing the load of a machine tool. The cutting area is provided with a big chamfer angle, thereby facilitating the cutting scrap to expel from the hole; the tool bar is provided with a chill coolingtank which is emplaced with a tube cooler; cooling pressure water flow takes the cutting scrap out of the hole, thereby avoiding the tool bits blocking phenomenon caused by the obstructing of the cutting scrap.
Description
Technical field
The utility model relates to the boring cutter combining structure that a kind of deep hole processing is used, and belongs to the mechanical cutting tool technical field.
Background technology
In the machine cut deep hole machining, often need with special deep hole drill gun, or instrument such as drill gun formula deep-hole boring cutter, these instruments need special special customized, not only improved cost, and complexity coefficient are very big, also are not suitable for single-piece or small lot batch manufacture simultaneously.Have through hole as processing
50mm-
When 120mm length is the small lot major axis deep hole part of 2-3m, hilted broadsword that employing is made up of knife bar and cutter head or the gang tool that simply cutter arrangement is got up that does not have the strong point, add that to be easy to occur chip removal man-hour smooth and " vexed cutter ", outside smear metal row is not portalled, machining accuracy does not reach the drawing requirement, even processing can not be finished.
Summary of the invention
The purpose of this utility model is to provide a kind of economical and practical, the deep hole combination boring cutter that low cost of manufacture, complexity coefficient are little, instant effect, very practical band support vibration absorber.
The purpose of this utility model is to realize like this, band supports the deep hole combination boring cutter of vibration absorber, comprise the cutter that connects on knife bar and the knife bar, it is characterized in that the knife bar cutting zone is provided with two cutters in front and back, cutter is installed on the knife bar, tool axis and knife bar axis normal, two cutters are separated by more than the 20mm, the axis of two cutters is crossed as 90 ° mutually, every cutter is provided with one group of strong point, and the line of every group of strong point is vertical with tool axis.
The described strong point is made of bolt, nut and ball, is fastened on the knife bar by bolt, and ball is arranged in the pit of bolt end face, and the sphere of ball exceeds the nut plane.Described knife bar is provided with knife bar clamping cover, and knife bar clamping cover is sleeved on the knife bar.Knife bar cutting zone diameter is greater than more than the diameter 10mm of knife bar installation region.The knife bar cutting zone is provided with big chamfering near place, knife bar installation region.Knife bar is provided with cooling bath.
The utility model is simple in structure, and is rationally compact, manufactures easily, and cost is low, and is easy to use, good damping effect.Use the utility model band to support the deep hole combination boring cutter of vibration absorber, when cutting, cutter both sides cutting edge equated by bite, one of cutting edge up, another down, cutting force is just in time offset, and has reduced the load of lathe, afterbody in the Tool in Cutting zone, be provided with very big chamfering, help in the very smooth tap of smear metal, knife bar is provided with cooling bath
, promptly the cooling water current that form certain pressure are taken smear metal outside the hole out of, when having avoided deep hole machining because of going out bits not freely " vexed cutter ".The strong point that has had bolt, nut and ball to constitute, adding man-hour just can " cutter relieving " and produce tapering, can not vibrate yet, and influences crudy.Ball has been installed in the bolt the inside, and the contact-making surface that makes the strong point almost is a point, and the linearity that processing is portalled can reach 0.1mm, and fineness can reach 3.2um.
