Description
Technical field
The invention belongs to machinery industry Deep-Hole Drilling Technology field, and in particular to a kind of to have the function of that anti-bias external chip discharging is deep
Hole drill.
Background technology
Deep hole machining is the larger machining operation of difficulty, in process cutting element and cutting parts inconvenience see
Examine.Because the depth in hole is big, in contrast, cutting element system seems thin and grows that rigidity is small, and easily hair causes workpiece into deflection
Quality problems.Prevent cutting tool and manufacturing process system from deforming, stabilize it in correct position, for ensureing deep hole machining
Quality is extremely important.
Deep hole tools include bta deep hole drilling and outside chip removal deep hole drill.Bta deep hole drilling is also known as drill gun.
During deep hole machining, usually fluid of the input with certain pressure, fluid flow through cutting region, cooling and lubricating knife
Tool, then flows out with iron filings, realizes automatic chip-removal.
The content of the invention
The purpose of the present invention：Prevent bta deep hole drilling from deforming and wandering off, stabilize it in correct position, added by raising
The percentage of A-class goods and machining accuracy of work deep-hole parts.
The present invention adopts the following technical scheme that realization：
There is anti-bias outside chip removal deep hole drill, including tool parts 1, shaft portion 2, the tool parts are located at
In workpiece 1, rotated relative to workpiece, and make feed motion.Cutting fluid 6 is flowed into from the mesoporous 5 of shaft portion, flows through cutter part
Point, cooling and lubricating cutter, subsequent cutting fluid is flowed out with the V-shaped groove 7 of chip 4 from tool parts and shaft portion.
The outer surface of existing bta deep hole drilling shaft portion, including V-shaped groove and smooth arc-shaped surface.V-shaped groove corresponds to
About 120 degree of angle.Corresponding about 240 degree of the angle of smooth arc-shaped surface.
Shaft portion is subject to deflection deformation during deep hole machining, has many factors to cause its deformation.Firstth, it is existing
There is bta deep hole drilling that there is asymmetrical structure, unsymmetric structure easily produces centrifugal force when rotating at a high speed, and centrifugal force is vertical
In knife bar axis, knife bar is set to occur bending and deformation.Secondth, the gravity of shaft portion can cause the deformation of shaft portion.3rd, cut
The deformation of shaft portion can also be caused by cutting the active force of power liquid and other perturbed forces.So the deep hole processed easily occurs partially
Tiltedly, straightness, verticality, the depth of parallelism, concentricity easily exceed the margin of tolerance.
The present invention processes indenture 1 and indenture 29 in the column part of knife bar, indenture one during deep hole machining
8 and indenture 29 form wedge shape space with machined bore area, will enter from the part cutting fluid of tool parts outflow above-mentioned
Two wedge shape spaces.Since shaft portion rotates at a high speed relative to inner walls of deep holes, cutting fluid will be dragged into wedge shape space, and from wedge
The small end of the big end flow direction wedge shape of shape.Wedge effect raises the fluid pressure made in wedge shape space, outside wedge shape space
The pressure of liquid.The Machine Design (the 8th edition) your good chief editor Higher Education Publishing House of Pu publishes describes wedge shape space Shi Le liters
High principle, is specifically shown in the fluid lubrication Introduction on Principle parts of page 58 and the Liquid Power Lubrication Radial Bearing design meters of page 288
Calculate.
Fluid pressure rise in indenture 1 and indenture 29 in the present invention, to tool parts and shaft portion particularly knife bar
Part acts power, the external force for making a concerted effort to cause shaft portion to deform complete or partial counteracting of the active force, so that
Knife bar deformation is prevented, knife bar is in correct position all the time, ensures the quality of institute's deep hole processing.
Another scheme is that wedge-shaped protrusion 1 and wedge-shaped protrusion 2 11 are processed on the periphery of shaft portion, its
Wedge shape space is formed with bore area, fluid pressure rise in wedge shape space when shaft portion rotates, to tool parts and knife bar
Part particularly shaft portion acts power, which causes shaft portion to become complete or partial counteracting with joint efforts
The external force of shape, so as to prevent knife bar deformation, makes knife bar be in correct position all the time, ensures the quality of institute's deep hole processing.
The third scheme is that one or more rectangular preiections 12 are processed on the periphery of shaft portion, itself and deep hole
Inner wall contact can prevent shaft portion from deforming.
Indenture quantity, wedge-shaped protrusion quantity in the present invention can also be one or three or more than three.
The present invention has following technical characteristic in a word：
