Description
Technical field
The invention belongs to machinery industry Deep-Hole Drilling Technology field, be specifically related to a kind of cutting element with projection.
Background technology
Deep hole machining comprises boring, reaming, bore hole etc., is the machining operation that difficulty is larger, and in process, cutting element and the inconvenience of cutting position are observed.Because the degree of depth in hole is large, comparatively speaking, cutting element system seems thin and grows, and rigidity is little, easily sends out into deflection, causes the quality problems of workpiece.Making cutting element stablize for this reason, preventing it from departing from tram for ensureing that deep hole machining quality is extremely important.
In deep hole machining process, usually in circular knife bar (drilling rod) and the annular gap between machining hole, input the fluid with certain pressure, fluid flows into cutting region after flowing through annular gap, then flows out from the hole at drilling rod center, and liquid takes away iron filings and heat while flowing out.
Shaft portion under normal circumstances in cutting element is cylindrical.
Summary of the invention
Object of the present invention: prevent deep-hole boring instrument from wandering off, makes it be stable at correct position, improves yield rate and machining accuracy.
The present invention adopts following technical scheme to realize:
With a cutting element for projection, comprise cutting tip, shaft portion, it is characterized in that, compared with common hole machined cutting element, add bossing, the profile of bossing can be circle or oval.
Under normal circumstances, in process, cutting tip, shaft portion, bossing are positioned at the deep hole hole processed.Fluid flows through the outside of this cutting element, flows to and cuts position, and position is cut in cooling, and flows out with the hole of iron filings along cutting element inside.In process, theoretically, the center line of cutting element overlaps with the center line of institute machining hole.Shaft portion in prior art in cutting element is cylindrical, and the rear portion of cutting tip is also cylindrical, and gap that is cylindrical and that formed between machining hole is annular gap, and theoretically, gap length is equal everywhere.The present invention is with bossing, and bossing can be positioned on shaft portion, or the rear portion of cutting tip, and bossing and the gap formed between machining hole are not annular gaps, from large to small, then change from small to big again in its gap.In deep hole machining process, between cutting element and workpiece, there is relative motion, be full of liquid between the two.Therefore liquid is also driven, and moves in gap.To form dynamic pressure oil film or dynamic pressure oil reservoir when liquid flows through gap from big to small, the fluid pressure of the corresponding part in gap of convergence will increase, and produce an active force to cutting element.Bossing and processed between endoporus and form two or more gaps of restraining, each convergence gap all will produce an active force to cutting element, when the quantity and position distribution that restrain gap are suitable, fluid pressure acting in conjunction in each convergence gap, in cutting element, clamps a cylindrical component just as the scroll chuck of lathe or chuck.After scroll chuck or chuck clamp cylindrical component, namely part is in stable state, even if the power of being interfered, is usually also not easy to depart from correct position.In like manner, the cutting element with bulge-structure is also not easy to depart from correct position.
Bossing described in the present invention can be positioned at the rear portion of cutting tip, also can be positioned at the front portion of shaft portion, and machine-building unit can also manufacture an adapter sleeve, and with bossing on it, adapter sleeve connects cutting tip and shaft portion.In the process in hole, when cutting element opposite piece rotates, liquid stream crosses bossing and the convergence gap of workpiece between machining hole, produces active force, plays a role, make cutting tip and shaft portion be not easy deflection.
Often have several knife bars in deep hole machining process, shaft portion is interconnected, thus can deep hole processing, and knife bar rigidity is little in this case, is easily out of shape, and affects the crudy in hole.In order to prevent shaft portion to be out of shape, the adapter sleeve in the present invention can be installed between two shaft portion, namely by adapter sleeve, two shaft portion be coupled together.Adapter sleeve has bossing, and the active force of bossing and the liquid between machining hole makes bossing self-centering, is stable at accurate location, thus, can reduce the flexural deformation of the sagging of shaft portion and other form, reduce orifice mismachining tolerance.
The full-size of bossing should be less than the size in hole.The protruding quantity of bossing can be 2 or 3 or be greater than 3.When protruding quantity is 1, the orientation that bossing is placed should be noted, the hydraulic coupling produced by this bossing, preferably points to gib block (also known as the back-up block) position, place of deep hole tools, prevents because the existence of bossing destroys deep hole machining self-steering function.When the profile of bossing is oval, ellipse can have multiple with the correlation of the circle of cutting element column part: oval and round tangent, oval and round crossing, ellipse comprises circle etc.
The present invention relates to multiple concrete technical scheme, be described below respectively:
