Abstract
The invention belongs to the technical field of deep hole machining in the machinery industry, particularly relates to a hole machining tool with a rear slope structure, and aims to solve the problem of deviation of deep hole tools such as a BTA (Boring And Trepanning Association) drill in the conventional deep hole machining process. The hole machining tool comprises a cutting part, a tool bar part, a convex part and a connecting sleeve, wherein the profile of the convex part is an involute, an oblique line or other curves; in a deep hole machining process, relative movement exists between the deep hole machining tool and a workpiece, convergence gaps are formed between bumps and a processed inner hole, the convex part can be positioned on the tool bar part or on the back part of the cutting part or on the connecting sleeve; the connecting sleeve is connected with the cutting part and the tool bar part, and can be arranged between two tool bar parts. The hole machining tool has the beneficial effects that the deep hole machining tool is automatically centered under the action of hydraulic force, and is stabilized at an accurate position without deviation, so that the deep hole machining quality is enhanced.
Description
Technical field
The invention belongs to machinery industry Deep-Hole Drilling Technology field, be specifically related to the aperture knife tool that a kind of ramp structure is rearmounted.
Background technology
Deep hole processing cutter comprises drill gun, BTA bores, and deep hole tools is thin and grow, and rigidity is little, easily sends out into deflection, causes the quality problems of workpiece.Be necessary to make aperture knife tool be stable at tram, ensure deep hole machining quality.
Oil delivering unit in deep hole equipment is usually used for inputting the fluid with certain pressure in circular knife bar (drilling rod) and the annular gap between machining hole, fluid flows into cutting region after flowing through annular gap, then flow out from the hole at drilling rod center, liquid takes away iron filings and heat while flowing out.
Shaft portion in prior art in aperture knife tool 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.
And the present invention is with bossing, the bossing of involute or other shape 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 aperture knife tool 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 aperture knife tool.Bossing and processed between endoporus and form two or more gaps of restraining, each convergence gap all will produce an active force to aperture knife tool, when the quantity and position distribution that restrain gap are suitable, fluid pressure acting in conjunction in each convergence gap, in aperture knife tool, 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 aperture knife tool with bulge-structure is also not easy to depart from correct position.
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, the hydraulic coupling produced by this bossing should be noted, preferably point to gib block (also known as the back-up block) position, place of deep hole tools.Prevent because the existence of bossing destroys deep hole machining self-steering function.In order to easy to process, the profile of bossing adopt involute, oblique line or other be easy to the curve processed.
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.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 aperture knife tool 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 shaft portion 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 present invention relates to multiple concrete technical scheme, be described below respectively:
1. the aperture knife tool that a ramp structure is rearmounted, comprise cutting tip, shaft portion, bossing, it is characterized in that: the full-size of described bossing is less than the size of workpiece machining hole, bossing with process endoporus hole wall and form the gap of restraining.
2. the aperture knife tool that a ramp structure is rearmounted, comprise cutting tip, shaft portion, bossing, adapter sleeve, it is characterized in that: the full-size of described bossing is less than the size of workpiece machining hole, bossing with process endoporus hole wall and form the gap of restraining, adapter sleeve there is bossing, bossing and adapter sleeve are made into one, become a part, and adapter sleeve connects cutting tip and shaft portion.
3. the aperture knife tool that a ramp structure is rearmounted, comprise cutting tip, shaft portion, bossing, adapter sleeve, it is characterized in that: the full-size of described bossing is less than the size of workpiece machining hole, bossing with process endoporus hole wall and form the gap of restraining, adapter sleeve there is bossing, bossing and adapter sleeve are made into one, and become a part, adapter sleeve connects two shaft portion.
4. the aperture knife tool that a ramp structure is rearmounted, comprise cutting tip, shaft portion, bossing, adapter sleeve, it is characterized in that: the full-size of described bossing is less than the size of workpiece machining hole, bossing with process endoporus hole wall and form the gap of restraining, adapter sleeve has bossing, and bossing and adapter sleeve are made into integrally, become a part, adapter sleeve connects cutting tip and shaft portion, and meanwhile, adapter sleeve connects two shaft portion.
5. the aperture knife tool that ramp structure is rearmounted, as required, described bossing and cutting tip are made into one, become a part.
