Technical field
The utility model belongs to borer technical field, and in particular to a kind of ultralong thin walled axial workpiece borer.
Background technique
In the prior art, the knife that shakes in production process is serious, and tolerance+0.3mm can not when not being able to satisfy process requirements, and processing
Guarantee.
Existing Chinese patent document CN201220653005.0 discloses a kind of novel hard alloy precision bored hole boring bar,
Its main technical schemes are as follows: novel hard alloy precision bored hole boring bar, including knife bar, cutter head and cutterhead, the cutter head installation
In on boring cutter, it is connected by knife bar with cutterhead；Cutter head and knife bar are welded using brazing, and knife bar and cutterhead are interference fit, knife bar
It is connect with cutterhead using hot charging.It is different from the utility model.
Utility model content
The purpose of this utility model is to solve the above problems, and provides that a kind of processing inner hole is deeper, tolerance is guaranteed, cooling effect
Fruit is good, and be able to solve in production process shake knife by knife problem ultralong thin walled axial workpiece borer.
To achieve the above object, the utility model provides the following technical solutions:
A kind of ultralong thin walled axial workpiece borer, centre frame and scroll chuck including knife bar and its front setting,
The knife bar is to lengthen overstriking knife bar, and one end of which is fixed on knife rest, the other end is provided with cutter accommodating slot and threaded hole, the cutter accommodating slot
Interior placement lathe tool, and the threaded hole is passed through by fixing piece and is fixed；The knife bar is hollow structure, inside sets hollow pipe
Through front and back, the hollow pipe is interior to carry out filling liquid, and one end connects external jet water spout, fills in other end alignment Lathe tool tip conduct
Cooling water pipe；The support that rolling bearing carries out part is set in the centre frame, the part other end is fixed on scroll chuck.
Further, the interior cooling water pipe that fills is a root long 500mm, and diameter is the hollow copper pipe of 8.0mm.
Further, the long 600mm of the knife bar, diameter 100mm, center bore 8.5mm.
Preferably, the fixing piece is fixture nut.
The utility model has the beneficial effects that:

Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of ultralong thin walled axial workpiece borer as shown in Figure 1, the centre frame being arranged including knife bar 1 and its front
9 and scroll chuck 8, the knife bar 1 is long 600mm, and diameter is that 100mm lengthens overstriking knife bar, and one end of which is fixed on knife rests 2, separately
One end cutting cutter accommodating slot and threaded hole, 1 center of knife bar 10mm on the upper side are drilled through, aperture Φ 8.5mm；Cast iron is supported to use centre frame 9
Rolling bearing 3 replaces the support for carrying out part 7, and 7 other end of part is fixed on scroll chuck 8；By 45 ° of brazed carbide turning tools 4
It is placed in cutter accommodating slot, is fastened lathe tool 4 with fixing piece 5 (Φ 10mm fixture nut).
1 through-hole of knife bar, an outer jet water spout of access, other end alignment are passed through using a 500 long Φ 8.0mm hollow copper pipes
Point of a knife fills cooling water pipe 6 in being used as.
The processing flow of the utility model are as follows:
7 one end of part is fixed on machine tool three-jaw chuck 8, with the rolling reequiped on centre frame 9 at other end a quarter
Dynamic bearing 3 supports, and adjusts 9 centering part of centre frame；Brazed carbide turning tool 4 is placed on lathe tool slot, is fastened with fixture nut 5；Inside fill
The outer bath of the termination of cooling water pipe 6 one, one end pass through 1 inner via hole of lengthened tool arbor, and bending pours interior bath sufficiently to fill 4 point of a knife of lathe tool,
Inner bore of part is processed to knife, guarantees inner hole+0.3mm tolerance.
Bore depth, which can be processed, in the utility model can reach 1000mm, and bearing tolerances are guaranteed solve within 0.3mm
Depths shakes knife by knife problem when processing, and cooling effect is more preferably.
The content not being described in detail in the utility model is the prior art.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
