The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion of doing based on the utility model, all falls into the utility model protection domain.
As shown in accompanying drawing 1 ~ 6, the utility model comprise tool-post structure 1, radially fastening bolt 2, cutter 3, a secondary cutter 4, axially fasten bolt 5, tripping sleeve 6, put cutter groove 7, what described tool-post structure 1 was provided with axle center puts cutter groove 7, a described cutter 3 is arranged to put after compressing by tripping sleeve 6 in cutter groove 7 and axially fastens on tool-post structure 1 by axially fastening bolt 5, and described secondary cutter 4 is arranged to put in cutter groove 7 by fastening bolt 2 radially and is longitudinally anchored on tool-post structure 1.
A described cutter 3 is arranged in parallel in putting cutter groove 7 with secondary cutter 4, and the blade of the two and axial line are in same plane.
A described cutter 3 and the blade of secondary cutter 4 be 180 ° arrange and center line perpendicular to tool-post structure 1, described secondary cutter 4 is longer than cutter 3 No. one time.
Described tripping sleeve 6 comprises splicing sleeve 9, block bearing 10, both interference fit.More firm to guarantee processing stability for splicing sleeve 9 is coordinated with block bearing 10, can take to soak after splicing sleeve 9 evenly heats up it and coordinate with block bearing 10 again with deep fat, after room temperature is cooling, assemble again use.
Described splicing sleeve 9 is the one in copper, the pig iron, spheroidal graphite cast-iron structure.Preferably chalocopyrite structure.
Described block bearing 10 is needle bearing.
Described tripping sleeve 6 outer ends arrange axle end baffle plate 8.
Described axle end baffle plate 8 is gland structure, its large end face and splicing sleeve 9 outer face matched in clearance, and small end face pushes against circle within block bearing 10.Large end face and splicing sleeve 9 outer face matched in clearance, when utilizing tripping sleeve 6 to rotate, effectively prevent that steel cuttings from falling in block bearing 10, and small end face pushes against circle within block bearing 10, prevents that bearing from producing and moving axially in the time bearing axial load.
The large end face of described axle end baffle plate 8 and the gap of splicing sleeve 9 are 0.2 ~ 0.3mm.In the time of assembling, check gap with clearance gauge, guarantee in 0.2 ~ 0.3mm, be convenient to tripping sleeve 6 and rotate flexibly.
the utility model operation principle and the course of work:
The utility model has adopted overall tool-post structure structure, the arranged Double-blade that axle center was set on tool-post structure is put cutter groove, and by cutter and secondary cutter simultaneously opposed type be arranged at and put in cutter groove, cutter adopts double-pole structure, short sword is set above, when completing first reaming, tool base is to the effective tightening of second rimmer knife.This double-pole structure has realized the technological requirement of clamped one time (feed) second reaming, and cutter bite is large, has greatly improved working (machining) efficiency, the mode that adopts rectangular thread to be connected between this device and lathe dress knife rest, simple in structure, it is convenient to install, in order to improve the stability of cutter, prevent in process the center cutter shakiness larger problem of beating, ad hoc tripping sleeve and axle end baffle plate are double-deck to be compressed, axle end baffle plate buckle closure is lived the gap of tripping sleeve simultaneously, effectively prevent that slag bits from falling into, guarantee the location of tripping sleeve, tripping sleeve has adopted and can bear the good structure of deformability, it is more firm to guarantee processing stability for splicing sleeve is coordinated with block bearing, having adopted deep fat to soak after splicing sleeve evenly heats up it coordinates with block bearing again, after room temperature is cooling, assemble again the mode using, the preferred chalocopyrite structure of splicing sleeve, effectively prevents that cutter is stuck by slag bits and cannot take out at work, particularly secondary cutter has also used a cutter to be located at side by side outside in axial compression, plays the effect of secondary compression, knife rest side arranges high pressure scarfing cinder water pipe, carries out in time clear bits and effective temperature-reducing automatically simultaneously in work.
When work, secondary cutter is arranged at and puts cutter groove inner side, longitudinally be anchored on tool-post structure by fastening bolt radially, again a cutter is also arranged to the same cutter groove inner side of putting, after compressing by axle end baffle plate and tripping sleeve, by axially fastening bolt shaft to being anchored on tool-post structure, the external cutter head of secondary cutter is longer than the cutter head of a cutter, then tool-post structure is fixedly arranged on to depth drill equipment, open high pressure and consider clearly water pipe to be worth doing, get final product work.Further illustrate as an example of H9-018 type deep hole drilling and boring machine example, use after this device, machine tooling scope has covered diameter of bore 80 ~ 280mm, has broken through our factory's maximum in traditional sense and can only process the bottleneck of 160mm deep hole, successfully processed Φ 270mm hollow shaft, deep hole processes at one time.This device tool-post structure and axle end baffle plate adopt 45 steel, use blank 20kg, 8.36 yuan/kg of unit price, totally 168 yuan; 80 yuan of 1 meters of brass bearing cover; 100 yuan of 1 meters of needle roller block bearing; 1000 yuan of the processing charges such as line cutting, car, milling, this device adds up to cost 1348 yuan of left and right; And adopt outsourcing molding cutter, in 160 ~ 280mm inside diameter ranges, must at least use the cutter of 6 kinds of specifications (to consider cutting output, every increase 20mm must change one grade of molding cutter), only the cost of charp tool just needs 3000 ~ 5000 yuan of left and right, and processing aperture is larger, and cutter is more difficult purchases.
