Description
Technical field
The present invention relates to the cutters that machining uses, more particularly, to the bore hole machine clip variable-position for being suitable for large-sized structural parts
Cutter.
Background technique
Mining fully-mechanized mining equipment hydraulic support is large welded structures part, is welded by high strength steel plate, crucial hinge hole
Aperture and the ratio between hole depth > 4 cause hinge hole in Boring since welding capacity is larger so that overall deformation is larger
Surplus is larger.Current boring bar is steel boring bar, and steel boring bar only just can guarantee when boring bar hangs length and boring bar diameter ratio≤4
Bore hole quality；When boring bar hangs length and boring bar diameter ratio > 4, boring system rigidity is poor, and cutter holds during Boring
It is also easy to produce vibration, not can guarantee bore hole quality and efficiency.To solve this problem, the high-speed steel that reconditioning can only be used sharp at present
Cutter or hard alloy cutter carry out machining, and when machining will also reduce cutting depth and the amount of feeding, therefore exist and cut
Cut that processing quality is unstable, deficiency of low efficiency；Meanwhile the high-speed steel tool or hard alloy cutter sharp using reconditioning, it is right
Operator's reconditioning technical requirements are higher, and reconditioning cutter also temporary mass efficient working time；Because reconditioning cutter can not be into
Row coating treatment, leads to that tool wear is very fast, the service life is lower, it is difficult to guarantee the bore hole efficiency and quality of this large-sized structural parts.
Summary of the invention
It is an object of that present invention to provide a kind of Boring machines suitable for large-sized structural parts to press from both sides indexable tool, realizes efficient, high
Quality is hinged hole boring processing.
To achieve the above object, the present invention takes following technical proposals:
Boring machine of the present invention suitable for large-sized structural parts presss from both sides indexable tool, including the knife bar for connecting boring bar, indexing
Blade and compression connector composition；Installing locating slot is offered positioned at the knife bar cutting end, the transposition blade passes through described
Connector is compressed to be arranged in the installing locating slot；Transposition blade is made of three groups of cutting edges, cutting edge described in every group by
Main cutting edge and end cutting edge composition；The plane included angle between the major and minor cutting edge in every group of cutting edge is 90 ° -100 °,
Plane included angle between two adjacent major cutting edges is 60 °, and the tool cutting edge angle of main cutting edge is 70 ° -80 °, and the relief angle of main cutting edge is
5°-11°。
The slot bottom shape of the installing locating slot and the flat shape of the transposition blade match, the side of installing locating slot
Wall is the inclined-plane being inclined outwardly, and the tilt angle on the inclined-plane is 5 ° -11 °.
Each main cutting edge, which is parallel to, in the upper surface of the transposition blade offers chip-breaker, the chip breaking respectively
Slot is compression molding or reconditioning molding；The cutting edge of each main cutting edge is provided with 20 ° -30 ° of negative chamfered edge, the negative chamfered edge
Width is 0.2mm-0.3mm.
The compression connector is housing screw.
Advantage major embodiment of the present invention is in the following areas:
1, the transposition blade that the present invention uses can adjust blade material and coating, blade according to processing object convenient for coating treatment
Service life is long, only the i.e. indexable replacement cutting edge of housing screw need to be unclamped after blade abrasion, especially to batch boring large scale structure
When part hinge hole, high in machining efficiency, continuity and quality stability are good；
2, chip-breaker grinding-shaping or can take compression molding, and chip-breaker balances the sharpness and impact resistance of main cutting cutting edge
Can, big cutting-in boring processing is especially adapted to, chip breaking effect is good, and iron filings do not wind knife bar, does not influence bore hole quality；
3, main cutting edge uses 70 ° of -80 ° of tool cutting edge angles, guarantees under big cutting-in operating condition, increases main cutting edge and work piece interface
Product, reduces the concentration of cutting force, improves the impact resistance of blade and the stability of cutting；
4, when boring bar hangs the large-sized structural parts hinge hole bore hole of length and boring bar diameter ratio > 4, alternative hard closes the present invention
Golden boring with tool improves bore hole efficiency and quality compared with hard alloy cutter, reduces to boring operation personnel's reconditioning cutter
Skill requirement ensure that bore hole efficiency and quality.
