Abstract
The present invention relates to the technical field of machinery, and particularly relates to the processing method for floating boring cutter guide rod. The processing method includes the following steps: selecting the 45 steel material, diameter 35 X 755 mm work blank; tempering; awarding the cutter toolbar with high toughness and ample strength; the two end sides of the machine flat end, are maintained at a total length of 750 mm; using the lengthening twist drill with a diameter of 8 mm, to drill a through hole respectively from the two end sides; the upper machine bed two-thimble clamp, the first rough turning bench, the first U-turn of the same use two-thimble clamp machine bench, and the outer circle of the machine blank, are respectively left with a margin of 1.0 mm; the fine turning bench and the outer circle of the work blank, are respectively left with a margin of 0.5mm; the rough grinding bench and the outer circle of the work bench, are left with a margin of 0.2mm; the milling trough of the upper milling machine is 60 mm X 3 mm long, the water inflow trough is 24 mm X 2 mm long, two water inflow holes are drilled with a diameter of 5 mm, one M5 screw thread is cut out; the present invention is simple to process, can be used to drill deep holes, thereby guaranteeing the smooth processing of deep drilling, increasing the processing quality of deep drilling, and lowering the production cost.
Description
Technical field
The present invention relates to mechanical skilled worker field is and in particular to the processing method of floating boring tool guide rod.
Background technology
Acquired a certain degree of difficulty using engine lathe processing deep-hole parts tool, technical difficulty when especially draw ratio is more than more than 10
Bigger.Processing single-piece or the deep hole workpiece of small lot, generally adopt the standard spiral bit of spreading, are bored on engine lathe
Cut.But when the deep hole through drilling wants further polish, make deep hole reach higher dimensional accuracy and less rough surface
During angle value, it is necessary for taking other technological measures, to solve each side technical problem of deep hole machining.Interior during deep hole turning
Hole, knife bar is thin and grow, poor rigidity, low intensity, easily produce vibration and allow knife phenomenon, and easily generation taper error, sternly
Have influence on workpiece machined surface roughness and precision again.Due to hole depth, coolant is not easily accessible, and chip removal is difficult, and such as iron filings are discharged
Have some setbacks, iron filings will scratch finished surface, have a strong impact on surface roughness, cutter meeting unstable wear, reduce service life.
The import and export of deep hole often occurs ripple, horn mouth, and turning rectilinearity is poor, so that machining accuracy is reduced.
Content of the invention
In order to the present invention that solves the above problems provide one kind can deep hole processing, and ensure that deep hole machining is smoothed out, improve
Deep hole machining quality, the processing method reducing the floating boring tool guide rod of production cost.
The processing method of floating boring tool guide rod, comprises the following steps:
The first step, selects 45 Steel materials: diameter 35 × 755 mm blank；
Second step, quenched；Knife bar is made to obtain high toughness and enough intensity；
3rd step, two end surfaces put down by car, keep overall length 750 mm；
4th step, lengthens fluted drill with diameter 8 mm, from two holes drilled through respectively；
5th step, upper lathe two thimble clamping, rough turn one section of stage, turn around same two one section of step of thimble clamping car, car hair
Base is cylindrical, each made allowance 1.0 mm；
6th step, the above-mentioned stage of smart car and blank are cylindrical, each made allowance 0.5 mm；
7th step, roughly grinds above-mentioned stage and blank is cylindrical, made allowance 0.2 mm；
8th step, upper milling machine mills out short slot 60 mm × 3 mm and water inlet flute length 24 mm × 2 mm, gets out diameter 5 mm two water inlet
Hole, tapping m5 screw thread；
9th step, with milling machine and spark live wire cutting processing knife holder slot, cooperation 30h7/g6 and 15h7/g6 of cutter groove and cutter head,
Make cutter head in rectangle cutter groove can slidably, during boring by the cutting force acting on symmetrical blade come autobalance its
Cutting position, thus obtain higher aperture precision and less surface roughness value；
Tenth step, the above-mentioned stage of fine grinding and blank are cylindrical, and to dimensional requirement, roughness is ra1.6, and its effect is to ensure that knife bar
Axiality and the symmetry of dress tool bore and knife bar；
11st step, blank cylindrical one end tapping thread hole, other end tapping thread；
12nd step, cutter head hard alloy code name is the blade deep hole processing of p01, and guide angle selected by Boring head cutting edge
8 ° -10 °, there are longer wiper edges, make processed hole obtain smooth surface and relatively low roughness；Cutter head anterior angle all using 12 °-
16 °, 5 ° ~ 6 ° of relief angle, to reduce cutting force, chip-breaker 2.5 ~ 3 mm, make that chip curling is tiny to be easily drained outside hole.
Processing method of the present invention is simple, can deep hole processing, and ensure that deep hole machining is smoothed out, improve deep hole machining matter
Amount, reduces production cost.
