Transmission principle: line cutting workbench by X and Y to two linear axis form the cross coordinate setting table, when using with pole of rotation coordinate interpolation device, remove the power supply of X to coordinate motive power source, be connected on the stepper motor 2 of pole of rotation coordinate interpolation device, the pulsed drive stepper motor 2 that system sends, rotary power passes to first worm screw 5 on the power transmission shaft 4 by shaft coupling 24, after first worm gear 7 that is meshed with first worm screw 5 slows down for the first time, by second worm screw 8 and second worm gear, 12 secondary speed-reducings that are arranged in the workbench housing 9 on the deboost axle 6, finally obtain 6000: 1 gearratio, deboost axle 6 rotations drive driving gear 13, give the driven gear that is engaged with 14 rotations transmission of power, the gearratio of driving gear 13 and driven gear 14 is 1: 1, finally drives main shaft 11 rotations, and so far driving-chain finishes.Because the worm and gear auxiliary driving has irreversible characteristic, the adjustment of workpiece for convenience, specially be provided with the hand-screw jackscrew 41 that driving-chain is disconnected from driving gear 13, tighten hand-screw jackscrew 41 and power can be passed to main shaft 11 by jackshaft 10, unscrew hand-screw jackscrew 41 and can stir main shaft 11 with hand.During the cutting tapering, size according to angle, be converted into the thickness of angle adjustment piece 20, that is to say the workpiece that just can cut different taperings by the angle adjustment piece 20 of changing different-thickness, after more finishing changing angle adjustment piece 20, suitably tighten angle lock jack panel 45, just finished preset the tapering cutting.
For the structure of this device is described better, existing cutting process with regard to accurate cone is done one and is specifically set forth:
The first step, this Unit Installation makes the sine gauge device be in level " 0 " degree position, with a side of dial gauge alignment sine gauge device, and fixedly sine gauge is installed on the line cutting workbench;
Second step, the debugging at the main shaft gyration center of this device, on rotary table 15, connect a standard cylinder (diameter is more than 80mm), unclamp hand-screw jackscrew 41 and rotate rotary table 15, overlap with the center of circle of table calibration standard cylinder and the circle of rotary table 15, cut with line cutting molybdenum filament 4 of symmetries on the cylindrical of standard cylinder and lean on, find out rotary table 15 and be positioned at position on the line cutting workbench, and record, screw hand-screw jackscrew 41 after the adjustment;
In the 3rd step, the adjustment of workpiece tapering calculates the thickness of angle adjustment piece 20 according to triangle Pythagorean theorem, and it is installed on the sine gauge portable plate 16, screws angle lock jack panel 45;
The 4th step, calculate starting point, because during the tapering cutting, the sine gauge device is not spent in level " 0 ", nature can make the centre of gyration and the line cutting workbench out of plumb of main shaft 11 like this, can be according to thickness of workpiece, sine gauge centre of support and main shaft gyration centre distance, the molybdenum filament that calculates behind the angle beat plays cutpoint;
In the 5th step, program composition is example with 3B format program commonly used, by P=r (equation of the circle of a central coordinate of circle under the polar coordinates initial point in the polar coordinates, if the central coordinate of circle of circle not at the polar coordinates initial point, equation is
) as can be known, when how polar angle changes, the utmost point directly is a constant.So cutting the program of a circle on this device is exactly a straight-forward program in fact.Be B B B MGXL1 (formula 1).The gearratio i=6000 of this device: 1 and 120 pulses make motor change 1 circle (this is the parameter by motor and driver decision), axle is turned around just need the M=120Xi=720000 pulse, in order to make the starting point of cutting that good fineness be arranged, can when programming, add several millimeters equivalent; (program of 3B form is similar to international G code, all is a kind of program format of digital control processing, needn't investigate, original text be described in technical leading to.)
In the 6th step, cutting plays cutpoint according to the molybdenum filament that calculates, and opens high frequency pulse power supply and cooling fluid, shakes workbench to molybdenum filament and plays cutpoint, and working procedure begins cutting.
Cut out the gear sample that conforms with required precision at last with these anchor clamps: circularity has only 0.01mm, on outward appearance fineness, do not seen the commutation striped. in the clamping location that anchor clamps are lived, and silk is mended all very convenient. in design, we find that this anchor clamps structure can be expanded into any geometric tapering cutting theoretically in fact in the process of use anchor clamps.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
