Work=100+1.443126=101.443126 rev/min
So knowing the real work rotating speed is 101.443126 rev/mins, the rotating speed that is to say the radial feed servomotor will remain on the radial feeds of 101.443126 rev/mins of cutters just can realize processing taper pipe thread accurately the time.
Do the technology that feed motion realizes screw thread processing as for cutter along the machine tool chief axis axis direction, all thread chasing machines all possess, and do not give unnecessary details in the utility model.
Pipe lathe with radial feed function described in the utility model, its technological core is that research has a plurality of facing heads of realizing the radial feed slide plate, utilize gear drive and Bevel Gear Transmission and screw-nut body, for each radial feed slide plate drives respectively, rotatablely moving of motor is converted into the radial feed slide plate when rotating, realizes separately independently radial feed motion along with facing head.On each radial feed slide plate knife rest is housed, thereby realizes under the motionless situation of pipe turning processing being carried out in its end, particularly the taper thread of tube end is processed.
Lathe mainly includes: main motion motor, feed servo motor, main spindle box, facing head, anchor clamps, lathe bed and anchor clamps slide plate and casing slide plate.Lathe headstock 3 is fixedly mounted on can be vertically moving on the slide plate 23 of moving on the lathe bed 22, and pipe clamp is installed in by guide rail and can realizes realizing that the self-centering of pipe steps up on the anchor clamps slide plate that left and right sides synchronous on-off moves.
The outside of described lathe headstock 3 is provided with 1, three radial feed servomotor 2 of a main motor.Main motor by belt pulley transmission of power to main transmission gear wheel 11, main transmission gear wheel 11 and main shaft 5 are connected and fixed by key, six feeding output shafts 12 are installed in by rolling bearing on the former of gear wheel 11, and are parallel with the axis of main shaft.Therefore, when main transmission gear wheel 11 rotation, will drive the main shaft rotation of taking exercises, the locus of six feeding output shafts 12 is done the gyration synchronous with main motion together simultaneously, because each feeding output shaft 12 also will be accepted to rotatablely move from feed servo motor 2, so each feeding output shaft 12 comes down to doing planetary motion.
Lathe of the present utility model has three feed servo motors 2 and links to each other with three feeding input gears 6 respectively, three feeding input gears 6 are meshed with the input end gear of three duplicate gears 7,8,10 respectively, three duplicate gears 7,8,10 sky layer by layer are enclosed within on the main shaft, the gear of output end of three duplicate gears 7,8,10 is meshed with two output feed gear wheels 9 respectively, output at three duplicate gears just has six output feed gear wheels 9 to be meshed with it like this, thereby six output feed gear wheels form three groups of driving-chains.As shown in Figure 1, output feed gear wheel 9 process feeding output shafts 12 link to each other with the input driving gear of bevel gear, the driven gear of bevel gear is fixedly mounted on the nut of radial feed screw pair 15, and the two ends of feed screw pair 15 link to each other with radial feed slide plate 16 respectively.When feed servo motor 2 rotates, drive duplicate gear 7,8,10 and rotate by feeding output shaft 4, feeding input gear 6.Duplicate gear 7,8,10 arrives output feed gear wheel 9 and feeding output shaft 12 to transmission of power, thereby the nut that the driving radial feed screw is paid rotatablely moves.And the nut of radial feed screw pair 15 is axially fixed on the capstan 17, has therefore just driven the radial feed screw motion, has driven feed slide 16 and has done the radial feed motion.
Anchor clamps 18 and anchor clamps slide plate 20 can about relative being synchronized with the movement, clamp base 21 is fixed on the lathe bed 22, main spindle box 3 is installed in and vertically moves length feed servomotor 25 drive length feed leading screws rotations on the slide plate 23, axially moves thereby driving vertically moves slide plate 23.Cutter is parallel to the vertically moving of main spindle box of passing through that vertically moves that tube axis does and realizes when cutting like this.
Because the driving-chain of the axial feed machining screw of lathe, and digital control scheme is consistent with other Digit Control Machine Tool.Therefore repeat no more.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
