In the present embodiment, that considers cutter frame mechanism is with 313 tensioner problem and space problems synchronously, also is provided with tension mechanism at said cutter frame mechanism top.Said tension mechanism comprises: be fixed on the ear formula supporting base 317 and articulation bolt 319 at knife rest mainboard 207 tops, said articulation bolt middle part is shaped on and is used to regulate synchronous belt tension and lax locking groove.
In the present embodiment; Said ear formula supporting base 317 is fixed on the top of knife rest mainboard 207 through 2 soket head cap screws 318; And regulate synchronously with 313 tensioner with lax through articulation bolt 319; Regulate moderate after, the oval styletable tight fixed bolt 320 of square toes is fixed in the locking groove of articulation bolt 319.Cunning in order to ensure regulating is fast, has two keyways on the left side of knife rest mainboard the first half, and dive key 322 is housed respectively in the keyway, through 2 slotted cheese head screws 321 dive key 322 is fixed in the keyway.Consider space problem simultaneously; The driving-chain of tool-post structure is very short; But will influence transposition disc type contour alloy gear milling cutter dish 310 tooth punching precision problems so greatly; One group of double-row conical bearing 305 is installed on cutter spindle 304, but, is made the cutter spindle motion steady in order to the radial load that the impact of bearing axial force that the tooth punching of transposition disc type contour alloy gear milling cutter dish causes and the cog belt 323 of torque motor 301, first arc tooth synchronous belt wheel 302 and 14M simultaneously causes; But and drive knife bar and 310 runnings of transposition disc type contour alloy gear milling cutter dish steadily, thereby but improved the tooth punching precision of transposition disc type contour alloy gear milling cutter dish greatly.
Said rotary table 400 front ends are provided with the 3rd servomotor 401 that is used to drive its radial feed, and servomotor connects worm gear, worm movement pair through flexible sheet shaft coupling 402, to constitute the driving mechanism of rotary table.Said the 3rd servomotor 401 is connected with power shaft 403 through flexible sheet shaft coupling 402; Power shaft 403 is connected with worm screw 407 through key 404; Thereby drive worm screw 407 worm gears 408; Worm screw is bearing on the worm screw casing 406 through bearing 405, and worm gear 408 drives workbench body 409 and does the circumgyration campaign.In order to satisfy the processing instructions for use in limited space; Need as far as possible designs simplification to be designed; Therefore in the present embodiment; Worm screw mechanical type transmission input is designed to the numerical control structure, the spline input of power shaft 403 is designed to φ 35h6 optical axis platform again, and selects for use compact conformation, elastic membrane chip shaft joint 402 easy for installation to be connected with servomotor 401.Said power shaft 403 adopts the oil sealing of dual O RunddichtringO structure, and through copper sheathing 412 being installed to improve the wearability of power shaft.Said motor flange 410 is designed to welded structure, is connected with motor flange through screw 411, thereby is fixed on the table base 415.
Said flexible sheet shaft joint 402 adopts enclosed construction, therefore on motor flange 410, has two windows, to make things convenient for flexible sheet shaft joint 402 screws fastening.
See also Fig. 7; Be center that guarantees worm-gears and the position relation that is installed in the linear guide rail on the table base 415; Between the nut seat 413 of installation worm worm gear and table base 415, transition bracket 414 is housed; And be combined with adjusting pad 416 so as when assembling the match grinding size, guarantee the needs of position relation.
Said rotary table hydraulic clamp mechanism comprises: transition nuts ring flange 418, disk 417 and nut 419 and the hydraulic jack 420 that is connected with rotary table base 415, piston 421 and clamp pull bar 422; Said disk 417 is connected with rotary table body 409 through screw with transition nuts ring flange 418, and piston 421 lower ends of said hydraulic jack are mounted on the clamping pull bar 422 in the lathe bed clamping slot.The transition nuts ring flange is connected with clamping cylinder through nut, and hydraulic drive piston 421 moves up and down in clamping cylinder 420, thereby makes clamping pull bar 422 fixing with lathe bed main body 101 in the piston stroke scope.In the present embodiment, the lower end of said clamping pull bar is designed to the circular flange structure, and it can satisfy the needs of clamping force, in the lathe bed clamping slot, moves freely in the time of making it be in releasing orientation again.The distance that clamping pull bar 422 is moved up designs in the travel range of piston 421; When rotary table need clamp; Pressure oil drives clamping pull bar 422 with piston 421 and moves up; Clamp until clamping pull bar flange upper surface and lathe bed clamping slot, thereby reach the clamped purpose of rotary table.
Because 415 times side spaces of rotary table base are limited, therefore, in the present embodiment; The shell cancellation that hydraulic clamp mechanism is bigger; And adopting a L type fixed mount 423, fixed mount one end to be fixed on the table base 415 through screw 424, the other end is fixed through the keyway on key shape plate and the separator housing 425; To prevent that the separator housing from rotating, this structure has not only satisfied the needs that use but also has saved the space.
Operation principle of the present invention is:
At first workpiece is installed on the rotary table 400, and, starts first servomotor, 102 driving rotational workbench then and directly be forwarded to the operating position workpiece and rotary table chucking, promptly cutter frame mechanism 300 under; Open the torque motor 301 on the cutter frame mechanism, but make 310 rotations of transposition disc type contour alloy gear milling cutter dish, and water cooling fluid simultaneously.At this moment, the pressure oil through hydraulic jack 420 drives piston 421 to clamp pull bars 422 and moves up, and until clamping pull bar flange upper surface and the clamping of lathe bed clamping slot upper surface, utilizes the clamping reaction force of lathe bed clamping slot upper surface that rotary table is clamped.Start second servomotor, 202 rotations on the column 200, drive ball-screw 204 and move down, and then make cutter frame mechanism be displaced downwardly to desired location, begin cut tooth punching groove before the large cylindrical gear workpiece roll flute with knife rest mainboard 207.After a monodentate cutting is accomplished; But the transposition disc type contour alloy gear milling cutter dish stop motion of cutter frame mechanism; The clamping cylinder of rotary table is unclamped, rotary table is moved backward, cutter frame mechanism moves up; At this moment, the rotation drive rotary table through the worm screw on the rotary table, worm gear carries out the operation of branch tooth.After dividing the tooth operation to accomplish, rotary table advances to the operating position once more, and the cutting of second monodentate is carried out in the lathe above-mentioned action that circulates.
