The utility model is provided with three digital control coordinate axes which comprise two revolution axes (the X-axis, the Y-axis) and a straight axis (the Z-axis), and the three axes can be controlled by preset program so as to accomplish the processing of various complicated tire patterns.
Description
The utility model relates to a kind of colored machine that mills, particularly a kind of numerical-controlled milling machine for tyre tread mould.
Chinese invention patent CN1045936A and Chinese utility model patent CN2064277U have proposed scheme with a kind of numerical-controlled milling machine for tyre tread mould respectively in nineteen ninety.The basic principle of the processing tire-mold that this scheme proposes is: the pendulum radius of milling cutter in horizontal plane equals tire-mold decorative pattern root radius, finished the Milling Process of mould decorative pattern separately around the relative motion of its centre of gyration generation by milling cutter and mould.This principle has obtained widely using manually milling Hua Jishang.But such scheme is used numerical control that this principle proposes and is milled colored machine and can only process open decorative pattern, can not process the enclosed type decorative pattern continuously, because enclosed type tyre tread forms the groove of sealing one by one on its mould, will be the metal mill off in the groove, (diameter in hole is greater than end mill diameters must to beat fabrication hole earlier in each enclosed type decorative pattern, the degree of depth in hole equals pattern depth), change slotting cutter then and mill decorative pattern.After a decorative pattern had milled, milling cutter entered in another adjacent fabrication hole again and continues milling along the axial back of Z withdrawing, up to whole decorative pattern millings are finished.In above-mentioned process, make fabrication hole and milling cutter continuously and belong to " control of some position " from the process that a decorative pattern jumps to another decorative pattern, need to finish jointly by two gyroaxises and a linear axis, the decorative pattern milling process is finished by two gyroaxis interlocks.So just need three reference axis.Obviously, the two-axis numerical control that such scheme proposes mills colored machine, can not finish above-mentioned process automatically continuously, so never obtain practical application.
The numerical control of above-mentioned patent disclosure is milled colored machine and is comprised two revolution reference axis that link mutually and drive system separately.The X-axis drive unit: have one, an end of axle is connected with worm gear one, and worm gear one is connected with handwheel with servomotor one, and the other end of axle is connected with floral disc, and clamping has tire-mold on the floral disc; Y-axis drive unit a: fanning strip is arranged, on fanning strip, be fixed with the milling cutter power set, the milling cutter power set have a motor, motor is connected with mill principal axis by belt, belt pulley, drives mill principal axis and rotates, and the cylindrical of the arcwall face of fanning strip has teeth, one servomotor is arranged, servomotor is connected with a pinion by worm gear two, the teeth engagement of pinion and fanning strip, and X-axis drive unit and Y-axis drive unit are installed on the same chassis simultaneously.Each servomotor that mills Hua Jizhong is connected with master controller by driver.Colored machine is milled in this numerical control can not be reciprocating in Z-direction, so when the processing tire-mold, can only process the decorative pattern of open shape continuously, can not process the decorative pattern of enclosed shape continuously.
The purpose of this utility model provides a kind of numerical-controlled milling machine for tyre tread mould that can process the enclosed shape decorative pattern continuously.
The purpose of this utility model is achieved in that and is fixed with the Z axial brake device on fanning strip.
The Z axial brake device has coattail board, is connected with coattail board on the following coattail board, connects the milling cutter power set on the last coattail board, and following coattail board underrun nut is connected with screw mandrel, and screw mandrel is connected with Z axle servomotor by the commutating tooth wheel set.
In the such scheme, owing to increased Z axle feeding control, make milling cutter or drill bit do straight reciprocating motion along its axis direction, process the decorative pattern of a sealing when milling cutter after, in the decorative pattern of a sealing, jump out, automatically enter in the decorative pattern of another enclosed shape and process, this mills colored machine can also process open decorative pattern simultaneously, has reached the purpose of this utility model.This mills colored machine has increased a Z axle feed function on original basis, can process the enclosed shape decorative pattern continuously under programme-control, not only can process the two half module tools that cross-ply is used, and can also process the activating mold that radial is used, and has improved production efficiency.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is a structure chart of the present utility model.
Embodiment: three numerical control reference axis are respectively:
X-axis is rotating shaft.Drive axle 3 rotations by servomotor 1 (or stepper motor) by worm gear 1, this left end of 3 is installed a floral disc 4 and is used for clamping tire-mold 5, and mould 5 to be processed just under the drive of servomotor 1, is turned round around axle 3 by programme-control.
Y-axis is gyroaxis.It makes the milling cutter axis is the center of circle with the O point, is radius (this radius equals tire-mold decorative pattern root radius) revolution with R.Its drive path is: servomotor 26 drives fanning strip 9 around O point rotating shaft revolution by worm gear 27, pinion 8, also turns round around the rotating shaft of O point and drive the main shaft 14 that is installed on the fanning strip.
The Z axle is linear axis.It makes milling cutter or drill bit along its axis direction feed and withdrawing.Its drive path is: servomotor 3 10 turns to 90 degree to drive screw mandrel 12 rotations by commutating tooth wheel set 11, and screw mandrel 12 is gone up coattail board 13 by the nut drive and made straight line fortune; Moving, make the main shaft 14 and the main shaft power device thereof that are fixed on the coattail board reciprocating along the Z axle.
In above-mentioned three axes, the interlock of X-axis and Y-axis realizes the Milling Process of mould decorative pattern, the Z axle needn't with preceding two-axle interlocking, only when beating fabrication hole or milling cutter realization feed and withdrawing when a decorative pattern that mills jumps to another adjacent decorative pattern to be milled.As seen, this three-dimensional numerical control mould mills colored machine in fact only needs " diaxon half " control function just passable.
