In above-mentioned milling attachment, be fixed with the bearing block that has through hole on it on described plate body two, above-mentioned milling cutter is fixed in tubular fixed axis, and fixed axis stretches out in the milling section of milling cutter, fixed axis is arranged in through hole and through hole is all stretched out at its two ends, and the two-port place of above-mentioned bearing block through hole has the keeper for the axial restraint fixed axis.
Milling cutter is fixed on fixed axis, under the keeper effect, fixed axis is axially fixed on bearing block.Obviously, make like this milling cutter also be axially fixed.
In above-mentioned milling attachment, be provided with bearing between described fixed axis and bearing block.Milling cutter capable of being rotates smoothly with respect to bearing block under the effect of bearing, but can not break away from from bearing block.
In above-mentioned milling attachment, described keeper is locking nut one and locking nut two, locking nut one is threaded connection at fixed axis one end, and locking nut two is by being threaded in the other end of fixed axis, and locking nut one and locking nut two branches are resisted against the two ends of fixed axis.
By locking nut one and locking nut two, milling cutter is axially fixed on fixed axis firmly.
In above-mentioned milling attachment, the quantity of described bearing is two, and the end of two bearings is mutually concordant with the bearing block two-port respectively, and above-mentioned locking nut one and locking nut two are resisted against respectively two bearing ends.
Make fixed axis to rotate with respect to bearing block more smoothly by two bearings, simultaneously, can also change separately after bearing or locking nut one, two damage, extend the service life of whole device.
In above-mentioned milling attachment, described drive mechanism is to be connected in belt wheel one on fixed axis, to be connected in belt wheel two and a Timing Belt in rotating shaft, and Timing Belt is enclosed within on above-mentioned belt wheel one and belt wheel two.
Toothed belt transmission combines with transmission, chain transmission and gear drive advantage separately.During rotation, by being meshed transferring power with tooth with the teeth groove of belt wheel.Toothed belt transmission has gearratio accurately, without slippage, can obtain constant speed ratio, stable drive, and the energy absorbing, noise is little, and gear range is large.
In above-mentioned milling attachment, described bearing block sidepiece has Timing Belt with holes, above-mentioned and passes with holes being enclosed within on described belt wheel one.
Such structure makes belt wheel one be positioned at bearing block, and the junction of Timing Belt and belt wheel one is covered, and increases transmission stability.
Compared with prior art, this milling attachment is owing to adopting toothed belt transmission, and such structure makes the milling cutter capable of being of unsettled setting enter special-shaped workpiece inside to carry out milling operation, and toothed belt transmission also makes the milling cutter rotating speed steady, and job stability is high.
Simultaneously, this device only is comprised of base plate, bearing block and milling cutter etc., and therefore, structure is also fairly simple, has higher practicality.
