Detailed description of the invention
Embodiment: as Figure 1-4, this utility model provides the specific embodiment of a kind of medicine ring saw drive mechanism, itself and air motor 70 or similar electro-motor are in transmission connection, it comprises substrate 10, be arranged on substrate 10 side and in have the axle sleeve 20 of eccentric shaft 22, be arranged on substrate 10 opposite side and the band saw power transmission shaft 30 be in transmission connection with band saw, shift fork 40 on the substrate 10 and between eccentric shaft 22 and band saw power transmission shaft 30 is set, to be set on band saw power transmission shaft 30 and the plane thrust bearing 50 be positioned at outside shift fork 40, and to be set on band saw power transmission shaft 30 and through the lining 60 of substrate 10.Wherein air motor 70 and eccentric shaft 22 are in transmission connection, and shift fork 40 is fixed by radial tightening piece 42 and band saw power transmission shaft 30, and the rotation realizing eccentric shaft 22 thus drives the swing of shift fork 40 and drives band saw power transmission shaft 30 to rotate.Lining 60 is made for copper product.
Substrate 10 is substantially oblong-shaped, comprises and is arranged on one end and the datum hole 12 of accommodating lining 60 and several screws 14 fixed for substrate 10.Its bottom bracket axle 20 is positioned at the other end of substrate 10, and shift fork 40 is between the two ends of substrate 10, and is positioned at the side of substrate 10 near axle sleeve 20.
Axle sleeve 20 comprise eccentric shaft 22, for support eccentric shaft 22 a pair inner bearing 24, for axial restraint and lay respectively at eccentric shaft 22 two ends jump ring 26, on the spindle nose 220 of eccentric shaft 22 and and the outer bearing 28 that is in transmission connection of the breach of shift fork 40 and the corrugated gasket 29 that is arranged between outer bearing 28 and eccentric shaft 22.Shown in Fig. 5, eccentric shaft 22 comprise be positioned at one end spindle nose 220, be positioned at the other end and the driving groove 222 be in transmission connection with air motor, be connected with spindle nose 220 one and the outer shaft portion 224 be positioned at outside axle sleeve 20 and being positioned within axle sleeve 20 and a pair support portion 226 be connected with inner bearing 24.Wherein the axle center in the axle center of spindle nose 220 and outer shaft portion 224 is not on the same line, and the axle center of outer shaft portion 224 and support portion 226 is then on the same line, and at regular intervals between inner bearing 24, and carries out interval by axle sleeve therebetween.
As shown in Figure 6, band saw power transmission shaft 30 comprises and is positioned at one end and the host cavity 31 of collecting band saw, is positioned at host cavity 31 side and the through hole 32 allowing saw blade fixture to pass, is positioned at the other end and allows the keyway 34 that passes of tightening piece 42 and be positioned at keyway 34 at least side and prevent anti-loaded mounting plane 36.Wherein band saw power transmission shaft 30 is preferably two stage steps axle, and an end cross-sectional area with host cavity 31 is greater than the other end, and the cross section of host cavity 31 is roughly triangular in shape, and through hole 32 radial direction is communicated with host cavity 31.Simultaneously tightening piece 42 fixes band saw power transmission shaft 30 through keyway 34, and can effectively prevent power transmission shaft in the motion of axis and radial direction, saw blade fixture can effectively stationary annular be sawed by radial through hole 32.
The output shaft of air motor 70 transmits power to eccentric shaft 22, thus drive the inner bearing 24 on eccentric shaft 22 both to rotate around outer bearing 28 axle, again around eccentric shaft 22 axis rotation, thus drive shift fork 40 to swing, and the swing of shift fork 40 drive band saw power transmission shaft 30 to swing.
This utility model realizes turning to swing by eccentric shaft thus, and utilize plane thrust bearing to prevent band saw from deflecting, accurate transmission is realized at the duplex bearing by eccentric shaft with a determining deviation side by side, solve eccentric shaft in operation process and the problem that deflects in operation process of band saw, guarantee that work accurately and reliably, reduce user and use inconvenience, structure is simple, transmission is accurate, modularized design.
