It is miscellaneous, and the hydraulic cylinder sealing performance relative reduction in rotation, influence service life.
Utility model content
The purpose of this utility model is to provide a kind of steel strip coiling machine, to solve to drive the volume of coiling machine using hydraulic cylinder
Axis it is mobile and caused by pipeline difficult arrangement it is complicated the problem of.
To realize the utility model aim, the technical solution that uses for：On a kind of steel strip coiling machine, including rack, rack
Spool and driving spool axial movement spool moving mechanism；One end of spool is equipped with external screw thread and thread fitting has nut,
Nut rotation is supported in rack, and one end end face of nut towards spool moving mechanism offers two circumferentially uniformly distributed jacks；
Spool moving mechanism includes the spline housing of the splined shaft being coaxially disposed with spool and splined shaft axial sliding fit, driving spline
The cylinder of axis axial movement, the bearing being fixed in rack；Spline housing rotating support is connected with bearing and drives its rotation
Motor；The both ends of splined shaft are respectively provided with boss, and the end face of the boss towards nut offers two circumferentially uniformly distributed pin holes,
The latch for stretching out boss is provided with pin hole, spring is provided between latch and the bottom hole of pin hole, latch matches with jack；Flower
The end face of the boss of the key axis other end is in spherical crown shape, and is arranged with cavity outside boss, is had between boss and the inner surface of cavity
Gap, cavity are connected to the piston rod of cylinder.
Further, one end that the latch stretches out boss is in arc-shaped, and the other end is in ladder shaft-like.
Further, the pin hole is the counter sink of perforation, and the small end of counter sink is matched somebody with somebody towards nut, the hole wall screw thread of big end
Conjunction has plug screw.
Further, the spline housing is connected with motor for belt transmission.
Further, the nut by bearing rotating support in rack.
Further, the bearing is ball bearing.
The beneficial effects of the utility model are that the rotation for driving spline housing by motor rotates and then drive splined shaft, gas
Cylinder drives spline axial nut to move by cavity, the axial force that cylinder promotes only is transmitted between splined shaft and cavity, so that band
While dynamic splined shaft movement, the rotation of splined shaft is not influenced, and in this motion process, latch contact nut end face, works as rotation
During to jack, latch enters jack under spring force, and the rotary motion of splined shaft is transferred to nut, nut rotation and then
Spool movement is driven, realizes the axial movement of spool, it is not necessary to follows rotating hydraulic cylinder, avoids the pipeline cloth of complexity
It is simple and reliable if making spool realize effective axial movement by the driving of thread fitting.
