Summary of the invention
Technical problem to be solved in the utility model is larger after the error accumulation that produces for the prior art drive disk assembly, be difficult to adapt to the shortcoming of the requirement of high accuracy printing, a kind of printing power set are provided, this printing power set can effectively reduce the error that drive disk assembly produces, and significantly promote the precision of transmission.The technical scheme that adopts is as follows:
A kind of printing power set, comprise roller driving mechanism and axial regulating mechanism, described roller driving mechanism is installed on the axial regulating mechanism, described roller driving mechanism comprises servomotor, electronical line shaft, cone blocking, it is characterized in that: described electronical line shaft rear end connects the output shaft of servomotor, and described cone blocking is fixed on the electronical line shaft front end.Because output shaft and the electronical line shaft of servomotor are in straight line substantially, so the error of transmission is little, the accumulation of error of having avoided gear drive and too much gear unit to produce, the accuracy of transmission has obtained significantly promoting.
More excellent scheme, described roller driving mechanism also comprises sliding sleeve, positioning sleeve, and described sliding sleeve slidably passes positioning sleeve, and described electronical line shaft can pass sliding sleeve relative to what sliding sleeve rotated.Before the work, positioning sleeve is installed on the printing wallboard.Because electronical line shaft can rotate relative to sliding sleeve, so large rocking can not occur in the cone blocking of servomotor electronical line shaft front end when driving the electronical line shaft rotation, affects roller and work.Because but sliding sleeve relative positioning cover rotates, so axial regulating mechanism is when driving the roller driving mechanism along the axially-movable of electronical line shaft, and the motion of electronical line shaft is more steady.
More excellent scheme, described roller driving mechanism also comprises flexible coupling, described electronical line shaft rear end connects the output shaft of servomotor by flexible coupling.Can effectively eliminate like this error between the output shaft of electronical line shaft and servomotor.
Described axial regulating mechanism comprises support, moves back and forth mechanism, slidably fixed mount, at least one slide rail, described slide rail is fixed on the support end face, described slidably fixed mount slidably is installed on the described slide rail, the described mechanism that moves back and forth is fixed on the support, and the motion end that moves back and forth mechanism connects slidably fixed mount.Before the work, first described support is fixed on the printing wallboard on, and so that the axis of described slide rail and described electronical line shaft be parallel to each other.
In order to limit the slidably distance of fixed mount motion, described slide rail is provided with limited block.
A kind of scheme, the described mechanism that moves back and forth is hydraulic cylinder, the motion end that moves back and forth mechanism is the axis of the piston of hydraulic cylinder.Its shortcoming is that the action of hydraulic cylinder is slower.
Another kind of scheme, the described mechanism that moves back and forth is feed screw nut's reciprocating mechanism, and feed screw nut's reciprocating mechanism comprises motor, screw mandrel, nut, and screw mandrel connects the output shaft of motor, nut sleeve is on screw mandrel, and the motion end that moves back and forth mechanism is nut.
Better scheme, the described mechanism that moves back and forth is cylinder, the motion end that moves back and forth mechanism is the axis of the piston of cylinder.
The utility model beneficial effect against existing technologies is, owing to do not adopt gear drive, and reduced as much as possible gear unit, and adopted flexible coupling to eliminate error between the output shaft of electronical line shaft and servomotor, so the precision of transmission significantly promotes; Sliding sleeve, positioning sleeve have then effectively been eliminated rocking that electronical line shaft produces in the time of work, and make electronical line shaft more steady in the movement along its axis direction.
