Summary of the invention
The purpose of this utility model is for existing problem, has proposed the high centre driving device of control accuracy in a kind of large stereo engraving machine.
The purpose of this utility model can realize by following technical proposal: a kind of centre driving device of large stereo engraving machine, has guide rail on the engraving machine, top be connected on the guide rail and can be along the guide rail translation, it is characterized in that, described top pedestal and the push rod that is used for ejecting workpiece that is connected on the pedestal of comprising, described pedestal is connected on the guide rail and is provided with the actuator that can drive the pedestal translation between pedestal and guide rail.
A top end be used to withstanding workpiece, translation can push workpiece is fixed with rotating disk mutually inwards, and top outside translation can be taken out workpiece.Push rod is connected on the pedestal, and actuator drives pedestal along the guide rail translation.
In the centre driving device of above-mentioned large stereo engraving machine, described pedestal inside is cavity, and above-mentioned actuator is positioned at pedestal.Actuator is positioned at pedestal, and actuator drives pedestal together along the guide rail translation.
In the centre driving device of above-mentioned large stereo engraving machine, described actuator comprises the motor that is fixed on the pedestal and is connected in the tooth bar at guide rail place, be connected with travelling gear between motor and the tooth bar, the engagement of driving cog wheel and rack and travelling gear link to each other with machine shaft.Machine shaft rotarily drives travelling gear and rotates, the engagement of driving cog wheel and rack, and tooth bar is fixed on the guide rail of engraving machine, so travelling gear rolls simultaneously also and then translation of motor and pedestal along tooth bar.
In the centre driving device of above-mentioned large stereo engraving machine, the described pedestal outside is provided with the button that can make motor action or stop.The button control motor action, the pedestal translation; When not needing the pedestal translation, the control button disable motor.
In the centre driving device of above-mentioned large stereo engraving machine, described travelling gear quantity is at least two, the output of travelling gear and the engagement of above-mentioned tooth bar, and input and the machine shaft of travelling gear are connected.Two cooperate with upper transfer gear and can change transmission speed and transmission direction.
In the centre driving device of above-mentioned large stereo engraving machine, be evenly equipped with some locating holes along its length direction on the described guide rail, described pedestal is provided with the alignment pin that can insert any one locating hole.In the locating hole on the alignment pin insertion guide rail, pedestal and guide rail are fixed, when engraving, make pedestal keep stable, improve the accuracy of carving.
In the centre driving device of above-mentioned large stereo engraving machine, described alignment pin is screw, and alignment pin is threaded with locating hole.Screw precession locating hole forms the location; Screw out locating hole, pedestal affranchises, and again can slide along guide rail, operates more convenient quick.
Compared with prior art, this device utilizes the top translation on guide rail of motor-driven, and it is time saving and energy saving to compare manual promotion; Utilize rack-and-pinion to cooperate to realize pedestal and guide rail phase shift, control pedestal mobile accuracy is high.
