The utility model content
Problem to be solved in the utility model is to provide a kind of differential driving, adopts this driving, and after can guaranteeing that electroplating activity is completed, cup-shaped workpiece or vertical section are that the complete electroless plating liquid of the workpiece lumen of H shape is residual, and production efficiency is higher, and does not have potential safety hazard.
For addressing the above problem, take following scheme:
Differential driving of the present utility model comprises vehicle frame, and this vehicle frame is the door font, and chain-wheel mechanism is all arranged on the column of its both sides, is connected with the workpiece suspension rod between two chain-wheel mechanisms.The position that is characterized in the corresponding column in crossbeam two ends of described vehicle frame is equipped with motor, and the output terminal of two motors all is connected with the chain-wheel mechanism corresponding with it, makes two motors all can control coupled chain-wheel mechanism and moves up and down along the vehicle frame column.
To be described chain-wheel mechanism be comprised of fixed chain wheels and activity chain wheel the further improvement of the utility model scheme, and fixed chain wheels is fixed on the top of vehicle frame column, and the activity chain wheel is positioned at the fixed chain wheels below, and be between movable sprocket wheel and vehicle frame column and be slidably matched.Be connected by chain between described fixed chain wheels and movable sprocket wheel, when making fixed chain wheels rotate, movable sprocket wheel can move up and down along the vehicle frame column.Described workpiece suspension rod is connected between two movable sprocket wheels.
Further improvement project of the present utility model is all to be fixed with lifting support on described two movable sprocket wheels, and two relative sides of lifting support all have hook, and the two ends of described workpiece suspension rod are hung on the hook of two lifting supports.Like this, can facilitate the installation and removal of workpiece suspension rod.
In above-mentioned three schemes, all can in the arranged outside horizontal rolling mechanism of two columns of described vehicle frame, make vehicle frame to roll along horizontal rail.Thereby make this differential driving according to actual needs, along rail moving to the optional position, conveniently to use.
Take such scheme, have the following advantages:
Because the position of the corresponding column in frame cross two ends of a kind of differential driving of the present utility model is equipped with motor, the output terminal of two motors all is connected with the chain-wheel mechanism corresponding with it, makes two motors all can control coupled chain-wheel mechanism and moves up and down along the vehicle frame column.Therefore, electroplate after completing when the workpiece that to cup-shaped workpiece or vertical section is H shape is implemented to take out operation, the first synchronization job of two motors of drive a vehicle, the rising of driving workpiece suspension rod makes workpiece break away from electroplate liquid fully; Then, two motor alternately operatings make the workpiece suspension rod successively tilt together with the workpiece that hangs on it, the electroplate liquid of workpiece both sides inner chamber can be discharged fully.Thereby guaranteed that cup-shaped workpiece or vertical section are that the workpiece lumen electroless plating liquid of H shape is residual, need not to carry out again the operation of artificial removal's electroplating residual liquid, not only improved production efficiency, and avoided potential safety hazard.
