Description
The present invention relates to a pneumatic control device for a vacuum adsorption workbench capable of fixing a workpiece requiring surface treatment using high-pressure air, and more particularly, The vacuum pneumatic control device of the vacuum adsorption workbench which can quickly perform the repair or replacement work by constituting the manifold which is involved in the operation of the vacuum adsorption module as a unit, .
In order to carry out the surface treatment of the workpiece such as sanding or paint, or to perform welding on a specific part of the workpiece, a device for firmly fixing the workpiece is required. For this purpose, It is a vacuum adsorption workbench equipped with many mechanisms. Generally, a vacuum adsorption workbench is provided with an adsorption pad at a site where a workpiece is placed, and the air in a space between the adsorption pad and the workpiece is forcedly exhausted by using a pump, thereby firmly fixing the workpiece to provide a stable work environment .
At this time, the surface of the workpiece adhering to the adsorption pad may be entirely flat, but in many cases, the workpiece has a constant curvature or a concave groove or protrusion partially formed on the surface thereof in many cases. Many vacuum workbenches have been proposed which can be easily applied even when the external shape of the workpiece has a certain curvature or when a specific portion of the surface of the workpiece is stepped up, and Korean Patent No. 0986597, No. 0855324 are examples of such techniques.
However, in the former case, when the worker is not an experienced worker or if the surface of the workpiece has a complicated shape, it is difficult to control the vertical height accurately and the workpiece can not be tightly restrained. In the latter case, The contact area of the rod is inclined and the frictional force generated at the area is used. Therefore, when the fixing operation is repeated, the contact area is worn out and the frictional force is gradually reduced. Thus, the industrial field to which this technology can be applied is very limited .
To this end, the present applicant has proposed Korean Patent No. 1311012 as disclosed in FIG. In this technique, a plurality of vacuum adsorption mechanisms are arranged on a workbench so that the vacuum adsorption mechanisms are individually supported according to the shape of the workpiece. When the vertical positions of the respective vacuum adsorption mechanisms are determined according to the shape of the workpiece, And each vacuum adsorption mechanism is constituted by an operating configuration for restraining the workpiece.
That is, the weight of the workpiece placed on the adsorption pad of each vacuum adsorption mechanism is primarily supported by the elastic body so that the workpiece having a certain curvature or shape is guided to maintain a stable horizontal posture, and a pressure plate So that it is possible to easily fix the workpiece having a considerable weight as well as the shape of the workpiece is very complicated.
In spite of these excellent advantages, however, this technology basically requires that each vacuum suction apparatus must continuously operate a high-pressure pump in order to fix the workpiece. Therefore, a long working time consumes a considerable amount of electric power, There was a problem that the working environment was deteriorated due to the noise generated due to the continuous operation.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the conventional art, and it is an object of the present invention to provide a work machine having a complicated shape or easy to fix a work having a considerable load, Which is capable of preventing the adverse effect of the working environment caused by the operation of the vacuum adsorption workbench.
