This drilling machine is composed of a cast iron machine body, a set of hydraulic drilling spindle, a set of clamping device, a hydraulic pump and a set of electrical control system.
The hydraulic drilling spindle is fixed on the machine body where under the workpiece clamping seat. The workpiece clamping seat is composed of a set of horn type pressing-in device and a workpiece fixture. The horn type pressing-in device is driven by hydraulic cylinder. The electrical control system includes MANUAL mode and AUTO mode.
While drilling a workpiece, in case of using conventional drilling machine, it is necessary to put A round end into half-round fixture. The operator uses one hand to operate the drilling machine. The shortcomings of such operation are the workipiece cannot be vertical. That will influence drilling accuracy. Furthermore, it is necessary to clean working table every after completing one workpiece. That makes the operation speed slow and time-consuming. Conversely, this hydraulic drilling machine is suitable for various drilling operations, such as pepper mill and its lid, curtain support, single hole or multiple hole drilling operation, etc. The operator just put B end inside the fixture and push down AUTO mode button. The horn type pressing-in device will press on A end. Meanwhile, the hydraulic drilling spindle will lift up to drill. After the drilling travel reaches a certain depth, the drilling spindle will move downward and pressing-in device will return to its original position. The drilling operation is complete and it is able to take out the finished workpiece. Easy to make fixtures, drilling operation is quick and safe, working tale is clean and no chips are its advantages.
