Design and Fabrication of Arduino Controller Based Hydro Pneumatic Feed Control Drilling Machine

Abstract

This work “Design and fabrication of Arduino controller based hydro pneumatic feed control drilling machine”, the Arduino controller is used to automatically control the hydro-pneumatic cylinder that feeds the portable hand-operated electric drilling machine. Here, the workpiece to be drilled is manually clamped in a vice. Here, a portable electric drilling tool is supported longitudinally on a pivoting platform coupled to the hydro-pneumatic cylinders' piston rods. One cylinder in a hydro-pneumatic cylinder comprises oil on both sides of the piston, and the ports are connected by a polyurethane tube with a diameter of 4 millimetres. The linear scale and limit switch arrangement, which is put next to the drill spindle, can be used to set the drilling depth. The workpiece that will be drilled is secured in a vise before beginning by manually tightening the bolt. This spindle begins revolving and slips through the hydro-pneumatic cylinder when the switch is depressed. When the drill spindle reaches the drilling depth, the limit switch causes it to automatically return to the home position. The output of the Arduino controller is connected to the drilling machine on/off control and the solenoid values. The Arduino controller input receives the switches' signals. The drilling machine feed is automatically regulated with the hydro-pneumatic cylinder in our project, here, a portable hand drill is supported horizontally on a platform by a clamping attachment that is attached to the hydro-pneumatic cylinders piston rods. One cylinder of a hydro-pneumatic cylinder has oil on both sides of the piston. The PVC pipeline connects the ports on the oil cylinders. Limit switches that are located close to the drill spindle allow the drilling depth to be adjusted. This spindle begins revolving and slips through the hydro-pneumatic cylinder when the switch is depressed. When the drill spindle reaches the drilling depth, the limit switch causes it to automatically return to the home position. The solenoid valve is controlled by the Arduino, which causes the cylinder to move forward and backward. The controllers are connected to the push buttons and limit switch signals.
