The maintenance and release work is the most essential act to carry out the machining to keep the work in the correct position. To release the job quickly and keep the job rigidly. To avoid vibration of the work while performing the machining We are using mechanical devices of work clamping. In this project we are dealing with the pneumatic rod used in the drilling machine. In the pneumatic type one end of the piston rod is connected to the movable jaw and the piston slides in the cylinder. Here the air drives the movement of the piston, this in turn drives the movable jaw. Here the main movement is only an alternative movement. The tire is that branch of technology, which deals with the study and application of the use of pressurized air to affect the mechanical movement. "Pneumos" stands for "Air" and "Tics" means "Technology Pneumatics is using the air to push or throw things or suck them in. Pistons and tubes are light and powerful, lighter than equivalent engines, however, the compressor is In itself an engine and is heavy.The air compressor keeps the air storage tanks filled and the storage tanks provide the reserve air to quickly fill the actuators or pistons Storage tanks are at least twice the pressure of The actuators, so that a storage air tank will quickly fill an actuator of the same size, but after that the air compressor can not replenish the used air very quickly.
It adds about half a cubic foot of air per minute, depending on the Pressure already in the system which is striving to put more air in. Less air is moved near full pressure (.24cfm) and more to zero pressure (.79 Cfm), so in an entire 2-minute game expect the air compressor to add ~ .8 cubic feet of air. Plan a test while observing the main high pressure gauge to see how low it is during what you expect to be a normal operation.
