ABSTRACTS
➢The main objective of our project is to perform various machining operations. In the
manufacturing area this paper need one device for work and tool holding. For work
holding this paper need vice to keep the work piece stationary while machining. Here
the vice is adjusted by using the pneumatically operated jack. From the compressor the
air is supplied to the jack.
➢ Due this pneumatic force the jack is adjusted (vertically or horizontally) correspondingly
the vice is adjusted. Work holding and releasing is the most essential act to carry out
using “auto feed mechanisms” in work holding device with the of help of pneumatic
system .
➢This project using two mechanisms one mechanisms is used to hold work piece and
another one is to feed the work piece into holding device in automatically. A
pneumatic machine can be thought of as a large flexible mechanical structure that is
moved by some sort of control system. The control system takes its input from a human
operator and translates this command into the motion of actuators, which move the
mechanical structure.
➢The high performance and highly powerful, pneumatic machine vice together with the
capacity for high volumes are suited for holding heavy objects. Generally, pneumatic
cylinder operations are based on pneumatic pump operation. Air is pumping to the
pneumatic cylinder by using pneumatic pump system.
OBJECTIVES
➢The main objective of project is to improve version of a mini
pneumatic jack. This will be more efficient for the user. This
machine is pneumatic powered which has low co-efficient of
friction.
➢A pneumatic cylinder erected provides power to lift up the
Jacky. This is a pneumatic powered machine and requires
no other means of power to operate.
➢ The advantage of a mechanical jack is the ratio of the load
applied to the effort applied.
➢ The height of the jack is adjusted by turning a lead screw and
this adjustment can be done either manually or by integrating
an electric motor

INTRODUCTION
➢It means “Air” and “Tics” means “Technology Pneumatics is using air to push/pull things or suck
them up.
➢The pistons and tubing are light and powerful, lighter than equivalent motors; however, the
compressor is itself a motor and is heavy.
➢ Once the big decision to add the compressor is made, adding extra pistons is much easier and
lighter than adding extra motors (and gearing).
➢The air compressor keeps 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 one tank of storage air will quickly fill
an Pneumatics is that branch of technology, It adds roughly half a cubic foot of air per
minute depending on the pressure already in the system that it’s striving to shove more air into.
COMPONENTS USED
➢Double acting cylinder
➢Solenoid valve
➢Compressor
➢Air hose
➢Mild steel plates
CONSTRUCTION
➢ A pneumatic system consists of a group of pneumatic components connected together so that a
signal (compressed air) is passed through the system to make something happen at the output.
These groups of components can be divided into five categories according to their function in
the pneumatic circuit as follows:
➢ Supply elements: these elements are the sources of power that drives the system which are the
compressors.
➢ Input elements: these elements are used to send signals to the final control elements and come in
two forms; either as components that is actuated by the operator like push buttons or sensors that
determine the status of the power elements such as limit switches and proximity sensors.
➢ Processing elements: these elements may perform operations on the input signals before
sending the signal to the final control elements such as non-return valves, directional control
valves and presser control valves.
➢ Final control elements: to control the motion of actuators such as directional control valves.
➢ Power elements (actuators): these are the outputs of the pneumatic system which use the stored
potential energy to perform a certain task such as pneumatic cylinders and motors.
WORKING PRINCIPLES
➢ In pneumatic type vice one end of piston rod is connected to the movable jaw and the
piston slides in the cylinder. Here the air actuates the movement of piston; this in turn
actuates the movable jaw. Here the principle movement is only a reciprocating
movement.
➢ A vice is a mechanical screw apparatus used for holding or clamping a work piece to
allow work to be performed on it with tools such as saws, planes, drills, mills,
screwdrivers, sandpaper, etc.
➢ A pneumatic system is controlled through manual or automatic process. In this
Automatic pneumatic vice project for metal working is provided with widely and quick
movable clamping jaw and fixed jaw where the vertical clamping surface of the fixed
jaw and the horizontal surface of the fastening plane for the working piece confirm an
accurate and unchangeable.
➢ Using automatically operated pneumatic vice will help you to get the work down easily
and save energy.
➢A pneumatic machine can be thought of as a large flexible mechanical structure
that is moved by some sort of control system. The control system takes its input
from a human operator and translates this command into the motion of
actuators, which move the mechanical structure.
➢The high performance and highly powerful, Pneumatic machine vice together
with the capacity for high volumes are suited for Holding Heavy Objects.
➢The automatic pneumatic jack for light vehicle garages has been developed to
cater the needs of small and medium automobile garages. In most of the
garages the vehicles are lifted by using screw jack. This needs high man
power and skilled labours.
➢In order to avoid all such disadvantages, this automatic pneumatic jack has been
designed in such a way that it can be used to lift the vehicle very smoothly
without any impact force.
➢The operation is made simple so that even a layman person can handle it by
just pressing the button.

ADVANTAGES
1. Idle time of the machine is reduced.
2. When compared with the mechanical vices, it
consumes less time for clamping and unclamping the
job.
3. It reduces the manual labour
4. Hence, production rate is higher
5. In this mechanism there is no backlash.
DISADVANTAGES
1. Initial higher cost.
2. May be a choice of air leakage
3. Cylinder stroke length is constant
APPLICATIONS
1. To hold the job rigidly while machining.
2. For quick clamping and unclamping of the job
CONCLUSION
➢Safety rules help to keep us safe. They highlight dangers and this helps to
prevent accidents. When we are using pneumatics, we must follow these
rules.
1. Never blow compressed air at anyone, not even yourself.
2. Never let compressed air come into contact with your skin, as this can be very
dangerous.
3. Always wear safety goggles when you are connecting and operating circuits.
4. Check that all airlines are connected before turning on the main air supply.
5. Always turn off the main air supply before changing a circuit.
6. Keep your hands away from moving parts.
7. Avoid having airlines trailing across the floor or where someone could trip or
become entangled.
