1. FABRICATION OF AUTOMATIC CLAMPING, INDEXING AND
HYDRO PNEUMATIC FEED CONTROL OFDRILLING
ATTACHMENT
OBJECTIVE;
· To develop industrial automation and assist with CIM
environment.
· To promote the unmanned industry.
· To promote the unmanned industry.
Project Background;
In the present global rationalization and competitive world most
of the industries set up unmanned industry in order to eliminate
labour cost and to increase productivity.
ABSTRACT;
In our project “FABRICATION OF AUTOMATIC CLAMPING, INDEXING
AND HYDRO PNEUMATIC FEED CONTROL OFDRILLING ATTACHMENT” , the
drilling machine feed is controlled automatically with the hydro-pneumatic
cylinder and the job is clamped by the pneumatic cylinder.
2. Here, a portable hand-drilling machine is held in horizontal on a
platform with a clamping attachment, which is fitted to the piston rods of the
hydro-pneumatic cylinders. In hydro-pneumatic cylinder, one cylinder is
filled with the oil on both sides of piston. This oil cylinder ports are
connected through the pvc pipeline..
The drilling depth can be set with the arrangement of linear scale and
limit switch and is placed adjacent to the drill spindle. When the switch is
pressed, this spindle starts rotating and slides by the hydro-pneumatic
cylinder. The drill spindle automatically returns to the home position by the
limit switch when it reaches the drilling depth. After completing the first
drill on the job , the work piece is indexed for second drilling operation by
the another air cylinder. Again the same drilling process is made for second
drill.
The drilling machine ON/OFF control and the solenoid values are
connected to the control system.. The signals from the switches are fed to
the input of the electronic control
ADVANTAGES;
· This system is used to develop industrial automation
and assist with CIM environment.
3. · It promote the unmanned industry.
· Reduces waste motions which cause fatigues to
worker.
· It reduces labour cost
