AUTO INDEXING GEAR CUTTING ATTACHMENT FOR PNEUMATIC SHAPING MACHINE

SYNOPSIS

A shaper is used to machine a single job by using a single point cutting tool and hence it can not be used for high production rates. This project intends to use pneumatic shaper for high production of automatic gear cutting with auto indexing work piece. A small ratchet gear structure has been thus devised to demonstrate the gear cutting attachment in shaping machines.
The pneumatic source of power with control accessories is used to drive the ram or the cylinder piston to obtain the forward and return strokes. By this arrangement the forward/reverse stroke of the pneumatic cylinder is adjustable type when compared with the conventional machines. We desired a shaping machine which will automatically index the job and gives automatic tool feed to the pneumatic cylinder.

INTRODUCTION
This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased.

Degrees of automation are of two types, viz.

  1. Full automation.
  2. Semi automation.

In semi automation a combination of manual effort and mechanical power is required whereas in full automation human participation is very negligible.

WORKING PRINCIPLE

  1. The compressed air from the compressor reaches the solenoid valve. The solenoid valve changes the direction of flow according to the signals from the timing device.
