Work holding devices used in shaper

The workpieces can be clamped on a shaper table in different ways.

1. Directly clamp on the table

2. Vice

3. Angle Plate

4. V-Block

5. Index centre

Direct Clamping

The workpieces can be clamped directly on the surface of the table by using following devices and illustrated in figure.

1.T-bolt and nut/T-nut and bolt

2. Toe dog and stop pin

3. Strip and stop pin

 

Vice

This is the most generally used method for holding workpieces  in shaper but limited to small width jobs which can be accommodated between the jaws. Parallel plates are used to support small thickness workpieces.

Angle Plate

For machining a surface perpendicular to another surface, angle plates are used for clamping.

V-block

For machining on workpieces with round sections V-blocks are used for clamping.

Shaper Centre

This is a special attachment particularly used to machine equally spaced grooves or splines on the periphery of a round surface.
