ENGINEER'S VICE
Engineer's bench vices are also known asmetalworking
vices and are typicallyfabricated from iron or steel. These vicesare not
an integrated part of theworkbench, allowing them to beremoved and used
on any suitable worksurface. They are attached so that thejaws of the
vice sit above the level of thework surface, at about elbow height,
togive more purpose for working onharder materials and slightly
protrudingbeyond the edge of the bench.
COMMON FEATURES
For the
engineering bench vise, it consists of two jaws, onestationary and one
moveable. These arefitted into a frame with a screwapparatus operated by
a lever whichcontrols the moveable jaw, allowing thespace between the
jaws to be expandedor contracted to accommodate different-sized pieces
of material.
STATEMENT OF PROBLEM
A problem with known types
of vice is that the numerous component parts thereof mean that the clamp
is relatively expensive to manufacture. Furthermore, if the clamp is of
relatively complex construction it may be similarly complex to operate.
In particular, it is inconvenient to have to use both hands in order to
clamp an object in the clamp and a one-handed operation would be more
desirable. Also, vices tend to be heavy and are normally fixed to a work
surface. Research have also shown that the available bench vice are not
cost effective, hence these machine tools are not readily available to
the engineers, technicians, artisans who are greatly in need of this
machine tool for their daily work in the workshop.
Most vises in the
workshops are too big and are not amenable to small work pieces holding.
Besides, because of their sizes, their materials of construction are
big and hence cost much.
When under pressure, most vise designs
deflect creating part alignment problem requiring that lifted work
pieces be forced down with hammer
It is therefore an object of the present invention to provide a clamp which alleviates the above-described problems
OBJECTIVES OF THE STUDY
To design a bench vise.
Modify an existing bench vice for small scale workshop production.
To analyze the design structure of the bench vice.
To improve the existing design through material and size reduction
Evaluate the cost of the modified bench vice.
Alleviate the sufferings of engineers, technicians, artisans who use hand to grip object for cutting, planning, gluing etc.
