Abstract

As disc drives become more compact for commercial acceptance and volumes increase, subsequent manufacturing equipment must be downsized and be ergonomically acceptable. In addition, as disc drives store more and more information on each disk, the requirement for the tooling not to subtly influence the file becomes critical. Often times a simple spring-loaded clamp is acceptable. However, in cases where higher clamp forces are a requirement, they are unacceptable for high production rates. The problem becomes how to design a clamp that can be actuated easily with an operator's finger tips, can withstand high opposite forces from the device being clamped, and not apply a great force to the clamped member in the normal state.

Ergonomic Non-Influencing Clamp

      As disc drives become more compact for commercial
acceptance and volumes increase, subsequent manufacturing equipment
must be downsized and be ergonomically acceptable.  In addition, as
disc drives store more and more information on each disk, the
requirement for the tooling not to subtly influence the file becomes
critical.  Often times a simple spring-loaded clamp is acceptable.
However, in cases where higher clamp forces are a requirement, they
are unacceptable for high production rates.  The problem becomes how
to design a clamp that can be actuated easily with an operator's
finger tips, can withstand high opposite forces from the device being
clamped, and not apply a great force to the clamped member in the
normal state.

      A unique clamp was developed (see Fig. 1) which is actuated by
first pressing button 1 with a low force.  This button has two
mechanical functions; it releases pressure and retracts the clamp so
that the clamp can be pivoted in/out of the clamping area.  Secondly,
clamp rotation is actuated by an adjacent finger tip by pushing on a
lever 2 which is connected to the main body of the clamp.

      A low force acting on button 1 (see Fig. 2) compresses spring
2, allowing spherical bearing 3 to move horizontally releasing clamp
force 4 and retracting clamp.  Lever 5 connected to main body of
clamp 6 provides rotation within recess area of flange 7.
