Abstract
A mounting fixture for a vibration table which can compensate for work pieces that have different dimensions. The fixture includes a support block which has an elongated slot that allows the fixture to be adapted for work pieces of different lengths and widths, and a pair of clamping blocks which have corresponding chuck and groove features that can compensate for different work piece thicknesses.
Claims7
A clamping fixture that can clamp a work piece to a table, comprising:
- a base clamping block which has a first groove and a second groove located on a top side of said base clamping block, said first groove having a first depth greater than a second depth of said second groove;
- a top clamping block which has a first clamping member and a second clamping member extending from a bottom side of said top clamping block, said second clamping member being longer than said first clamping member, said top clamping block being located relative to said base clamping block such that one of said clamping members is adjacent to one of said grooves to create an opening which can receive the work piece;
- and,
- a clamping device that clamps said clamping member onto the work piece.

A clamping fixture that can clamp a work piece to a table, comprising:
- a base clamping block which has a first groove and a second groove located on a top side of said base clamping block, said first groove having a first depth greater than a second depth of said second groove;
- a top clamping block which has a first clamping member and a second clamping member extending from a bottom side of said top clamping block, said top clamping block further includes a bore and is constructed so that said second clamping member is longer than said first clamping member, said top clamping block being located relative to said base clamping block such that one of said clamping members is adjacent to one of said grooves to create an opening which can receive the work piece;
- a toggle clamp that has a pin that is received by said bore in said top clamping block, said toggle clamp having a handle coupled to said pin by an over-center linkage mechanism and which can be moved between a first position and a second position, wherein said pin presses said chuck onto the work piece when said handle is in said second position;
- a toggle support block that supports said toggle clamp and is pivotally connected to said base clamping block;
- and,
- a support body connected to said toggle support block, said support body having an elongated slot which provides clearance for a bolt that couples said support body to the table.
