Abstract
A bond fixture including a plurality of supports mounted about a surface. At least one of the plurality of supports includes a vertical member and a hand crank operable to adjust a position of the vertical member. A first fixture is disposed at an end of the bond fixture and is movable relative to the surface. The first fixture includes a base and a support extending from the base. A second fixture includes a first member and a second member movably coupled. A fastener extending between the first member and the second member controls relative movement of the first member and the second member to define an opening there between. Each of the first member and the second member includes a plate having a heater formed therein.
Claims11
A bond fixture comprising:
- a plurality of supports mounted about a surface, wherein at least one of the plurality of supports includes a vertical member and a hand crank operable to adjust a position of the vertical member;
- a first fixture disposed at an end of the bond fixture and being movable relative to the surface, the first fixture including a base with an upper surface and a support extending vertically from the upper surface of the base at a non-perpendicular angle to the upper surface;
- one or more fasteners positionable within an opening formed in the support;
- and
- a second fixture including a first member and a second member pivotally mounted via a pin, wherein a fastener extending between the first member and the second member at an angle to the pin controls relative rotation of the first member and the second member to define an opening there between, each of the first member and the second member includes a plate having a heater formed therein.
