Abstract
An apparatus for friction welding a workpiece to a substrate, comprising an actuator producing a linear oscillating motion, a platform for supporting the workpiece, and a slide mechanism between the actuator and the platform. The slide mechanism converts the linear oscillating motion of the actuator into an arcuate oscillating motion of the platform. The slide could comprise a base and a guide engaging the platform.
Claims20
An apparatus for friction welding a workpiece to a substrate, comprising:
- an actuator producing a linear oscillating motion;
- a platform for supporting the workpiece;
- and
- a slide mechanism between said actuator and said platform, said slide mechanism converting said linear oscillating motion of said actuator into an arcuate oscillating motion of said platform;
- whereby the platform can move the workpiece in said arcuate oscillating motion against the substrate.
A slide mechanism for a friction welding apparatus having an actuator and a platform for supporting a workpiece, the slide mechanism comprising:
- a base;
- and
- a guide engaging the platform and converting a linear oscillating motion of the actuator into an arcuate oscillating motion of the platform.
A linear friction welding machine having an actuator, a platform and a slide mechanism, wherein the improvement comprises said slide mechanism converting a linear oscillating motion of said actuator into an arcuate oscillating motion of said platform.
A method of friction welding a curved workpiece, having a leading edge and a trailing edge, to a substrate, comprising the steps of:
- providing an actuator which generates a linear oscillating motion;
- converting said linear oscillating motion of said actuator into an arcuate oscillating motion of said workpiece;
- and
- contacting said substrate with said workpiece with a force sufficient to bond said workpiece to said substrate.
