Abstract
A new fixture which is capable of holding an HSA throughout all processes is invented so that Quasi-Static Test can be done before swaging. Handling operations are reduced and rework is made much easier. The invention further provides a process for testing the HSA by means of the fixture.
Claims5
A universal fixture for an HSA Assembly comprises a platform made of stainless steal, on which provided are an alignment pin holder for holing an alignment pin for fixing all HGAs, a wedge holder, a set of wedge plates fixed separately and rotationally in said wedge holder for holding said respective HGAs, a datum pin for fitting to a bearing of an actuator, an alignment datum pin for limiting stroke of said actuator, and an AFA clamper for clamping respective arm fingers of said actuator.
A process for testing an HSA Assembly by means of a universal fixture according to any one of the preceding claims comprises steps:
- Auto-loading M/C and loading HGAs and an actuator;
- In-line dressing;
- ultrasonic bonding;
- in-line quasi static testing of said HGAs;
- if an HGA fails to pass the testing, it will be rejected and in-line reworked;
- in-line coating;
- ultra-violet curing;
- in-line swaging said HGAs and actuator to form an HSA;
- and
- visual checking and unloading of said HSA.
