A precision machining fixture for a coupling connector and a gear
By designing precision machining fixtures for coupling connectors and gears, and utilizing support and positioning components, the coupling can be quickly assembled by a single person. This solves the problem that traditional coupling assembly requires two workers and involves high physical exertion, thus improving assembly efficiency and ease of operation.

Abstract
This invention relates to the field of coupling assembly technology, specifically a precision machining fixture for coupling connectors and gears. The fixture includes a base, a support assembly on top of the base, an internal gear sleeve on top of the support assembly, and an externally shaped gear shaft fitted inside the internal gear sleeve. A positioning assembly for centering the externally shaped gear shaft is also provided on top of the base. This precision machining fixture for coupling connectors and gears positions the internal gear sleeve using the support assembly, and then centers the externally shaped gear shaft using the positioning assembly. This completes the positioning of the hoisted externally shaped gear shaft and internal gear sleeve. Personnel use their own weight to step on a pedal, and the externally shaped gear shaft is positioned via an outward-expanding part, reducing the strain on the personnel's arms when adjusting the position and minimizing physical exertion. Personnel only need to adjust the angle using their arms.
