AI Technical Summary
Traditional dripping water testing fixtures require multiple angles due to differences in manufacturers and sensor installation angles, increasing production costs.
Design an adjustable oxygen sensor drip test fixture. Through the combination of base, swing arm and fixing plate, the angle can be adjusted from 0-90° to meet the testing needs of different manufacturers and sensors.
There is no need to manufacture special tooling for each angle, which reduces production costs and improves the flexibility and efficiency of testing.

Abstract
Claims
1. An angle-adjustable oxygen sensor drip test fixture, characterized by: The device includes a base, a swing arm, and a fixing plate. The base has mounting holes and positioning holes; the positioning holes are arc-shaped, with the mounting holes serving as the center of the arc. Angle markings from 0 to 90° are provided on the outer side of the arc. A rotating shaft is located at the rear of the swing arm, and a fixing plate is located at the front end of the swing arm. The rotating shaft is located on the bottom surface of the swing arm, and the fixing plate is located on the top surface of the swing arm. The rotating shaft is positioned within the mounting holes. The swing arm is rotatably mounted on the base with the mounting holes as its center. The swing arm is located above the positioning holes and angle markings, with its front end extending to the outside of the angle markings. A test hole is provided on the fixing plate, the size of which matches the size of the oxygen sensor, serving as a testing station. The mounting angle of the oxygen sensor can be adjusted by rotating the swing arm.
2. The angle adjustable oxygen sensor drip test fixture of claim 1, wherein: The mounting plate has mounting holes located above the test hole, with the lower end of the mounting holes communicating with the test hole. Screws are installed inside the mounting holes to fix the oxygen sensor inside the test hole.
3. The angle adjustable oxygen sensor drip test fixture of claim 1, wherein: The swing arm is equipped with a fixed angle hole located above the arc-shaped structure. A bolt is installed in the fixed angle hole, and the swing arm is fixed at the required angle by the bolt and the nut set on the bottom surface of the base.
4. The angle-adjustable oxygen sensor dripping test fixture according to claim 1, characterized in that: A ball bearing is installed in the mounting hole, and the shaft passes through the ball bearing.
