AI Technical Summary

Technical Problem

Existing hinge testing equipment suffers from problems such as unstable fixation, difficulty in precise driving and counting, resulting in low accuracy and efficiency of test results, and failing to meet the quantitative testing needs of hinges.

Method used

A hinge opening and closing test fixture was designed, comprising a fixed base, a rotating base, a fixed fixture, a rotating fixture, a servo motor, and a worm gear reducer. The servo motor drives the rotating shaft to rotate, and combined with a counting sensor and a counter, the hinge is stably fixed and the opening and closing count is accurately achieved.

Benefits of technology

It achieves stable fixing and precise driving of hinges, ensuring the accuracy of test data and efficient automated testing, and improving the efficiency and versatility of hinge quality assessment.

Abstract

This utility model provides a hinge opening and closing test fixture. The fixture table includes a fixed base, a rotating base, a fixed fixture, and a rotating fixture. Support feet are located at the bottom and rear. The fixed base mounts the fixture table, and the fixed fixture is connected to the fixed base. Hinge fixing pieces are secured with screws through fixing holes. The rotating base is connected to the fixture table via a rotating shaft, and the rotating fixture is connected to the rotating base. A clamping groove holds the hinge rotating piece, and the groove has an elastic clamping layer to prevent loosening. The fixture table contains a switching power supply, a motion controller, a servo motor, and a worm gear reducer to drive the rotating shaft. A counting sensor under the rotating base measures the number of rotations, which is displayed on the front side of the fixture table via a counter. This fixture is securely fixed, provides accurate driving and counting, is efficient and convenient, and is suitable for testing the opening and closing performance of hinges.
