[0025] See Figures 1 - 4 As shown, in an embodiment of the present utility model, a thread testing mechanism is proposed, which is used to quickly test whether the thread structure of the workpiece 100 to be detected is qualified. Whether the thread is qualified is generally tested by a ring gauge 200. Specifically, it includes a base 1 and a sliding guide rail 2 spaced on the base 1. A sliding seat 3 is slidably installed on the sliding guide rail 2. A first jaw 4 is provided on the sliding seat 3. The first jaw 4 is used to clamp the workpiece 100 to be detected. The workpiece 100 to be detected is clamped through the first jaw 4, and different types of workpieces 100 to be detected can be replaced. And it can be moved with the sliding seat 3 to meet the position sliding during the thread fitting process. At the same time, a fixed seat 5 is provided on the base 1. A rotary cylinder 6 is installed on the fixed seat 5. A second jaw 7 is installed on the rotary cylinder 6. The second jaw 7 is used to clamp the ring gauge 200 for detecting the thread of the workpiece 100 to be detected. The ring gauge 200 is clamped through the second jaw 7, and when detecting the threads on different types of workpieces 100 to be detected, the ring gauge 200 can be replaced. And a servo motor 8 is connected to the rotary cylinder 6.

[0026] Specifically, during the detection process, the servo motor 8 and the rotary cylinder 6 drive the second jaw 7 to rotate, so that the ring gauge 200 rotates and cooperates with the thread of the workpiece 100 to be detected for testing. During the testing process, the workpiece 100 to be detected, the first jaw 4 and the sliding seat 3 slide relative to the sliding guide rail 2 to meet the testing process.

A first step structure 42 is provided on the first jaw teeth 41. The workpiece 100 to be detected is limited through the first step structure 42. And the three first jaw teeth 41 slide on the first jaw 4 to adapt to the size of the workpiece 100 to be detected for clamping.

[0029] At the same time, the second jaw 7 includes three second jaw teeth 71 evenly distributed along the circumferential direction. A plurality of second step structures 72 with diameters increasing sequentially from inside to outside are provided on the second jaw teeth 71. Similarly, the three second jaw teeth 71 slide on the second jaw 7 to adjust and adapt to the diameter of the ring gauge 200 for clamping. At the same time, the plurality of second step structures 72 can adapt to the clamping of more ring gauges 200 with different diameters.
