[0047] The working principle and usage process of the present utility model:

[0048] To ensure that the end of the anchor rod and the processing port of the three-axis thread rolling machine are on the same central axis, first place the anchor rod between the first thread rolling wheel 15, the second thread rolling wheel 19 and the third thread rolling wheel 27. Then start the first pneumatic cylinder 3, which will drive the rectangular plate 4 to move downward. As a result, the two connecting rods 5 will rotate to drive the two clamping plates 6 to move towards each other, thus achieving the purpose of clamping and positioning the anchor rod, ensuring that the anchor rod and the processing port are on the same central axis. Subsequently, start the second pneumatic cylinder 20, which will drive the third movable plate 21 and the third thread rolling wheel 27 to move leftward to fit with the anchor rod. After that, start the first motor 12, the second motor 16 and the third motor 24, which will cause the first rotating shaft 13, the second rotating shaft 17 and the third rotating shaft 25 to drive the first connecting shaft 14, the second connecting shaft 18 and the third connecting shaft 26 to rotate. As a result, the first thread rolling wheel 15, the second thread rolling wheel 19 and the third thread rolling wheel 27 will rotate, and the thread rolling of the anchor rod is completed under the cooperation of the first thread rolling wheel 15, the second thread rolling wheel 19 and the third thread rolling wheel 27.

[0049] When the three-axis thread rolling machine is idle, start the drive motor 29 at this time, which will cause the transmission shaft 30 to drive the rotating rod 31 to rotate. As a result, the rotating rod 31 rotates to drive the round shaft 32 to move downward, so that the protective cover 33 moves downward, achieving the purpose of enclosing and protecting the controller 28, avoiding damage to the controller 28 caused by humans, and thus affecting the normal use of the three-axis thread rolling machine.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
