The front and rear ends of the two bidirectional threaded rods 17 are respectively rotatably connected to the corresponding fixed plates 4, and the front ends of the two bidirectional threaded rods 17 respectively rotatably pass through the front surface of the corresponding fixed plates 4. Among them, the front surfaces of the two front fixing plates 4 are fixedly connected with L-shaped fixing plates 3.

[0019] Furthermore, servo motors 2 are fixedly installed on the upper surfaces of the two L-shaped fixing plates 3, and the output ends of the two servo motors 2 are fixedly installed together with the corresponding bidirectional threaded rods 17. The outer walls of the two bidirectional threaded rods 17 are threaded with two movable sleeves 18.

[0020] Furthermore, two protective boxes 21 are provided on the upper surface of the support base plate 1. Connecting plates 19 are fixedly connected to the left and right sides of the two protective boxes 21. The ends of the two connecting plates 19 away from the protective boxes 21 are respectively fixedly connected to the corresponding movable sleeves 18.

[0021] Furthermore, a first slider 16 is fixedly connected to the lower surface of each of the two protective boxes 21, and the lower ends of the two first sliders 16 are slidably connected to the second slide groove 15. A motor is fixedly installed inside each of the two protective boxes 21, and a connecting shaft 13 is fixedly connected to the output end of each of the two motors.

[0022] Furthermore, the upper ends of the two connecting shafts 13 respectively rotate through the upper surface of the corresponding protective box 21 and extend out of the inner wall of the rectangular groove 7; Among them, the outer walls of the two connecting shafts 13 are fixedly sleeved with bearings 23, and the outer walls of the two bearings 23 are fixedly sleeved with mounting sleeves 22.

[0026] Furthermore, when using the chain production strength testing mechanism, the staff first take out the chain to be tested and attach the chain to the two sprockets 12; Then, two servo motors 2 are started. The two servo motors 2 rotate in the same direction. The two servo motors 2 drive the two bidirectional threaded rods 17 to rotate. The two bidirectional threaded rods 17 drive the two movable sleeves 18 connected to them to move to opposite positions. Among them, the four movable sleeves 18 drive the two protective boxes 21 to move to opposite positions through the four connecting plates 19.

When it is necessary to test the chain rotation, one of the two motors is started first. The motor drives the sprocket 12 connected to it as the driving wheel, and the other sprocket 12 as the driven wheel, thereby driving the chain to rotate rapidly, and then the chain rotation intensity is tested. When it is necessary to test the tensile strength of the chain, firstly, two servo motors 2 are started. The two servo motors 2 rotate in the same direction. The two servo motors 2 drive the two bidirectional threaded rods 17 to rotate. The two bidirectional threaded rods 17 drive the two movable sleeves 18 connected to them to move to opposite positions. Among them, the four movable sleeves 18 drive the two protective boxes 21 to move to opposite positions through the four connecting plates 19, the two protective boxes 21 drive the two connecting shafts 13 to move to opposite positions, and then drive the two sprockets 12 to move to opposite positions, thereby tightening the chain. Among them, the opposing surfaces of the two mounting sleeves 22 will push the moving rod 11 connected to them to move to the opposing position, and then push the two springs 10 to compress through the two circular sleeves 24, and then apply the force to the two S-shaped pressure sensors 9, thereby detecting the tension of the chain and determining the tensile strength of the chain. The strength testing component not only detects chain rotation but also chain tensile strength. The testing process is simple and convenient, thereby improving the reliability of chain testing and enhancing the practicality of strength testing mechanisms for chain production.

[0027] Structural Description: S-type pressure sensor 9: The S-type pressure sensor model is CL-YB-68. When an external force is applied to the elastic body (elastic element, sensitive beam) of the S-type pressure sensor, the elastic body will undergo elastic deformation. This deformation will cause the resistance strain gauge (conversion element) attached to the surface of the elastic body to also undergo corresponding deformation. As the resistance strain gauge deforms, its resistance value will change (increase or decrease). Then, through the corresponding measurement circuit, this resistance change is converted into an electrical signal (voltage or current), thereby completing the process of converting external force into an electrical signal.

[0028] Bearing 23: Bearing 23 plays an auxiliary role in the rotation of connecting shaft 13.

[0029] Sprockets 12: Sprockets 12 are used to fix the chain, and their shape and size can be determined according to the actual situation.

[0030] Servo motor 2: Servo motor 2 is used to drive the bidirectional threaded rod 17 to rotate.

[0031] Second slide 15: The second slide 15 plays an auxiliary role in the movement of the first slider 16.

[0032] Second slider 20: The second slider 20 plays an auxiliary role in the movement of the mounting sleeve 22.

[0033] First slide 14: First slide 14 plays an auxiliary role in the movement of second slider 20.

[0034] Connecting shaft 13: Connecting shaft 13 is used to drive sprocket 12 to rotate.

[0035] Concave mounting bracket 8: The concave mounting bracket 8 is used for the installation and support of the S-type pressure sensor 9.

[0036] Fixed plate 4: Fixed plate 4 provides initial support for the bidirectional threaded rod 17.

[0037] Support frame 5: Support frame 5 provides support for rectangular plate 6.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
