[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] See also Figure 1-3 A chain outer width detection mechanism comprises an L-shaped plate 1, an electric telescopic rod 2 installed on the L-shaped plate 1, and a detection mechanism 3 installed on the electric telescopic rod 2. The cooperation between the L-shaped plate 1 and the electric telescopic rod 2 facilitates the installation of the detection mechanism 3. The detection mechanism 3 comprises a detection seat 4 fixedly connected to the electric telescopic rod 2. A groove is provided on the outer wall of the bottom of the detection seat 4, and the inner walls on both sides of the groove are rotatably connected with the same bidirectional screw 5. The cooperation between the bidirectional screws 5 in the detection seat 4 facilitates the direct driving of two drive components 7 to move toward or away from each other. The inner walls on both sides of the groove are slidably connected with the drive components 7 screwed on the bidirectional screw 5, and contact components 12 are installed on both drive components 7. When the drive components 7 move toward each other, it is convenient to crimp the chain through the contact components 12.

[0031] Reference Figure 2 The driving assembly 7 includes a driving seat 9 slidably connected to the inner wall of the groove, and a mounting plate 10 is fixedly connected to the outer wall at the bottom of the driving seat 9. The driving seat 9 slides in the groove, thereby conveniently and directly driving the mounting plate 10 to move.

[0032] Reference Figure 2 The mounting plates 10 on the two driving components 7 are respectively fixedly connected with a receiver 8 and a distance sensor 11, and the receiver 8 and the distance sensor 11 are symmetrically arranged. Through the cooperation between the receiver 8 and the distance sensor 11, it is convenient to detect the distance between the two mounting plates 10.

[0033] Reference Figure 3 The contact assembly 12 includes a detection tube 13 fixedly connected to the mounting plate 10, and a sliding column 14 is slidably connected to the inner wall of the detection tube 13. The detection tube 13 is provided to facilitate the sliding of the sliding column 14 inside the detection tube 13.

[0034] Reference Figure 3 One end of the sliding column 14 is fixedly connected to a U-shaped seat 15, and the outer walls on both sides of the U-shaped seat 15 are rotatably connected to the same roller 16, and the chain is compressed by the roller 16, so that the chain can be moved while being compressed.

[0035] Reference Figure 3 A push switch 18 is fixedly connected to the inner wall of the detection tube 13, and a spring 17 is fixedly connected between the push switch 18 and the sliding column 14. The setting of the spring 17 facilitates triggering the push switch 18 when it is compressed.

[0036] Reference Figure 2 A servo motor 6 is fixedly connected to the outer wall of one side of the detection seat 4, and the output shaft of the servo motor 6 is fixedly connected to the bidirectional screw 5. The servo motor 6 directly drives the bidirectional screw 5 to rotate, and then directly drives the driving component 7 to move toward or away from each other.

The setting of the electric telescopic rod 2 facilitates the lifting and lowering of the detection mechanism 3.

[0038] The implementation principle of the present application is: during use, when it is necessary to detect the width of the chain, first start the electric telescopic rod 2 to push the detection mechanism 3 downward. When the two contact components 12 are moved to both sides of the chain, start the servo motor 6 directly. The servo motor 6 directly drives the bidirectional screw 5 to rotate. When the bidirectional screw 5 rotates, it directly drives the two drive components 7 to move toward or away from each other. When the two drive components 7 move toward each other, the two contact components 12 clamp the chain. During the clamping process, the two springs 17 are compressed. When the push switch 18 is triggered, the servo motor 6 stops. At this time, the distance measuring sensor 11 cooperates with the receiver 8 to measure the distance, which is the width of the chain.
