After production, they often need to be subjected to corresponding testing operations to avoid affecting their actual use.
[0003] The existing leg plate joint pins still have the following problems when tested after production:
[0004] (1) When conducting the test, only the leg plate joint pin can be placed for testing, and it cannot be limited to rotation. Furthermore, testing from multiple angles will reduce the accuracy of the test in practice and will not be conducive to conducting more comprehensive testing operations in reality.
[0005] (2) After testing, it is not convenient to classify and collect qualified and unqualified leg plate joint pins. This will increase the collection burden of staff and the corresponding collection time, which is not conducive to its promotion and use in practice.

[0025] Please see Figure 4 A sorting and collection mechanism 20 is provided on the right side of the testing platform 1. The sorting and collection mechanism 20 includes a rectangular block 16, an electric push rod 17, a rectangular plate 18, and a collection box 15.

[0026] Please see Figure 1 and Figure 2 The testing platform 1 is equipped with brackets 2 on all four sides of its upper surface, and the bottom of each bracket 2 is fixedly installed to the upper surface of the testing platform 1. A connecting plate 3 is fixedly installed on the upper surface of the bracket 2, and an ultrasonic flaw detector 4 is set at the center of the bottom of the connecting plate 3.

[0027] Working principle: During use, when performing limit rotation detection on the leg plate joint pin, the leg plate joint pin can be placed on the upper surface of the receiving plate 13. Then, through the action of the electric slide rail 5 and the electric slider 6, the position of the abutment pad 11 can be moved to the opposite side, thus limiting and clamping the leg plate joint pin. After it is limited, the power of the electric telescopic rod 8 set inside the U-shaped frame 7 can drive the T-shaped sliding block 9 to slide on the inner wall of the U-shaped frame 7, thereby raising the position of the leg plate joint pin. Then, through the power of the servo motor 10, the output shaft of the fixed abutment pad 11 can be rotated, and the limited leg plate joint pin is closed synchronously. The joint pin can be rotated, and after the leg plate joint is properly positioned, the position of the joint pin can be changed left and right by the power of the electric slide rail 5 and the electric slider 6. When the position of the joint pin changes, the joint pin can be inspected by the ultrasonic flaw detector 4. The ultrasonic flaw detector 4 is specifically model TUG500, which has the characteristics of large detection range (2.56000mm) and moderate working frequency (0.510MHz). It can detect, locate, evaluate and diagnose various defects, cracks, inclusions and pores inside the workpiece without damage.
[0028] After the leg joint pin is inspected, the leg joint pin, which is limited on the opposite side of the abutment pad 11, can be lowered by the power of the electric telescopic rod 8. Then, the abutment force of the leg joint pin can be eliminated by the electric slide rail 5 and the electric slider 6, so that the leg joint pin can be placed on the upper surface of the support plate 13 for collection. Depending on the quality of the inspection, different electric push rods 17 can be activated. After determining the quality of the leg joint pin, the corresponding electric push rod 17 can be activated, which can change the position of the rectangular plate 18. Simultaneously, the collection box 15 fixedly installed on the back of the rectangular plate 18 will leave the interior of the inspection table 1, and the fixing block 14 fixedly installed on the back of the collection box 15 can drive the position of the support plate 13 to slide on the inner wall of the inspection table 1. The leg joint pin placed on the upper surface of the support plate 13 can be moved synchronously. After the position of the support plate 13 is moved to the relevant position, the operator can place the moved leg joint pin inside the collection box 15 for collection.
