[0034] In this embodiment, in order to achieve the effects of quickly loading and unloading studs and continuous switching, the installation and switching component 5 is designed. A rotating column 5-1 is rotatably connected at the central position of the platform 3. An external gear 5-2 is provided at the bottom of the rotating column 5-1. A switching motor 5-3 and a driving gear 5-4 are installed at the bottom of the platform 3.

The studs pass through the bottom holes. Two fixed sleeves 5-15 are provided on the surface of the platform 3, and a pressing frame 5-16 is installed in the fixed sleeves 5-15. The pressing frame 5-16 is used to press on the top of the stud being detected. The pressing frame 5-16 remains pressed down at the top, and a relative force is formed in cooperation with the torque detection at the bottom of the stud, so that torques can be generated at both ends of the stud simultaneously.

[0035] Further, the cross-sections of the connection between the lifting column 4-7 and the transmission sleeve frame 4-6 are both rectangular structures.

[0036] In this embodiment, through the rectangular structure transmission, the transmission sleeve frame 4-6 can drive the lifting column 4-7 during rotation and simultaneously has a telescopic effect.

[0037] Furthermore, the limiting block 5-5 has a polygonal structure, and the number of the limiting grooves 5-6 matches the number of the mounting grooves 5-13.

[0038] In this embodiment, due to the polygonal structure, each time the detection disc 5-12 switches, through the insertion and cooperation of the limiting block 5-5 and the limiting groove 5-6, the detection disc 5-12 can be kept stable and not rotate during the detection process.

[0039] Furthermore, the position of the blanking cylinder 5-9 after each switch is on the same axis as that of the mounting groove 5-13.

[0040] In this embodiment, due to the same axis position, after the stud is detected, through the telescopic function of the blanking cylinder 5-9, the supporting plate 5-10 can push the stud outwards, which is convenient for taking it off.

[0041] When detection is required, screw the nut matching the detection torque onto the upper end of the stud to be detected, and then place it into the mounting groove 5-13 of the detection disc 5-12. Start the switching motor 5-3, drive the external gear 5-2 through the driving gear 5-4, so that the rotating column 5-1 rotates. After rotating to the detection position, start the lifting screw rod 4-2, and the lifting platform 4-4 moves upwards. A nut for detecting the torque is also placed in advance in the transmission groove 4-9 of the lifting column 4-7. When the lifting platform 4-4 moves upwards, start the test motor 4-5 at the same time. The test motor 4-5 drives the transmission sleeve 4-6 to rotate with the lifting column 4-7, and the nut is screwed and connected to the lower end of the stud. After the screwing connection, it will continue to rise, and the moving height of the lifting platform 4-4 is synchronized with the moving height of the nut until the torque is detected. After completion, reset, and the rotating shaft rotates again. After the detected stud rotates to directly above the supporting plate 5-10, start the blanking cylinder 5-9, and the blanking cylinder 5-9 pushes the stud outwards and then it can be taken away.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
