[0033] Example 2:

[0034] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the short-circuit clamp transmission assembly 8 includes an assembly frame 18, a mounting plate 19, a rodless cylinder 20, a displacement frame 21, and a pushing cylinder 22. The assembly frame 18 is fixedly connected to the side of the bearing plate 1 away from the guide box 2. The mounting plate 19 is fixedly connected to the middle of the assembly frame 18. The rodless cylinder 20 is fixedly connected to the top of the mounting plate 19. The displacement frame 21 is fixedly connected to the output end of the rodless cylinder 20. The pushing cylinder 22 is fixedly connected inside the displacement frame 21. A pusher frame 23 is fixedly connected to the output end. A pneumatic clamp body 24 for fixing the short-circuit clamp is fixedly connected to the top of the pusher frame 23. A leveling cylinder A25 is fixedly connected to the top of the assembly frame 18. A positioning seat 26 is fixedly connected to the output end of the leveling cylinder A25. A leveling cylinder B27 is fixedly connected to one end of the positioning seat 26. A leveling plate 28 is fixedly connected to the output end of the leveling cylinder B27. An extension frame 29 is fixedly connected to the end of the assembly frame 18 away from the leveling cylinder A25. An angle sensor 30 is fixedly connected to one end of the extension frame 29.

[0035] In this embodiment, the pneumatic clamp body 24 is model MHZ2-10, which is a mature existing technology and will not be described in detail here;

[0036] Furthermore, both ends of the bottom of the mounting plate 19 are fixedly connected to reinforcing plates, and the bottom ends of the reinforcing plates are fixedly connected to the bottom of the mounting frame 18. The reinforcing plates can provide auxiliary support for the mounting plate 19.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] Working principle: First, the push cylinder 22 is activated to push the push frame 23 to move linearly, so that the pneumatic clamp body 24 is close to the output end of the vibrating feed plate 31. Then, the vibrating feed plate 31 runs and pushes a short-circuit clamp to the top of the push frame 23. Then, the leveling cylinder A25 is activated to push the positioning seat 26 to move towards the pneumatic clamp body 24. Then, the leveling cylinder B27 is activated to push the leveling plate 28 downward until the leveling plate 28 contacts the short-circuit clamp on the push frame 23, so that the short-circuit clamp is leveled.

[0039] After leveling, the pneumatic clamp body 24 is activated to clamp the short-circuit clamp, and the push cylinder 22 is controlled to run, causing the push frame 23 to retract. Then the rodless cylinder 20 runs, driving the displacement frame 21 to move linearly. When the push frame 23 moves to correspond with the angle sensor 30, the angle of the short-circuit clamp is detected by the angle sensor 30 to determine whether the short-circuit clamp meets the installation standard. If the short-circuit clamp meets the standard, it continues to be transmitted until the short-circuit clamp reaches the end of the rodless cylinder 20.

[0040] The drive motor 6 is restarted, causing the reduction spur gear 7 to shift the drive spur gear 5, which in turn drives the adjustment box 9 to rotate. This causes the adjustment box 9 to move towards the pneumatic clamp body 24, and the adjustment cylinder 15 is activated to pull the assembly seat 16 to move. Since the linkage rod 17 is connected between the eccentric guide plate 14 and the assembly seat 16, when the assembly seat 16 moves, it can pull the eccentric guide plate 14 through the linkage rod 17, which in turn drives the mounting box 11 to rotate independently until the pneumatic chuck body 13 reaches above the pneumatic clamp body 24. The electric push rod 12 is then activated to push the pneumatic chuck body 13 downward. When the pneumatic chuck body 13 contacts the short-circuit clamp, it clamps the short-circuit clamp. Then the pneumatic chuck body 13 rises, and with the activation of the drive motor 6 and the adjustment cylinder 15, the pneumatic chuck body 13 is adjusted to be above the transport mechanism 32. By moving the pneumatic chuck body 13 downward, the short-circuit clamp is installed at the designated position on the gas generator on the transport mechanism 32.
