[0030] Embodiment 2

[0031] like Figure 1-3 As shown, an air pump 5 is fixedly connected to the top of the top plate 4, and a ventilation pipe 6 is connected to the air pump 5. The end of the ventilation pipe 6 away from the top plate 4 is fixedly connected to a limit plate 15. Two limit plates 15 are arranged on the ventilation pipe 6. An airbag 16 is fixedly connected between the limit plates 15. A branch pipe 17 is fixedly connected to the ventilation pipe 6. The branch pipe 17 passes through the limit plate 15. The branch pipe 17 is fixedly connected to the airbag 16. By arranging the branch pipe 17 between the ventilation pipe 6 and the airbag 16, the airbag 16 is connected to the branch pipe 17, and the gas in the branch pipe 17 can be flushed into the interior of the airbag 16 to expand the airbag 16, so that the auxiliary tooling can seal workpieces of different sizes to be tested, so that the auxiliary tooling can adapt to workpieces of different sizes.

[0032] One side of the clamp 8 is fixedly connected to a movable plate 19, and a slide rod 10 is rotatably connected to the movable plate 19. The side of the clamp 8 away from the movable plate 19 is fixedly connected to a movable plate 2 18, and a bidirectional screw rod 11 is threadedly connected to the movable plate 2 18. Both ends of the slide rod 10 and the bidirectional screw rod 11 are rotatably connected to a fixed plate 12, and the bottom of the fixed plate 12 is fixedly connected to the top of the base 7. By threading the movable plate 2 18 and the bidirectional screw rod 11, the movable plate 2 18 is rotated, so that the movable plate 2 18 drives the clamp 8 to move along the slide rod 10 toward the workpiece, so that the workpiece is supported and fixed.

[0033] The fixture 8 is fixedly connected to a fixing block 19, the inner wall of which is an arc-shaped structure. By providing the fixing block 19 with an arc-shaped inner wall, the auxiliary tooling can support workpieces of different sizes, thereby improving the versatility of the tooling.

The air pump 5 sends air into the workpiece through the vent pipe 6. At the same time, the air inside the vent pipe 6 is sent into the airbag 16 along the branch pipe 17, so that the airbag 16 expands and seals the workpiece, and finally the motor 14 is started. The motor 14 drives the gear 13 to rotate, and the gear 13 drives the rack 3 and the top plate 4 to move downward, and the top plate 4 drives the bracket 20 to move into the solution, and observe whether there are bubbles coming out of the workpiece.
