[0039] The vertical rod 209 is connected to a first end of a return spring 215 , and a second end of the return spring 215 is mounted on the detection bracket 101 .

[0040] The working principle of the present invention is as follows: a stainless steel pipe that needs to be tested for air tightness is thrown in from one side of the transfer shell 102, the steel pipe rolls into the transfer shell 102, and falls between two of the partition plates of the two transmission wheels 104, and the detection motor 301 is started to drive the incomplete feeding gear 112 to rotate, and the incomplete feeding gear 112 drives the disc 303 to rotate through the belt 302, and the incomplete feeding gear 112 rotates one circle to drive the disc 303 and the feeding gear 111 to rotate one circle, and the feeding gear 111 drives the incomplete feeding gear 107 and the feeding reciprocating screw 108 to rotate one circle, and drives the two centering push plates 109 to reciprocate once, and when the two centering push plates 109 move relative to each other, they push the yield spring 110 and the push disk 103 to move, and the push disk 103 drives the transmission wheel 104 to move, and the steel pipe is moved to the center position through the relative movement of the two push disks 103, and steel pipes of different lengths are adaptively adjusted by the yield spring 110.

[0041] Each rotation of the incomplete feeding gear 107 drives the feeding gear 106 to rotate a preset angle, and drives the spline shaft 105 and the transmission wheel 104 to rotate a preset angle. Each time the transmission wheel 104 rotates once, the steel pipes accumulated at the discharge port at the feeding position of the transfer shell 102 fall into between the partition pieces of the transmission wheel 104, and then the rotating transmission wheel 104 drives the steel pipes to roll out from another discharge port of the transfer shell 102 and roll onto the guide inclined plate 113.

[0042] By starting the detection motor 2 321, the support gear 1 322 is driven to rotate, which drives the support gear 2 323 to rotate, drives the rotating shaft 312 to rotate, and drives the limit plate 313 to rotate, so that the opening direction of the limit plate 313 is toward the guide inclined plate 113, and the steel pipe rolls down from the inclined guide inclined plate 113 and rolls onto the guide inclined plate 113. Then the detection motor 2 321 drives the rotating shaft 312 and the limit plate 313 to rotate again, so that the opening of the limit plate 313 is facing directly upwards.

[0043] At this time, the position of the steel pipe corresponds to the detection slide 1 308, the detection slide 2 319, and the sealing gasket 320. For steel pipes of different diameters, the height position of the mounting block 318 in the adjustment seat 316 can be adjusted by rotating the adjustment screw 317 so that the axis of the steel pipe corresponds to the axis of the gas pipe 315.

[0044] Start the hydraulic cylinder 307 to extend the piston rod to drive the detection slide 1 308 to move, drive the rack 1 309 to move, drive the detection gear 310 to rotate, drive the rack 2 311 to move, drive the detection slide 2 319 to move, and the detection slide 2 319 and the detection slide 1 308 move relative to each other to clamp the steel pipe, so that the air pipe 315 is inserted into the steel pipe, and the two ends of the steel pipe are respectively in contact with a sealing gasket 320 for sealing.

[0045] The incomplete feeding gear 112 drives the disc 303 and the eccentric column 304 to rotate through the belt 302, drives the detection connecting rod 305 to swing, and drives the lifting frame 306 to drop to the lowest point. Water is placed in the detection bracket 101 to immerse the steel pipe in the water. Then the incomplete feeding gear 112 stops rotating, and the steel pipe is inflated and pressurized for a preset time through the air pump 314 to observe whether bubbles are generated.

[0046] After the detection is completed, the incomplete feeding gear 112 continues to rotate, and drives the lifting frame 306 to rise through the detection connecting rod 305, so that the steel pipe leaves the water body. The hydraulic cylinder 307 retracts the piston rod, and the detection slide 1 308 and the detection slide 2 319 are away from the detected steel pipe. If no bubbles are generated during the detection process, the detection motor 2 321 drives the rotating shaft 312 and the limit plate 313 to rotate in the direction of the separation inclined plate 201, and the detected steel pipe on the limit plate 313 rolls toward the separation inclined plate 201, and then rolls into the lower collection box 202.

[0047] Under normal circumstances, the monitor 206 will monitor the water condition. If bubbles are found, the separation motor 204 will start to drive the separation screw 205 to rotate one circle, driving the monitor 206 to slide a preset stroke on the detection bracket 101. When the monitor 206 slides to the position where bubbles are generated, the marking component 207 sprays a marker to mark the bubble position on the steel pipe.

[0048] The rotation of the separation screw 205 drives the separation turntable 208 to rotate, and the rotation of the separation turntable 208 pushes the vertical rod 209 to move downward, compressing the reset spring 215. The vertical rod 209 pushes the separation connecting rod 210 to rotate, driving the separation connecting plate 212 to move, driving the separation top rod 214 to move upward and push the separation inclined plate 201, so that the separation inclined plate 201 rotates to a position corresponding to the upper collecting box 203, and then when the detection motor 2 321 drives the rotating shaft 312 and the limit plate 313 to rotate in the direction of the separation inclined plate 201, the steel pipe that has been inspected on the limit plate 313 rolls toward the separation inclined plate 201, and then rolls into the upper collecting box 203, separating qualified products from unqualified products, so as to facilitate the subsequent further processing of the leaking steel pipe.
