The third cylinder 15 is fixed on the positioning plate 3 through a cylinder block 16, and when the third cylinder 15 extends out, the third cylinder can push the detection pin 13 to be pressed on the product 7, so that the sealing purpose is achieved. The first air cylinder 11 is fixed on the supporting seat 19 through the connecting plate 12 and is connected with the pen cap 10, and the dotting pen 9 is installed in the pen cap 10. When the product 7 is qualified in the tightness test, the first air cylinder 11 drives the dotting pen 9 on the pen cap 10 to extend out and touch the product 7, so that the purpose of dotting is realized.

The device positioning seat 6 is partially structured as follows: the air inlet connector 20 is connected with the positioning seat 6, the positioning seat 6 is fixed on the positioning plate 3, the sealing bush 22 is fixed on the positioning seat 6 through a bolt 23 with a hole, and the first O-shaped ring 21 is positioned between the sealing bush 22 and the positioning seat 6 and used for sealing the sealing bush and the positioning seat. The product 7 is inserted into the sealing bush 22, positioned and sealed.

The device supporting seat 19 is partially structured as follows: the detection pin 13 is connected with the handle connecting block 30 and slides in the bushing 31, so that the calibration pin 13 can be smoothly inserted into the mouth of the product 7, and the product is qualified in size. The second air cylinder 14 contracts to drive the pressing plate 18 to press the product 7 to the limiting block 32. The third cylinder 15 is connected with the second pressing block 34, the third cylinder 15 drives the second pressing block 34 to tightly push the detection pin 13, so that the second O-shaped ring 33 on the detection pin 13 is sealed on the inclined plane of the product, and the purpose of sealing is achieved. And after the product tightness is detected to be qualified, dotting and marking by using a dotting pen 9.

The beneficial effects of the utility model reside in that, process such as compatible leakproofness detects, size detection and dotting sign fuses one process, saves frequent last unloading time, saves the manual work to can improve production efficiency.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Combine the utility model discloses an it is shown that attached figure 1, attached figure 2, attached figure 3, during the airtight test of product, operating personnel inserts sealed bush 22 to product 7 one end in, then compresses tightly product 7 with pressing pincers 4. At this time, if the corrugated pipe part of the product 7 can be simultaneously placed in the groove of the corrugated pipe detection block 8, the next step is carried out, otherwise, the corrugated pipe size of the product is unqualified. The handle 17 is pushed to drive the detection pin 13 to detect the size of the other end of the product 7. If the inspection pin 13 can be inserted, the next step is performed, otherwise the end of the product is not dimensioned. At this point, the dimensional inspection of the product is completed and a subsequent leak test is performed. When the device button is actuated, the rod of the second cylinder 14 is retracted to pull the pressing plate 18 to press the product 7 against the stopper 32. The rod of the third cylinder 15 extends out to drive the second pressing block 34 to prop against the handle connecting block 30, so that the second O-shaped ring 33 of the detection pin 13 is forced to be pressed on the product 7, and sealing is realized. The detection gas enters the interior of the product 7 from the gas inlet connector 20 through the positioning seat 6 and the perforated screw 23. After the pressure is maintained for a period of time, an airtight instrument on the equipment can detect and judge whether the exhaust pipe leaks or not through the change of the gas pressure.
