It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.
[0022] Embodiment: As Figures 1-3 shown, the present utility model provides a carbon canister desorption valve airtight detection device, including a platform base 1 and a positioning tooling 2. The positioning tooling 2 is installed at the top of the platform base 1, and the positioning tooling 2 is used to fix and limit the product to be detected. A side support arm base 3 is installed at the top of the platform base 1, and a main arm 4 of the side support arm is installed at the top of the side support arm base 3. Triangular support arms 16 of the side support arm are installed at the top of the side support arm base 3 and one end of the main arm 4 of the side support arm. The triangular support arms 16 of the side support arm help the side support arm base 3 and the main arm 4 of the side support arm to maintain stability. There are two side support arm bases 3, main arms 4 of the side support arm, and triangular support arms 16 of the side support arm. The two side support arm bases 3, main arms 4 of the side support arm, and triangular support arms 16 of the side support arm are symmetrically and equidistantly distributed on both sides of the positioning tooling 2 with the positioning tooling 2 as the center;
[0023] One end of the main arm 4 of the side support arm is installed with a cylinder 5, one end of the cylinder 5 is installed with a sealing fixture 6, and one end of the sealing fixture 6 is installed with a sealing fixture lock nut 7. There are two cylinders 5, sealing fixtures 6, and sealing fixture lock nuts 7. The two cylinders 5, sealing fixtures 6, and sealing fixture lock nuts 7 are symmetrically and equidistantly distributed on both sides of the positioning tooling 2 with the positioning tooling 2 as the center. The installation heights of the two cylinders 5, sealing fixtures 6, and sealing fixture lock nuts 7 are not equal, so as to cooperate with the characteristics of the product to be detected and make the sealing fixture lock nut 7 better position the air path nozzle of the product;
[0024] At the top of the platform base 1, a rear support arm 8 is installed. At one end of the rear support arm 8, a rear support arm auxiliary arm 17 is installed. At one end of the rear support arm 8, an energized cylinder support 9 is installed. At the top of the energized cylinder support 9, an energized cylinder 10 is installed. At the top of the energized cylinder 10, an energized contact base support 11 is installed. At the top of the energized contact base support 11, an energized contact base 12 is installed, which is used to energize the product.
[0025] At one end of the rear support arm 8, a dotting cylinder 13 is installed. At the bottom end of the dotting cylinder 13, a dotting base 14 is installed through a screw and a nut. There are two nuts, and both nuts are equidistantly installed at the top and bottom ends of the dotting base 14 with the dotting base 14 as the center. The screw penetrates through the dotting base 14, and a dotting probe 15 is installed at the bottom end of the dotting base 14, which is used to perform a fixed-point dotting on the product.
[0026] The working principle and usage process of the present utility model are as follows: First, the staff places the product to be inspected in the placement depression at the top of the positioning tooling 2, and places a part of it on the energized contact base 12. Then, the equipment is started. Subsequently, the two side cylinders 5 will drive the two side sealing clamps 6 to move, and further drive the two side sealing clamp lock nuts 7 to move, so that the sealing clamp lock nuts 7 overlap with the left and right air paths of the product. Then, the sealing clamp lock nuts 7 will tightly hold the air path nozzles of the product, thereby achieving rapid and accurate positioning and improving the detection efficiency.
[0027] Then, the energized cylinder 10 is started to energize the product. Subsequently, the D80 airtight leak detector and the supporting electrical PLC are started to detect the airtight performance of the product. If the product passes the detection, under the action of the dotting cylinder 13, the bolt will move up and down to perform an impact dotting action, and drive the dotting base 14 to move, so that the dotting probe 15 also moves accordingly to perform a fixed-point dotting on the product. If the product fails the detection, the dotting cylinder 13 will not act, and at the same time the equipment will alarm. Thus, efficient continuous detection is achieved, and the overall detection speed and production efficiency are improved.
[0028] After the detection is completed, the sealing clamp lock nuts 7 loosen the air path nozzles of the product, and the energized cylinder 10, the two side cylinders 5, the sealing clamps 6 and the sealing clamp lock nuts 7 move back to their original positions. The staff takes down the product and classifies it for placement.
