Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts detection, in particular to an automobile air inlet and outlet pipe inspection test device. Background Art

[0002] The air inlet and outlet pipes of a car are important components of the car, which can ensure the normal use of the intake and exhaust structures of the car engine. At present, during the production and processing of the air inlet and outlet pipes of the car, it is necessary to inspect and test the sealing of the air inlet and outlet pipes to ensure that the air inlet and outlet pipes can be stably and qualifiedly used in the car.

[0003] The inventor discovered during the process of implementing the utility model:

[0004] When testing the inlet and outlet pipes of a car, one end of the inlet and outlet pipe is blocked by a plugging piece, and the other end is connected to a pressurized pipe. The inlet and outlet pipe is placed in a water pool and pressurized inside the pipe. By observing whether there are bubbles in the pipe body, it can be determined whether there are leaks or poor sealing problems in the inlet and outlet pipes of the car. Generally, the size of the joint is fixed and can only match the inlet and outlet pipes of the corresponding model. When testing different pipes, it is necessary to replace the detection head or use another detection device to match different types of pipes, which is more cumbersome. At the same time, after the test is completed, the water on the surface of the pipe needs to be blown off manually, which affects the test efficiency and increases the labor cost.

[0028] The working principle of this utility model:

[0029] First, the device is placed at the designated position, and then the device is electrically connected to the external power supply. Then, the staff puts the air inlet and outlet pipes 8 on the second support plate 602, and clamps and fixes the air inlet and outlet pipes 8 through the fixing plate 603, the telescopic rod 604 and the clamping plate 605 to prevent the air inlet and outlet pipes 8 from shaking or deflecting during the movement. Then, the staff controls the first electric push rod 601 to operate through the control device, and pushes the second support plate 602 with the air inlet and outlet pipes 8 to the designated position. Then, the staff controls the external driving device and the second electric push rod 704 to operate through the control device, and sleeves the detection ring 705 on the surface of the air inlet and outlet pipes 8.

[0030] Then the staff controls the motor 201 to operate through the control device, and the motor 201 drives the first threaded rod 202 and the second threaded rod 203 to rotate, and the first threaded rod 202 and the second threaded rod 203 respectively drive the threaded cap 204 threadedly connected to their surfaces to move, and the threaded cap 204 drives the first connecting rod 205 fixed on its surface to move synchronously, thereby driving the first sealing block 301 and the second sealing block 302 fixed on the side of the first connecting rod 205 to move toward each other. When the first sealing block 301 and the second sealing block 302 completely seal the two ends of the inlet and outlet air pipe 8, the staff can control the motor 201 to stop operating through the control device, and then control the first electric push rod 601 to operate through the control device, so as to drive the fixed plate 603, the telescopic rod 604 and the clamping plate 605 fixed at the upper end of the first electric push rod 601 to move downward, so that the clamping plate 605 is separated from the inlet and outlet air pipe 8, and the height of the clamping plate 605 is lower than the detection ring 705, so as to avoid the telescopic rod 604 and the clamping plate 605 from interfering with the movement of the detection ring 705;

[0031] Finally, the staff introduces air into the inlet and outlet air pipes 8 through the ventilation pipe 303, and controls the external driving device through the control device to drive the second connecting rod 703 to move, and drive the placement plate 701 fixed at the lower end of the second connecting rod 703 to move, thereby driving the detection ring 705 fixed on the lower surface of the placement plate 701 to move synchronously, and then detect whether the inlet and outlet air pipes 8 are leaking or the leakage position; when a leak occurs on the surface of the inlet and outlet air pipes 8, the gas leaks through the leakage position, and when the detection ring 705 passes the leakage position, the airflow sensor 706 fixed on the surface of the detection ring 705 can sense the gas with a faster flow speed, thereby detecting the leakage position.
