DETAILED DESCRIPTION

[0052] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] In the prior art, the workpiece is placed on a pressure test bench of an air tightness test device, the workpiece is connected to a compressed air source through a thread or flange, and compressed air is introduced into the inner cavity of the workpiece; when the pressure inside the workpiece is stable, the workpiece is immersed in water or smeared with soapy water, and the sealing of the workpiece is judged by observing whether there are bubbles overflowing from the outer surface of the workpiece. When the test is completed, the workpiece is taken out of the water (or the soapy water is removed), and the threaded or flange connection is removed. For workpieces that fail the air tightness test, they need to be placed on an ultrasonic testing device for positioning inspection and repair, and after repair, they need to be tested for air tightness again.

[0054] However, during the inspection process of the workpiece, the disassembly, immersion and removal of the workpiece need to be done manually. One person can only complete the test of a single test piece at a time, which is inefficient. For workpieces that fail the airtightness test, they need to be re-positioned and inspected on ultrasonic testing equipment, such as water immersion or water film, to determine the defect repair plan and perform the repair. Moreover, for workpieces with leakage during airtightness testing, the workpiece needs to be moved to the ultrasonic testing platform and the secondary water injection is positioned using ultrasonic testing, which is complicated and inefficient.

By moving the detection component along the track, the workpiece moves to the bottom of the frame, and when the center of the sealing member is aligned with the center of the workpiece, the sealing member descends, so that the table sealing surface and the workbench sealing surface are pressed and sealed to form a sealed air cavity, and the sealed air cavity is used to pass gas, so as to facilitate pressurization. The testing platform drives the workpiece to rise, so that the sealing surface of the workpiece is pressed against the sealing surface of the workpiece to form a sealing water tank, and water is poured into the sealing water tank to observe the airtightness effect. One end of the ultrasonic component is connected to the sealing water tank to facilitate ultrasonic testing of the sealing water tank. Two processes are completed by one water injection into the sealing water tank, reducing the operation steps and improving efficiency.

At least one of the testing platform 410 and the sealing member 110 moves relative to the other, so that the testing platform 410 and the workpiece 10 are both sealed with the sealing member 110. The workpiece 10 and the testing platform 410 form a sealed water tank 500. One end of the ultrasonic component 300 is used to be connected to the sealed water tank 500. The sealing member 110, the workpiece 10 and the testing platform 410 are surrounded by a sealed air cavity 600, and the sealed air cavity 600 is used to pass gas.

[0058] Specifically, the rack 100 is erected above the track 200. The rack 100 and the track 200 can both be arranged on a base, and the base is connected to the surface to be installed, such as the surface to be installed can be the ground. Of course, the rack 100 and the track 200 can also be directly installed on the ground. The embodiment of the present application does not limit the number of tracks 200. For example, the number of tracks 200 can be one, and a corresponding moving part 414 is arranged at the bottom of the rack 100, or the number of tracks 200 can be three, which are arranged at intervals on the base or the surface to be installed, and three moving parts 414 are arranged at the bottom of the rack 100, such as each moving part 414 is arranged at intervals at the bottom of the detection platform 410, and is connected to the moving parts 414 one by one.

[0059] An opening is provided in the middle of the rack 100, and the ultrasonic assembly 300 is provided on the side of the rack 100 away from the track 200, and the ultrasonic assembly 300 is located on the peripheral side of the opening, and the ultrasonic assembly 300 is installed on the upper end surface of the rack 100.

A guardrail is provided on the side of the work platform 140 away from the ultrasonic assembly 300 to play a protective role.

[0060] A sealing member 110 is provided on one side of the frame 100 facing the track 200. The sealing member 110 is lifted and lowered in the vertical direction. The sealing member 110 has a table sealing surface 111 and a workpiece sealing surface 112. The table sealing surface 111 is used to compress and seal with the table sealing surface 411 to form a sealed air cavity 600. The sealed air cavity 600 is used to pass gas to perform air tightness testing. The workpiece sealing surface 112 is used to enclose a sealed water tank 500 with the sealing surface 11 of the workpiece 10. One end of the ultrasonic component 300 is used to connect with the sealed water tank 500 to perform ultrasonic testing on the workpiece 10.

[0061] When in use, the detection platform 410 moves along the track 200, so that the workpiece 10 moves to the bottom of the frame 100. When the center of the seal 110 is aligned with the center of the workpiece 10, the seal 110 descends so that its table sealing surface 111 is in contact with the workbench sealing surface 411 and pressurized and sealed. Thus, the first seal is formed. Then, the lifting cylinder of the lifting member 420 pushes the workpiece 10 so that the sealing surface 11 of the workpiece 10 is pressed and sealed with the workpiece sealing surface 11. Thus, the second seal is formed. After the two seals, a sealed water tank 500 is formed above the lifting sealing plate of the main frame, and below, an air pressure sealing chamber 600 is formed by the detection platform 410, the workpiece 10 and the seal 110.

The vent is connected to the air pressure sealing chamber 600 through the pipeline, and gas is introduced into the air pressure sealing chamber 600 to pressurize the air pressure sealing chamber 600. When the pressure reaches the detection standard, whether bubbles are generated or the air pressure is maintained in the sealed water tank 500 is observed, so as to determine whether the workpiece 10 meets the sealing requirements.

[0064] After the inspection is completed, the ventilator 413 evacuates the air in the air pressure sealing chamber 600 to restore the internal air pressure to normal, the water tank evacuates the water in the sealed water tank 500 through the water pump and the pipeline, and the sealing member 110 rises to separate the table sealing surface 111 from the workbench sealing surface 411.
