For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1 - Figure 4 As shown, in this embodiment, a bellows sealing detection device includes a base 1, a detection box 2 and an adjusting component, the adjusting component including a rotating disk 3; the surface of the rotating disk 3 is rotatably connected to the inner wall of the detection box 2; an electric telescopic rod 4 is fixedly connected to the center of one side of the rotating disk 3; the electric telescopic rod 4 is fixedly connected to a sealing chuck 5 at one end away from the rotating disk 3; the surface of the sealing chuck 5 is fixedly connected to a spring telescopic rod 6; the end of the spring telescopic rod 6 away from the sealing chuck 5 is fixedly connected to the surface of the rotating disk 3; the surface of the sealing chuck 5 is threadedly connected to a positioning screw 7; one end of the positioning screw 7 is fixedly connected to a crescent block 8; the inner wall of the detection box 2 away from the rotating disk 3 is fixedly connected to an air guide nozzle 9; the surface of the air guide nozzle 9 is clamped with a bellows 10 to be detected; the surface of the bellows 10 to be detected away from the air guide nozzle 9 is provided with a sealing clamp ring sleeve 11.

[0022] Through the above technical scheme, the adjustment component is arranged inside the detection box 2. When working, the bellows 10 to be detected is clamped in the sealing clamp ring sleeve 11, and the sealing clamp ring sleeve 11 seals the bellows 10 to be detected, and then the bellows 10 to be detected are clamped into the sealing chuck 5 together with the sealing clamp ring sleeve 11, and the positioning screw 7 is rotated to drive the crescent clamp block 8 to move and abut against the surface of the sealing clamp ring sleeve 11, so that the bellows 10 to be detected is fixed and sealed. After fixing, the electric telescopic rod 4 works to drive the sealing chuck 5 to move, and the other end of the bellows 10 to be detected is clamped on the surface of the air guide nozzle 9. During the detection, the rotating disk 3 rotates to drive the electric telescopic rod 4 and the spring telescopic rod 6 to start rotating, and then drives the sealing chuck 5 to rotate. Since the bellows 10 to be detected and the sealing clamp ring sleeve 11 are fixed in the sealing chuck 5, the bellows 10 to be detected can rotate with the rotation of the sealing chuck 5, so that when it is uncertain where the defect is located, it can be conveniently observed during rotation, thereby reducing the work intensity of the detection.

[0023] like Figure 2 and Figure 4As shown, a motor base 12 is fixedly connected to one side of the detection box 2; a motor 13 is fixedly connected to the surface of the motor base 12; the output shaft of the motor 13 is fixedly connected to the surface of the rotating disk 3 through a coupling; one end of the positioning screw 7 passes through the sealing chuck 5 and extends to the inside of the sealing chuck 5; the end of the positioning screw 7 located inside the sealing chuck 5 is fixedly connected to the surface of the crescent block 8; the end of the positioning screw 7 away from the crescent block 8 is fixedly connected to an adjusting spline; the number of the spring telescopic rods 6 is set to four, and the four spring telescopic rods 6 are evenly arranged on the surface circumference of the electric telescopic rod 4; the number of the positioning screws 7 is set to four, and the four positioning screws 7 are evenly arranged on the surface circumference of the sealing chuck 5.

[0024] Through the above technical solution, the motor seat 12 is fixed on one side of the detection box 2 and is used to install the motor 13. When the motor 13 is working, the rotating disk 3 is driven to rotate through the output shaft. Four positioning screws 7 are arranged on the surface circumference of the sealing chuck 5. The positioning screws 7 are driven to rotate by adjusting the spline, thereby driving the crescent block 8 to move and fix the sealing clamp ring sleeve 11. In addition, four spring telescopic rods 6 are arranged evenly on the surface circumference of the electric telescopic rod 4 to support the connection between the rotating disk 3 and the sealing chuck 5, and can be extended and retracted along with the extension and retraction of the electric telescopic rod 4 to ensure the stability of the movement of the sealing chuck 5.

[0025] like Figure 1 and Figure 3 As shown, the top of the base 1 is fixedly connected to the bottom of the detection box 2; the top of the detection box 2 away from the motor base 12 is fixedly connected to an air pump base 14; the top of the air pump base 14 is fixedly connected to a working air pump 15; the surface of the working air pump 15 is connected to an air guide hose 16; one end of the air guide hose 16 passes through the air guide nozzle 9 and extends to the interior of the air guide nozzle 9.

[0026] Through the above technical solution, the base 1 supports the detection box 2, and the air pump seat 14 is fixed on one side of the detection box 2. The top of the air pump seat 14 supports and fixes the working air pump 15. The working air pump 15 works to ventilate the air guide nozzle 9 through the air guide hose 16, so that the gas is passed to the bellows 10 to be detected, and water is passed inside the detection box 2. If the sealing of the bellows 10 to be detected is not high, the gas will leak from the bellows 10 to be detected, causing bubbles to appear in the water inside the detection box 2, which is convenient for observation.

[0027] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; the technology not described in detail in the present invention is implemented with the existing technology.
