[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1:

[0028] See also Figure 1-Figure 5The present application provides an airtightness detection equipment for glass fiber composite material processing, including a main frame 1, and also including a No. 1 limiting mechanism, which is arranged on the main frame 1, and the No. 1 limiting mechanism limits and fixes the glass fiber composite material in the longitudinal direction; the No. 2 limiting mechanism is arranged below the No. 1 limiting mechanism, and the No. 2 limiting mechanism limits and fixes the glass fiber composite material in the horizontal direction. The limiting block 32 driven by the No. 2 cylinder 31 limits and fixes the front and back of the tested box. At the same time, the No. 3 cylinder 5 drives the upper pressure frame 51 to limit downward, fully covering the upper end of the tested box. In addition, the use of the limiting rod 41 and the limiting sleeve 53 makes the tested box effectively fixed in the left and right directions, which fully guarantees the stability and safety of the detection, effectively prevents the detection error caused by shaking or displacement, and improves the accuracy and reliability of the detection.

[0029] The No. 1 limiting mechanism includes a No. 3 cylinder 5 fixedly connected to the main frame 1, the output end of the No. 3 cylinder 5 is fixedly connected to the upper pressure frame 51, the upper end of the upper pressure frame 51 is fixedly connected to several guide shafts 52, and a sliding sleeve 13 is fixedly connected to the main frame 1, and the guide shaft 52 is slidably connected to a sliding sleeve 13.

[0030] Specifically, by starting the No. 3 cylinder 5, the upper pressure frame 51 is driven to move downward until the upper pressure frame 51 is limited and covers the upper end of the tested box, the tested box is further limited and fixed to ensure its stability during the air tightness test.

[0031] In this embodiment, the No. 2 limiting mechanism includes a fixed block 3 fixedly connected to the No. 1 cylinder 2, the No. 2 cylinder 31 is fixedly connected to the fixed block 3, and the output end of the No. 2 cylinder 31 is fixedly connected to the limiting block 32.

[0032] Specifically, the No. 2 cylinder 31 provided at the front and rear sides of the tested box is started simultaneously, and the No. 2 cylinder 31 drives the limit blocks 32 to limit and fix the front and rear sides of the tested box to ensure the stability of the tested box.

[0033] In this embodiment, a connecting seat 12 is fixedly connected to the main frame 1, a connecting block 21 is fixedly connected to the output end of the connecting seat 12, a placement plate 22 is fixedly connected to the connecting block 21, a slide rail 11 is provided on the main frame 1, and the placement plate 22 is slidably connected to the slide rail 11.

[0034] Specifically, by starting the No. 1 cylinder 2 to drive the connecting block 21 to move away from the No. 1 cylinder 2, the connecting block 21 drives the placement plate 22 to slide along the slide rail 11, and then the box to be tested filled with glass fiber composite material is placed on the placement plate 22. After the No. 2 limit mechanism is limited and fixed, the No. 1 cylinder 2 is started again to drive the placement plate 22 and the box to be tested on the placement plate 22 to be transported to the detection area and moved to the bottom of the No. 1 limit mechanism.

[0035] In this embodiment, the placement plate 22 is also fixedly connected to a No. 1 connecting member 4, the upper end of the No. 1 connecting member 4 is fixedly connected to a limiting rod 41, and the upper pressure frame 51 is fixedly connected to a limiting sleeve 53, the limiting sleeve 53 is slidingly arranged with the limiting rod 41, and the main frame 1 is fixedly connected to a No. 2 connecting member 6, and the No. 2 connecting member 6 is provided with a limiting bolt 61, which is used to physically limit the placement plate 22 sliding on the slide rail 11, so as to avoid the problem that the placement plate 22 is separated from the slide rail 11 due to the distance being too far during the pushing process.

[0036] Specifically, during the downward movement of the No. 1 limit mechanism, the guide shaft 52 slides downward along a sleeve 13 to play a guiding role. Secondly, the limit sleeve 53 slides and is inserted into the outside of the limit rod 41, and limits and fixes the left and right sides of the tested box to comprehensively protect the stability of the tested box.

[0037] In this embodiment, a hydraulic station 10 is provided at the upper end of the main frame 1 , and the hydraulic station 10 provides necessary power for the No. 1 cylinder 2 , the No. 3 cylinder 5 and the No. 2 cylinder 31 .

The protective net 14 is provided on the two sides and the back of the main frame 1 to be tested, effectively isolating the test area and preventing the staff from putting their hands or other parts into the test area due to misoperation or curiosity during the test process, thereby avoiding possible mechanical injuries. At the same time, the protective grating 15 provided at the entrance can immediately respond and stop the equipment when a person or object attempts to pass through, ensuring the safety of the personnel. The main frame 1 is also fixedly connected to a fixing frame 8, and an operating console 9 is provided on the fixing frame 8 for operating the sealing test equipment. Specifically, when the airtightness equipment is tested, the system will fill the gas into the tested box at a fast and slow speed. After a certain period of time, the air pressure will stabilize in the area - the stable value. After the set stable time, the test value is compared with the stable value. If the object to be tested does not leak, the equilibrium state will be maintained. If there is a leak in the object being tested, the pressure inside it will gradually decrease, and the air pressure in the box will also decrease. When the pressure difference value is exceeded, a direct sound and light unqualified alarm will be issued. These are all existing technologies and are only used for them.

[0041] On the basis of Example 1, the lower end of the main frame 1 is threadedly connected to a screw rod 7, and the screw rod 7 on each tripod 72 can be individually threadedly adjusted to adjust the distance between each tripod 72 and the main frame 1, thereby ensuring the stability of the main frame 1 and preventing the main frame 1 from shaking easily due to uneven ground. The lower end of the screw rod 7 is fixedly connected to the tripod 72, and a nut 71 is provided on the screw rod 7.
