[0030] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0031] This embodiment provides a transmission housing air tightness detection device, which can be used to detect the air tightness of the cavity and the oil channel.

[0032] refer to Figure 1 As shown in , the detection equipment of this embodiment mainly includes: a cavity airtight device 1, an oil channel airtight device 2, a leak detector 3, and a turnover assembly 4. The cavity airtight device 1 is mainly used to detect the airtightness of the transmission housing and, in the event of a leak, can determine the leak point through water testing. After the cavity airtightness test is completed, the housing is directly rotated to the adjacent oil channel airtight device 2 via the turnover assembly 4, and the oil channel airtight device 2 is used to detect the airtightness of the oil channel in the housing. Preferably, the cavity airtight device 1 and the oil channel airtight device 2 use the same leak detector 3.

[0033] refer to Figure 2 、 3 As described in Figures 4 and 4, in this embodiment, the cavity airtight device 1 mainly includes a cavity detection shift assembly, a water tank 17, a cavity detection main lifting assembly 11, a cavity sealing fixture 13, and a water tank lifting assembly 12.

[0034] The cavity inspection shift assembly mainly includes a placement track 15, an inspection track 16, and a cavity inspection workbench 14. The shell workpiece is first manually placed on the cavity inspection workbench 14 located on the placement track 15, secured with a fixture, and then driven by the relevant drive cylinder to drive the cavity inspection workbench 14 onto the inspection track 16. At this time, the workpiece is moved below the cavity sealing fixture 13 and above the water tank 17.

[0035] The cavity sealing fixture 13 is connected to the cavity detection main lifting assembly 11 and is driven by the cavity detection main lifting assembly 11 to achieve lifting and lowering movement. When the workpiece moves below it, it will drive the cavity sealing fixture 13 to move downward to the set position. The cavity sealing fixture 13 will be activated to press and seal the workpiece, and then the airtightness can be tested by the leak detector 3. In the above structure of this embodiment, the cavity airtight fixture 13 mainly includes a cavity sealing fixture plate 131, a cavity detection sealing head 133 and a cavity detection limit pressing head 132. The cavity airtight fixture 13 adopts an integrated and detachable design. The equipment can realize the airtightness test of the torque converter cavity by replacing the fixture corresponding to the torque converter.

[0036] In this embodiment, the water tank 17 is located at the bottom and is connected to the water tank lifting assembly 12. When the cavity sealing performance is detected to be qualified, the water tank 17 does not move. When the cavity sealing performance is detected to be unqualified, the water tank lifting assembly 12 moves, raising the water tank 17 upward, allowing the shell workpiece to enter the water tank 17. At this time, the leak point can be promptly determined by observing the water level in the water tank 17.

[0037] After the air tightness test of the workpiece, the worker can move the workpiece to the oil channel airtight device 2 on one side through the turnover assembly 4. Figure 5 As shown, the oil channel airtight device 2 mainly includes an oil channel detection shift assembly 23, an oil channel detection main lifting assembly 21, and an oil channel sealing fixture 22; wherein, the workpiece is clamped and fixed at the position of the oil channel detection shift assembly 23, and then moved to the bottom of the oil channel sealing fixture 22, and the oil channel detection main lifting assembly 21 drives the oil channel sealing fixture 22 to move downward to the set position, and the workpiece is fixed and the hole is sealed by the oil channel sealing fixture 22, and then the air tightness test can be carried out by the leak detector 3.

[0038] refer to Figure 6As described above, the oil channel sealing fixture 22 includes an oil channel sealing fixture plate 221, multiple oil channel detection plugging heads 223 and an oil channel detection limit pressing head 222. The oil channel detection plugging head 223 and the oil channel detection limit pressing head 222 are integrated and installed on the small surface of the oil channel sealing fixture plate 221. The oil channel sealing fixture 22 can be replaced to enable the equipment to realize air tightness detection of the torque converter oil channel.
