The bottom surface of the pressure plate 52 is provided with multiple sealing assemblies for sealing the holes in the oil pan. The sealing assembly includes a connecting rod 54, which is fixedly connected to the pressure plate 52 for connecting various components. A sealing head 56 is provided at the bottom of the connecting rod 54, which is made of rubber. A connecting piece 55 is commonly provided between the connecting rod 54 and the sealing head 56 for installation between the sealing head 56 and the connecting rod 54 to facilitate replacement of the sealing head 56.

At the same time, when the pressure plate 52 is pressed down, the sealing plate 61 will be driven downward by the pressure rod 62, and the sealing gasket 63 will be tightly pressed on the installation port on the upper part of the oil pan. As the pressure plate 52 continues to When the seal 63 is pressed down and contacts the oil pan, the slide bar 622 will slide into the hollow bar 621 and squeeze the spring 623. The spring 623 will react on the slide bar 622 and push the slide bar 622 downward, so that it pushes the seal plate 61 and the seal 63 to close to the oil pan, thereby sealing the installation port on the upper part of the oil pan. Then, air is inflated into the oil pan through the air inlet 12 to test the sealing performance of the oil pan. After the test is completed, the cylinder 51 drives the pressure plate 52 and the plugging assembly and the seal assembly 6 at the lower part to move upward, and then the oil pan can be removed.
