However, the existing wet brake test assembly tooling adopts closed assembly, which is invisible to the naked eye during the assembly process. After closing, either the gap is not adjusted properly or the pressure spring is not adjusted in place. When the seal ring is finally closed, it is often cut and damaged, which is difficult to find during the pressure test. However, when customers use it, they often find oil leakage.

[0007] As a further solution of the utility model: a piston, a spring, a brake pad I and a friction pad are placed in sequence inside the lower housing of the wet brake.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.
[0017] like Figure 1 , Figure 2 As shown, the wet brake assembly tooling includes a support frame, a wet brake lower shell 2 is placed above the support frame, a detachable plate-shaped cover plate 5 is arranged above the wet brake lower shell, and in order to further press the internal components of the wet brake, a circular ring-shaped pressure plate 10 is fixedly connected below the cover plate 5; an observation hole 1 is formed between the cover plate 5 and the pressure plate 10, through which it can be seen whether there is oil leakage and component manufacturing defects during the working process.
[0018] like Figure 2 As shown, bolt holes 9 are provided at the four corners of the cover plate 5. During the hydraulic test, long-rod bolts are used to connect the cover plate to the lower housing 2 of the wet brake. When connected, the long-rod bolts are inserted into the bolt holes of the cover plate from the bottom of the lower housing of the wet brake and fixed with nuts 4.
[0019] like Figure 1 , Figure 2 As shown, in order to facilitate taking the cover plate, a ring handle 6 is welded at the center position above the cover plate 5.
[0020] like Figure 4 As shown, the piston 11, spring 12, brake pad 113 and friction pad 8 of the wet brake are placed in sequence inside the lower housing 2 of the wet brake.
[0021] like Figure 2 As shown, the friction plate and brake plate 1 are fixed inside the lower housing of the wet brake by a pin shaft 7. An oil-resistant rubber tube 3 is connected to the lower housing 2 of the wet brake. The oil-resistant rubber tube 3 is connected to the pressure test oil inlet, that is, when the hydraulic test is performed, oil is introduced through the oil-resistant rubber tube. The oil-resistant rubber tube is connected to the hydraulic element.
[0022] like Figure 3 As shown in the figure, the overall structure diagram of the wet brake is as follows: Figure 4 As shown, the internal cross-sectional view of the wet brake includes a piston 11, a spring 12 is embedded on the piston 11, and the spring 12 is fixedly connected to the inside of the wet brake by bolts. A brake pad I13 and a friction pad 8 are connected above the piston 11. The brake pad I13 and the friction pad 8 are installed side by side in sequence with intervals, and a brake pad II14 is connected above the top friction pad 8. The pressure plate 10 in the wet brake assembly tool of the utility model is equivalent to the brake pad II14.

After adjusting the gap position, the cover plate 5 is placed on the upper part of the lower housing of the wet brake, and the cover plate 5 is fixed by the long rod bolt, and the long rod bolt is inserted into the cover plate bolt hole 9 from the bottom of the lower housing of the wet brake, and fixed with the nut 4; the use of the long rod bolt to fix from bottom to top can ensure the stability of the wet brake during the hydraulic test; the power is turned on, and hydraulic oil enters the oil-resistant rubber tube 3, and the wet brake assembly tooling is repeatedly pressure tested. Through the observation hole, it can be checked whether there is oil leakage. After there is no problem, the cover plate 5 is removed, and then the support shaft is assembled into an integral lower frame to complete.
