[0022] Example

[0023] Reference Figure 1-3 As shown, this utility model discloses a brake pump pressure testing fixture, including a base plate 10. A fixed seat, a power seat, and a level gauge 104 are provided on the base plate 10. The fixed seat is used to fix the brake pump, the power seat is used to pull and hold the brake lever 503, and the level gauge 104 is connected to the oil outlet 502 of the brake pump, thus completing the pressure test of the brake pump.

[0024] Reference Figure 1-3As shown, the mounting base includes an L-shaped mounting plate 101. The mounting plate 101 has a through hole 1011 on its end face facing the power base. The power base includes a push-pull clamp 102, which is aligned with the through hole 1011. A level gauge 104 is mounted on one side of the mounting plate 101. Specifically, the mounting plate 101 has positioning holes 1013 on both sides of the through hole 1011. The two mounting holes on the through side of the brake pump and the pull rod 503 are aligned with the positioning holes 1013, and the brake pump is locked to the mounting plate 101 with bolts. The pull rod 503 of the brake pump passes through and connects to the push-pull clamp 102. The end of the push-pull clamp 102 near the mounting plate 101 has a shaft hole, through which bolts are quickly connected to the pull rod 503. The oil outlets 502 on both sides of the brake pump are connected to the level gauge 104 through hoses. By moving the push-pull clamp 102, the pull rod 503 is pulled, which simulates the effect of the oil pumping out when braking. The oil in the brake pump cup goes through the hose to the level gauge 104. The pressure value of the brake pump is obtained by observing the scale value of the level gauge 104. Then, by keeping the position of the push-pull clamp 102, a pressure holding test is performed to simulate whether the pressure of the brake pump is constant when the brake is continuously pressed.

[0025] Furthermore, a pressure gauge 103 is installed on the base plate 10, and the pressure gauge 103 is connected to the level gauge 104. The oil from the brake pump passes through the pressure gauge 103 and then through the level gauge 104, which can monitor the pressure of the oil pumped out by the brake pump, making the test more intuitive and reliable.

[0026] Reference Figure 1-3 As shown, the power base further includes a slide rail 1021, with positioning holes 1013 on both sides of the slide rail 1021. The push-pull clamp 102 is slidably mounted on the slide rail 1021. Specifically, the push-pull clamp 102 is slid along the slide rail 1021, and its position on the slide rail 1021 is adjusted according to the length of the pull rod 503 of different brake pumps. Then, the push-pull clamp 102 is fixed through the positioning holes 1013 on both sides of the slide rail 1021, improving the practicality of the tooling.

[0027] In this embodiment, two plugs 1012 are provided on one side of the fixing plate 101. Bolts pass through the fixing plate 101 to lock the plugs 1012. The pressure gauge 103 is connected to the two oil outlet holes 502 on one side of the brake pump and then to the level gauge 104. The two oil outlet holes 502 on the other side are blocked by the plugs 1012. The oil outlet pressure and holding pressure of the oil outlet holes 502 on both sides are tested in two separate tests.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
