Description

Technical Field

[0001] This utility model relates to the field of wheel cylinder sealing testing technology, and more specifically, to a testing machine for testing the sealing strength of hydraulic wheel cylinders in automotive braking systems. Background Technology

[0002] An automotive braking system refers to a series of specialized devices that apply a certain force to certain parts of a car, thereby forcibly braking it to a certain extent. The function of the braking system is to forcibly decelerate or even stop a moving car according to the driver's requirements, to keep a stopped car stable under various road conditions (including on slopes), and to keep a car traveling downhill at a stable speed. The quality of the hydraulic wheel cylinder in the automotive braking system directly affects the braking effect of the system. To ensure that the hydraulic wheel cylinder has a good working effect, a sealing test is usually performed on the hydraulic wheel cylinder after its production is completed.

[0003] When performing a sealing test on a hydraulic wheel cylinder, the test is usually conducted by connecting the test pump to the oil inlet of the hydraulic wheel cylinder and then sealing the other end with a plug. Although this test method is relatively convenient, the plug is placed separately, which makes it very easy for the plug to be forgotten on the hydraulic wheel cylinder after the test is completed. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a hydraulic wheel cylinder sealing strength testing machine for automotive braking systems. Through the reasonable setting of the testing mechanism, the phenomenon of blockages remaining on the hydraulic wheel cylinder is effectively avoided, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic wheel cylinder sealing strength testing machine for automotive braking systems, comprising a housing, a plurality of support rods at the bottom of the housing, handles on both sides of the housing, a test pump at the top of the housing, a plurality of placement rods at the bottom of the test pump, the bottoms of the placement rods being connected to the top of the housing, and a testing mechanism inside the housing.

[0006] In a preferred embodiment, the testing mechanism includes a storage pool, with two connecting plates on the top of the storage pool, a placement plate on the top of the connecting plates, and a hydraulic rod on the rear side of the placement plate.

[0007] In a preferred embodiment, a connecting pipe is provided on the top of one of the placement plates, one end of the connecting pipe is provided with a flexible hose, and the other end of the connecting pipe is provided with a connector.

[0008] In a preferred embodiment, a positioning ring is provided on one side of the connecting pipe, a connecting rope is provided on the positioning ring, and a block is provided at one end of the connecting rope.

[0009] In a preferred embodiment, one end of the hose is connected to the output end of the test pump.

[0010] In a preferred embodiment, the bottom of the hydraulic rod is connected to the top of the connecting plate, and the top of the hydraulic rod is connected to the top of the inner wall of the box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By setting up a testing mechanism, the plug used for sealing is no longer a single component, but can be connected to the positioning ring and connecting pipe via a connecting rope. This connection method allows for clear identification of the plug's position during the separation of the hydraulic wheel cylinder from the testing mechanism after testing, preventing the plug from being left on the hydraulic wheel cylinder. The well-designed testing mechanism allows for simple testing: the hydraulic wheel cylinder is placed on top of two placement plates, the connector within the testing mechanism is connected to the hydraulic wheel cylinder's oil inlet, and the plug is then placed on the other end of the hydraulic wheel cylinder for testing. Furthermore, there is no need for manual application of soapy water during testing; simply activating the hydraulic rod lowers the connecting plate and placement plate into a soapy water reservoir, ensuring full contact between the hydraulic wheel cylinder and the soapy water. This allows for clearer observation of the hydraulic wheel cylinder's surface to determine if the sealing strength meets the standards. These rational design features reduce manual operation steps, further saving manpower and significantly improving the device's practicality. Attached Figure Description

Handles 3, arranged in a U-shape, are provided on both sides of the housing 1 for easy movement of the housing 1. A test pump 4 is located at the top of the housing 1, with several placement rods 5 arranged in a T-shape at the bottom of the test pump 4 for supporting the test pump 4 at corresponding positions on the top of the housing 1. The bottoms of the placement rods 5 are all connected to the top of the housing 1. A testing mechanism is located inside the housing 1.

[0019] As attached Figure 1 , 2 As shown in Figure 3, the testing mechanism includes a storage pool 6. Two connecting plates 7 are provided on the top of the storage pool 6. A placement plate 8 is provided on the top of the connecting plate 7. A hydraulic rod 9 is provided on the rear side of the placement plate 8.

After completion, start the test pump 4 to begin the test. During the test, the hydraulic rod 9 can be activated to move the connecting plate 7 and the placement plate 8 down, sending the hydraulic cylinder located on top of the placement plate 8 into the storage pool 6 to come into contact with soapy water. When in contact, observe whether bubbles appear on the surface of the hydraulic cylinder to more clearly obtain the sealing effect and leakage location of the hydraulic cylinder.
