[0029] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0030] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0031] See also Figure 1The embodiment of the utility model provides a solenoid valve test fixture for detecting vehicle solenoid valves. The fixture 1 includes a fixture bottom block 11 and a fixture top block 12, wherein the fixture top block 12 is used to install the solenoid valve and is detachably connected to the fixture bottom block 11, so as to detect different types of solenoid valves. It should be noted that the solenoid valve mentioned here is an actuator of an electronic control system, and its main function is to use the electromagnetic force generated by the electric energy flowing through the coil to attract the valve core, thereby controlling the operation of different systems or components. Specifically, it can refer to a suspension system solenoid valve arranged on the chassis of an automobile.

[0032] like Figure 2 As shown, the tooling bottom block 11 includes a bottom block body 111, a first locating pin 112 and a second locating pin 113. Specifically, the bottom block body 111 is a hexahedral structure, with an oil inlet and an oil outlet on the outer surface, and an oil passage for the hydraulic oil to flow therein, so as to detect the physical parameters such as the pressure and flow of the solenoid valve installed on the tooling top block 12. The first locating pin 112 is used to locate the installation position of the tooling top block 12 on the bottom block body 111, is in the shape of a cylindrical column, and is arranged on the outer surface of one side of the bottom block body 111. The second locating pin 113 is also used to locate the installation position of the tooling top block 12 on the bottom block body 111, is in the shape of a prism, and is arranged on the outer surface of the same side of the bottom block body 111 where the first locating pin 112 is arranged. In this embodiment, the first locating pin 112 and the second locating pin 113 both protrude in the direction of the vertical direction of the left side of the bottom block body 111. Preferably, the first positioning pin 112 and the second positioning pin 113 are integrally formed on the bottom block body 111. The structural design of the first positioning pin 112 and the second positioning pin 113 is helpful to locate the installation position of the tooling top block 12 on the bottom block body 111.

[0033] It should be noted that, in consideration of quick disassembly and assembly of the tooling top block 12, the cross-sectional area of ​​the first locating pin 112 is greater than the cross-sectional area of ​​the second locating pin 113. In this way, when the tooling top block 12 is pre-connected to the tooling bottom block 11, since there is a certain movable gap between the second locating pin 113 and the assembly hole of the tooling top block 12, it is beneficial for the first locating pin 112 to be inserted into the tooling top block 12 or to be detached from the tooling top block 12, so as to avoid the tooling top block 12 being scrapped due to the inconvenience of disassembly and assembly of the tooling top block 12. Preferably, the length direction of the first locating pin 112 is parallel to the length direction of the second locating pin 113, and the length of the second locating pin 113 is greater than the length of the first locating pin 112, so as to facilitate the second locating pin 113 to be pre-inserted into the tooling top block 12 for pre-positioning.

[0034] The tooling top block 12 is also a hexahedral structure, with assembly holes matching the first locating pin 112 and the second locating pin 113 on the outer surface, and an oil passage for the hydraulic oil to flow inside, and is installed on the left outer surface of the tooling bottom block 11. It should be noted that in order to reduce the friction force when the tooling top block 12 is installed on the tooling bottom block 11, the ends of the first locating pin 112 and the second locating pin 113 away from the bottom block body 111 are both spherical, specifically, they can be hemispherical. When the tooling top block 12 is installed on the tooling bottom block 11, the ball heads of the first locating pin 112 and the second locating pin 113 are both inserted into the tooling top block 12.

[0035] In this embodiment, considering that the tooling 1 is used frequently, in order to improve its service life, the tooling 1 also includes a guide sleeve 13 embedded in the tooling top block 12. The guide sleeve 13 is used to guide the first locating pin 112 and the second locating pin 113 to pass through the tooling top block 12, and is cylindrical, which is beneficial to improving the wear resistance of the tooling top block 12. It should be noted that a chamfer is provided at the end of the guide sleeve 13. Specifically, the chamfer is arc-shaped, which is not only beneficial to guide the first locating pin 112 and the second locating pin 113 to pass through the tooling top block 12, but also to match the ball head ends on the first locating pin 112 and the second locating pin 113, so as to reduce the resistance of the tooling top block 12 and the tooling bottom block 11 during the assembly process. Preferably, the radius of the chamfer is 2mm to 5mm.

[0036] Generally speaking, according to the different layout positions of the electromagnetic coil and related control components inside the solenoid valve, the solenoid valve of the automobile suspension system can also be divided into external solenoid valves and internal solenoid valves. The difference between the two is that the electromagnetic coil and related control components of the internal solenoid valve are integrated inside the valve body, making the solenoid valve more compact and reducing the space required for external connection and installation.

[0037] like Figure 3 , Figure 5 As shown, in order to facilitate the installation of the external solenoid valve 2, the tool 1 also includes an end cover 14 connected to the tool top block 12 for installing the external solenoid valve 2, and the end cover 14 is detachably connected to the left outer surface of the tool top block 12. Preferably, the end cover 14, the guide sleeve 13 and the tool top block 12 are integrally formed to shorten the changeover time. When it comes to the detection of the external solenoid valve 2, the installation of the external solenoid valve 2 to be detected can be completed by inserting the external solenoid valve 2 into the end cover 14.

[0038] Furthermore, in order to facilitate the installation of the built-in solenoid valve 3, the tool 1 also includes a piston 15, a cover 16 and a tool sleeve 17 connected between the piston 15 and the cover 16 for installing the built-in solenoid valve 3, wherein the piston 15 and the tool sleeve 17 are both embedded in the tool top block 12. When it comes to the inspection of the built-in solenoid valve 3, the built-in solenoid valve 3 is first passed through the tool sleeve 17 and the piston 15 in sequence, and then the cover 16 is installed on one end of the tool sleeve 17, and the installation of the built-in solenoid valve 3 to be inspected can be completed.

The tool bottom block 11 comprises a bottom block body 111 and a first positioning pin 112 and a second positioning pin 113 provided on the outer surface of the bottom block body 111 and used for positioning the tool top block 12.
