After assembly, they require comprehensive testing to ensure stability and long-term reliability in subsequent applications. In industrial production processes, there is a need to improve the convenience and speed of solenoid valve testing.

[0003] Currently, the testing of solenoid valves usually adopts a single-station testing method. During the testing process, only one test item of a single solenoid valve can be monitored, resulting in low testing efficiency.

[0026] Example Reference Figure 1 and Figure 2 As shown, this embodiment provides a multi-station solenoid valve testing device, including a base 1, a rotary drive 2, a quick-change turntable 3, and a testing station. A worktable 11 is provided on the base 1, and the rotary drive 2 is installed inside the base 1. The rotary drive 2 can be a rotary motor.

[0027] Reference Figure 2 As shown, the quick-change turntable 3 is detachably mounted on the workbench 11 and is connected to the rotary drive component 2, specifically to the drive shaft 21 of the rotary motor, which drives the quick-change turntable 3 to rotate. The quick-change turntable 3 includes multiple installation stations 31 arranged around its axis. Each installation station 31 corresponds to a first test flow channel 32, extending to the side wall of the quick-change turntable 3. The first test flow channel 32 extends from the bottom of the installation station 31 to the side wall of the quick-change turntable 3. In this embodiment, there are a total of 6 installation stations 31, correspondingly making the outer wall contour of the quick-change turntable 3 hexagonal, giving the quick-change turntable 3 6 contact surfaces 33, so that each installation station 31 corresponds to one contact surface 33 of the quick-change turntable 3 via a set of first test flow channels 32. Since different types of solenoid valves 6 have different numbers of passages and opening positions, only the corresponding quick-change turntable 3 needs to be replaced to test different types of solenoid valves 6.

[0028] Reference Figure 2 and Figure 3As shown, multiple testing stations are arranged around the outer periphery of the quick-change turntable 3, i.e., a total of 6 testing stations are provided in this embodiment. Each testing station is equipped with a corresponding testing component 4; the testing component 4 includes a translation drive 41 and a testing head 42; the translation drive 41 is mounted on the worktable 11, and the testing head 42 is connected to the translation drive 41; the testing head 42 has a second test flow channel 43 extending to the end face of the testing head 42; the translation drive 41 can be a cylinder. In this embodiment, each testing station is used to test different test items of the solenoid valve 6, i.e., each testing head 42 is connected to a corresponding testing unit to realize the testing of the corresponding test item. Therefore, during testing, different test items of different solenoid valves 6 can be tested simultaneously, and the testing of 6 different test items of 6 solenoid valves 6 can be completed by rotating the quick-change turntable 3 six times.

[0029] It should be noted that in other embodiments, the number of installation stations 31 can also be set to different numbers, such as N installation stations, where N≥2. Correspondingly, the number of quick-change turntables 3 is also set to N. Each installation station 31 detects different test items, and the quick-change turntables 3 can be rotated N times to complete the detection of N different test items of N solenoid valves 6.

[0030] During testing, the translation drive 41 drives the test head 42 to move until it abuts against the side wall of the quick-change turntable 3, thereby connecting the first test channel 32 and the second test channel 43 and positioning the quick-change turntable 3. When disassembling or rotating the quick-change turntable 3, the translation drive 41 drives the test head 42 to move so that it separates from the quick-change turntable 3, facilitating disassembly and rotation.

[0031] The multi-station solenoid valve testing device provided in this embodiment adopts a combination of multiple installation stations 31 and multiple testing stations, which can realize the simultaneous testing of multiple solenoid valves 6 for multiple test items. Different solenoid valves 6 can be switched for different test items by rotating the quick-change turntable driven by the rotary drive 2. Furthermore, the testing head 42 is driven by the translation drive 41, which facilitates pressing against the quick-change turntable 3 during testing and separating from the quick-change turntable 3 during switching. It provides positioning for the quick-change turntable 3 during testing and facilitates the rotation of the quick-change turntable 3 during switching. When testing different types of solenoid valves 6, only the quick-change turntable 3 needs to be replaced. Overall, the testing efficiency is improved, and it is also convenient to test different types of solenoid valves 6.

[0032] Specifically, refer to Figure 1 As shown, the base 1 is provided with a housing 12, which shields part of the detection station to form protection.

[0033] Specifically, refer to Figure 7As shown, the bottom of the quick-change turntable 3 is provided with a mounting hole 34 for accommodating the drive shaft 21 of the rotary drive component 2, and a slot 35 for transmission engagement with the drive shaft 21 of the rotary drive component 2. This facilitates quick disassembly and assembly, improving efficiency and convenience.

[0034] Specifically, refer to Figure 11 As shown, a sealing ring 36 is provided on the abutment surface 33. The sealing ring 36 is installed on the blind hole of the abutment surface 33, so that the sealing ring 36 is located at the end of the first test flow channel 32. When the detection head 42 abuts against the abutment surface 33 of the quick-change turntable 3, it abuts against the sealing ring 36, thereby improving the sealing performance between the first test flow channel 32 and the second test flow channel 43. It can also compensate for the slight angular deviation that occurs during the rotation of the quick-change turntable 3 and reduce the accuracy required for docking.

[0035] Specifically, refer to Figure 8 and Figure 9 As shown, the detection head 42 includes a connecting block 44 and a connecting plate 45, the connecting plate 45 being connected to the translation drive component 41; the connecting block 44 and the connecting plate 45 are detachably connected; the second test flow channel 43 is located within the connecting block 44. This allows for easy replacement of the corresponding connecting block 44 when dealing with different types of solenoid valves 6.

[0036] Specifically, the connecting block 44 includes a connecting portion 442 and a protrusion 441; the protrusion 441 protrudes outward from the side of the connecting portion 442; the connecting portion 442 is connected to the connecting plate 45 via a connector; the second test flow channel 43 extends from one end face of the protrusion 441 to the other end face. This facilitates the provision of an interface 443 corresponding to the second test flow channel 43 on the protrusion 441, and the connection between the interface 443 and the corresponding detection unit is achieved via a quick-connect connector 46.

[0037] Specifically, an installation station 31 has multiple independent first test channels 32; a detection head 42 has multiple independent second test channels 43; the first test channels 32 and the second test channels 43 correspond one-to-one. The number of first test channels 32 and second test channels 43 can be designed according to the structural type of the solenoid valve 6.

[0038] Specifically, refer to Figure 4 As shown, the installation station 31 is provided with an installation groove 37 for accommodating the valve to be tested. (Refer to...) Figure 1 and Figure 2As shown, it also includes a top clamping assembly 5; the top clamping assembly 5 includes a mounting bracket 51, a vertical drive component 52, and a pressure plate 53; the mounting bracket 51 is mounted on the worktable surface 11; the vertical drive component 52 is connected to the mounting bracket 51, and the pressure plate 53 is connected to the vertical drive component 52, with the pressure plate 53 located above the quick-change turntable 3. The solenoid valve 6 is positioned by the cooperation of the mounting slot 37 and the pressure plate 53, ensuring stability during the testing process.

[0039] Specifically, refer to Figure 12 As shown, the pressure plate 53 is provided with a flexible pressing mechanism 54; the flexible pressing mechanism 54 includes a cylinder 541, an elastic element 542, and a top ball 543; the cylinder 541 is connected to the pressure plate 53, the elastic element 542 is connected to the cylinder 541 and abuts against the top ball 543, the top ball 543 is movably installed inside the cylinder 541, and the elastic element 542 has elastic potential energy to move the top ball 543 toward the direction of the quick-change turntable 3. The elastic element 542 is a spring, which pushes the top ball 543 to press the solenoid valve 6, which can avoid the solenoid valve 6 being damaged by excessive pressure, and also avoid leakage caused by insufficient pressure.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
