When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0052] See also Figure 1 - Fig.10 In an embodiment of the present invention, the electromagnetic force testing and adjusting device of the CDC solenoid valve of the automobile electronically controlled shock absorber comprises:

[0053] The installation frame 1 is provided with a servo press assembly, a detection assembly, a positioning assembly and a support platform 28 in order from top to bottom;

[0054] The servo press assembly is provided with a press head 3, which can be lifted and lowered in the vertical direction. The servo press assembly includes a pressing member 2 provided on the mounting frame 1, an intermediate connecting rod 4 is connected to the action end of the pressing member 2, and a first sliding connection part 401 is formed on the intermediate connecting rod 4, and the first sliding connection part 401 is slidably connected to two guide rods 5 provided on the mounting frame 1;

[0055] One end of the intermediate connecting rod 4 away from the pressing member 2 is connected to the press-fitting ram 3;

[0056] The detection assembly is connected with a measuring head 12, and the measuring head 12 is adapted to the solenoid valve rod to be detected. The detection assembly includes a No. 1 cylinder 6 fixedly mounted on the mounting frame 1, and a follower frame 7 is connected to the telescopic end of the No. 1 cylinder 6, and a No. 2 sliding connection part 701 slidably connected to the guide rod 5 is provided on the follower frame 7, and a displacement sensor 10 is installed on the follower frame 7;

[0057] The detection assembly also includes a detection structure arranged on the follower frame 7, and the detection structure includes a servo drive device 8 fixedly mounted on the follower frame 7. A pressure sensor 9 is connected to the output shaft of the servo drive device 8. The end of the pressure sensor 9 away from the servo drive device 8 is connected to the measuring head 12, and a reference pressure head 11 is provided.

[0058] The servo drive device 8 includes but is not limited to an electric motor drive device, a pneumatic drive device, and a hydraulic drive device.

[0059] When in use, the detection component descends, the reference pressure head 11 fits with the reference surface, and then the measuring head 12 descends and fits with the solenoid valve stem to be tested, and the displacement sensor 10 detects the descending height. The measuring head 12 continues to descend for a fixed height. At this time, the pressure and displacement are monitored. After stabilization, the value of the pressure sensor 9 is obtained, which is the electromagnetic force of the solenoid valve in this state.

[0060] After detection, according to the electromagnetic force test results, the press-fitting head 3 descends under the drive of the pressing part 2 and the intermediate connecting rod 4 to press the bushing, while monitoring the change of electromagnetic force. After reaching the required electromagnetic force, the pressing part 2 stops returning, and then the electromagnetic force is measured again to re-test whether the electromagnetic force meets the requirements.

[0061] The measuring head 12 is disconnected from other components, and the weight of the measuring head 12 itself needs to be subtracted during calibration of the pressure sensor 9 .

[0062] In the prior art, the electromagnetic force of the built-in solenoid valve is guaranteed by the consistency of parts. After installation, the electromagnetic force is fixed and can only be adjusted by adding or removing gaskets at the rear end. It is necessary to measure first and then press-fit and adjust. The above-mentioned setting integrates the electromagnetic force test and adjustment together, and adjustments can be made while measuring, eliminating the influence of various external factors, and adjusting the electromagnetic force to within the qualified range at one time, effectively simplifying the detection and debugging process and reducing the operation workload of technicians.

[0063] See also Fig. 9 The positioning assembly includes: an installation frame 1, a centering member 29, a contact member 30 and a driving assembly, so that under the action of the two centering members 29, the stem of the electromagnetic valve to be tested can be positioned, and because the contact member 30 is far away from the positioning member 27, the flexibility of the positioning member 27 when positioning the stem of the electromagnetic valve to be tested is guaranteed. At the same time, after the stem of the electromagnetic valve to be tested is positioned, it is in a fit state with the arc portion 2902, and the force between the two is very small, thereby avoiding the centering member 29 from acting on the stem of the electromagnetic valve to be tested and causing damage to the stem of the electromagnetic valve to be tested. When the contact member 30 acts on the positioning member 27, the stem of the electromagnetic valve to be tested can be fixed, thereby ensuring the stability of the stem of the electromagnetic valve to be tested during the detection process, as follows:

[0064] The centering members 29 are provided in two groups and are installed on the support platform 28. The two groups of centering members 29 can position the solenoid valve stem under test when they move close to each other, wherein the centering members 29 are provided with arc portions 2902;

[0065] The abutting member 30 is disposed on the mounting frame 1 , and the abutting member 30 cooperates with a positioning member 27 detachably mounted on the stem of the electromagnetic valve to be tested, so as to fix the positioning member 27 .

[0066] When in use, first install the positioning member 27 on the stem of the solenoid valve to be tested. Specifically, the positioning member 27 is connected to the stem of the solenoid valve to be tested by tightening bolts, and then the stem of the solenoid valve to be tested and the positioning member 27 are placed between the two centering members 29. At this time, the positioning member 27 is in contact with the upper surface of the centering member 29. At this time, when the two centering members 29 move towards each other, the arc portions 2902 on the two centering members 29 can cooperate with each other to center the stem of the solenoid valve to be tested and the positioning member 27. In this state, the abutment member 30 does not abut against the positioning member 27, thereby ensuring the flexibility of the movement of the positioning member 27 during the positioning process.

[0067] Specifically, the circumferential radius of the arc portion 2902 is the same as the outer diameter of the solenoid valve stem under test, and the arc portion 2902 has a guide surface tangent to it extending outward, so that after the positioning member 27 and the solenoid valve stem under test are placed, when the two centering members 29 move toward each other, the guide surfaces on the two sets of centering members 29 can be used to guide the solenoid valve stem under test, so that the positioning member 27 and the solenoid valve stem under test are centered, and after the centering member 29 moves into place, the solenoid valve stem under test is in a state of being in contact with the arc portion 2902, and the acting force between the two can be almost negligible.

[0068] After the electromagnetic valve stem is positioned, the abutment member 30 moves downward, and when the abutment member 30 fits the positioning member 27, the positioning member 27 can be fixed on the support platform 28, thereby completing the positioning and fixing of the electromagnetic valve stem.

[0069] Through the above-mentioned arrangement, the two centering members 29 can be used to position the stem of the solenoid valve under test, and because the abutment member 30 is away from the positioning member 27, the flexibility of the movement of the positioning member 27 is guaranteed when the stem of the solenoid valve under test is positioned. At the same time, after the stem of the solenoid valve under test is positioned, it is in a fit with the arc portion 2902, and the force between the two is very small, thereby avoiding the centering member 29 acting on the stem of the solenoid valve under test and causing damage to the stem of the solenoid valve under test. After the abutment member 30 acts on the positioning member 27, the stem of the solenoid valve under test can be fixed, thereby ensuring the stability of the stem of the solenoid valve under test during the detection process, and improving the stability of the electromagnetic force detection when the CDC solenoid valve is energized.

[0070] See also Figure 1 , Figure 6-Figure 10 The driving assembly is connected to the centering member 29 and the abutment member 30, and the driving assembly can drive the centering member 29 and the abutment member 30 to move in sequence. The driving assembly includes: a guide plate 15, a supporting structure, a guide groove and a power member.

[0071] The guide plate 15 is disposed on the installation frame 1, and the guide plate 15 is provided with a connection structure connected to the centering member 29, and a third sliding connection portion 2901 is formed on the centering member 29, and the third sliding connection portion 2901 can slide in the fitting groove 2801 formed on the support platform 28;

[0072] The connection structure includes a transverse shaft 14 disposed on the guide plate 15, and two connecting plates 13 are symmetrically slidably mounted on the transverse shaft 14, and one end of the connecting plate 13 away from the transverse shaft 14 is connected to the centering member 29;

[0073] The connection structure also includes a No. 1 slider 20 connected to the connection plate 13, the No. 1 slider 20 is slidably connected to the No. 2 horizontal groove 1504 provided on the guide plate 15, and the No. 1 slider 20 is connected to the No. 1 sheave 16 through a fitting kit, the fitting kit includes a connecting frame 19 fixedly connected to the No. 1 slider 20 and a No. 2 sheave 17 coaxially rotatably connected to the No. 1 sheave 16, the connecting frame 19 is provided with a retardation groove 1901 in the vertical direction, and the No. 2 sheave 17 can roll in the retardation groove 1901;

[0074] The support structure is arranged on the guide plate 15 and connected to the abutment member 30. The support structure includes a second vertical groove 1503 arranged on the guide plate 15. A second slider 23 is slidably installed in the second vertical groove 1503. The second slider 23 is connected to the abutment member 30.

[0075] The second slider 23 is also slidably connected to a vertical shaft 24 disposed in the second vertical slot 1503. A spring 25 is sleeved on the vertical shaft 24. One end of the spring 25 is connected to the side wall of the second vertical slot 1503, and the other end is connected to the second slider 23.

[0076] A second cam shaft 26 is also provided on one side of the second slider 23, and the second cam shaft 26 is adapted to the power member;

[0077] The guide groove is symmetrically arranged on the guide plate 15, a first groove wheel 16 is arranged in the guide groove, and the guide groove includes a first horizontal groove 1501 and a first vertical groove 1502 arranged on the guide plate 15;

[0078] The power member is disposed on the guide plate 15, and is connected to the first groove wheel 16. When the power member is actuated, the first groove wheel 16 can be driven to move along the guide groove, so that the connection structure and the support structure can be actuated in sequence.

[0079] The power member includes a No. 2 cylinder 22 fixedly mounted on the mounting frame 1, and a lifting plate 21 is connected to the action end of the No. 2 cylinder 22, and a guide portion 2101 is formed on the lifting plate 21, and the guide portion 2101 is slidably connected to the side of the guide plate 15;

[0080] The lifting plate 21 is also symmetrically provided with two inclined grooves 2102 , and the No. 1 cam shaft 18 coaxial with the No. 2 groove wheel 17 can slide in the inclined grooves 2102 .

[0081] In the initial state, the two centering members 29 are in a state of being away from each other, and the spring 25 is in a compressed state, so that the No. 2 slider 23 is at the upper end of the No. 2 vertical groove 1503. At this time, the abutment member 30 and the positioning member 27 are in a separated state, and in this state, the No. 1 groove wheel 16 is at one end of the No. 1 horizontal groove 1501 away from the No. 1 vertical groove 1502, and the No. 1 cam shaft 18 is at the lower end of the inclined groove 2102.

[0082] When performing the positioning and fixing action, the No. 2 cylinder 22 drives the lifting plate 21 to move downward. At this time, since the No. 1 groove wheel 16 can only move along the No. 1 horizontal groove 1501, under the cooperation of the No. 1 cam 18 and the inclined groove 2102, the No. 1 groove wheel 16 will move along the No. 1 horizontal groove 1501, and under the action of the No. 2 groove wheel 17 and the retardation groove 1901, the two No. 1 sliders 20 move closer to each other, so as to drive the two centering parts 29 to move closer to each other, and position the solenoid valve stem body to be tested. After completing the positioning of the solenoid valve rod under test, the No. 1 groove wheel 16 moves to the end of the No. 1 horizontal groove 1501, and the No. 1 cam 18 moves to the end of the inclined groove 2102. At this time, when the lifting plate 21 moves downward, the No. 1 cam 18 can move downward with the inclined groove 2102. When the lifting plate 21 abuts against the No. 2 cam 26, the No. 2 slider 23 is driven to move downward, and the abutting member 30 moves toward the positioning member 27 until the two abut, so that the positioning member 27 is fixed.

[0083] Through the above-mentioned arrangement, it is achieved that when the lifting plate 21 moves, the two positioning members 27 can be first moved closer to each other to center the solenoid valve rod under test, and then the abutment member 30 moves downward to abut against the positioning member 27, thereby completing the fixation of the positioning member 27 and the solenoid valve rod under test. Compared with using multiple driving sources to control the actions of the centering member 29 and the abutment member 30 in sequence, the present application arranges a No. 2 cylinder 22 as a driving source, which can distribute and complete the two actions, thereby improving the integration of the device and simplifying the operating process.
