[0059] The following details the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0060] Figure 1 is the structural schematic view of the detection device for the concentricity of the shock absorber solenoid valve seat according to an embodiment of the present invention, Figure 2 is the structural schematic view of the rotating assembly in the detection device for the concentricity of the shock absorber solenoid valve seat according to an embodiment of the present invention,Figure 3 It is a cross-sectional view of the hollow column in the detecting device for the concentricity of the shock absorber solenoid valve seat according to an embodiment of the present utility model. In Figures 1 to 3 this, the detecting device may include a hollow column 5, a clamping assembly 10, a light source assembly 14, and a vision detecting assembly 22.

[0061] The clamping assembly 10 is arranged at one end of the hollow column 5 and is used for clamping and fixing the open end of the oil storage cylinder 1. The light source assembly 14 is arranged inside the hollow column 5, and the output end of the light source assembly 14 is close to one end of the hollow column 5 and is used for cooperating with the clamping assembly 10 to emit irradiation light into the interior of the oil storage cylinder 1. The vision detecting assembly 22 is perpendicularly distributed with the clamping assembly 10, and the vision detecting assembly 22 is used to face the solenoid valve seat 2 on the oil storage cylinder 1 to detect the concentricity of the through hole 3 on the oil storage cylinder 1 and the solenoid valve seat 2.

[0062] When it is necessary to detect the concentricity of the solenoid valve seat 2 and the through hole 3 on the oil storage cylinder 1 of the shock absorber, the clamping assembly 10 is used to clamp and fix the open end of the oil storage cylinder 1, and at the same time, the solenoid valve seat 2 is made to face the vision detecting assembly 22. Specifically, the end of the solenoid valve seat 2 far from the oil storage cylinder 1 is made to face the vision detecting assembly 22. Then the light source assembly 14 is started to emit irradiation light. Since the output end of the light source assembly 14 is close to one end of the hollow column 5, that is, close to the open end of the oil storage cylinder 1, the light source assembly 14 can emit irradiation light into the interior of the oil storage cylinder 1 to illuminate the interior of the oil storage cylinder 1. Finally, the vision detecting assembly 22 is started to perform visual detection on the solenoid valve seat 2 and the through hole 3 inside it. Since the interior of the oil storage cylinder 1 is irradiated, the edge of the through hole 3 on the side wall of the oil storage cylinder 1 becomes clearly visible, and thus it is convenient to detect the concentricity of the solenoid valve seat 2 and the through hole 3.

[0063] The relationship between the traditional shock absorber solenoid valve seat 2 and the through hole 3 on the side wall of the oil storage cylinder 1 can be as shown in Figure 5 and Figure 6 shown. For the concentricity detection of the two, generally, the method of manual holding or vision camera detection is adopted. However, the manual detection has low efficiency and large errors, and the vision camera detection cannot clearly identify the bottom through hole 3 of the solenoid valve seat 2, resulting in low detection accuracy. In this embodiment of the present utility model, by adopting the method of irradiating along the interior of the oil storage cylinder 1 with the light source assembly 14, the vision detecting assembly 22 can clearly identify the edge of the through hole 3, and the detection accuracy of the concentricity of the solenoid valve seat 2 and the through hole 3 can be improved to ensure the performance of the shock absorber. In addition, the light source assembly 14 is arranged inside the hollow column 5. On the one hand, it reduces the difficulty of irradiation and improves the convenience of irradiation; on the other hand, it will not interfere with the visual detection of the vision detecting assembly 22, ensuring the stability and reliability of the visual detection.

[0064] In this embodiment of the present utility model, the specific form of the clamping assembly 10 may include, but is not limited to, the commonly used expansion sleeve in machine tools known to those skilled in the art. In addition, the clamping assembly 10 may further include two relatively arranged semi-circular plates, and the distance between the two semi-circular plates is adjusted by bolts to clamp and fix the oil storage cylinder 1, etc.

[0065] In this embodiment of the present utility model, the inner hollow shaft diameter of the hollow column 5 may be greater than the shaft diameter of the oil storage cylinder 1, so that the open end of the oil storage cylinder 1 can extend into the interior of the hollow column 5, thereby improving the effect of the light source assembly 14 irradiating the interior of the oil storage cylinder 1.

[0066] In this embodiment of the present utility model, as Figures 1 - 4 shown, the detection device may further include a support base 18, a base 4, a bearing 15, and a rotating assembly. Specifically, the base 4 may include a circular hole.

[0067] The base 4 is arranged on the top of the support base 18, and a circular hole is formed in the base 4. The bearing 15 is arranged inside the circular hole, the outer ring of the bearing 15 is fixedly connected to the inner wall of the circular hole, and the side wall of the hollow column 5 is fixedly connected to the inner ring of the bearing 15. The rotating assembly is arranged on the base 4, and the rotating assembly is used to drive the hollow column 5 to rotate.

[0068] After the oil storage cylinder 1 is clamped by the clamping assembly 10, the rotating assembly is started. The rotating assembly drives the hollow column 5, the clamping assembly 10, and the oil storage cylinder 1 clamped and fixed on the clamping assembly 10 to rotate synchronously, so that the solenoid valve seat 2 on the oil storage cylinder 1 can rotate to face the visual detection assembly 22 exactly, further improving the convenience and accuracy of concentricity detection. In addition, generally two solenoid valve seats 2 are arranged on the oil storage cylinder 1. After the concentricity between one solenoid valve seat 2 and the corresponding through hole 3 is detected. The rotating assembly is started to rotate the oil storage cylinder 1, so that the other solenoid valve seat 2 rotates to face the visual detection assembly 22 exactly, and then the concentricity between the other solenoid valve seat 2 and the corresponding through hole 3 can be detected. By using the method of driving the oil storage cylinder 1 to rotate by the rotating assembly, there is no need to manually change the orientation of the solenoid valve seat 2, thereby improving the efficiency of concentricity detection.

[0069] In this embodiment of the present utility model, as Figures 2 - 4 shown, the rotating assembly may include a connecting seat 8, a servo motor 7, an annular plate 9, a runner 11, and a synchronous belt 12. Specifically, the annular plate 9 may include a first belt groove 16, and the runner 11 may include a second belt groove 17.

[0070] The connecting seat 8 is arranged on the top of the base 4, and the servo motor 7 is arranged on the connecting seat 8. The ring plate 9 is rotatably arranged at the other end of the hollow column 5, and a first belt groove 16 is formed on the outer side wall of the ring plate 9. The runner 11 is fixedly sleeved on the output end of the servo motor 7, and a second belt groove 17 is formed on the outer side wall of the runner 11. The synchronous belt 12 is sleeved on the first belt groove 16 and the second belt groove 17 for driving cooperation with the ring plate 9 and the runner 11.

[0071] When it is necessary to drive the hollow column 5 to rotate, the servo motor 7 is started. The ring plate 9, the runner 11 and the synchronous belt 12 cooperate to form a transmission structure. When the runner 11 rotates, the ring plate 9 and the hollow column 5 can be driven to rotate synchronously. By adopting this way of driving the hollow column 5 to rotate with this transmission structure, on the one hand, the stability of the rotation of the hollow column 5 is ensured, and on the other hand, it can also make way for the light source assembly 14.

[0072] In this embodiment of the present invention, as Figure 2 and Figure 3 shown, the light source assembly 14 may include a support plate 6 and an irradiation lamp 13.

[0073] The support plate 6 is arranged on the top of the support seat 18 and is located at one end of the ring plate 9 away from the hollow column 5. The irradiation lamp 13 is arranged on the side wall of the support plate 6 close to the ring plate 9, and the output end of the irradiation lamp 13 extends along the inside of the hollow column 5.

[0074] The irradiation lamp 13 is externally connected to a power supply and is located inside the hollow column 5, and can effectively emit light / irradiation light along the open end of the oil storage cylinder 1 to the inside of the oil storage cylinder 1.

[0075] In this embodiment of the present invention, as Figure 1 shown, the vision detection assembly 22 may include a first support column 21 and a first detection camera 20.

[0076] The first support column 21 is arranged on the top of the support seat 18, and the first detection camera 20 is arranged on the top of the first support column 21.

[0077] When the solenoid valve seat 2 rotates to be directly opposite to the first detection camera 20, the first detection camera 20 can identify and detect the solenoid valve seat 2 and the corresponding through hole 3, and then determine whether they are concentric / coaxial.

[0078] In this embodiment of the present invention, as Figure 1 shown, the detection device may further include a second support column 23 and a second detection camera 24.

[0079] The second support column 23 is arranged on the top of the support seat 18 and is directly opposite to the base 4, and the second detection camera 24 is arranged on the top of the second support column 23.

[0080] When the clamping assembly 10 clamps and fixes the oil storage cylinder 1, the second detection camera 24 can face the closed end of the oil storage cylinder 1 and synchronously detect the oil storage cylinder 1 and the two solenoid valve seats 2. Specifically, it can detect the perpendicularity of the axis of the solenoid valve seat 2 to the axis of the oil storage cylinder 1, etc. Therefore, the second detection camera 24 can further improve the detection accuracy and ensure the performance of the shock absorber.

[0081] In this embodiment of the present utility model, as Figure 1 shown, the detection device may further include a pulley, a sliding seat 19 and a driving assembly 26.

[0082] The slide rail 25 is arranged on the top of the support seat 18. The sliding seat 19 is slidably connected to the slide rail 25, and the base 4 is arranged on the top of the sliding seat 19. The driving assembly 26 is connected to the sliding seat 19 and is used to drive the sliding seat 19 to slide along the slide rail 25.

[0083] Considering that the two solenoid valve seats 2 on the oil storage cylinder 1 are arranged in a staggered manner and there are various sizes of oil storage cylinders 1, it is necessary to start the driving assembly 26 to adjust the position of the solenoid valve seat 2. The driving assembly 26 drives the sliding seat 19 to slide along the slide rail 25, and the oil storage cylinder 1 moves axially synchronously to drive the solenoid valve seat 2 to move synchronously until it faces the first detection camera 20. By adopting this method, the versatility and convenience of detection are effectively improved.

[0084] In this embodiment of the present utility model, for the specific form of the driving assembly 26, it includes but is not limited to cylinders, ball screws, etc. known to those skilled in the art.

[0085] In this embodiment of the present utility model, considering the stability of the movement of the base 4, the number of the slide rails 25 may be as Figure 1 shown. Specifically, in Figure 1 it, the number of the slide rails 25 may include two. Specifically, the two slide rails 25 are distributed in parallel, and the sliding seat 19 is slidably connected to the two slide rails 25.

[0086] In this embodiment of the present utility model, as Figure 1 shown, the support seat 18 may include two sets of detection devices, and the two sets of detection devices are symmetrically distributed.

[0087] In this embodiment of the present utility model, as Figure 1 shown, the vision detection assembly 22 may further include a partition 27. Specifically, the partition 27 is arranged on the top of the support seat 18 and is opposite to the first detection camera 20. Specifically, the partition 27 can effectively reduce the detection interference of the first detection camera 20 and further improve the detection accuracy.

[0088] Through the above technical solution, the detection device for the concentricity of the shock absorber solenoid valve seat 2 provided by the present utility model clamps and fixes the open end of the oil storage cylinder 1 through the clamping assembly 10, and at the same time makes the solenoid valve seat 2 face the vision detection assembly 22; start the light source assembly 14 to illuminate the inside of the oil storage cylinder 1 and the through hole 3 on the side wall of the oil storage cylinder 1, and then start the vision detection assembly 22 to perform concentricity identification and detection on the solenoid valve seat 2 and the through hole 3. By adopting the detection method of cooperating the light source assembly 14 and the vision detection assembly 22, on the one hand, it can effectively improve the recognition degree of the vision detection assembly 22 for the through hole 3, that is, improve the detection accuracy of the concentricity and ensure the performance of the shock absorber; on the other hand, the irradiation position of the light source assembly 14 will not interfere with the vision detection of the vision detection assembly 22, ensuring the stability and reliability of the vision detection.
