Description

Technical Field

[0001] This application relates to the field of production testing of automotive parts, and in particular to a height detection mechanism for hydraulic suspension. Background Technology

[0002] Hydraulic mounts are an important automotive component, and their performance and quality have a crucial impact on the vehicle's driving stability and comfort. In the automotive manufacturing and component production process, testing the various performance characteristics and dimensions of hydraulic mounts is a key step in ensuring product quality.

[0003] Currently, existing hydraulic suspension testing technologies mainly focus on inspecting the overall dimensions and structural integrity of the suspension brackets. For example, Chinese patent application "A gauge for testing automotive rear suspension brackets," application number: CN202022797329.9, discloses a device including a base plate. A left support seat and a right support seat are respectively mounted on both sides of the upper end of the base plate. The left support seat is higher than the right support seat. A testing base plate is mounted on the upper end of the base plate in front of the left support seat. A sliding reference strip is mounted on the upper part of the testing base plate, and a handle is mounted at the front end of the reference strip. A hole-position flipping device is mounted on the upper end of the base plate behind the left support seat. A limiting seat is mounted on each side of the upper end of the base plate, both in front and behind the right support seat. A quick clamp is mounted on the outer side of each limiting seat and the outer side of the left support seat.

[0004] In actual automobile production, the height difference between the hydraulic mount inner core and outer shell is also a crucial parameter. The accuracy of this height difference directly affects the sealing performance, cushioning effect, and overall service life of the hydraulic mount. However, existing testing technologies lack specialized high-precision testing mechanisms for this critical dimension, often relying on indirect inference through overall dimensional inspection. This method not only has limited accuracy but also fails to accurately reflect the actual assembly condition between the hydraulic mount inner core and outer shell, making it difficult to meet the high-precision testing requirements of modern automobile manufacturing. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a height detection mechanism for a hydraulic suspension, which can detect the height difference between the inner core and the outer shell of the hydraulic suspension, thus achieving high-precision measurement.

[0006] The technical solution adopted in this application is as follows: a height detection mechanism for a hydraulic suspension includes a mounting base, a limiting ring is provided on the mounting base, a lower detection component is installed inside the limiting ring, the lower detection component includes a lower base ring and a lower detection probe, the lower detection probe is movably mounted on the mounting base, the lower detection probe is connected to an elastic element, the elastic element drives the lower detection probe to a high position of its movement stroke; the hydraulic suspension to be detected is placed on the lower base ring, the limiting ring is sleeved on the outside of the hydraulic suspension, at this time the lower detection probe abuts against the bottom surface of the inner core of the hydraulic suspension.

[0007] Compared with the prior art, the advantages of this application are as follows: First, the testing mechanism is specifically designed for the detection of the height difference between the inner core and outer shell of the hydraulic suspension. By having the lower detection probe abut against the bottom surface of the inner core of the hydraulic suspension and combined with the elastic element driving the lower detection probe to an initial high position, the travel displacement of the lower detection probe can be accurately measured, thereby calculating the height difference between the inner core and outer shell of the hydraulic suspension. This achieves high-precision detection of this dimension, solves the problem that the existing technology cannot directly and accurately measure this height difference, and meets the requirements of modern automobile manufacturing for high-precision inspection of parts.

[0008] Secondly, a limiting ring is installed on the mounting base, which is sleeved on the outside of the hydraulic suspension. This structural design ensures that the hydraulic suspension to be tested is correctly positioned and restrained during placement. During the testing process, the hydraulic suspension will not shift position due to external forces or other factors, ensuring the stability of the testing process. This allows the lower testing probe to accurately contact the bottom surface of the inner core of the hydraulic suspension, thus providing a fundamental guarantee for obtaining accurate and reliable test results and improving the reliability of the test.

[0009] Finally, the lower detection probe is driven by an elastic element to its high position within its stroke. When the hydraulic mount is placed on the lower base ring, the lower detection probe automatically moves downward. This automated inspection process reduces manual operation steps, eliminates the need for frequent manual adjustments to the position and state of the detection probe, significantly improves inspection efficiency, reduces labor costs, and is suitable for batch inspection of hydraulic mounts on automotive parts production lines.

[0010] In some embodiments of this application, the top surface of the lower detection probe is flush with the top surface of the lower base ring as the high position of the lower detection probe's movement stroke. This is a preferred embodiment of this application. This configuration facilitates accurate measurement of the downward displacement of the lower detection probe during the detection process, thereby improving the accuracy of height difference detection and ensuring the reliability of the detection results.

[0011] In some embodiments of this application, the elastic element is a linear spring, which is sleeved outside the lower detection probe and applies a force to the lower detection probe to move upward.

[0012] Using a linear spring as the elastic element and fitting it around the lower detection probe provides a stable and uniform upward force. This design ensures the lower detection probe remains stably elevated under no-load conditions. Furthermore, after hydraulic suspension, the linear spring responds quickly and drives the probe downward, improving detection response speed and stability. In addition, the linear spring is simple in structure, low in cost, highly reliable, and easy to maintain and replace.

[0013] In some embodiments of this application, the application further includes a detection substrate and a column. The column is located on one side of the mounting base. A vertically arranged guide rail is provided on the side of the column. A power cylinder is provided on the top of the column. The detection substrate is movably mounted on the guide rail. The output shaft of the power cylinder is connected to the detection substrate. The power cylinder drives the detection substrate to move up and down along the guide rail.

[0014] By incorporating a detection base plate, columns, guide rails, and a power cylinder, a vertically movable detection base plate system is formed. This structural design allows the upper detection component to move precisely up and down under the drive of the power cylinder, thereby achieving automated detection of the top surface of the hydraulically suspended inner core. The guide rails ensure the accuracy of the detection base plate's movement direction, while the power cylinder provides stable driving force, guaranteeing the stability and repeatability of the detection process and improving the automation and accuracy of the detection.

[0015] In some embodiments of this application, an upper detection component is mounted below the detection substrate, and the upper detection component and the lower detection component are located on the same axis.

[0016] Mounting the upper detection component below the detection base plate and aligning it with the lower detection component on the same axis ensures that both the upper and lower detection probes can inspect the hydraulically suspended core on the same axis. This alignment makes the inspection process more precise, reduces measurement errors caused by positional deviations, and improves the accuracy of the inspection results. At the same time, this structural design simplifies the overall layout of the inspection mechanism and improves space utilization.

[0017] In some embodiments of this application, the upper detection component includes an upper base ring and an upper detection probe. The upper detection probe is movably mounted on the detection substrate. The upper detection probe is connected to a linear spring, which drives the upper detection probe to a low position of its travel stroke.

[0018] The upper detection assembly is designed similarly to the lower detection assembly, employing an upper base ring and an upper detection probe. A linear spring provides downward force, ensuring the upper detection probe remains stably in a low position. This design not only guarantees the stability of the upper detection probe in its initial state but also allows for rapid response to pressure changes in the hydraulically suspended inner core during detection, thus enabling accurate detection of the top surface of the inner core. The use of a linear spring also ensures the stability and reliability of the detection system.

[0019] In some embodiments of this application, the bottom surface of the upper detection probe is flush with the bottom surface of the upper base ring as the low position of the upper detection probe's movement stroke. Similarly, the above scheme is the preferred scheme of this application. During detection, the upper detection probe starts moving from this fixed low position, which can accurately measure its upward stroke displacement, thereby improving the detection accuracy of the hydraulic suspension inner core height and ensuring the accuracy of the detection results.

[0020] In some embodiments of this application, the power cylinder drives the detection base plate and the upper detection component to move downwards until the upper base ring contacts the hydraulic suspension housing. At this time, the upper detection probe abuts against the top surface of the inner core of the hydraulic suspension.

[0021] As the upper detection assembly moves downward, its upper detection probe will first contact the inner core of the hydraulic suspension. The power cylinder continues to drive the upper detection assembly downward, at which point the upper detection probe moves upward relative to the upper base ring under pressure, thus generating a travel stroke.

[0022] The use of a power cylinder enables the automated downward movement of the upper detection component until the upper base ring contacts the hydraulically suspended housing, and the upper detection probe abuts against the top surface of the inner core. This automated process reduces errors from manual operation and improves detection efficiency and consistency. Simultaneously, the precise control capability of the power cylinder ensures the stability and repeatability of the detection plate movement, making the detection results more reliable.

[0023] In some embodiments of this application, the application further includes a transverse moving track, on which the mounting base is movably mounted. A feeding component is provided on one side of the mounting base, and the mounting base engages with the feeding component when it moves on the transverse moving track.

[0024] By setting up a lateral moving track and a feeding component, the mounting base can move along the lateral moving track and dock with the feeding component, realizing the automated feeding process of the testing mechanism. This design not only improves the working efficiency of the testing mechanism and reduces manual intervention, but also allows for seamless docking with other automated equipment on the production line (such as robotic arms, conveyor belts, etc.) to form a complete automated testing production line, suitable for large-scale production environments.

[0025] In some embodiments of this application, the mounting base is connected to a transverse power cylinder, and the operation of the transverse power cylinder drives the mounting base to move along a transverse moving track.

[0026] The use of a transverse power cylinder provides a stable transverse driving force, ensuring the precise movement of the mounting base on the transverse moving track, enabling precise positioning and control, and ensuring that the mounting base can accurately dock with the unloading component.

[0027] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0031] The present application will now be described in detail with reference to the accompanying drawings.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] The height detection mechanism for the hydraulic suspension, as described in Example 1 Figure 1 , Figure 2As shown, the device includes a mounting base 1, on which a limiting ring 4 is provided. A lower detection component is installed within the limiting ring 4. The design of the limiting ring 4 ensures that the hydraulic suspension to be tested is correctly positioned and restrained during placement. During the testing process, the hydraulic suspension will not shift position due to external forces or other factors, ensuring the stability of the testing process. This allows the lower detection probe 7 to accurately abut against the inner core bottom surface of the hydraulic suspension, thus providing a fundamental guarantee for obtaining accurate and reliable test results and improving the reliability of the test.

[0034] The lower detection assembly includes a lower base ring 6 and a lower detection probe 7. The lower detection probe 7 is movably mounted on the mounting base 1 and connected to an elastic element 8. The elastic element 8 drives the lower detection probe 7 to a high position within its travel stroke. The hydraulic suspension to be tested is placed on the lower base ring 6, and a limiting ring 4 is fitted over the hydraulic suspension. At this time, the lower detection probe 7 abuts against the bottom surface of the inner core of the hydraulic suspension. This detection mechanism is specifically designed for detecting the height difference between the inner core and outer shell of the hydraulic suspension. By having the lower detection probe 7 abut against the bottom surface of the inner core of the hydraulic suspension, and combined with the elastic element 8 driving the lower detection probe 7 to an initial high position, the travel displacement of the lower detection probe 7 can be accurately measured. This allows for the calculation of the height difference between the inner core and outer shell of the hydraulic suspension, achieving high-precision detection of this dimension. This solves the problem of the inability to directly and accurately measure this height difference in existing technologies and meets the requirements of modern automobile manufacturing for high-precision component inspection.

[0035] The lower detection probe 7 is driven by the elastic element 8 to a high position within its stroke. When the hydraulic mount is placed on the lower base ring 6, the lower detection probe 7 automatically moves downward. This automated detection process reduces manual operation steps, eliminates the need for frequent manual adjustments to the position and state of the detection probe, greatly improves detection efficiency, reduces labor costs, and is suitable for batch testing of hydraulic mounts on automotive parts production lines.

[0036] Example 2, as Figures 1 to 3 As shown, in some embodiments of this application, the state in which the top surface of the lower detection probe 7 is flush with the top surface of the lower base ring 6 is the high position of the lower detection probe 7's movement stroke. By explicitly setting the specific state of the lower detection probe 7 at the high position, that is, its top surface being flush with the top surface of the lower base ring 6, the detection mechanism has a clear reference position in the initial state. This setting facilitates accurate measurement of the downward stroke displacement of the lower detection probe 7 during the detection process, thereby improving the accuracy of height difference detection and ensuring the reliability of the detection results.

[0037] The elastic element 8 is a linear spring 11, which is sleeved around the lower detection probe 7 and applies an upward force to the lower detection probe 7. Using a linear spring 11 as the elastic element 8 and sleeved around the lower detection probe 7 provides a stable and uniform upward force to the lower detection probe 7. This structural design ensures that the lower detection probe 7 can be stably positioned in a high position when there is no load. Furthermore, after hydraulic suspension, the linear spring 11 can quickly respond and drive the lower detection probe 7 to move downward, improving the detection response speed and stability. In addition, the linear spring 11 has a simple structure, low cost, high reliability, and is easy to maintain and replace.

[0038] This application also includes a detection base plate 2 and a column 3. The column 3 is located on one side of the mounting base 1. A vertically oriented guide rail 9 is provided on the side of the column 3, and a power cylinder 10 is provided on the top of the column 3. The detection base plate 2 is movably mounted on the guide rail 9. The output shaft of the power cylinder 10 is connected to the detection base plate 2, and the operation of the power cylinder 10 drives the detection base plate 2 to move up and down along the guide rail 9. By setting up the detection base plate 2, the column 3, the guide rail 9, and the power cylinder 10, a vertically movable detection base plate 2 system is formed. This structural design allows the upper detection component 12 to achieve precise vertical movement under the drive of the power cylinder 10, thereby realizing automated detection of the top surface of the hydraulic suspension inner core. The setting of the guide rail 9 ensures the accuracy of the movement direction of the detection base plate 2, while the power cylinder 10 provides a stable driving force, ensuring the stability and repeatability of the detection process, and improving the automation and accuracy of the detection.

[0039] An upper detection component 12 is mounted below the detection base plate 2, and the upper detection component 12 is located on the same axis as the lower detection component. This design, where the upper detection component 12 is mounted below the detection base plate 2 and aligned with the lower detection component on the same axis, ensures that the upper and lower detection probes 7 can detect the hydraulically suspended inner core on the same axis. This alignment method makes the detection process more precise, reduces measurement errors caused by positional deviations, and improves the accuracy of the detection results. Simultaneously, this structural design simplifies the overall layout of the detection mechanism and improves space utilization.

[0040] The upper detection assembly 12 includes an upper base ring 13 and an upper detection probe 14. The upper detection probe 14 is movably mounted on the detection base plate 2 and is connected to a linear spring 11. The linear spring 11 drives the upper detection probe 14 to its lowest position within its stroke. The design of the upper detection assembly 12 is similar to that of the lower detection assembly, employing an upper base ring 13 and an upper detection probe 14, with the linear spring 11 providing a downward force to ensure the upper detection probe 14 remains stably in its lowest position. This design not only ensures the stability of the upper detection probe 14 in its initial state but also allows for rapid response to pressure changes in the hydraulically suspended inner core during detection, thereby achieving accurate detection of the top surface of the inner core. The use of the linear spring 11 also ensures the stability and reliability of the detection system.

[0041] The state where the bottom surface of the upper detection probe 14 is flush with the bottom surface of the upper base ring 13 is defined as the low position of the upper detection probe 14's movement stroke. Clearly defining the specific state of the upper detection probe 14 in its low position—that is, its bottom surface being flush with the bottom surface of the upper base ring 13—provides a clear reference position for the detection process. During detection, the upper detection probe 14 moves from this fixed low position, accurately measuring its upward stroke displacement, thereby improving the detection accuracy of the hydraulic suspension inner core height and ensuring the accuracy of the detection results.

[0042] The power cylinder 10 operates, driving the detection base plate 2 and the upper detection assembly 12 downwards until the upper base ring 13 contacts the hydraulic suspension housing. At this point, the upper detection probe 14 abuts against the top surface of the inner core of the hydraulic suspension. During the downward movement of the upper detection assembly 12, its upper detection probe 14 will first contact the inner core of the hydraulic suspension. As the power cylinder 10 continues to operate, driving the upper detection assembly 12 downwards, the upper detection probe 14 moves upwards relative to the upper base ring 13 under pressure, thus generating a travel stroke.

[0043] The use of the power cylinder 10 enables the automated downward movement of the upper detection component 12 until the upper base ring 13 contacts the hydraulic suspension housing, and the upper detection probe 14 abuts against the top surface of the inner core. This automated process reduces errors from manual operation and improves the efficiency and consistency of detection. At the same time, the precise control capability of the power cylinder 10 ensures the stability and repeatability of the movement of the detection substrate 2, making the detection results more reliable.

[0044] like Figure 3As shown, this application also includes a transverse moving track 15, on which the mounting base 1 is movably mounted. A feeding assembly 16 is provided on one side of the mounting base 1. When the mounting base 1 moves along the transverse moving track 15, it engages with the feeding assembly 16. By setting up the transverse moving track 15 and the feeding assembly 16, the mounting base 1 can move along the transverse moving track 15 and engage with the feeding assembly 16, thus realizing an automated feeding process for the testing mechanism. This design not only improves the working efficiency of the testing mechanism and reduces manual intervention, but also allows for seamless integration with other automated equipment on the production line (such as robotic arms, conveyor belts, etc.) to form a complete automated testing production line, suitable for large-scale production environments.

[0045] The mounting base 1 is connected to a transverse power cylinder 17. The operation of the transverse power cylinder 17 drives the mounting base 1 to move along the transverse moving track 15. The use of the transverse power cylinder 17 provides a stable transverse driving force, ensuring the precise movement of the mounting base 1 on the transverse moving track 15, enabling precise positioning and control, and ensuring that the mounting base 1 can accurately dock with the unloading assembly 16.
