Description

Technical Field

[0001] This application relates to a hydraulic suspension outer diameter detection mechanism, and more particularly to a hydraulic suspension outer diameter detection mechanism. Background Technology

[0002] In the field of automotive parts inspection, the accurate measurement of the outer diameter of hydraulic mounts, as an important vibration damping component, is crucial for ensuring product quality and performance. Hydraulic mounts are typically used to isolate vibrations between the engine and the vehicle body, and the accuracy of their outer diameter affects installation precision and vibration damping effectiveness. However, current testing equipment on the market mainly focuses on the inspection of automotive bushings, and there is a significant deficiency in the outer diameter measurement of hydraulic mounts.

[0003] While existing bushing inspection equipment can meet the outer diameter inspection requirements of hydraulic suspensions to a certain extent, relevant prior art, such as Chinese patent application "A Quick Inspector for the Inner and Outer Diameter of an Automotive Bushing" (application number: CN202020851505.X), discloses a device including a base, side plates connected to the upper two sides of the base, a bottom plate connected between the two sets of side plates, a magnet at the upper center of the bottom plate, first sliding devices on the upper two sides of the bottom plate, a measuring ruler connected to the upper side between the two side plates, and first sleeves fitted onto the outer two sides of the measuring ruler. A first spring is connected to one end of each first sleeve, and one end of the first spring is connected to the side plate. An outer diameter rod is connected to the lower end of each first sleeve. In this invention, the third spring resets the limiting plate, the second sliding structure moves the bushing, the second spring resets the second sleeve, and the first spring allows the first sleeve to reset after moving outside the measuring ruler. This device facilitates simple and quick bushing inspection operations.

[0004] However, most existing bushing inspection equipment has a relatively simple structure and low level of automation. These devices typically rely on manual operation, resulting in low inspection efficiency and susceptibility to human error, making it difficult to guarantee the accuracy and consistency of inspection results. Furthermore, most of these devices lack automated data recording and analysis capabilities, failing to meet the demands of modern automotive manufacturers for high-efficiency, high-precision inspection. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a hydraulic suspension outer diameter detection mechanism, which realizes automated detection of hydraulic suspension by improving the coordinated work of servo motor and rotary servo motor, and significantly improves detection efficiency and accuracy.

[0006] The technical solution adopted in this application is as follows: an outer diameter detection mechanism for a hydraulic suspension, including a column and a mounting base. A vertically arranged guide rail is provided on the side of the column, and a detection base is installed on the top of the column. The mounting base is installed on the guide rail and connected to a lifting servo motor. A fixing fixture for installing the hydraulic suspension is detachably provided on the mounting base. A rotary servo motor is provided below the mounting base, and a detection device is arranged on the bottom surface of the detection base. The lifting servo motor drives the mounting base to move upward along the guide rail until the hydraulic suspension part enters the detection range of the detection device. The rotary servo motor drives the fixing fixture and the hydraulic suspension to rotate.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, by enhancing the coordinated operation of the servo motor and the rotary servo motor, automatic lifting and rotation of the hydraulic suspension are achieved. Compared with traditional testing equipment that relies on manual operation, this significantly reduces the number of manual intervention steps, avoids testing errors caused by improper or erroneous human operation, and improves the stability and reliability of the testing process. Furthermore, the automated testing mechanism in this technical solution can complete multiple measurements in a short time, significantly improving testing efficiency and helping enterprises accelerate production progress to meet the needs of large-scale production.

[0008] Secondly, the detachable fixing fixtures on the mounting base allow for quick replacement and adjustment of hydraulic mounts of different specifications. This enables the testing mechanism to adapt to hydraulic mount products of various sizes and shapes without requiring large-scale modifications or redesigns of the entire testing equipment, thus improving its versatility and flexibility. In actual production, automobile manufacturers may use multiple models of hydraulic mounts; this technical solution effectively meets these diverse needs and reduces equipment investment costs for enterprises.

[0009] Furthermore, once the hydraulic suspension enters the detection range of the testing device, the rotary servo motor begins operation, detecting not only the outer diameter of the hydraulic suspension but also its circumference. This synchronous detection capability allows the testing mechanism to complete the measurement of multiple key dimensions in a single operation, improving the comprehensiveness and efficiency of the inspection. This continuous data acquisition method provides more comprehensive dimensional information, more accurately reflecting the overall dimensional condition of the hydraulic suspension compared to traditional single-point or limited-point measurements.

[0010] In some embodiments of this application, the detection device is a detection grating, and the detection device includes a transmitter and a receiver arranged opposite to each other, with the transmitter and receiver forming a detection area.

[0011] The above is a preferred embodiment of this application, wherein the transmitter emits a row of dense, parallel laser beams or infrared beams, forming a "light curtain." The receiver is strictly aligned with the transmitter to receive each beam of light from the opposite side. The outer diameter of the hydraulic suspension to be detected = the number of blocked beams × the beam spacing.

[0012] The detection grating measures the outer diameter of the hydraulic mount by blocking the beam between the transmitter and receiver, providing high-precision dimensional data. The grating's high resolution makes the measurement results more accurate, capable of detecting minute dimensional changes. Grating detection is non-contact, causing no physical damage to the hydraulic mount and ensuring the integrity and quality of the measured component. The grating's rapid response and real-time measurement of the hydraulic mount's outer diameter improves detection efficiency.

[0013] In some embodiments of this application, two rows of spaced-apart mounting frames are provided below the detection base, and transmitters and receivers are respectively mounted on the two rows of mounting frames, forming a detection area between the two rows of mounting frames; the transmitters and receivers are movably mounted within the mounting frames.

[0014] The transmitter and receiver are movably mounted within the mounting frame, and their positions can be manually adjusted by the operator. This allows for better matching with hydraulic mounts of different sizes and shapes, improving the adaptability of the detection mechanism. By adjusting the positions of the transmitter and receiver, beam alignment between them can be ensured, guaranteeing measurement accuracy.

[0015] In some embodiments of this application, the mounting base plate has an L-shaped plate structure, and the mounting base plate includes a vertical plate and a horizontal plate. The vertical plate is mounted on a guide rail, the horizontal plate is in a horizontal state, and the rotary servo motor is located below the horizontal plate.

[0016] The L-shaped mounting base provides stable support, ensuring the stability of the hydraulic suspension during the testing process and reducing measurement errors caused by instability in the mounting base structure.

[0017] In some embodiments of this application, a mounting base is provided on the horizontal plate, the top surface of the mounting base is a mounting reference surface, the output shaft of the rotary servo motor passes through the mounting reference surface, the top of the fixing fixture matches the hydraulic suspension to be tested, the bottom of the fixing fixture is a cylindrical structure adapted to the output shaft of the rotary servo motor, and a pin is provided on the fixing fixture; the fixing fixture is sleeved on the output shaft of the rotary servo motor, and the pin passes through the fixing fixture and is inserted into the output shaft of the rotary servo motor.

[0018] The quick-change connection structure allows for rapid replacement of fixed tooling, accommodating different specifications of hydraulic mounts and improving the equipment's versatility and flexibility. The quick-change design enables operators to quickly change tooling, reducing equipment setup time and increasing production efficiency.

[0019] In some embodiments of this application, inductive sensors for detecting whether a hydraulic suspension is installed are arranged on both sides of the cross plate.

[0020] The inductive sensor can automatically detect whether the hydraulic suspension is correctly installed on the fixed fixture, avoiding measurement errors caused by improper installation of the product and improving the reliability of the detection.

[0021] In some embodiments of this application, the fixed fixture is provided with a product identifier, and a fixture identification sensor is installed on one side of the mounting base. The fixture identification sensor is used to detect the product identifier on the fixed fixture.

[0022] The tooling identification sensor can automatically recognize product markings on fixed tooling, thereby determining the product type of the hydraulic suspension to be inspected and matching it with pre-stored dimensional data standards, improving the automation level of the inspection. The automatic identification function reduces measurement deviations caused by human error, improving the accuracy and consistency of the inspection.

[0023] In some embodiments of this application, the fixing fixture is located directly below the detection area. This placement ensures that the hydraulic suspension accurately enters the detection area during the detection process, improving the accuracy and reliability of the detection. This layout also ensures that the hydraulic suspension remains in the optimal detection position throughout rotation, guaranteeing the stability of the measurement data.

[0024] In some embodiments of this application, the lifting servo motor is disposed on the top surface of the column. Disposing the lifting servo motor on the top surface of the column makes the entire detection mechanism more compact and saves space.

[0025] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0029] The present application will now be described in detail with reference to the accompanying drawings.

[0030] 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.

[0031] The outer diameter detection mechanism for the hydraulic suspension, as described in Example 1 Figure 1 , Figure 2 As shown, the system includes a column 1 and a mounting base. A vertically aligned guide rail 3 is provided on the side of the column 1, and a testing base 4 is mounted on the top of the column 1. The mounting base is mounted on the guide rail 3 and connected to a lifting servo motor 5. A detachable fixture 6 for mounting hydraulic suspensions is mounted on the mounting base. The fixture 6 can be quickly replaced and adjusted according to different specifications of hydraulic suspensions. This allows the testing mechanism to adapt to hydraulic suspension products of various sizes and shapes without requiring large-scale modifications or redesigns of the entire testing equipment, improving the equipment's versatility and flexibility. In actual production, automobile manufacturers may use various models of hydraulic suspensions; this technical solution can well meet this diverse need and reduce the company's equipment investment costs.

[0032] A rotary servo motor 7 is installed below the mounting base, and a detection device 8 is arranged on the bottom surface of the detection base 4. A lifting servo motor 5 drives the mounting base to move upwards along the guide rail 3 until the hydraulic suspension portion enters the detection range of the detection device 8. The rotary servo motor 7 drives the fixed fixture 6 and the hydraulic suspension to rotate. Through the coordinated operation of the lifting servo motor 5 and the rotary servo motor 7, automatic lifting and rotation of the hydraulic suspension are achieved. Compared with traditional detection equipment that relies on manual operation, this significantly reduces the need for manual intervention, avoids detection errors caused by improper or incorrect human operation, and improves the stability and reliability of the detection process. Furthermore, the automated detection mechanism in this technical solution can complete multiple measurements in a short time, significantly improving detection efficiency and helping enterprises accelerate production progress to meet the needs of large-scale production.

[0033] Once the hydraulic suspension enters the detection range of the detection device 8, the rotary servo motor 7 starts working, detecting not only the outer diameter of the hydraulic suspension but also its circumference. This synchronous detection capability allows the detection mechanism to complete the measurement of multiple key dimensions in a single operation, improving the comprehensiveness and efficiency of the detection. This continuous data acquisition method provides more comprehensive dimensional information, and compared to traditional single-point or limited-point measurements, it can more accurately reflect the overall dimensional condition of the hydraulic suspension.

[0034] Example 2, as Figures 1 to 2 As shown, the detection device 8 is a detection grating, comprising a transmitter and a receiver arranged opposite each other, forming a detection area between them. The above is a preferred embodiment of this application, wherein the transmitter emits a row of dense, parallel laser beams or infrared beams, forming a "light curtain." The receiver is strictly aligned with the transmitter, receiving each beam of light from the opposite side. The outer diameter of the hydraulic suspension to be detected = the number of blocked beams × the beam spacing.

[0035] The detection grating measures the outer diameter of the hydraulic mount by blocking the beam between the transmitter and receiver, providing high-precision dimensional data. The grating's high resolution makes the measurement results more accurate, capable of detecting minute dimensional changes. Grating detection is non-contact, causing no physical damage to the hydraulic mount and ensuring the integrity and quality of the measured component. The grating's rapid response and real-time measurement of the hydraulic mount's outer diameter improves detection efficiency.

[0036] Below the detection base 4, two rows of spaced-apart mounting frames 12 are arranged. Each row of frames 12 houses a transmitter and a receiver, respectively, forming the detection area between the two rows of frames 12. The transmitter and receiver are movably mounted within the mounting frames 12. This movability allows the operator to manually adjust their positions, better accommodating hydraulic mounts of different sizes and shapes, thus improving the adaptability of the detection mechanism. Adjusting the positions of the transmitter and receiver ensures beam alignment between them, guaranteeing measurement accuracy.

[0037] The mounting base has an L-shaped plate structure, including a vertical plate 13 and a horizontal plate 14. The vertical plate 13 is mounted on the guide rail 3, and the horizontal plate 14 is in a horizontal state. The rotary servo motor 7 is located below the horizontal plate 14. The L-shaped mounting base provides stable support, ensuring the stability of the hydraulic suspension during the testing process and reducing measurement errors caused by instability in the mounting base structure.

[0038] A mounting base 15 is provided on the horizontal plate 14. The top surface of the mounting base 15 is the mounting reference surface. The output shaft 16 of the rotary servo motor 7 extends through the mounting reference surface. The top of the fixing fixture 6 matches the hydraulic suspension to be tested, and the bottom of the fixing fixture 6 is a cylindrical structure adapted to the output shaft 16 of the rotary servo motor 7. A pin 17 is provided on the fixing fixture 6. The fixing fixture 6 is sleeved on the outside of the output shaft 16 of the rotary servo motor 7, and the pin 17 passes through the fixing fixture 6 and is inserted into the output shaft 16 of the rotary servo motor 7. The quick-change connection structure allows the fixing fixture 6 to be quickly replaced to adapt to different specifications of hydraulic suspensions, improving the versatility and flexibility of the equipment. The quick-change structure design allows operators to quickly complete the tooling change, reducing equipment adjustment time and improving production efficiency.

[0039] The horizontal plate 14 is equipped with inductive sensors 18 on both sides for detecting whether the hydraulic suspension is installed. The inductive sensors 18 can automatically detect whether the hydraulic suspension is correctly installed on the fixed fixture 6, avoiding measurement errors caused by the product not being installed properly, and improving the reliability of the detection.

[0040] The fixed fixture 6 is equipped with a product identification mark, and a fixture identification sensor 19 is installed on one side of the mounting base 15. The fixture identification sensor 19 is used to detect the product identification mark on the fixed fixture 6. The fixture identification sensor 19 can automatically identify the product identification mark on the fixed fixture 6, thereby determining the product type of the hydraulic suspension to be inspected, matching it with pre-stored dimensional data standards, and improving the automation level of the inspection. The automatic identification function reduces measurement deviations caused by human identification errors, and improves the accuracy and consistency of the inspection.

[0041] The fixing fixture 6 is located directly below the detection area. This location ensures that the hydraulic suspension accurately enters the detection area during the detection process, improving the accuracy and reliability of the detection. This layout allows the hydraulic suspension to remain in the optimal detection position throughout rotation, guaranteeing the stability of the measurement data.

[0042] The lifting servo motor 5 is mounted on the top surface of the column 1. Mounting the lifting servo motor 5 on the top surface of the column 1 makes the entire detection mechanism more compact and saves space.

It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
