Description

Technical Field

[0001] The invention belongs to the technical field of damper assembly, relates to a technology for realizing the assembly and power display requirements of multiple types of dampers, and specifically relates to a damper assembly system. Background Art

[0002] In the suspension system of motorcycles or electric vehicles, the shock absorber (also known as damper) is a key component. Its main function is to absorb and reduce the impact and vibration caused by uneven roads, thereby improving riding comfort and vehicle handling stability. Common shock absorbers mainly absorb vibration energy through hydraulic or pneumatic methods. Hydraulic shock absorbers use the flow and damping effect of liquid in the cylinder to absorb vibration energy, while pneumatic shock absorbers achieve the same effect by compressing and expanding gas.

[0003] Mechanical dynamometer is a process of directly measuring force or torque through mechanical structure and lever principle, which is often used for static or low-frequency testing. The main purpose of dynamometer detection is to test the performance of the damper under different working conditions through reciprocating motion, especially the change of the damping force of the damper with displacement. If the axis of the detection unit and the pull rod assembly are not aligned, the entire force transmission process will be affected by the lateral force, resulting in inaccurate measured data. The specific manifestations are:

[0004] Nonlinear force transmission: Due to the misalignment of the axis, lateral force is introduced into the loading force, and the force on the damper is no longer a single axial force. The lateral force will cause fluctuations in the measurement results, and cannot correctly reflect the true mechanical properties of the damper, resulting in nonlinear errors in the force-displacement curve.

[0005] Data consistency issues: In multiple rounds of testing, axis misalignment in different assembly states may lead to differences in test results, affecting the repeatability and consistency of data. Even for the same damper, axis misalignment may lead to different test results each time, making it difficult to ensure product quality consistency. Summary of the invention

DETAILED DESCRIPTION

[0092] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0093] See also Figures 1 to 11 As shown, the specific embodiments provided by the present invention are as follows:

[0094] like Figures 1 to 5 As shown, the first embodiment of the present invention provides a damper assembly system, comprising:

[0095] A frame 1 having a work surface 101;

[0096] A material feeding unit 2 having a conveying component 201 and a tooling component 202;

[0097] The tooling assembly 202 is connected to the conveying assembly 201;

[0098] A plurality of assembly units having a storage component 302 and a clamping component 301;

[0099] A plurality of the storage components 302 are arranged along the conveying route of the conveying component 201 to store various accessories of the damper;

[0100] Each of the clamping components 301 is disposed on one side of each of the storage components 302 to clamp the corresponding accessory to the tooling component 202;

[0101] A detection unit having a power indicator drive assembly 801 and a power indicator transmission assembly 802;

[0102] Wherein, the power indicator transmission assembly 802 is connected with a power indicator detection clamp;

[0103] The power indicator drive assembly 801 is connected to the power indicator transmission assembly 802 to drive the power indicator transmission assembly 802 to drive the power indicator detection clamp to clamp the damper rod assembly and move back and forth;

[0104] A fixed axis unit having a first fixed axis component 9 and a second fixed axis component 10;

[0105] Wherein, the first fixed axis assembly 9 is configured to be in sliding contact with the end of the power indicator transmission assembly 802, and constrain the end of the power indicator transmission assembly 802 to move back and forth along the displacement axis M;

[0106] Furthermore, the second fixed axis assembly 10 is configured to contact the pull rod assembly and guide the axis of the pull rod assembly to be coaxial with the displacement axis M.

[0107] In this embodiment, the frame 1 of the damper assembly system is designed as a frame structure, and its main function is to provide a solid and stable support for the entire assembly system. The frame structure enables the system to carry various components such as the feeding unit 2, the assembly unit, the conversion unit and the detection unit, and ensures that these components maintain accurate positioning and reliable operation during operation.

[0108] The feeding unit 2 is composed of a conveying assembly 201 and a tooling assembly 202. The conveying assembly 201 is arranged on the work surface 101 in a circular line. This design can effectively optimize the assembly process, reduce the moving distance of the workpiece, and improve the overall assembly efficiency. The tooling assembly 202 can be accurately displaced along the circular line by connecting to the conveying assembly 201 to ensure that the necessary assembly and inspection operations are performed at each station.

[0109] The assembly unit includes a storage component 302 and a clamping component 301. The storage component 302 is arranged along a ring line and is used to store various accessories of the damper, such as oil seals, gaskets, dust covers, etc. These accessories can be picked up by the clamping component 301 at any time according to the needs of the assembly steps and installed on the tooling component 202 to ensure the continuity and efficiency of the assembly process.

[0110] On the basis of the above, in the dynamometer detection system, accurate force transmission and motion control are the core requirements to ensure the accuracy of the detection results. The design of the fixed axis unit is to solve the problem of axis misalignment between the detection unit and the damper rod assembly during movement, which will cause a series of technical obstacles, including the following aspects:

[0111] Lateral force and uneven force transmission caused by axis misalignment: When the axes of the indicator drive assembly and the pull rod assembly are not coaxial, the force transmission path will deviate from the ideal state, resulting in lateral force during loading. The lateral force will cause the force transmission to no longer be along the axial direction, but deviate from the axis, resulting in the generation of non-axial force. The lateral force will not only cause uneven force transmission and affect the accuracy of the force-displacement curve, but also aggravate the mechanical wear of the system, resulting in uncertainty and fluctuations in the detection results. Especially during reciprocating motion, this deviation will continue to accumulate, resulting in a significant reduction in detection accuracy.

[0112] Problems with the constraints on degrees of freedom of moving parts: During the reciprocating motion of the power indicator transmission assembly 802, its motion direction along the displacement axis needs to be strictly limited to avoid generating redundant degrees of freedom in other directions. If the degrees of freedom of the power indicator transmission assembly 802 are not effectively constrained, such as lateral displacement or rotational motion, this will directly affect the force transmission efficiency and cause force deviation. If the degree of freedom control is not precise, the power indicator transmission assembly 802 may have a slight offset during the motion, causing the pull rod assembly to deviate from the displacement axis M, affecting the stability of the entire system. This offset will not only lead to unstable force transmission during the detection process, but also cause equipment vibration or irregular motion, reducing the life and performance of the system.

[0113] The problem of maintaining accuracy in high-frequency reciprocating motion: In the detection scenario of high-frequency reciprocating motion, the mechanical structure of the system needs to withstand frequent load and direction changes. Any misalignment or displacement deviation will gradually increase with the increase of the reciprocating motion frequency. Especially at high speeds, a slight instability in the force transmission path will lead to large errors. High-frequency reciprocating motion requires the system to have extremely high concentricity and structural rigidity. Any slight deviation will cause fluctuations in the measurement results. Without effective axis control means, force transmission will be unstable, and the detection data may fluctuate unpredictably, affecting the accuracy of the overall measurement.

[0114] Based on this, in order to effectively solve the above technical problems, the present invention designs a complete fixed axis unit system through the first fixed axis component 9 and the second fixed axis component 10, ensuring that the power indicator transmission component 802 and the pull rod component always maintain a coaxial state during the movement, and realizing the precise transmission of force and the stability of the system. Through the contact between the second fixed axis component 10 and the pull rod component, it is ensured that the axis of the pull rod component always remains coaxial with the displacement axis M. This design can effectively eliminate the lateral force caused by the axis offset, so that the force applied to the pull rod component is always transmitted axially, avoiding the interference of non-axial forces. By ensuring that the force transmission path is stable, the fixed axis unit can significantly improve the accuracy of detection, make the measured force-displacement curve smoother and more accurate, especially in high-precision damper detection, it can ensure that the results of each detection are consistent. The first fixed axis component 9 constrains the freedom of movement of the transmission component by sliding contact with the end of the power indicator transmission component, so that it can only reciprocate along the direction of the displacement axis M. The fixed axis component effectively avoids the movement or rotation of the transmission component in other directions, thereby ensuring that the overall motion trajectory of the system does not deviate. This degree of freedom restriction ensures that during the reciprocating motion, the force transmission always remains along the same axis, and there will be no force transmission deviation caused by lateral displacement or rotation, thereby improving the stability of the entire system and the reliability of the measurement data.

[0115] In addition, during high-speed reciprocating motion, the fixed axis unit can ensure that the power indicator transmission assembly 802 and the pull rod assembly always remain in a coaxial state, avoiding displacement deviations caused by frequent motion. The fixed axis assembly limits excess degrees of freedom of motion, allowing the system to maintain structural stability under high-speed loads and avoid vibration or force transmission fluctuations. Under high-frequency motion, the precise motion control of the fixed axis unit can greatly reduce measurement errors, allowing the system to provide high-precision detection results even under complex working conditions. Especially in dynamic detection that requires precision, the fixed axis unit effectively guarantees the overall performance of the system and the consistency of measurement data.

[0116] Therefore, through the application of the fixed axis unit, the entire damper assembly system has been significantly improved in terms of detection accuracy, equipment stability and service life, ensuring the efficiency and reliability of the dynamometer detection.

[0117] In one specific embodiment, the tooling assembly 202 has a fixed structure;

[0118] The fixing structure is disposed at the first station 2021 and the second station 2022 of the tooling assembly 202;

[0119] Wherein, the fixing structure includes a first axis positioning member 20241 and a second axis positioning member 20242;

[0120] Furthermore, the axis of the first axis positioning member 20241 located at the first station 2021, the axis of the second axis positioning member 20242 and the displacement axis M are coaxial;

[0121] Furthermore, the axis of the first axis positioning member 20241 located at the second workstation 2022, the axis of the second axis positioning member 20242 and the displacement axis M are coaxial.

[0122] In this embodiment, the first axis positioning member 20241 and the second axis positioning member 20242 are used to fix the damper on the tooling assembly 202 in the correct position. They respectively perform specific fixing functions to ensure that the damper maintains precise positioning during assembly and testing.

[0123] The first axis positioning member 20241 is a cylindrical structure, which is specially used to fix the lifting ring of the damper. The lifting ring is an important component in the damper structure, and a stable axis positioning needs to be maintained during the detection and assembly process.

[0124] The first axis locator 20241 is precisely embedded in the suspension ring of the damper through a cylindrical shape, ensuring that the suspension ring is coaxial with the displacement axis M of the entire system. Through this precise fixing method, the first axis locator 20241 not only provides mechanical support, but also ensures the centering of the suspension ring during testing and assembly.

[0125] The second axis positioning member 20242 is a magnetic arc-shaped platform for fixing the cylinder of the damper. The cylinder is the main part of the damper, which usually has a large surface area and weight, and therefore requires a firm support.

[0126] The curved table matches the shape of the damper barrel and is automatically positioned and fixed by magnetic attraction. The magnetic attraction technology ensures that the damper barrel does not slide or shift during operation, and that the barrel axis is consistent with the displacement axis M. The curved design increases the contact area and improves stability, so that the damper barrel can be firmly fixed in the predetermined position, avoiding axis deviation during assembly or testing.

[0127] The first axis positioning member 20241 fixes the lifting ring and the second axis positioning member 20242 fixes the cylinder body, and the two work together to achieve the overall fixation of the damper. During the entire assembly and testing process, the lifting ring and the cylinder body of the damper are stably fixed by the two positioning members, so that the axis of the damper always remains coaxial with the displacement axis M of the system.

[0128] The cylindrical first axis positioning member 20241 provides precise point positioning to ensure that the lifting ring does not rotate or deviate; the magnetic second axis positioning member 20242 further stabilizes the position of the barrel through the surface contact of the arc table. Together, the two ensure the precise centering and stability of the damper on the tooling assembly 202.

[0129] The first and second axis positioning members 20242 ensure that the suspension ring and the barrel of the damper always remain coaxial with the displacement axis M during the entire assembly and testing process through precise geometric design and magnetic fixing, thereby avoiding the problem of axis misalignment. This design eliminates the lateral force caused by position deviation, ensures that the force is transmitted along the axial direction, and improves the accuracy of the test results.

[0130] The application of magnetic technology not only enhances the fixing effect of the barrel, but also makes the operation easier. Without the need for additional mechanical locking devices, the magnetic structure can quickly fix and release the damper, improving the efficiency of assembly and testing.

[0131] The design of the curved platform can make good contact with the barrel of the damper, effectively dispersing the weight of the damper, avoiding local stress concentration, and preventing damage to the surface of the barrel. At the same time, the magnetic fixation will not cause wear on the surface of the damper, extending the service life of the equipment.

[0132] In this embodiment, the first axis positioning member 20241 (cylinder) and the second axis positioning member 20242 (magnetic arc platform) are respectively used to fix the suspension ring and the barrel of the damper. Through the precise design and coordination of these two positioning members, the axis centering and stability of the damper during assembly and testing are ensured.

[0133] In a specific embodiment, the second fixed axis assembly 10 includes:

[0134] A fixed-axis driving member 1001, wherein the fixed-axis driving member 1001 has a displacement away from or toward the damper;

[0135] Moreover, the displacement direction of the fixed-axis driving member 1001 is perpendicular to the direction of the displacement axis M;

[0136] A fixed axis block 1002 connected to the fixed axis driving member 1001;

[0137] The fixed axis block 1002 has an arc-shaped notch for contacting with the pull rod assembly.

[0138] The design of the second fixed axis assembly 10 is intended to ensure that the damper rod assembly remains coaxial with the displacement axis M during the dynamometer detection process, avoiding errors and system instability caused by axis misalignment. The specific structure includes a fixed axis drive 1001 and a fixed axis block 1002. The fixed axis drive 1001 is the core driving component of the second fixed axis assembly 10, which has the function of moving away from or toward the damper. The drive (such as a cylinder) controls the displacement of the fixed axis block 1002 in contact with the rod assembly, thereby achieving precise positioning of the rod assembly.

[0139] The displacement direction of the fixed axis driving member 1001 is perpendicular to the direction of the displacement axis M, that is, the fixed axis driving member 1001 moves in a direction perpendicular to the displacement axis M. Through this design, the fixed axis driving member 1001 can adjust the position of the fixed axis block in contact with the pull rod assembly to ensure that it always remains in a centered state with the damper. Since the fixed axis driving member 1001 can accurately adjust the position of the fixed axis block 1002 in the vertical direction, it can ensure that the fixed axis block 1002 is always in the best contact position by moving closer to or away from the damper during the assembly process or before the start of the test, so that the pull rod assembly is aligned with the displacement axis M to avoid deviation.

[0140] The fixed axis block 1002 is a component connected to the fixed axis driving member 1001, and has an arc-shaped notch, which is designed to contact the tie rod assembly. The curved surface design of the arc-shaped notch can fit tightly with the surface of the tie rod assembly, ensuring contact stability and uniform transmission of force. The fixed axis block 1002 contacts the outer contour of the tie rod assembly through its arc-shaped notch to provide positioning and support for the tie rod assembly. Since the tie rod assembly is usually circular or nearly circular in design, the arc-shaped notch can better contact its surface to avoid axis deviation caused by poor contact. The design of the arc-shaped notch can not only fit tightly with the tie rod assembly, but also disperse the force applied to the tie rod assembly to avoid deformation or damage of the assembly due to excessive local force. This design helps to ensure the stability and centering of the tie rod assembly during the entire dynamometer detection process.

[0141] In actual operation, the fixed axis driving member 1001 drives the fixed axis block 1002 to make fine adjustments in a direction perpendicular to the displacement axis M by its displacement away from or toward the damper, ensuring that the fixed axis block can accurately contact the tie rod assembly and maintain a coaxial state. The arc-shaped notch further ensures the stable positioning of the tie rod assembly, so that the tie rod assembly is always in the correct position during assembly or testing.

[0142] like Figures 9 to 11 As shown, in a specific embodiment, the first fixed axis component 9 includes:

[0143] The fixed axis disk 901 is connected to the power indicator transmission assembly 802;

[0144] Wherein, the circumferential wall surface of the fixed axis disk 901 is provided with a guide groove 902;

[0145] The guide groove 902 is an arc-shaped semi-open structure;

[0146] The fixed axis column 903 is slidably connected to the guide groove 902 .

[0147] In this embodiment, the design of the first fixed axis assembly 9 ensures that the movement of the power indicator transmission assembly is carried out within a limited range of freedom through the combination of the fixed axis disk 901, the guide groove 902 and the fixed axis column 903, thereby avoiding offset or error during the movement. The fixed axis disk 901 is a circular component fixed to the power indicator transmission assembly 802, and its main function is to provide a reference for the axis of the power indicator transmission assembly 802, while limiting its freedom of movement through the guide structure.

[0148] The fixed axis disk 901 is firmly connected to the power indicator transmission assembly 802 through a mechanical connection (such as a bolt or a buckle), ensuring that during the reciprocating motion, the fixed axis disk 901 and the power indicator transmission assembly 802 move synchronously. This connection ensures that the motion direction of the power indicator transmission assembly 802 is consistent with that of the fixed axis disk, thereby avoiding the axis deviation of the power indicator transmission assembly 802.

[0149] The guide groove 902 is provided on the circumferential wall surface of the fixed axis disk 901 and is designed as an arc-shaped semi-open structure. This design allows the fixed axis column 903 to slide in the guide groove 902 while limiting the range of motion of the fixed axis column 903 to ensure that it can only move along a predetermined trajectory.

[0150] Through the arc design, the guide groove 902 can guide the fixed axis column 903 to slide within a specific arc range, ensuring that its movement is consistent with the axis direction of the power indicator transmission assembly 802, avoiding the generation of redundant degrees of freedom. The semi-open design provides convenience for the fixed axis column 903 to enter the guide groove 902, and also provides certain constraints during the movement process to prevent the fixed axis column 903 from deviating in unnecessary directions.

[0151] The fixed axis column 903 is slidably connected to the guide groove 902. As a sliding component in the fixed axis assembly, the fixed axis column 903 can slide within a limited range in the arc structure of the guide groove to provide axial positioning of the transmission assembly. The sliding connection mode of the fixed axis column 903 allows it to slide freely in the arc guide groove 902, but at the same time it is constrained by the groove wall. This sliding connection effectively controls the deviation of the transmission assembly during movement and provides additional stability for the transmission assembly.

[0152] In a specific embodiment, it includes a lifting unit;

[0153] Wherein, the axis fixing unit and the detection unit are arranged on the lifting unit;

[0154] The lifting unit comprises:

[0155] A lifting frame 1101, connected to the frame 1;

[0156] A first lifting platform 1102 , slidably connected to the lifting frame 1101 ;

[0157] Furthermore, the detection unit and the first fixed axis assembly 9 are mounted on the first lifting platform 1102;

[0158] The second lifting platform 1103 is slidably connected to the lifting frame 1101 and is located below the first lifting platform 1102;

[0159] Furthermore, the second fixed axis assembly 10 is installed on the second lifting platform 1103;

[0160] The first lifting platform 1102 and the second lifting platform 1103 are lifted and driven respectively by independent driving systems.

[0161] Although in theory the force transmission will not be affected as long as the axis of the detection unit and the axis of the tie rod assembly are coaxial, in practice the height difference may indirectly affect the efficiency and path of force transmission, especially during dynamic loading:

[0162] When the detection unit and the damper are at different heights, if the detection unit is at an unbalanced or undesirable height position, the force transmission path may be unstable during loading, especially in the eccentric wheel structure. As the height difference increases, the force transmission path may become curved or uneven, which in turn affects the measurement results. By introducing the lifting unit, the detection unit can be accurately adjusted to a position that matches the damper height, reducing the deviation of the force transmission path during loading, ensuring that the force is transmitted in an ideal straight line direction, and improving the accuracy of the dynamometer test results.

[0163] In an eccentric structure, the application of loading force is nonlinear. The motion trajectory of the eccentric is constantly changing, and the direction of the applied force also changes accordingly. If there is a height difference, there may be a mismatch between the motion trajectory of the eccentric and the force application point of the damper:

[0164] At different loading angles, the force of the eccentric wheel may not be directly applied to the ideal position of the damper due to the height difference, resulting in an angle deviation in the force transmission path. This deviation is particularly obvious during high-frequency or high-amplitude loading, which may cause lateral force or other nonlinear force components, thereby affecting the accuracy of the test data. By adjusting the height of the detection unit through the lifting unit, so that it always maintains a suitable relative height with the damper at different eccentric wheel angles, it can effectively reduce the path error of force transmission during loading, ensure the linearity and uniformity of force transmission, and thus improve the accuracy of dynamometer detection.

[0165] Even if the axis can remain coaxial, if there is a significant height difference between the detection unit and the damper, the eccentric wheel may cause uneven force on the overall structure of the system when applying force, or even produce slight tilt or vibration. This slight mechanical asymmetry may produce non-axial force, which in turn affects the result of the dynamometer test. By introducing a lifting unit, the height of the detection unit can be dynamically adjusted to ensure that it is always at the ideal height position of the damper, avoiding structural asymmetry caused by height difference and the non-axial force interference it brings.

[0166] like Figures 6 to 8 As shown, the detection unit includes a first power display unit 501 and a second power display unit 502. The first power display unit 501 is responsible for detecting the mechanical properties of the damper in the first station 2021 and the upright state, and the second power display unit 502 performs corresponding detection on the damper in the inverted state in the second station 2022.

[0167] Specifically, the types of hydraulic shock absorbers are divided into:

[0168] Single-tube hydraulic shock absorber: Hydraulic oil and gas share a cylinder, and the movement of the piston flows between the oil chamber and the gas chamber to produce a damping effect. Its advantages are simple structure and low cost, but the problem of oil and gas mixing may occur during continuous use, thus affecting the damping effect.

[0169] Double-tube hydraulic shock absorber: hydraulic oil and gas are separated in two independent cylinders, and the damping effect is produced by the movement of the piston in the oil chamber. Its advantages are stable performance and good heat dissipation, but the structure is relatively complex and the manufacturing cost is relatively high.

[0170] For monotube hydraulic shock absorbers, the existing technology usually performs dynamometer testing in an upright state. However, since the damping force between the hydraulic oil and the tie rod assembly inside the monotube shock absorber is very small, it is difficult for the dynamometer to capture the force changes, resulting in inaccurate dynamometer results. In this case, it is difficult to accurately evaluate the performance of the shock absorber, which in turn affects product quality control and optimization and improvement.

[0171] Based on this, the detection unit includes a first power indicator unit 501 and a second power indicator unit 502. Each power indicator unit corresponds to a different station of the tooling assembly 202, and through reasonable station switching, it is ensured that the damper is fully and accurately detected in different states.

[0172] The first power indicator unit 501 is responsible for testing the mechanical properties of the damper in the first workstation 2021 in the upright state. However, in the upright state, since the spring of the damper rod assembly of the single-tube structure is mainly located in the upper half, and the hydraulic oil is usually concentrated at the bottom of the oil cylinder, the contact area between the spring and the hydraulic oil is small. At this time, the damping effect of the damper is weak, and it is difficult for traditional power indicator devices to accurately capture such tiny damping changes.

[0173] In order to solve the above problems, the second power indicator unit 502 is introduced in this embodiment, which is specifically used to detect the damper in the inverted state at the second workstation 2022. In the inverted state, the spring of the pull rod assembly is located at the bottom and is in full contact with the hydraulic oil at the bottom, which increases the damping effect between the spring and the hydraulic oil. This design enables the power indicator device to more easily capture the damping changes, thereby providing more accurate mechanical performance data.

[0174] In order to realize the above detection function, this embodiment also adds the following key components:

[0175] The first switching unit 401 and the second switching unit 402:

[0176] The first switching unit 401 is arranged at the front position of the detection unit, and is responsible for switching the damper of the monotube structure from the first station 2021 (upright state) to the second station 2022 (inverted state). The second switching unit 402 is arranged at the rear position of the detection unit, and is used to switch the damper from the second station 2022 (inverted state) back to the first station 2021 (upright state). This station switching mechanism ensures that the damper can be fully tested in different states.

[0177] The tooling assembly 202 includes a first station 2021 and a second station 2022, which correspond to the upright and inverted damper states, respectively. During the entire assembly and testing process, the tooling assembly 202 is driven by the conveying assembly 201 to move along a circular line to ensure smooth switching and precise positioning of the damper between various stations.

[0178] By providing the first and second power indicator units 502 and the corresponding switching units, this embodiment effectively overcomes the shortcomings of the prior art, especially the problem that the power indicator in the upright state is difficult to accurately capture the damping change. The detection in the inverted state further improves the accuracy of the damper performance evaluation, so that the entire assembly system can better control product quality.

[0179] This embodiment realizes accurate detection of the monotube structural damper in different states by adding the first power indicator unit 501 and the second power indicator unit 502 in the detection unit, and cooperating with the station switching operation of the first switching unit 401 and the second switching unit 402. This design not only improves the accuracy of the power indicator test, but also provides a reliable guarantee for the comprehensive performance evaluation of the damper, thereby effectively improving the detection efficiency and product quality control capability of the entire assembly system.

[0180] The present invention further improves the detection capability of the damper assembly system by optimizing the configuration of the power indicator unit. The bidirectional power indicator terminal design ensures that the system can flexibly and efficiently detect dampers in different structures and states, thereby providing a strong technical guarantee for the high-quality production of dampers.

[0181] In a specific embodiment, the power indicator drive assembly 801 can be in the form of a motor or a pneumatic device to ensure stable and accurate operation under various working conditions. The power indicator transmission assembly 802 is connected to the power indicator drive assembly 801, and its function is to transmit the power generated by the drive assembly to the power indicator detection clamp. The design of the power indicator transmission assembly 802 takes into account the force transmission efficiency and the smoothness of movement, and may include mechanical transmission elements such as gears, chains or slide rails. Alternatively, an eccentric wheel structure is used. Through this transmission structure, the power indicator detection clamp can move back and forth along a specified path above the work surface 101.

[0182] like Figures 1 to 5 As shown, the second embodiment of the present invention provides a damper assembly system, and based on the previous embodiment, the first switching unit 401 and the second switching unit 402 have the same structure;

[0183] Each switching unit includes:

[0184] A switching drive member 601 connected to the work surface 101;

[0185] A switching claw 602 connected to the switching driving member 601;

[0186] Wherein, the switching driving member 601 is configured to drive the switching claw 602 to move toward or away from the tooling assembly 202;

[0187] Furthermore, the switching driving member 601 is configured to drive the switching claw 602 to rotate.

[0188] In this embodiment, the structures of the first switching unit 401 and the second switching unit 402 are unified and simplified, so that the operation of the entire system is more efficient, stable, and easy to maintain.

[0189] The first switching unit 401 and the second switching unit 402 adopt the same structural design. This unified design simplifies the manufacturing and maintenance process of the system, while ensuring the consistency and reliability of the switching operation.

[0190] Each switching unit includes a switching drive 601 connected to the work surface 101. The drive is the core component of the switching operation and is responsible for providing power to drive the movement and rotation of the switching claw 602.

[0191] The switching drive 601 can be an electric or pneumatic device, which can provide stable power output under different operating conditions and ensure the accuracy of the switching operation.

[0192] The switching claw 602 is connected to the switching drive 601, and its function is to grab or release the damper and switch between workstations. The switching claw 602 is designed to be able to move toward or away from the tooling assembly to adapt to different operating requirements. The switching claw 602 also has a rotation function and can perform appropriate rotation operations according to the state of the tooling assembly, thereby achieving precise positioning and switching of the damper.

[0193] In actual operation, the switching drive 601 drives the switching claw 602 to move and rotate, so that the damper can be smoothly switched between the first station 2021 and the second station 2022. This switching operation is not only accurate and reliable, but also can adapt to the station requirements of different types of dampers.

[0194] By adopting the same structural design, the manufacturing and maintenance of the system are simplified, while the consistency and stability of the switching operation are improved.

[0195] The precise cooperation between the switching drive member 601 and the switching claw 602 ensures the high-precision execution of each switching operation, effectively reduces the operation error, and improves the efficiency of assembly and detection.

[0196] The rotation and displacement functions of the switching claw 602 enable the system to flexibly adapt to the states of different tooling components and meet complex assembly and detection requirements.

[0197] like Figure 4 As shown, the third embodiment of the present invention provides a damper assembly system, and based on the previous embodiment, the tooling assembly 202 includes:

[0198] A movable seat 2023 connected to the conveying assembly 201;

[0199] A fixed seat 2024 connected to the movable seat 2023;

[0200] Wherein, the fixing structure is arranged on the fixing seat 2024 .

[0201] In this embodiment, the fixing structure of the tooling assembly 202 is improved to improve the stability and positioning accuracy of the workpiece at different workstations, thereby improving the overall assembly efficiency and quality. The moving seat 2023 is the basic part of the tooling assembly 202 and is connected to the conveying assembly 201. The function of the moving seat 2023 is to move the fixed seat 2024 and the damper workpiece between different workstations along the conveying line to ensure the continuity and efficiency of the assembly and inspection process. The fixed seat 2024 is connected to the moving seat 2023 and is a component that directly carries and fixes the damper workpiece.

[0202] like Figures 1 to 5 As shown, the fourth embodiment of the present invention provides a damper assembly system, and based on the previous embodiment, the assembly unit includes:

[0203] A first assembly device 701 is disposed on the work surface 101;

[0204] Wherein, the first assembly device 701 is configured to pick up the oil seal to the tooling assembly 202;

[0205] The second assembly device 702 is arranged at a rear position of the first assembly device 701;

[0206] Wherein, the second assembly device 702 is configured to pick up the sealing gasket to the tooling assembly 202;

[0207] A third assembly device 703, arranged at a rear position of the second assembly device 702;

[0208] Wherein, the third assembly device 703 is configured to pick up the dust cover to the tooling assembly 202;

[0209] The fourth assembly device 704 is arranged at a rear position of the third assembly device 703;

[0210] Wherein, the fourth assembly device 704 is configured to pick up nuts to the tooling assembly 202;

[0211] Furthermore, each assembly device includes a storage component 302 and a clamping component 301 .

[0212] In this embodiment, the assembly unit design in the damper assembly system is further expanded and optimized. Based on the previous embodiment, this embodiment designs multiple assembly devices in detail to achieve automated and precise assembly of various damper accessories, further improving assembly efficiency and product quality.

[0213] The first assembly device 701 is disposed on the work surface 101, and is used to pick up the oil seal and install it on the damper in the tooling assembly 202. The oil seal is an important component of the damper, and the accuracy of its installation directly affects the sealing performance and service life of the damper.

[0214] The second assembly device 702 is arranged at the rear position of the first assembly device 701, and is specifically responsible for picking up the sealing gasket and installing it on the damper in the tooling assembly 202. The function of the sealing gasket is to further enhance the sealing effect and ensure the reliability of the damper under high pressure.

[0215] The third assembly device 703 is arranged at the rear position of the second assembly device 702, and is used to pick up the dust cover and install it on the damper. The dust cover can effectively prevent external dust and impurities from entering the damper, thereby extending its service life.

[0216] The fourth assembly device 704 is arranged at a rear position of the third assembly device 703, and is responsible for picking up the nut and fixing it on the damper. The installation of the nut is very important for the overall structural strength and stability of the damper.

[0217] Each assembly device includes a storage component 302 and a clamping component 301. The storage component 302 is used to store various accessories to ensure that the required parts can be continuously supplied during the assembly process. The clamping component 301 is used to accurately grasp and install various accessories to ensure the accuracy and efficiency of the assembly operation.

[0218] This design can realize a continuous and automatic assembly process, reduce human intervention, reduce error rates and improve production efficiency.

[0219] In a specific embodiment, the storage component 302 is a vibrating conveyor tray, and the clamping component 301 is a mechanical claw. The vibrating conveyor tray is used to store various accessories, and the clamping component 301 is used to pick up the corresponding accessories and send them to the tooling component 202.

[0220] A fifth embodiment of the present invention provides a damper assembly system, and based on the previous embodiment, comprises:

[0221] A groove rolling unit 705 is provided between the first assembly device 701 and the second assembly device 702;

[0222] Wherein, the groove rolling unit 705 has a groove rolling driving member and a groove rolling member;

[0223] The groove rolling driving member is configured to drive the groove rolling member to roll grooves on the circumferential wall surface of the oil cylinder.

[0224] In this embodiment, the damper assembly system is further improved by introducing a groove rolling unit 705 to enhance the processing capability of the oil cylinder. Based on the aforementioned assembly unit, this embodiment adds a groove rolling operation to ensure that the circumferential wall of the oil cylinder can be properly processed, thereby improving the sealing and mechanical properties of the damper. The groove rolling unit 705 is arranged between the first assembly device 701 and the second assembly device 702. This position is selected to roll the circumferential wall of the oil cylinder before the oil seal is installed, to ensure that the oil seal and sealing gasket assembled later can fit tightly with the oil cylinder, and improve the overall sealing performance. The groove rolling drive is the core component of the groove rolling unit 705, which is responsible for providing power to drive the groove rolling component to operate. The groove rolling drive can be an electric or pneumatic device, which can maintain stable power output under different working conditions. The groove rolling component is connected to the groove rolling drive and is responsible for directly rolling the circumferential wall of the oil cylinder. The design of the grooved parts takes into account the material and thickness of the oil cylinder, and can form uniform grooves without damaging the oil cylinder structure, ensuring that the oil seal and other components can be installed securely.

[0225] In actual operation, after the oil cylinder is initially processed by the first assembly device 701, it enters the groove rolling unit 705. In the groove rolling unit 705, the groove rolling driving member drives the groove rolling member to perform a groove rolling operation on the circumferential wall surface of the oil cylinder, and then the oil cylinder is transferred to the second assembly device 702 for the next step of operation.

[0226] Grooving can significantly enhance the bonding strength between the oil seal and sealing gasket and the oil cylinder, reduce the potential risk of leakage, and thus improve the overall sealing performance of the damper. Grooving not only helps the sealing performance, but also increases the surface strength of the oil cylinder, improving its durability and fatigue resistance.

[0227] In a specific embodiment, the specific structure of the groove rolling unit 705 is as follows:

[0228] Roller groove drive:

[0229] Motor: The core of the groove drive is a high-precision motor that is responsible for providing stable power for the groove operation. The motor can adjust the speed and torque according to the requirements of different barrel materials and wall thickness to ensure precise control during the groove process.

[0230] Control system: The matching control system allows the operator to set the depth, speed and pressure of the groove through the programming interface. This flexibility can adapt to the processing requirements of different types of oil cylinders and ensure the consistency of the groove quality.

[0231] Roll groove parts:

[0232] Roller: The grooved parts are mainly composed of multiple rollers, which are evenly distributed along the circumference of the oil barrel. The outer surface of each roller is hardened to ensure that there is no wear during the processing, while providing a stable indentation effect.

[0233] Roller stand: The rollers are fixed on an adjustable roller stand, which can adjust the distance between the rollers according to the diameter of the oil drum to ensure uniformity and consistency of the grooving operation.

[0234] Guide system: The groove rolling unit 705 is equipped with a precision guide system to ensure that the oil cylinder maintains stable linear motion during the groove rolling process. The guide system is made of high-strength material with high wear resistance and low friction coefficient, and can provide smooth guidance under high loads.

[0235] The sixth embodiment of the present invention provides a damper assembly system, and based on the previous embodiment, comprises:

[0236] A sealing unit 706, disposed between the second assembly device 702 and the detection unit;

[0237] Wherein, the sealing unit 706 comprises a sealing drive member and a sealing member;

[0238] The sealing drive is configured to drive the sealing member to crimp the port of the oil cylinder.

[0239] In this embodiment, the function of the damper assembly system is further optimized by introducing a sealing unit 706 to perform a crimping process on the port of the oil cylinder. This design is intended to improve the sealing and structural strength of the damper and ensure reliability in high pressure and high stress environments. The design and integration of the sealing unit 706 make the entire assembly system more complete and efficient.

[0240] Drive device: The sealing drive is the core component of the sealing unit 706, which is responsible for providing power to drive the sealing part to perform the crimping operation. The sealing drive can be an electric, pneumatic or hydraulic drive device, and the specific choice depends on the needs of the production line and the material characteristics of the oil barrel.

[0241] Control system: The sealing drive is equipped with a sophisticated control system that allows the operator to set the pressure, speed and angle of the crimping to meet the sealing requirements of different specifications of oil cylinders. The control system can also monitor the parameters of the crimping process in real time to ensure that the sealing operation of each oil cylinder meets the quality standards.

[0242] Sealing parts: Sealing parts mainly include one or more crimping tools, which can accurately crimp the port of the oil barrel. The design of the crimping tool takes into account the hardness and thickness of the oil barrel material, and can form a uniform crimp without damaging the oil barrel, ensuring that the oil seal fits tightly with the oil barrel. For example, the rolling wheel is usually made of high-strength alloy steel and the surface is quenched to improve hardness and wear resistance. The surface of the rolling wheel can also be chrome-plated or other anti-corrosion treatments to extend its service life. The shape of the rolling wheel is designed to conform to the specific geometry of the oil barrel port, so that it can gradually curl the oil barrel port into the desired shape during the rolling process. Usually, the profile of the rolling wheel will have a certain curvature to match the edge of the oil barrel.

[0243] Adjustable bracket: The crimping tool is mounted on an adjustable bracket, which can be adjusted according to the size of the oil cartridge to ensure that the crimping tool can be accurately aligned with the oil cartridge port.

[0244] The crimping operation creates a closer contact between the oil seal and the oil barrel, which significantly improves the sealing performance of the damper and prevents fluid leakage. The crimping process also enhances the mechanical strength of the oil barrel port, making it more resistant to high pressure or high stress conditions, extending the service life of the damper.

[0245] In one embodiment, the crimping tool is equipped with a pressure regulating device for regulating the pressure applied by the rolling wheel to the oil barrel port. The pressure regulator can ensure the stability of the pressure during the crimping process by mechanical or electronic control to avoid crimping defects caused by excessive or insufficient pressure.

[0246] The seventh embodiment of the present invention provides a damper assembly system, and based on the previous embodiment, comprises:

[0247] A loading unit 707, arranged in front of the first assembly device 701;

[0248] A material unloading unit 708, which is arranged at a rear position of the fourth assembly device 704;

[0249] Wherein, the loading unit 707 is configured to pick up the oil cylinder to the tooling assembly 202;

[0250] The unloading unit 708 is configured to pick up the molded damper and leave the damper assembly system.

[0251] In this embodiment, the damper assembly system is further improved, and a fully automated workpiece processing process is realized by introducing a loading unit 707 and a unloading unit 708. This design makes the loading and unloading operations of the oil cylinder and the molded damper more efficient and accurate, further improving the automation level and overall production efficiency of the production line.

[0252] The loading unit 707 is disposed at the front position of the first assembly device 701 and is mainly responsible for automatically picking up the oil cylinder from the storage position or the conveyor belt and accurately placing it on the tooling assembly 202 for subsequent assembly operations.

[0253] Robotic Arm: Loading Unit 707 is equipped with a robotic arm with a specially designed gripper at the end for grabbing oil drums of different sizes and shapes. The robotic arm has multi-degree-of-freedom motion capabilities and can accurately pick up oil drums from storage locations and place them in designated locations.

[0254] Vacuum suction cup or magnetic device: Depending on the material and surface characteristics of the oil cylinder, the gripping fixture may use a vacuum suction cup or a magnetic device to ensure that the oil cylinder is not damaged during the gripping process and maintain a firm control.

[0255] Sensor system: The loading unit 707 is equipped with a variety of sensors, including photoelectric sensors and laser rangefinders, to accurately detect the position and orientation of the oil drum to ensure the accuracy of the grabbing process.

[0256] Positioning system: Through the precise positioning system, the robot arm can adjust its motion path according to real-time feedback to ensure that the oil cylinder can be accurately placed on the tooling assembly 202.

[0257] The unloading unit 708 is disposed at a rear position of the fourth assembly device 704 and is responsible for automatically picking up the formed damper from the tooling assembly 202 and transferring it to a designated storage area or the next process after the damper is assembled.

[0258] Pick-up mechanism:

[0259] Robotic arm: Similar to the loading unit 707, the unloading unit 708 is also equipped with a robotic arm, but its grabbing fixture design takes into account the structure and weight of the molded damper, ensuring that the picking and transfer operations are completed safely without damaging the damper.

[0260] Discharging system:

[0261] Conveyor or Storage Rack: The unloading unit 708 is typically connected to a conveyor or storage rack, where the robotic arm places the formed dampers for further processing or storage.
