Description

Technical Field

[0001] The invention belongs to the technical field of shock absorber assembly, relates to a technology for improving shock absorber assembly accuracy, and specifically relates to shock absorber assembly equipment. Background Art

[0002] Shock absorbers are key components used in various devices such as vehicles and mechanical equipment to absorb vibrations and reduce impacts. In order to ensure that the shock absorber can maintain a stable working state under complex working conditions, its assembly accuracy is usually required to be extremely high, usually requiring a tolerance range of a few tenths of a millimeter, that is, an accuracy of more than ten microns (1 wire = 0.01 mm). Any error in the assembly process may cause the performance of the shock absorber to deteriorate or malfunction. Therefore, in the shock absorber production line, accurate assembly and positioning are one of the key steps to ensure product quality.

[0003] In modern assembly technology, position sensors are widely used in workstation positioning and motion control. Position sensors detect the position of assembly parts and transmit their real-time data to the control system to achieve precise positioning. However, in the prior art, when position sensors are used for workstation positioning, there are:

[0004] Position sensors rely on real-time signal transmission. After the sensor transmits the detected position data to the control system, the control system needs to calculate and send instructions to adjust the position of the equipment. However, on high-speed automated production lines, delays in signal transmission and processing can cause slight misalignments between assembly stations and assembly parts. This slight error is particularly prominent in shock absorber assembly, because the assembly accuracy requirements of shock absorbers are very high, and any slight deviation will affect their final performance.

[0005] Conveyors are devices used to move and position workpieces in automated production lines. Due to the inertial effect of conveyors, especially during rapid movement, assembly parts may overshoot or stop late when they reach the intended position. Even with precise control systems, motion inertia can still cause slight displacement of the workpiece when it stops, further exacerbating assembly accuracy issues. Summary of the invention

DETAILED DESCRIPTION

[0062] 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.

[0063] See also Figures 1 to 8 As shown, the specific embodiments provided by the present invention are as follows:

[0064] like Figure 1 to Figure 2 As shown, the first embodiment of the present invention provides a shock absorber assembly device, comprising:

[0065] Assembly platform 1;

[0066] A conveying structure 2, disposed on the assembly platform 1, configured to be driven along a circular route;

[0067] A plurality of loading platforms 3, connected to the conveying structure 2, for providing loading stations for various accessories of the shock absorber;

[0068] A plurality of assembly structures 4 are arranged on one side of the conveying structure 2, each assembly structure 4 corresponds to a work station, and is used to load various accessories of the shock absorber onto the bearing platform 3;

[0069] A positioning structure, disposed on the assembly structure 4, configured to detect whether the carrier platform 3 has reached a corresponding station in a non-contact manner;

[0070] A correction component 6 is disposed at a workstation corresponding to each assembly structure 4 and is configured to position the carrier platform 3 to a set position in a contact manner after the positioning structure detects that the carrier platform 3 has reached the corresponding workstation;

[0071] Wherein, the carrying platform 3 has a degree of freedom A and a degree of freedom B relative to the conveying structure 2;

[0072] The degree of freedom A is configured such that in response to the positioning of the correction assembly 6 , the carrier 3 performs a first linear displacement along the conveying direction;

[0073] The degree of freedom B is configured such that in response to the positioning of the correction assembly 6 , the carrier 3 performs a second linear displacement perpendicular to the conveying direction;

[0074] Furthermore, the set position means that the accessory on the carrying platform 3 is coaxial with the accessory currently loaded on the assembly structure 4 .

[0075] In this embodiment, the shock absorber assembly equipment can effectively improve the assembly accuracy and reduce the positioning error caused by inertia and signal delay during the shock absorber assembly process by optimizing the design of the conveying structure 2 and the correction component 6.

[0076] Specifically, the assembly platform 1 is the basic supporting component of the equipment, carrying all other functional units. The conveying structure 2 is set on the assembly platform 1 and driven along a circular route. The carrying platform 3 moves continuously on the production line through the conveying structure 2. Through this circular route, multiple assembly stations can work synchronously, ensuring the efficiency of the assembly process.

[0077] The carrier 3 is connected to the conveying structure 2 and serves as a loading station for the shock absorber accessories. Each carrier 3 can accommodate one or more shock absorber accessories. On this basis, the carrier 3 has two degrees of freedom - degree of freedom A and degree of freedom B, so that it can be fine-tuned relative to the conveying structure 2 when adjustment is required. This design allows the carrier 3 to be linearly displaced in the conveying direction (degree of freedom A) and perpendicular to the conveying direction (degree of freedom B) to cope with possible positioning deviations during the assembly process. Among them, the directions of the first linear displacement and the second linear displacement are in the same plane.

[0078] More specifically, the conveying structure 2 adopts a chain conveying form, and the supporting platform 3 is installed on the chain. The chain itself has a certain flexibility and can provide a small displacement adjustment capability in two mutually perpendicular directions (the conveying direction and perpendicular to the conveying direction), thereby forming degrees of freedom A and degrees of freedom B.

[0079] The flexibility of the chain and the elastic structure of the connection point allow the carrier 3 to perform a small range of linear displacement along the conveying direction (i.e., the chain movement direction) during the chain conveying process. This feature ensures that the carrier 3 can be accurately positioned by fine-tuning the correction component 6 when it reaches the assembly station. This natural flexibility of the chain can absorb the impact caused by the inertia of movement within a small range, thereby correcting the positioning deviation.

[0080] At the same time, the structural design of the chain allows it to have a certain degree of flexibility in the direction perpendicular to the conveying direction. Through this flexibility, the carrier 3 can be slightly adjusted in the vertical direction to meet the requirements of the assembly in this direction. This adjustment is also controlled by the correction component 6 to ensure that the assembly and the accessories on the carrier 3 can be coaxially aligned during the assembly process.

[0081] The chain conveyor not only provides a degree of freedom A through its flexibility along the conveying direction, but also gives the carrier 3 a degree of freedom B by virtue of its lateral flexibility. Under this dual flexibility adjustment, the carrier 3 can be fine-tuned in two dimensions, so that the position error during the assembly process is minimized.

[0082] When the positioning structure (not shown in the figure) detects that the carrier 3 has arrived at the corresponding assembly station, it feeds back the position data of the carrier 3 to the control system through a non-contact sensor (such as a photoelectric sensor or a laser sensor). The positioning structure can quickly and accurately detect the position of the carrier 3, thereby providing a basis for subsequent precise adjustment. After detecting the position, the control system further calibrates the position of the carrier 3 through the correction component 6.

[0083] The positioning structure may be arranged at a workstation corresponding to each assembly structure 4 , or the positioning structure may be arranged at workstations corresponding to two or three of the assembly structures 4 .

[0084] The correction component 6 performs positioning adjustment by contact mode, and is responsible for fine-tuning the position of the carrier 3, so that the positions of the carrier 3 and the assembly parts in two directions can reach the required high precision. The function of the correction component 6 is to eliminate the deviation caused by the inertia of the conveying structure 2 or the signal delay, and ensure that the assembly parts and the parts on the carrier 3 can be accurately docked during the assembly process.

[0085] More specifically, the contact method for positioning adjustment has outstanding advantages, especially in high-precision assembly processes:

[0086] Contact positioning can achieve more precise displacement control by directly contacting the support platform 3 through a mechanical device. Compared with non-contact positioning methods (such as adjusting only by sensor data), the contact method can effectively eliminate positioning errors caused by signal delay or noise.

[0087] Since contact positioning is based on physical contact, its positioning accuracy can usually reach a very high level, which is especially suitable for occasions such as shock absorber assembly where the accuracy requirements reach a few tenths of a millimeter or even more than ten microns.

[0088] In automated assembly lines, the inertia effect of the conveyor often causes small displacement errors. The contact positioning device can be used to forcibly position the workpiece when it arrives at the assembly station, eliminating the position deviation caused by the inertia of the conveyor. This forced contact can quickly stabilize the carrier 3 when it reaches the set position, avoiding overshoot or position drift.

[0089] Because contact positioning involves direct physical contact, assembly equipment can obtain real-time physical feedback. This physical feedback can effectively shorten the system's reaction time, allowing the control system to make adjustments more quickly, thereby improving the responsiveness of the entire assembly line.

[0090] Contact positioning adjusts the position through the contact of the mechanical structure, which has better stability and repeatability than non-contact methods. Since the positioning accuracy and operation trajectory of the mechanical structure can be kept constant after calibration, the accuracy of each assembly can be stably guaranteed during the continuous assembly process.

[0091] For products such as shock absorbers that require extremely high assembly precision for each part, contact positioning can ensure repetitive accuracy during each assembly process, thereby improving the consistency of the overall assembly quality.

[0092] Moreover, a single action of the correction component 6 can simultaneously correct the position of the support platform 3 in two directions, which can further improve assembly efficiency and assembly accuracy, and is particularly suitable for assembly scenarios such as shock absorber assembly that require high precision and high speed.

[0093] Specifically, the conventional correction component 6 usually needs to be adjusted independently in two directions (such as degree of freedom A and degree of freedom B), which increases assembly time and control complexity. However, the correction component 6 in this embodiment adjusts the position of the carrier 3 in two directions at the same time through one action, which not only simplifies the complexity of the control system, but also significantly shortens the assembly time.

[0094] In addition, if the adjustment is performed in two directions in steps, the errors may gradually accumulate, especially in high-precision assembly scenarios, where small error accumulation may eventually affect the assembly quality. Through a single synchronous adjustment, the correction component 6 can perform precise corrections in two directions at the same time, reducing the error accumulation caused by multiple actions, thereby ensuring the overall accuracy of the assembly.

[0095] The set position in this embodiment is defined as the coaxial position of the assembly part and the assembled part on the carrier 3. Through the precise adjustment of the correction component 6, it is ensured that each component of the shock absorber can be correctly installed at the set position and meet the strict assembly tolerance requirements. Through this design, the shock absorber assembly equipment can achieve high automation and meet the requirements of high-precision assembly.

[0096] Through the technical solution in this embodiment, the assembly equipment can effectively solve the problem of inaccurate positioning caused by signal transmission delay and motion inertia in the prior art. The dual-degree-of-freedom design of the support platform 3 and the fine-tuning function of the correction component 6 enable the shock absorber assembly accuracy to reach the level of a few tenths of a millimeter, greatly improving the overall performance of the assembly line and product quality. This highly automated assembly method can meet the manufacturing needs of shock absorbers with extremely high precision requirements, and avoid performance problems or product defects caused by assembly errors.

[0097] like Figures 3 to 8 As shown, the second embodiment of the present invention provides a shock absorber assembly device, and based on the first embodiment, the correction component 6 includes:

[0098] A driving member 601 is arranged on the assembly platform 1;

[0099] A rotating member 602 is rotatably connected to the driving member 601 and driven to rotate by the driving member 601;

[0100] A first correction member 603 connected to the rotating member 602;

[0101] A second correction member 604 connected to the carrier platform 3;

[0102] Furthermore, when the first correcting member 603 and the second correcting member 604 are in a coupled state, the first correcting member 603 drives the second correcting member 604 to perform a first linear displacement and a second linear displacement.

[0103] In this embodiment, the swinging action of the first correcting member 603 can push the second correcting member 604 to simultaneously perform linear displacement in two mutually perpendicular planar directions, namely the first linear displacement and the second linear displacement, thereby achieving precise position adjustment of the support platform 3 within the plane.

[0104] Specifically, the driving member 601 is arranged on the assembly platform 1, and is responsible for providing power to the correction component 6. The driving member 601 can be a cylinder. The driving member 601 transmits power to the rotating member 602 through a transmission mechanism to control the overall movement of the correction component 6. The rotating member 602 is connected to the driving member 601, and is used to convert the linear motion of the driving member 601 into a rotational motion, and further form the swinging motion of the first correction member 603. The rotating member 602 can be a rotating rod. The first correction member 603 swings through the action of the driving member 601 and the rotating member 602, and the end of the swing is coupled with the second correction member 604. As the first correction member 603 swings, it can simultaneously generate thrust in two mutually perpendicular planar directions, pushing the second correction member 604 to achieve bidirectional linear displacement.

[0105] That is, the first linear displacement (degree of freedom A): along the conveying direction, the position of the carrier 3 on the conveying path is adjusted.

[0106] Second linear displacement (degree of freedom B): In the horizontal direction perpendicular to the conveying direction, the lateral position of the carrier 3 is adjusted to ensure that the assembly and the parts on the carrier 3 can be accurately aligned.

[0107] When the carrier 3 reaches the assembly station, the positioning structure detects the current position and feeds back the information to the control system. The control system starts the driving member 601 as needed, and the driving member 601 drives the first correction member 603 to start swinging through the rotating member 602.

[0108] This embodiment successfully achieves synchronous linear displacement adjustment of the carrier 3 in two directions in the same plane through the swinging action of the first correction member 603. The swinging action makes the entire adjustment process more efficient, and simplifies the mechanical design while ensuring high precision, and is suitable for assembly occasions requiring high-precision plane alignment, such as shock absorber assembly lines.

[0109] like Figure 6 As shown, the third embodiment of the present invention provides a shock absorber assembly device, and based on the previous embodiment, the first correction member 603 forms a coupling head 6031, and the second correction member 604 forms a coupling groove 6041;

[0110] Furthermore, the coupling head 6031 and the coupling slot 6041 can be coupled;

[0111] Wherein, in the vertical direction, the first correction member 603 forms a flange 6032;

[0112] In the coupled state, the flange 6032 abuts against the lower surface of the coupling groove 6041 to correct the height of the second correcting member 604 .

[0113] In this embodiment, the first correction member 603 forms a coupling head 6031, and the second correction member 604 forms a coupling groove 6041. During operation, the two realize bidirectional linear displacement of the carrier 3 through the cooperation of the coupling head 6031 and the coupling groove 6041. In addition, the first correction member 603 forms a flange 6032 in the vertical direction, which abuts against the lower surface of the coupling groove 6041 of the second correction member 604 to realize position correction in the height direction.

[0114] Specifically, a coupling head 6031 is formed at the end of the first correction member 603, and the coupling head 6031 can be matched with a coupling slot 6041 on the second correction member 604. The design of the coupling head 6031 and the coupling slot 6041 ensures that when the first correction member 603 swings, the motion force can be effectively transmitted, thereby pushing the second correction member 604 to perform linear displacement in two directions.

[0115] The coupling head 6031 is a circular columnar structure, and the coupling groove 6041 is an arc-shaped groove structure adapted thereto.

[0116] The first correction member 603 is provided with a flange 6032 in the vertical direction (its diameter is larger than the diameter of the coupling head 6031). When the coupling head 6031 is inserted into the coupling groove 6041 of the second correction member 604, the flange 6032 abuts against the lower surface of the coupling groove 6041. This abutment structure enables the fine adjustment capability of the carrier 3 in the vertical direction (height direction).

[0117] The design of flange 6032 can effectively eliminate errors in the height direction, correct the height of the carrier platform 3 through physical contact, and ensure that the parts on the carrier platform 3 are completely aligned with the parts in the assembly station in the vertical direction.

[0118] In one embodiment, the regulating structure includes:

[0119] The correction component 6 is installed to the assembly platform 1 through the adjustment structure;

[0120] The adjustment structure is configured to adjust the position of the correction component 6 in the direction of the first linear displacement, so as to more accurately control the installation and adjustment of the correction component 6. The introduction of the adjustment structure enables the correction component 6 to flexibly adjust its position on the assembly platform 1, especially to adjust the position in the first linear displacement direction, thereby ensuring that the correction component 6 can more accurately control the position of the carrier 3 when performing fine adjustment.

[0121] The adjustment structure is a connection and adjustment device between the correction component 6 and the assembly platform 1. Its main function is to enable the correction component 6 to adjust its position in the first linear displacement direction (i.e., along the conveying direction) as required. Through this adjustment function, the working position of the correction component 6 can be optimized to meet different assembly requirements and ensure accurate assembly alignment.

[0122] The first linear displacement direction refers to the linear adjustment along the conveying direction, and the correction component 6 can be fine-tuned in this direction through the adjustment structure. This adjustment allows the correction component 6 to be adjusted to the best position before the specific assembly operation, so as to better perform the fine-tuning task of the carrier 3.

[0123] In a specific embodiment, the regulating structure comprises:

[0124] Adjustment slot 701 and adjustment seat 702;

[0125] Wherein, the adjustment groove 701 is opened on the assembly platform 1 along the direction of the first linear displacement;

[0126] The adjustment seat 702 is detachably connected to the adjustment slot 701 .

[0127] The specific design is a combination of an adjustment slot 701 and an adjustment seat 702, which can flexibly adjust the position of the correction component 6 in the first linear displacement direction. By setting the adjustment slot 701 on the assembly platform 1, the adjustment seat 702 can move along the direction of the adjustment slot 701, and the flexible adjustment and firm fixation of the correction component 6 are ensured by the detachable connection, thereby improving the adaptability and accuracy of the assembly equipment.

[0128] The adjustment slot 701 is a long slot opened on the assembly platform 1, and its direction is consistent with the first linear displacement direction, ensuring that the correction component 6 can be adjusted in parallel along the conveying direction. The design of the adjustment slot 701 allows the adjustment seat 702 to slide freely within its range, providing flexible adjustment capabilities.

[0129] The length and position of the adjustment slot 701 are optimized according to the design of the assembly platform 1 to ensure that the correction component 6 can be fine-tuned within a specified range to meet the precise positioning requirements of different workstations.

[0130] The adjustment seat 702 is connected to the correction component 6 and is detachably connected to the adjustment slot 701. The adjustment seat 702 can slide smoothly in the adjustment slot 701, so as to facilitate the adjustment of the position of the correction component 6. Through the detachable connection of the adjustment seat 702, the correction component 6 can be flexibly installed and disassembled according to assembly requirements.

[0131] like Figures 3 to 6 As shown, the fourth embodiment of the present invention provides a shock absorber assembly device, and based on the previous embodiment, the conveying structure 2 includes:

[0132] A driving component 201 and a restraining component 202;

[0133] The driving assembly 201 is arranged along a circular route, and the driving assembly 201 is connected to the carrying platform 3;

[0134] The constraint assembly 202 is disposed on the outer periphery of the driving assembly 201 and arranged along a circular route, and the bearing platform 3 is slidably connected with the constraint assembly 202;

[0135] Furthermore, the driving assembly 201 is in the form of a chain conveyor;

[0136] Furthermore, the restraining component 202 is in the form of a C-shaped groove.

[0137] In this embodiment, the stability and accuracy of the carrier 3 in the shock absorber assembly equipment during the conveying process are ensured by introducing a combined design of the driving component 201 and the restraining component 202. The chain conveying form of the driving component 201 and the C-shaped groove design of the restraining component 202 ensure that the carrier 3 can run smoothly in the circular conveying route and has good position adjustment capabilities.

[0138] Specifically, the driving assembly 201 is a power device for driving the carrier 3 to move along the circular route. The assembly adopts a chain conveying form, and drives the carrier 3 to run on the conveying track through the chain. The chain conveying form can provide continuous and smooth power transmission in a long conveying path, ensuring that the movement of the carrier 3 between different assembly stations is stable and reliable.

[0139] The constraint assembly 202 is located at the periphery of the driving assembly 201 and arranged along a circular route. Its function is to provide further guidance and constraint for the carrying platform 3, ensuring that the carrying platform 3 remains stable during the movement without deviation or shaking.

[0140] The restraint assembly 202 is in the form of a C-shaped groove, which is designed to be compatible with the sliding structure of the carrier 3. The bottom or side of the carrier 3 cooperates with the C-shaped groove through a sliding connection (such as a pulley), so that the carrier 3 can slide along the C-shaped groove in a controlled manner during the conveying process. This design allows the carrier 3 to maintain a high degree of stability when moving in the conveying direction, avoiding shaking or vibration caused by the inertia of the conveying system.

[0141] The fifth embodiment of the present invention provides a shock absorber assembly device, and based on the previous embodiment, the bearing platform 3 has:

[0142] A first fixed axis structure 801 and a second fixed axis structure 802;

[0143] Wherein, the first fixed axis structure 801 includes a slot body 1 8011 and a slot body 2 8012;

[0144] The first tank body 8011 and the second tank body 8012 are coaxial;

[0145] Wherein, the second fixed axis structure 802 includes a fixed axis rod 8021 and a fixed axis seat 8022;

[0146] The fixed axis rod 8021 and the fixed axis seat 8022 are coaxial.

[0147] In this embodiment, the first fixed axis structure 801 and the second fixed axis structure 802 are provided to respectively locate the tie rod assembly and the shock absorber assembly in coaxial position during assembly.

Through this design, it is ensured that the tie rod assembly accessories such as the tie rod, O-ring, tie rod piston, spring, etc. are strictly coaxial with other parts of the shock absorber during assembly.

[0150] The second fixed axis structure 802 is specifically used for axial positioning of the overall assembly of the shock absorber, including all shock absorber accessories including the tie rod assembly (such as oil reservoir, sealing gasket, spring seat, dust cover, shock absorber piston, nut, etc.), to ensure that they remain coaxial during the assembly process.

[0151] The structure is composed of a fixed axis rod 8021 and a fixed axis seat 8022, both of which are coaxially designed. The fixed axis rod 8021 provides a stable support for the shock absorber accessories, and the fixed axis seat 8022 provides precise positioning, so that the various shock absorber accessories can be stably arranged along the axis direction during the assembly process, avoiding dislocation or misalignment during the assembly process.

[0152] In a specific embodiment, the first fixed axis structure 801 is fixed to the pull rod assembly by magnetic attraction. The fixed axis seat 8022 of the second fixed axis structure 802 is fixed to the oil storage cylinder by magnetic attraction, and the fixed axis rod 8021 is inserted and connected with the pull rod of the oil storage cylinder.
