Description

Technical Field

[0001] This invention relates to the field of automotive parts installation, and more particularly to a front suspension installation production line. Background Technology

[0002] The front suspension assembly, also known as the front suspension system, is the core assembly that connects the front end of the car frame to the front axle and the cab. It integrates structures such as cantilever arms, support brackets, shock absorbers, and connecting fasteners. Its assembly precision directly determines the vehicle's driving stability, load-bearing safety, and handling performance, making it a key link in the manufacturing of the car chassis.

[0003] In the production and assembly process of truck front suspension components, three core processes need to be completed sequentially: component assembly, in-workshop transfer, and installation on the vehicle assembly line. In existing technologies, due to the large overall weight of the front suspension components, their high installation position, and the narrow bolt holes, traditional installation methods require 2-3 workers to work together. At least one person must lift and bear the weight throughout the process, while the others assist with alignment. This results in extremely high labor intensity, fatigue from prolonged work, low accuracy in bolt hole alignment, and poor assembly efficiency, severely restricting the production cycle of the vehicle assembly line.

[0004] Therefore, the aforementioned problems in the existing technology still need to be solved. Summary of the Invention

[0005] The main objective of this invention is to provide a front suspension installation production line that solves the problems of low assembly efficiency, high labor intensity, inconvenient transportation, and poor installation accuracy of front suspension components in the prior art through the coordinated operation of assembly tables, transfer lines, transfer vehicles, and installation fixtures arranged in sequence.

[0030] The front suspension assembly 10, also known as the front suspension component, is the core assembly connecting the front end of the vehicle frame 2100 to the front axle and cab. It integrates structures such as cantilever arms, support brackets, shock absorbers, and connecting fasteners. Its assembly precision directly determines the vehicle's driving stability, load-bearing safety, and handling performance, and is a key link in the manufacturing of the vehicle chassis.

[0031] In the production and assembly process of the front suspension component 10, three core processes need to be completed sequentially: component assembly, in-workshop transfer, and installation on the vehicle assembly line. In the existing technology, due to the large overall weight of the front suspension component 10, its high installation position, and the small bolt holes, the traditional installation method requires 2-3 operators to work together, with at least one person carrying the weight throughout the process while the others assist in alignment. This results in extremely high labor intensity, fatigue from prolonged work, low accuracy in hole alignment, poor assembly efficiency, and seriously restricts the production cycle of the vehicle assembly line.

[0032] Therefore, the aforementioned problems in the existing technology still need to be solved.

[0033] To address the aforementioned issues, this application provides a front suspension installation production line. Through the coordinated operation of the assembly table 100, transfer line 400, transfer vehicle 200, and installation fixture 300 arranged sequentially, the line solves the problems of low assembly efficiency, high labor intensity, inconvenient transfer, and poor installation accuracy of the front suspension component 10 in the prior art.

[0034] For ease of understanding, a detailed explanation is provided below.

[0035] like Figure 1 As shown in the embodiment of this application, a front suspension installation production line is disclosed for producing and assembling front suspension components 10 of a car 20. The line is characterized by comprising an assembly table 100, a transfer vehicle 200, and an installation fixture 300 arranged sequentially. The assembly table 100 supports the front suspension component 10 to be assembled. A transfer line 400 is provided between the assembly table 100 and the transfer vehicle 200, which transports the assembled front suspension component 10 from the assembly table 100 to the transfer vehicle 200. The transfer vehicle 200 receives the front suspension component 10 assembled on the assembly table 100 and transports it to the installation fixture 300. The installation fixture 300 is movably connected relative to a positioning point to clamp the front suspension component 10 transported by the transfer vehicle 200 and install the front suspension component 10 onto the car 20.

[0036] In this embodiment, the assembly table 100 serves as the core tooling for assembling the front suspension assembly 10. It suspends and stably locks the front suspension assembly 10 to be assembled, providing a stable working reference for processes such as component alignment, high-torque bolt tightening, and assembly gap adjustment. It effectively resists the torque generated during assembly, preventing workpiece displacement and loosening. The transfer line 400, as an intermediate link connecting the assembly table 100 and the transfer cart 200, enables convenient transfer of the front suspension assembly 10 between the two workstations, saving labor and significantly reducing labor intensity. The transfer cart 200 adopts a dedicated positioning structure, enabling multi-layer stacking and flexible transfer of the front suspension assembly 10. This improves workshop space utilization and avoids collision damage during transfer. The installation fixture 300 has multi-degree-of-freedom mobility and assistive functions, allowing a single person to complete the gripping, alignment, and installation of the front suspension assembly 10, completely solving the problem of traditional installation requiring multiple people. This application organically integrates the three processes of assembly, transfer, and installation to form an integrated front suspension installation production line, realizing efficient flow of the front suspension component 10 from assembly to installation, significantly improving production efficiency, reducing labor intensity, and ensuring assembly accuracy and production safety.

[0037] To further optimize the transfer efficiency of the front suspension assembly 10 between the assembly table 100 and the transfer vehicle 200, this application provides a preferred embodiment of the transfer line 400, as follows.

[0038] like Figure 1As shown, the transfer line 400 includes a transfer guide rail 410 and a transfer clamp 420. The transfer guide rail 410 is suspended from the ceiling or laid on the ground. The starting point of the transfer guide rail 410 is located at the assembly table 100, and the ending point of the transfer guide rail 410 is located at the starting point of the transfer vehicle 200. The transfer clamp 420 is slidably connected to the transfer guide rail 410. The transfer clamp 420 is used to clamp the front suspension component 10 that has been assembled on the assembly table 100 and move it along the transfer guide rail 410 to the transfer vehicle 200.

[0039] In this embodiment, the transfer guide rail 410 can be flexibly selected as either suspended or ground-laid according to the actual layout of the workshop, adapting to different production environments. The transfer fixture 420 reciprocates along the transfer guide rail 410, accurately transferring the assembled front suspension component 10 from the assembly table 100 to the designated position on the transfer vehicle 200. This transfer line 400 has a simple structure and stable operation, requiring no complex control system. During the transfer process, a single person can push it, or it can be automated. Only one operator needs to operate the transfer fixture 420 to complete the transfer operation of the front suspension component 10, significantly reducing the labor intensity of workers, while improving the flow efficiency between workstations and avoiding workpiece collision damage that may occur due to purely manual handling.

[0040] To enable flexible movement and precise alignment of the mounting clamp 300, and to facilitate the clamping and installation of the front suspension assembly 10, this application provides a preferred embodiment of the mounting clamp 300 with movable connection, as detailed below.

[0041] like Figure 1 As shown, the above-mentioned mounting clamp 300 is movably connected to the positioning point, including: the mounting clamp 300 is connected to the positioning column 320 through the assist mechanism 310, the positioning column 320 is fixed to the ground or suspended from the ceiling; the mounting clamp 300 can rotate freely relative to the positioning column 320 within a preset angle.

[0042] In this embodiment, the positioning post 320 is fixed to the ground or suspended from the ceiling, providing a stable origin for the installation clamp 300. The installation clamp 300 is connected to the positioning post 320 via a power-assist mechanism 310, allowing it to rotate freely relative to the positioning post 320 within a preset angle, thus covering the entire work area from the pick-up of the component from the transport vehicle 200 to the installation position on the vehicle 20. The power-assist mechanism 310 balances the weight of the front suspension assembly 10, requiring only a small force from the operator to guide the installation clamp 300 and the front suspension assembly 10 to the target position, eliminating the need for continuous lifting and bearing of the load. This structure allows a single worker to independently complete the entire process of picking up the front suspension assembly 10 from the transport vehicle 200, adjusting its posture, and precisely aligning and installing it with the vehicle frame 2100, completely solving the problem of traditional installation requiring multiple people, significantly reducing labor intensity, and improving installation efficiency and alignment accuracy.

[0043] It should be noted that there are no restrictions on the specific implementation of the installation fixture 300 rotating freely relative to the positioning post 320 within a preset angle. This application provides a preferred implementation as follows.

[0044] like Figure 2 As shown, the positioning column 320 includes a main column 321 and a sub-column 322. The main column 321 is fixed to the ground or suspended from the ceiling, and the sub-column 322 is located at the end of the main column 321. The sub-column 322 is rotatably connected to the main column 321. The mounting clamp 300 includes a mounting arm 330. The middle part of the mounting arm 330 is hinged to the sub-column 322, and the end of the mounting arm 330 is connected to the assist mechanism 310.

[0045] In this embodiment, the main column 321 serves as the positioning origin of the entire mounting fixture 300, providing a stable support foundation for the mounting arm 330. The sub-column 322 is rotatably connected to the main column 321, allowing the mounting arm 330 to rotate 360 ​​degrees horizontally around the axis of the main column 321, covering the entire horizontal working range. The middle part of the mounting arm 330 is hinged to the sub-column 322, allowing the mounting arm 330 to rotate vertically around the hinge axis, realizing the vertical height adjustment of the front suspension assembly 10. Through the combination of horizontal and vertical rotation, the mounting arm 330 can reach any position within the working range, flexibly adapting to the needs of different vehicle models and different installation positions. The end of the mounting arm 330 is connected to the assist mechanism 310, which provides assistance in the vertical rotation dimension of the mounting arm 330, balancing the weight of the front suspension assembly 10, allowing a single worker to easily lift the heavy front suspension assembly 10, significantly reducing the operational difficulty of high-position installation.

[0046] It should be noted that the specific implementation of the rotatable connection between the sub-post 322 and the main post 321 is not limited. This application provides a preferred embodiment as follows.

[0047] like Figure 2 As shown, a turntable 323 is provided on the main column 321, and a sub-column 322 is located at the center of the turntable 323; the assist mechanism 310 includes an assist cylinder, which is connected to the turntable 323, and the output shaft of the assist cylinder is hinged to the end of the mounting arm 330.

[0048] In this embodiment, the turntable 323 can rotate 360 ​​degrees relative to the main column 321. The sub-column 322 and the assist cylinder are both fixedly mounted on the turntable 323, so that the sub-column 322 and the assist cylinder can rotate synchronously with the turntable 323. This ensures that the relative position between the assist mechanism 310 and the mounting arm 330 remains unchanged during the horizontal rotation of the mounting arm 330, avoiding motion interference and ensuring the stability of the assist effect. The output shaft of the assist cylinder is hinged to the end of the mounting arm 330. The extension and retraction of the cylinder drives the mounting arm 330 to rotate up and down around the hinge axis, providing stable assistance to the mounting arm 330. It should be noted that the assist cylinder can be a hydraulic cylinder, a pneumatic cylinder, or a motor, or any other power component that can be used for assist, and is not limited to the forms listed in this embodiment.

[0049] The overall logic of the front suspension installation production line provided by the present invention has been explained above. The specific structures of the assembly table 100, the transfer line 400 and the installation fixture 300 are described in detail below.

[0050] like Figure 3 As shown in the embodiment of this application, the assembly table 100 is used to support the front suspension assembly 10. It includes a tooling table 110. The tooling table 110 has a plurality of support rods 1100 on its surface. The lower end of the support rod 1100 is fixedly connected to the table surface, and the upper end of the support rod 1100 is provided with a fixing clamp 1200. The fixing clamp 1200 includes a support block 1210 and a clamping block 1220. The support block 1210 is fixedly connected to the support rod 1100, and the clamping block 1220 is movably disposed above the support block 1210.

[0051] In this embodiment, multiple sets of support rods 1100 can be symmetrically distributed along the table surface of the tooling table 110. The front suspension component 10 to be assembled is suspended and supported above the table surface by the support rods 1100, providing sufficient operating space for the bottom bolt tightening, pipeline connection and other processes of the front suspension component 10, greatly reducing the assembly operation difficulty for operators and improving assembly efficiency. The support block 1210 and the clamping block 1220 cooperate to form a clamping structure. The support block 1210 is fixedly connected to the support rod 1100, which can provide stable pre-support for the front suspension component 10 placed on it, and avoid the problem of shaking or displacement of the front suspension component 10 after placement. The operator only needs to drive the clamping block 1220 to move closer to or away from the support block 1210 to quickly complete the clamping, locking and loosening of the front suspension component 10. In the clamping state, the horizontal and vertical displacement of the front suspension component 10 can be effectively restricted, and the torque generated by the bolt tightening operation during the assembly process can be resisted, avoiding the problem of displacement or loosening of the front suspension component 10. This not only ensures the assembly accuracy of the front suspension component 10, but also eliminates the production safety hazards caused by the loosening of the workpiece.

[0052] In optional embodiments of this application, the movable setting of the clamping block 1220 can be in various forms such as cylinder drive and thread drive. In order to further improve the convenience of clamping operation and the reliability of locking, the preferred solution of this embodiment is as follows.

[0053] like Figure 4 As shown, the fixing clamp 1200 also includes a base 1230, an operating handle 1240, and a pressure arm 1250. The base 1230 is fixedly connected to the support rod 1100. One end of the operating handle 1240 is hinged to the base 1230. One end of the pressure arm 1250 is hinged to the base 1230, and the middle part of the pressure arm 1250 is hinged to the middle part of the operating handle 1240. The pressure arm 1250 and the operating handle 1240 are perpendicular to each other. The clamping block 1220 is provided at the free end of the pressure arm 1250.

[0054] In this embodiment, when the operator turns the operating handle 1240 towards the support block 1210, the pressure arm 1250 swings downward synchronously, driving the clamping block 1220 to move towards the support block 1210 until the front suspension assembly 10 is clamped. At this time, the mechanism moves to the locked position, and the reverse force applied by the front suspension assembly 10 to the clamping block 1220 cannot push the mechanism to move in the opposite direction, thus achieving self-locking. This structure can realize one-click quick clamping and disassembly of the front suspension assembly 10, greatly shortening the clamping time. At the same time, the self-locking characteristic can significantly reduce the risk of workpiece loosening. Even under the severe vibration and torque generated by the high-torque bolt tightening operation, it can still maintain a stable clamping and locking state, ensuring the stability of the assembly process.

[0055] In actual production, the structural dimensions and clamping point heights of different models of front suspension components 10 vary. In order to improve the versatility of this assembly table 100 and adapt to the assembly requirements of front suspension components 10 of different specifications, this embodiment preferably sets an adjustable connection structure to realize flexible adjustment of the position of the clamping block 1220. The specific solution is as follows.

[0056] like Figure 4 As shown, the clamping block 1220 is connected to the pressure arm 1250 via a threaded adjusting block 1300, and the positions of the threaded adjusting block 1300 and the pressure arm 1250 are adjustable.

[0057] The relative position of the clamping block 1220 to the pressure arm 1250 can be flexibly adjusted by the threaded adjustment block 1300, thereby adjusting the clamping distance and clamping height between the clamping block 1220 and the support block 1210, adapting to the clamping requirements of front suspension components 10 with different thicknesses and sizes, and completing the assembly of multiple models of products without changing the tooling, greatly improving the versatility and applicability of the tooling table 110.

[0058] To further optimize the convenience and stability of adjustment, this embodiment provides a preferred implementation structure of the threaded adjusting block 1300, as detailed below.

[0059] like Figure 4 As shown, the threaded adjusting block 1300 includes a screw 1310, a nut 1320, and a limiting block 1330. The lower end of the screw 1310 is fixedly connected to the clamping block 1220; the upper end of the screw 1310 is movably connected to the limiting block 1330; and the nut 1320 passes through the screw 1310 and is screwed onto the upper and lower sides of the limiting block 1330 so that the limiting block 1330 is clamped and fixed to the end of the pressure arm 1250.

[0060] In this embodiment, the limiting block 1330 includes an upper limiting block and a lower limiting block arranged opposite each other. Both the upper and lower limiting blocks are movably sleeved on the outside of the screw 1310. Two nuts 1320 are screwed onto the screw 1310 from the upper and lower sides respectively, clamping and fixing the upper and lower limiting blocks to form a clamping structure, stably clamped at the end of the pressure arm 1250. Optionally, the end of the pressure arm 1250 is provided with a strip-shaped groove for the screw 1310 to pass through, and the strip-shaped groove extends along the length direction of the pressure arm 1250. Therefore, this structure can achieve position adjustment in two dimensions: First, by turning the nut 1320, the vertical position of the screw 1310 relative to the pressure arm 1250 can be adjusted, thereby adjusting the vertical height of the clamping block 1220 to adapt to front suspension components 10 of different thicknesses; Second, the screw 1310 can slide horizontally along the strip groove on the pressure arm 1250 to adjust the horizontal clamping position of the clamping block 1220 to adapt to front suspension components 10 of different widths and different clamping points, further improving the adaptability and adjustment flexibility of the tooling.

[0061] like Figure 4 As shown, optionally, the support rod 1100 includes an integrated first sub-rod 1110 and a second sub-rod 1120, wherein the upper end of the first sub-rod 1110 is used to fix the support block 1210, and the upper end of the second sub-rod 1120 is used to fix the base 1230; the first sub-rod 1110 and the second sub-rod 1120 share the same base 1130, and the base 1130 is fixedly connected to the table surface of the tooling table 110.

[0062] In this embodiment, the first sub-rod 1110 and the second sub-rod 1120 are separately configured, respectively connecting the support block 1210 and the base 1230 of the fixing clamp 1200. This allows the supporting force of the support block 1210 and the clamping force of the clamping block 1220 to be transferred to the two independent sub-rods, avoiding structural deformation caused by force concentration and improving the stability of clamping and support. At the same time, the first sub-rod 1110 and the second sub-rod 1120 share the same base 1130, which can greatly simplify the assembly process of the support rod 1100 and the workbench 110. Only the base 1130 needs to be fixed once to complete the installation of the entire support rod 1100, improving the assembly efficiency of the tooling.

[0063] like Figure 3 As shown, optionally, the connection between the first sub-rod 1110 and / or the second sub-rod 1120 and the base 1130 is provided with a reinforcing rib 1140.

[0064] In this embodiment, the reinforcing rib 1140 adopts a triangular rib plate structure, which is welded or integrally set between the side wall of the sub-rod and the upper surface of the base 1130. The two right-angled sides of the triangular rib plate are tightly fitted to the outer wall of the sub-rod and the upper surface of the base 1130, respectively. The reinforcing rib 1140 can effectively improve the structural strength and torsional resistance of the connection between the sub-rod and the base 1130, avoid bending and deformation of the sub-rod due to excessive force during clamping, further improve the load-bearing capacity and structural stability of the support rod 1100, and extend the service life of the tooling.

[0065] like Figure 4 As shown, optionally, a connecting plate 1150 is provided between the first sub-rod 1110 and the second sub-rod 1120, and the first sub-rod 1110, the second sub-rod 1120 and the connecting plate 1150 are integrally formed; the connecting plate 1150 is provided with a hollow opening 1151.

[0066] The connecting plate 1150 is laterally connected between the first sub-rod 1110 and the second sub-rod 1120, enabling the two sub-rods to form an integral frame structure. This significantly improves the overall structural rigidity and torsional resistance of the support rod 1100, preventing relative swaying of the first sub-rod 1110 or the second sub-rod 1120 during clamping operations and ensuring the clamping accuracy and operational stability of the fixing clamp 1200. Simultaneously, the hollowed-out opening 1151 on the connecting plate 1150 effectively reduces the overall weight of the support rod 1100 without affecting structural strength, lowering the material cost of the tooling. It also disrupts the vibration transmission path of the support rod 1100, offsetting excess vibration generated during assembly and preventing resonance between the first sub-rod 1110 and the second sub-rod 1120, further enhancing the stability of the tooling operation.

[0067] To further improve the support stability of the front suspension assembly 10, distribute the support force of the front suspension assembly 10, and avoid excessive force on a single point leading to workpiece deformation, this embodiment adds an auxiliary support structure to the table surface of the tooling table 110. The specific solution is as follows.

[0068] like Figure 3 As shown, the tooling table 110 is also provided with a support rod 1400. The bottom of the support rod 1400 is fixedly connected to the table surface, and the top of the support rod 1400 is provided with a support groove 1410.

[0069] The support rod 1400 cooperates with the support rod 1100 to provide multi-point auxiliary support for multiple stress points of the suspended front suspension assembly 10. This effectively disperses the self-weight load and assembly operation load of the front suspension assembly 10, preventing deformation of the front suspension assembly 10 due to excessive stress at a single point and ensuring the structural accuracy of the workpiece. Optionally, the upper surface shape of the support groove 1410 is conformally adapted to the shape of the corresponding support part of the front suspension assembly 10 to be processed, which can increase the support contact area, reduce the contact pressure, and at the same time play a pre-positioning role for the front suspension assembly 10, further improving the stability of the workpiece placement and avoiding the problem of workpiece slippage during assembly.

[0070] Optionally, the workbench 110 has a soft pad on its surface.

[0071] In this embodiment, the soft padding layer is preferably made of soft padding film, which is completely laid on the entire surface of the tooling table 110. During the assembly operation, it can buffer and protect the bolts, tools and placed parts from falling, avoid the parts from directly contacting the metal table surface and causing bumps and scratches, and ensure the surface quality and assembly accuracy of the front suspension component 10 parts.

[0072] The legs of the tooling table 110 are fixedly connected to the ground by expansion bolts 1500.

[0073] In this embodiment, the expansion bolt 1500 is preferably a core-driven expansion bolt, which rigidly fixes each leg of the tooling table 110 to the ground. This can effectively improve the overall anti-overturning and anti-torsion performance of the tooling table 110, and prevent the tooling table 110 from shifting or shaking due to the high torque bolt tightening operation during the assembly process. This provides a stable working reference for the assembly operation of the front suspension component 10, and further ensures the assembly accuracy and operational safety.

[0074] like Figure 5 and Figure 6As shown, the transfer vehicle 200 disclosed in this application embodiment includes a frame 2100. The frame 2100 is provided with a multi-layer front suspension positioning mechanism 2200 along the longitudinal direction. The frame 2100 has an opening on one side, and the front suspension positioning mechanism 2200 is disposed in the opening. The front suspension positioning mechanism 2200 includes a support bracket 2210 and an angle retaining bracket 2220. The upper surface of the support bracket 2210 is arc-shaped to support the main body 201a of the front suspension assembly 10. The upper surface of the angle retaining bracket 2220 is flat to support the steering knuckle 201b of the front suspension assembly 10, thereby limiting the rotation angle of the front suspension assembly 10.

[0075] In this embodiment, the frame 2100 is provided with a multi-layer front suspension positioning mechanism 2200 along the longitudinal direction, which can realize the multi-layer stacking of the front suspension components 10. This significantly increases the storage capacity of the front suspension components 10 within a limited floor area, effectively reducing the storage space occupied in the workshop, while also reducing the frequency of transfer operations and improving production flow efficiency. An opening is provided on one side of the frame 2100, forming a single-sided open structure without the obstruction of side rods. This allows the production line's robotic arms or cantilever cranes to directly extend into the frame 2100 to complete the picking and placing of the front suspension components 10 without additional avoidance operations, greatly improving the convenience and efficiency of loading and unloading. The front suspension positioning mechanism 2200 achieves stable positioning of the front suspension assembly 10 through the cooperation of the bearing bracket 2210 and the angle holding bracket 2220. The upper surface of the bearing bracket 2210 is arc-shaped, which conforms to the outer circular contour of the main body 201a (i.e., the front axle spindle) of the front suspension assembly 10, thereby increasing the contact area with the spindle, reducing the contact pressure, and preventing scratches on the spindle surface. At the same time, it provides stable support and pre-positioning for the front suspension assembly 10. The upper surface of the angle holding bracket 2220 is flat and is used to support the steering knuckles 201b at both ends of the front suspension assembly 10. It can effectively restrict the circumferential rotation of the front suspension assembly 10 around the spindle, preventing the front suspension assembly 10 from rolling or shifting during storage and transportation. The cooperation of the two mechanisms can achieve full-degree-of-freedom positioning of the front suspension assembly 10, ensuring the stability of the storage and transportation process, preventing workpiece collision damage, and ensuring the assembly accuracy of the parts.

[0076] like Figure 5 and Figure 6 As shown, two sets of front suspension positioning mechanisms 2200 are provided laterally on each layer of the frame 2100, and the two sets of front suspension positioning mechanisms 2200 avoid each other.

[0077] In this embodiment, each layer of the frame 2100 is provided with two sets of front suspension positioning mechanisms 2200, which can simultaneously support two sets of front suspension components 10 in a single layer, further improving the storage density and carrying capacity of the transfer vehicle 200. At the same time, the two sets of front suspension positioning mechanisms 2200 are arranged in a staggered manner to avoid structural interference when the two sets of front suspension components 10 are placed. While ensuring storage capacity, the overall width of the frame 2100 can be effectively controlled, further reducing space occupation.

[0078] In this application, the specific structural forms of the frame 2100, the load-bearing bracket 2210 and the angle-holding bracket 2220 can be flexibly set according to actual usage requirements. In order to further optimize the structural strength, ease of use and space utilization of the transfer vehicle 200, this embodiment provides the following preferred implementation scheme.

[0079] First, let's explain the structure of the 2100 frame, such as... Figure 5 and Figure 6 As shown, the frame 2100 includes four longitudinally arranged columns 2110. Each layer of the frame 2100 includes: two short rods 2120 symmetrically arranged along the width direction; an opening rod 2130 located on both sides of the opening of the frame 2100; and a long rod 2140 located on the opposite side of the opening rod 2130.

[0080] In this embodiment, the frame 2100 adopts a frame-type steel frame structure welded from structural steel. Four longitudinal columns 2110 serve as the main load-bearing components, and together with the short rods 2120, open rods 2130, and long rods 2140 of each layer, a stable shelf structure is formed. While ensuring the overall structural strength and load-bearing capacity, the overall weight of the frame 2100 is significantly reduced, thus lowering manufacturing costs. At the same time, the open rods 2130 form an open opening on one side of the frame 2100, without any lateral rods obstructing the view, providing ample operating space for the loading and unloading of the front suspension components 10, further improving the convenience of loading and unloading. The frame structure allows for standardized processing of multi-layer structures, making it easy to adjust the number of layers according to actual storage needs and adapt to different production scenarios.

[0081] Based on the above-mentioned frame-type vehicle frame 2100 structure, in order to achieve mutual avoidance between the two sets of front suspension positioning mechanisms 2200 and maximize the utilization of the internal space of the vehicle frame 2100, this embodiment optimizes the arrangement of the two sets of front suspension positioning mechanisms 2200 in the same layer, as follows.

[0082] like Figure 5 and Figure 6 As shown, the support bracket 2210 is located at the end of the open rod 2130; the angle holding bracket 2220 extends from the middle of the short rod 2120 to the opposite side.

[0083] In this embodiment, the support bracket 2210 of the front suspension positioning mechanism 2200 is located at the end of the open rod 2130, which can make full use of the space in the width direction of the frame 2100, so that the placement position of the front suspension assembly 10 and the other front suspension positioning mechanism 2200 form the maximum distance, avoiding structural interference when the two sets of front suspension assemblies 10 are placed; the angle holding bracket 2220 extends from the middle of the short rod 2120 to the opposite side of the frame 2100, which can accurately support the steering knuckle part 201b of the corresponding front suspension assembly 10, effectively restricting the circumferential rotation of the front suspension assembly 10 around the main shaft, ensuring the stability of placement. At the same time, the extended structure can be adapted to front suspension assemblies 10 of different lengths, improving the versatility of the transfer vehicle 200.

[0084] Furthermore, such as Figure 5 and Figure 6 As shown, in another set of front suspension positioning mechanisms 2200, the bearing bracket 2210 extends from the middle of the long rod 2140 to the opposite side; the angle holding bracket 2220 is provided on the long rod 2140.

[0085] In this embodiment, the bearing bracket 2210 of the front suspension positioning mechanism 2200 extends from the middle of the long rod 2140 toward the opening side, and is staggered with the angle-maintaining bracket 2220 extending from the middle of the short rod 2120. The two are not on the same straight line, which completely avoids structural interference. The two sets of front suspension components 10 can be placed synchronously within the limited width of the frame 2100. The angle-maintaining bracket 2220 is directly set on the long rod 2140, which can maximize the distance between the two sets of front suspension components 10 in the length direction of the frame 2100, further avoiding collisions between the front suspension components 10. At the same time, it can effectively control the overall width of the frame 2100, reduce the footprint of the transfer vehicle 200, and improve the utilization rate of workshop space.

[0086] like Figure 5 and Figure 6 As shown, optionally, in each set of front suspension positioning mechanisms 2200, the load-bearing axis directions of the load-bearing bracket 2210 and the angle-holding bracket 2220 are perpendicular to each other.

[0087] In this embodiment, the bearing axis of the bearing bracket 2210 is parallel to the axis of the main shaft of the front suspension assembly 10, and the bearing axis of the angle-holding bracket 2220 is perpendicular to the axis of the main shaft. The arrangement of the bearing axes of the two is perpendicular to each other, so that when the main shaft of the front suspension assembly 10 is placed on the bearing bracket 2210, the steering knuckle portions 201b at both ends are stably supported on the angle-holding bracket 2220. Even if the main shaft tends to roll circumferentially on the arc-shaped bearing bracket 2210, the steering knuckle portions 201b will be effectively limited by the angle-holding bracket 2220, completely preventing the circumferential rotation of the main shaft. The two work together to form a double limit, further improving the stability of the placement of the front suspension assembly 10 and avoiding the problem of workpiece displacement or falling during the transfer process.

[0088] Optionally, such as Figure 5 and Figure 6 As shown, the upper surface of the angle holding bracket 2220 is provided with vertical guard wings 2221 on both sides, and the upper end of the guard wings 2221 is provided with a slope 2222.

[0089] In this embodiment, the guard wings 2221 are symmetrically arranged on both sides of the upper surface of the angle holding bracket 2220, extending vertically upward. The height of the guard wings 2221 is slightly lower than the height of the steering knuckle portion 201b, so that it will not obstruct the placement of the steering knuckle and can form a lateral limiting space. The inclined surface 2222 at the upper end of the guard wings 2221 is inclined outward to form a guide structure. Therefore, the vertical guard 2221 can provide lateral restraint for the steering knuckle 201b supported on the angle holding bracket 2220, preventing the steering knuckle from shifting or deviating due to vibration during the movement of the transfer vehicle 200, further improving the stability of the front suspension assembly 10 and preventing the steering knuckle from being damaged by collision with other components; the upper inclined surface 2222 can serve as a guide. When the robot or lifting device places the front suspension assembly 10, even if there is a slight deviation in the placement position of the steering knuckle, the guide effect of the inclined surface 2222 can ensure that the steering knuckle slides accurately onto the supporting plane of the angle holding bracket 2220, greatly improving the convenience and accuracy of loading and unloading, while avoiding scratches on parts caused by hard contact, thus balancing stability and ease of operation.

[0090] Optionally, the bottom of the frame 2100 is provided with casters 2300.

[0091] In this embodiment, universal wheels 2300 are provided at the four corners of the bottom of the frame 2100, which can realize the flexible movement of the transfer vehicle 200 in all directions. The front suspension component 10 can be transferred between various processes in the workshop without relying on a forklift, which greatly simplifies the transfer process, reduces the transfer cost, and adapts to the flow requirements of flexible production lines.

[0092] Optionally, the caster wheel 2300 is equipped with a locking mechanism.

[0093] In this embodiment, the locking structure provided with the caster wheel 2300 can quickly lock the caster wheel 2300 after the transfer vehicle 200 moves to the target workstation, so as to prevent the transfer vehicle 200 from accidentally slipping during storage and loading / unloading, ensuring the stability and safety of the operation process, so that the transfer vehicle 200 can be used for flexible transfer or as a fixed storage rack, realizing multiple uses of one vehicle and improving the practicality of the tooling.

[0094] Optionally, a pusher structure 2400 is provided on the outer side of the frame 2100.

[0095] In this embodiment, the pusher structure 2400 is symmetrically arranged on two short rods 2120 on the opening side of the frame 2100. Operators can push the transfer vehicle 200 to move from both sides of the frame 2100, which greatly improves the convenience of operation. At the same time, the pusher structure 2400 is arranged on the short rods 2120, which will not block the opening on one side of the frame 2100 and will not affect the loading and unloading of the front suspension component 10, thus taking into account both the convenience of operation and the efficiency of loading and unloading.

[0096] like Figure 7 and Figure 8 As shown, the mounting fixture 300 provided in this embodiment includes a fixture body 3100, on which the following are provided:

[0097] The load-bearing bracket 3110 is located at the center of the clamp body 3100;

[0098] Pads 3200 are symmetrically arranged on both sides of the load-bearing bracket 3110;

[0099] The first power unit 3300 is connected to the claw 3200 and is used to drive the claw 3200 to open and close relative to the load-bearing bracket 3110.

[0100] In this embodiment, the load-bearing bracket 3110 is used to bear the main weight of the front suspension component 10 in the vertical direction, providing stable bottom support for the front suspension component 10 and solving the core pain point of requiring manual lifting of the load throughout the traditional assembly process. After the load-bearing bracket 3110 completes the support and positioning of the front suspension component 10, the symmetrically arranged claws 3200, driven by the first power unit 3300, open and close relative to the load-bearing bracket 3110, clamping and limiting the front suspension component 10 from both sides in the lateral direction. Together with the load-bearing bracket 3110, they form an omnidirectional positioning structure of "bottom support + lateral clamping", which can quickly grab the front suspension component 10 from the transfer rack and achieve automatic centering positioning. There is no need for multiple people to lift and adjust the posture. A single person can complete the stable clamping, posture adjustment and precise alignment installation of the front suspension component 10 through the fixture, which greatly reduces the labor intensity of the operators, effectively improves the hole alignment accuracy and assembly efficiency, and completely solves the problem of requiring multiple people to cooperate in traditional assembly.

[0101] like Figure 7 and Figure 8 As shown, there are two load-bearing brackets 3110, which are symmetrically arranged at the center of the clamp body 3100; the free end of the load-bearing bracket 3110 is provided with a contour block 3120 that is adapted to the shape of the front suspension assembly 10.

[0102] In this embodiment, the two load-bearing brackets 3110 are symmetrically arranged along the central axis of the clamp body 3100, which makes the support force points of the front suspension component 10 symmetrically distributed. During the support process, the front suspension component 10 is subjected to more uniform force, effectively avoiding the problems of skewing and shaking during gripping, transportation and alignment, and greatly improving the stability of the clamping state. The contour of the contour block 3120 is perfectly matched with the shape of the support part of the front suspension component 10, which can increase the contact area with the front suspension component 10, realize the precise contour positioning of the front suspension component 10, and prevent the front suspension component 10 from slipping relative to the support process. At the same time, the upper surface of the contour block 3120 is made of soft silicone material, which can buffer the rigid contact between the clamp and the front suspension component 10, avoid scratching the surface coating and machined surface of the front suspension component 10, and also increase the friction coefficient of the contact surface, further improving the reliability of clamping and positioning.

[0103] Optionally, such as Figure 7 and Figure 8 As shown, the clamp body 3100 is arranged vertically, and a horizontal mounting plate 3400 is provided at the lower end of the clamp body 3100; the load-bearing bracket 3110 is fixedly connected to the mounting plate 3400; the first power unit 3300 is provided on the mounting plate 3400, and the claw 3200 is slidably connected to the mounting plate 3400.

[0104] In this embodiment, the mounting plate 3400 serves as the bearing base at the lower end of the fixture, providing a unified mounting reference for the load-bearing bracket 3110, the first power unit 3300, and the claw 3200, ensuring the positional accuracy of each moving component. The first power unit 3300 is preferably a cylinder, using compressed air commonly used in vehicle assembly workshops as its power source. It features fast response, stable output force, and simple and convenient control logic, adapting to the high-frequency reciprocating operation requirements of the assembly line. The first power unit 3300 is fixedly mounted on the mounting plate 3400 and can directly drive the claw 3200 to perform horizontal reciprocating sliding relative to the mounting plate 3400, thereby stably realizing the opening and closing action of the claw 3200. The load-bearing bracket 3110 is fixedly connected to the mounting plate 3400, ensuring the rigidity and stability of the support structure. It will not deform or shift when bearing the weight of the front suspension component 10, providing a reliable support reference for the front suspension component 10 and ensuring the positional accuracy during clamping and alignment.

[0105] It should be noted that the specific implementation of the sliding opening and closing of the claw 3200 relative to the mounting plate 3400 is not limited. This embodiment provides a preferred implementation as follows.

[0106] like Figure 7 and Figure 8 As shown, the mounting plate 3400 is provided with a slide rail 3410, and the base of the claw 3200 is provided with a slider 3210. The claw 3200 is slidably connected to the slide rail 3410 through the slider 3210; the output end of the first power unit 3300 is connected to the slider 3210.

[0107] In this embodiment, the slide rail 3410 is fixedly laid on the front of the mounting plate 3400, and the extension direction of the slide rail 3410 is consistent with the opening and closing movement direction of the claw 3200. The claw 3200 forms a high-precision linear sliding pair with the slide rail 3410 through the slider 3210 at the base, providing precise linear guidance for the opening and closing movement of the claw 3200. The output end of the first power unit 3300 is fixedly connected to the slider 3210, and the power can be directly transmitted to the slider 3210, driving the claw 3200 to make a smooth reciprocating linear movement along the slide rail 3410, effectively reducing the frictional resistance and jamming risk during the movement, ensuring the synchronicity of the movement of the claws 3200 on both sides, thereby ensuring the positional accuracy of the opening and closing of the claw 3200, and realizing the precise clamping and centering positioning of the front suspension component 10.

[0108] It should be noted that in actual assembly operations, the front suspension component 10 being clamped may not be in a completely horizontal state, and the mounting surface of the frame 2100 to be assembled also has certain positional and angular tolerances. In order to solve the adaptive alignment problem of the above-mentioned installation error, this application further provides the following preferred solution.

[0109] like Figure 7 and Figure 8 As shown, the clamp body 3100 is hinged to the mounting plate 3400, wherein a first elastic element is provided at the hinge point between the clamp body 3100 and the mounting plate 3400.

[0110] In this embodiment, the clamp body 3100 and the mounting plate 3400 form a hinge structure through the rotating shaft 3420, allowing the mounting plate 3400 and the clamping mechanisms such as the load-bearing bracket 3110 and the claw 3200 mounted on it to swing left and right at a small angle relative to the clamp body 3100 around the rotating shaft 3420. This adaptively compensates for the angle error caused by the non-horizontal placement of the front suspension component 10 and the non-absolute horizontality of the mounting surface of the frame 2100, achieving flexible alignment in the roll direction and reducing the difficulty of hole alignment. The first elastic element provided at the hinge provides elastic restoring force and damping buffer when the mounting plate 3400 swings relative to the clamp body 3100. This ensures that the mounting plate 3400 can automatically return to the initial reference position after the swing adjustment, and also maintains the stability of the clamping mechanism during the swing, avoiding irregular shaking and greatly improving the fault tolerance and smoothness of the assembly process.

[0111] It should be noted that the specific configuration and connection method of the first elastic element are not limited. This embodiment provides a preferred implementation method as follows.

[0112] like Figure 7 and Figure 8 As shown, a first elastic element is provided at the hinge joint between the clamp body 3100 and the mounting plate 3400, including:

[0113] The clamp body 3100 has a symmetrical first side wing 3130 at the hinge; the mounting plate 3400 has a symmetrical second side wing 3430 at the hinge; the first elastic element includes a pair of springs 3510, which are respectively disposed between the symmetrical first side wing 3130 and the second side wing 3430.

[0114] In this embodiment, the first side wing 3130 and the second side wing 3430 are arranged in a one-to-one correspondence and are symmetrically distributed on the left and right sides of the hinge rotation shaft 3420, respectively. A pair of springs 3510 are respectively installed between the first side wing 3130 and the second side wing 3430 on the same side. When the mounting plate 3400 swings to the left relative to the clamp body 3100 around the rotation shaft 3420, the spring 3510 on the left is compressed and the spring 3510 on the right is stretched. When the mounting plate 3400 swings to the right, the spring 3510 on the right is compressed and the spring 3510 on the left is stretched. The springs 3510 on both sides can provide elastic restoring force in both directions, so that the swing force of the mounting plate 3400 is more balanced and the restoring action is more stable, avoiding the problem of uneven wear and jamming caused by unilateral force.

[0115] Optionally, each spring 3510 has a guide post at its center, and the two ends of the guide post are respectively engaged with the corresponding first side wing 3130 and second side wing 3430 for limiting. This can effectively limit the radial deformation of the spring 3510 during compression and tension, prevent the spring 3510 from bending and becoming unstable, ensure that the elastic force of the spring 3510 is always transmitted in the preset direction, and greatly improve the working reliability and service life of the elastic mechanism.

[0116] The aforementioned first elastic element, in conjunction with the hinge structure, solves the problem of angle correction and flexible alignment in the roll direction of the front suspension assembly 10. In actual assembly operations, it is also necessary to adjust the pitch direction of the front suspension assembly 10 to adapt to the angle requirements of the high mounting position of the frame 2100. This embodiment provides a preferred implementation method as follows.

[0117] like Figure 7 and Figure 8 As shown, a connecting flange 3600 is hinged to the upper end of the clamp body 3100, and a pitch cylinder 3700 is connected between the clamp body 3100 and the connecting flange 3600.

[0118] In this embodiment, the connecting flange 3600 is used to fix and connect to external equipment such as hoisting equipment and robotic arms on the assembly line, providing an installation reference for the entire fixture. The upper end of the fixture body 3100 is hinged to the connecting flange 3600, allowing the fixture body 3100 to pitch and swing relative to the connecting flange 3600 around the hinge axis, providing the front suspension assembly 10 with a degree of freedom of movement in the pitch direction. The pitch cylinder 3700 is connected between the fixture body 3100 and the connecting flange 3600, providing assistance for the pitch swing of the fixture body 3100, balancing the overturning moment caused by the weight of the front suspension assembly 10, and enabling a single person to easily control the pitch swing adjustment of the fixture and the clamped front suspension assembly 10, accurately matching the pitch angle of the frame 2100 mounting position, completely solving the problem of the large weight of the front suspension assembly 10 and the difficulty of pitch adjustment, and greatly reducing the operational difficulty of high-position installation.

[0119] It should be noted that the specific connection method of the pitch cylinder 3700 is not limited. This embodiment provides a preferred implementation method as follows.

[0120] like Figure 7 and Figure 8 As shown, a connecting wing 3140 is fixedly provided on the fixture body 3100, wherein the base of the pitch cylinder 3700 is hinged to the connecting flange 3600, and the output end of the pitch cylinder 3700 is hinged to the connecting wing 3140.

[0121] In this embodiment, the connecting wing 3140 is fixedly welded or bolted to the upper side wall of the fixture body 3100, providing a stable connection fulcrum for the output end of the pitch cylinder 3700. The base of the pitch cylinder 3700 is hinged to the connecting flange 3600, and the output end is hinged to the connecting wing 3140, so that both ends of the pitch cylinder 3700 have rotational freedom. During the pitch swing of the fixture body 3100 driven by the cylinder extension and retraction, it can adaptively adjust its own angle, completely avoid motion interference, and ensure that the pitch adjustment action is smooth and without jamming throughout the process. At the same time, the hinged connection structure can realize stepless fine adjustment of the pitch angle, adapt to the pitch angle requirements of different vehicle models and different installation positions, and greatly improve the versatility of the fixture.

[0122] Furthermore, such as Figure 7 and Figure 8 As shown, the fixture body 3100 is provided with an operating handle 3800, and the operating handle 3800 is provided with a valve box 3900. The valve box 3900 is connected to the pitch cylinder 3700 and the first power unit 3300.

[0123] In this embodiment, the operating handle 3800 is fixedly installed in the middle area of ​​the fixture body 3100, which conforms to the ergonomic design and makes it easy for operators to hold and control the movement and posture adjustment of the entire fixture. The valve box 3900 integrates a pneumatic control valve group. The operation panel of the valve box 3900 is equipped with multiple buttons corresponding to control functions. The valve box 3900 is connected to the pitch cylinder 3700 and the first power unit 3300 through pneumatic pipelines to realize the transmission of signals and power. Operators can use the buttons on the valve box 3900 to control the extension and retraction of the first power unit 3300 with one hand to realize the clamping and releasing action of the claw 3200, as well as control the extension and retraction of the pitch cylinder 3700 to realize the adjustment of the pitch angle of the front suspension component 10. The operation is centralized, convenient, intuitive and efficient, and truly realizes the entire process of gripping, transferring, aligning and installing the front suspension component 10 by a single person, further improving assembly efficiency.

[0124] In summary, this invention discloses a front suspension installation production line for the production and assembly of a front suspension component 10 for automobiles. The production line includes an assembly table 100, a transfer line 400, a transfer vehicle 200, and an installation fixture 300 arranged sequentially. The assembly table 100 supports and secures the front suspension component 10 to be assembled; the transfer line 400 transports the assembled front suspension component 10 from the assembly table 100 to the transfer vehicle 200; the transfer vehicle 200 receives and transports the front suspension component 10 to the installation station; the installation fixture 300 is connected to a positioning column 320 via a power assist mechanism 310, allowing it to rotate freely within a preset angle to clamp and install the front suspension component 10. This invention integrates the assembly, transfer, and installation processes, achieving efficient flow of the entire front suspension component 10 process. A single person can complete all operations, significantly reducing labor intensity, improving assembly efficiency and precision, and meeting the operational requirements of truck assembly lines.
