Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a chassis structure for limiting and supporting the side assembly. Background Technology

[0002] During the production and assembly of automotive side panel assemblies, the side panel assemblies are prone to displacement or swaying due to their large size and complex structure. Existing support structures often suffer from insufficient rigidity, low limiting accuracy, or poor adaptability, making it difficult to stably constrain their posture. This can easily lead to increased assembly errors and reduced production efficiency. Therefore, there is an urgent need for a dedicated side panel assembly limiting support chassis structure to improve this situation.

[0003] In existing technologies, the traditional automotive side panel assembly processing chassis is rigidly bolted to the ground and the platform at both ends, which makes it easy for vibration to be transmitted to the root of the outriggers, causing stress concentration and shortening the equipment life. At the same time, while the rigid design in existing technologies can ensure processing accuracy, it lacks buffering, and while the flexible design can improve flexibility, it sacrifices accuracy, creating a contradiction between accuracy and flexibility, and between stability and life.

[0004] To address this, a chassis structure for limiting and supporting the side panel assembly is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a chassis structure for limiting and supporting the side panel assembly, which can solve the existing problems of contradiction between precision and flexibility, and stability and lifespan.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a base frame structure for limiting and supporting a side panel assembly, comprising a platform, an elastic compensation mechanism movably connected to the bottom of the platform, a support leg movably connected to the bottom of the elastic compensation mechanism, a circumferential fixing mechanism movably connected to the outer side of the bottom of the support leg, the circumferential fixing mechanism comprising a hollow support, the hollow support being sleeved on the outer side of the bottom of the support leg, four tripods slidably connected to the top of the hollow support, and the four tripods being respectively arranged on the corresponding sides of the outer walls around the support leg, and a co-directional drive assembly movably connected to the bottom of the tripods and the inner side of the hollow support.

[0007] Preferably, the elastic compensation mechanism includes a telescopic support column, which is fixedly connected to the top of the outrigger, and the platform is fixedly connected to the top of the telescopic support column. A telescopic guide rod is rotatably connected to the outer side of the outrigger, and the other end of the telescopic guide rod is rotatably connected to the bottom of the platform.

[0008] Preferably, a first compression spring is fixedly connected to the inner side of the telescopic support.

[0009] Preferably, a second compression spring is sleeved on the outer side of the telescopic guide rod.

[0010] Preferably, the co-directional drive assembly includes a servo motor, which is fixedly connected to the inner side of the hollow support. A drive gear is fixedly connected to the output end of the servo motor, and a linkage gear is meshed with the outer side of the drive gear. The linkage gear is rotatably connected to the bottom of the inner side of the hollow support, and a guide plate is fixedly connected to the top of the linkage gear. The guide plate is rotatably connected to the inner side of the hollow support.

[0011] Preferably, a linkage column is movably connected to the inner side of the guide plate, a linkage rod is fixedly connected to the top of the linkage column, the linkage rod is fixedly connected to the bottom of the tripod, and the linkage rod is slidably connected to the top of the inner side of the hollow support.

[0012] Preferably, a support plate is fixedly connected to the outer side of the support leg.

[0013] Preferably, a hydraulic buffer cylinder is fixedly connected to the top of the support plate, and the other end of the hydraulic buffer cylinder is fixedly connected to the bottom of the platform.

[0014] Preferably, a mounting plate is fixedly connected to the outer side of the hollow support.

[0015] Preferably, the inner side of the mounting plate is bolted with fastening bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application, by setting up a ring-fixing mechanism, can reserve space for small displacement compensation during processing to reduce vibration transmission. During processing, a servo motor can be started, which drives the guide plate to rotate through the drive gear and linkage gear. The guide groove of the guide plate will push the linkage column and linkage rod, so that the tripod can form a triangular support by ringing the legs from the four walls. This solves the problem that the traditional double-end rigid bolt connection causes vibration to be transmitted to the root of the legs, resulting in stress concentration and shortening the equipment life. It also avoids the drawbacks of existing rigid design lacking buffer and flexible design sacrificing accuracy. It balances the contradiction between processing accuracy and structural flexibility, and support stability and equipment life.

[0018] 2. This application, by setting up an elastic compensation mechanism, can install a telescopic support with a first compression spring embedded longitudinally between the outrigger and the platform, a telescopic guide rod distributed in a figure-eight pattern and fitted with a second compression spring, and a hydraulic buffer cylinder between the support plate inside the outrigger and the platform. This allows the platform to settle slightly under pressure, while the telescopic support extends and retracts longitudinally to push back, and the telescopic guide rod rotates and retracts to push back, thus quickly buffering and dispersing the pressure. The hydraulic buffer cylinder can also prevent the platform from settling significantly. This solves the potential problem in the above example where, after the outrigger and platform are independent, the platform may become unstable or settle under pressure due to a lack of effective buffering, affecting the operation. It achieves both pressure buffering and force dispersal, and ensures the stability of the operation process, avoiding interference with processing caused by insufficient buffering or excessive settlement.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A base frame structure for limiting and supporting a side panel assembly includes a platform 1. An elastic compensation mechanism 2 is movably connected to the bottom of the platform 1. A support leg 3 is movably connected to the bottom of the elastic compensation mechanism 2. A circumferential fixing mechanism 4 is movably connected to the outer side of the bottom of the support leg 3. The circumferential fixing mechanism 4 includes a hollow support 41, which is sleeved on the outer side of the bottom of the support leg 3. Four tripods 42 are slidably connected to the top of the hollow support 41, and the four tripods 42 are respectively arranged on the corresponding sides of the outer wall of the support leg 3. A co-directional drive assembly 43 is movably connected to the bottom of the tripods 42 and the inner side of the hollow support 41.

[0028] In this embodiment, the support legs 3 are not bolted to the platform 1, but have two structures: First, each support leg 3 has a longitudinal telescopic support column 21 with an embedded first compression spring 23 between its top and the bottom of the platform 1. Second, each support leg 3 has two sides of its outer wall near the platform 1 that are rotatably connected to telescopic guide rods 22. The other end of these telescopic guide rods 22 is rotatably connected to the center of the bottom periphery of the platform 1. Each side also forms a telescopic guide rod 22 structure with an outer second compression spring 24 arranged in a figure-eight pattern. Therefore, when the platform 1 is pressed, it will sink slightly. The longitudinal telescopic support column 21 with an embedded first compression spring 23 will extend and retract longitudinally to push back, and the telescopic guide rods 22 will rotate and retract to push back, achieving quick buffering and decomposition. In addition, the support leg 3 also has a support plate 5 inside. There is a hydraulic buffer cylinder 6 between the support plate 5 and the platform 1 for hydraulic auxiliary buffering to avoid affecting the operation.

[0029] Specifically, such as Figure 4 , Figure 5 As shown, the elastic compensation mechanism 2 includes a telescopic support column 21, which is fixedly connected to the top of the support leg 3. The platform 1 is fixedly connected to the top of the telescopic support column 21. A telescopic guide rod 22 is rotatably connected to the outside of the support leg 3, and the other end of the telescopic guide rod 22 is rotatably connected to the bottom of the platform 1.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, a first compression spring 23 is fixedly connected to the inner side of the telescopic support 21.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, a second compression spring 24 is sleeved on the outer side of the telescopic guide rod 22.

[0032] In this embodiment, the support legs 3 are not bolted to the platform 1, but have two structures. First, each support leg 3 has a longitudinal telescopic support column 21 with an embedded first compression spring 23 between its top and the bottom of the platform 1. Second, each support leg 3 has two sides of its outer wall near the platform 1 that are rotatably connected to telescopic guide rods 22. The other end of these telescopic guide rods 22 is rotatably connected to the center of the bottom periphery of the platform 1. Each side also forms a telescopic guide rod 22 structure with an outer second compression spring 24 arranged in a figure-eight pattern. Therefore, when the platform 1 is pressed, it will sink slightly. The longitudinal telescopic support column 21 with an embedded first compression spring 23 will extend and retract longitudinally to push back, and the telescopic guide rods 22 will rotate and retract to push back, achieving quick buffering and decomposition. In addition, the support leg 3 also has a support plate 5 inside. There is a hydraulic buffer cylinder 6 between the support plate 5 and the platform 1 for hydraulic auxiliary buffering to avoid affecting the operation.

[0033] Specifically, such as Figure 2 , Figure 3As shown, the co-directional drive assembly 43 includes a servo motor 4301, which is fixedly connected to the inner side of the hollow support 41. The output end of the servo motor 4301 is fixedly connected to a drive gear 4302. The outer side of the drive gear 4302 is meshed with a linkage gear 4303. The linkage gear 4303 is rotatably connected to the bottom of the inner side of the hollow support 41. The top of the linkage gear 4303 is fixedly connected to a guide plate 4304, which is rotatably connected to the inner side of the hollow support 41.

[0034] Specifically, such as Figure 2 , Figure 3 As shown, a linkage column 4305 is movably connected to the inner side of the guide plate 4304, and a linkage rod 4306 is fixedly connected to the top of the linkage column 4305. The linkage rod 4306 is fixedly connected to the bottom of the tripod 42, and the linkage rod 4306 is slidably connected to the top of the inner side of the hollow support 41.

[0035] In this embodiment: by activating the servo motor 4301 inside the hollow support 41, the drive gear 4302 at the output end of the servo motor 4301 can rotate, thereby driving the linkage gear 4303 meshing with the outer side of the drive gear 4302. The linkage gear 4303 then drives the guide disk 4304 coaxially connected to its top to rotate. There are four sets of guide grooves on the inner side of the guide disk 4304. The linkage column 4305 inside each guide groove is squeezed and guided by the rotating guide groove and moves along the groove, thereby driving the linkage rod 4306 fixedly connected to the top of the linkage column 4305 to move. Since the linkage rod 4306 is fixedly connected to the tripod 42 at the top of the hollow support 41, it is also limited by the sliding groove at the top of the hollow support 41, ultimately achieving the effect that the tripod 42 in the four directions of the support leg 3 slides inward at the same time and contacts the support leg 3 from the four walls.

[0036] Specifically, such as Figure 4 As shown, a support plate 5 is fixedly connected to the outer side of the support leg 3.

[0037] Specifically, such as Figure 4 As shown, a hydraulic buffer cylinder 6 is fixedly connected to the top of the support plate 5, and the other end of the hydraulic buffer cylinder 6 is fixedly connected to the bottom of the platform 1.

[0038] In this embodiment: to prevent significant settlement, a support plate 5 is installed inside the outrigger 3, and a hydraulic buffer cylinder 6 is installed between the support plate 5 and the platform 1 for hydraulic auxiliary buffering to avoid affecting the operation.

[0039] Specifically, such as Figure 1 As shown, a mounting plate 7 is fixedly connected to the outer side of the hollow support 41.

[0040] Specifically, such as Figure 1 As shown, fastening bolts 8 are bolted to the inner side of the mounting plate 7.

[0041] In this embodiment, the hollow support 41 can be bolted to the ground by the mounting plate 7 and the fastening bolts 8.

[0042] Working Principle: When processing the side panel assembly structure for automobiles, the typical limiting support structure is a relatively flat processing table 1. The main base structure of this processing table 1 is usually four sets of support legs 3. In the prior art, the support legs 3 are usually bolted to both ends of the table 1 and the ground to achieve a stable rigid connection. However, in this state, although rigid fixation can ensure accuracy, it is prone to stress concentration, such as vibration transmitted to the root of the support legs 3, which can shorten the life of the equipment. In addition, the existing flexible design can improve flexibility, but it sacrifices processing accuracy, creating a contradiction between accuracy and flexibility, stability and lifespan. To avoid the above situations, the support legs 3 are separated from the table 1. The support legs 3 are no longer bolted to the ground, but are located at the seat position of the support legs 3. A hollow support 41 is provided on the outer side of the device. This hollow support 41 is directly bolted to the ground and has a groove inside. The support leg 3 is sleeved on the inner side of the groove, allowing for small displacement compensation during processing and free adjustment after processing. In order to ensure its stability during processing, the servo motor 4301 located inside the hollow support 41 is started, which causes the drive gear 4302 located at the output end of the servo motor 4301 to rotate. This causes the linkage gear 4303 located on the outer side of the drive gear 4302 to drive, and the linkage gear 4303 drives the guide disk 4304 coaxially connected to its top to rotate. Four sets of guide grooves are provided on the inner side of the guide disk 4304. Each guide groove is movably connected to the inner side of a linkage column 4305. When the disc 4304 rotates, the guide groove will compress and guide the linkage column 4305 inside, causing it to move along the groove and drive the linkage rod 4306 fixedly connected to its top to move. Since the linkage rod 4306 is fixedly connected to the tripod 42 on the top of the hollow support 41 and is limited by the sliding groove on the top of the hollow support 41, the tripod 42 of the support leg 3 slides inward in all four directions at the same time, and contacts the support leg 3 from the four walls. The tripod 42 forms a triangular support on all four sides, which enhances stability and reduces vibration damage. Secondly, the support leg 3 and the platform 1 are not bolted together. Instead, the following structure is set on the opposite side of the support leg 3 and the platform 1. One is that a longitudinal telescopic support with a first compression spring 23 is set between the top of each support leg 3 and the bottom of the platform 1. The support consists of two parts: firstly, each leg 3 has a telescopic guide rod 22 rotatably connected to two sides of its outer wall near the platform 1; secondly, the other end of the telescopic guide rod 22 is rotatably connected to the center of the bottom periphery of the platform 1, forming a telescopic guide rod 22 structure with a figure-eight distributed outer second compression spring 24 on each side. In summary, when the platform 1 is pressed, it can be allowed to settle slightly. The telescopic support column 21 extends and retracts longitudinally and pushes back, while the telescopic guide rod 22 rotates, retracts, and pushes back, achieving quick buffering and decomposition. In order to prevent large-scale settlement, a support plate 5 is also provided inside the leg 3. A hydraulic buffer cylinder 6 is provided between the support plate 5 and the platform 1 for hydraulic auxiliary buffering to avoid affecting the operation. In summary, the optimization of the base frame structure used for the limit support of the side assembly is achieved.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
