Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, and in particular relates to a high-performance lightweight aluminum profile vehicle frame suspension device. Background Technology

[0002] In the automotive industry, especially in the fields of new energy vehicles and special vehicles, high-performance lightweight aluminum profile frames have become key components for improving energy efficiency and performance. These frames are usually made of high-strength aluminum alloy through extrusion processes and constructed using advanced connection technologies. Their core feature is that they have extremely high specific strength and specific stiffness, that is, while ensuring structural strength comparable to or higher than that of traditional steel frames, they achieve a significant reduction in weight, thereby effectively improving the vehicle's range, load capacity and dynamic response performance.

[0003] On the vehicle assembly line, the installation of the chassis is the first critical step in the final assembly process. The chassis suspension equipment plays a core role in this process. It is responsible for smoothly lifting the chassis from the conveyor line or storage station to the assembly chassis and performing multi-degree-of-freedom attitude adjustments to ensure alignment with chassis suspension points, powertrain and other components. The performance of the suspension equipment directly determines the positioning accuracy, docking efficiency and protection capability of the high-value chassis surface during chassis installation.

[0004] Existing high-performance lightweight aluminum profile frame suspension equipment still has some problems during use. For example, traditional suspension equipment uses rigid clamping, which can easily cause indentations on the thin aluminum profile surface under clamping force, damaging the workpiece. At the same time, rigid clamping is more sensitive to the dimensional tolerances and deformation of the frame, and frequent fine adjustments to compensate for positioning errors can easily exacerbate the shaking of the suspension equipment.

[0005] To address these issues, we provide a high-performance, lightweight aluminum profile vehicle frame suspension system. Utility Model Content

[0006] The purpose of this utility model is to provide a high-performance lightweight aluminum profile vehicle frame suspension device. By cooperating with the adjustment mechanism and the clamping mechanism, it solves the problem that existing high-performance lightweight aluminum profile vehicle frame suspension devices, which use rigid clamping, are prone to indentation on the surface of thin aluminum profiles under clamping force, thus damaging the workpiece.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a high-performance lightweight aluminum profile vehicle frame suspension device, comprising a moving track, an adjustment mechanism at the bottom of the moving track, a clamping mechanism at the bottom of the adjustment mechanism, the adjustment mechanism comprising a vertical box fixedly connected to the bottom of the moving track, an extension component disposed inside the vertical box, a rotating component disposed at the bottom of the vertical box, and an inclined component disposed at the bottom of the rotating component, the clamping mechanism comprising a fixed plate disposed at the bottom of the inclined component, a positioning plate fixedly connected to one side of the bottom of the fixed plate, and a clamping component disposed on one side of the fixed plate.

[0009] The present invention is further configured such that the extension assembly includes a first hydraulic cylinder fixedly connected inside the vertical box, a push plate fixedly connected to the output end of the first hydraulic cylinder, a magnetic suction rod fixedly connected to the bottom of the push plate, an electromagnet fixedly connected to the bottom of the vertical box, and a limiting rod fixedly connected to the bottom of the push plate.

[0010] The present invention is further configured such that the rotating assembly includes a connecting plate disposed at the bottom of the vertical box, a motor fixedly connected to the top of the connecting plate, and a rotating plate fixedly connected to the output end of the motor.

[0011] The present invention is further configured such that a circular groove is provided inside the connecting plate, a support wheel is slidably connected inside the circular groove, the bottom of the support wheel is fixedly connected to the top of the rotating plate, and a handle is fixedly connected to one side of the connecting plate.

[0012] The present invention is further configured such that the tilting component includes a connecting rod disposed on one side of the bottom of the vertical box, and a second hydraulic cylinder disposed on one side of the bottom of the vertical box. The bottom of the connecting rod is movably connected to the top of the fixed plate via a rotating shaft, and the output end of the second hydraulic cylinder is movably connected to the top of the fixed plate via a rotating shaft.

[0013] The present invention is further configured such that the clamping assembly includes a top contact plate fixedly connected to the bottom of the fixed plate, a third hydraulic cylinder fixedly connected to the top of the fixed plate, a clamping plate fixedly connected to the output end of the third hydraulic cylinder, and an airbag fixedly connected to one side of the clamping plate.

[0014] The present invention is further configured such that the number of airbags is three, and the three airbags are designed in a triangular shape.

[0015] This utility model has the following beneficial effects: Through the flexible clamping component, this utility model achieves non-destructive and stable gripping of the frame. The clamping mechanism first completes the initial positioning by contacting the side of the frame with the positioning plate. Then, the extension component drives the fixing plate to move down so that the top contact plate contacts the top of the frame. Immediately afterwards, the third hydraulic cylinder contracts and simultaneously triggers the triangularly arranged airbags to inflate, forming a coordinated clamping that wraps around the frame from the top and bottom. Through the combination of hydraulic drive and air pressure, the traditional rigid contact is transformed into a large-area flexible contact, which not only provides sufficient clamping force but also evenly distributes the pressure, thereby achieving the technical effect of effectively protecting the surface integrity of the lightweight aluminum profile and avoiding indentation damage.

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1 Please see Figures 1-5 This utility model is a high-performance lightweight aluminum profile vehicle frame suspension device, including a moving track 1, an adjustment mechanism 2 at the bottom of the moving track 1, and a clamping mechanism 3 at the bottom of the adjustment mechanism 2. The adjustment mechanism 2 includes a vertical box 21 fixedly connected to the bottom of the moving track 1, an extension component 22 disposed inside the vertical box 21, a rotating component 23 disposed at the bottom of the vertical box 21, and an inclined component 24 disposed at the bottom of the rotating component 23. The clamping mechanism 3 includes a fixing plate 31 disposed at the bottom of the inclined component 24, a positioning plate 32 fixedly connected to one side of the bottom of the fixing plate 31, and a clamping component 33 disposed on one side of the fixing plate 31.

[0025] As a preferred embodiment of the above: the adjustment mechanism 2 is responsible for completing the lifting, rotation, and pitching actions. When the extension component 22 is activated, the first hydraulic cylinder 221 pushes the push plate 222 downward, causing the magnetic suction rod 223 and the limit rod 225 to extend out of the vertical box 21, thereby lowering the entire lower mechanism. After the descent is completed, the electromagnet 224 is energized to magnetically attract and fix the magnetic suction rod 223 to prevent shaking. Subsequently, the rotation component 23 works, the motor 232 starts to drive the rotation plate 233 to rotate, and the support wheel 5 at the bottom of the rotation plate 233 rolls along the circular groove 4 in the connecting plate 231 to provide stable support and realize the horizontal rotation of the frame. Finally, the tilting component 24 is activated, the second hydraulic cylinder 242 extends and retracts, and through the hinge with the connecting rod 241 The mechanism 3 engages with the fixed plate 31, which rotates around the hinge point to adjust the tilt angle of the frame and align it with the mounting interface. The clamping mechanism 3 grips and secures the lightweight aluminum frame. The movement of the equipment causes the positioning plate 32 to contact one side of the frame, completing the initial lateral positioning. Then, the adjusting mechanism 2 drives the fixed plate 31 to move downward, so that the bottom top contact plate 331 contacts the top of the frame. Finally, the clamping assembly 33 begins to work. The third hydraulic cylinder 332 retracts, pulling the clamping plate 333 upward. At the same time, the airbag 334 on the clamping plate 333 inflates, making it fit tightly against the bottom of the frame. Together with the top contact plate 331, it forms a stable clamping force that wraps around the frame from both the top and bottom, firmly fixing the frame in place.

[0026] Example 2 Please see Figures 1-5Based on Embodiment 1, the extension component 22 includes a first hydraulic cylinder 221 fixedly connected inside the vertical box 21, a push plate 222 fixedly connected to the output end of the first hydraulic cylinder 221, a magnetic suction rod 223 fixedly connected to the bottom of the push plate 222, an electromagnet 224 fixedly connected to the bottom of the vertical box 21, and a limiting rod 225 fixedly connected to the bottom of the push plate 222. The electromagnet 224 has a sliding through hole adapted to the magnetic suction rod 223, and the vertical box 21 has a limiting through hole adapted to the limiting rod 225. The rotating component 23 includes a connecting plate 231 disposed at the bottom of the vertical box 21. The top of the connecting plate 231 is fixedly connected to the bottom of the magnetic suction rod 223 and the limiting rod 225. A motor 232 is fixedly connected to the top of the connecting plate 231, and a rotating plate 233 is fixedly connected to the output end of the motor 232. A circular groove 4 is formed inside the connecting plate 231, and a support wheel 5 is slidably connected inside the circular groove 4. The bottom of the support wheel 5 is fixedly connected to the top of the rotating plate 233. A handle is fixedly connected to one side of the connecting plate 231. The tilting assembly 24 includes a connecting rod 241 located on one side of the bottom of the vertical box 21, and a second hydraulic cylinder 242 located on one side of the bottom of the vertical box 21. The top of the connecting rod 241 is fixedly connected to the bottom of the rotating plate 233, and the bottom of the connecting rod 241 is movably connected to the top of the fixed plate 31 via a rotating shaft. The top of the second hydraulic cylinder 242 is movably connected to the bottom of the rotating plate 233 via a rotating shaft, and the output end of the second hydraulic cylinder 242 is movably connected to the top of the fixed plate 31 via a rotating shaft. The clamping assembly 33 includes a top contact plate 331 fixedly connected to the bottom of the fixed plate 31, a third hydraulic cylinder 332 fixedly connected to the top of the fixed plate 31, a clamping plate 333 fixedly connected to the output end of the third hydraulic cylinder 332, and an airbag 334 fixedly connected to one side of the clamping plate 333. There are three airbags 334, and the three airbags 334 are designed in a triangular shape.

[0027] As a preferred embodiment of the above: the extension component 22 is used to extend or pull up the clamping mechanism 3; the rotation component 23, after clamping the frame, drives the rotating plate 233 to rotate to adjust the orientation of the frame; the circular groove 4 and the support wheel 5 support the rotating plate 233 so that the rotating plate 233 can bear a certain weight; the tilting component 24, after adjusting the rotation direction of the frame, allows the extension and retraction of the second hydraulic cylinder 242 to adjust the clamping mechanism. The tilt angle of the holding mechanism 3 aligns the frame with the installation position. Through the setting of the clamping component 33, one side of the positioning plate 32 contacts one side of the frame to complete the side positioning. At this time, the extension component 22 moves down the fixing plate 31 so that the top contact plate 331 at the bottom of the fixing plate 31 contacts the top of the frame. Finally, the airbag 334 inflates, and at the same time the third hydraulic cylinder 332 contracts. The inflated airbag 334, driven by the clamping plate 333, contacts the bottom of the frame and, together with the top contact plate 331, clamps and fixes the frame.

[0028] The working principle of this utility model is as follows: When the equipment starts working, the operator pushes the adjustment mechanism 2 and the clamping mechanism 3 to the frame position by pushing the handle. The first hydraulic cylinder 221 pushes the push plate 222 and the magnetic suction rod 223 and the limit rod 225 connected to it to extend downward from the vertical box 21, realizing the vertical descent of the entire clamping mechanism 3, so that the positioning plate 32 on one side of the fixed plate 31 contacts the side of the frame and completes the initial positioning. Then the extension component 22 drives the fixed plate 31 to move down, so that the bottom top contact plate 331 contacts the top of the frame. After it is in place, the electromagnet 224 is energized to attract the magnetic suction rod 223 and lock the current height. Then the third hydraulic cylinder 332 retracts and pulls the clamping plate 333 to move upward. At the same time, the air bag 334 on the clamping plate 333 inflates and expands, tightly adhering to the frame from the bottom, and working together with the top contact plate 331 to firmly fix the frame.

[0029] After clamping is completed, the adjustment mechanism 2 begins to adjust the frame's position and orientation in multiple degrees of freedom. First, the first hydraulic cylinder 221 of the extension component 22 drives the entire lower mechanism to rise and fall through the push plate 222. When needed, the electromagnet 224 is energized to attract the magnetic rod 223 to lock the height. Then, the motor 232 of the rotation component 23 drives the rotating plate 233 to rotate. The horizontal rotation of the frame is achieved by the rolling of the support wheel 5 in the circular groove 4. Finally, the second hydraulic cylinder 242 of the tilting component 24 extends and retracts. Through linkage with the connecting rod 241, the fixing plate 31 rotates around the hinge point to adjust the pitch angle of the frame until the frame is aligned with the installation position, completing the final positioning for installation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
