Description

Technical Field

[0002] Driven by the continuous upgrading of the automotive industry, demand for auto parts disassembly has expanded from traditional maintenance and repair scenarios to include vehicle repair, accident repair, and the entire life cycle, including old car dismantling, resource recycling, and vehicle scrapping. This has become a key support for the sustainable development of the industry chain. With increasing market attention to disassembly efficiency, operational safety, and resource recovery rates, disassembly equipment that combines efficiency, precision, safety, and environmental adaptability has become an industry necessity. Currently, the field of auto parts disassembly equipment is accelerating its evolution toward intelligent and integrated systems, while also placing higher demands on the equipment's modularity, adjustability, and space utilization.

[0003] In specific operation scenarios, the disassembly of automotive parts requires multi-degree-of-freedom collaborative operations, such as clamping and positioning, height adjustment, rotation angle control, and other complex actions.

DETAILED DESCRIPTION

[0037] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] like Figures 1 to 14 As shown, the preferred structure of an automobile parts disassembly platform described in the present invention.

[0039] like Figure 1 As shown, the automobile parts disassembly platform of the present invention includes a composite telescopic frame 1, a telescopic support plate 2, a synchronous lifting mechanism 3, a rotating mechanism 4 and a clamping mechanism 5.

[0040] like Figure 2As shown, the composite telescopic frame 1 is composed of a telescopic rod 11, a telescopic fence 12, an upper crossbeam 13, a fence fixing crossbeam 14 and a supporting vertical rod 15 to form a square frame; the telescopic rod 11 and the upper crossbeam 13 are located at the top of the square frame, and the telescopic rod 11 is connected to the upper crossbeam 13, and the telescopic rod 11 realizes the axial positioning of the telescopic rod 111 through a telescopic expansion sleeve 111; the telescopic fence 12 and the fence fixing crossbeam 14 are located at the bottom of the square frame, and both ends of the telescopic fence 13 are fixed on the fence fixing crossbeam 14. The telescopic fence 13 is installed parallel to the telescopic rod 11; wherein, the telescopic fence 12 has a plurality of diamond-shaped connecting rod units 121 hinged to form a telescopic network structure; the two ends of the support vertical rod 15 are respectively connected to the telescopic rod 11 and the fence fixed beam 14, and a linear guide rail assembly is provided on the inner side of the support vertical rod 15, and the linear guide rail assembly includes a sliding guide rail 151 with a limit member 153 and a sliding block 152 installed for sliding; the moving device 154 is installed at the bottom of the composite telescopic frame 1, and cooperates with the composite telescopic frame 1 to complete the lateral telescopic movement.

[0041] In one embodiment, the composite telescopic frame 1 is a square frame that can be synchronously retracted and is constructed by a top telescopic rod 11, a bottom telescopic fence 12, two upper beams 13, two fence fixing beams 14 and four supporting vertical rods 15. The telescopic rod 11 is adjusted in length to adapt to automobile parts of different sizes through a telescopic expansion sleeve 111. At the same time, the telescopic fence 12 is installed parallel to the telescopic rod 11 and is respectively located at the top and bottom of the composite telescopic frame 1. The structure in which the telescopic fence 12 is arranged parallel to the telescopic rod 11 can effectively enhance the rigidity of the frame, so that when it is subjected to a large load or is impacted by external force, it maintains overall stability and shape integrity, ensuring the safety and reliability of the work. For example, in the support or lifting operation of heavy equipment, it can withstand the weight of the equipment and the vibration during the operation, and can also achieve synchronous extension and retraction up and down. A sliding guide rail 151 is installed on the inner side of each support vertical rod 15, and a sliding block 152 is provided on the guide rail. These not only provide support and guidance for the lifting and lowering movement of the telescopic support plate 2, but also limit the position of the support plate 2 by means of the limit members 153 installed on the support vertical rod 15 at the head and end of the guide rail. That is, the limit members 153 use hexagonal nuts to prevent the support plate from exceeding the predetermined range during movement, thereby improving the stability and safety of the entire frame during operation. A moving device 154 is installed at the bottom end of the support vertical rod 15. The moving device uses a universal wheel with a brake for disassembling the platform as it moves and fixes with the telescopic frame. The structural design of the composite telescopic frame 1 gives it a strong load-bearing capacity and can withstand greater weight and pressure. Whether used as a temporary support structure or as part of a permanent structure, it can stably support various automotive parts and provide a reliable load-bearing platform. The multiple supporting vertical rods 15 and cross beams of the frame can evenly distribute the load on the entire frame, avoiding local excessive force and causing structural damage, improving the overall load-bearing performance and service life of the frame, and ensuring that it remains stable and safe during long-term use.

[0042] like Figure 3 and Figure 8 As shown, the telescopic support plate 2 includes a left support plate 20 and a right support plate 21. The left support plate 20 is slidably connected to the right support plate 21 via a dovetail guide structure. The left support plate 20 is provided with a U-shaped groove 202, which forms an axial limit with the brake rod 6. The left and right support plates 20 and 21 have coaxial circular mounting holes 201 for fixing the clamping motor 50. The rotating brake disc 44 is evenly distributed with brake holes 441 around its circumference, which form an angular positioning mechanism with the brake rod 6.

[0043] In one embodiment, the left support plate 20 is connected to the right support plate 21 via a dovetail guide structure. The dovetail guide structure can ensure that the telescopic support plate 2 moves along a predetermined route when telescopic, preventing the telescopic support plate 2 from offsetting or getting stuck during movement, thereby improving the stability and reliability of the entire frame. Coaxial circular mounting holes 201 are provided on both the left support plate 20 and the right support plate 21. The coaxial circular mounting holes 201 are used to install and fix the clamping motor 50 on the telescopic support plate 2 so that the weight of the clamping motor 50 can be evenly distributed on the telescopic support plate 2, avoiding deformation or damage of the telescopic support plate 2 due to excessive local force, improving the load-bearing capacity and service life of the telescopic support plate 2, and maintaining stability and safety even when subjected to heavy loads for a long time. The design of the coaxial circular mounting holes 201 makes the installation and removal of the clamping motor 50 very convenient. Simply align the mounting hole of the clamping motor 50 with the coaxial circular mounting hole 201 on the telescopic support plate 2 and secure with bolts or other fasteners. This significantly reduces installation and disassembly time and labor costs, improving work efficiency and making it particularly suitable for scenarios where frequent replacement of the clamping motor 50 or equipment maintenance is required. A U-shaped groove 202 is provided on the left support plate 20, which is configured to slide with the brake rod 6 to limit the range of movement of the brake rod 6. This design not only ensures that the brake rod 6 always remains on the predetermined track during operation, preventing the brake rod 6 from deflecting or becoming stuck, but also allows precise control of the range of movement of the brake rod 6 by adjusting its position within the U-shaped groove 202, thereby meeting braking requirements in different operating scenarios. For example, adjusting the range of movement of the brake rod 6 under different loads or terrain conditions can achieve a more precise braking effect. The cooperation between the U-shaped groove 202 on the left support plate 20 and the brake rod 6 not only limits the range of movement of the brake rod 6, but also allows the brake rod 6 to be limited and adjusted by adjusting its position in the U-shaped groove 202. This design allows the brake rod 6 to be flexibly adjusted according to different working requirements, thereby improving the adaptability and reliability of the braking system.

[0044] In a specific embodiment, the telescopic support plate 2 is composed of a left support plate 20 and a right support plate 21 connected by a dovetail groove guide structure 22. The dovetail groove guide structure 22 ensures that the telescopic support plate 2 moves along a predetermined path during extension and retraction, avoiding deviation or jamming. A locking component is provided within the dovetail groove guide structure 22 to lock and secure the telescopic support plate 2, preventing the telescopic support plate 2 from sliding and interfering with the disassembly of automobile parts. Both the left support plate 20 and the right support plate 21 have coaxial circular mounting holes 201 formed therein to accommodate the installation space of the clamping motor 50. The left support plate 20 has a U-shaped groove 202 formed therein, and eight brake holes 441 are evenly distributed around the circumference of the rotating brake disc 44. The U-shaped groove 202 slidably cooperates with the brake rod 6 to limit the displacement range of the brake rod 6. When the rotation reaches the target angle, the brake rod 6 is manually engaged into the corresponding U-shaped groove 202 and the brake hole 441 of the rotating brake disc 44 to achieve fixation.

The unlocking operating part is connected to the boss 121a on the telescopic fence 12 via a tension spring 17; wherein, the elastic element is a tension spring, which is always in a tensioned state, driving the latching tooth to maintain engagement with the one-way ratchet bar 141, forming a locking mechanism that only allows the telescopic fence 12 to expand in one direction.

[0055] In one specific embodiment, the fence fixing crossbeam 14 of the bottom telescopic fence 12 is provided with a sliding groove 142 with a one-way ratchet 141. A right-angled pawl is mounted at the hinge point of the diamond-shaped connecting rod unit 121. The horizontal edge of the pawl is provided with a latching tooth that engages with the ratchet, and the vertical edge also serves as an unlocking operation portion, connected to a boss 121a on the diamond-shaped connecting rod unit 121 via a tension spring 17. The elastic element 17 is always in a stretched state, driving the latching tooth to maintain engagement with the ratchet. When the telescopic fence 12 is expanded by an external force, the diamond-shaped connecting rod unit 121 drives the pawl to translate along the sliding groove 142. At this time, the latching tooth, under the tension of the elastic element 17, forms a one-way sliding fit with the ratchet, allowing the fence to expand freely. When the fence is subjected to a reverse force, the latching tooth and the tooth surface of the ratchet form a self-locking angle, preventing the fence from retracting. When the fence needs to be retracted, the operator holds the vertical edge of the pawl with his fingers and pulls it outward to disengage the teeth from the ratchet groove. At this time, the fence length can be freely adjusted.

[0056] like Figure 14 As shown, an upper limit switch 7 is provided at the top of the telescopic support plate 2, and the upper limit switch 7 limits the upward stroke of the telescopic support plate 2 by contacting the upper crossbeam 13; a lower limit switch 8 is provided at the bottom of the telescopic support plate 2, and the lower limit switch 8 limits the downward stroke of the telescopic support plate 2 by contacting the trigger rod 801.

[0057] In a specific embodiment, an upper limit switch 7 and a lower limit switch 8 are respectively installed on the top and bottom of the telescopic support plate 2. The upper limit switch 7 is triggered by the upper crossbeam 13, and the lower limit switch 8 is triggered by the trigger rod 801. When the limit switch triggers the signal, the lifting motor 30 stops and the electromagnetic brake is started to realize the control of the lifting stroke.

[0058] The operating principle of the automotive parts disassembly platform described herein is as follows: Once the operator positions the auto part to be disassembled within the working area of the telescopic support plate 2, the composite telescopic frame 1 is quickly locked to the target width via the telescopic expansion sleeve 111. The synchronous lifting mechanism 3 then drives the ball screw module 36 to raise the support plate to the working height. The electromagnetic brake and the self-locking screw provide dual protection. The clamping motor 50 then outputs high torque via the planetary reduction gear, driving the clamping blocks 55 on the four sets of clamping links 54 to perform radial clamping motion along linear guideways 561. The clamping blocks 55 are equipped with replaceable anti-slip pads 551 with anti-slip ridges to enhance workpiece stability during clamping. During this process, the rotating motor 40, via the drive gear 42, meshes with the outer ring gear of the slewing support bearing 43 to rotate the clamped part. When securing the part, the brake lever 6 engages the brake hole 441 of the rotating brake disc 44 and the U-shaped groove 202 on the telescopic support plate 2 to achieve locking. The final limit switch automatically cuts off the power and activates the electromagnetic brake at the stroke limit position, forming a closed-loop safety operation process.
