Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically to a car parts transport rack. Background Technology

[0002] Automotive parts transport racks are key equipment in the automotive supply chain to ensure the flow of parts. Their role is to achieve safety and efficiency in the entire process of parts transportation, storage, loading and unloading through specialized design.

[0003] In the prior art, a car parts transport rack with publication number "CN218558930U" relates to the field of automotive production technology. The car parts transport rack includes a support frame, on which a lead screw is vertically rotatably connected. The lead screw includes multiple threaded sections and multiple smooth sections. A first placement layer and multiple second placement layers are provided on the lead screw. The first placement layer is threadedly engaged with the uppermost threaded section of the lead screw. Each second placement layer is located within a smooth section and can be threadedly engaged with any of the threaded sections. The thickness of the first placement layer is greater than the thickness of any of the second placement layers, and the length of any smooth section is consistent with the thickness of the corresponding second placement layer. This application facilitates the handling and storage of parts by operators without the need for additional auxiliary tools such as ladders, thus eliminating the need for climbing and avoiding significant time and effort wasted by operators.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Existing transport racks are mostly fixed-angle support structures, which cannot be dynamically adjusted to accommodate the different center of gravity positions of various components. For irregularly shaped parts with a shifted center of gravity, traditional racks can only provide horizontal or fixed-angle support, causing the parts to sway during transport due to the mismatch between the center of gravity and the support points. This swaying can easily lead to collisions between the parts and the rack or other objects, especially during long-distance transport or on bumpy roads, potentially causing surface damage, structural deformation, or even functional failure, increasing the defect rate and repair costs. Utility Model Content

[0006] The purpose of this invention is to provide an automotive parts transport rack to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automotive parts transport rack includes a fixed frame and a movable frame. The movable frame is movably mounted on the fixed frame, and the side of the movable frame is L-shaped. A plurality of slide rails are fixedly mounted on the fixed frame, and sliders are slidably mounted on the slide rails. The nodal positions of the movable frame are rotatably mounted on the sliders.

[0009] The fixed frame is provided with a number of first support rods. The first support rods and the slider together support the movable frame, and the height of the first support rods is higher than the height of the slider. By changing the position of the slider on the slide rail, the tilt angle of the movable frame can be changed.

[0010] It also includes a synchronization adjustment component for adjusting and fixing the slider.

[0011] Preferably, the synchronous adjustment assembly includes a plurality of screws rotatably mounted on a fixed frame, each screw being fitted with a nut that matches the screw, and the nut being fixedly connected to a slider. When the screws rotate, the nut drives the slider to move on the slide rail.

[0012] It also includes a rotating rod rotatably mounted on a fixed frame, on which several worm gears are fixedly mounted, and on which several screws are fixedly mounted worm wheels. The worm wheels mesh with the worm gears for transmission. When the rotating rod rotates, it drives the several screws to rotate through the worm gears and worm wheels, thereby adjusting the position of the slider. The worm gears, worm wheels and screws lock the position of the slider through a self-locking action to fix the tilt angle of the movable frame.

[0013] Preferably, a first pulley is rotatably mounted on the first support rod, and the first pulley contacts the bottom surface of the movable frame.

[0014] Preferably, the movable frame is provided with guide plates, which are located on both sides of the first pulley.

[0015] Preferably, a plurality of support frames are fixedly installed on the fixed frame, and a plurality of second pulleys are installed on the support frames, the second pulleys being in contact with the side wall of the movable frame.

[0016] Preferably, the movable frame is provided with a number of third pulleys, and the fixed frame is fixedly provided with a number of tracks, wherein the third pulleys cooperate with the tracks and the number of the third pulleys matches.

[0017] Preferably, a handwheel is provided at one end of the rotating rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. When placing automotive parts (such as automotive body panels), different parts have different shapes and sizes, and their centers of gravity are also different. By changing the tilt angle of the movable frame, the center of gravity of the parts on the transport frame can be adjusted, making the center of gravity of the parts more stable and reducing the risk of parts shaking, colliding, or even falling during transportation due to an unstable center of gravity.

[0020] 2. During automobile production, various parts need to be transported. Some parts have special shapes and structures. Inclined movable frames can better conform to their shapes, providing more fitting and stable support for the parts and improving transportation safety. For example, for parts with curved surfaces, inclined movable frames allow the curved surfaces to make better contact with the frame, preventing damage to the parts during transportation due to insecure fixing.

[0021] 3. When loading and unloading parts, the tilted movable frame can position the parts at a more convenient angle for operation. For example, when it is necessary to remove parts that are located at a higher position from the transport frame, tilting the movable frame at a certain angle can bring the parts closer to the operator, reduce the difficulty of handling the parts, and improve loading and unloading efficiency.

[0022] In use, the operator rotates the handwheel at one end of the rotating rod, causing the rotating rod and the worm gear fixed thereon to rotate. The worm gear meshes with the worm wheel on the screw, causing the screw to rotate. When the screw rotates, the nut that meshes with it causes the slider to slide on the slide rail. Because the movable frame node is rotatably connected to the slider and supported by the slider and the first support rod, the movement of the slider changes the position of the support points on both sides of the movable frame, causing it to tilt. This allows for adjustment of the center of gravity of automotive parts, adapting to different parts and facilitating loading and unloading. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] The fixed frame 1 of this automotive parts transport rack is welded from high-strength steel, forming a stable rectangular frame structure. Mounting interfaces are provided on its top and sides for fixing components such as the slide rail 3 and support frame 9. The movable frame 2 is constructed from lightweight aluminum alloy profiles. The horizontal and vertical sections of the L-shaped side are fixed by riveting or welding with angle brackets, ensuring structural strength while reducing overall weight. The top surface of the horizontal section is equipped with an anti-slip rubber pad for placing automotive sheet metal parts such as body panels.

[0032] The slide rail 3 on the fixed frame 1 is horizontally fixed to the top of the frame by bolts. The slide rail 3 adopts a T-slot structure. The slider 4 is embedded in the slot and is slidably connected by the ball bearing at the bottom, ensuring that the slider 4 moves smoothly and has a certain load-bearing capacity.

[0033] The node position of the movable frame 2 is rotatably connected to the slider 4 via a pin. The pin is equipped with limit springs at both ends to prevent the movable frame 2 from separating from the slider 4, while allowing the movable frame 2 to rotate around the pin to adjust the tilt angle.

[0034] The first support rod 5 is a hollow steel pipe, vertically welded to the top of the fixed frame 1. Its height is precisely controlled by the length of the pipe. A bearing seat is installed at the top and the rotating shaft of the first pulley 7 is embedded therein, allowing the first pulley 7 to rotate freely. The first pulley 7 is made of nylon, with a smooth and wear-resistant surface, which reduces friction loss when in contact with the aluminum alloy profile on the bottom of the movable frame 2. The guide plate 8 on the bottom of the movable frame 2 is made of stainless steel plate bent into an inverted U-shape, wrapping around both sides of the first pulley 7.

[0035] The screw 601 of the synchronous adjustment component is horizontally mounted on the side of the fixed frame 1 via bearing seats at both ends. The bearing seats adopt an embedded design and are fixed with screws. The external thread of the screw 601 is precisely matched with the internal thread of the nut 602. The bottom of the nut 602 is fixedly connected to the top surface of the slider 4 by welding. The rotating rod 603 is located on one side of the fixed frame 1, and its two ends are supported by deep groove ball bearings. The worm 604 is located at both ends of the rotating rod 603, and the worm wheel 605 is fixed to the end of the screw 601 by a key connection. The module and pressure angle of the worm wheel 605 and the worm 604 are matched to form a reliable transmission pair. All exposed parts of the screw 601 and the rotating rod 603 are galvanized to prevent rust from affecting the transmission performance.

[0036] The support frame 9 is a steel structure, fixed to one side of the fixed frame 1 by bolts. A second pulley 10 is installed on the top of the support frame 9. The second pulley 10 has a rubber-coated steel core structure, which can produce a certain elastic deformation when in contact with the aluminum alloy profile of the side wall of the movable frame 2, thus supporting the movable frame 2 and buffering vibration. Several third pulleys 11 are set at the middle node of the movable frame 2. The third pulleys 11 are made of nylon. A track 12 is set on the fixed frame 1 to ensure the stability of the movable frame 2 when tilted.

[0037] The handwheel 13 is injection molded from engineering plastic with anti-slip texture on the surface and is fixed to the end of the rotating rod 603 by a key connection. All metal parts of the transport frame are powder coated to form a corrosion-resistant protective layer, while rubber and plastic parts are made of aging-resistant materials to ensure the stable performance of the transport frame during long-term use.

[0038] Through the above structural design, the various components are connected by bolts, pins, bearings, gears and other means to form an organic whole. This not only meets the requirements of strength and rigidity, but also enables flexible adjustment and reliable locking of the tilt angle of the movable frame 2. At the same time, the cooperation of components such as pulleys and guide rails reduces frictional resistance and improves the convenience of operation and the safety of parts transportation.

[0039] Working Principle: During use, the operator activates the adjustment mechanism by rotating the handwheel 13 at one end of the rotating rod 603. The rotation of the handwheel 13 drives the rotating rod 603 to rotate, and since a worm gear 604 is fixedly mounted on the rotating rod 603, the worm gear 604 rotates accordingly. The worm gear 604 meshes with the worm wheel 605 on the screw 601, thereby driving several screws 601 to rotate synchronously. When the screws 601 rotate, the nut 602 that meshes with them will move axially on the screws 601. Since the nut 602 is fixedly connected to the slider 4, the slider 4 will slide along the set direction on the slide rail 3. Because the node position of the movable frame 2 is rotatably set on the slider 4 and is supported by the first support rod 5 and the slider 4, when the position of the slider 4 changes, the positions of the support points on both sides of the movable frame 2 change, breaking the original balance and causing the movable frame 2 to tilt.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
