Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically to a rotating and lifting tooling for a new energy vehicle battery tray. Background Technology

[0002] In the process of realizing this utility model, the inventors discovered that:

[0003] New energy battery trays (such as aluminum alloy frames) need to be rotated horizontally frequently during cleaning, grinding, and testing processes. Due to the heavy weight and large size of the products, traditional manual rotation and sliding is inefficient and poses safety hazards. Moreover, there is a significant height difference between the normal operating height and the transmission height on the production line, requiring manual handling, which is labor-intensive and prone to collisions and slippage, resulting in poor appearance quality. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, this utility model proposes a rotating lifting fixture for a new energy vehicle battery tray, which can improve efficiency and enhance the appearance quality of the product.

[0005] Therefore, the technical solution of this utility model is as follows: a rotating lifting fixture for a new energy vehicle battery tray, comprising a workbench arranged on an assembly line, characterized in that: a slewing bearing is fixed in the middle of the top of the workbench, a rotating platform is fixed on the slewing bearing, pads are respectively provided at the four corners and the middle of the rotating platform, and through clearance grooves are respectively opened at the front and rear along the assembly line direction of the rotating platform.

[0006] A vertical plate is fixed below the workbench. Vertical slide rails are spaced apart on one side of the vertical plate. Sliders are engaged with the slide rails. Inverted L-shaped mounting seats are fixed on the sliders. The tops of the two L-shaped mounting seats are connected as one unit by a connecting plate. A cylinder is fixed on the vertical plate below the connecting plate. The piston rod of the cylinder is fixedly connected to the bottom of the connecting plate. A U-shaped lifting bracket with an upward opening is fixed on the top of the connecting plate. The two columns of the U-shaped lifting bracket pass through the open cavity on the workbench. The top of the columns is fixed with U-shaped sliding rails that are adapted to the clearance groove. Rollers are spaced apart in the U-shaped groove.

[0007] Preferably, the worktable and the slewing bearing are each provided with a downward-facing U-shaped seat on both sides along the production line direction. The top of the U-shaped seat is provided with multiple spring-loaded positioning plungers, and the bottom of the rotating platform is provided with corresponding plunger grooves. This arrangement aims to position the rotating platform before lifting the U-shaped lifting bracket, preventing interference when the pulley arm rises and passes through the clearance groove.

[0008] Preferably, a manual control valve is also provided on one side of the workbench, which is connected to the cylinder via a pipeline; hydraulic buffers are respectively provided on the vertical plate and the U-shaped lifting bracket. When the U-shaped lifting bracket is in its lowest position, the hydraulic buffer on the vertical plate abuts against the bottom of the connecting plate; when the U-shaped lifting bracket rises to its highest position, the hydraulic buffer on the U-shaped lifting bracket abuts against the bottom surface of the workbench. The purpose is to provide a buffering effect and reduce the impact force during lifting.

[0009] Preferably, the pad is made of polyurethane, and the surface of the roller is covered with a polyurethane adhesive layer. This provides both load-bearing and anti-slip functions while preventing scratches on the pallet surface.

[0010] Preferably, the four corners of the rotating platform are rounded to prevent bumps and knocks when rotating the platform.

[0011] Preferably, the workbench has four corners fixed with legs by mounting blocks, and a height-adjustable support is provided on one side of each leg. The height-adjustable support has an L-shaped structure, with two vertically spaced oblong holes on the vertical section of the L-shaped structure. Bolts are slidably connected in the oblong holes. The mounting block has threaded holes, and the height-adjustable support is fixed to the end face of the mounting block by bolts. This allows for convenient adjustment of the workbench height as needed.

[0012] Beneficial effects: This utility model has a compact structure, integrating rotation, lifting, and sliding functions. It achieves rapid lifting and lowering through pneumatic drive and can adapt to battery trays of different sizes. This utility model can significantly improve production efficiency, part appearance quality, and ease of installation and use, while greatly reducing labor intensity. Attached Figure Description

A slewing bearing 2 is fixed in the center of the top of the workbench surface. A rotating platform 3 is fixed on the slewing bearing. Pads 4 are provided at the four corners and the center of the rotating platform. Through clearance grooves 5 are provided at the front and rear of the rotating platform along the assembly line direction.

[0022] A vertical plate 6 is fixed below the workbench 1. Vertical slide rails 7 are spaced apart on one side of the vertical plate. Slider 8 is snapped onto the slide rail. An inverted L-shaped mounting seat 9 is fixed on the slider. Vertical reinforcing ribs 91 are provided on the vertical and horizontal sections of the L-shaped mounting seat. The tops of the two L-shaped mounting seats are connected as one unit by a connecting plate 10. A cylinder 11 is fixed on the vertical plate below the connecting plate. The piston rod of the cylinder is fixedly connected to the bottom of the connecting plate. A U-shaped lifting bracket 12 with an upward opening is fixed on the top of the connecting plate. The two columns of the U-shaped lifting bracket pass through the open cavity P on the workbench surface. The top of the columns is fixed with U-shaped sliding rails 13 that are adapted to the clearance groove. Rollers 14 are spaced apart in the U-shaped groove.

[0023] In this embodiment, the worktable and the slewing bearing are respectively provided with U-shaped seats 15 with downward openings on both sides along the production line direction. The top of the U-shaped seats is provided with multiple spring positioning plungers 16, and the bottom of the rotating platform is provided with corresponding plunger grooves.

[0024] In this technical solution, the purpose of this setting is to position the rotating platform before lifting the U-shaped lifting bracket, thereby avoiding interference when the pulley arm rises and passes through the clearance groove.

[0026] In this technical solution, when the U-shaped lifting frame is at its lowest position, the hydraulic buffer on the vertical plate abuts against the bottom of the connecting plate. When the U-shaped lifting frame rises to its highest position, the hydraulic buffer on the U-shaped lifting bracket abuts against the bottom surface of the worktable. The purpose is to buffer the impact force during lifting.

[0027] Preferably, the pad 4 is made of polyurethane material, and the surface of the roller is covered with a polyurethane adhesive layer;

[0028] In this technical solution, protective materials are used, which have both load-bearing and anti-slip functions, while avoiding scratches on the pallet surface.

[0029] In this embodiment, the four corners of the rotating platform 3 adopt an arc transition;

[0030] In this technical solution, the use of an arc-shaped transition can avoid collisions and personal injury when rotating the platform.

[0034] The working principle of this utility model:

[0035] In use, first rotate the rotating platform until it is limited by the spring positioning plunger, then open the cylinder to raise the U-shaped lifting frame to the production line height position, push the battery tray from the previous process onto the U-shaped sliding track, and then lower the U-shaped lifting frame using the cylinder. The battery tray will fall onto the pad on the rotating platform. At this time, the rotating platform can be rotated to perform this process. After the operation is completed, return the rotating platform to the state where the spring positioning plunger 16 is engaged with the plunger groove for positioning, then lift the U-shaped lifting frame using the cylinder, and move the U-shaped sliding track up to lift the battery tray to the production line height position. Push the battery tray to the next process on the production line. Once this process is completed, repeat the above operation.

[0036] Any aspects not described in detail in this specification are techniques well-known in the art.
