Description

Technical Field

[0001] The utility model relates to an assembly tool for a rotating arm column component, belonging to the field of aerial work vehicles. Background Art

[0002] As aerial work vehicles are used more and more widely in different fields, customers have wider and wider requirements for the operating range of aerial work vehicles. Aerial work vehicles with a slewing arm column assembly 6 have come into being. The slewing arm column assembly 6 usually includes a slewing arm column 61, a slewing arm 62, a bucket swing bracket 63, a lifting bracket 64, etc. The existing arm assembly process can no longer meet the production needs. The arm assembly process in the existing technology is to assemble the slewing arm column 61, the slewing arm 62, the bucket swing bracket 63, and the lifting bracket 64 on the arm in sequence to meet the needs of existing production.

[0003] We found that the existing assembly process has several shortcomings. First, the arm assembly station has a long operation time, which becomes a bottleneck process in the assembly line production; second, the operators are relatively concentrated, and there will be interference with each other's operations during assembly; third, there is a possibility of the arm overturning when the rotating arm 62 and the bucket swing bracket 63 are assembled at the arm head. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a tool for assembling a rotating arm column assembly with a reasonable structural design.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: the structural feature of the tooling for assembling the rotating arm column assembly is that it includes a wall panel assembly, a bracket, a base frame, wheels, and a core rod for fixing the rotating arm column assembly to the wall panel assembly, the wall panel assembly is arranged on the bracket, the bracket is arranged on the top of the base frame, the wheels are arranged at the bottom of the base frame, and the core rod cooperates with the wall panel assembly.

[0006] Furthermore, the wall panel assembly includes a wall panel, a bottom plate and a core rod hole, the core rod hole is arranged on the wall panel, the wall panel is arranged on the bottom plate, and the bottom plate is arranged on the bracket.

[0007] Furthermore, there are two wall panels, which are symmetrically arranged, and a space for placing the rotating arm column assembly is formed between the two wall panels.

[0008] Furthermore, there are two core rod holes, and the two core rod holes are used to pass the core rod.

[0009] Furthermore, there are four wheels, two of which are fixed wheels and the other two are universal wheels with brakes.

[0010] Compared with the prior art, the utility model has the following advantages: when the swing arm column assembly is assembled by the swing arm column assembly assembly tool, the swing arm column is first fixed to the wall panel through the core rod, and then the assembly operation of the swing arm, bucket swing bracket, lifting bracket and other parts is continued to form a swing arm column assembly; the original assembly sequence is changed, and there is no need to install the swing arm column, swing arm, bucket swing bracket, lifting bracket and other parts on the boom in sequence after the boom is assembled. Instead, a modular assembly method is adopted, that is, the pre-assembled swing arm column assembly is directly installed on the boom; the phenomenon of long assembly time is avoided, and the working efficiency is improved. At the same time, the assembly tool can be removed when not in use, saving working space. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The assembly tool for the rotating arm column assembly in this embodiment includes a wall panel assembly 1, a bracket 2, a base frame 3, wheels 4, and a core rod 5 for fixing the rotating arm column assembly 6 on the wall panel assembly 1. The core rod 5 cooperates with the wall panel assembly 1. The wall panel assembly 1 is set on the bracket 2, the bracket 2 is set on the top of the base frame 3, and the wheels 4 are set at the bottom of the base frame 3. There are four wheels 4, two of which are fixed wheels and the other two are universal wheels with brakes.

[0026] In this embodiment, the wall panel assembly 1 includes a wall panel 11 , a bottom plate 12 and a core rod hole 13 . The core rod hole 13 is provided on the wall panel 11 . The wall panel 11 is provided on the bottom plate 12 . The bottom plate 12 is provided on the bracket 2 .

[0028] Specifically, the boom column 61 is the base for the aerial work vehicle bucket rotation axis and the boom 62, bucket swing bracket 63, and lifting bracket. Due to its special structure, ordinary workbenches cannot perform clamping operations on such irregular parts. When the boom column assembly tool is in use, after stepping on the braked wheel 4 under the chassis 3, the boom column 61 is installed into the space between the two matching wall panels 11, and the core rod 5 is simply passed through the boom column 61 to easily fix the boom column 61 in mid-air on this assembly tool to prevent the boom column 61 from axial stringing and radial rotation. The boom 62, bucket swing bracket 63, lifting bracket 64 and other components and the oil circuit layout are continued on this assembly tool, thereby changing the existing assembly process and realizing the simultaneous assembly of the working arm assembly and the boom column assembly 6.

[0029] This assembly tool for the swing arm column assembly can also provide stable support for it. There will be no shaking during the assembly process. The fixation is reliable and firm, which changes the process of boom assembly and lays a good foundation for further refining the boom assembly process, thereby improving the assembly efficiency of the boom assembly. The use of the assembly tool for the swing arm column assembly not only brings convenience to the addition of a swing arm assembly station, but also improves the assembly efficiency of the entire vehicle.

[0030] That is to say, the arm column 61, the arm 62, the bucket swing bracket 63, the lifting bracket 64, etc. can be pre-assembled into the arm column assembly 6 on the arm column assembly tool, and then the arm column assembly 6 can be installed on the arm frame to achieve modular assembly.

[0031] This assembly tool is used for aerial work vehicles with rotating arms, and can also be used for the assembly of rotating arms of other similar structures. This assembly tool is safe and reliable, simple in structure, low in cost, saves manpower, and is suitable for assembly line production. It has higher processability and economy for the use of the same series of products with standardized design.
