Technical Field

[0001] The utility model relates to an electric turning tool used in the welding process of loader parts, belonging to the loader technology and mechanical welding processing technology field. Background Art

[0002] Welding is an important process in the production and manufacturing of mechanical components. The strength of the welds between parts is crucial to ensure product quality, performance, life, and even the safety of national and personal life and property. However, due to the design and construction of the structure and the three-dimensional and all-round position of the weld, in order to ensure the welding quality, fusion depth, and weld foot size, the structural workpiece needs to be turned over during the welding process to cooperate with the operation of the welding gun for all-round welding. When the weight is greater than or equal to 1000kg, turning it over manually or using a crane or a hoist cannot meet the requirements in terms of labor intensity, site safety, and efficiency. In addition, there are problems with orientation and angle differences, which cannot meet production needs. After on-site investigation and discussion, a universal seat frame and a special positioning panel for workpieces were developed.

[0003] The technical problems existing in the welding of the existing frame side boxes are:

[0004] 1. The welding process of the weld seams in all directions of the workpiece is turned over, making it difficult to ensure the welding positions and weld leg sizes of all weld seams;

[0005] 2. The existing manual lifting and flipping by hooking position are inefficient and cannot guarantee the welding position;

[0006] 3. The current flip welding method has quality and safety risks;

[0007] 4. It is impossible to ensure the penetration depth and strength of all welds, thereby ensuring the quality of the workpiece and even the entire machine;

[0008] 5. Low efficiency and high labor intensity for operators. Summary of the invention

[0009] The technical problem to be solved by the utility model is to provide a set of electric turning tooling suitable for welding of this type of components, while having the versatility of being extended and promoted to welding of various types of components.

[0010] In order to solve the above technical problems, the utility model provides an electric flipping tooling for a frame side box, which includes a flipping base plate for fixing the frame side box, and a spindle hole positioning column and a locking device are provided on the flipping base plate; a driving shaft component and a driven shaft component are respectively provided on both sides of the flipping base plate.

[0011] Preferably, the active shaft component is connected to the electric hydraulic drum brake through a coupling, the electric hydraulic drum brake is connected to the helical gear hardened surface reducer, the helical gear hardened surface reducer is arranged on the active support, and the helical gear hardened surface reducer is controlled by the electric control cabinet.

[0012] More preferably, the driven shaft component is arranged on the driven end support through a bearing seat.

[0013] Furthermore, the active support and the driven end support are fixed on the base by welding.

[0014] Preferably, the flip bottom plate is also provided with a side positioning device.

[0015] More preferably, the side positioning device is connected to the flip bottom plate via a detachable structure.

[0016] Preferably, the locking device is a snap-fit ​​structure, which can be applied to clamping and locking workpieces of various shapes and sizes, thus ensuring its applicability.

[0017] The flip bottom plate can be disassembled and replaced according to the actual workpiece type and outer contour size, and can be set as a special bottom plate for each component.

[0018] The utility model has low manufacturing difficulty, common materials, simple operation, strong applicability and promotion space, and has obvious benefits in ensuring product quality, improving production efficiency, reducing the labor intensity of post personnel, and improving on-site safety.

[0019] Practice has proved that the use of the utility model has obvious advantages over the previous flipping using crane lifting and unfixed fulcrums: accurate flipping positioning ensures quality, controllable spatial area ensures safety, electric flipping improves efficiency and reduces labor intensity, and has higher safety. This tooling can realize the clamping and welding of the frame side boxes of all product models, and other parts can be flipped by replacing the appropriate flip bottom plate, and the main components are universal.
