Abstract

The invention discloses an integrated welding-die mechanism for rear frames of small-sized wheel loaders and medium-sized wheel loaders. The integrated welding-die mechanism for the rear frames of the small-sized wheel loaders and the medium-sized wheel loaders comprises a welding-die base, wherein a hinged plate support, a pair of front fixing plates, a pair of gearbox installing locating plates, a pair of front engine installing hole fixing plates, a pair of rear engine installing hole fixing plates, two front-and-back swing frame hole blocks, a front-and-back swing frame hole locating pin roll, a gear pump installing base limiting plate, a pair of left-and-right longitudinal beam locating bases and a pair of rear tail plate limiting blocks are arranged on the welding-die base in sequence, the front-and-back swing frame hole locating pin roll is arranged between the front-and-back swing frame hole blocks, two vertically-arranged middle limiting plates are arranged on the hinged plate support, and a hinged plate hole locating core rod is arranged on the two middle limiting plates. The integrated welding-die mechanism for the rear frames of the small-sized wheel loaders and the medium-sized wheel loaders can ensure accuracy of assembled and welded assemblies, prevent welding deformation, meet requirement for mass production of the loaders, greatly improve efficiency of assembly, and ensure strength of welding, and meanwhile stress deformation of components cannot happen after the components are welded.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to an integrated mold welding mechanism for the rear frame of a small and medium-sized wheel loader. Background technique [0002] Loader is a kind of mobile and flexible engineering machinery, which is widely used in various factories, mines and engineering construction sites. The use of loaders can improve efficiency and avoid waste of manpower and material resources. The rear frame of the loader is a space structure with a relatively complex structure welded by steel plates. The rear frame is mainly composed of four parts: rear hinged frame, side plate, sub-frame support frame and rear frame. The rear frame of this loader is simple in shape, and the whole structure is welded by steel plates with simple shapes, so it is easy to manufacture, and this space box-shaped rear frame is used for the engine, gearbox, cab, console, The fuel tank, oil tank, and counterweights provide a ...
