Tool for assembling and welding telescopic arm forklift frame

Abstract

The invention discloses a tool for assembling and welding a telescopic arm forklift frame. The tool comprises a welding platform, wherein a supporting plate assembly is arranged on the welding platform; the supporting plate assembly comprises a vertical plate and two inner clamping plates which are symmetrically arranged and are used for clamping the forklift frame; the two inner clamping plates are fixedly connected to the vertical plate and are vertical to the vertical plate; a main positioning hole and a second positioning hole are formed in each inner clamping plate; a main hinge point tool shaft is arranged in each main positioning hole in a penetrating manner; a variable amplitude tool shaft is arranged in each second positioning hole in the penetrating manner; an outer clamping plate is arranged on the outer side of one inner clamping plate; an auxiliary positioning hole and a third positioning hole are formed in the outer clamping plate; the auxiliary positioning hole and the main positioning hole are coaxially arranged; the size of the auxiliary positioning hole is the same as that of the main positioning hole; and a follow-up tool shaft is arranged in the third positioning hole in the penetrating manner. The tool can be applied to assembling and welding production of the telescopic arm forklift frame 12, the concentricity of corresponding shaft sleeve holes and the position size precision of hole center distance of the telescopic arm forklift frame can be guaranteed, and the production and machining difficulty is reduced.

Description

technical field [0001] The invention relates to the processing field of telescopic arm forklifts, in particular to a tooling for assembly and welding of telescopic arm forklifts. Background technique [0002] Telescopic forklifts are also called telescopic forklifts. Because they organically combine the functions of truck cranes and traditional forklifts, the products are more flexible and adaptable. The telehandler generally supports the entire car body by the frame. When the frame of the existing telehandler is manufactured, in order to reduce the production cost and reduce the difficulty of cutting, the frame is supported by two parallel rows along the length direction. The plate and the front and rear mounting seats are integrally welded. After the overall welding of the frame is completed, the bushing hole is machined again. Due to the requirements of the concentricity and hole center distance of the bushing hole of the main hinge point of the forklift truck frame, the...
