Embodiment Construction

[0030] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0031] The present invention firstly discloses a positioning tire for large-scale frame welding. The positioning tire for welding is a combined tire, which includes a basic welding tire I1 and a positioning detection tire II2. The basic welding tire I1 is used to assemble the longitudinal beam 31, the beam 32, The swing arm support part 37 and the cross brace part 38 have the functions of positioning detection tire II2; 1) visually inspect whether the accuracy of the key parts of the main body of the frame assembled by the basic welding tire I1 meets the requirements, and use the position detection tire II2 to correct the unqualified welding. 2) further assemble and weld components such as the rear outrigger 34, the front outrigger 35 and the front section 36 of the vehicle frame on the main body of the vehicle frame to complete the vehicl...

Abstract

The invention relates to a large car frame welding location tyre and a large car frame welding technological method. The location tyre comprises a basic welding tyre I and a location and detection tyre II; the basic welding tyre I comprises a base I and a location bracket I; the location bracket I is located on the base I; a longitudinal beam location assembly is arranged on the location bracket I; the longitudinal beam location assembly comprises a longitudinal beam front location plate which is arranged at the end of the location bracket I, and further comprises a longitudinal beam side location plate which is obliquely arranged; a transverse beam location assembly is further arranged on the location bracket I; the transverse beam location assembly comprises a transverse beam shaft location component and a transverse beam longitudinal location component; and the transverse beam shaft location component is a supporting shaft seat which is in fit with a movable connecting shaft. Combined welding of a large car frame is completed with the adoption of a mode that two location tyres are combined, and the large car frame welding location tyre and the large car frame welding technological method have the advantages of high location accuracy and high welding speed; and welding work is completed in a tyre mould, so that welding deformation is reduced effectively, and the welding accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of large-scale vehicle frame welding, in particular to a positioning tire for large-scale vehicle frame welding, and also relates to a process method for using the positioning tire to complete vehicle frame welding. Background technique [0002] Each assembly of the car is directly or indirectly installed on the frame. The frame is the basic part that bears the load. The load includes the static load of the car and the dynamic load during driving. Therefore, the frame is one of the key components that affect the service life of the car. . [0003] At present, domestic trucks adopt side beam welded frame, that is, the frame is welded into a closed frame by two grooved longitudinal beams and several cross beams. In this welding, due to the large number of joints, the welding is difficult, and the welding strength and welding accuracy of the weld seam are difficult to guarantee. Therefore, how to design a rea...
