Embodiment Construction

[0044] Before describing the preferred embodiments of the present invention, it should be noted that in the following, some orientation words used for the convenience of description, such as "left", "right", "front", "rear", etc., all have the meaning According to the orientation usually indicated after the car is assembled, for example, in figure 1 When the frame assembly 1 is assembled into a car, part A and part C in the figure are on the left side of the car, while part B and part D in the figure are on the right side of the car; part A and part B It is at the front of the car, while part C and part D are at the rear of the car. The positional relationship between other corresponding parts can be deduced by analogy. In addition, the “lower arm of the frame” referred to in the present invention is a component of the automobile suspension system, and the “under” means that it is installed under the frame.

Abstract

The invention discloses a method for producing an automotive frame assembly, which comprises the following steps: forming each component of the automotive frame assembly (1), and forming preset holes on predetermined components; welding each component of the automotive frame assembly (1) into the automotive frame assembly (1) on a welding clamp; and forming mounting holes at the positions of the preset holes on the predetermined components. Due to the technical scheme of welding first and then forming the mounting holes, smaller preset holes are punched at the key mounting holes with higher requirement on precision on the frame, and the step of forming the mounting holes is performed on the preset hole after the welding of the whole frame is finished. Therefore, the influence on the precision of the mounting holes due to welding deformation is avoided, the dimension precision of a mounting hole of a lower arm of the frame, a mounting hole of a shaft pin of a leaf spring and the like is improved, and the assembly quality of a chassis is guaranteed.

Description

Technical field [0001] The invention relates to a production method of an automobile frame assembly, in particular, to a production method of an automobile frame assembly including a step of forming mounting holes on a frame production line. Background technique [0002] The automobile frame assembly generally includes a longitudinal beam, a cross beam, and multiple mounting brackets. The frame assembly is used as a carrier for installing automobile chassis components, and has a plurality of corresponding mounting brackets, for example, for installing the lower swing arm of the frame (the lower swing arm is a component of the automobile suspension system, and is referred to below for convenience of description It is the lower swing arm mounting bracket of the "frame lower swing arm") and the leaf spring mounting bracket used to install automobile leaf springs (ie leaf springs). These mounting brackets are formed with corresponding mounting holes (see Figure 1 to Figure 5 ), to i...
