Problems solved by technology

In recent years, with the improvement of the quality of the whole vehicle, the requirements for the accuracy of the sub-frame have become higher and higher, and the parts will be deformed due to heat concentration during the welding process, and the sliding cylinder of the fixture will form a certain tensile rebound. Affect the repeatability and stability of the welding fixture, and at the same time reduce the life of the positioning pins used in the sliding structure

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Such as Figure 1-8 As shown, a sub-frame positioning and assembling tooling includes a workbench 1. The overall shape of the workbench 1 is a square frame, and the left and right sides of the workbench 1 are respectively provided with a fixed assembly position 2 and a first positioning component 3, wherein each The fixed assembly positions 2 are respectively used for loading the left and right longitudinal beams 83 , 84 , and each first positioning component 3 corresponds to each fixed assembly position 2 one by one and is used for positioning the longitudinal beams on each fixed assembly position 2 respectively. At the same time, the front and rear sides of the above-mentioned workbench 1 are respectively provided with movable assembly positions 4, second positioning components 5, slide-in structures 6 and self-locking structures 7, w...

Abstract

The invention relates to an auxiliary frame positioning and assembling tool which comprises a fixed assembling position, a first positioning assembly, a movable assembling position, a second positioning assembly, a slide-in structure and a self-locking structure, wherein each slide-in cylinder can drive a corresponding slide-in platform in order that each cross beam slides to a splicing position of a corresponding longitudinal beam; and the self-locking structure is used for locking the corresponding slide-in platform and a workbench. Compared with the prior art, the auxiliary frame positioning and assembling tool can stably load and position each cross beam and each longitudinal beam of the auxiliary frame, facilitates the assembly of each cross beam and the corresponding longitudinal beam through the slide-in structure, and locks the corresponding slide-in platform and the workbench through the self-locking structure, so as to avoid the influence of tension springback generated by welding heat on the slide-in cylinders, avoid the influence of deformation on parts due to heat concentration in the welding process. The auxiliary frame positioning and assembling tool is improved in repeatability precision and stability, and has a long service life.

Description

technical field [0001] The invention relates to the field of processing automobile chassis parts, in particular to a positioning assembly tool for a sub-frame. Background technique [0002] The sub-frame is the skeleton of the front and rear axles and an important part of the car chassis. Its main function is to reduce the impact of road vibration on the car body, improve the connection stiffness of the suspension system, and improve the comfort and stability of the car during driving. , In addition, the sub-frame can also reduce the noise caused by the engine and road vibration, and improve the mute level in the car cabin. [0003] With the continuous development and progress of welding technology, modern welding technology has been more and more widely used in the mechanical equipment manufacturing industry. Welding fixtures can not only ensure the manufacturing accuracy of products, but also improve labor productivity and effectively reduce workers. labor intensity. In ...
