Steel structure system for precisely positioning side wall total assembly frames

Abstract

The invention relates to a steel structure system for precisely positioning side wall total assembly frames. The steel structure system is applied to a white automobile body welding production line and comprises bottom plate frame units, guide rail units, guiding and supporting units and positioning and clamping stand column units, wherein the bottom plate frame units are arranged at the bottom and are used for supporting and mounting function units; the guide rail units are arranged on the bottom plate frame units and are butted with a mobile device for conveying the side wall total assemblyframes; the guiding and supporting units are mounted on the bottom plate frame units and are used for correcting positions of the side wall total assembly frames, supporting and positioning the side wall total assembly frames; the positioning and clamping stand column units are vertically mounted at corners of the bottom plate frame units and are used for clamping and fixing the side wall total assembly frames; clamp components and electrical quick inserting units are arranged at the upper parts of the positioning and clamping stand column units. According to the steel structure system, the guide rail units are arranged, can be conveniently matched and are capable of smoothly conveying the side wall frames into stations of the system; the guiding and supporting units are arranged, so thatthe side wall frames can be accurately adjusted to predetermined stations; the positioning and clamping stand column units are arranged and are used for clamping and fixing; the positioning manner issimple and reliable; the repeated positioning accuracy is high; the automobile body welding quality is improved.

Description

technical field [0001] The invention relates to a body-in-white welding and assembling production line of a complete vehicle factory, in particular to a steel structure system for precise positioning of a side wall assembly frame. Background technique [0002] During the general assembly of the body in white, the side panel assembly needs to be moved to the body assembly station for welding and assembly with the lower body. Due to the vigorous development of domestic automobiles, while various automobile factories are constantly launching new models, they also put forward higher requirements for equipment suppliers. The production line is required to have high tempo, high flexibility, and high stability. Different car models are integrated in one automatic station workstation. It is necessary to ensure the repeated positioning accuracy and welding of the side panel fixtures of each car model when they are flexibly switched at the final welding station. quality. At present,...

AI Technical Summary

Problems solved by technology

At present, each manufacturer has its own positioning equipment for the side wall fixture of the general assembly, but there are various shortcomings, such as single correspondence to the side wall fixture of the general assembly, high equipment cost, thick and complex mechanism, low repeatability, and large noise and inconvenient maintenance

[0003] Chinese patent CN 104842106B discloses a body side wall assembly device and a body side wall assembly system and method, wherein the body side wall assembly of the device includes a base, a sliding seat and a side wall clamp platform, and the base is provided with There is a guide rail on which the sliding seat is movably arranged, the side enclosure clamp platform is vertically fixed on the sliding seat, and a clamping mechanism is provided, which can receive and clamp the vertical The side wall assembly in a straight state, but the positioning accuracy of this device is relatively low, and the adjustment after the processing equipment enters the station is relatively limited, which cannot meet the needs of high-quality production
