Gantry type frame for detecting white body performance of automobile

Abstract

The invention discloses a portal frame used for automotive body-in-white performance detection. The portal frame comprises cross beams, stringers, truss structure square columns, a clamping device and a mounting base with a plurality of T-shaped grooves. Four truss structure square columns are arranged in a rectangle, each truss structure square column consists of four vertical bars and a plurality of cross bars, a plurality of the cross bars are arranged in parallel on the column surfaces of the truss structure square columns and connected between two vertical bars, the cross bars on the symmetrical column surfaces of the truss structure square columns are symmetrically arranged, the bottom of each truss structure square column is provided with a base board which is fixed on a mounting base by fasteners arranged in the T-shaped grooves, two cross beams and two stringers are provided and respectively connected with the cross bars on the corresponding truss structure square columns by a clamping device. The portal frame used for the automotive body-in-white performance detection has the advantages of wide application range, enough overall strength and rigidity, convenient disassembly and assembly, and convenient climbing and regulation for operators.

Description

technical field [0001] The invention relates to the field of automobile body-in-white performance detection equipment, in particular to a gantry frame used for automobile body-in-white performance detection. Background technique [0002] When testing the performance of the automobile body-in-white, it is necessary to install, fix, and hang the body-in-white, and to install various types of measurement aids around the body-in-white. Therefore, it is necessary to design a gantry type that can be installed (or hung) for various types of vehicles. frame. At present, the units that have the ability to test the performance of the body adopt different strategies, and the designed frameworks are also different. Generally, it is a simple fixed frame structure, which is inconvenient to disassemble and adjust. When testing a small car, the combination of a large frame and a small car appears to be uncoordinated in support rigidity. When testing a large car, it is difficult to install ...

Problems solved by technology

Generally, it is a simple fixed frame structure, which is inconvenient to disassemble and adjust. When testing a small car, the combination of a large frame and a small car appears to be uncoordinated in support rigidity. When testing a large car, it is difficult to install it in place; there are also units A combined frame with a fixed main frame (larger) and movable attached beams is designed. This structure has certain mobility and can be adjusted within a certain range, but the moving attached beams will destroy the overall rigidity. Some of the uprights are made of profiles, such as round steel pipes, I-beams, square steel pipes, etc., which are not convenient for operators to climb, and consume a lot of materials; in order to improve the overall rigidity of the frame, temporary welded diagonal braces are used as auxiliary supports. On the one hand, the reusability is not good, which will affect the follow-up test; on the other hand, the on-site welding will cause the frame to deform
