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

Example Embodiment

[0034]As shown in Figures 1 to 5, a gantry frame used for car body-in-white performance testing of the present invention includes a cross beam 2, a longitudinal beam 3, a truss structure square column 4, a clamping device 5 and a plurality of T The mounting base 1 of the groove 11, the truss structure square column 4 is provided with four pieces and is arranged in a rectangular shape. Each truss structure square column 4 consists of four vertical rods 42, multiple horizontal rods 43, and four vertical rods 42 at the bottom. The bottom plate 41 and the top plate 44 arranged on the top of the four vertical rods 42 are constituted. Compared with the conventional round steel pipe, square steel pipe, I-beam and other columns in the prior art, the truss structure square column 4 not only reduces the consumables, but also guarantees The whole device has sufficient rigidity. Each bottom plate 41 is fixed to the installation base 1 by fasteners placed in the T-slot 11, so that the spacing ...

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 ...
