Problems solved by technology
The rear longitudinal beam of an automobile is welded by multiple parts. After welding, the shape and size of the parts are irregular, and it is not easy to measure directly manually.
The use of inspection tools can achieve the purpose of fast positioning and convenient inspection. At present, there is no special inspection tool, and the inspection has to be carried out manually through the measuring tool. The detection accuracy is difficult to guarantee, and the detection efficiency is low.

Embodiment Construction
[0011] Such as figure 1 As shown, the automobile rear longitudinal beam welding inspection tool of the present invention includes a base 3, and the base 3 is arranged on a mobile support 1 with rollers. , overturn assembly 5, compactor s1-s3, main positioning pin H, secondary positioning pin h, detection pin h1-h12; the distance between detection pins h1-h12 and the installation angle of each detection pin h1-h12 are the same as those to be detected The position of the detection hole of the rear longitudinal beam of the automobile corresponds to the position; the distance between the main positioning pin H and the secondary positioning pin h corresponds to the position of the positioning point of the rear longitudinal beam of the automobile to be detected.
[0012] During detection, firstly open the press clamp and flip assembly 5, and open the working surface. Align the parts to be tested with the main positioning pin H and the secondary positioning pin h, and place them on ...

The invention discloses a welding detector for a rear side member of an automobile. The welding detector comprises a base, wherein the base is arranged on a moving bracket with idler wheels; the moving bracket can quickly move the whole detector through the idler wheels arranged at the bottom of the moving bracket, and the detector is convenient to transfer; by virtue of a guide rail assembly, a detection mechanism mounted on the guide rail assembly can move in a certain space on the detector, and detected parts are convenient to mount and dismount; the base is used for mounting a detection assembly; a detector body is used for supporting and detecting the parts; an overturning assembly is used for detecting the end faces of the parts and mounting a dial indicator; a main positioning pin and an auxiliary positioning pin are used for positioning the parts during mounting, so that the parts are accurately positioned and are accurately detected; a detection pin is used for detecting the positions of holes of the detected parts; a quick presser is used for quickly pressing the detected parts, so that inaccurate detection caused by loosening of the parts is avoided. The detector has the functions of quick positioning and simple operation, and can be used for accurate detection.
Description
technical field [0001] The invention relates to a detection fixture, in particular to a welding inspection fixture for rear longitudinal beams of automobiles. Background technique [0002] Along with the continuous increase of the quantity of automobile, various traffic accidents also emerge in an endless stream, wherein the incidence rate of rear-end collision accident is higher. The rear longitudinal beam of the car plays an extremely important role in the rear-end collision accident. It can absorb the collision energy through its own crushing deformation and bending deformation, and buffer the impact force generated during the collision, thereby effectively protecting the safety of the passengers in the car. The rear longitudinal beam of an automobile is welded by multiple parts. The shape and size of the welded parts are irregular, and it is not easy to measure directly manually. The use of inspection tools can achieve the purpose of fast positioning and convenient insp...
