[0002] With the continuous development of the automobile industry, consumers have increasingly high requirements for the appearance quality of automobiles. The front door bright strip of an automobile, as an important appearance decoration part, not only improves the overall aesthetic appearance of the vehicle, but also plays a certain protective role. Therefore, the detection of the size precision, shape, strength and other performance indicators of the front door bright strip of an automobile is particularly important.

[0003] In the prior art, the detection of the automobile bright strip mainly relies on manual detection using a detection tool. For example, Chinese patent application "202111581736.9", publication number CN114413729A, discloses a detection tool including a base, a fixing mechanism for fixing the bright strip on the base; the bright strip includes an outer contour, an inner contour, a surface contour and a tail end connecting hole; the detection tool further includes a first checking mechanism for detecting the outer contour and the inner contour, a second checking mechanism for detecting the surface contour, and a third checking mechanism for detecting the tail end connecting hole; the fixing mechanism includes a clamp, a plurality of support tables fixed to the base for supporting the bright strip, and a pressing mechanism for pressing the bright strip on the support table; the third checking mechanism is a detection needle located on the base.

[0004] For another example, Chinese patent application "A detection tool for an automobile bright strip", publication number CN213181036U, discloses a detection tool including a base plate, a placement plate obliquely installed on the base plate through a plurality of support blocks, a plurality of placement blocks fixedly installed on the placement plate, a plurality of pressing mechanisms, a plurality of clamping mechanisms and a plurality of detection mechanisms, the automobile bright strip is placed on the placement blocks, and the automobile bright strip is fixed on the placement blocks through the plurality of pressing mechanisms, the plurality of clamping mechanisms and the plurality of detection mechanisms.

[0005] In summary, the current automobile bright strip detection tool still has some deficiencies: most detection tools only detect a single performance, lack integrated design, resulting in scattered detection process and low efficiency; the existing detection mechanism relies on manual adjustment and multiple clamping, which requires high skills of the operator and is prone to introduce human error; CONTENT OF THE UTILITY MODEL

[0006] The technical problem to be solved by the present application is to provide a front door bright strip detection tool for an automobile, which can realize multi-parameter detection in a single tool, simplify the operation process and improve the detection accuracy.

[0007] The technical scheme adopted by the present application is: the automobile front door bright strip detection fixture comprises a base plate, two groups of detection assemblies are fixedly arranged on the base plate, the two groups of detection assemblies are symmetrically arranged, the detection assembly comprises a base fixedly arranged on the base plate, a mounting groove matched with the bright strip to be detected is arranged on the top surface of the base, a plurality of fixing positions are arranged on the mounting groove, a limiting block matched with the bottom surface of the bright strip to be detected is arranged at the fixing position, a pressing assembly is arranged directly above the fixing position, at least one fixing position is provided with a side pushing assembly, and the end portion of the side pushing assembly penetrates through the base and is embedded in the mounting groove to act on the side surface of the bright strip to be detected.

[0021] In some embodiments of the application, four fixing positions are provided on the mounting groove, two of which are provided with side openings communicating with the mounting groove, and the side pushing assembly extends into the mounting groove through the side openings, and the side pushing assembly moves along a direction perpendicular to the mounting groove under stress.

[0022] The side openings provided at the fixing positions allow the side pushing assembly to directly act on the side surface of the bright bar laterally, and the lateral size or deformation resistance detection can be completed without disassembly, thereby expanding the functional integration; the side pushing direction is perpendicular to the mounting groove, ensuring that the mechanical test direction is accurately controllable, and the data reliability is high.

[0025] In some embodiments of the present application, the other end of the base is provided with an end detection assembly, and the end detection assembly is provided with two laterally arranged second detection holes. The double second detection holes are designed for the bright bar tail end connecting hole or lateral feature, and the hole position accuracy is directly detected by a go-no-go gauge or a probe, thereby supplementing the detection capability of the end critical dimension, avoiding missed detection, and ensuring the compatibility of the bright bar assembly.
