[0001] The utility model relates to the field of inspection tools, in particular to a inspection tool for automobile special-shaped parts with stable fit. Background Art

[0002] The car reflector is an important component in the car lighting system. Because its special special-shaped structure affects the projection effect of the car lights and other functions, its appearance processing quality needs to be strictly controlled. Therefore, after the shaping process is completed, it is also necessary to test the various structural dimensions and gap deviations between structures on the reflector to ensure that the reflector fully meets the quality requirements and can perfectly match other parts of the car.

[0003] The Chinese utility model patent with the existing announcement number CN216115954U discloses a kind of automobile reflector inspection fixture, which includes a base, a fixed measuring block, a movable measuring block, a fixing device, a tightening device, and a measuring reference block arranged on the base; the movable measuring block, the fixing device, and the tightening device are interspersed between multiple fixed measuring blocks, and the fixing device is arranged relative to the movable measuring block and the tightening device. The present application makes the detection and positioning more accurate through the arrangement of the measuring reference block and the fixing device, and makes the installation of the reflector more convenient through the arrangement of the movable measuring block and the tightening device, and the overall structure is simple, compact, easy to operate, and can quickly measure and evaluate the relevant dimensional relationship of the detection parts, thereby improving the assembly efficiency of the product. When the reflector is detected, the reflector needs to be firmly fixed on the detection table. Most of the inspection fixtures in the prior art only have fixed measuring blocks, and the installation of the reflector is very inconvenient, which affects the efficiency of product production inspection and cannot be detected quickly and accurately.
