Gap measurement tool and gap qualified rate measurement method

Abstract

The invention proposes a gap measurement tool and a gap qualified rate measurement method, which are well adapted to the batch-production internal and external decorations of a cab of a heavy truck. The measurement tool is a measuring ruler with a trapezoid structure. The surface of the measuring ruler is marked with standard scale, a gap lower limit deviation graduated line and a gap upper limit deviation graduated line. The measurement method can achieve the quick, convenient and accurate measurement of the gaps of the batch-production internal and external decorations of the cab of the heavy truck at lower cost through a simple structure, and can accurately determine at the highest efficiency whether the gaps of the internal and external decorations of the cab are qualified or not, greatly improves the detection efficiency of the internal and external decorations of the cab, and reduces the cost. Meanwhile, the measurement tool and the measurement method can be widely popularized and applied to the measurement of gaps of other products besides the internal and external decorations of the cab, and are good in market popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a gap measuring tool and a gap qualified measuring method, and more specifically relates to a gap measuring tool and a gap qualified measuring method for mass-produced interior and exterior trims of cabs of heavy trucks. Background technique [0002] With the upgrading of domestic heavy-duty truck consumption, consumers have higher and higher requirements for heavy-duty truck cabs, and the gap between the interior and exterior of the cab has become an important concern for consumers when choosing cars. At present, the general-purpose vernier caliper is mainly used to detect the clearance between the interior and exterior of the cab during the production process. This kind of interior and exterior clearance measurement based on the vernier caliper has the following defects in practice: (1) Since there are many gap measurement points for the interior and exterior of ...

Problems solved by technology

At present, the general-purpose vernier caliper is mainly used to detect the clearance between the interior and exterior of the cab in the production process. This kind of interior and exterior clearance measurement based on the vernier caliper has the following defects in practice: (1) Since there are many gap measurement points for the interior and exterior of the cab, ordinary Due to the influence of the size of the vernier caliper itself, some parts cannot be measured, so there are gap measurement blind spots, and the measurement quality cannot be guaranteed; (2) The gap measurement efficiency of the ordinary vernier caliper is low, and the vernier caliper needs to be precisely adjusted for each gap measurement , and the adjustment of the vernier caliper is more complicated, especially for the cab interior and exterior products with many measurement points in mass production. The gap value of the produced cab interior and exterior becomes very unrealistic, which greatly reduces the efficiency of gap measurement, and thus cannot guarantee the production cycle
