Description

Flexible door assembly measurement tool

technical field

The utility model relates to the field of auto parts, more specifically, to the technical field of detection of auto parts.

Background technique

In the production process of auto parts, the parameter measurement of parts is an indispensable link. In the traditional measurement technology, contact measurement methods such as three-coordinate measurement and gage measurement are mainly used. These contact measurement methods have high requirements for the measurement environment and the temperature of the measurement site, and the measurement process is relatively complicated. At the same time, limited by the actual size and shape of the inspection tool and the actual size and shape of the parts, some positions on the parts cannot be measured or are difficult to measure, which affects the measurement range and measurement accuracy. In addition, due to the complicated steps of traditional contact measurement, in practical applications, its measurement efficiency, measurement frequency, measurement accuracy, measurement range, etc. have encountered bottlenecks, and can no longer adapt to the rapid development of the auto parts industry.

In recent years, optical measurement has gradually emerged as a non-contact measurement method. Optical measurements utilize common, safe light sources to perform measurements. Compared with the high-precision and high-environmental requirements of contact measurements such as traditional three-coordinate measurement and gage measurement, the optical measurement system has lower requirements for the environment and temperature, and can be applied in the workshop environment without special effects on the temperature gradient of the surrounding environment.

Although optical measurement can overcome the shortcomings of traditional contact measurement, for auto parts with complex shapes and relatively precise structures, how to fix these parts during the measurement process is also a problem that needs to be solved. For example, the outer covering parts on the car body such as the door assembly parts, its dimensional accuracy directly affects the appearance matching quality of the car body. In the process of measurement, on the one hand, it is necessary to firmly clamp the door assembly components, and on the other hand, it is necessary to avoid excessive clamping force on the door assembly components, resulting in deformation of the parts.

Detailed ways

Studying the structure of the door assembly components, it can be found that the door assembly components are mainly composed of outer panels, inner panels and reinforcements, and the outer panels and inner panels are connected together by undercuts and glue. The door components in the assembly state have relatively high overall stiffness. Tests have shown that the bottom undercut of the door assembly components is sufficient to support the weight of the entire door assembly components, and the resulting elastic deformation is also negligible. Vehicle door assembly components of different models and sizes all have the above-mentioned undercut feature, so the bottom undercut can be used as a support point for the vehicle door assembly component. After the bottom undercut supports the entire door assembly, all that remains is a mechanism to prevent the door assembly from toppling over.
