Description

Technical Field

[0002] pcf = part coordinate fixture, which is a part inspection fixture. In the automotive industry, this kind of inspection fixture is used to check the assembly processability of parts and their assemblies. On the main PCF inspection fixture, the side panel part is U-shaped sliding. When the side panel welding assembly is combined with the lower body welding assembly, the side panel welding assembly is required to be tested for a 3mm or 5mm gap before combination. Since the side panel part weighs 2T and is generally operated by one person, there are the following problems and shortcomings:

[0003] 1. During assembly, if the side panel interferes with the lower body, it is difficult to detect due to the large inertia of the side panel. The collision of the interference point between the two can easily cause damage to the workpiece and loss of precision.

[0004] 2. The inspector is usually a single operator. When pushing the side panel to position it at the 3mm or 5mm inspection position, there is a task to align the positioning pin. The position needs to be adjusted to insert the positioning pin. However, it is difficult to complete the positioning and fine-tuning of the 2T side panel by a single operator. It requires two people to operate and is time-consuming. Summary of the invention
