Description

technical field

[0001] The invention relates to a testing tool for auto parts, more specifically, to a portable online hole position testing device. Background technique

[0002] Due to the needs of weight reduction, energy saving and safety improvement of automobiles, the strength of automobile steel plates is required to be higher, and the tensile strength of automobile threshold steel plate materials has been increased from 440MPa to 1180MPa. With the significant increase in material strength, the difficulty of material processing has also increased, while the accuracy requirements for hole positions on parts have remained unchanged. Therefore, it is necessary to increase the frequency of inspections to strengthen continuous and effective monitoring of product quality during mass production.

[0003] The hole position accuracy between the multiple pre-punching dies on the threshold type rolling production equipment is affected by the transmission accuracy of the equipment...
