Description

Technical Field

[0001] This utility model relates to the field of drive shaft detection technology, specifically a novel automotive drive shaft detection device. Background Technology

[0002] After the automotive driveshaft is processed, it is necessary to sample and test the hardness of the automotive driveshaft to reflect the quality of the automotive driveshaft. Cars are not only our advanced means of transportation, but also provide a hard shell to protect us. Therefore, there are strict requirements for car manufacturing, so that every car manufacturing process is meticulous.

[0003] In existing technologies, the parts to be inspected need to be fixed manually. When the parts are fixed manually, the efficiency is reduced and the device may be misoperated, resulting in an unstable fixation. Large impacts during inspection can damage the rigidly connected inspection equipment. Therefore, we propose a new type of automotive drive shaft inspection device. Utility Model Content
