Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile detection, and in particular to a surface flatness detection device for aluminum profiles used in new energy vehicles. Background Art

[0002] With the continuous development of society, more and more new energy vehicles are entering every household. After the production of aluminum profiles for new energy vehicles, in order to ensure the production quality of the vehicles, testing equipment is needed to test the flatness of the aluminum profiles. In the prior art aluminum profile surface flatness detection equipment, the clamping assembly allows the aluminum profile mold plate to be placed between two clamping bars during use. After the placement is completed, the second motor is started to rotate the two tooth columns. The rotation of the two tooth columns drives the two clamping bars to gradually approach each other to fix the aluminum profile mold plate. After fixation, when one side of the aluminum profile mold plate needs to be detected, the servo motor can be started to rotate the U-shaped block. The rotation of the U-shaped block drives the aluminum profile mold plate to rotate. In this case, the user can adjust the detection surface of the aluminum profile mold plate very conveniently. However, during the inspection, the aluminum profile to be inspected needs to be loaded onto the mounting plate first and then inspected on the mounting plate. After the inspection, the inspected aluminum profile needs to be unloaded from the mounting plate and then reloaded to continue the inspection. This does not make full use of the loading and unloading time of the aluminum profile, thereby reducing the inspection work efficiency. Therefore, there is room for improvement.
