Description

Technical Field

[0001] The present invention relates to the technical field of quality inspection, and more particularly to a quality inspection device for processing an electric lifter. Background Art

[0002] In the fields of automobiles, industrial lifting equipment, etc., the quality of electric lifters directly affects the safety and reliability of equipment operation, so its quality inspection after processing is extremely important. Traditional electric lifter quality inspection devices mostly use a single-dimensional mechanical pressure detection method, which can only perform simple pressure tests on the middle of the workpiece. It is difficult to simulate the complex force scenarios in actual use, and it is impossible to perform comprehensive inspections of local areas and corner positions. There are blind spots in the inspection, resulting in a high risk of missed detection of potential defects. At the same time, existing devices generally have the problem of low degree of automation, requiring manual participation in parameter adjustment and data recording. Not only is the inspection efficiency low, but it is also easy for human operation errors to affect the accuracy of the inspection results.

[0003] With the development of industrial automation and intelligence, the limitations of traditional inspection devices in multi-station switching, sensor collaborative monitoring, and data processing are becoming increasingly prominent. On the one hand, existing devices have difficulty in achieving automated switching between multiple inspection positions, such as the center, local area, and corners, and cannot meet the diverse inspection needs of electric lifters of different specifications, resulting in poor equipment versatility. On the other hand, their sensor configuration is single and lacks real-time collaborative monitoring of multiple parameters such as pressure, displacement, and angle, making it difficult to accurately determine the structural strength and defect type of the workpiece. Therefore, in order to solve the above problems, the existence of a quality inspection device for electric lift processing is crucial. Summary of the Invention
