Description

Technical Field

[0002] At present, with the accelerated development of modern industrialization, mechanical automation has become a social trend. In industrial production, the main operation of operators is manual work, and there are two main types of manual work: First, use robots or some non-standard equipment to realize automatic handling and loading and unloading of products; second, use automatic measuring equipment to reduce manual operation in product measurement and data binding analysis; that is, manual operation time is to load and unload equipment and record product measurement. Only by carrying out the above two manual operations at the same time can the use of personnel in the manufacturing industry be reduced to a greater extent, thereby reducing labor costs for factories, improving the competitiveness and profit margins of enterprises, and ultimately creating more wealth for society.

[0003] At present, manual measurement is generally used to measure the runout and verticality of the turbocharger intermediate housing, that is, manually turning the workpiece; first, visually checking the micrometer to determine whether the workpiece is qualified.

This measurement method can neither achieve 100% data recording, nor bind information with the workpiece QR code. Therefore, it is particularly important to develop a set of equipment that automatically measures the runout and verticality dimensions of the intermediate housing and automatically stores the bound data. As a result, the production information of the workpiece can be traced, the outflow of such defective products and customer complaints are prevented, and customer satisfaction is improved.
