Abstract

The invention relates to the technical field of digital measurement, in particular to a stamping steel plate bending slope multi-station automatic detecting system. The system comprises a detecting tooling mounted on a punching press body and a detecting system used for detecting data analysis. Receiving slides are arranged on the outer surfaces of sliding rails correspondingly. A suspending supporting frame is mounted between the two receiving slides. A laser distance measuring head is mounted at the bottom end of a dial scale. The stamping steel plate bending slope multi-station automatic detecting system is designed based on triangulation, it is determined that the method can meet angle measuring requirements through error analysis, distance measuring is achieved through the laser distance measuring head, all sides required in the triangulation are obtained, the bending angle is obtained through calculation based on a formula, devices are reasonably designed, the laser distance measuring head is driven to move to all stations of a punch press, and the steel plate bending slope at all stations is automatically measured.

Description

technical field [0001] The invention relates to the technical field of digital measurement, in particular to a multi-station automatic detection system for the bending slope of stamped steel plates. Background technique [0002] The web is a key internal component of the telescopic arm of a large truck-mounted crane, and its manufacturing process level directly determines the performance and fatigue life of the mechanical telescopic arm. In recent years, the demand for large and heavy industrial equipment has increased sharply in heavy industry, cargo yards, ports, warehouses, etc., and there are new development needs in terms of lifting capacity and maneuverability. Therefore, the development of truck-mounted cranes has put forward higher production and processing requirements for large-scale equipment that manufactures key components of the telescopic boom of truck-mounted cranes. [0003] At present, the large and heavy punching machines in China basically meet the proce...
