[CN 201610378860.8] Universal automatic coaxial mechanism for oil cylinder of numerical control plate shearing machine
[CN 201610378860.8] Title of a CNC shearing machine oil cylinder universal automatic coaxial mechanism: Application number of a CNC shearing machine oil cylinder universal automatic coaxial mechanism: CN 201610378860.8 Applicant: Aike (Suzhou) Machinery Co., Ltd. Application Date: 2016-6-1 Patent Type: Application for the Invention The present invention discloses a CNC shearing machine oil cylinder universal automatic coaxial mechanism, including a shearing machine frame body, which is fixed with an oil cylinder through bearing wear resistance, the oil cylinder is connected with a synchronous twist shaft of a driving component. The lower end of the piston rod of the oil cylinder is provided with a ball bearing. The ball bearing is fixed by a lower fixing bracket installed on the frame body of the shearing machine. The piston rod of the oil cylinder is sleeved with an upper tool holder. The oil cylinder is fixed with a bracket. The bracket is fixed with a universal cross shaft. The universal cross shaft is fixed on the frame body of the shearing machine. In the invention, the lower end spherical surface of the oil cylinder is mechanically matched with the universal cross shaft to automatically adjust the wear caused by the shearing reaction side force on the oil cylinder, so that the center of the oil cylinder piston rod and the center of the inner wall of the oil cylinder are automatically coaxially adapted, and the influence of the reaction side force in the shearing process, the welding stress deformation of the frame and the assembly error of the oil cylinder on the oil cylinder is effectively solved.
