[CN 201710818434.6] Electric servo leveling device for beam of large hydraulic press
[CN 201710818434.6] Title of electric servo leveling device for beam of large hydraulic machine: Application number of electric servo leveling device for beam of large hydraulic machine: CN 201710818434.6 Applicant: Jiangsu Institute of Technology Application Date: 2017-9-12 Patent Type: Application for Invention The present invention relates to a large hydraulic mechanism, in particular to an electric servo leveling device for beam of large hydraulic machine. An electric servo leveling device for a beam of a large hydraulic machine includes a beam and four hydraulic leveling devices connected to the lower end surface of the beam. The four hydraulic leveling devices are respectively arranged at the four corners of the beam. The leveling device includes a plunger cylinder for rough adjustment and an electric hydraulic servo cylinder for fine adjustment. The bottom end of the electric hydraulic servo cylinder is fixedly connected with the top end of the plunger cylinder. This application proposes a large-scale hydraulic machine beam electric servo leveling device, which can complete the coarse leveling and fine-tuning leveling of the hydraulic machine beam, improve the leveling accuracy of the hydraulic machine beam, and broaden the application field of hydraulic leveling technology.
