Abstract

The invention provides large linkage digital control rotation equipment for a bolt drawing machine. The large linkage digital control rotation equipment comprises a body, wherein a main shaft and a sensor are arranged on the body, a worm wheel is arranged on the main shaft and meshed with a worm rod, a working platform is arranged at the uppermost end of the body, the worm rod is connected with a servo motor through a coupler, and is a dual-screw pitch gradually-thickening worm rod, a worm wheel hub is fixedly arranged on the worm wheel and fixedly connected with the working platform, a coder is arranged on the working platform, a guide rail is arranged at the lower end of the working platform, a wear plate is arranged between the guide rail and the body, a plurality of pairs of brake blocks are uniformly arranged below the working platform and are fixedly connected with the working platform, a piston rod is arranged at the upper ends of the brake blocks and penetrates through the brake blocks to be connected with a piston in a hydraulic cylinder, a disc spring is arranged between the piston rod and the brake blocks, and a brake column is arranged between the brake blocks and the piston. The rotation equipment provided by the invention is capable of meeting processing requirements on bolt drawing machines for a nuclear power plant and other various large-size and super-heavy workpieces.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a large-scale linked numerical control rotary device for a bolt tensioning machine. Background technique [0002] At present, CNC boring machines and milling machines are used to process parts and components. Some CNC boring machines and milling machines use CNC platforms that match the equipment for rotary indexing processing, but the diameter of the platform is small, generally 2.5m, and the weight it can bear is also very high. Less, generally 10 tons, for large workpieces with a weight of more than 10 tons and a diameter of more than 2.5m, the processing needs cannot be realized, which limits the processing range of CNC boring machines and milling machines. Especially for the bolt tensioning machine used in nuclear power plants, the machining accuracy is required to reach 0.15mm, the concentricity must reach 0.1mm, the parallelism must reach 0.2mm, the maximum diameter of...
