Automatic assembling system for rotor parts of rotary machine

Abstract

The invention discloses an automatic assembling system for rotor parts of a rotary machine. The system comprises a base station and two rectangular coordinate system robots which are arranged in mirror symmetry. Each of the rectangular coordinate system robots comprises an X-axis slide rail, a Y-axis slide rail and a Z-axis slide rail, wherein the X-axis slide rail is fixedly connected to the upper surface of the base station, the lower end of the Z-axis slide rail is slidably connected to the X-axis slide rail through a Z-axis slide block, the side wall of one side of the Y-axis slide rail isslidably connected to the Z-axis slide rail through a Y-axis slide block, and the Y-axis slide rail is connected to an electric tightening shaft through an electric tightening shaft slide block. Theautomatic assembling system for the rotor parts of the rotary machine also comprises a first n-shaped clamp, a second n-shaped clamp and a third n-shaped clamp which are successively arranged along the direction of axis of symmetry of the two rectangular coordinate system robots. The system disclosed by the invention can tighten bolts according to different specifications of bolts, different reeldimensions, different tightening parameters and the like, and controls the bolt tightening process precisely.

Description

technical field [0001] The invention belongs to the field of bolt assembly and relates to an automatic assembly system for rotor parts of rotating machinery. Background technique [0002] The connection structure of rotating mechanical rotor parts uses a large number of fastening bolts. In the actual assembly process, aero-engine failures caused by unreasonable bolt assembly processes occur from time to time. Therefore, the quality control requirements for bolt connection assembly during assembly are very high high. Since the main assembly work of the bolted joint is the bolt tightening operation, the equipment and process of bolt tightening play a key decisive role. [0003] In the assembly process of the connecting structure of the rotating machinery rotor parts, manual operations are basically used, so the assembly quality is greatly affected by human factors, and the consistency of assembly and manufacturing is not ideal. In terms of the fastening process of the thread...
