Description

Technical Field

[0001] The utility model relates to the technical field of machine tools for vibration electrolytic machining of integral blade disks, in particular to a three-axis linkage component. Background Art

[0002] The integral blisk is a new type of structural component designed to meet the needs of high-performance aircraft engines. It integrates the engine rotor blades and the wheel disc into one, eliminating the tenons, mortise and tenon grooves and locking devices in traditional connections, reducing the structural weight and the number of parts, avoiding tenon airflow losses, improving aerodynamic efficiency, and greatly simplifying the engine structure.

[0003] Vibration electrolytic machining machine tools are a special machining method that uses the principle of electrochemical anodic dissolution of metal in electrolyte to shape the workpiece. During machining, the workpiece is connected to the positive pole of a DC power supply, and the tool is connected to the negative pole, with a small gap between the two poles. The electrolyte flows through the gap between the poles, forming a conductive path between the two poles and generating current under the power supply voltage, thereby forming electrochemical anodic dissolution. As the tool is continuously fed relative to the workpiece, the workpiece metal is continuously electrolyzed, and the electrolysis products are continuously washed away by the electrolyte. Eventually, the gaps between the two poles tend to be consistent, and the workpiece surface forms a shape that is basically similar to the tool working surface.

[0004] In the process of processing the integral blade disk, a three-axis linkage component will be used. The three-axis linkage machining center is a multi-axis linkage CNC machine tool, which consists of a machine body, a workbench, a feed system, a spindle box, etc. Among them, the machine body is the foundation of the entire machining center, which is equivalent to a bracket. The workbench is responsible for locking and fixing the processed parts on it, the feed system provides equal movement capabilities in all directions, and the spindle box controls the movement path of the machining tool. The feed system is a key part of the CNC machine tool and is also one of the most important features of the three-axis linkage machining center that is different from other CNC machine tools. Through the feed axis, the workpiece can move in three directions, including the X axis, Y axis and Z axis.

[0005] In the process of operation and movement of each structure of a conventional three-axis linkage assembly, there will be a certain range of effective movement through the guide rail. However, during the movement, when the drive unit at one end of the guide rail fails, it may cause unnecessary structural collision of the slider at both ends of the guide rail, thereby causing damage to the hard structure.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a three-axis linkage assembly is proposed. Utility Model Content
