Embodiment Construction

[0028] When the inventor made the design, considering that in the current machining of the tongue and groove of the turbine disk, since a contour of the groove is a curve (in the XY plane), the chip formed during the cutting is a curved surface. In the ultrasonic vibration assisted processing, the tool When vibrating relative to the workpiece along the x and y axes, interference will occur. There is no guarantee that the cutter teeth will be out of contact with the workpiece within a period of vibration frequency.

[0029] In order to solve the above interference problem, in the cutting vibration transmission system, the inventor hopes to control the vibration transmission system in the X, Y, and Z directions to achieve no motion interference, that is, to achieve the tool and the workpiece within a part of the cycle. It is completely out of contact in the x, y, and z directions. Therefore, according to the vibration characteristics, the inventor designed this device to controlla...

Abstract

The invention discloses a high-amplitude vibration amplitude variable rod for ultrasonic high-speed vibration auxiliary processing. The high-amplitude vibration amplitude variable rod is a whole pieceand includes a main body rod and a plurality of amplitude variable rod bodies, the main body rod is a diameter variable rod arranged in the length direction of a tool workbench, the amplitude variable rod bodies are the amplitude variable rod bodies with the rod diameter reducing from the tool workbench to a cutter pulling cutter box, and the bottom end of each amplitude variable rod body is connected to the variable diameter position of the main body rod. When used, the energy can be concentrated on a smaller area because the rod diameter of each amplitude variable rod body reduces from thevibration penetrating-in end to the transferring-out end, the vibration is amplified and transmitted to the cutter pulling cutter box and a pulling cutter, the high vibration speed is achieved, high vibration speed requirements when a turbine disk tenon groove is processed are met, and the surface quality is improved; and the amplitude is enlarged, the fact that cutter teeth are completely separated from a workpiece within a vibration frequency cycle, the possibility of a tool hitting the workpiece when the tool is returned from a non-cut-off material is avoided, the machining efficiency can be improved, the damage caused by the interference to the tool can be reduced, and the service life of the tool is prolonged.

Description

Technical field [0001] The invention belongs to the field of broaching processing equipment, and in particular relates to a large-scale vibration horn used for ultrasonic high-speed vibration auxiliary processing. Background technique [0002] In the machining of the tongue and groove of the turbine disk, due to the complex surface of the tongue and groove and the high precision requirements, in order to meet the requirements, broach with different tooth shapes and geometric contours are required in the machining process, and the system vibration during the machining process and the tool wear There are more stringent requirements. The material of the additional turbine disk is a nickel-based alloy, which is difficult to process and other factors, which will affect the use of high-efficiency broaching of the turbine disk tongue and groove. The cutting force in broaching is much larger than that of ordinary turning and milling processes, which puts forward higher requirements on th...
