Abstract

The invention belongs to the technical field of machining and particularly relates to a molded surface constraint ultrasonic vibration auxiliary rotating abrasive flow finishing machining device. Thedevice comprises a constraint molded surface, an ultrasonic vibration device, a sleeve and a spindle tool shank. The upper end of the sleeve is connected with the spindle tool shank. The ultrasonic vibration device comprises an ultrasonic amplitude change rod and an ultrasonic transducer. The ultrasonic transducer is arranged in the sleeve, and the lower end of the ultrasonic transducer is connected with the upper end of the ultrasonic amplitude change rod. The wave nodal point of the ultrasonic amplitude change rod is connected with the lower end of the sleeve. The lower end of the ultrasonicamplitude change rod is connected with a workpiece. The workpiece is located in an inner cavity of the constraint molded surface. The molded surface rotation center line of the constraint molded surface is parallel to the axis of the workpiece. The constraint molded surface is filled with fluid abrasives over the workpiece. The surface to be machined of the workpiece is matched with the inner wall of the constraint molded surface. The molded surface constraint ultrasonic vibration auxiliary rotating abrasive flow finishing machining device can avoid the inlet and outlet differential pressure,improve the machining efficiency and surface smoothness of the workpiece, shorten the machining time, save the machining cost, achieves the purpose of machining without dead angles and ensure the surface shape precision of the workpiece.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to abrasive flow finishing, in particular to a surface-constrained ultrasonic vibration-assisted rotating abrasive flow finishing device. Background technique [0002] Abrasive streamlining is a process that uses polymer materials as a carrier, suspends cutting abrasives in it to form fluid abrasives, and deburrs, polishes, rounds, etc. through the surface of the workpiece under pressure. Abrasive flow machining is not limited by the geometric shape of the workpiece, and is suitable for processing complex surfaces such as various holes, profiles, and cross holes; it has high processing efficiency and good polishing effect; it is used in aerospace, weapons, steam turbines, textiles, molds, and hydraulic pressure. And other machinery industry has been widely used. [0003] However, due to the pressure difference between the inlet and outlet of the traditional abrasive flow...
