Ultrasonic auxiliary cutting device with cutter fine adjustment mechanism

Abstract

The invention discloses an ultrasonic auxiliary cutting device with a cutter fine adjustment mechanism. The ultrasonic auxiliary cutting device comprises the cutter fine adjustment mechanism and an ultrasonic vibration acoustics system; the cutter fine adjustment mechanism comprises a vertical plate vertically arranged on a base plate, and a dovetail sliding plate matched with the vertical plate; the vertical plate is connected with the dovetail sliding plate through a connecting plate; a screw rod is arranged in a connecting sleeve in the middle of the vertical plate through a screw nut; an index plate is arranged on the upper part of the connecting sleeve; a handle is arranged at the upper end of the screw rod; a supporting flange is fixedly connected with the connecting plate; the ultrasonic vibration acoustics system comprises an ultrasonic generator, an energy transducer, an amplitude transformer and an ultrasonic turning tool; and the ultrasonic vibration acoustics system is connected with the supporting flange through a fixing flange on the amplitude transformer. The ultrasonic vibration energy leakage of the device is lowest; by the cutter fine adjustment mechanism, the ultrasonic vibration acoustics system can move in the height direction; the fine mobile resolution is up to 0.01 millimeters; therefore, height adjustment of a tool nose of a cutter with an abraded blade and the precision cutting of a workpiece can be realized effectively.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an ultrasonic auxiliary cutting device with a tool fine-tuning mechanism. Background technique [0002] At present, the additional ultrasonic vibration cutting devices on ordinary lathes generally include two types that are directly clamped on the tool holder and directly installed on a small pallet. The structure of the former is too simple, and it is installed on the tool holder. The ultrasonic vibration node is difficult to control, resulting in a large loss of ultrasonic energy. This method is generally only used for the experiment of ultrasonic cutting principle; the latter becomes an independent system, avoiding the problems caused by inaccurate nodes. Energy loss, but in the actual processing process, due to tool wear and tool sharpening, it is often necessary to fine-tune the height of the tool tip. Since this type of device does not have the fun...
