Abstract

The utility model relates to a rotary impact ultrasonic rock grinding device driven by a single energy flow, which relates to an ultrasonic rock grinding device. The present invention aims to solve the problem that with the increase of the grinding depth of the existing impact ultrasonic rock grinding device, the grinding debris is not easy to be removed, and the accumulated grinding debris affects the subsequent grinding efficiency. The vertical-torsion composite piezoelectric transducer of the present invention is connected to the front end of the grinding shell assembly, the copper sleeve is installed at the inner rear end of the grinding shell assembly, and the grinding rod is horizontally installed in the grinding shell assembly. The grinding head is installed on the connecting piece of the grinding head, the front end of the grinding rod is in contact with the impact head of the longitudinal-torsional composite piezoelectric transducer through the free mass block, the rotor is sleeved on the front end of the grinding rod, and the preload spring is sleeved on the rotor , the recovery spring is set on the grinding rod, and the rear end of the recovery spring is in contact with the inner end surface of the copper sleeve. The invention is used in the field of deep space exploration.

Description

technical field [0001] The invention relates to an ultrasonic rock grinding device, in particular to a rotary impact ultrasonic rock grinding device driven by a single energy flow, which belongs to the technical field of deep space detection. Background technique [0002] Asteroids are the products left over from the early days of the formation of the solar system 4.5 billion years ago, and have well preserved the information on the early formation and evolution of the solar system. For the deep space exploration of asteroids, the history of the solar system can be better reproduced; in addition, since asteroids may contain a huge amount of mineral and fuel resources, this may be an effective solution to the earth's increasingly scarce various resources. Method. Therefore, deep space exploration is an area in which major aerospace countries invest a lot of manpower and financial resources to compete. At present, the most direct and effective way in the field of deep space ...
