Rotary impact type ultrasonic rock grinding device driven by single energy flow

Abstract

The invention discloses a rotary impact type ultrasonic rock grinding device driven by single energy flow, and relates to an ultrasonic rock grinding device. The impact type ultrasonic rock grinding device aims at solving the problems that according to an existing impact type ultrasonic rock grinding device, along with the increase of the grinding depth, abrasive dust is not prone to being removed, and the accumulated abrasive dust affects the subsequent grinding efficiency. A longitudinal-torsional combined type piezoelectric transducer is connected with the front end of a grinding shell assembly, a copper sleeve is installed at the rear end of the interior of the grinding shell assembly, a grinding rod is horizontally installed in the grinding shell assembly, a grinding head is installedon a grinding head connecting piece, the front end of the grinding rod makes contact with an impact head of the longitudinal-torsional combined type piezoelectric transducer through a free mass block, a rotor sleeves the front end of the grinding rod, a pre-tightening spring sleeves the rotor, a restoring spring sleeves the grinding rod, and the rear end of the restoring spring contacts with theinner end face of the copper sleeve. The device is applied to 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 ...
