Problems solved by technology

[0004] The invention solves the problem that the ultrasonic drills in the prior art are all equipped with free mass blocks, and needs to complete two contact collisions, and there is a certain degree of energy loss, and proposes an impact ultrasonic drill without free mass blocks, which saves It only needs to complete a collision once the free mass block is removed, which improves the energy transfer efficiency of the ultrasonic drill

Abstract

The invention provides an impact-type ultrasonic drilling device free of free mass blocks. A sampling drill is mounted at the front end of an variable-amplitude rod of the drilling device. A shell ismounted on the peripheries of the tail ends of the variable-amplitude rod and the sampling drill. A return spring is located in the shell and sleeves the tail end of the sampling drill. A rear cover plate is mounted on the periphery of the tail end of the variable-amplitude rod, and is connected with the shell. A elastic gasket is mounted between the rear cover plate and the shell, a piezoelectricceramic stack is located between the variable-amplitude rod and the rear cover plate, the rear end of the variable-amplitude rod passes through the piezoelectric ceramic stack, and an insulating sleeve is disposed between the piezoelectric ceramic stack and the variable-amplitude rod. The impact-type ultrasonic drilling device has the advantages that the problems that ultrasonic drilling devicesin the prior art are all provided with the free mass blocks, need to complete two contact collisions and cause energy loss are solved; according to the impact-type ultrasonic drilling device free of the free mass blocks, the free mass blocks are omitted, and only one collision needs to be completed, so that the energy transfer efficiency of the ultrasonic drilling device is improved; the ultrasonic drilling device has low weight, low drilling pressure and low power consumption.

Description

technical field [0001] The invention relates to an ultrasonic drill, in particular to an impact-type ultrasonic drill without a free mass block, and belongs to the field of ultrasonic drilling and sampling. Background technique [0002] Deep space exploration is one of the most active scientific fields in recent years. Studying the geological information of the extraterrestrial universe will help to explore the composition of the solar system and the origin of life. Drilling and sampling is an important way to obtain stellar soil samples in deep space exploration. Compared with drills driven by electromagnetic motors, ultrasonic drills have the advantages of small size, low power consumption, and low drilling pressure. [0003] Ultrasonic drills use high-frequency axial vibrations of piezoelectric transducers to vibrate and break rocks. Traditional ultrasonic drills consist of three core components: transducers, free mass blocks, and drilling tools. When the drill is workin...
