Abstract

The invention provides a test bench for testing the comprehensive performances of an ultrasonic drilling device. The frame of the test bench is shaped like L, and an impact force sensor is mounted onthe bottom surface of the frame. A rock sample is fixedly mounted on the impact force sensor, and the ultrasonic drilling device is vertically placed on the upper surface of the rock sample. The ultrasonic drilling device is fixedly connected with a loading platform, and the loading platform is fixedly connected with an adjusting mechanism. A rotating motor is mounted on a vertical column of the frame, and a ball screw is fixed inside the vertical column of the frame through a screw fixed end support seat and a screw movable end support seat. The rotating motor drives the ball screw to rotatethrough a shaft coupler, and a screw nut is fixed on the ball screw in a sleeved manner and is fixedly connected with the adjusting mechanism. The test bench solves a problem that the parameters, suchas the load spring stiffness, the loading force, the return spring stiffness and the restoring force, cannot be measured in the prior art, and proposes the test bench for testing the comprehensive performances of the ultrasonic drilling device, which can perform the testing of the influence of the above parameters on the drilling efficiency.

Description

technical field [0001] The invention specifically relates to an ultrasonic drilling sampling test platform, which belongs to the field of extraterrestrial celestial body detection and sample collection and testing. Background technique [0002] Deep space exploration is one of the most active scientific fields in recent years. Studying the geological information of extraterrestrial space helps 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. The quality of the ultrasonic drill, the stiffness of the loading spring, the loading force, the stiffness of the return spring, the restoring force, the quality of the free mass block, and the quality of the sampling drill affect the drilling efficiency of the d...
