Two-side clamping type impact actuating device

Abstract

The invention provides a two-side clamping type impact actuating device which comprises a center cylinder, a guide section, an inner and outer connecting ring, a space cam and an impacted piece; the tail end of the center cylinder is connected with the guide section through the inner and outer connecting ring, and the space cam is arranged on the lower portion of the center cylinder in a sleeving mode and connected with the guide section through a bearing; an energy storage spring, an impact hammer, clamping sliding blocks, a sliding table and a reset spring are sequentially arranged in the center cylinder from top to bottom; the two clamping sliding blocks are arranged, a gap is formed between the two clamping sliding blocks, and the two clamping sliding blocks are both arranged in a sliding groove of the sliding table in a sliding mode; the impact hammer comprises an impact hammer body and an impact clamping block; and one end of an impacted piece is vertically inserted into the center cylinder from the upper end face of the center cylinder, sequentially penetrates through the energy storage spring, the impact hammer, the gap between the two clamping sliding blocks, the sliding table and the reset spring, and then extends out of the guide section. According to the invention, the impact actuation of the impacted piece of any configuration under the magnitude of the section size of 1*1 mm<2> is realized, and the springback phenomenon caused by impacting a hard object can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of extraterrestrial celestial body sampling and detection, and in particular relates to a two-side clamping type impact actuation device. Background technique [0002] The submerged detection of extraterrestrial celestial body profile is usually realized by auger drilling and impact penetration. The way of impact penetration has little disturbance to the star soil profile, which can better ensure the original state information of the profile, and is more conducive to the authenticity of the detection information. The submersion method of impact penetration generally uses a cylinder as the submersion matrix, and the sensor is arranged on the surface of the cylinder matrix, and the detection matrix is ​​penetrated into the star soil profile by means of impact or static pressure, but it requires a large Crowded spaces make penetration more difficult. [0003] Therefore, a detector with a thin shell structure ...

The submersion method of impact penetration generally uses a cylinder as the submersion matrix, arranges the sensor on the surface of the cylinder matrix, and penetrates the detection matrix into the star soil profile by means of impact or static pressure, but it requires a large Crowded space makes penetration more difficult

[0003]Therefore, a thin-shell structure is proposed instead of a cylinder as a detector for penetration. However, it is precisely because the cross-sectional size of the thin-shell structure is too small that conventional impact actuators cannot work perpendicular to the cross-section of the thin-shell structure
