Abstract

The invention relates to a multi-degree-of-freedom micro-drill test bed. The multi-degree-of-freedom micro-drill test bed comprises a rack, a position adjusting mechanism capable of performing vertical movement, transverse movement and angle adjustment and connected to the rack, a drilling machine mechanism mounted on the position adjusting mechanism, a rock sample box arranged at the bottom of the rack and arranged directly facing the lower part of the drilling machine mechanism, and a mud pit arranged at the bottom of the rack, communicating with the rock sample box and connected with a mudpump, and the mud pump communicates with the upper end of the drilling machine mechanism. The problems that in the prior art, a micro-drill experiment table cannot be adjusted according to the relative positions of a rock sample and a drilling tool and the drilling requirement, and the experiment requirement is difficult to meet are solved.

Description

technical field [0001] The invention relates to the field of drilling, in particular to a multi-degree-of-freedom micro-drilling test bench. Background technique [0002] In recent years, with the continuous popularization of shield construction technology in my country and the exploration and development of deep resources, the requirements for drilling depth are getting deeper and deeper, and the economic cost of exploration is also getting higher and higher. Both drillability and abrasiveness directly determine the economic cost of exploration. For a long time, parameters such as drill bit aging, life, wear, rock drillability, and abrasiveness have been summarized based on the actual drill bit wear and tear data at the drilling site. In order to obtain rock properties and improve construction technology. However, the field operation conditions are complex, the environmental factors have a great influence, and the randomness of human operation makes the data obtained on th...
