Abstract

The invention discloses an experiment table for simulating the micro-drilling operation in the vacuum and waterless condition. The experiment table comprises a vacuum cavity, a drill pipe and a rock sample holder. The rock sample holder is arranged in the vacuum cavity. One end of the drill pipe is inserted into the vacuum cavity and is provided with a drill bit. The end of the drill pipe, inserted into the vacuum cavity, is right facing the rock sample holder. A gap between an opening of the vacuum cavity and the drill pipe is sealed by a sealing device, wherein the opening is used for the insertion of the drill pipe. By means of the experiment table, the vacuum and waterless drilling condition in the outer space can be simulated on the ground, so that the rock drilling test of small-size bits can be conducted. Through collecting the data of rock-smashing effect, drilling parameters, drill-bit temperature rise and the like, the temperature-rise characteristics of a drill bit in the vacuum and waterless condition, the influences of the drilling parameters on the temperature rise of the drill bit and the drilling and coring performances of rocks can be studied. Therefore, the experiment table can be used for guiding the design of the structure of a coring bit and guiding the selection of drilling parameters. In this way, the experiment table provides a basis for improving the coring efficiency and lowering the power consumption of the rock-smashing process.
