The utility model relates to
deep hole drilling equipment, which belongs to the technical field of drilling equipment and comprises a
machine body, a porous bearing plate mounted in the middle of the inner side of the
machine body, and a clamping mechanism, a drilling mechanism, a
cutting fluid circulating mechanism and a filtering mechanism which are mounted in the
machine body, the filtering mechanism comprises a filtering net plate movably arranged in the machine body and a square collecting box rotationally connected to the outer side of the filtering net plate and movably arranged in the matched machine body; according to the
cutting fluid recycling device, chippings in
cutting fluid can be filtered through the filter screen plate, the filtered
cutting fluid is subjected to heat exchange and cooling through the heat exchange
pipe, the
cutting fluid can be recycled after being filtered and cooled, the
cutting fluid at the bottom of the machine body can be stirred through rotation of the stirring mechanism, the cutting fluid can make more uniform contact with the heat exchange
pipe, and the heat exchange effect is improved; chippings on the top of the filter screen plate are thrown into the square collecting box through
centrifugal force to be collected in a centralized mode, the frequency of disassembling and assembling the filter screen plate is reduced, and more time is saved and more convenience is achieved.
