The utility model provides a technical scheme that its technical problem adopted is: the adjustable inner-cooling deep-hole boring bar is provided with a hollow boring bar, an end cover is fixed at the front end of the boring bar, a tool apron capable of moving and adjusting along the radial direction of the boring bar is arranged on the end cover, a turning tool capable of adjusting along the radial direction is installed on the tool apron, a tailstock capable of moving on a machine tool guide rail when in use is arranged at the rear end of the boring bar, a positioning sleeve supported by a machine tool center frame when in use is sleeved on the boring bar, a water pipe joint capable of introducing external cooling water is installed on the rear end face of the boring bar, and a water pipe connected with the water pipe joint in the boring bar is communicated.
Specifically, the tool apron is provided with a radial long hole, and the tool apron is adjustably arranged on the end cover by screwing a tool apron bolt into a screw hole on the end cover; the turning tool is provided with a radial long hole, and the turning tool is adjustably installed on the tool apron through a screw hole formed by screwing a tool pressing bolt into the tool apron.
Furthermore, the tailstock is provided with two support frames which are arranged side by side, the rear end of the boring rod penetrates through the support frames, and adjustable press covers which can meet the use requirements of boring rods with different diameters are respectively arranged on two sides of each support frame.
The utility model has the advantages that: the utility model discloses a but the blade holder of radial movement regulation adopts the lathe tool structure of adjustable installation simultaneously, has enlarged the bore diameter scope of boring, leads to water cooling machined surface through the boring bar is inside to the lathe tool, has reduced the lathe tool wearing and tearing, and the whole rigidity of boring row is good, just can use at the lathe, has practiced thrift manufacturing cost, is favorable to improving the precision and the roughness of machining efficiency and bore hole.
