Detailed description of the invention
Below in conjunction with the accompanying drawing in the present embodiment, carry out specifically, clearly and completely describing to the technical scheme in embodiment.
Shown in Figure 1, the graphite material deep and long hole processing unit (plant) of the present embodiment, be fixedly connected with integral with drilling machine, it comprises: drill bit assembly, detent mechanism 2 and detent bracket 1.
Shown in Fig. 2 and Fig. 3, described detent mechanism 2 is arranged on detent bracket 1, and near an end of graphite workpiece 6, described detent mechanism 2 comprises a locating rack 21, described locating rack 21 is fixedly installed a spitting drill bushing 22, both are fixedly connected with by least one set bolt 23, and preferably, set bolt 23 is provided with three.
Described drill bit assembly comprises: one first drill bit, at least in order to be fixedly connected with drilling machine, before boring, spitting drill bushing 22 gets out a spitting drill bushing hole 22a;
One is identical with the first bit diameter, and length is greater than the second drill bit 32 of the first drill bit, at least in order to replace the first drill bit when holing, front end is all the time through described spitting drill trepanning 22a, and freely can retreat along boring direction in spitting drill trepanning, the constraint in direction up and down by spitting drill bushing 22 can not move deflection.
Described drilling machine is provided with drill press spindle 4, described drill press spindle 4 is provided with drill chuck 5, described first drill bit or the second drill bit 32 are fixedly connected with drill chuck 5.Described drilling machine is fixedly connected with one end away from graphite workpiece 8 of detent bracket 1.
On drill chuck of drilling machine 5, first load onto one before using with processing aperture with the first drill bit of diameter, spitting drill bushing 22 gets out spitting drill trepanning 22a, and spitting drill trepanning 22a and drill press spindle 4 have good concentricity to adopt this method to ensure; Then change the outfit the front end of the second drill bit 32, second drill bit 32 of processing graphite through the aforementioned spitting drill trepanning 22a processed, between locating rack 21 and graphite workpiece 6, keep suitable gap.
