At present, drilling machine drilling large diameter hole need to carry out step by step, first gets out small diameter bore that is:, then carries out reaming, in this process, needs to change cutter, cause working (machining) efficiency low, and roughness is of poor quality, is generally Ra25.As guaranteed the crudy in hole, need to carry out boring machine bore hole, processing cost will increase substantially, and working (machining) efficiency further reduces.
Summary of the invention
Technical problem to be solved by this invention is: a kind of drilling machine composite drill is provided, and on drilling machine, once property gets out diameter through hole, improves working (machining) efficiency, and guarantees drilling quality.
For solving the problems of the technologies described above, technical scheme of the present invention is: drilling machine composite drill, comprise composite drill body, described composite drill body comprises connection handle, drilling rod and drill bit, described connection handle connects the main shaft interface of drilling machine, is set with cooling fluid slip ring on described connection handle, and described drilling rod one end connects described connection handle, the other end connects described drill bit, and described drill bit comprises the centre drill for holing and is arranged on the blade for reaming of described centre drill top; Described composite drill body interior is provided with the cooling fluid hole for guaranteeing described bit cutting performance, described cooling fluid hole comprises the first cooling fluid hole and the second cooling fluid hole, described first one end, cooling fluid hole is communicated with described cooling fluid slip ring, the other end extends to described centre drill after running through described drilling rod, described second one end, cooling fluid hole is communicated with described the first cooling fluid hole, and the other end extends to described blade.
As one, improve, described blade is clip type blade.
Adopted after technique scheme, the invention has the beneficial effects as follows: because drilling machine composite drill comprises composite drill body, described composite drill body comprises connection handle, drilling rod and drill bit, described connection handle connects the main shaft interface of drilling machine, on described connection handle, be set with cooling fluid slip ring, described drilling rod one end connects described connection handle, and the other end connects described drill bit, and described drill bit comprises centre drill and blade; Described composite drill body interior is provided with cooling fluid hole, make drill bit integrated brill small diameter bore and hole expansion function, thereby get out small diameter bore by centre drill, then by blade, carry out reaming, on drilling machine, once property gets out diameter through hole; With use that drilling machine substep is holed, compared with reaming, working (machining) efficiency improves 4 times of left and right, and crudy is high; Compared with using boring machine bore hole after using drilling machine boring, working (machining) efficiency improves 8 times of left and right, and processing cost reduces greatly.Drilling machine composite drill provided by the invention has improved working (machining) efficiency greatly, and guarantees drilling quality, and roughness reaches Ra6.3～Ra3.2, and aperture precision is H11 accuracy class.
Because described cooling fluid hole comprises the first cooling fluid hole and the second cooling fluid hole, described first one end, cooling fluid hole is communicated with described cooling fluid slip ring, the other end extends to described centre drill after running through described drilling rod, described second one end, cooling fluid hole is communicated with described the first cooling fluid hole, and the other end extends to described blade; Add man-hour, high-pressure coolant enters the first cooling fluid hole by cooling fluid slip ring, then by the first cooling fluid hole and the second cooling fluid hole, and powerful cooling drill bit, the cutting ability of assurance drill bit; And iron filings, under high-pressure coolant effect, are discharged in time, have greatly improved stock-removing efficiency.
Because described blade is clip type blade, clip type blade is without high-temperature soldering, and the blade hardness that can avoid causing because of high-temperature soldering declines and the defect such as cracks, and has improved blade life; Clip type blade guarantees higher resetting installation accuracy by locating surface is installed, and effectively guarantees installation accuracy and the tool changing efficiency of blade; Clip type blade, by special anterior angle and relief angle design, guarantees cutting precision and durability; By selecting suitable blade material, to adapt to, to solve the problem of drilling machine poor rigidity, and control good chip breaking length, to guarantee that high-pressure coolant can discharge iron filings smoothly.
