For the deficiencies in the prior art, the utility model provides a kind of drilling processing machine tool structure, and the utility model can lock fast to drill bit, has easy and simple to handle and feature efficiently.
The technical scheme solving the problems of the technologies described above is as follows:
Drilling processing machine tool structure, comprise base, bracing or strutting arrangement, drill bit device, motor and workpiece support, bracing or strutting arrangement is fixed on base, motor is fixed on bracing or strutting arrangement, the output shaft of motor is connected with drill bit device by chuck, workpiece support is fixed on the upper surface of base, drill bit device comprises drill body, the periphery of one end of drill body is the conical surface, the periphery of drill body is provided with spherical groove, also comprise a handle of a knife, this handle of a knife is provided with axial centre bore, the excircle of handle of a knife is provided with the radial hole that extends through described centre bore, this radial hole is stepped hole broad in the middle small in ends, an alignment pin and spring are slidably matched in radial hole, spring housing is on alignment pin, the inner ring of spring is fixedly connected with the periphery of alignment pin, the two ends of spring are spacing by two step surfaces of stepped hole respectively, described alignment pin is bulb towards the end of centre bore, after described drill body is inserted in centre bore, the bulb end of alignment pin is inserted in the spherical groove on drill body.
Adopt such scheme, because an end of drill body is the conical surface, while drill body being inserted in the through hole of handle of a knife, drill body squeezes alignment pin outward toward handle of a knife by the conical surface, for the cylindrical section of drill body is by out position, when the cylindrical section of drill body enters into after centre bore, along with the continuation of drill body is goed deep into, after conical end is arrived at the bottom of the hole of centre bore, rotary drill bit body, the bulb end of locating detent is snapped onto in the spherical groove on drill body, and like this, drill body is axially and circumferentially all locked.The utility model is simple to the lock mode of drill body, is inserted into rotary drilling-head body after centre bore by drill body.Have use simply, feature efficiently.After drill body is locked, electric machine rotation drives handle of a knife to rotate, and handle of a knife drives drill bit to rotate, then by bracing or strutting arrangement, drill bit device is imposed to axial feeding active force, can process the workpiece being arranged on workpiece assembling seat.
Bracing or strutting arrangement comprises guide pillar, support spring, lower supporting plate, upper backup pad and cylinder, guide pillar is fixed on base, support spring is enclosed within on guide pillar, lower supporting plate is slidably fitted on guide pillar, and support spring supports this lower supporting plate, and described motor is fixed on this lower supporting plate, upper backup pad is fixed on the upper end of guide pillar, cylinder is fixed on upper backup pad, and upper backup pad is provided with through hole, and the piston rod of cylinder is connected with lower supporting plate through after this through hole.When the utility model work, promoting lower supporting plate by cylinder moves downward, make drill bit carry out axial feed, thereby drill bit can add drilling processing to the workpiece being arranged on workpiece support, lower supporting plate moves downward in process, and compression support spring, after the active force of cylinder is withdrawn, support spring makes lower supporting plate reset under return action power, i.e. drive motor and drill bit return.The utility model is by the axial feed of cylinder control drill bit, and not only dynamics is even, and the speed of feeding is also that therefore, the quality of boring is ensured uniformly.Adopt in addition support spring that lower support is analysed and supported, after boring, cylinder return can make motor and drill bit self-return under elastic recovery active force, and without manual operation, automaticity is improved.
Also comprise the anvil piece that is fixed on base lower surface, described workpiece support is provided with stepped hole, and base is provided with resigning hole, and the resigning hole on stepped hole and base on workpiece support is interconnected.By stepped hole and resigning hole, not only contribute to discharge the metal that drilling produces and cut, and in the time drilling through hole, also contribute to step down for drill bit.
Bracing or strutting arrangement also comprises sleeve, and jacket casing is on spring, and the lower end of sleeve is supported on the upper surface of base.By the upper end of sleeve, can limit the range of lower supporting plate.
Also comprise a pull bar, this pull bar is connected with the other end of alignment pin.In the time that needs take out cutter body, by pull bar, overcome the active force of spring, alignment pin is exited from the spherical groove of cutter body, can remove like this locking of alignment pin to cutter body.
Described alignment pin is multiple, is at least arranged in two row, and each alignment pin listing is all connected with same pull bar.By such connected mode, once can remove the locking of the alignment pin being positioned on same position to cutter body.
