A kind of drilling tapping machineTechnical field
The utility model relates to a kind of machining equipment, relates in particular to a kind of drilling tapping machine.
Background technology
At present some equipment apertures and position accuracy demand are high only has dead eye, gear level hole and assembling dowel hole, and quantity is few; And quantity many be via hole and screwed hole, specification is more, existing through hole has again blind hole, number of cutters is many, therefore tool change time is long, and it is short that via hole and screwed hole part machine add less demanding, pure machining time, if still processing in turn seriously restricts the performance of production efficiency and costly machining center economy.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide a kind of above problem that solved, by not tight via hole and the screwed hole of required precision, machining content is decomposed out from being worth higher machining center, the drilling tapping machine of processing simultaneously and rapidly.
The technical solution of the utility model is: a kind of drilling tapping machine, comprise feeding synchronized, also comprise base plate and end plate, on described base plate, be vertically provided with slide bar, described end plate is provided with the slide opening matching with slide bar, and described end plate is slidably connected by slide bar and base plate, described feeding synchronized is positioned at end plate center, and be fixedly connected with end plate, be connected with the lowering or hoisting gear that regulates its height on described feeding synchronized, described plate upper surface is provided with the fixture block of restriction workpiece movable;
As preferably, described feeding synchronized bottom is connected with a plurality of cutters, offers the tool assembly hole matching with cutter on described end plate;
As preferably, described feeding synchronized comprises servomotor, motor shaft, synchronizing wheel, pitch gear, reduction gearing and cutter holding instrument.
The beneficial effects of the utility model are: the utility model stable connection simple in structure, after compressing, workpiece is difficult for moving, easy to process, and has adopted feeding synchronized, to the not high via hole of some required precisions and screwed hole synchronous processing, greatly improved production efficiency.

The specific embodiment
Embodiment: as a kind of embodiment of the present utility model, a kind of drilling tapping machine as shown in Figure 1, comprise feeding synchronized 1, also comprise base plate 3 and end plate 2, on described base plate, be vertically provided with slide bar 4, described end plate 2 is provided with the slide opening matching with slide bar 4, described end plate 2 is slidably connected by slide bar 4 and base plate 3, by lowering or hoisting gear 5, drive end plate 2 to move up and down, compressed punching tapping work, described feeding synchronized 1 is positioned at end plate 2 centers, and be fixedly connected with end plate 2, on described feeding synchronized 1, be connected with the lowering or hoisting gear 5 that regulates its height, described base plate 3 upper surfaces are provided with the fixture block 7 of restriction workpiece movable, its clamping workpiece is avoided its effect of moving, described feeding synchronized 1 bottom is connected with a plurality of cutters 6, on described end plate 2, offer the tool assembly hole matching with cutter 6, each cutter 6 is realized synchronous rotation by feeding synchronized 1, accelerate working (machining) efficiency.
Described feeding synchronized 1 comprises servomotor, motor shaft, synchronizing wheel, pitch gear, reduction gearing and cutter holding instrument, servomotor drive motor axle rotates, motor shaft drives synchronizing wheel more successively, pitch gear, reduction gearing, by the same rotating speed of motor shaft input, by feeding synchronized 1 speed change, with same feed value, export the torque of the required different rotating speeds in product particular bore position and machining need to, the final cutter holding instrument that drives, realize the synchronous rotation of cutter 6, realization is to the not high via hole of some required precisions and screwed hole synchronous processing, greatly improved production efficiency.
