Numerical control drilling all-in-one
The utility model relates to numerical control drilling field, particularly numerical control drilling all-in-one.
Now be fixed on the load fixed head of elevating mechanism with the drill unit on numerical control drilling all-in-one, the sliding bar that load fixed head the both sides slip ring fixed and the two ends be up and down located in slip ring are fixed on slide plate is connected, the feed screw nut and the leading screw that are fixed on load fixed head centre are spirally connected, leading screw upper end is connected with the drive motors be fixed on slide plate, and this drive motors is by leading screw, the oscilaltion of feed screw nut band dynamic load fixed head; Crossbeam on slide plate and numerical control drilling machine is slidably connected, and drives slide plate to move left and right on crossbeam by another motor be fixed on slide plate.Because load fixed head is connected with sliding bar by slip ring, slide bar two ends are fixed on slide plate, when in boring procedure, due to the impact by cutting arrangement load, especially when cutting arrangement load is excessive, easily make slide bar mid portion arch upward laterally and be out of shape, be directed at slip ring and run not smooth on slide bar, while affecting process velocity, also have impact on machining accuracy.
Summary of the invention
The utility model solve technical problem be to provide a kind of numerical control drilling all-in-one improving machining accuracy, meet load request.
Technical solutions of the utility model complete like this, numerical control drilling all-in-one, include elevating mechanism, described elevating mechanism is provided with load fixed head, slide plate, leading screw, leading screw drive motors, load fixed head and slide plate slides link together, the nut matched with leading screw is fixed with in the middle of load fixed head, nut and leading screw are screwed together, leading screw and leading screw drive motors are rotationally connected, load fixed head two ends are fixed together with the slide block being provided with dovetail groove, the slide block being provided with dovetail groove be fixed on together with being slidably connected with the line slideway that the slide block being provided with dovetail groove matches on slide plate.
Further preferred embodiment, leading screw is rotationally connected by plum coupling and leading screw drive motors.
Technique effect of the present utility model is, because load fixed head is by being provided with the slide block of dovetail groove together with being fixed on the line slideway on slide plate and being slidably connected, line slideway and slide block are the contact in face and face all the time, line slideway is also the contact in face and face all the time with slide plate, fully ensure that load fixed head has enough bearing capacities, make load fixed head operationally more stable, substantially increase drilling precision.
