Description
Technical field
The invention belongs to field of mechanical technique, relate to the rotary table transmission device of a kind of numerical control drilling machine, particularly a kind of numerical control drilling machine.
Background technology
At present, drilling machine be used for to workpiece hole, a kind of machine of processing such as tapping.Drilling machine is used widely in mechanical field at present, and the processing of disk-like accessory circumferential apertures generally has three kinds of methods, and the one, during single-piece production, line boring on part, the 2nd, during many variety production of small lot, make drill jig boring; The 3rd, when lacking variety production in enormous quantities, manufacture the boring of multiaxis main spindle box special purpose machine tool.
These several production technologies respectively have pluses and minuses, though line boring can solve the problem of single-piece production, its efficient and precision are all relatively poor; The boring of making drill jig adapt to the many variety production of small batch, but the bore position degree is relatively poor, should not guarantee higher positional precision; Multiaxis main spindle box special purpose machine tool boring is fit to single specification production in enormous quantities, and production efficiency and bore position precision are all more satisfactory, but can not the conversion description, the incompatibility Multi-varieties and Small-batch Production.When the hole in the single-piece work irregular alignment particularly, production efficiency is very low, can't produce in batches.Enhance productivity, this need buy equipment such as machining center, when because cost is very high, can't be adapted to the processing of domestic consumer.
Therefore, people design various numerical control drilling machines, in numerical control drilling machine, the rotating disk that wherein carries disc type work is a key component, rotating disk drives workpiece and forwards behind the preposition location to and disc type work is holed, have only the position of disc type work location accurately just can process high-quality product, existing numerical control drilling machine then can't accomplish exactly the location of disc type work, causes rotating disk poor location, the borehole accuracy of common numerical control drilling machine low etc.
Summary of the invention
The objective of the invention is to have above-mentioned problem, the rotary table transmission device of the numerical control drilling machine of a kind of precision height, stable, rotating disk good positioning effect is provided at the rotary table transmission device of existing numerical control drilling machine.
Purpose of the present invention can realize by following technical proposal: a kind of rotary table transmission device of numerical control drilling machine, be arranged on the support of numerical control drilling machine, comprise and be arranged on rotating disk that is used for the clamping disc type work on the support and the motor that drives dial rotation, it is characterized in that, between rotating disk and motor, be provided with the Worm and worm-wheel gearing that drives dial rotation, worm screw suppressed the detent mechanism that prevents dial rotation during in boring being provided with one on the support.
