Abstract
The invention discloses a synchronous belt drive device for a milling head of a gear milling machine. The synchronous belt drive device comprises a main spindle box body, wherein a milling head box body is fixedly connected below the main spindle box body; a first synchronous wheel is fixedly connected above the milling head box body; a second synchronous wheel is fixedly connected below the milling head box body; the two synchronous wheels are connected and driven through a synchronous belt; a tool shaft is arranged in the middle of the first synchronous wheel; a drive shaft is arranged in the middle of the second synchronous wheel, and is used for driving the second synchronous wheel to rotate; and a tensioning device is arranged at an appropriate position on the milling head box body, and is used for keeping the synchronous belt in original tensioning state. Synchronous belt drive is adopted instead of the conventional gear drive, so that the synchronous belt drive device has the advantages: vibration of the drive shaft is reduced, the rotating speed of the shaft and the cutting accuracy of a milling tool are increased, the accuracy of a processed workpiece is increased, the product quality is improved by a grade, the service life of the entire milling head device including the milling tool is greatly prolonged, the economic benefit of an enterprise is increased stably, and the like.
Description
Technical field
The present invention relates to the simple and easy milling head device of numerical control gear milling lathe, belong to the Digit Control Machine Tool field.
Background technology
The knocking-over bar of the main processing textile machine tool of numerical control gear milling lathe is isometric to part, special a kind of mill teeth milling head that need be directed against lathe.The characteristics of such part are that tooth pitch is very little, and the blade of processing usefulness is very thin and can not use common vertebra shank type to clamp vertical processing, and blade needs laterally rotation.Need design a kind of milling head to this situation, change the transmission direction of main shaft, and guarantee machining accuracy.General this milling head mainly adopts gear drive, and main shaft directly drives the milling head rotation, and this mode strength is big; But blade is thin quick-fried broken easily; And spindle power is big, and generally milling this workpiece only needs the power about 1kw to get final product, the milling head of this mode to the processing blade of workpiece quick-fried when broken workpiece be prone to scrap; And the motor that uses is bigger, the cost of idleness and the energy.Thereby need a kind of milling head should guarantee crudy, can practice thrift the cost and the energy again.
Summary of the invention
In order to address the above problem, it is little to the invention provides a kind of power, saves the mill teeth machine milling head synchronous belt transmission device of the cost energy.
In order to achieve the above object, the present invention realizes through following technical scheme:
The present invention is a mill teeth machine milling head synchronous belt transmission device; Comprise the main shaft casing; Be fixedly connected a milling head casing at the main shaft lower box, be fixedly connected first synchronizing wheel, fixed connection second synchronizing wheel below the milling head casing on the top of milling head casing; Said two synchronizing wheels connect transmission through synchronous band.
Further improvement of the present invention is: in the centre of first synchronizing wheel one cutter shaft is set, is provided with power transmission shaft in the centre of second synchronizing wheel, drive second synchronizing wheel and rotate.One swelling device is set on the milling head casing, guarantees that band is in original tensioner state synchronously.
Beneficial effect of the present invention is: replaced traditional gear drive with band transmission synchronously; Reduce the vibrations of power transmission shaft; Improve the rotating speed and the cutting accuracy of milling cutter of axle, make the workpiece accuracy lifting of processing, on the product quality a new step; And prolonged the service life that whole milling head device comprises milling cutter greatly, made advantages such as economic benefit of enterprises steadily improves.
Power of the present invention is little, saves the cost and the energy, is not prone to the quick-fried broken of blade, has guaranteed the precision of workpiece and the stability of processing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
As shown in Figure 1, the present invention is a mill teeth machine milling head synchronous belt transmission device, comprises main shaft casing 1; Below said main shaft casing 1, be fixedly connected a milling head casing 2, be fixedly connected first synchronizing wheel 5, be fixedly connected second synchronizing wheel 8 in the bottom of said milling head casing 2 on the top of said milling head casing 2; Said first synchronizing wheel 5 and second synchronizing wheel 8 are through be with 6 to be connected transmission synchronously; In the centre of said first synchronizing wheel 5 cutter shaft 4 is set, is provided with power transmission shaft 7, drive said second synchronizing wheel 8 and rotate in the centre of said second synchronizing wheel 8; Saidly drive synchronously the rotation that drives cutter shaft 4 with 6 through synchronizing wheel 5 by power transmission shaft 7; On said milling head casing 2,, guarantee saidly to be with 6 to be in original tensioner state synchronously band generation stretcher strain under the effect of pulling force synchronously with the fixing swelling device 3 of screw; And the dilatation that causes under the temperature action, guaranteeing has certain moderate tension between drive unit to the tensioner dress.
Structural member of the present invention has changed old-fashioned gear drive, the synchronizing wheel stable drive, and the damage of blade is little, and synchronizing wheel adopts the tensioner fixed form with axle, and axle is held tightly mutually with the hole, avoids key and pin drive gap, reaches best transmission effect.
