Abstract
The utility model relates to the technical field of manufacture of processing machinery, in particular to a screw driving structure for rotating nuts. The screw driving structure for rotating nuts comprises a screw, bases, a screw nut, a servo motor and a driving component, the bases are arranged at two ends of the screw and used for fixing the screw, the screw nut is matched with the screw, and the servo motor drives the screw to rotate. The screw driving structure is characterized in that the driving component comprises a screw bearing, a bearing seat, a servo motor belt pulley, a nut belt pulley and a driving belt, the screw bearing is mounted in the bearing seat, the bearing seat is fixedly connected with the screw nut through the nut belt pulley, the servo motor belt pulley is arranged at an output end of the servo motor, and the servo motor belt pulley and the nut belt pulley are connected through the driving belt. When the screw driving structure for the rotating nuts operates, the servo motor moves along with the screw nut, and decrease of driving thrust consumption caused by a too long ball screw is avoided.
Description
Technical field
The utility model relates to working machine manufacturing technology field, particularly a kind of screw rod transmission structure of rotating nut.
Background technique
Employing screw mandrels a large amount of in existing lathe are as transmission device, and this kind spindle gear is provided with on bearing support, screw mandrel at screw mandrel two ends and is provided with slide block, and during lathe work, screw mandrel drives the screw mandrel rotation by driving actuating motor, and the band movable slider is along the screw mandrel axial-movement.When screw mandrel length was longer, the transmission thrust of actuating motor diminished, easily causes the screw mandrel pogo stick, affects machining accuracy.
The model utility content
in order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of screw rod transmission structure of rotating nut, comprise screw mandrel, be located at screw mandrel two ends and be used for the fixedly pedestal of screw mandrel, with the suitable feed screw nut of screw mandrel, drive actuating motor and the transmitting assemblies of screw mandrel rotation, it is characterized in that: described transmitting assemblies comprises the screw mandrel bearing, bearing support, actuating motor end belt pulley, nut end belt pulley and drivign belt, described screw mandrel bearing is installed in bearing support, bearing support is fixedly connected with the feed screw nut by the nut end belt pulley, actuating motor end belt pulley is arranged at the output terminal of actuating motor, actuating motor end belt pulley is connected by drivign belt with the nut end belt pulley.
Further, described screw mandrel bearing is the thrust angular contact bearing.
Further, described screw mandrel is ball screw.
Further, described bearing support and nut end belt pulley are bolted, and nut end belt pulley and feed screw nut are bolted.
Actuating motor by motor fixing seat be fixed on moving element, bearing support is fixedly connected with moving element.During work, actuating motor drives the nut end belt pulley to drive feed screw nut's rotation by actuating motor end belt pulley, and the feed screw nut moves thereby promote moving element according to the screw mandrel orbiting.
The beneficial effects of the utility model are as follows:
The screw rod transmission structure of the rotating nut that the utility model provides is fixed in screw mandrel on pedestal, and servo drive motor and transmitting assemblies are fixed on moving element, and actuating motor is connected with transmitting assemblies and drives feed screw nut rotation; During work, the feed screw nut moves on screw mandrel, drives simultaneously moving element and the servo drive motor and the bearing support that are fixed on moving element move together; In transmission process, actuating motor and transmitting assemblies are followed the feed screw nut and are moved, and avoid causing because screw mandrel is long the thrust consumption of transmission to diminish.

Fig. 2 is the structural representation of the utility model embodiment transmitting assemblies.
Fig. 3 is the schematic diagram of the screw rod transmission structure of the utility model embodiment rotating nut.
Embodiment
In order better to understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail.
With reference to Fig. 1, shown in Figure 2, a kind of screw rod transmission structure of rotating nut comprises screw mandrel 1, pedestal 2, feed screw nut 3, actuating motor 4, transmitting assemblies 5.Screw mandrel 1 is ball screw, and its two ends are individually fixed on pedestal 2; Feed screw nut 3 is installed on screw mandrel 1 and is suitable with it; Actuating motor 4 is connected with transmitting assemblies 5, and drives feed screw nut's 3 rotations.
Transmitting assemblies 5 comprises screw mandrel bearing 51, bearing support 52, actuating motor end belt pulley 53, nut end belt pulley 54 and drivign belt 55.Screw mandrel bearing 51 is the thrust angular contact bearing, and it is installed on bearing support 52 inner support screw mandrel 1 rotations; Bearing support 52 is connected by bolt 541 with nut end belt pulley 54, and nut end belt pulley 54 is connected by bolt 542 with feed screw nut 3; Actuating motor end belt pulley 53 is arranged at the output terminal of actuating motor 4, and actuating motor end belt pulley 53 is connected by drivign belt 55 with nut end belt pulley 54.
With reference to shown in Figure 3.The working condition of the ball leading screw driving structure of this kind rotating nut is as follows:
With actuating motor 4 by motor fixing seat be fixed on moving element 10, bearing support 52 is fixedly connected with moving element 10.During work, actuating motor 4 drives nut end belt pulley 54 to drive feed screw nut's 3 rotations by actuating motor end belt pulley 53, and feed screw nut 3 moves thereby promote moving element 10 according to screw mandrel 1 orbiting.In transmission process, actuating motor 4 moves together with transmitting assemblies 5 is followed feed screw nut 3, avoids causing because screw mandrel 1 is long the thrust consumption of transmission to diminish.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
