Abstract
The utility model discloses a numerical control machine tool driving mechanism. The driving mechanism is positioned in a groove of a machine tool body and under a machine tool column; in the driving mechanism, each servomotor is provided with a precision reductor to drive a gear and a rack at the tail end of a transmission chain to be meshed with each other, so that the column can accomplish feed movement with a defined function. Synchronization of the servomotors is adjusted by an electrical system, so that kinematic accuracy of a machine tool can be ensured, the mounting process is simplified, and the efficiency is improved.
Description
Technical field
The utility model relates to Digit Control Machine Tool field, especially a kind of driving mechanism of numerical control machine feed movement.
Background technology
As depicted in figs. 1 and 2, the column 8 of cnc boring and milling machine needs often along the direction of determining, X-direction coordinate direction in figure moves, the mechanism that driving column 8 moves is arranged in gear-box 10, in present cnc boring and milling machine, this driving mechanism is double-rack-and-pinion mechanism, and present gear 5 and gear 6 are to drive Double- gears 5 and 6 by a servomotor 1 by multi-stage speed-reducing system 11 to complete the feed motion of X coordinate direction with tooth bar 7 engagement drive columns 8.The gear-box volume of this structure is larger, and processing and install very difficultly and due to large by multi-stage gear reduction of speed back lash, is difficult to guarantee the positioning accuracy request of Digit Control Machine Tool.
Summary of the invention
For structural deficiency in prior art, the purpose of this utility model is to provide a kind of Digit Control Machine Tool driving mechanism, with the simplification installation process, and the positioning accuracy of assurance lathe.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of Digit Control Machine Tool driving mechanism, and this driving mechanism is positioned in the bed piece groove, under machine pillar, comprise two servomotors, each servomotor respectively drives a gear output by a precision speed reduction device.
Each servomotor drives the wheel and rack engagement of driving-chain end by a precision speed reduction device in practical operation, completes the feed motion of directions.Two servomotors are synchronous by the adjustment realization of electrical system, thereby guaranteed being synchronized with the movement of two gears, and then guaranteed the kinematic accuracy of lathe.
The beneficial effects of the utility model are to adopt this driving mechanism, have not only guaranteed the positioning accuracy of lathe, and have simplified mounting process, have alleviated workman's labour intensity, have improved production efficiency.
Description of drawings
Fig. 1 is the single motor Double-gear driving mechanism before improving.
Fig. 2 is the detail view of the single motor Double-gear driving mechanism before improving.
Fig. 3 is dual-motor driving mechanism of the present utility model.
Fig. 4 is the detail view of dual-motor driving mechanism of the present utility model.
The specific embodiment
Reaching by reference to the accompanying drawings embodiment is illustrated Digit Control Machine Tool driving mechanism of the present utility model.
As shown in Figure 3 and Figure 4, Digit Control Machine Tool driving mechanism of the present utility model comprises servomotor 1 and 2, the precision speed reduction device 3 and 4 that is connected with servomotor, by precision speed reduction device by the gear 5 and 6 of driven by servomotor, with the tooth bar 7 of gear engagement, servomotor 1,2, precision speed reduction device 3,4, gear 5,6 and tooth bar 7 be arranged in gear- box 10,10 of gear-boxes are arranged in the groove of machine base body 9, are positioned at the below of column 8.Servomotor 1,2 meshes with tooth bar 7 by precision speed reduction device 3,4 driven wheels 5,6, makes column 8 complete the feed motion of X-direction coordinate.Servomotor 1 and 2 is adjusted into synchronously by other electrical system, so both can guarantee the machine tool motion precision, and simplify mounting process, has alleviated labour intensity, has improved efficient.
