Abstract
The utility model relates to a workbench driving device, in particular to a rotation driving device of a numerical control machine workbench, which comprises drive motors. The driving device comprises two pairs of drive motors which are symmetrically arranged along the 180-degree direction of the workbench; the output of the drive motors adopts double-gear moment; and two gears in the drive motors are arranged in the manner of symmetric included angle. The workbench can stably rotate by the rotation driving device, the motor power is lowered, the driving effect is improved, and the service life of the machine tool is prolonged.
Description
Technical field
The utility model relates to a kind of Working table driving device, especially a kind of rotating driving device that is used for numerically controlled machine.
Background technology
At present, the platen rotation drives the main two kinds of forms that adopt, and a kind of is the worm and gear drive form, and another kind is the gear drive form.These two kinds of drive forms all are the modes that adopts one-sided driving, drive and are finished by a servomotor.But there is following defective in the version of one-sided driving: the first, and one-sided driving makes workbench one-sided stressed, causes being subjected to force unbalance in the workbench running work; The second, owing to realize driving by single servomotor, so motor requires motor to have bigger power will reach required driving torque the time; The 3rd, turntable gear or worm and gear synetion are subjected to higher torsional forces, need good radiating condition, and the gear or the worm couple that are used to simultaneously drive damage easily.
The utility model content
The purpose of this utility model has been to propose a kind of rotating driving device that is used for numerically controlled machine, and this device can make the workbench rotation steadily, reduces power of motor, improves to drive effect, and has prolonged the life-span of lathe.
The utility model is to adopt following technical scheme to realize: a kind of numerically controlled machine rotating driving device, this device comprises drive motors, wherein, this drive unit comprises two pairs of drive motors, and the two pairs of drive motors are symmetrical arranged along 180 ° of directions of workbench, drive motors adopts the output of bidentate wheel moment, and two gears in the drive motors are symmetrical angle setting.
The beneficial effects of the utility model are: the rotating driving device of workbench adopts the two versions of driving of four posts in the utility model, the drive motors that is about to the output of symmetrically arranged bidentate wheel replaces the existing one-sided high power drive motors that is arranged on, at first improved the balance of lathe, the workbench running steadily, do not have in the operation process and creep, guaranteed the balance of processing component simultaneously; The second, by two drive motors are set, reduce the power of drive motors, and improved the driving effect of motor; The 3rd, the temperature lift-off value when lathe drives reduces, and has improved machine tool accuracy, has prolonged the service life of Digit Control Machine Tool.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, in order to realize the rotation of numerically controlled machine 1, be symmetrical arranged two pairs of drive motors 2 in direction along 180 ° of workbench, drive motors 2 adopts the output of bidentate wheel moment, drive motors 2 links to each other with gear-box by shaft coupling, pass through gear 3 in the gear-box with on power distribution to two main drive gear, two gears 3 are symmetrical angle setting.Two pairs of bidentate wheels 3 make workbench 1 stress balance in the afterburning simultaneously driving of 180 ° horizontal symmetrical direction, have realized the disappear crack of workbench 1 in rotary course simultaneously, have guaranteed the stationarity of processing component; In addition, by two pairs of drive motors 2 are set, disperseed driving moment effectively, reduced the power and the moment of torsion of single drive motors, so drive motors 2 can adopt the low-power machine with smaller power and moment of torsion, improve the driving effect, the two technology of driving of other four posts can effectively reduce the temperature of the engaged transmission between driving and driven gear, reduce thermal deformation, improve driving force, make the higher or extra-high-speed type of original needs can not realize the output of the driving torque possibility that becomes.
