Description
Technical field
The utility model relates to the structure on a kind of numerically-controlled machine tool, servo motor on especially a kind of numerically controlled machine
The connection structure of main shaft.
Background technique
In the servo motor connection structure of numerically controlled machine, as shown in Fig.1 and Fig.2, servo motor 3 is mounted directly
Gear 4 drives transmission mechanism to realize speed change, in this mechanism, because servomotor spindle 30 is mounted directly gear 4, gear drive
In the process by the effect of radial force, this radial force is directly passed to servomotor spindle and main shaft bearing, leads to servo motor
Main shaft bearing abrasion is accelerated, after one period of work of numerical control machine, it may appear that following failure: first is that the noise of servo motor increases
Greatly, working environment is caused to become severe；Second is that servo motor rotor rubs with stator when serious, or even cannot normal work
Make, the service life of servo motor is caused to be substantially reduced.
Summary of the invention
In view of the above-mentioned problems, extending servo motor makes the purpose of this utility model is to provide a kind of reduction operating noise
With the servomotor spindle connection structure of the numerically controlled machine in service life.
The technical scheme adopted by the utility model is
The servomotor spindle connection structure of numerically controlled machine, the gear-box including installment work platform output shaft, work
Make platform output shaft to connect with the gear in gear-box, the servo lieed down is fixedly mounted by motor plate in the other side of gear-box
Motor, servomotor spindle engage connection with the driven wheel of gear by driving wheel, and the front end of servomotor spindle passes through
Expansion set is fixedly connected with driving wheel, and installation is connected with diameter axial bearing, diameter axial axis between the inner end and motor plate of driving wheel
The inner ring held is connect with driving wheel, and outer ring is connect with motor plate.
The beneficial effects of the utility model are: adding diameter axial bearing, diameter axial bearing is mounted on motor plate, and is supported
The front end of servomotor spindle, for servomotor spindle, since front end is additionally arranged diameter axial bearing, what driving wheel was subject to
Radial force passes to diameter axial bearing, is ultimately transferred to motor plate and cabinet, the radial direction that servomotor spindle internal bearings are born
Power greatly reduces, and in numerically-controlled machine tool use process, the servo motor noise ratio of control workbench work is substantially reduced before improving, and watches
The noise for taking motor is kept in normal range of operation, and the service life ratio of servo motor significantly improves before improving, the above two aspects effect
Fruit is obviously improved the quality of numerically-controlled machine tool and reliability.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is original numerically controlled machine servomotor spindle attachment structure schematic diagram one；
Fig. 2 is original numerically controlled machine servomotor spindle attachment structure schematic diagram two；
Fig. 3 is numerically controlled machine servomotor spindle attachment structure schematic diagram one after improving；
Fig. 4 is numerically controlled machine servomotor spindle attachment structure schematic diagram two after improving.
Specific embodiment
Referring to Fig. 3, Fig. 4, the servomotor spindle connection structure of the numerically controlled machine of the utility model, including installation
The gear-box 1 of workbench output shaft 100, workbench output shaft 50 are connect with the gear in gear-box 1, gear-box 1 it is another
The servo motor 3 lieed down is fixedly mounted by motor plate 2 in side, and the electric machine main shaft 30 of servo motor 3 passes through driving wheel 4 and speed change
The driven wheel 5 of mechanism engages connection, and the front end of servomotor spindle 30 is fixedly connected by expansion set 6 with driving wheel 4, routinely,
The outside of expansion set 6 is fixed by expansion set capping 60, and driven wheel 5 passes through other variable-speed motors such as worm screw expansion set 8, needle bearing 9, worm screw 10
Structure is connect with workbench output shaft 100.
The utility model is structurally characterized in that installation is connected with diameter axial axis between the inner end and motor plate 2 of driving wheel 4
7 are held, the inner ring 71 of diameter axial bearing 7 is connect with driving wheel 4, and outer ring 72 is connect with motor plate 2.
In addition, Conventional mechanisms in the present invention, no longer describe one by one.
In the present invention, i.e., in original gear cabinet 1, the structure of motor plate 2 is improved, adds the diameter axial axis
7 are held, diameter axial bearing 7 is mounted on motor plate 2, and carries the front end of servomotor spindle.To the main shaft 30 of servo motor 3
For, since front end is additionally arranged diameter axial bearing 7, the radial force that driving wheel 4 is subject to passes to diameter axial bearing 7, finally transmits
To motor plate 2 and cabinet 1；At the same time, the radial force that 30 internal bearings of servomotor spindle are born greatly reduces, hence it is evident that improves
The service life of servo motor.
Before improving relatively: first, in numerically-controlled machine tool use process, be substantially reduced before the noise ratio improvement of servo motor,
The noise of servo motor keeps being in normal range of operation, substantially improves working environment, and second, the service life ratio of servo motor changes
Into preceding significantly improving.The above two aspects effect is obviously improved the quality of numerically-controlled machine tool and reliability, further, the structure
It is particularly adapted to the numerically-controlled machine tool of cradle-type workbench.
Certainly, above embodiment is not unique restriction to the utility model, and other equivalent technical solutions should also be as
Within the protection scope of the invention.
