Abstract

The utility model relates to a kind of gantry unit head drive unit.Comprise servomotor (1), servomotor (1) drives screw mandrel (3) to move up and down by belt pulley (2), the guide rail (4) that the upper connection one of screw mandrel (3) moves up and down in company with screw mandrel (3), guide rail (4) connects unit head (5) to be made it to move up and down with guide rail (4); Also be provided with spindle motor (6), spindle motor (6) drives unit head (5) to rotate by gear-box (7).The utility model drives the mechanism that moves up and down of unit head to be realized by the transmission of screw mandrel, and screw mandrel has that precision is high, the advantage of smooth running, and therefore driving head moves up and down steadily; Its two the utility model drives unit head to rotate by gear-box, utilizes that gear box ratio is large, the feature of smooth running; Therefore the utility model is according to the needs of unit head two kinds of different motion forms, have selected corresponding drive transmission device, achieves accurate, the stable requirement of gas.

Description

A kind of gantry unit head drive unit
Technical field
The utility model relates to a kind of gantry unit head drive unit, belongs to technical field of driving.
Background technology
Gantry unit head operationally, needs the motion in both direction, the first vertically on moving up and down, it two is rotary motions of horizontal direction; Because need the different drive system of two covers to realize, therefore higher requirement is proposed in the stationarity of the compactness in transmission accuracy, total and motion, existing drive unit well can not take into account each requirement above, thus needs to be improved further.
Utility model content
The utility model is for above-mentioned defect, and it is high that object is to provide a kind of smooth running, precision, and a kind of gantry unit head drive unit of compact conformation.
The technical solution adopted in the utility model is for this reason: the utility model comprises servomotor (1), servomotor (1) drives screw mandrel (3) to move up and down by belt pulley (2), the guide rail (4) that the upper connection one of screw mandrel (3) moves up and down in company with screw mandrel (3), guide rail (4) connects unit head (5) to be made it to move up and down with guide rail (4);
Also be provided with spindle motor (6), spindle motor (6) drives unit head (5) to rotate by gear-box (7).
Described guide rail (4) and gear-box (7) point are located at the both sides of unit head (5).
Described guide rail (4) is arranged in frame (8), and the form by sliding between guide rail (4) and frame (8) coordinates.
The utility model has the advantages that: 1) the utility model drives the mechanism that moves up and down of unit head to be realized by the transmission of screw mandrel, screw mandrel has that precision is high, the advantage of smooth running, and therefore driving head moves up and down steadily; Its two the utility model drives unit head to rotate by gear-box, utilizes that gear box ratio is large, the feature of smooth running; Therefore the utility model is according to the needs of unit head two kinds of different motion forms, have selected corresponding drive transmission device, achieves accurate, the stable requirement of gas;
2) guide rail and gear-box are divided the both sides being located at unit head by the utility model, and both heteropleurals are arranged, and therefore facilitate the arrangement that two covers drive transmission; Compare the set-up mode of side simultaneously, its layout of mode that heteropleural is arranged is more reasonable, also make the stressed more reasonable of whole mechanism, prevent the overweight distortion etc. causing mechanism after longtime running in side, therefore the utility model has higher service life, better stability;
3) the utility model is in order to improve the stability of motion further, guide rail of the present utility model and frame are coordinated by the form of sliding, because frame is stationarity, it is not vulnerable to the impact of the extraneous factors such as vibration, therefore the version that restricted by frame of guide rail, guide rail can be made to move up and down more straight, can not cause bending situation after long-term motion, therefore that driving head can be made to operate up and down is more steady for structure of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be servomotor, 2 be belt pulley in figure, 3 be screw mandrel, 4 be guide rail, 5 be unit head, 6 be spindle motor, 7 be gear-box, 8 for frame.
Detailed description of the invention
The utility model comprises servomotor 1, and servomotor 1 drives screw mandrel 3 to move up and down by belt pulley 2, and screw mandrel 3 connects a guide rail 4 moved up and down in company with screw mandrel 3, guide rail 4 connects unit head 5 to be made it to move up and down with guide rail 4;
Also be provided with spindle motor 6, spindle motor 6 drives unit head 5 to rotate by gear-box 7.
Described guide rail 4 and gear-box 7 points are located at the both sides of unit head 5.
Described guide rail 4 is arranged in frame 8, and the form by sliding between guide rail 4 and frame 8 coordinates.
The course of work of the present utility model is: first rotated by servomotor 1 drive pulley 2, then drive guide rail 4 to move up and down by screw mandrel 3, thus unit head 5 is moved up and down, until unit head 5 after vertical direction motion puts in place; Stop servomotor 1, then drives spindle motor 6, and then drive unit head 5 to rotate by gear-box 7.

Claims (1)
