Once the working environment of the rotor system changes, the support needs to be replaced as a whole, which is troublesome to operate and will affect the processing cost.

[0003] Therefore, a multi-directional adjustment support based on gear transmission is designed. This support can realize the multi-directional adjustment of rotor system parts in the horizontal and vertical directions to meet the requirements of different working conditions. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model designs a multi-directional adjustment support based on gear transmission, including: upper support plate, lower support plate, upper support, lower support, slide rail, rack, gear, servo motor, long shaft, short shaft, coupling sleeve, bearing, bearing support block and motor mounting bracket, characterized in that: the lower support and the motor mounting bracket are welded on the lower support plate, the upper support is sleeved inside the lower support, there are two racks, one is fixed on the inner wall of the upper support and meshes with the first gear, the other is fixed on the bottom of the upper support plate and meshes with the second gear, there are two servo motors, one is connected to the long shaft, and the other is connected to the short shaft, the first gear passes through the long shaft and is fixed to the shaft by welding, the second gear passes through the short shaft and is fixed to the shaft by welding, the bearing is sleeved on the shaft and installed on the bearing support block, the screw is installed on the bearing support block to fix the bearing support block on both sides of the support, the slide rail consists of upper and lower parts, the upper part of the slide rail is welded to the bottom of the upper support plate, and the lower part of the slide rail is welded to the top of the upper support, and the servo motor is connected to the shaft through the coupling sleeve.

[0006] As a further improvement of the above solution, a clearance fit is adopted between the upper support and the lower support, a rack is welded on the inner wall of the upper support, the first gear passes through the long shaft and is fixed to the shaft, the long shaft passes through the lower support and is fixed to the lower support, the first gear meshes with the rack, and the movement of the rack welded on the inner wall of the upper support is driven by the rotation of the first gear to realize the vertical movement of the upper support.

[0007] As a further improvement of the above solution, through holes are opened in the middle of the first gear and the second gear, and the shaft passes through the through holes of the gears and is welded together.

[0008] As a further improvement of the above solution, the bearing is mounted on the shaft and fixed by a shaft shoulder and a bearing support block.

[0009] As a further improvement of the above solution, a hole with the same size as the outer ring of the bearing is opened in the middle of the bearing support block and can fix the position of the outer ring of the bearing. A through hole is opened on the bearing support block for installing screws. The bearing support block is installed on both sides of the support by screws.

The set screw passes through the hole on the coupling bushing to fix the flat key, thus ensuring the smooth output of power.

[0014] As a further improvement of the above solution, the servo motor has a function of locking the shaft. When the motor stops moving, the motor shaft is in a locked state, and the gears on the shaft and the related racks will also be in a locked state, thus ensuring the stability of the entire multi-directional adjustment support in the non-working state and preventing accidental sliding or rotation.

[0015] As a further improvement of the above solution, the motor mounting bracket is fixed to the lower support plate by welding. There are four bolt holes and one shaft hole on the motor mounting bracket. The servo motor is installed on the motor mounting bracket with four bolts.

[0016] As a further improvement of the above solution, due to its light weight, the servo motor can be directly suspended.

[0017] Compared with the prior art, the utility model provides a multi-directional adjustable support based on gear transmission. By controlling the servo motor, the rotation of the first gear on the long axis can be controlled to achieve precise adjustment of the vertical position of the upper support, and then the vertical position of the upper support plate can be adjusted in linkage; at the same time, the servo motor is controlled to rotate the second gear on the short axis, thereby adjusting the lateral position of the upper support plate. The design of the overall mechanism not only improves the flexibility and accuracy of the adjustment, but also enhances the stability of the support system and the convenience of operation. It is suitable for occasions that require fine adjustment in multiple directions. BRIEF DESCRIPTION OF THE DRAWINGS

There are two servo motors 9, one is connected to the long shaft 10 and the other is connected to the short shaft 11. The first gear 7 passes through the long shaft 10 and is fixed to the shaft by welding. The second gear 8 passes through the short shaft 11 and is fixed to the shaft by welding. The bearing 13 is sleeved on the shaft and installed on the bearing support block 14. Screws are installed on the bearing support block 14 to fix the bearing support block 14 on both sides of the support. The slide rail 5 is composed of upper and lower parts. The upper part of the slide rail 5-1 is welded to the bottom of the upper support plate 1, and the lower part of the slide rail 5-2 is welded to the top of the upper support 3. The servo motor 9 is connected to the shaft through the coupling sleeve 12.

[0025] A clearance fit is adopted between the upper support 3 and the lower support 4. A rack 6 is welded to the inner wall of the upper support 3. The first gear 7 passes through the long shaft 10 and is fixed to the shaft. The long shaft 10 passes through the lower support 4 and is fixed to the lower support 4. The first gear 7 meshes with the rack 6. By rotating the first gear 7, the rack 6 welded to the inner wall of the upper support 3 moves, realizing the vertical movement of the upper support 3.

[0026] Through holes are opened in the middle of the first gear 7 and the second gear 8. The shaft passes through the through holes of the gears and is welded together.

[0027] The bearing 13 is installed on the shaft, and the bearing 13 is fixed by the shaft shoulder and the bearing support block 14.

[0028] A hole with the same size as the outer ring of the bearing 13 is opened in the middle of the bearing support block 14 and can fix the position of the outer ring of the bearing 13.
