[0026] Please refer to Figure 1-Figure 2 , Figure 1 A schematic structural diagram of an embodiment of the present utility model, Figure 2 A schematic structural diagram of another angle of an embodiment of the present utility model;

[0027] An embodiment of the present utility model provides an integrated column, including a column body 10, a clearance groove is provided on one side of the column body 10, and a lifting screw rod 20 is rotatably arranged in the clearance groove, one end of the lifting screw rod 20 is rotatably connected to the bottom of the column body 10, and the other end of the lifting screw rod 20 can be lifted and installed in the adjustment hole at the top of the column body 10 through a transmission mechanism. The top of the column body 10 is also provided with a driving device for driving the lifting screw rod 20 to rotate, and the driving device includes a servo motor 30 and a planetary reducer. The output end of the servo motor 30 is provided with an output shaft, and the output shaft is transmission-connected to the planetary reducer. The adjustment hole is a pear-shaped hole, and the bottom of the pear-shaped hole is also provided with a bearing rotation hole.

[0028] By adopting the servo motor 30 + planetary reducer combination, the servo motor 30 ensures speed controllability, and the planetary reducer achieves high-precision deceleration and torque increase, reducing power transmission errors; the gear meshing (driving gear 32 + driven gear 23) adopts rigid transmission, and is positioned with the circumferential mounting holes of the positioning ring to ensure a stable transmission ratio and avoid slipping or idling.

[0029] Please refer to Figure 3 as well as Figure 4 , Figure 4 This is a partial cross-sectional view of an embodiment of the present utility model. Figure 4 for Figure 3 A partial enlarged schematic diagram.

[0030] A mounting cover is installed above the adjustment hole. The servo motor 30 and planetary reducer are both mounted above the mounting cover. The bearing rotation hole includes a first bearing hole and a second bearing hole. The drive unit (servo motor 30 and planetary reducer) is mounted above the mounting cover. The transmission gear set and bearings are positioned using retaining rings and bearing holes. This eliminates the need to completely disassemble the column during assembly and disassembly, facilitating later maintenance and component replacement (such as bearings and gears).

[0031] The upper and lower rolling bearings 34 and 35 on the driving gear 32 and the tapered roller bearings 24 and deep groove ball bearings 25 on the driven gear 23 respectively bear radial loads (deep groove ball bearings 25) and axial loads (tapered roller bearings 24), reducing friction loss and vibration during transmission and ensuring gear meshing accuracy.

[0032] The bearings are installed in special bearing holes (the first and second bearing holes) with precise positioning, which further suppresses transmission eccentricity or vibration.

[0033] The bottom end of the planetary reducer is connected to a transmission column 33, which is cylindrical. A driving gear 32 is sleeved on the outside of the transmission column 33. An upper rolling bearing 34 and a lower rolling bearing 35 are provided above and below the driving gear 32, respectively. The lower rolling bearing 35 is installed in the first bearing hole. A lifting nut 22 is rotatably installed on the top of the lifting screw 20. A positioning ring is sleeved on the outside of the lifting nut 22. The positioning ring is provided with a plurality of mounting holes spaced apart along the circumferential direction. The driven gear is fixedly installed at the positioning ring through the mounting holes. 23. The outer surface of the driven gear 23 is provided with gear teeth that mesh with the gear teeth of the driving gear 32. A tapered roller bearing 24 is sleeved below the driven gear 23 of the lifting nut 22 and installed in the second bearing hole. The tapered roller bearing 24 can withstand large axial loads (to accommodate gravity or pressure during lifting), while the deep groove ball bearing 25 withstands radial loads (to balance the centrifugal force during screw rotation). Combined with the high-rigidity column body 10, it can stably support loads of varying weights (such as the wire assembly of a jigsaw machine, a worktable, etc.), and has a wide range of applications. A deep groove ball bearing 25 is sleeved above the driven gear 23 of the lifting nut 22.

[0034] The top of the lifting screw 20 is provided with a dust cover 21, which can effectively prevent dust, coolant or debris from entering the meshing area between the screw and the nut, reducing wear and extending the life of the transmission components.

[0035] A triangular convex strip is further provided on one side of the column body 10 along the length direction of the column body 10 , and both oblique side surfaces of the triangular convex strip are paved with stainless steel pads.

[0036] Working principle of this utility model:

[0037] Power input: The servo motor 30 is started, and the high-speed rotation power output is decelerated and torque-increased by the planetary reducer, and then transmitted to the transmission column 33 (cylindrical) at the bottom end of the planetary reducer, driving the transmission column 33 to rotate synchronously.

[0038] Gear Drive: The driving gear 32 on the outside of the transmission column 33 rotates with the column 33, meshing with the teeth to drive the driven gear 23 (fixed to the outside of the lifting nut 22) to rotate synchronously. The meshing relationship between the driving gear 32 and the driven gear 23 transmits power from the drive end to the lifting nut 22.

[0039] Lift conversion: lift nut 22 and lift screw 20 through the thread engagement, and the bottom of the lift screw 20 and the column body 10 bottom rotating connection. When the driven gear 23 drive lift nut 22 rotation, thread engagement produces axial force, push lift screw 20 along the column body 10 of the let out slot axial movement (up or down, direction by servo motor 30 steering control).

[0040] Auxiliary stability:

[0041] All kinds of bearings (rolling bearings, tapered roller bearings 24, deep groove ball bearings 25) to ensure the smoothness of the gear and screw rotation, reduce friction and vibration;

[0042] The above is only the preferred embodiment of the present application, and is not intended to limit the present application, any modification, equivalent replacement and improvement within the spirit and principles of the present application, should be included in the scope of protection of the present application.
