[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 8 This utility model provides a technical solution:

[0028] A three-degree-of-freedom electrically adjustable platform includes a first base 1, a second base 3, a Z-axis motor fixing side plate 8, and a Z-axis pad 14. It also includes a Z-axis fixing side plate 13, a third base 17, and a fourth base 18. The second base 3 is horizontally slidably connected to the first base 1 along the X-axis. The two Z-axis fixing side plates 13 are horizontally slidably connected to the second base 3 along the Y-axis. The Z-axis pad 14 is vertically slidably connected to the top of the Z-axis motor fixing side plate 8 along the Z-axis. The first base 1 is vertically rotatably connected above the third base 17. The third base 17 is horizontally rotatably connected to the fourth base 18.

[0029] Please see Figure 1 and Figure 5 The Z-axis pad 14 is used to connect with the fixture of the component. The second base 3 can slide along the X-axis on the first base 1 to adjust the X-axis position of the component. The Z-axis fixed side plate 13 can slide along the Y-axis on the second base 3 to adjust the Y-axis position of the component. The Z-axis pad 14 can slide along the Z-axis on the Z-axis fixed side plate 13 to adjust the Z-axis position of the component. At the same time, the vertical rotational connection between the first base 1 and the third base 17 facilitates the tilting of the component. The horizontal rotational connection between the third base 17 and the fourth base 18 facilitates the rotation of the component, thereby facilitating manual processing of the component from different directions.

[0030] It also includes an X-axis drive assembly, which includes one stepper motor 4, one lead screw nut 5 and one first lead screw 15. One stepper motor 4 is mounted on a first base 1. One first lead screw 15 is rotatably connected to the first base 1 and connected to the output end of one stepper motor 4. One lead screw nut 5 is fixedly connected to a second base 3 and threadedly connected to one first lead screw 15.

[0031] Please see Figures 1 to 4 One of the stepper motors 4 drives one of the first lead screws 15 to rotate. When the first lead screw 15 rotates, it can drive the lead screw nut 5 to translate along the axial direction, thereby realizing the horizontal movement of the X-axis of the second base 3.

[0032] It also includes a Y-axis drive assembly, which includes a second stepper motor 4, a second lead screw nut 5 and another first lead screw 15. The second stepper motor 4 is mounted on the second base 3. The other first lead screw 15 is rotatably connected to the second base 3 and connected to the output end of the second stepper motor 4. The second lead screw nut 5 is fixedly connected between the two Z-axis fixed side plates 13 and threadedly connected to the other first lead screw 15.

[0033] Please see Figures 1 to 4 The second stepper motor 4 drives another first lead screw 15 to rotate. When the first lead screw 15 rotates, it can drive the lead screw nut 5 to translate, thereby realizing the Y-axis horizontal movement of the Z-axis fixed side plate 13.

[0034] It also includes a Z-axis drive assembly, which includes a Z-axis movable top plate 12, a Z-axis fixed side plate 13, a Z-axis motor fixed plate 9, a last stepper motor 4, a second lead screw 16, and a last lead screw nut 5. The Z-axis motor fixed plate 9 is fixedly connected to the top of the two Z-axis motor fixed side plates 8. The tops of the two Z-axis fixed side plates 13 are connected to the Z-axis movable top plate 12. The Z-axis pad 14 is installed on the Z-axis movable top plate 12. The last stepper motor 4 is installed below the Z-axis motor fixed plate 9. The second lead screw 16 is vertically rotatably connected to the Z-axis motor fixed plate 9 and connected to the output end of the last stepper motor 4. The last lead screw nut 5 is fixedly connected between the two Z-axis fixed side plates 13 and threadedly connected to the second lead screw 16.

[0035] Please see Figures 1 to 4 The last stepper motor 4 drives the second lead screw 16 to rotate. When the second lead screw 16 rotates, it drives the lead screw nut 5 to translate along the axial direction, which in turn causes the lead screw nut 5 to drive the Z-axis pad 14 to move vertically through the two Z-axis fixed side plates 13, thereby realizing the Z-axis vertical movement of the Z-axis pad 14.

[0036] A coupling 6 is connected between one of the stepper motors 4 and one of the first lead screws 15, between the second stepper motor 4 and another first lead screw 15, and between the last stepper motor 4 and the second lead screw 16.

[0037] Please see Figures 1 to 4 The coupling 6 is used to realize the reliable connection and power transmission between the stepper motor 4 and the first lead screw 15 and the second lead screw 16, and also has key functions such as displacement compensation and buffering vibration reduction.

[0038] At least two first guide rails 2 are connected between the first base 1 and the second base 3, and between the second base 3 and the Z-axis motor fixing side plate 8. At least two second guide rails 10 are connected between the Z-axis motor fixing side plate 8 and the Z-axis fixing side plate 13.

[0039] Please see Figures 1 to 4 The first guide rail 2 and the second guide rail 10 are used for guiding. The model of the first guide rail 2 is MGN9C-2-R-100-Z0-HM-E10, and the model of the second guide rail 10 is MGN9C-1-R-50-Z0-HM-E5.

[0040] It should be noted that in the above structure, the stepper motors 4 are all installed through the motor mounting base 7, and the first base 1, the second base 3, the Z-axis motor fixed side plate 8, the Z-axis motor fixed top plate 9, the Z-axis movable side plate 11, the Z-axis movable top plate 12, the Z-axis fixed side plate 13 and the Z-axis pad 14 are all aluminum alloy machined parts. In addition, there is space left for the installation of the stepper motors 4, so that motors with encoders, brakes, reducers and other functions can be used to provide precise control of movement position, emergency stop and drive larger loads.

[0041] A first bracket 21 is installed at the bottom of the first base 1, and a second bracket 22 is installed on the third base 17. A rotating shaft 23 is fixedly connected to both sides of the first bracket 21, and the rotating shaft 23 is rotatably connected to the second bracket 22.

[0042] Please see Figure 5 The first base 1 can drive the rotating shaft 23 to rotate on the second support 22 through the cooperation of the first support 21 and the second support 22, so as to achieve the overall tilting of the first base 1.

[0043] It also includes a first drive assembly 19, which includes a worm gear 191, a worm 192 and a first motor 193. The worm gear 191 is coaxially fixedly connected to one of the rotating shafts 23. The worm 192 is rotatably connected to the third base 17 and cooperates with the worm gear 191. The first motor 193 is fixedly installed on the third base 17 and connected to one end of the worm 192.

[0044] Please see Figure 6 and Figure 7 The first motor 193 drives the worm 192 to rotate. When the worm 192 rotates, it can drive the worm wheel 191 to rotate, which in turn causes the worm wheel 191 to drive the rotating shaft 23 to rotate as a whole. This causes the rotating shaft 23 to drive the first base 1 to tilt as a whole through the first bracket 21. The worm wheel 191 and the worm 192 have a self-locking function.

[0045] It also includes a second drive assembly 20, which includes a second motor 201, a traction shaft 202, a gear 203 and a gear ring 204. The gear ring 204 is coaxially fixedly connected to the third base 17. The second motor 201 is mounted on the fourth base 18 through a frame and is connected to the top end of the traction shaft 202. The bottom end of the traction shaft 202 is rotatably connected to the fourth base 18. The gear 203 is coaxially fixedly connected to the traction shaft 202 and meshes with the gear ring 204.

[0046] Please see Figure 6 and Figure 8 The second motor 201 drives the traction shaft 202 to rotate, which in turn drives the gear 203 to rotate. This causes the gear 203 to drive the third base 17 to rotate as a whole on top of the fourth base 18 via the gear ring 204. Consequently, the third base 17 drives the first base 1 to rotate as a whole via the first bracket 21, the second bracket 22, and the rotating shaft 23, thereby realizing the rotation of the components.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
