DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0026] Example

[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 . The present application provides a two-dimensional adjustment platform, in which the first base 1 is provided with a first mounting groove 18, and the first rotating member 2 can be rotatably connected to the first mounting groove 18 by a cross-roller arc guide rail, so the first rotating member 2 can slide around the direction of the Z axis (first direction), and the upper end of the first rotating member 2 is fixedly mounted with a second base 3, and the sliding of the first rotating member 2 can drive the sliding of the second base 3, and the two sides of the second base 3 are rotatably connected to the second rotating member 4 by a cross-roller arc guide rail, so the second rotating member 4 can slide around the direction of the Y axis (second direction). Specifically, the first base 1 can be installed with two bearing seats 5, and the two bearing seats 5 are respectively located on both sides of the first pusher, and a guide rod parallel to the first screw rod 7 is installed between the two bearing seats 5. The guide rod passes through the first pusher, and the first pusher can slide back and forth on the first screw rod 7 more smoothly. When the staff adjusts the angle in the Z-axis direction, the first motor 9 drives the first screw 7 to rotate (the output end of the first motor 9 is connected to the first screw 7 by a coupling). The first screw 7 is threadedly engaged with the first pusher, thereby driving the first pusher to move on the first screw 7. When the first pusher moves to the connecting member 17, the first pusher can push the connecting member 17, thereby driving the second base 3 to slide around the direction of the Z-axis. The second base 3 simultaneously drives the first rotating member 2 and the second rotating member 4 to slide around the direction of the Z-axis. When the staff adjusts the angle in the Y-axis direction, the second motor 10 drives the second screw 20 to rotate. The second screw 20 is threadedly engaged with the second pusher, thereby driving the second pusher to move on the second screw 20 (the movement range of the second pusher is within the second mounting slot 19). The second pusher has a portion extending into the elongated hole 15. During the movement process, the second pusher drives the above portion to move within the elongated hole 15. When the above portion moves to one end of the elongated hole 15, the above portion applies a thrust to the surface wall of the elongated hole 15, thereby causing the second rotating member 4 to slide in the positive direction along the Y-axis. When the above-mentioned portion moves to the other end of the elongated hole 15, it applies a thrust to the outer wall of the elongated hole 15, causing the second rotating member 4 to slide in the opposite direction along the Y-axis, thus forming a logically closed loop. In the fields of robotics, automation equipment, and precision measurement equipment, this feature allows for angle adjustment in both the Z and Y axes, eliminating the need for manual adjustment by operators. This significantly saves manpower and avoids the influence of subjective factors.

[0028] Please refer to Figure 4 In some embodiments of the present application, third mounting grooves 23 are symmetrically provided on both sides of the second base 3. First tightening assemblies are installed in the third mounting grooves 23. First limiting members 14 are installed on both sides of the second rotating member 4. The two first tightening assemblies cooperate with the two first limiting members 14 one-to-one. The first tightening assemblies can exert a reaction force on the second rotating member 4 opposite to the sliding direction. When adjusting the Y-axis angle in the positive direction, the second pusher is controlled to move forward along the extension direction of the second screw rod 20. A portion of the second pusher is located in the elongated hole 15. When the portion moves to one end of the elongated hole 15, the portion applies a thrust to the surface wall of the elongated hole 15. The second rotating member 4 slides forward along the Y-axis, simultaneously driving the first limiting member 14 to slide forward along the Y-axis. During the movement, the first limiting member 14 presses against the first tightening assembly. The first tightening assembly deforms under the pressure. After the deformation, the first tightening assembly exerts a reaction force on the first limiting member 14. The direction of the reaction force is opposite to the sliding direction of the first limiting member 14. When adjusting the Y-axis angle in the reverse direction, the second pusher is controlled to move in the reverse direction along the extension direction of the second screw rod 20. When the portion moves to the other end of the elongated hole 15, it applies a thrust to the surface wall of the elongated hole 15, causing the second rotating member 4 to slide in the reverse direction along the Y-axis. It should be noted that without the first tightening assembly, when the second rotating member 4 switches from forward sliding to reverse sliding, the portion of the second pusher must move from one end of the elongated hole 15 to the other end of the elongated hole 15 in order to push the second rotating member 4 to slide in the reverse direction along the Y-axis. This not only results in a large motion gap, but also reduces the accuracy of angle adjustment. In the present application, when the second rotating member 4 switches from forward sliding to reverse sliding, the portion of the second pusher leaves the surface wall of one end of the elongated hole 15 and no longer limits the second rotating member 4. At this time, the first tightening assembly applies a reaction force to the first stopper 14, which can push the second rotating member 4 to slide in the reverse direction along the Y-axis, thereby promptly responding to the angle adjustment command, reducing the motion gap, and improving the accuracy of angle adjustment.

[0029] Please refer to Figure 4 and Figure 5In some embodiments of the present application, the first tightening assembly is composed of a first tightening member 25 and a first return spring 24. The first tightening member 25 can tighten the first limiting member 14 under the action of the first return spring 24. One end of the first return spring 24 is connected to the surface wall of the third mounting groove 23, and the other end of the first return spring 24 is connected to the first tightening member 25. When the Y-axis angle is adjusted in the positive direction, the second rotating member 4 slides along the positive direction of the Y-axis, thereby driving the first limiting member 14 to slide along the positive direction of the Y-axis. During the sliding process, the first limiting member 14 presses against the first tightening member 25, thereby compressing the first return spring 24. At this time, the first tightening member 25 applies a force in the opposite direction of the Y-axis to the first limiting member 14. When the Y-axis angle is adjusted in the opposite direction, the above-mentioned force can cause the second rotating member 4 to slide in the opposite direction of the Y-axis for the first time, greatly improving the response rate.

[0030] Please refer to Figure 3 . In some embodiments of the present application, when adjusting the Z-axis angle in the positive direction, the first pusher is controlled to move in the positive direction along the extension direction of the first screw rod 7, and the first pusher can push the connecting member 17, so that the second base 3 rotates in the positive direction along the Z-axis. During the positive rotation of the second base 3, the second tightening assembly is driven to rotate, and the second tightening assembly is pressed against the second limiting member 11. The second tightening assembly is deformed after being subjected to pressure, and the second limiting member 11 applies a reaction force to the deformed second tightening assembly, and the direction of the reaction force is opposite to the sliding direction of the second limiting member 11. When adjusting the Z-axis angle in the reverse direction, the first pusher is controlled to move in the reverse direction along the extension direction of the first screw rod 7. When the first pusher just leaves the connecting member 17, the reaction force can immediately push the second base 3 to rotate in the reverse direction along the Z-axis. In this way, the angle adjustment command can be responded to in a timely manner, the movement gap can be reduced, and the accuracy of the angle adjustment can be improved.

[0031] In some embodiments of the present application, when adjusting the Z-axis angle in the positive direction, the second base 3 rotates in the positive direction, the second pressing member 13 presses against the second limit member 11, and the second return spring 12 is compressed. When adjusting the Z-axis angle in the negative direction, the first pusher is controlled to move in the opposite direction along the extension direction of the first screw rod 7. When the first pusher just leaves the connecting member 17, the second return spring 12 recovers its deformation, thereby driving the second base 3 to rotate in the opposite direction.

[0032] Please refer to Figure 2. In some embodiments of the present application, one end of the first screw rod 7 is connected to the first motor 9 through a coupling, and the other end of the first screw rod 7 is rotatably connected through the bearing seat 5, which improves the overall strength and rigidity of the first screw rod 7, thereby improving the overall stability. The first sliding portion 6 is provided with a first threaded opening and a guide opening that are threadedly matched with the first screw rod 7. The first screw rod 7 passes through the first threaded opening, and the guide rod passes through the guide opening. The threaded matching of the first screw rod 7 and the first sliding portion 6 can make the first sliding portion 6 move along the extension direction of the first screw rod 7, so that the first pushing portion 16 can push the connecting member 17, driving the second base 3 to slide along the positive direction of the Z axis.

[0033] Please refer to Figure 4 and Figure 5 In some embodiments of the present application, the second sliding portion 21 is provided with a second threaded opening that is threadedly engaged with the second screw rod 20, and the second pushing portion 22 is located in the elongated hole 15. The second sliding portion 21 moves along the extension direction of the second screw rod 20 to drive the second pushing portion 22 to move in the elongated hole 15. On the one hand, the second pushing portion 22 can act on the surface wall of the elongated hole 15, thereby driving the second rotating member 4 to move along the Y-axis direction. On the other hand, the hole width of the elongated hole 15 is adapted to the outer diameter of the second pushing portion 22, and the second pushing portion 22 can also guide the second sliding portion 21.

[0034] In summary, the embodiments of the present invention provide a two-dimensional adjustment platform. When a worker adjusts the angle in the Z-axis direction, the first motor 9 rotates the first screw 7, which engages with the first pusher in a threaded engagement with the first pusher, thereby driving the first pusher to move on the first screw 7. When the first pusher moves to the connecting member 17, the first pusher can push the connecting member 17, thereby driving the second base 3 to slide about the Z-axis. The second base 3 simultaneously drives the first rotating member 2 and the second rotating member 4 to slide about the Z-axis. When a worker adjusts the angle in the Y-axis direction, the second motor 10 rotates the second screw 20, which engages with the second pusher in a threaded engagement with the second pusher, thereby driving the second pusher to move on the second screw 20. The second pusher has a portion extending into the elongated hole 15. During movement, the second pusher drives this portion to move within the elongated hole 15. When this portion moves to one end of the elongated hole 15, it applies a thrust to the outer wall of the elongated hole 15, causing the second rotating member 4 to slide in the positive direction along the Y-axis, forming a logical closed loop. In the fields of robots, automation equipment, and precision measuring equipment, the angle can be adjusted in the Z-axis and Y-axis directions, eliminating the need for workers to manually adjust the angle, greatly saving manpower and avoiding the influence of human subjective factors.

It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
