Description

Technical Field

[0001] This utility model relates to the technical field of two-axis adjustable bases, specifically to a slider docking type two-axis platform. Background Technology

[0002] Refer to the accompanying drawings in the instruction manual. Figure 1-2 In existing two-axis adjustable platforms, two parallel X-axis guide rails 12 are typically laid on a base 11, with an X-axis ball screw 13 laid parallel between the two X-axis guide rails 12. An adjustable X-axis base plate 14 is then mounted on the sliders of the two X-axis guide rails, and the adjustable X-axis base plate 14 is fixed to the nut of the X-axis ball screw 13, thus forming one axis (X-axis) of the two-axis platform. Then, two parallel Y-axis guide rails 15 are laid on the adjustable X-axis base plate 14, with the Y-axis guide rails 15 perpendicular to the X-axis guide rails 12. A Y-axis ball screw 16 is laid between the two Y-axis guide rails 15, and a device mounting base plate 17 is mounted on the sliders of the two Y-axis guide rails 15, and the device mounting base plate 17 is fixed to the nut of the Y-axis ball screw 16, thus forming the other axis (Y-axis) of the two-axis platform. The position of the device mounted on the mounting base plate 17 in the X and Y directions can be adjusted by moving the ball screws (13, 16) on two axes driven by a motor. This arrangement requires an adjustable base plate 14 on the nut of the X-axis ball screw 13 to mount the Y-axis guide rail 15 and the Y-axis ball screw 16. When the device size is large, the distance between the two guide rails on the X and Y axes is large, and the size of the adjustable base plate 14 will also be very large, which not only increases the structural weight and cost, but also reduces the system response speed and sensitivity of the motion system, and increases the electrode load due to the excessive weight of the moving parts.

The Y-axis slider on the Y-axis guide rail is fixedly connected to the X-axis slider on the X-axis guide rail, and the Y-axis nut on the Y-axis ball screw is fixedly connected to the X-axis nut on the X-axis ball screw.

[0007] Preferably, it also includes an X-axis motor connected to the X-axis ball screw and a Y-axis motor connected to the Y-axis ball screw. The X-axis motor is fixedly mounted on the base, and the Y-axis motor is fixedly mounted on the equipment mounting base plate.

[0009] Preferably, the Y-axis slider on the Y-axis guide rail and the X-axis slider on the X-axis guide rail are fixedly connected by threaded fasteners or snap-fit.

[0010] Preferably, both the X-axis guide rail and the X-axis ball screw are mounted on the upper surface of the base.

[0020] X-axis guide rail 2 and Y-axis guide rail 5 are respectively equipped with X-axis slider 21 and Y-axis slider 51 that are slidably mounted thereon; X-axis guide rail 2 and X-axis ball screw 3 are both mounted on base 1. Equipment mounting base plate 4 is located above base 1, and Y-axis guide rail 5 and Y-axis ball screw 6 are both mounted on the lower plate surface of equipment mounting base 1. Y-axis slider 51 on Y-axis guide rail 5 is fixedly connected to X-axis slider 21 on X-axis guide rail 2, and Y-axis nut 61 on Y-axis ball screw 6 is fixedly connected to X-axis nut 31 on X-axis ball screw 3, thus eliminating the need for a middle mounting plate structure. This design simplifies the structure and contributes to the lightweight and miniaturization of the two-axis platform. On the other hand, the lightweight and miniaturized structure can improve the system response speed, making the movement of each axis more sensitive, while reducing the load on the motor during acceleration and deceleration, allowing the motion system to meet the requirements with a lower specification motor and reducing costs.

[0021] Specifically, it also includes an X-axis motor connected to the X-axis ball screw 3 and a Y-axis motor connected to the Y-axis ball screw 6. The X-axis motor is fixedly mounted on the base 1, and the Y-axis motor is fixedly mounted on the equipment mounting base plate 4.

[0022] In a further embodiment, the Y-axis nut 61 on the Y-axis ball screw 6 and the X-axis nut 31 on the X-axis ball screw 3 are fixedly connected by threaded fasteners. The Y-axis slider 51 on the Y-axis guide rail 5 and the X-axis slider 21 on the X-axis guide rail 2 are fixedly connected by threaded fasteners to facilitate quick assembly and disassembly. Alternatively, the Y-axis nut 61 on the Y-axis ball screw 6 and the X-axis nut 31 on the X-axis ball screw 3 can also be fixedly connected by a snap-fit ​​mechanism. The Y-axis slider 51 on the Y-axis guide rail 5 and the X-axis slider 21 on the X-axis guide rail 2 can also be fixedly connected by a snap-fit ​​mechanism.

[0023] In a further embodiment, both the X-axis guide rail 2 and the X-axis ball screw 3 are mounted on the upper surface of the base 1. There are two X-axis guide rails 2, which are parallel to each other; the X-axis ball screw 3 is positioned between the two X-axis guide rails 2. There are two Y-axis guide rails 5, which are parallel to each other; the Y-axis ball screw 6 is positioned between the two Y-axis guide rails 5.

[0024] As can be seen from the above, this utility model directly mounts the Y-axis guide rail 5 and the Y-axis ball screw 6 onto the equipment mounting base plate 4, and fixes the slider of the Y-axis guide rail 5 and the slider of the X-axis guide rail 2 together, and fixes the nut of the Y-axis ball screw together with the nut of the X-axis ball screw together. This eliminates the need for an intermediate mounting plate, simplifies the structure, and helps to make the two-axis platform lighter and smaller, making the movement of each axis more sensitive and reducing the load on the motor during acceleration and deceleration.
