[0003] At the present stage, the XXY axes of the UVW adjustment platform are arranged in the same plane, with a relatively large overall volume and a relatively small adjustment angle, which is not applicable to some special occasions where the space is narrow and the adjustment angle requirement is relatively large.
[0004] In view of this, there is an urgent need for a UVW adjustment mechanism applicable to narrow spaces. Content of the Utility Model

[0006] To achieve the above object, the utility model adopts the following technical scheme:
[0007] A UVW adjustment mechanism applicable to narrow spaces, comprising: a base, on which a horizontal movement module is arranged, the horizontal movement module includes two XY two-axis modules, the XY two-axis module includes a first sliding seat, a second sliding seat and a first driving component, the first sliding seat is slidably arranged on the base, the second sliding seat is slidably arranged on the first sliding seat, the movement direction of the first sliding seat relative to the base is perpendicular to the movement direction of the second sliding seat relative to the first sliding seat, and the first driving component is used to drive the second sliding seat to move along the X-axis direction;
[0008] A rotating table is arranged on the second sliding seat, and a carrier plate is arranged at the top of the two rotating tables, and the carrier plate is rotatably connected to both rotating tables;
[0009] The horizontal movement module further includes a second driving component for driving the carrier plate to move along the Y-axis direction.
[0010] It is further characterized in that
[0011] The movement directions of the first sliding seats of the two XY two-axis modules are perpendicular.
[0012] The first driving component includes a first motor and a first lead screw, and the first lead screw is coaxially connected to the first motor;

[0022] By upgrading the conventional XXY-axis arrangement method, one group of X-axis is designed and installed on the Y-axis, and two rotating tables are arranged on two X-axis lines.

[0026] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model and the above-mentioned accompanying drawings are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.
[0028] The following will further elaborate on this application Figure 1 - Figure 2 with reference to the accompanying drawings.
[0029] Refer to Figure 1 - Figure 2 A UVW adjustment mechanism applicable to a narrow space as shown, which includes: a base 1, a horizontal movement module is arranged on the base 1, the horizontal movement module includes two XY two-axis modules, the XY two-axis module includes a first slide 2, a second slide 3 and a first driving component, the first slide 2 is slidably arranged on the base 1, the second slide 3 is slidably arranged on the first slide 2, the movement direction of the first slide 2 relative to the base 1 is perpendicular to the movement direction of the second slide 3 relative to the first slide 2, and the first driving component is used to drive the second slide 3 to move along the X-axis; a rotating table is arranged on the second slide 3, a carrier plate 4 is arranged at the top of the two rotating tables, and the carrier plate 4 is rotatably connected to both rotating tables; the horizontal movement module further includes a second driving component for driving the carrier plate 4 to move along the Y-axis. Thus, in use, by driving the two second slides 3 to move to the same side through the two first driving components, the carrier platform moves along the X-axis. When the two first driving components drive the two second slides 3 to move in opposite directions, the carrier plate 4 rotates (when the carrier plate 4 rotates, the second slide 3 and the first slide 2 will slide relative to each other), and by driving the carrier plate 4 to move along the Y-axis through the second driving component, the position adjustment of the material on the carrier plate 4 is completed. By stacking a pair of XY axes, the problem of excessive volume caused by laying three axes flat is solved. At the same time, the number of rotating axes is reduced from the traditional 3 or 4 to two rotating tables, realizing a large-angle adjustment.
[0030] Refer to Figure 1 - Figure 2As shown, the moving directions of the first sliding seats 2 of the two XY two-axis modules are perpendicular. Thus, the moving directions of the two second sliding seats 3 are also perpendicular. That is to say, the sliding direction of the first sliding seat 2 of one XY two-axis module is the same as the sliding direction of the second sliding seat 3 of the other XY two-axis module. By doing so, the accuracy of the sliding of the first sliding seat 2 and the second sliding seat 3 during long-term operation is improved.
[0031] Reference Figure 1 - Figure 2 As shown, in order to drive the second sliding seat 3 to move in the X-axis direction to enable the carrier plate 4 to move in the X-axis direction, the first driving assembly includes a first motor 6 and a first lead screw 5. The first lead screw 5 is coaxially connected to the first motor 6. The first lead screws 5 of the two first driving assemblies are respectively threadedly connected to the first sliding seat 2 and the second sliding seat 3 of different XY two-axis modules. Thus, when the first motor 6 drives the first lead screw 5 to rotate, and the first sliding seat 2 is clamped on the base 1, and the second sliding seat 3 is clamped on the first sliding seat 2, one of the first sliding seats 2 slides relative to the base 1, and the other second sliding seat 3 slides relative to the corresponding first sliding seat 3, so as to complete the movement of the two second sliding seats 3 in the X-axis direction.
[0032] Reference Figure 1 - Figure 2 As shown, in order to drive the second sliding seat 3 to move in the Y-axis direction to enable the carrier plate 4 to move in the Y-axis direction, the second driving assembly includes a second motor 8 and a second lead screw 7. The second lead screw 7 is coaxially connected to the second motor 8 (the axis of the second lead screw 7 is perpendicular to the axis of the first lead screw 5). The second lead screw 7 is threadedly connected to the first sliding seat 2 that is not connected to the first lead screw 5. Thus, when the second motor 8 drives the second lead screw 7 to rotate, the first sliding seat 3 connected to the first lead screw 5 moves in the Y-axis direction, and further the second sliding seat 3 moves in the Y-axis direction, so as to realize the movement of the carrier plate 4 in the Y-axis direction.
[0033] Reference Figure 1 - Figure 2 As shown, the rotating table includes a rotating ring 9 and a rotating shaft 10. The rotating ring 9 is arranged on the second sliding seat 3, and the rotating shaft 10 is arranged on the carrier plate 4. The rotating ring 9 is sleeved on the rotating shaft 10. The rotating ring 9 is fixed on the second sliding seat 3 by a plurality of first bolts, and the rotating shaft 10 is fixed on the carrier plate 4 by a plurality of bolts. Thus, when the two second sliding seats 3 move in opposite directions, the two rotating shafts 10 rotate relative to the corresponding rotating rings 9, causing the carrier plate 4 to rotate. And in order to further reduce the volume of the device, two mounting holes are opened at the bottom end of the carrier plate 4, and the rotating ring 9 and the rotating shaft 10 are arranged in the corresponding mounting holes.
[0034] Further optimized, in this embodiment, the carrier plate 4 is rectangular. During actual use, the specific shape of the carrier plate 4 can be adaptively adjusted according to the use requirements.
[0035] It is further optimized that, in order to facilitate the installation of the device, a plurality of mounting holes are provided on the base 1, and the base 1 is installed by bolts through the plurality of mounting holes.
[0036] The working principle of the utility model is as follows: by upgrading the conventional XXY axis (two X-axis adjustment modules and one Y-axis adjustment module) arrangement, one set of X-axis designs is installed on the Y-axis, and the two rotating tables are arranged on the two X-axis axes. Compared with the traditional method, this layout reduces the volume, and because the two axes overlap, one set of rotating axes is reduced. For the working condition that only rotation around the axis is required, only two X-axis movements (i.e., the two first slides 2 move in opposite directions) are required to achieve it. Compared with the traditional three-point layout, the three axes need to move simultaneously to achieve it, which shortens the adjustment time. Moreover, the two-point layout is easier to achieve larger angle adjustments than the three-point layout.
[0037] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
