[0053] To more clearly demonstrate the technical solution and its effects provided by this utility model, the following detailed description of the solution provided by the embodiments of this utility model is given with reference to specific examples.
[0054] Example 1
[0055] like Figures 1 to 4 As shown, this embodiment provides a self-aligning device, comprising: a bracket 1, a base 2, a slewing bearing 3, a drive gear 4, a rotary motor 5, a first lug 6, a first universal joint shaft 7, a first cross block 8, a second lug 9, a column 10, a third lug 11, a second universal joint shaft 12, a second cross block 13, a bearing, a bearing seat 14, and a connecting shaft 15.
[0056] Define the horizontal direction of the space where the centering device is located as the x-direction, the vertical direction as the z-direction, and the direction perpendicular to the plane containing the x-direction and the z-direction as the y-direction.
[0057] The base 2 is fixed on the bracket 1; the inner ring of the slewing bearing 3 is fixed on the base 2, and its axis is along the z-direction; the outer ring gear of the slewing bearing 3 meshes with the outer tooth surface of the drive gear 4; the rotary motor 5 is fixed on the bracket 1, and its drive shaft is fixedly connected to the drive gear 4 along the axial direction.
[0058] The bottom of the first ear seat 6 is fixedly connected to the outer ring gear of the slewing bearing, and the upper part of the first ear seat 6 is hinged to the first cross block 8 along the y direction. The specific connection method is as follows: two first universal joint shafts 7 are inserted through the two ear seat holes of the first ear seat 6, and the tails of the two first universal joint shafts 7 are inserted into the cylindrical through holes of the first cross block 8 along the y direction. Bearings are set between each first universal joint shaft 7 and the cylindrical hole of the first cross block 8 to make their relative rotation smoother. The first cross block 8 also has a cylindrical through hole along the x direction, which is perpendicular to the hole in the y direction and intersects at its center point. The second ear seat 9 is set up upside down, and its bottom is fixedly connected to the column 10. The ear plate of the second ear seat 9 is hinged to the first cross block 8 along the x direction. The specific connection method is the same as the way the first ear seat 6 and the first cross block 8 are hinged along the y direction.
[0059] The bottom of the third ear seat 11 is fixedly installed on the upper part of the installed column 10. The upper part of the third ear seat 11 is hinged to the second cross block 13. The specific connection method is as follows: two second universal joint shafts 12 are inserted through the two ear seat holes of the third ear seat 11. The tails of the two second universal joint shafts 12 are inserted through the cylindrical through holes of the second cross block 13 along the y direction. Bearings are installed between each second universal joint shaft 12 and the cylindrical hole of the second cross block 13 to make their relative rotation smoother. The second cross block 13 also has a cylindrical through hole along the x direction, which is perpendicular to the hole in the y direction and intersects at its center point. The two through cylindrical holes of the second cross block 13 form a cross shape. The upper end of the connecting shaft 15 is cylindrical, and the lower end is forked. The forked lower end of the connecting shaft 15 is hinged to the second cross block 13 along the x direction. The cylindrical upper end is fitted with a bearing and is hinged to the bearing seat 14 fixed on the bracket 1.
[0060] The working principle of the self-aligning device in this embodiment is as follows:
[0061] The first ear seat 6 is fixed to the slewing bearing 3. When the slewing bearing 3 is not rotating, the first ear seat 6 is essentially fixed. The top connecting shaft 15 is hinged to the bearing housing 14 via a bearing, allowing it and the lower connected components to rotate around the z-axis. The second ear seat 9 and the third ear seat 11 are fixedly connected to the installed column 10. The first ear seat 6 is hinged to the second ear seat 9 via the first cross block 8, and the third ear seat 11 is hinged to the connecting shaft 15 via the second cross block 13. Therefore, the column 10 has unrestricted rotational freedom in the x and y directions. Thus, even if the column 10 is bent or deformed after installation, it can automatically adjust.
[0062] Among them, the base 2, slewing bearing 3, drive gear 4, and rotary motor 5 are optional accessories, which are selected when the column 10 needs to be rotated. In this case, the rotary motor 5 can be started, and the rotary motor 5 drives the drive gear 4 to rotate, thereby driving the slewing bearing 3, which meshes with it through external teeth, to rotate, and driving the column 10 and other components above it to rotate.
[0063] In summary, the self-aligning device of this embodiment, through the bearing capable of rotating in the z-direction, allows the column connected to the inner connecting shaft 15 of the bearing to have unrestricted rotational freedom in the z-direction. By setting the first and second cross-shaped blocks, the installed column can have unrestricted rotational freedom in the x and y directions, thereby automatically adjusting the rotational freedom of the long rod in the x, y, and z directions at both ends, preventing bending and stress during installation. Through the slewing bearing, in conjunction with the drive motor and drive gear, the installed column 10 can perform large-scale rotational movement in the z-direction. This self-aligning device is used when fixing the ends of a long rod, automatically adjusting the rotational freedom of the long rod in the x, y, and z directions, thereby preventing the long rod from bearing assembly stress.
