[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, a positioner for a robot welding workstation in one embodiment of the present invention includes a fixed plate 11, on which are provided a plurality of clamps 12 evenly distributed along the central axis of the fixed plate 11. The clamps 12 can move closer to and farther from each other to clamp and loosen the weldment.

[0025] The device includes a limiting plate 21 with a gap between the limiting plate 21 and the fixed plate 11. A plurality of fixing blocks 22 are fixedly connected between the limiting plate 21 and the fixed plate 11, dividing the gap into a plurality of limiting spaces by the fixing blocks 22. A plurality of height adjustment assemblies are movably connected within the plurality of limiting spaces, and a plurality of fixing assemblies are respectively disposed on the plurality of height adjustment assemblies, so that the plurality of fixing assemblies can approach the central axis of the fixed plate 11.

[0026] Specifically, the limiting plate 21 is annular and matches the fixed plate 11. The limiting plate 21 is positioned around the fixed plate 11, and the clamp 12 is located in the middle of the limiting space. The height adjustment assembly can move along the limiting space formed by the limiting plate 21 and the fixed plate 11, thereby driving the fixed assembly to move and adjust the height of the fixed assembly. Multiple fixed assemblies can approach the central axis of the fixed plate 11, thereby clamping and securing the welded parts located on the fixed plate 11.

[0027] The position where the fixing component is clamped and fixed can be located on the same vertical line as the position where the clamp 12 is clamped and fixed. The fixing component can also be moved to the position where it needs to be clamped and fixed according to actual production conditions.

[0028] The height adjustment assembly includes a sleeve 23 and a telescopic column 31. The telescopic column 31 can be telescoped in the sleeve 23. The fixing assembly is arranged at one end of the telescopic column 31 protruding from the sleeve 23 to facilitate adjustment of the height of the fixing assembly.

[0029] A plurality of first fixing holes 24 are defined within the limiting plate 21 within the limiting space, and second fixing holes 25 are defined within the sleeve 23 to match the first fixing holes 24. A first locking bolt 26 is threadedly connected between the first fixing holes 24 and the second fixing holes 25. This facilitates adjustment of the position of the sleeve 23 and facilitates its fixation. When clamping and fixing of a taller weldment is not required, the sleeve 23 can be removed without affecting the welding of normal weldments.

[0030] A plurality of fourth fixing holes 28 are provided in the sleeve 23, and a third fixing hole 27 matching the fourth fixing hole 28 is provided in the telescopic column 31. A second locking bolt 29 is threadedly connected between the third fixing hole 27 and the fourth fixing hole 28, which facilitates fixing the telescopic column 31 when the telescopic column 31 extends from the sleeve 23.

[0031] The fixing assembly includes a threaded rod 33 , a fifth fixing hole 32 matching the threaded rod 33 is defined in the telescopic column 31 , the threaded rod 33 is threadedly connected in the fifth fixing hole 32 , and a fixing piece 51 is fixedly connected to one end of the threaded rod 33 close to the central axis of the fixing plate 11 .

[0032] Rotating the threaded rod 33 drives the fixing member 51 toward the weld. As the threaded rod 33 is rotated, the fixing member 51 abuts the weld, thereby clamping and securing the weld at its middle and upper portions. A rubber pad is provided on the end of the fixing member 51 near the weld to prevent damage to the weld.

[0033] A fixing rod 52 is fixedly connected to the fixing member 51. A sixth fixing hole 35 is defined within the threaded rod 33, into which the fixing rod 52 can be threaded. To facilitate replacement of the fixing member 51, the outer end surface of the fixing member 51 is either flat or raised. A handle 34 is fixedly connected to the threaded rod 33. A receiving tray 41 is fixedly connected to the telescopic column 31. The receiving tray 41 has multiple seventh fixing holes 42 that match the fixing rods 52.

[0034] Specifically, when the clamping and fixing part of the welding part is horizontal, a fixing part 51 with a flat outer end surface can be used. When the clamping and fixing part of the welding part is concave, a fixing part 51 with a convex outer end surface can be used. The convex part can be inserted into the concave part, which can maximize the contact area between the fixing part 51 and the welding part.

[0035] The redundant fixing members 51 can be fixed to the receiving tray 41 by the fixing rods 52, so as to facilitate the quick replacement of the fixing members 51. Preferably, the receiving tray 41 can be fixed with a plurality of matching fixing members 51 according to the different shapes of the welded parts.

[0036] When using, refer to Figures 1 to 5 As shown, when the height of the weldment is high, the bottom of the weldment is fixed by the clamp 12, and the position of the sleeve 23 and the telescopic column 31 is adjusted so that the fixing part 51 and the fixing position of the weldment are on the same horizontal line. By rotating the threaded rod 33, the fixing part 51 is brought close to the weldment. Multiple fixing parts 51 can complete the clamping and fixing of the middle and upper positions of the weldment.

[0037] Compared with the prior art, the positioner for a robot welding workstation of the utility model can fix higher welded parts and ensure the stability of welding.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
