[0027] By pulling the clamping rod 13, the limit of the clamping rod 13 on the clamping slot 12 can be released, and then the adjusting rod 10 is rotated to adjust the rotation angle of the first rotating plate 11 and the second rotating plate 18, thereby providing convenience for placing the parts to be welded on the base 1, and effectively reducing the probability of collision between the parts to be welded and the positioning seat and the clamping device during the placement process.

[0028] A first fastener is provided between the first positioning seat 3 and the first rotating plate 11 and between the second positioning seat 17 and the second rotating plate 18 . The first fastener is used to fasten the lifter side plate and the lifter pull rod connecting plate.

[0029] The second fastener is arranged between the two sleeves 7 and is used for fastening the lifting shaft connecting sleeve for facilitating welding. The third fastener is arranged on the positioning plate 8 and is used for fastening the lifting device supporting cushion block.

[0030] The first fastener includes the limiting hole 4, and a plurality of limiting holes 4 are arranged on the first positioning seat 3, the first rotating plate 11, the second positioning seat 17 and the second rotating plate 18 in the horizontal direction. The limiting holes 4 on the first positioning seat 3 and the first rotating plate 11 are arranged opposite to each other, the cylinder 2 is fixedly installed on the first positioning seat 3, and the telescopic shaft of the cylinder 2 slidably penetrates through the first positioning seat 3 and extends between the first positioning seat 3 and the first rotating plate 11.

[0031] In use, long shafts are respectively inserted into the limiting holes 4 arranged opposite to each other on the first positioning seat 3 and the first rotating plate 11, the long shafts are used for limiting the top of the lifting device side plate, then the telescopic shaft of the cylinder 2 is controlled to be elongated to cooperate with the first positioning seat 3, so that the lifting device side plate is clamped and fixed.

[0032] The limiting holes 4 on the second positioning seat 17 and the second rotating plate 18 are arranged opposite to each other, the cylinder 2 is fixedly installed on the second positioning seat 17, and the telescopic shaft of the cylinder 2 slidably penetrates through the second positioning seat 17 and extends between the second positioning seat 17 and the second rotating plate 18.

[0033] In use, long shafts are respectively inserted into the limiting holes 4 arranged opposite to each other on the second positioning seat 17 and the second rotating plate 18, the long shafts are used for limiting the top of the lifting device pull rod connecting plate, then the telescopic shaft of the cylinder 2 is controlled to be elongated to cooperate with the second positioning seat 17, so that the lifting device pull rod connecting plate is clamped and fixed.

[0034] The second fastener is specifically a shaft top tightening threaded hole (not shown in the figure), and one shaft top tightening threaded hole is arranged on the top of each of the two sleeves 7. The lifting shaft connecting sleeve is arranged between the two sleeves 7, the long shaft is connected by penetrating through the sleeve 7 and the lifting shaft connecting sleeve, and the long shaft is tightly fixed by the cooperation of the external locking bolt (not shown in the figure) and the shaft top tightening threaded hole, so as to facilitate the smooth welding of the lifting shaft connecting sleeve.

[0035] The third fastener is specifically a top tightening hole 9, the lifting device supporting cushion block is arranged between the positioning plate 8 and the two sleeves 7, and the screw (not shown in the figure) is used for cooperating with the top tightening hole 9 to realize the clamping and fixing of the lifting device supporting cushion block.

[0036] The second fastener and the third fastener in the scheme correspond to the shaft sleeve fixing seat and the supporting cushion block positioning seat mentioned in the patent with the publication number CN217942337U, and therefore the second fastener and the third fastener are not described in detail.

[0037] Working Principle: Initially, both the first and second positioning seats 3 and 17 are perpendicular to the base 1. During operation, the lever 13 is pulled to disengage from the slot 12, releasing the restraint on the adjustment rod 10. During this process, the limiting plate 14 slides within the limiting slot 15 toward the tension spring 16, gradually increasing the tension deformation of the spring 16.

[0038] Then, the adjusting rod 10 is rotated, which drives the first rotating plate 11 and the second rotating plate 18 to rotate. The first rotating plate 11 and the second rotating plate 18 stop when they rotate to be level with the base 1. The locking rod 13 is released, and the locking rod 13 is engaged in the locking groove 12 of the adjusting rod 10 under the elastic action of the spring 16, thereby re-fixing the first rotating plate 11 and the second rotating plate 18.

[0039] Next, place the rear plate of the lifter on the support block 6 so that it is in a suitable position to ensure that the first rotating plate 11 and the second rotating plate 18 do not collide with the base 1 when they are perpendicular to the base 1. Then, pull the clamping rod 13 again according to the above operation to control the first rotating plate 11 and the second rotating plate 18 to be perpendicular to the base 1.

[0040] After adjusting the first rotating plate 11 and the second rotating plate 18, place the two lifter side plates corresponding to the sides of the first positioning seat 3 and the first rotating plate 11, and insert the long axis into the limiting holes 4 facing the first positioning seat 3 and the first rotating plate 11 to ensure the parallelism of the two side plates and their perpendicularity to the rear plate.

[0041] At the same time, the upper pull rod connecting plate of the lifter is placed between the second positioning seat 17 and the second rotating plate 18 on the rear plate of the lifter, and the long axis is inserted into the corresponding limiting holes 4 of the second positioning seat 17 and the second rotating plate 18 for positioning and holding.

[0042] Then, use the long shaft to install the lifter connecting sleeve, insert it into the sleeve 7 for positioning, push the lifter rear plate to make it rest on the two sleeves 7, and fix the lifter support pad on the positioning plate 8 with screws.

[0043] Finally, place the reinforcement ribs of the lifter in the appropriate positions according to the drawings and clamp the parts with the corresponding fixing clips, then start welding.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
