[0039] The first positioning device 10 is set on the workbench 1 and is used to limit the double-sided slanted V-shaped feet 100. In this embodiment, the first positioning device 10 includes two first positioning blocks spaced apart on the upper horizontal plate 2a. Each first positioning block is provided with a circular groove 10a for the side foot beam connector 120 to be inserted.

In this embodiment, the second positioning device 20 includes two second positioning blocks mounted on the two inclined plates 3. Each second positioning block is provided with a U-shaped groove 20a for the insertion of the crossbeam 110 on the side foot. Specifically, a second positioning block is provided on each of the left inclined plate 3a and the right inclined plate 3b.

[0041] The third positioning device 30 is disposed on the workbench 1 and is used to position the double-sided slanted feet 100. In this embodiment, the third positioning device 30 includes two third positioning blocks disposed on the two inclined plates 3, and each third positioning block is provided with a groove 30a for the inclined foot post 130 to be inserted. Specifically, two third positioning blocks are disposed on the left inclined plate 3a and the right inclined plate 3b respectively.

[0042] The beam positioning device 40 is set on the workbench 1 and is used to position the double-sided slanted V-shaped feet 100. In this embodiment, the beam positioning device 40 includes a beam positioning platform 41 set on the upper horizontal plate 2a and a beam positioning component 42 detachably connected to the beam positioning platform 41 by screws. The beam positioning platform 41 is provided with holes 41a for screws to pass through and can be adjusted according to different lengths of the double-sided slanted V-shaped feet 100.

[0043] The clamping device 50 is mounted on the workbench 10 and is used to press the double-sided slanted feet 100 into the glue container. In this embodiment, the clamping device 50 includes several clamping cylinders 51 mounted on the upper horizontal plate 2a, the left slanted plate 3a, and the right slanted plate 3b. Each clamping cylinder 51 is fixed to the upper horizontal plate 2a, the left slanted plate 3a, and the right slanted plate 3b by a clamping base 52. Specifically, there are four clamping cylinders 51, with two clamping cylinders 51 fixed on the upper horizontal plate 2a and the other two clamping cylinders 51 respectively mounted on the left slanted plate 3a and the right slanted plate 3b.

[0044] When using this invention, firstly, the surfaces of each device platform and workpiece are cleaned to remove iron filings, dirt, dust, etc., ensuring that there are no foreign objects between the platform and the workpiece. Then, the worktable 1 is adjusted to the exhaust and depressurization state using a pneumatic switch, and each clamping cylinder 51 is in the state of the arm rising and rotating outward. The crossbeam positioning component 42 is fixed to the corresponding hole 41a on the crossbeam positioning platform 41 using screws (different lengths of crossbeams correspond to different positioning holes on the crossbeam positioning platform). The inclined side foot column 130 and the side foot crossbeam connector 120 are used to... The waist-shaped holes are used to align the two parts sequentially onto the side crossbeam 110. The two side crossbeam connectors 120 are respectively attached to the circular grooves 10a of the two first positioning blocks 10. The two first positioning blocks 10 limit the bottom and sides of the side crossbeam connectors 120. The side crossbeam 110 is attached to the U-shaped grooves 20a of the two second positioning blocks. Then, the two inclined side legs 130 are moved so that the sides and bottoms of the inclined side legs 130 are respectively attached to the grooves 30a of the two third positioning blocks at the bottom of the worktable 1. Finally, the side crossbeam 110 is moved left and right. 0. Align the right side of the upper crossbeam 110 with the crossbeam positioning component 42. At this point, the upper crossbeam 110, the inclined side foot post 130, and the side crossbeam connector 120 are all in position except for their upper surfaces. Turn on the air pressure switch, and all four clamping cylinders 51 are simultaneously adjusted to the air intake and pressurization state. The arms of the clamping cylinders 51 rotate 90 degrees to above the upper crossbeam 110 and retract downwards to press down on the upper crossbeam 110 and the upper surfaces of the two inclined side foot posts 130. After all components are clamped, the upper crossbeam 110, the inclined side foot post 130, and the side crossbeam connector 120 are aligned. Welding is performed at the joints of the foot beam connector 120 to form a whole. Since the welded parts are clamped and fixed, they will not deform or misalign due to factors such as welding heat during the welding process, thus ensuring the verticality of the product after welding and cooling. After welding and fixing, the worktable 1 is adjusted to the depressurization state by the air pressure switch, the arm of the clamping cylinder 51 rises and rotates outward, and the arm of the clamping cylinder 51 separates from the upper surface of the side foot beam 110 and the inclined side foot column 130. Finally, the welded workpiece is taken out vertically upward.
