[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0040] See Figures 1 to 14 The intermediate leg welding fixture shown includes a worktable 1, a first positioning device 10, a second positioning device 20, a third positioning device 30, a clamping device 40, a crossbeam positioning device 50, and a control switch for controlling the operation of the clamping device 40. In this embodiment, the control switch is preferably a pneumatic switch.

[0041] The workbench 1 comprises two horizontal plates and two vertical plates. The two horizontal plates include an upper horizontal plate 1a and a lower horizontal plate 1b, and the two vertical plates include a left vertical plate 1c and a right vertical plate 1d. In this embodiment, the middle leg 2 consists of a middle leg upper horizontal beam 2a, two middle leg horizontal beam connectors 2b arranged on both sides of the middle leg upper horizontal beam 2a and connected to the middle leg upper horizontal beam 2a, and two middle leg posts 2c arranged on both sides of the middle leg upper horizontal beam 2a and connected to the middle leg upper horizontal beam 2a.

[0042] The first positioning device 10 is disposed on the workbench 1 and is used to limit the movement of the intermediate leg 2. In this embodiment, the first positioning device 10 includes two first positioning blocks 11 and two first positioning plates 12 disposed on the two vertical plates. The two first positioning blocks 11 are respectively provided with first circular holes 11a for inserting the two intermediate leg crossbeam connectors 2b. The two first positioning plates 12 are provided with first U-shaped grooves 12 for clamping the crossbeam 2a of one intermediate leg. Specifically, the left vertical plate 1c and the right vertical plate 1d are each provided with one first positioning block 11 and one first positioning plate 12 and are arranged symmetrically.

[0043] The second positioning device 20 is disposed on the workbench 1 and is used to limit the position of the intermediate foot 2. In this embodiment, the second positioning device 20 includes two second positioning blocks 21 disposed on the left vertical plate 1c. The two second positioning blocks 21 are provided with second L-shaped grooves 21a for limiting the position of the intermediate foot post 2c. Specifically, the two second positioning blocks 21 are respectively arranged at the top and bottom of the left vertical plate 1c.

[0044] The third positioning device 30 is disposed on the workbench 1 and is used to limit the position of the intermediate foot 2. In this embodiment, the third positioning device 30 includes two third positioning blocks 31 disposed on the right vertical plate 1d. The two third positioning blocks 31 are provided with third L-shaped grooves 31a for limiting the position of the two intermediate foot posts 2c. Specifically, the two third positioning blocks 31 are respectively arranged at the top and bottom of the right vertical plate 1d.

[0045] A clamping device 40 is mounted on the workbench 1 and is used to clamp the intermediate foot 2. In this embodiment, the clamping device 40 includes several clamping cylinders mounted on the workbench 1 and used to clamp the intermediate foot 2. Each clamping cylinder 40 is equipped with a robotic arm 41 for clamping the intermediate foot 2. Specifically, there are five clamping cylinders 40: three clamping cylinders 40 are mounted on the upper horizontal plate 1a, one clamping cylinder 40 is mounted on the left vertical plate 1c, and the other clamping cylinder 40 is mounted on the right vertical plate 1d.

[0046] The beam positioning device 50 is set on the workbench 1 and is used to position the intermediate foot 2. In this embodiment, the beam positioning device 50 includes a beam positioning platform 51 set on the workbench 1 and a beam positioning component 52 set on the beam positioning platform 51. The beam positioning platform 51 is provided with holes 51a for screws to pass through and can be adjusted according to the intermediate foot 2 of different lengths.

[0047] It also includes a fourth positioning device 60 set on the workbench 1 for positioning intermediate feet 2 of different sizes. In this embodiment, the fourth positioning device 60 includes a fourth positioning block 61 set on the upper horizontal plate 1a, and the fourth positioning block 61 is provided with a fourth circular hole 61a for the intermediate feet 2 to be inserted. In use, the following steps are taken: First, clean the surfaces of the devices, workbench 1, and workpiece to remove iron filings, dirt, dust, etc., ensuring that there are no foreign objects between the workbench 1 and the workpiece. Adjust the workbench 1 to the depressurization state using a pneumatic switch. The mechanical arms 41 with several clamping cylinders 40 rise and rotate outwards. Fix the crossbeam positioning component 52 to the corresponding hole 51a on the crossbeam positioning platform 51 using screws (different lengths of intermediate legs correspond to different holes 51a on the crossbeam positioning platform 51). Align the intermediate leg posts 2c and the intermediate leg crossbeam connectors 2b sequentially with their oblong holes and place them onto the upper crossbeam 2a of the intermediate leg. The two intermediate leg crossbeam connectors 2b are respectively attached to the two first positioning blocks 11, which limit the bottom and sides of the intermediate leg crossbeam connectors 2b. The two first positioning plates 12 clamp the upper crossbeam 2a of the intermediate leg. Then, move the two intermediate leg posts 2c to... The sides and bottom of 2c are respectively attached to the two second positioning blocks 21 and the third positioning block 31 at the bottom of the workbench 1. Finally, the middle foot upper crossbeam 2a is moved left and right so that the right side of the middle foot upper crossbeam 2a is aligned with the crossbeam positioning part 52. At this time, the middle foot upper crossbeam 2a, the middle foot column 2c, and the middle foot crossbeam connector 2b have all been limited except for the upper surface. The air pressure switch is turned on, and several clamping cylinders 40 are adjusted to the air intake and pressurization state. The mechanical arm 41 of the clamping cylinder 40 rotates 90 degrees to the top of the middle foot 2, and at the same time retracts downward to press down the upper surface of the middle foot upper crossbeam 2a and the two middle foot columns 2c. After all the parts are clamped, the splicing parts of the middle foot upper crossbeam 2a, the middle foot column 2c, and the middle foot crossbeam connector 2b are welded to form a whole. Since the welded parts are clamped and fixed, they will not deform or misalign due to welding heat or other factors during the welding process, thus ensuring the verticality of the product after welding and cooling. After welding and fixing, the workbench 1 is adjusted to the depressurization state by the air pressure switch. The mechanical arm 41 with several clamping cylinders 40 rises and rotates outward. The bottom of the mechanical arm 41 separates from the upper surface of the middle foot upper crossbeam 2a and the middle foot column 2c, and the welded workpiece is taken out vertically upward.

[0048] When welding intermediate legs 2 of different lengths, the steps are the same as above. For different lengths, it is only necessary to adjust the crossbeam positioning piece 52 to the different holes 51a on the crossbeam positioning platform 51. When welding a single-sided intermediate leg with a length of 560cm, since there is only one intermediate leg crossbeam connector, this intermediate leg crossbeam connector needs to be aligned with the fourth circular hole 61a on the fourth positioning block 61. Other steps remain unchanged.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
