[0043] 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.

[0044] See Figures 1 to 17 The illustrated welding fixture for crossbeams includes a worktable 10, several positioning blocks 20, a first positioning device 30, a second positioning device 40, a third positioning device 50, a fourth positioning device 60, and a control switch for controlling the operation of the first positioning device 30, the second positioning device 40, the third positioning device 50, and the fourth positioning device 60. In this embodiment, the control switch is preferably a pneumatic switch for operating the first positioning device 30, the second positioning device 40, the third positioning device 50, and the fourth positioning device 60.

[0045] A plurality of positioning blocks 20 are disposed on the workbench 10 and are used for placing the crossbeam tube 1 and limiting the crossbeam tube 1. In this embodiment, the plurality of positioning blocks 20 include a first positioning block 21 and a second positioning block 22. The first positioning block 21 and the second positioning block 22 are respectively provided with a first placement groove 21a and a second placement groove 22a for placing the crossbeam tube 1.

[0046] The first positioning device 30 is mounted on the workbench 10 and is used to position the crossbeam tube 1. In this embodiment, the first positioning device 30 includes a first cylinder 31 mounted on the workbench 10 and connected to a control switch. The positioning circular portion 31a of the first cylinder 31 engages with the side of the crossbeam tube 1. To fix the first cylinder, the first cylinder 31 is fixed to the workbench 10 by a first connecting plate 32.

[0047] The second positioning device 40 is disposed on the workbench 10 and is used to position the crossbeam tube 1. In this embodiment, the second positioning device 40 includes a second cylinder 41 disposed on the workbench 10 and connected to a control switch. The positioning boss surface 41a of the second cylinder 41 mates with the side opening 1a of the crossbeam tube 1. To fix the second cylinder, the second cylinder 41 is fixed to the workbench 10 by a second connecting plate 42.

[0048] The third positioning device 50 is slidably disposed on the worktable 10 and is used to place the crossbeam welding piece 2 and push the crossbeam welding piece 2 into the crossbeam tube 1. In this embodiment, the third positioning device 50 includes a third cylinder 51 slidably disposed on the worktable 10 and connected to the control switch. The third cylinder 51 is provided with a positioning pin 52 for placing the crossbeam welding piece 2.

[0049] A fourth positioning device 60 is mounted on the worktable 10 and is used to drive the third positioning device 50 to extend and retract. In this embodiment, the fourth positioning device 60 includes a fourth cylinder 61 mounted on the worktable 10 and connected to a control switch. The fourth cylinder 61 is provided with a sliding plate 61a connected to the third cylinder 51 and for the positioning pin 52 to pass through. To allow the sliding plate 61a to move left and right, the fourth cylinder 61 is fixed to the worktable 10 by a third connecting plate 62. A guide rod 63 is provided between the third connecting plate 62 and the second connecting plate 42 to allow the sliding plate 61a to move left and right. Specifically, the middle part of the sliding plate 61a is provided with an oblong hole that mates with the positioning pin 52.

[0050] In use, the following steps are taken: First, clean the surfaces of all devices, the workbench, and the workpiece to remove iron filings, dirt, dust, etc., from the workbench surface, ensuring there are no foreign objects between the workbench and the workpiece. Then, adjust the workbench 10 to the exhaust and depressurization state using a pneumatic switch, causing the first cylinder 31, second cylinder 41, third cylinder 51, and fourth cylinder 61 to be in a retracted state. Place the crossbeam tube 1 vertically downwards onto the first positioning block 21 and the second positioning block 22 of the workbench 10. The first and second positioning blocks 21 and 22 limit the bottom and side surfaces of the crossbeam tube 1. The crossbeam tube 1 is then positioned on the first and second positioning blocks 21 and 22 of the workbench 10. Afterwards, the crossbeam tube 1 moves towards the first cylinder 31 until the opening 1a on the side of the crossbeam tube 1 is flush with the positioning boss surface 41a of the second cylinder 41. The pneumatic switches of the first cylinder 31 and the second cylinder 41 are turned on, and the first cylinder 31 and the second cylinder 41 are adjusted to the air intake and pressurization state. The first cylinder 31 and the second cylinder 41 extend outwards simultaneously, causing the positioning boss surface 41a on the first cylinder 31 and the second cylinder 41 to move outwards, thus squeezing and fixing the crossbeam tube 1. The positioning pin 52 on the third cylinder 51 is used to fix the crossbeam welding piece 2 to the outer surface of the third cylinder 51. The pneumatic switch of the fourth cylinder 61 is turned on, and the fourth cylinder 61 is adjusted... In the intake pressurization state, the fourth cylinder 61 extends and retracts, causing the third cylinder 51 to move towards the second cylinder 41 until it is flush with the second connecting plate 42 at the second cylinder 41. The air pressure switch of the third cylinder 51 is turned on to adjust to the intake pressurization state. The extension and retraction of the third cylinder 51 causes the crossbeam welding piece 2 to move outward, pushing the crossbeam welding piece 2 into the interior of the crossbeam tube 1. The air pressure switch is then used to adjust the third cylinder 51 and the fourth cylinder 61 to the depressurization state, and the third cylinder 51 and the fourth cylinder 61 are reset (due to the friction between the crossbeam welding piece 2 and the inner surface of the crossbeam tube 1, the crossbeam welding piece 2 will not loosen or fall off during the reset process of the third cylinder 51). The crossbeam is then faced from the outside. Welding is performed at the connection between welding piece 2 and crossbeam tube 1 to form a whole. Because it is clamped and fixed, it will not deform or misalign due to factors such as welding heat during the welding process, thus ensuring the verticality and accuracy of the product after welding and cooling, and avoiding height differences when assembling crossbeam tube 1 and edge feet. After the crossbeam welding piece 2 is welded and fixed, the first cylinder 31 and the second cylinder 41 are adjusted to the depressurization state through the air pressure switch. The first cylinder 31 and the second cylinder 41 retract inward, and the positioning circular part 31a and the positioning boss surface 41a on the first cylinder 31 and the second cylinder 41 are released from the crossbeam tube 1. The welded workpiece is then taken out vertically upward.

[0051] 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.
