However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figure 1 and Figure 2 As shown, a welding tool involved in this embodiment includes a welding base plate 1, on which are provided two rectangular tube welding stations 2 that are symmetrically arranged and extend forward and backward. The welding base plate 1 is also provided with a plurality of short square tube welding stations 3 that are equidistantly arranged and extend forward and backward. The short square tube welding station 3 is located between the two rectangular tube welding stations 2.

[0018] A first positioning block 4 is provided at one end of the rectangular tube welding station 2, and a second positioning block 5 is provided at one side of the rectangular tube welding station 2. The second positioning block 5 and the first positioning block 4 are both fixedly connected to the welding base plate 1;

[0019] One side of the short square tube welding station 3 is provided with a third positioning block 6 fixedly connected to the welding base plate 1, and the other side is provided with a cam shaft 7 rotatably connected to the welding base plate 1. One end of the cam shaft 7 is provided with a clamping cam 8 for follow-up, and the other end is transmission-connected to a driving mechanism for controlling the rotation.

[0020] Furthermore, the driving mechanism includes a gear 9 that is transmission-connected to the camshaft 7, and a rack 10 that meshes with all the gears. The rack 10 is arranged to extend forward and backward. A driving plate 11 is slidingly connected to the welding base plate 1. The driving plate 11 is provided with a push rod cylinder 12 that controls its forward and backward movement. The push rod cylinder 12 is provided on the welding base plate 1, and the rack 10 is provided on the driving plate 11.

[0021] Furthermore, the welding base plate 1 is provided with a linear guide rail 13 extending forward and backward, a linear slider (not shown) is slidably connected to the linear guide rail 13, and the driving plate 11 is provided on the linear slider.

[0022] Furthermore, the driving mechanism is arranged below the welding base plate 1 .

[0023] In this embodiment, two sets of first and second positioning blocks 4 and 5 are first used to pre-position the two rectangular tubes. Then, the cooperating pressing cam 8 and third positioning block 6 are used to pre-position the short square tube located between the two tubes before welding. When the pressing cam 8 is used for lateral clamping, the push rod cylinder 12 is operated to extend, causing the extended push rod to drive the drive plate 11 to translate, thereby driving the connected rack 10 to move. The camshaft 7 rotates through the gear rack transmission, which in turn drives the pressing cam 8 to rotate until the short square tube pre-positioned at the short square tube welding station 3 is laterally clamped, thereby achieving a clamping effect on all short square tubes simultaneously.

[0024] The linear guide rail 13 cooperates with the linear slider to provide a sliding guide for the driving plate 11 when it moves relative to the welding base plate 1 .

[0027] In this embodiment, the rotary clamping cylinder 14 is provided to perform a secondary reinforcement and positioning function on the rectangular tube that has been pre-positioned in the rectangular tube welding station 2 .

[0028] The welding tool involved in the utility model is convenient for clamping and positioning the workpiece by pre-setting a rectangular tube welding station for positioning the rectangular tube and a short square tube welding station for positioning the short square tube, and the corresponding mechanism is used to implement secondary fixation of the square tube so that the welding operation can be carried out smoothly.
