Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] For an example, please refer to... Figures 1-4A steel truss welding device includes a drive mechanism 1, a base 4 mounted on the drive mechanism 1, a connecting mechanism 3 connected to the base 4, and a welding gun body 2 connected to the connecting mechanism 3. The connecting mechanism 3 includes a connector connected to the base 4, a connecting seat 305 connected to the connector, a connecting shaft 306 connected to the connecting seat 305, and a support frame 310 rotatably connected to one end of the connecting shaft 306 via a bearing. The welding gun body 2 is inserted into the support frame 310. The connecting seat 305 has several through holes 308. The support frame 310 has a threaded hole, and a second hand-tightening bolt 309 is threadedly connected to the threaded hole. The second hand-tightening bolt 309 is inserted into the inner wall of one of the through holes 308. The connecting seat 305, the connecting shaft 306 and the support frame 310 provide support for the welding gun body 2. The support frame 310 can rotate around the connecting shaft 306 and is fixed in position by the through hole 308 and the second hand-tightening bolt 309, thereby facilitating the adjustment of the angle of the welding gun body 2 and improving the flexibility of this application.

[0030] Furthermore, the support frame 310 is threaded with a fastening bolt 311. The end of the fastening bolt 311 extends into the support frame 310 and contacts the welding gun body 2. The welding gun body 2 can be fixed to the fastening bolt 311 by the fastening bolt 311. After unscrewing the fastening bolt 311, the welding gun body 2 can be removed by pulling it.

[0031] Furthermore, the connector includes a first connecting rod 301 connected to the base 4 by bolts. A second connecting rod 302 is fixedly connected to the end of the first connecting rod 301 away from the base 4. Two clamping plates 303 are held on the outer surface of the second connecting rod 302. Both clamping plates 303 are fixedly installed at the bottom of the connecting seat 305. The first hand-tightening bolt 304 and the clamping plates 303 cooperate to fix the connecting seat 305 on the second connecting rod 302. After loosening the first hand-tightening bolt 304, the connecting seat 305 can be rotated around the second connecting rod 302, thereby causing the welding gun body 2 to rotate around the second connecting rod 302, thus allowing the angle of the welding gun body 2 to be adjusted.

[0032] Furthermore, a first hand-tightening bolt 304 is provided between the two clamping plates 303. The clamping plate 303 near the head of the first hand-tightening bolt 304 is interlocked with the first hand-tightening bolt 304, and the other clamping plate 303 is threadedly connected to the outer surface of the first hand-tightening bolt 304, so that when the first hand-tightening bolt 304 is rotated, the two clamping plates 303 can be clamped on the second connecting rod 302 or released from the clamping state.

[0033] Furthermore, the drive mechanism 1 includes a drive component connected to the base 4, which is used to drive the base 4 to move up and down and horizontally, and then drive the welding gun body 2 to move through the connecting mechanism 3 to adjust the position of the welding gun body 2.

[0034] Furthermore, the driving component includes a horizontal hydraulic cylinder 105, the piston rod of which is connected to a second L-shaped connecting plate 106. The second L-shaped connecting plate 106 is fixedly connected to the base 4. The horizontal hydraulic cylinder 105 can drive the base 4 to move horizontally through the second L-shaped connecting plate 106, thereby driving the welding gun body 2 to move horizontally.

[0035] Furthermore, a lifting hydraulic cylinder 103 is provided above the horizontal hydraulic cylinder 105. The piston rod of the lifting hydraulic cylinder 103 is connected to a first L-shaped connecting plate 104. The bottom of the first L-shaped connecting plate 104 is connected to the top of the horizontal hydraulic cylinder 105. The lifting hydraulic cylinder 103 can drive the horizontal hydraulic cylinder 105 to move up and down through the first L-shaped connecting plate 104, thereby driving the welding gun body 2 to move up and down.

[0036] Furthermore, both the lifting hydraulic cylinder 103 and the horizontal hydraulic cylinder 105 are connected to slide rails 107 on their sides. The outer surfaces of the two slide rails 107 are slidably connected to slide blocks 108. The two slide blocks 108 are respectively connected to the first L-shaped connecting plate 104 and the second L-shaped connecting plate 106. The slide rails 107 and the slide blocks 108 limit the first L-shaped connecting plate 104 and the second L-shaped connecting plate 106 to improve the stability of the first L-shaped connecting plate 104 and the second L-shaped connecting plate 106 when they move horizontally.

[0037] Furthermore, a support member is provided on the side of the lifting hydraulic cylinder 103, which can support the lifting hydraulic cylinder 103.

[0038] Furthermore, the support includes a support plate 102 installed on the side of the lifting hydraulic cylinder 103. The bottom end of the support plate 102 is fixedly connected to a base plate 101. The base plate 101 is provided with several mounting holes. The base plate 101 and the support plate 102 cooperate with each other to support the lifting hydraulic cylinder 103.

[0039] The usage process of the steel truss welding device provided by this utility model is as follows:

[0040] After unscrewing the second hand-tightening bolt 309, rotate the support frame 310 around the connecting shaft 306, aligning the threaded hole on the support frame 310 with the corresponding through hole 308. Then, pass the second hand-tightening bolt 309 through the through hole 308 and connect it to the threaded hole to adjust the angle of the welding gun body 2. After loosening the first hand-tightening bolt 304, rotate the support frame 310 and the welding gun body 2 around the second connecting rod 302 to further adjust the angle of the welding gun body 2. After adjustment, tighten the first hand-tightening bolt 304. The lifting hydraulic cylinder 103 drives the horizontal hydraulic cylinder 105 to move up and down through the first L-shaped connecting plate 104, thereby driving the welding gun body 2 to move up and down. The horizontal hydraulic cylinder 105 drives the base 4 to move horizontally through the second L-shaped connecting plate 106, thereby driving the welding gun body 2 to move horizontally, so that the welding gun body 2 is aligned with the welding area for welding.
