The angle iron truss includes two angle irons 100 and a tooth-shaped steel bar 200 welded between the two angle irons 100.

[0053] The angle iron truss welding device includes a rack 10, a guide and limiting mechanism 20, a positioning and clamping mechanism 30 and a welding mechanism. The rack 10 serves as a support, and a conveying channel is formed on the rack 10, and the angle iron 100 and the tooth-shaped steel bar 200 can move along the conveying channel. The guide and limiting mechanism 20 is arranged on both sides of the conveying channel and is used for guiding and limiting the angle iron truss. The positioning and clamping mechanism 30 is used for clamping the angle iron 100 and the tooth-shaped steel bar 200 to prevent displacement during welding. The welding mechanism includes two welding main machines 40 distributed on both sides of the conveying channel and used for welding the angle iron 100 and the tooth-shaped steel bar 200.

[0054] The following will be described in detail.

[0055] The guide and limiting mechanism 20 includes guide wheels 21 and limiting wheels 22. The guide wheels 21 are used for supporting the outer sides of the angle irons 100, and the limiting wheels 22 are used for limiting the distance between the inner sides of the angle irons 100 and the tooth-shaped steel bar 200. Through the cooperation of the guide wheels 21 and the limiting wheels 22, the angle irons 100 and the tooth-shaped steel bar 200 can smoothly advance along the conveying channel. The guide and limiting mechanism 20 can ensure that the relative position between the angle irons 100 and the tooth-shaped steel bar 200 does not change, the angle irons 100 on both sides remain parallel and linearly advance, and the tooth-shaped steel bar 200 advances synchronously with the angle irons 100 on both sides.

[0058] Specifically, the guide wheel 21 is arranged on the guide frame 23, and the position of the guide frame 23 is adjustable.

[0059] The limiting wheel 22 comprises a second support shaft and a second wheel body rotatably arranged on the second support shaft, and a limiting protrusion is arranged on the second wheel body in a circumferential direction, and the limiting protrusion can be inserted between the angle iron 100 and the deformed steel bar 200.

[0065] Since the bottom of the angle iron 100 is supported by the supporting wheel and the top of the angle iron 100 is pressed by the steel bar guide strip 31, the clamping of the angle iron 100 is realized. Since one side of the deformed steel bar 200 abuts against the steel bar guide strip 31 and the other side of the deformed steel bar 200 abuts against the pressing seat 32, the clamping of the deformed steel bar 200 is realized.

[0066] Specifically, the positioning and clamping mechanism 30 comprises a downward pressing cylinder 33, the output end of the downward pressing cylinder 33 is connected with the steel bar guide strip 31, and the downward pressing cylinder 33 can drive the steel bar guide strip 31 to move in the vertical direction.

[0070] The end of the pressing seat 32 is provided with a pressing bearing 37, which presses the deformed steel bar 200, and since the pressing bearing 37 is rotatable, it can be automatically adjusted to a certain extent when pressing the deformed steel bar 200, so as to ensure close contact; since the pressing bearing 37 is cylindrical, it can match the curvature of the deformed steel bar 200 and increase the contact area.

[0071] The positioning and clamping mechanism 30 comprises a positioning seat 38, the pressing shaft 35 is rotatably arranged on the positioning seat 38 through a bearing. The positioning seat 38 is connected with the pressing cylinder 33 and plays a supporting role.

[0072] The position of the positioning and clamping mechanism 30 is adjustable. It can be adjusted by two or three mutually perpendicular guide rails.
