The present embodiment provides a truss welding apparatus for welding a truss 100. As shown in fig. 1 and 2, the truss 100 includes a frame body 110 and a connection member 120. The frame body 110 includes an upper chord 111, a web member 112, and two lower chord 113. The upper chord ribs 111 are positioned above the two lower chord ribs 113, the web bar ribs 112 are wave-shaped, and the upper chord ribs 111 and each lower chord rib 113 are welded and connected through the web bar ribs 112, so that the cross section of the frame body 110 is triangular. The connecting member 120 is welded and fixed to the bottom of the lower chord 113, and is used for fixing with the wooden template. In this embodiment, the bottom of each lower chord rib 113 is provided with a plurality of connecting pieces 120 at intervals along the length direction, and the connecting pieces 120 at both sides are arranged at intervals along the arrangement direction of the two lower chord ribs 113, so that a plurality of trusses 100 can be conveniently stacked up and down, and a large amount of placing space is saved.

The truss welding apparatus in this embodiment is used for welding the frame body 110 and the connection member 120.

The front support plate 21 is used for supporting the frame body 110, and after the feeding mechanism 4 feeds the connecting member 120 onto the welding table 31, the top of the connecting member 120 can abut against the frame body 110, so that the connecting member 120 can be conveniently welded with the frame body 110.

Optionally, the support table further comprises a rear support plate 22, the front support plate 21 and the rear support plate 22 are spaced apart, the welding table 31 is located between the front support plate 21 and the rear support plate 22, and the front support plate 21 is higher than the rear support plate 22 and the height difference is equal to the height of the connecting member 120. The frame body 110 extends in the arrangement direction of the front support plate 21 and the rear support plate 22, that is, the X direction in fig. 3, a portion of the frame body 110 to which the connector 120 is not welded is located on the front support plate 21, and a portion of the frame body 110 to which the connector 120 is welded is located on the rear support plate 22, which helps to improve the stability of the frame body 110 and the truss 100.

During the operation of the truss welding equipment, the frame body 110 is intermittently conveyed along the X direction, after the welding mechanism 3 welds the connecting piece 120 on the welding table 31 and the frame body 110, the frame body 110 is conveyed along the X direction by a specified distance, and the feeding mechanism 4 conveys the connecting piece 120 to the welding table 31 so as to perform the next welding.

As shown in fig. 4, the number of the welding heads 32 is two, and the welding heads 32 are respectively located at two sides of the frame body 110 in the length direction, and each welding head 32 is respectively connected with the lifting assembly 33, so that the two welding heads 32 can respectively weld two lower chord ribs 113, thereby improving the processing efficiency.

In order to improve the position accuracy of the two connecting members 120 on the welding table 31, so as to improve the welding effect of the lower chord rib 113 and the corresponding connecting member 120, as shown in fig. 4, 5 and 8, a limiting protrusion 3111 is convexly disposed at the center of the welding table 31, the two feeding mechanisms 4 are respectively located at two opposite sides of the limiting protrusion 3111, and can respectively feed the connecting members 120 onto the welding table 31 along the Y direction and the opposite direction of the Y direction, so that the connecting members 120 can abut against the corresponding sides of the limiting protrusion 3111, thereby realizing the positioning of the connecting members 120 on the welding table 31, and helping to ensure the welding effect of the connecting members 120 and the frame body 110.

In this embodiment, the feeding mechanism 4 includes a material storage and conveying assembly 41, a material guide chute 42, a material receiving plate 43, and a material pushing assembly 44.

In the process that the pushing assembly 44 pushes the connecting piece 120 to the welding table 31, the pushing assembly 44 shields the discharge hole, so that the connecting piece 120 at the bottommost layer in the material guide groove 42 is prevented from falling, and the connecting pieces 120 are conveyed one by one. After the pushing assembly 44 is reset, the pushing assembly 44 does not block the discharge hole any more, and the connecting member 120 at the bottom of the material guiding groove 42 falls onto the material receiving plate 43 under the action of gravity for the next welding. In this embodiment, the two pushing assemblies respectively push the connecting member 120 in the Y direction and the opposite direction of the Y direction.

In this embodiment, the top surface of the receiving plate 43 is flush with the welding table 31, so that the pushing assembly 44 can smoothly push the connecting member 120 on the receiving plate 43 onto the welding table 31.

In some embodiments, the receiving plate 43 may extend obliquely downward from below the discharge hole to the welding table 31, so that the pushing assembly 44 can smoothly push the connecting member 120 on the receiving plate 43 onto the welding table 31.

Specifically, the pressing mechanism 5 includes a mounting frame 51, a pressing driving member 52 and a pressing head 53, the mounting frame 51 is disposed on the frame 1, the pressing driving member 52 is disposed on the mounting frame 51, the pressing head 53 is disposed at an output end of the pressing driving member 52, and the pressing head 53 can be driven by the pressing driving member 52 to be lifted and lowered so as to press the frame body 110 or be lifted downwards.

Optionally, the pressing head 53 has a pressing surface adapted to the upper end of the frame 110 to increase the contact area with the frame 110, which helps to improve the stability of the frame 110 when pressing down.

Alternatively, the push-down driving member 52, the lifting driving member 331, and the pushing material driving member 441 may be cylinders, hydraulic cylinders, linear motors, or the like, as long as they can output linear motion.

By adopting the truss welding equipment provided by the embodiment, the automatic feeding of the connecting piece 120 and the automatic welding of the connecting piece 120 and the frame body 110 can be realized, so that the labor cost is reduced, and the production efficiency is improved. After the truss 100 is welded, threaded holes are machined in the connecting pieces 120, so that the truss can be accurately connected with a wooden template, and the truss is convenient to disassemble and assemble.
