[0022] A welding fixture for railings includes two bases 1, with a rotating frame 2 positioned between them.

A drive motor 4 for driving the rotating frame 2 is fixedly connected to one side of one of the bases 1, and the output end of the drive motor 4 is connected to the rotating shaft 3. Parallel first fixing rods 5, 6, 7, and 8 are fixedly connected to one side surface of the rotating frame 2. Multiple first fixing rods 5 and 8 are fixedly connected to the side walls of the first fixing rods 5 and 8 to define the positions of the upper and lower crossbars 91 and 92 of the railing 9. The positioning block 10 has two ends of the fourth fixing rod 8 fixedly connected to a second positioning block 11 for defining the positions of the left support rod 93 and the right support rod 94 of the railing 9; the surfaces of the second fixing rod 6 and the third fixing rod 7 are fixedly connected to a positioning crossbar 12 for defining the position of the vertical bar 95 of the railing 9; the first fixing rod 5, the second fixing rod 6, the third fixing rod 7 and the fourth fixing rod 8 are fixedly connected to a first pressing mechanism 13 for pressing the upper crossbar 91, the lower crossbar 92, the left support rod 93 and the right support rod 94 of the railing 9; the rotating frame 2 is fixedly connected to a plurality of second pressing mechanisms 14 for pressing the vertical bar 95 of the railing 9.

[0023] This invention, through the cooperation of the base 1, rotating frame 2, rotating shaft 3, and drive motor 4, enables the railing 9 to rotate at multiple angles during the welding process, facilitating welding at different positions, improving welding convenience and flexibility, and ensuring the accuracy of the welding position. By setting up the first positioning block 10, the second positioning block 11, the positioning crossbar 12, the first clamping mechanism 13, and the second clamping mechanism 14, a stable installation and positioning foundation is provided for each component of the railing, preventing displacement of these components during welding, ensuring the fixed position of the components during welding, and improving welding quality.

[0024] Furthermore, in another embodiment, the top of the first positioning block 10 is fixedly connected to a first positioning plate 101 that abuts against the side wall of the upper crossbar 91 or the lower crossbar 92.

[0025] By setting the first positioning block 10, the upper crossbar 91 and the lower crossbar 92 are respectively placed on the top of the first positioning block 10, and the first positioning plate 101 on the first positioning block 10 abuts against the side wall of the upper crossbar 91 or the lower crossbar 92, which can effectively limit the installation position of the upper crossbar 91 or the lower crossbar 92, thereby ensuring that the upper crossbar 91 or the lower crossbar 92 maintains an accurate installation posture during welding.

[0026] Furthermore, in another embodiment, the top of the second positioning block 11 is fixedly connected to a second positioning plate 111 that abuts against the side walls of the left support rod 93 and the right support rod 94.

[0027] By setting a second positioning block 11, the second positioning plate 111 at the top of the second positioning block 11 abuts against the side wall of the left support rod 93 or the right support rod 94, which can effectively limit the installation position of the left support rod 93 or the right support rod 94, thereby ensuring that the left support rod 93 or the right support rod 94 maintains an accurate installation posture during welding.

[0028] Furthermore, in another embodiment, the surface of the positioning crossbar 12 is provided with a plurality of limiting grooves 121 for placing the longitudinal bar 95 and which are evenly distributed at equal intervals.

[0029] By setting two positioning crossbars 12, the limiting grooves 121 evenly distributed at equal intervals on the surface of the positioning crossbars 12 are used to place the longitudinal bars 95, providing a precise installation position for the longitudinal bars 95, ensuring the uniformity and consistency of the arrangement of the longitudinal bars 95, and facilitating the rapid installation and positioning of the longitudinal bars.

[0030] Furthermore, in another embodiment, the first clamping mechanism 13 includes a rib clamp 131, on which a first clamping block 132 in the shape of an inverted L is provided, and a shim block 133 is fixedly connected to the bottom of the rib clamp 131.

[0031] Furthermore, in another embodiment, the second pressing mechanism 14 includes a cylinder 141, the telescopic end of the cylinder 141 is fixedly connected to a pressure plate 142, and the bottom ends of the pressure plate 142 are respectively fixedly connected to second pressing blocks 143.

[0032] By setting a second pressing mechanism 14, the inverted L-shaped first pressing block 142 on the rib clamp 141 of the second pressing mechanism 14 can press the upper horizontal bar 91, lower horizontal bar 92, left support bar 93 and right support bar 94 of the railing 9, effectively preventing the components from loosening during the welding process.

[0033] By setting a second pressing mechanism 14, the cylinder 141 of the second pressing mechanism 14 drives the pressure plate 142 to move. The second pressing blocks 143 at both ends of the pressure plate 142 can simultaneously press the two longitudinal rods 95 to ensure that the longitudinal rods 95 are in a stable position during the welding process.

[0034] The working principle of one embodiment of this utility model is as follows:

[0035] First, place the upper horizontal bar 91 and lower horizontal bar 92 of the railing 9 between the first positioning blocks 10, with the first positioning blocks 10 defining their positions. Then, place the left support rod 93 and right support rod 94 vertically in front of each fixed rod 8, with the positions of the left support rod 93 and right support rod 94 determined by the second positioning block 11. Next, place the vertical bar 95 into the limiting groove 121 of the positioning horizontal bar 12, completing the positioning of the vertical bar 95 through the limiting groove 121, ensuring that all components of the railing 9 abut against each other during installation. After positioning, activate the first clamping mechanism 13, using the first clamping block 132 on the rib clamp 131 to clamp and fix the upper horizontal bar 91, lower horizontal bar 92, left support rod 93, and right support rod 94. Simultaneously, activate the second clamping mechanism 14, using the cylinder 141 to push the pressure plate 142, causing the second clamping blocks 143 at both ends to clamp the vertical bar 95, thus completing the installation and fixation of all components of the railing 9 on the fixture, preparing for subsequent welding work.
