It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] It should be noted that in the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

[0030] This embodiment provides a welding line for frame-type components, which is used to align and clamp a plurality of rods, and uses a welding robot 100 for welding, thereby reducing labor input, reducing the labor intensity of operators, and improving welding efficiency.

[0031] like Figure 1-5As shown, an embodiment of the utility model provides a frame welding line, including a welding robot 100, and a welding tool 200 is also arranged beside the welding robot 100. The welding tool 200 is used to position and clamp a plurality of rods to facilitate welding by the welding robot 100. In this embodiment, the welding tool 200 includes a welding plate 201 and a pressing device 210. The welding plate 201 is used to carry the rods to be welded, wherein a plurality of mutually staggered slideways 202 are arranged on the welding plate 201 in the transverse and longitudinal directions; the pressing device 210 includes a plurality of slideways 202, so that the plurality of rods can be fixed respectively, and movably connected in the slideway 202, so as to clamp the workpiece to be welded on the welding plate 201. In this embodiment, the pressing device 210 is slidably arranged in the slideway 202, so that it can move along the direction of the slideway 202, and adjust the relative position of the pressing device 210, so that the rods with different position requirements can be clamped and fixed, such as Figure 3-5 As shown, the pressing device 210 includes a base 211 and a pressing fixture 212, wherein the base 211 is movably connected within the slide 202, and the pressing fixture 212 is fixedly installed on the base 211, including a clamping arm 2121 and a toggle rod 2122 for driving the clamping arm 2121 to press down or release.

[0032] During the process of clamping and fixing the rods, multiple rods are arranged according to the established requirements. At this time, it is worth mentioning that the pressing device 210 slides along the slide 202 according to the requirements of the rod position, so as to move to a position suitable for the rod, so as to clamp and position the rod. When clamping the rod, the toggle rod 2122 swings to press a section of the clamping arm 2121 downward, thereby pressing the rod onto the welding plate 201. The rod is positioned by this device, thereby avoiding the operator's manual alignment, reducing the labor intensity of manual labor, and improving the efficiency of welding.

[0033] In this embodiment, the base 211 includes a connecting plate 2112 and a body 2111 formed on the connecting plate 2112. A movable groove 2113 corresponding to the slideway 202 is provided on the connecting plate 2112. The fastener passes through the movable groove 2113 and is fixedly connected to the slideway 202. In other words, after passing through the movable groove 2113, the fastener is fixed in the slideway 202. At this time, the fastener can be limitedly moved in the movable groove 2113, and then the relative positions of the base 211 and the pressing fixture 212 can be adjusted to adapt to rods with different position requirements.

[0034] In this embodiment, the welding plate 201 is formed by splicing a plurality of horizontally and vertically arranged crossbeams 204, and the slideways 202 are respectively provided on the crossbeams 204. The welding plate 201 is formed by butting and fixing a plurality of crossbeams 204 to each other, and is used to carry the rods to be welded. Since there are spaces between the crossbeams 204, when welding the rods, the execution end of the welding robot 100 can penetrate into the spaces between the crossbeams 204 to weld the sides of the rods, thereby improving the welding quality.

[0035] In this embodiment, the welding tool 200 is also provided with a flipping positioner, and the welding plate 201 is installed on the positioner and can be flipped under the drive of the positioner, that is, the clamped rod is facing the downward direction. At this time, it is convenient for the welding robot 100 to weld the lower part of the side of the rod, which can increase the welding points of the rod and improve the quality of welding.

[0036] In this embodiment, the pressing fixture 212 includes a base 213. Figure 5 As shown, the base 213 is fixedly installed on the base 211, one end of the toggle rod 2122 is rotatably connected to the base 213, and the other end thereof extends upward to form a gripping end 2123; one end of the clamping arm 2121 is rotatably connected to the base 213, and the other end thereof extends toward the outside of the base 213 and is provided with a clamping member 2124; the pressing clamp 212 also includes a connecting rod 2125, the upper end of the connecting rod 2125 is rotatably connected to the middle section of the toggle rod 2122, and the lower end is rotatably connected to the middle section of the clamping arm 2121.

[0037] When the gripping end 2123 is pushed to rotate the toggle rod 2122, the connecting rod 2125 pulls up the clamping arm 2121, so that the clamping member 2124 can swing upward. At this time, the gap between the clamping member 2124 and the welding plate 201 or the rod can be increased, which is convenient for placing the rod or removing the welded frame workpiece.

[0038] In this embodiment, the clamping member 2124 is a rod structure component, and a protrusion is provided at the end to increase the contact surface with the rod to ensure stability.

[0039] In this embodiment, if Figure 4-5As shown, a pressing block 2126 is formed on the connecting rod 2125. When the toggle rod 2122 swings toward the clamping arm 2121, the pressing block 2126 abuts against the clamping arm 2121. When the toggle rod 2122 swings downward, the clamping arm 2121 swings downward through the connecting rod 2125, so that the clamping member 2124 presses the rod below. At this time, in order to increase the pressing force on the clamping arm 2121, when the connecting rod 2125 drives the clamping arm 2121 to swing downward, as the toggle rod 2122 swings, the pressing block 2126 on the connecting rod 2125 abuts against the side of the clamping arm 2121, thereby applying downward pressure to the clamping arm 2121, so that the clamping arm 2121 can quickly swing downward under the push of the toggle rod 2122 and clamp the rod.

[0040] It is worth mentioning that the length of the connecting rod 2125 and the position of the rotational connection between the toggle rod 2122 and the clamping arm 2121 are set and adjusted in advance. When the toggle rod 2122 and the connecting rod 2125 are in the same straight line, the clamping arm 2121 clamps the rod. At this time, the toggle rod 2122 and the connecting rod 2125 are in the dead point position, so that the rod can be clamped stably and the dead point can be used to prevent the rod from being loosened.

[0041] In this embodiment, the base 213 includes a bottom plate 2131 and a vertical plate 2132 formed on the bottom plate 2131. The bottom plate 2131 is fixedly connected to the base 211. The clamping arm 2121 and the toggle rod 2122 are rotatably connected to the vertical plate 2132, and the rotation axis of the clamping arm 2121 is located on the upper side of the rotation axis of the toggle rod 2122. A vertical plate 2132 is provided on the base 213, so that the clamping arm 2121 and the toggle rod 2122 can be conveniently and quickly rotatably connected to the vertical plate 2132.

[0042] Meanwhile, the top of the vertical plate 2132 is set as an inclined surface with one end higher than the other end, the clamping arm 2121 is rotatably connected to the high end side of the vertical plate 2132, and the toggle rod 2122 is rotatably connected to the low end side of the vertical plate 2132. The height difference between the clamping arm 2121 and the toggle rod 2122 can make it easier to drive the clamping arm 2121 to flip, and make the clamping force of the clamping arm 2121 greater, thereby improving the stability of clamping the rod.

[0043] A frame welding line provided in the present embodiment clamps and fixes the rods to be welded after they are aligned with each other through a pressing device 210, so that it is convenient for the welding robot 100 to perform welding processing on them. In the process of clamping the rods, the toggle rod 2122 drives the clamping arm 2121 to swing through the connecting rod 2125. When the toggle rod 2122 is in a vertical state and is located on the same straight line as the connecting rod 2125, the clamping member 2124 clamps the rod. The toggle rod 2122 and the connecting rod 2125 are in a dead point position, thereby ensuring that the rod remains stable and facilitating welding. The welding line provided in the present embodiment can complete the positioning and fixing of the rods, reduce the alignment and holding work of the operator, reduce labor intensity, and perform welding through the welding robot 100, thereby improving welding efficiency.

[0044] For those skilled in the art, various other corresponding changes and deformations can be obtained according to the structure and principle disclosed by the utility model, and all of these changes and deformations belong to the protection scope of the utility model.
