Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a seat frame welding device. Background Art

[0002] The seat includes a frame, and the seat frame will be designed during the actual production. Each manufacturer will weld and perform other operations on the seat frame based on the specific design and the actual needs of the production line to make it meet the needs of the seat frame product and the needs of the production line.

[0003] Prior art, such as the utility model patent document with authorization announcement number "CN187551637U" and patent name "A tooling fixture for welding a car seat frame", discloses a welding device, which includes a placing table, on which a clamping device and an adjusting device are arranged, the clamping device includes side panels, gaskets, springs, connecting plates, connecting rods, splints, and anti-slip pads, and clamping devices are symmetrically arranged at both ends of the top of the placing table, and side panels are symmetrically fixedly connected to both sides of the top of the placing table, and a gasket is symmetrically fixedly connected to one side of the side panel, and a spring is fixedly connected to the other side of the gasket, and a connecting plate is arranged at the other end of the spring, and the other end of the spring is fixedly connected to one side of the connecting plate.

[0004] In actual use, the above patent places the frame on the placement table, releases the finger pulling the handle, and the spring contracts to drive the connecting plate to move inward, so that the connecting rod pushes the clamping plate to slide inward, so that the frame is clamped. However, some existing seat back frames are narrow at the top and wide at the bottom, such as Figure 3 As shown, after these frames are placed on the placement table, although the two clamps can abut against the side walls of the frame to clamp the frame, the balance point of the frame cannot be found. Therefore, the frame is easy to loosen between the two clamps during welding, so that the position of the frame is easy to shift, the position during welding is inaccurate, and it is difficult to ensure the consistency of the product. Utility Model Content

[0005] In view of the deficiencies existing in the prior art, the utility model provides a seat frame welding device, which is used to solve the technical problem that the frames of some seat backs mentioned in the background technology are narrow at the top and wide at the bottom. Therefore, after these frames are placed on the placement table, although the two clamps can abut against the side walls of the frames to clamp the frames, the balance point of the frames cannot be found. Therefore, during welding, the frames are prone to loosen between the two clamps, so that the position of the frames is prone to shift, the position during welding is inaccurate, and it is difficult to ensure the consistency of the products.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0010] Start the welding robot, and the welding robot starts welding the skeleton body.

[0011] Beneficial effects:

[0012] In this solution, by setting two first support plates and four movable blocks that slide horizontally, the distance between the two sides of the skeleton body can be adjusted, so as to adapt to the placement of skeleton bodies of different specifications, which is highly practical;

[0013] By setting the first clamping block and the second clamping block, the first clamping block and the second clamping block on each movable block form a group of clamping components, and four groups of clamping components clamp the seat frame body. The four groups of clamping components firmly clamp the frame body, thereby avoiding the loosening of the frame body during welding and the displacement of the position of the frame body, thereby improving the consistency of the product.

[0021] In the present solution, by setting two first support plates 3 and four movable blocks 20 for horizontal sliding, the frame body 18 can be adjusted to accommodate frame bodies 18 of different specifications, which is highly practical. By setting the first clamping block 5 and the second clamping block 6, the first clamping block 5 and the second clamping block 6 on each movable block 20 form a group of clamping components, and the four groups of clamping components clamp the seat frame body 18. The four groups of clamping components firmly clamp the frame body 18, thereby avoiding the loosening of the frame body 18 during welding and the displacement of the position of the frame body 18, thereby improving the consistency of the product.

[0022] like Figure 1 to Figure 3As shown, two second support plates 4 are slidably connected to the first support plate 3, and the two first support plates 3 are provided with slide rails arranged along the length direction of the first support plate 3.

[0025] like Figure 2 As shown, the first clamping block 5 and the second clamping block 6 have arc-shaped end surfaces. The arc-shaped surface fits the arc surface of the frame body 18 better, further strengthening the clamping effect. Figure 1 to Figure 3As shown, a third plug-in block 15 is fixedly provided on the side wall of the second support plate 4, and the structure of the third plug-in block 15 is also consistent with that of the second plug-in block 10. A mounting groove is also provided on the third plug-in block 15, and the mounting groove is communicated with the outside. A fourth plug-in block 16 is fixedly provided on the side wall of the first support plate 3, and the structure of the fourth plug-in block 16 is also consistent with that of the second plug-in block 10.
