Description

Technical Field

[0001] The utility model relates to a welding device, in particular to an auxiliary welding device. Background Art

[0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel skeletons and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise and other fields. It is easy to rust, and generally requires rust removal, galvanizing or coating, and regular maintenance. The characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation. Therefore, it is particularly suitable for the construction of large-span, super-high and super-heavy buildings.

[0003] The existing welding device needs to place two workpieces to be welded opposite to each other for welding. For example, CN218556025U discloses a welding device for a steel structure. The device is first placed horizontally, and then the auxiliary parts to be welded are inserted from both sides of the two fixed grooves respectively, and the two auxiliary parts are aligned. The servo motor is started, and the servo motor drives the screw rod to rotate. Two linkage blocks are respectively threadedly connected on both sides of the screw rod. Two limit rods are respectively fixedly welded on the inner sides of the two linkage blocks, so that the two limit rods move inward until they are against the auxiliary parts and are fixed. The operator takes out the welding head inside the mounting block and performs welding operation on the auxiliary parts. The welding slag generated during the welding process is moved downward by starting the induced draft fan and accurately falls into the collection box. A fixed welding is provided on one side of the collection box to prevent the welding slag from entering the induced draft fan and causing damage to the induced draft fan. The induced draft fan can also cool the auxiliary parts and absorb and discharge the welding smoke, thereby reducing the cooling time of the auxiliary parts. The operator can take out the concentrated collected welding slag through the handle, which is highly practical.

[0004] Although the above-mentioned prior art can clamp the welded parts, when welding steel columns or special-shaped parts, the clamping effect is reduced due to the smooth surface of the cylinder and the complex shape of the special-shaped parts, which can easily cause the workpiece to move during welding, affecting the welding effect.

[0005] Therefore, the known auxiliary welding device structure has the above-mentioned inconveniences and problems. Utility Model Content

[0025] The present invention is further described below in conjunction with the embodiments and the accompanying drawings. Example

[0026] Please refer to Figure 1-5 The auxiliary welding device of the utility model includes a workbench 100, and a plurality of supporting legs 102 are fixedly connected at the four corners of the bottom of the workbench 100 for supporting. The upper ends of the workbench 100 are detachably connected with load-bearing blocks 101 on both sides, and the outsides of the load-bearing blocks 101 on both sides are fixedly connected with placement barrels 103. The workpieces on both sides that need to be welded are inserted into the placement barrels 103 on both sides and supported by the supporting legs 102.

[0027] The auxiliary welding device of the utility model has a mounting block 202 installed on the inner top of the barrels 103 placed on both sides, and the outer wall of the barrels 103 placed on both sides is provided with a symmetrical connecting groove 107, and the two ends of the mounting block 202 are detachably connected to multiple chains 203, and the multiple chains 203 pass through the connecting groove 107 and are connected to a sliding plate 204, and the sliding plate 204 is slidably connected to the upper end of the workbench 100, and the workbench 100 is located on both sides of the barrels 103 and is fixedly connected with mounting plates 106, and the outer wall of each mounting plate 106 is detachably connected to a first telescopic rod 208, and the telescopic end of each first telescopic rod 208 passes through the mounting plate 106 and is detachably connected to a U-shaped frame 2 06. The opening of each U-shaped frame 206 faces the chain 203. The interior of each U-shaped frame 206 is rotatably connected to a sprocket 207 meshing with the multiple chains 203. The first telescopic rod 208 is extended to push the U-shaped frame 206 to move toward the chain 203. The multiple chains 203 on both sides are moved inward through the sprocket 207, and the sliding plate 204 is slid on the workbench 100 until the multiple chains 203 on both sides are wrapped around the outer wall of the workpiece. By having the multiple chains 203 fit against the outer wall of the workpiece, the contact area can be increased, making the workpiece clamped more firmly. In addition, due to the softness of the chain 203, it can still fit the outer wall of the workpiece when facing a special-shaped workpiece.

[0028] It is worth noting that the above-mentioned U-shaped frame 206 and the first telescopic rod 208 are the driving mechanism in this embodiment, which includes but is not limited to the U-shaped frame 206 and the first telescopic rod 208. Any mechanism that can move the multiple chains 203 on both sides inward to fit the outer wall of the workpiece can be applied to this embodiment.

[0029] The auxiliary welding device of the utility model is designed to tighten the multiple chains 203 on both sides after they are attached to the outer wall of the workpiece to increase the clamping effect. In this embodiment, the workbench 100 is provided with through grooves 104 on both sides of the barrels 103 on both sides, and sliding grooves 105 are provided on both sides of the inner part of each through groove 104. Each sliding plate 204 is slidably connected to the inside of each sliding groove 105. Each sliding plate 204 is fixedly connected with a return spring 205 on both sides of the outer wall close to the chain 203. Each return spring 205 is connected to the inner end of the sliding groove 105. When the pushing mechanism pushes the multiple chains 203 on both sides to move inward, each sliding plate 204 moves in the direction of the chain 203 inside the sliding groove 105, thereby compressing the return springs 205 on both sides. The chain 203 is always in a tightened state through the resilience of the return spring 205, thereby achieving a better clamping effect on the workpiece.

[0030] The auxiliary welding device of the utility model, in order to make the contact surface of the multiple chains 203 on both sides larger when they are attached to the outer wall of the workpiece through the pushing mechanism, in this embodiment, the outer walls of the barrels 103 on both sides are provided with connecting holes 108 near the upper ends, and the upper parts of the barrels 103 on both sides are provided with mounting top plates 200, and the bottom four corners of the mounting top plates 200 on both sides are fixedly connected with connecting vertical plates 201 which are detachably connected to the upper end of the workbench 100, and the upper end of the mounting top plates 200 is detachably connected with a second telescopic rod 209, and the telescopic end of the second telescopic rod 209 passes through the mounting top plates 200 and the connecting holes 108 and is connected to the mounting top plates 200. The upper end of the mounting block 202 is detachably connected, and the mounting block 202 is moved up and down by extending and retracting the second telescopic rod 209, so that the height of the mounting block 202 can be adjusted according to the size of the workpiece. When the workpiece is small, the mounting block 202 is lowered, and the chain 203 is pushed to fit the outer wall of the workpiece with the pushing device, so that the contact area can be further increased. When the workpiece is large, raising the mounting block 202 can also increase the fitting area, making the clamping more stable. In addition, by pressing the mounting block 202 on the upper end of the workpiece and cooperating with the load-bearing block 101 at the bottom, the stability of the workpiece during welding can be further increased.

[0031] It is worth noting that the second telescopic rod 209 is an adjustment mechanism of this embodiment. The adjustment mechanism includes but is not limited to the second telescopic rod 209. Any mechanism that can make the mounting block 202 rise or fall can be applied to this embodiment.

[0032] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
