[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] A positioning device for welding wire butt welding, such as Figures 1-5 As shown, it includes a support base 1; the support base 1 is provided with a correction mechanism 3; the correction mechanism 3 can perform correction operations on the welding materials, so that the materials on both sides extend to the same length, avoiding the support structure from blocking the welding rod due to the materials extending too short.

[0030] Specifically, the correction mechanism 3 includes a support frame 301, which is rotatably connected to one side of the top of the support base 1. A baffle 302 is rotatably connected to the bottom side of the support frame 301, and the length of the baffle 302 is half the height of the support frame 301. A connecting rod 303 is rotatably connected to the outside of the baffle 302, and a counterweight 304 is rotatably connected to the end of the connecting rod 303. The counterweight 304 is slidably connected to the bottom of the support frame 301. The bottom of the support frame 301 is an inclined structure with an inclination angle of less than 45°. When the support frame 301 is placed horizontally, the counterweight 304 can slide away from the baffle 302 along the inclination direction, thereby opening the baffle 302 through the connecting rod 303. When the rotation angle of the support frame 301 is greater than the inclination angle of the bottom of the support frame 301, the counterweight 304 can slide closer to the baffle 302 along the inclination direction, and close the support frame 301 through the baffle 302.

[0031] Furthermore, the support frame 301 has a bearing hole 305 in the middle, which can support the material to be butt-welded. The bearing hole 305 is a round hole. The support frame 301 has a "U"-shaped structure, which can provide two support points for the material to be butt-welded, thereby improving the stability of the material. A support rod 306 is fixedly connected to the support frame 301. A sliding groove 307 corresponding to the structure of the support rod 306 is opened on the inner side of the support base 1. The structure of the support rod 306 can cooperate with the sliding groove 307 to position the support frame 301, so that the support frame 301 can slide inside the support base 1. At the same time, the sliding groove 307 is composed of horizontal and arc-shaped splicing, so that the support frame 301 can rotate from the inclined position along the arc-shaped sliding groove 307 into the support base 1, and move horizontally inside the support base 1 along the horizontal sliding groove 307.

[0032] In addition, a second connecting rod 308 is rotatably connected to the side of the support frame 301, and a drive rod 309 is rotatably connected to the end of the second connecting rod 308. A drive plate 310 is rotatably connected to the end of the drive rod 309. The second connecting rod 308 can drive the two support frames 301 at the same time, so that the support frame 301 and the welding material on the support frame 301 move towards each other, thereby facilitating the subsequent welding operation.

[0033] Based on this, a storage groove 311 is provided at the bottom of the support frame 301. A positioning rod 312 is rotatably connected inside the storage groove 311. An anti-slip pad is fixedly connected to the end of the positioning rod 312. The structure of the storage groove 311 can store the positioning rod 312. When the support frame 301 is rotated to correct the raw materials, the positioning rod 312 can support the rotated support frame 301 so that the support frame 301 can maintain the set angle.

[0034] Example 2

[0035] likeFigures 1-6 As shown, based on Embodiment 1, the support base 1 is provided with an adjustment mechanism 2; the adjustment mechanism 2 can adjust the angle of the welding material, so that the two materials can be rotated at the same time during the welding process, which facilitates welding operations on different welding points without affecting the welding point.

[0036] In this embodiment, the adjusting mechanism 2 includes a toothed ring 201, which is rotatably connected to the inner side of the support frame 301. The toothed ring 201 can support the raw material and drive the raw material to rotate within the support frame 301. A drive screw 202 is fixedly and rotatably connected to the toothed ring 201, and a clamping block 203 is engaged with the drive screw 202. The drive screw 202 can drive the clamping block 203 to move, thereby clamping and securing the raw material using the clamping block 203.

[0037] Furthermore, a gear 204 is rotatably connected inside the support base 1. The gear 204 meshes with the gear ring 201, and the structure of the gear 204 can drive the gear ring 201. A sleeve rod 205 is fixedly connected to the inner side of the gear 204. A connecting rod 206 is connected between the sleeve rods 205. The connecting rod 206 and the sleeve rod 205 cooperate with each other, so that the gears 204 at both ends can rotate synchronously. At the same time, the connecting rod 206 is a non-cylindrical structure, and the inner structure of the sleeve rod 205 corresponds to the connecting rod 206. Therefore, the sleeve rod 205 can slide along the connecting rod 206 and drive the sleeve rod 205 when the connecting rod 206 rotates. A buffer spring 207 is connected between the connecting rod 206 and the sleeve rod 205. The buffer spring 207 can buffer the sleeve rod 205. When the gear 204 and the gear ring 201 are in a non-meshing state, the movement of the gear ring 201 can drive the gear 204 and the sleeve rod 205 to move and compress the buffer spring 207. After the gear 204 rotates to the meshing state, the gear 204 moves outward under the elastic action of the buffer spring 207 and meshes with the gear ring 201.

[0038] Furthermore, a drive frame is fixedly connected to the outer side of gear 204, and the drive frame structure can drive gear 204. A drive handle 313 is rotatably connected to the top of drive plate 310, and the drive handle 313 structure can drive drive plate 310 and two connecting rods 308, so that support base 1 can move synchronously in opposite directions. A limit frame 314 is rotatably connected to the top of support base 1, and the limit frame 314 structure can limit support frame 301, so that support frame 301 is prevented from rotating when driven by connecting rods 308.

[0039] In use, the positioning device for welding wire of this utility model first rotates the support frame 301 inward around the connecting rod 308 at the end until the rotation angle is greater than the inclination of the bottom of the support frame 301. Then, the positioning rod 312 is rotated out from the storage groove 311 and used to support and position the tilted support frame 301. After the support frame 301 is tilted, since the bottom of the support frame 301 is tilted towards the middle of the support base 1, the counterweight 304 at the bottom of the support frame 301 slides from the middle of the support frame 301 towards the edge of the support frame 301, and pushes the baffle 302 to rotate towards the support frame 301 through the connecting rod 303. Then, the raw material is placed into the bearing hole 305 on the inner side of the support frame 301. The raw material slides down along the tilted bearing hole 305 until the end contacts the baffle 302, and the baffle 302 then positions the raw material. Because the diameter of the raw material is similar to that of the bearing hole 305, the contact point between the raw material and the baffle 302 is the edge of the baffle 302 near the end of the raw material. Since this contact point is close to the hinge point of the baffle 302, the force arm of the raw material pushing the baffle 302 is less than the force arm of the connecting rod 303 driving the baffle 302. Therefore, the rotation amplitude of the raw material driving the baffle 302 is relatively small. The raw material extends a set length from the support frame 301 under the constraint of the baffle 302. Then, the clamping block 203 is driven by the drive screw 202 to clamp and fix the raw material inside the toothed ring 201. The positioning rod 312 is then retracted into the receiving groove 311, and the support frame 301 is rotated back to its original position. The limiting frame 314 is then rotated to close the top of the support frame 301. The drive rod 309 is moved downwards by the drive plate 310, and the support frames 301 on both sides are moved towards each other by the connecting rod 308, causing the raw materials to move closer together for welding. During the welding process, the gear 204 driven by the drive frame can drive the gear ring 201, thereby keeping both ends of the material rotating synchronously, and thus performing welding operations on the material at different angles.
