Description

Technical Field

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

[0002] When welding, it is usually necessary to position the main body and accessories first to ensure that their relative positions meet the requirements before welding to obtain the desired welding effect.

[0003] When welding some main bodies with openings, it is necessary to place the accessories in the openings, and then weld the gap formed by the accessories and the openings. In this case, the accessories need to be positioned first to ensure that the accessories are at the same height as the openings throughout the process to avoid unevenness after welding, which affects the quality. In the prior art, the accessories are usually installed on a positioning bracket, and the positioning bracket is placed on the main body. After adjusting to a suitable position, welding is performed. This method is only suitable for welding some flat main bodies. For some main bodies with uneven surfaces, raised structures, and irregular shapes, due to the height difference on the surface of the main body, it is impossible to effectively ensure that the main body and the accessories are at the same height during welding, resulting in poor positioning effect, which greatly reduces the welding accuracy. Moreover, the surface of such main bodies is uneven, and the positioning bracket is prone to shaking after being placed, and it is difficult to install the positioning bracket stably, which may cause the accessories to tip over or deflect during welding, resulting in low final welding accuracy and poor welding effect. Utility Model Content

[0004] In view of this, in order to solve the problems existing when welding some bodies with uneven surfaces or irregular shapes, the utility model provides a simple welding positioning device.

The positioning part is provided with a first threaded hole. A first adjusting part is threadedly connected to the first threaded hole. The magnet is connected to one end of the connecting part.

[0006] In the above technical solution, an opening is provided on the first target part. After the second target part is placed in the opening, a circle of weld is formed between its edge and the opening, and the first target part is connected to the second target part by welding the weld; the positioning block is composed of a connecting part, and a plurality of positioning parts connected to the side of the connecting part with the connecting part as the center, one end of the positioning part is connected to the connecting part, and a certain angle is maintained between adjacent positioning parts, and a first threaded hole is provided at one end of each positioning part away from the connecting part, and a first adjusting part is penetrated in the first threaded hole, and the bottom of the first adjusting part is directly placed on the first target part during welding. , used for support, the first adjusting piece is threadedly connected to the first threaded hole, and the height can be adjusted by rotating the first adjusting piece. The magnet is located at the bottom of the positioning block, wherein the magnet is an electromagnet, and the presence or absence of magnetism can be adjusted by controlling the charged state. When welding, the second target piece is adsorbed on the bottom of the magnet under the magnetic force of the magnet, and then the welding positioning device is placed on the first target piece.

When targeting some first target parts with uneven and irregular surfaces, the height of the first adjusting part of each positioning part is adjusted separately. Therefore, the height of the first target part and the second target part can be ensured to be the same during welding, thereby avoiding the uneven heights of the first target part and the second target part due to tipping or displacement of the second target part, effectively improving the welding accuracy, and the overall structure is simple and easy to use and operate. At the same time, the second target part can be kept stable during the welding process, thereby ensuring the positioning effect and improving reliability.

[0033] Please refer to Figures 1 to 3 The present embodiment provides a simple welding positioning device, which is used for positioning a first target part 4 and a second target part 5 during welding. The first target part 4 is provided with an opening 41 that matches the second target part 5. The welding positioning device includes a positioning block 1 and a magnet 2. The positioning block 1 includes a connecting portion 12 and a plurality of positioning portions 11 connected to the connecting portion 12. The plurality of positioning portions 11 are centered on the connecting portion 12 and are distributed around the outer side of the connecting portion 12 at intervals. A first threaded hole 111 is provided on the positioning portion 11. A first adjusting member 112 is threadedly connected to the first threaded hole 111. The magnet 2 is connected to one end of the connecting portion 12.

[0034] In this embodiment, an opening 41 is provided on the first target part 4. When welding, the second target part 5 is placed in the opening 41, and a circle of weld is formed between its edge and the opening 41. The first target part 4 is connected to the second target part 5 by welding the weld. The positioning block 1 is composed of a connecting part 12, and a plurality of positioning parts 11 connected to the side of the connecting part 12 with the connecting part 12 as the center. One end of the positioning part 11 is connected to the connecting part 12, and a certain angle is maintained between adjacent positioning parts 11. A first threaded hole 111 is provided at one end of each positioning part 11 away from the connecting part 12. A first adjusting member 112 is penetrated in the first threaded hole 111. When welding is performed, the bottom of the first adjusting member 112 is directly placed It is placed on the first target part 4 for support, the first adjusting part 112 is threadedly connected to the first threaded hole 111, and the height can be adjusted by rotating the first adjusting part 112. The magnet 2 is located at the bottom of the positioning block 1, wherein the magnet 2 is an electromagnet, and the presence or absence of magnetism can be adjusted by controlling the charged state. When welding, the second target part 5 is adsorbed on the bottom of the magnet 2 under the magnetic force of the magnet 2, and then the welding positioning device is placed on the first target part 4. The height and position of the second target part 5 are adjusted by adjusting the first adjusting parts 112 on the multiple positioning parts 11, so that the second target part 5 located in the opening 41 has the same height as the first target part 4, thereby ensuring the welding accuracy.

[0035] Please refer to Figure 3 , Figure 3 The surface of the first target part 4 is uneven, and there are some raised structures or recessed structures, which will produce a height difference on the surface where the welding positioning device is placed. In the present application, each positioning part 11 is threadedly connected with a first adjusting part 112, and the first adjusting parts 112 on different positioning parts 11 can be adjusted respectively. By changing the distance that the first adjusting part 112 extends out of the bottom of the positioning part 11, the height of the first target part 4 at this point can be adapted, so that the second target part 5 located below the positioning block 1 and connected to the magnet 2 can be flush with the height of the first target part 4 to ensure welding accuracy. At the same time, it can also ensure that the positioning block 1 can remain stable when placed on the first target part 4 to avoid shaking of the second target part 5 during welding, thereby ensuring the positioning effect and improving reliability.

[0036] Therefore, the present application is provided with a plurality of positioning parts 11, and the height is adjusted respectively by the first adjusting part 112 on each positioning part 11. For some first target parts 4 with uneven and irregular surfaces, by adjusting the height of the first adjusting part 112 of each positioning part 11 respectively, the height of the first target part 4 and the second target part 5 can be ensured to be the same during welding, thereby avoiding uneven heights of the first target part 4 and the second target part 5 due to tipping or displacement of the second target part 5, effectively improving the welding accuracy, and the overall structure is simple and easy to use and operate.

The magnet 2 is connected to the bottom end of the second adjusting member 122, and the second adjusting member 122 is threadedly connected to the second threaded hole 121. The height of the magnet 2 can be adjusted by rotating the second adjusting member 122, thereby adjusting the height of the second target member 5 adsorbed on the bottom of the magnet 2. During welding, after the first adjusting member 112 is adjusted and stabilized, the height of the second target member 5 can be further fine-tuned by the second adjusting member 122 to further ensure that the first target member 4 and the second target member 5 are at the same height and remain flush, thereby improving reliability.

Before welding, the control switch 3 is pressed to turn on the power supply device so that the magnet 2 is energized and has magnetism, and the second target part 5 is adsorbed. After the welding is completed, the control switch 3 is pressed to turn off the power supply device, so that the magnet 2 is powered off and loses its magnetism, thereby separating from the second target part 5. By setting the control switch 3, the welding positioning device is more convenient to use.
