Description

Technical Field

[0001] This utility model belongs to the field of magnetic attraction device technology, and specifically relates to a novel magnetic attraction device for welded parts. Background Technology

[0002] Projection welding is a highly efficient welding method that can perform multi-point welding simultaneously. Projection welding is a resistance welding method in which one or more protrusions are pre-processed on the mating surface of one workpiece, so that they come into contact with the surface of another workpiece and are heated by electricity, and then collapsed, so that these contact points form a weld. Currently, a magnetic attraction structure is set on the projection welding device for nuts. That is, after the welding is completed, when the positioning plate under the welding head is raised, it will also take away the magnetically attracted nut.

[0003] Existing electromagnet rings used for magnetic attraction are generally embedded and fixed in a positioning plate that is pressed against the nut during welding. As the positioning plate descends and presses against the nut, the electromagnet ring also comes into contact with it. This type of installation makes the electromagnet ring prone to damage due to the impact force generated by frequent contact with the nut during projection welding. Therefore, a new type of magnetic attraction device for welded parts is needed to solve the problems existing in the prior art. Utility Model Content

[0011] Compared with the prior art, the novel magnetic attraction device for welded parts provided by this utility model has at least the following beneficial effects:

[0012] By using an anti-impact magnetic attraction mechanism, the elastic structure formed by the lifting sleeve and the second buffer spring on the positioning plate can reduce hard contact during the process of the electromagnet descending and contacting the nut.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Please see Figure 1-4 This utility model provides a novel magnetic attraction device for welding parts, including a welding device 1. The lifting mechanism of the welding device 1 is provided with a welding head 2 at its end. A positioning pressure plate 6 is provided below the welding head 2. An anti-impact magnetic attraction mechanism is provided on the surface of the positioning pressure plate 6. The anti-impact magnetic attraction mechanism includes a lifting sleeve 10, an electromagnet 12, and a second buffer spring 14. The lifting sleeve 10 is slidably connected to the positioning pressure plate 6. The second buffer spring 14 is sleeved on the outside of the lifting sleeve 10. The electromagnet 12 is provided inside the lifting sleeve 10. A spiral pattern 17 is provided on the upper part of the side surface of the lifting sleeve 10. An assembly knob 15 is threaded on the spiral pattern 17 of the lifting sleeve 10.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the inner bottom wall of the positioning plate 6 has a receiving opening 9, and the electromagnet 12 is lifted and lowered at the receiving opening 9 of the positioning plate 6.

[0022] Further as Figure 3 As shown, it is worth noting that the inner bottom wall of the positioning plate 6 is provided with a lifting groove 7, which slides and matches the lifting sleeve 10.

[0023] This solution has the following working process: Before use, the welding head 2 is driven by the lifting mechanism of the welding device 1 to descend and perform welding operations on the nut at the projection welding station. During the process of the positioning plate 6 pressing the nut, the lifting sleeve 10, which has an electromagnet 12 fixed inside, is slidably connected to the positioning plate 6. At the same time, the elastic structure formed by the lifting sleeve 10 and the second buffer spring 14 on the positioning plate 6 can reduce hard contact during the process of the electromagnet 12 descending and contacting the nut. The way of reducing the impact force during the contact of the electromagnet 12 with the nut can reduce the risk of damage to the electromagnet 12 due to long-term impact. After the projection welding is completed, the positioning plate 6 is reset under the drive of the lifting mechanism of the welding device 1. During this process, the electromagnet 12 generates magnetic force after being energized, which will attract and pull away the nut.

[0024] As can be seen from the above working process, the elastic structure formed by the lifting sleeve 10 and the second buffer spring 14 on the positioning pressure plate 6 can reduce hard contact during the process of the electromagnet 12 descending and contacting the nut. The way of reducing the impact force during the contact of the electromagnet 12 with the nut can reduce the risk of damage to the electromagnet 12 due to long-term impact.

[0025] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the inner bottom wall of the positioning plate 6 is provided with a clearance opening 8, and the lifting slide 7, the clearance opening 8 and the receiving opening 9 are connected.

[0026] Further as Figure 4 As shown, it is worth noting that the side surface of the lifting sleeve 10 is provided with a lifting clearance groove 16, the lifting clearance groove 16 of the lifting sleeve 10 is aligned with the clearance opening 8 of the positioning pressure plate 6, an anti-detachment end edge 11 is fixed at the lower edge of the side surface of the lifting sleeve 10, and a groove for accommodating the anti-detachment end edge 11 is provided on the lower end surface of the positioning pressure plate 6, and the connecting bracket 13 is slidably adapted to the lifting clearance groove 16 of the lifting sleeve 10.

[0027] Further as Figure 1 As shown, it is worth noting that a fixed seat 3 is fixed on the surface of the lifting mechanism of the welding device 1, a buffer guide post 4 is fixed on the upper end of the positioning pressure plate 6, the buffer guide post 4 slides through the inside of the fixed seat 3, a first buffer spring 5 is fixed between the positioning pressure plate 6 and the fixed seat 3, one end of the second buffer spring 14 is fixed on the inner bottom wall of the positioning pressure plate 6, and the upper end of the second buffer spring 14 is fixed on the assembly knob 15.

[0028] In summary: the elastic structure formed by the lifting sleeve 10 and the second buffer spring 14 on the positioning pressure plate 6 can reduce hard contact during the process of the electromagnet 12 descending and contacting the nut. The way to reduce the impact force during the contact of the electromagnet 12 with the nut can reduce the risk of damage to the electromagnet 12 due to long-term impact. During use, the elastic force of the second buffer spring 14 can be finely adjusted by turning the assembly knob 15 to adapt to the elastic force of the electromagnet 12.
