Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.
In the prior art, a first component and a second component need to be welded together, as shown in fig. 1-5, a first component 10 'has a sleeving hole 110', a second component 20 'has a welding column 210', and the welding column 210 'has a hole 211', when welding, firstly, the sleeving hole 110 'of the first component 10' is aligned with the welding column 210 'of the second component 20' to further sleeve the first component 10 'on the welding column 210', and at this time, the top of the welding column 210 'extends out of the sleeving hole 110'; then, the welding column 210 ' extending out of the sheathing hole site 110 ' is heated, so that the part of the welding column 210 ' is in a molten state; finally, the welding head 30 ' presses down the welding column 210 ' of the melted portion to flatten the portion extending out of the sheathing hole site 110 ' of the first member 10 ' and to make the cross-sectional size of the portion larger than that of the sheathing hole site 110 ' after the flattening, thereby welding the first member 10 ' and the second member 20 ' together. However, in this process, since the weld column 210 'in a molten state is like a lubricant, the welding head 30' is prone to shift during the pressing process, which causes the actual welding position to shift from the center of the weld column 210 ', especially when the surface of the first component 10' facing the welding head 30 'forms an angle with the horizontal plane, as shown in fig. 5, which is more prone to cause the actual welding position to shift from the center of the weld column 210'.
It will be appreciated that the first part 10 'may be a vehicle door having a hole for receiving a cover, and the second part 20' may be a handle having a weld stud at an end facing the vehicle door, the handle being secured to the interior of the vehicle door by welding, although the first part 10 'and the second part 20' may be two parts to be connected to other devices.
In the case of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In order to solve the above technical problem, an embodiment of the present invention provides a welding head 30, as shown in fig. 6 to 9, the welding head 30 may include: the welding head comprises a welding head body 310 and a positioning column 320, wherein the welding head body 310 is provided with a first end surface 311 and a second end surface 312 which are opposite, the positioning column 320 extends from the first end surface 311 to a direction far away from the first end surface 311, and the extending direction of the positioning column 320 is the same as the direction from the second end surface 312 to the first end surface 311; the positioning post 320 is used to insert into the hole 211 of the solder post 210.
Specifically, the welding head 30 may be connected to a robot arm to lower the welding head 30 and press the welding column 210, or may be connected to a cylinder to lower the welding head 30 and press the welding column 210, and of course, the welding head 30 may also be connected to other devices to lower the welding head 30 and press the welding column 210, which is not limited in this respect by the embodiment of the present invention; the welding head body 310 and the positioning column 320 can be integrally formed, so that the manufacturing processes are reduced, and the manufacturing cost is reduced.
When in use, referring to fig. 9, first, the sleeving hole 110 of the first component 10 is aligned with the welding column 210 of the second component 20, and then the first component 10 is sleeved on the welding column 210, at this time, the top of the welding column 210 extends out from the sleeving hole 110; then, the welding column 210 extending out of the sleeving hole site 110 is heated, so that the part of the welding column 210 is in a molten state; finally, the bonding head 30 is lowered, and during the lowering process, the positioning post 320 of the bonding head 30 is inserted into the hole 211 of the bonding post 210, and during the further lowering process of the bonding head 30, the bonding head 30 presses down the bonding post 210 of the melted portion, thereby bonding the first component 10 and the second component 20 together.
In this embodiment, before the actual welding of the welding head, the positioning column of the welding head is inserted into the hole of the welding column, so as to achieve the relative positioning between the welding head and the weldment, prevent the sliding of the welding head, and improve the welding quality, where the weldment is the second component described above.

Specifically, the molding cavity 330 is an annular recess on the first end surface 311, before the actual welding, the molding cavity 330 covers the welding column 210 in the molten state, and then the welding head 30 is pressed down to make the welding point formed by the welding head 30 mushroom-shaped, that is, the welding column 210 extending out of the sleeving hole 110 of the first component 10 is heated and pressed down to form a mushroom-shaped welding point.
Further, the annular bottom wall of the molding cavity 330 is horizontal; alternatively, the annular bottom wall of the molding cavity 330 is sloped.
Specifically, the annular bottom wall of the molding cavity 330 is horizontal, which is suitable for the surface of the first component 10 facing the bonding head 30 to be horizontal; the annular bottom wall of the molding cavity 330 is inclined as described above, which is suitable for the case that the surface of the first component 10 facing the welding head 30 is also inclined, in other words, the annular bottom wall of the molding cavity 330 and the surface of the first component 10 facing the welding head 30 are parallel to each other, so that the mushroom-shaped top is parallel to the surface of the first component 10 facing the welding head 30, and thus, the visual effect after welding is better.
In an embodiment of the present invention, the outer diameter of the positioning column 320 is smaller than the inner diameter of the hole 211 of the welding column 210 by 0.4-0.6mm, so that the hole 211 inserted into the welding column 210 through the positioning column 320 prevents the welding head 30 from sliding, thereby improving the welding quality and making the positioning process of the positioning column 320 smoother.
In one embodiment, the outer diameter of the positioning post 320 is 0.5mm smaller than the inner diameter of the hole site 211 of the solder post 210.
