Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with aspects of the utility model as detailed in the accompanying claims.
An embodiment of the present utility model provides an electrode cap 10. Fig. 1 shows a schematic structure of the electrode cap 10. Fig. 2 shows a top view of the electrode cap 10. Fig. 3 shows a sectional view along the sectional line AA in fig. 2. As shown in fig. 1, 2 and 3, the electrode cap 10 includes: a welded portion 11 and a mounting portion 12.
The welded portion 11 is located above the mounting portion 12. The weld 11 includes a welding surface 111. The mounting portion 12 includes a mounting groove 121 and a notch 122. The welding surface 111 and the notch 122 are located at opposite end surfaces of the electrode cap 10.
Specifically, fig. 3 shows a first direction Z. The welded portion 11 is located on the upper surface of the mounting portion 12, that is, the welded portion 11 is located on the upper surface of the mounting portion 12 in the first direction Z.
Fig. 3 also shows the first end face M1 and the second end face M2 of the electrode cap 10. The first end face M1 and the second end face M2 are located at opposite ends of the electrode cap 10, i.e., opposite end faces of the electrode cap 10 may refer to the first end face M1 and the second end face M2. The welding surface 111 is the first end surface M1, and the notch 122 is located on the second end surface M2.
The mounting groove 121 extends from the notch 122 as a starting point in a direction toward the welded portion 11. I.e. the mounting groove 121 extends in the first direction Z starting from the notch 122.
The welding surface 111 is an arc surface, which protrudes in a direction away from the mounting groove 121. I.e. the welding surface 111 is a cambered surface protruding in the first direction Z.
Since the welding surface 111 of the welding part 11 needs to be in contact with the steel structure to be welded during welding. And, the welding surface 111 needs to be abutted against the structure to be welded under the action of pressure during welding. Also, due to the stress in the material, there is a tendency for the surface of the structure to be welded to tilt in the direction toward the electrode cap 10, in the direction outward from the center point D1 where the welding surface 111 contacts the structure to be welded. That is, as in the second direction X described in fig. 3, in a direction extending in the second direction X from the center point D1 of the welding surface 111 in contact with the structure to be welded, there is a tendency that the surface of the structure to be welded is tilted toward the electrode cap 10.
Although it is emphasized here that the electrode cap 10 is mainly used for welding steel structures, the electrode cap 10 is not limited thereto, and may be used for welding other material structures conforming to the welding standard.
As can be seen from the above embodiment, the welding surface 111 is set to be a cambered surface protruding along the first direction Z, so that the portion of the surface of the structure to be welded, which tends to tilt towards the electrode cap 10 during the welding process, can be effectively prevented from being extruded with the edge of the electrode cap 10, and thus, the trace on the surface of the structure to be welded during the welding process can be prevented, and further, the flatness of the appearance surface of the vehicle can be improved, so as to improve the overall appearance perceived quality of the vehicle.
In some embodiments, as shown in fig. 1 and 3, the welding surface 111 includes an arc having an arc radius of 200 mm or more and 400 mm or less. Preferably, the welding surface 111 may be a cambered surface having a cambered radius of 400 mm.
When the cambered surface is the cambered surface with the cambered surface radius in the range, the part with the tilting trend towards the direction of the electrode cap 10 on the surface of the steel structure can be prevented from being extruded with the edge of the electrode cap 10, and the phenomenon that the radian of the welding surface 111 is too large to enable the whole welding surface 111 to be well attached to the steel structure can be avoided, so that the phenomenon that marks are left on the surface of the steel structure in the welding process can be further avoided, and further, the flatness of the appearance surface of a vehicle can be further improved, and the overall appearance perception quality of the vehicle can be further improved.
In some embodiments, as shown in fig. 1, 2 and 3, the cross section of the welded portion 11 in the horizontal direction includes a circular cross section having a diameter of 20 mm or more and 25 mm or less. The second direction X is also shown in fig. 2. That is, referring to the second direction X shown in fig. 2 and 3, the cross section of the welded portion 11 in the second direction X includes a circular cross section having a diameter of 20 mm or more and 25 mm or less. That is, the first diameter Φ1 shown in fig. 2 and 3 is 20 mm or more and 25 mm or less.
When the cross section of the welding portion 11 in the horizontal direction is a circular cross section within the diameter range, the situation that the welding surface 111 is well attached to the surface of the steel structure due to too large or too small diameter of the welding portion 11 can be avoided, and adverse effects are caused on the surface of the steel structure can be further avoided, so that marks are left on the surface of the steel structure in the welding process, and further flatness of the appearance surface of a vehicle can be further improved, and overall appearance perception quality of the vehicle can be further improved.
In some embodiments, as shown in fig. 3, the mounting groove 121 includes a groove bottom 123. The groove bottom 123 is a bottom surface of the mounting groove 121 facing the welded portion 11. The diameter of the groove bottom 123 is smaller than the diameter of the notch 122.
By means of the arrangement, the electrode cap 10 can be conveniently installed through the installation groove 121, and meanwhile the groove bottom 123 with the relatively smaller diameter can be better abutted against a part for installing the electrode cap 10, so that the stability of the electrode cap 10 in the use process can be improved, and the influence on the welding process is avoided.
In some embodiments, as shown in fig. 3, the angle of both sides of the cross section of the mounting groove 121 in the vertical direction is 5.9 degrees or more and 6.1 degrees or less. In a preferred embodiment, the angle is 5.9 degrees or greater and 6.1 degrees or less. That is, the angle of both sides of the cross section of the mounting groove 121 in the first direction Z is 5.9 degrees or more and 6.1 degrees or less. More preferably, the angle is 5.96 degrees. That is, the angle of both sides of the cross section of the mounting groove 121 in the first direction Z is 5.96 degrees. Referring to the first angle A1 shown in fig. 3, the angles of both sides of the cross section of the receiving groove 121 in the vertical direction are 5.96 degrees, that is, the first angle A1 is 5.96 degrees.
When the first angle A1 is 5.96 degrees, the groove bottom 123 with a relatively smaller diameter can be better abutted against the part for mounting the electrode cap 10, and the mounting groove 121 can be matched with the part for mounting the electrode cap 10 more firmly, so that the stability of the electrode cap 10 in the use process can be further improved, and the influence on the welding process is avoided.
In some embodiments, as shown in fig. 1, 2 and 3, a repair line 13 is further provided between the welding portion 11 and the mounting portion 12. The repair line 13 is a groove extending along the junction of the welding portion 11 and the mounting portion 12 and surrounding the electrode cap 10.
Specifically, as shown in fig. 3, the repair line 13 may be a groove having a triangular cross section. By setting the cross section of the repair line 13 to be triangular, the structure of the repair line 13 can be kept simple and stable, but the repair line 13 is not limited to this, and the cross section can be other shapes which can enable the groove structure to be simple and stable.
By providing the repair line 13, the welded portion 11 and the mounting portion 12 can be distinguished significantly. Since the welded portion 11 is worn during welding, the linear distance between the welding surface 111 and the repair line 13 is gradually shortened. After the repair line 13 is disposed, when the linear distance between the welding surface 111 and the repair line 13 is shorter than the expected length, or the edge of the welding surface 111 coincides with the repair line 13, the electrode cap 10 can be reminded of being scrapped, so that the fit relationship between the mounting portion 12 and the structure for mounting the electrode cap 10 can be prevented from being influenced in the continuous abrasion process of the electrode cap 10, the problems of displacement or falling off of the electrode cap 10 in the welding process can be avoided, and the stability of the electrode cap 10 in the use process can be further improved, and the influence on the welding process can be avoided.
In some embodiments, as shown in fig. 3, the distance from the repair line 13 in the vertical direction of the welded portion 11 is 5 mm or more and 10 mm or less. That is, the distance between the apex of the welding surface 111 of the welding portion 11 in the first direction Z and the repair line 13 is 5 mm or more and 10 mm or less. Referring to the first distance H1 shown in fig. 3, the distance from the repair line 13 of the welded portion 11 in the vertical direction is 5 mm or more and 10 mm or less, that is, the first distance H1 is 5 mm or more and 10 mm or less.
When the distance between the welding portion 11 and the repair line 13 in the first direction Z is within the above range, the stability of the installation of the electrode cap 10 and the economical efficiency of using the electrode cap 10 can be both considered, and thus, the cost of using the electrode cap 10 can be reduced while ensuring the performance of the electrode cap 10.
Fig. 4 shows a schematic view of the structure of a spot welding holder 20. As in the embodiment shown in fig. 4, the embodiment of the present utility model also provides a spot welding tongs 20, the spot welding tongs 20 including any of the electrode caps 10 described above.

Although it is emphasized here that the welding jig 20 is mainly used for welding steel structures, the welding jig 20 is not limited thereto, and may be used for welding other material structures conforming to the welding standard.
In some embodiments, FIG. 5 illustrates a schematic view of a spot welding tongs 20 performing a weld. As shown in fig. 4 and 5, the spot welding tongs 20 includes a first electrode rod 211 and a second electrode rod 212 which are disposed correspondingly.

An electrode cap 10 is provided on the welding end 213 of the first electrode rod 211, and an unmodified electrode cap 30 is provided on the welding end 213 of the second electrode rod 212. And the spherical portion of the part 32 to be welded between the electrode cap 10 and the unmodified electrode cap 30 is the welding spot 31.
By disposing the electrode cap 10 only on the welding end 213 of the first electrode rod 211, it is possible to use the unmodified electrode cap 30 at a place where the human eye perception is not high to reduce the cost while ensuring that the outer side of the member to be welded 32 is not left with a weld mark to affect the appearance, and thus, it is possible to make the spot welding tongs 20 compatible with avoiding leaving a weld mark to affect the appearance and reducing the overall welding cost.
