Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. 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.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Example 1

The abdication extension type electrode cap of embodiment 1 shown in fig. 1 comprises a socket part 1 and an extension part 2. Wherein, an inner hole 12 is arranged in the sleeve joint part 1, the inner hole 12 is used for sleeve joint of the electrode connecting rod 4 (see fig. 5), and the extension part 2 is used for welding. The tail end of the extension part 2 is connected to the front end of the sleeve joint part 1, and the extension part 2 extends forwards from the front end of the sleeve joint part 1. As shown in fig. 2 and 3, the outer peripheral surface of the extension portion 2 is folded inward to leave an escape space 24. In this example, the cutting plane 22 is provided to be retracted. Due to the provision of the cutting plane 22, the extension 2 can be inserted into a small space. In this example, the outer peripheral surface of the extension 2 is provided with two cutting planes 22, and the two cutting planes 22 are parallel to each other, which facilitates the machining. In other embodiments, the manner of contracting the outer peripheral surface of extension portion 2 may be, for example, a manner of uniformly contracting the outer peripheral surface of extension portion 2, a manner of providing a cutting curved surface, or the like, and is not limited to the manner of providing cutting flat surface 22. The extension 2 is provided at its front end with a welding surface 21, the welding surface 21 being intended to be in contact with a steel plate 3 (see fig. 5) to be welded. The area of the welding surface 21 is smaller than the cross-sectional area of the extension portion 2, which is advantageous for energy concentration, and the tip of the extension portion 2 is smoothly received in the edge of the welding surface 21.

The extension portion 2 is worn and shortened during the welding operation, and if the extension portion 2 is too short, it cannot be used. In this example, as shown in fig. 1, the rear end of the extension 2 is provided with a warning groove 23, and the extension 2 cannot be used when it is consumed to the warning groove 23. The warning groove 23 facilitates visual judgment. The warning groove 23 has two front and back parts, when the extension part 2 is shortened to the front warning groove 23, a warning is given to a worker, and the replacement is needed as soon as possible; when the extension 2 is shortened to the latter warning groove 23, it is completely unusable.

The application scenario is illustrated in fig. 4 and 5, where fig. 5 is an enlarged view at a of fig. 4. Like figure 5, long and thin extension 2 can stretch into the narrow and small space that steel sheet 3 bending becomes, can weld the narrow and small position of product, has avoided the interference, makes welded product solder joint distribution accord with the requirement more, increases product intensity. The production efficiency and the quality of the automobile factory are improved.

Example 2

This example is substantially the same as embodiment 1 except that the shape of the extension 2 is different and the bore 12 extends into the extension 2. The shape of the extension 2 can be designed according to the shape of the product to be welded.

To sum up, the abdication extension type electrode cap of above-mentioned embodiment can weld various narrow and small spaces to convenient and welding system on the electrode arm installation, only need to change this abdication extension type electrode cap, greatly reduced the loss, practiced thrift the cost.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
