The utility model discloses have through processing an arc surface structure on current electrode body terminal surface, with the arc surface laminating of product, this physical stamina of electrode and the fine laminating of product circular arc contact surface during spot welding have been avoided because the product contact surface is the circular arc and take place the condemned condition of product that the offset of welding position leads to and appear, effectively improve product butt fusion quality for product stable quality, the great reduction of defective rate reduces the product and examines the smelting tool process entirely, has avoided the effect of customer because of the bad feedback of quality problem.

Description

Welding electrode

Technical Field

The utility model relates to a spot welding equipment technical field, more specifically say, it relates to a welding electrode.

Background

The spot welding is a practical connecting means in manufacturing means in the automobile industry, electrodes are arranged at upper and lower contact points of a direct current type resistance welding spot welder, and when the electric welder is electrified through the upper and lower electrodes, high temperature is generated instantly to weld two metals together. In the prior art, a product needs spot welding, but because the contact surface of the product is a circular arc, the welding position is often deviated during spot welding, so that the product is scrapped.

In view of the above problems, it is desirable to provide a welding electrode that can be attached to an arc surface of a product to ensure welding quality.

SUMMERY OF THE UTILITY MODEL

To this problem in the practical application, the utility model aims to provide a welding electrode, concrete scheme is as follows:

the utility model provides a welding electrode for as the contact of welding product, the welding contact surface of product is the arc surface, includes the electrode body, the one end terminal surface of electrode body establish into with the arcwall face structure that the product arc surface agrees with mutually.

Furthermore, the arc-shaped surface structure on the electrode body comprises two parallel surface structures and an arc-shaped surface structure, and one arc-shaped surface structure is positioned at the central position of the end surface of the electrode body;

the two parallel surface structures are respectively positioned on two sides of one arc surface structure, and the two parallel surface structures are symmetrical about the central line of the arc surface structure;

the two parallel surface structures are parallel to the cross section of the electrode body, and one arc surface structure is sunken towards the center direction of the electrode body.

Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model discloses in, processing an arc surface structure on current electrode body terminal surface, with the arc surface laminating of product, this physical stamina of electrode and the fine laminating of product circular arc contact surface during spot welding have been avoided because the product contact surface is the circular arc and take place the condemned condition of product that the offset of welding position leads to and appear, effectively improve product butt fusion quality for product stable quality, the great reduction of defective rate reduces the product and examines the smelting tool process entirely.

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1-4, a welding electrode is used as a contact element for welding a product 1, a welding contact surface of the product 1 is an arc surface, and includes an electrode body 2, preferably, the electrode body 2 is set to be a cylindrical structure, an end surface of the electrode body 2 is set to be an arc surface structure 3 matched with the arc surface of the product 1, and the arc surface structure 3 on the electrode body 2 is a contact surface with the product 1 during spot welding. Like this, during spot welding, the arc surface of product 1 contacts and laminates each other with arc face structure 3 on the 2 terminal surfaces of electrode body, carries out the spot welding to the condition of skew appears in the spot welding, guarantees spot welding quality.

In addition, in the utility model, the arc surface structure 3 on the electrode body 2 comprises two parallel surface structures 32 and one arc surface structure 31, the two parallel surface structures 32 are parallel to the cross section of the electrode body 2, and one arc surface structure 31 is sunken towards the center direction of the electrode body 2; arc surface structure

31 is located at the center position of the end face of the electrode body 2; the two parallel surface structures 32 are respectively located at two sides of one arc surface structure 31, and the two parallel surface structures 32 are symmetrical about the central line of the arc surface structure 31.

Adopt two parallel surface structures 32 and arc surface structure 31 matched with mode, when electrode body 2 contacted with product 1, not only had the arc spare on the product 1 and laminated mutually with arc surface structure 31 on the 2 terminal surfaces of electrode body, two parallel surface structures 32 were laminated each other with the arc surface both sides plane of product 1 equally on the electrode body 2 simultaneously, had improved the two laminating degree, had guaranteed the stability after the two contacted, had further improved the quality of spot welding.

The utility model discloses a concrete implementation principle does: the utility model discloses in, process an arc surface structure 31 on 2 terminal surfaces of current electrode body, with the arc surface laminating of product 1, product 1 can not take place the skew when receiving electrode pressure, effectively improves 1 butt fusion quality of product for 1 stable quality of product, the great reduction of defective rate reduces 1 full-detection tool processes of product, and more importantly has avoided the customer because of the bad feedback of quality problem.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
