Description
Technical Field
The present invention relates to a welding structure, and more particularly, to a welding electrode structure.
Background
For many electrically powered products, electrodes are provided, and some of the conductive posts or plates of the electrodes are typically soldered to other conductive posts or plates. However, in a factory, when two conductive columns or conductive plates are welded, not only high processing efficiency is required, but also a welded product is required to be firm and have low electrode loss.
There are many welding methods, but in view of cost, the prior art uses spot welding when the conductive column or conductive plate is welded with another conductive column or conductive plate. In addition, in the prior art, the electrode material is mostly made of tungsten copper, when the welded material of one electrode is made of nickel-plated zinc steel plate, and the welded material of the other electrode is made of copper plate, alloy is easily generated between copper in the electrode material and zinc in the welded material of one electrode when spot welding is carried out, so that the phenomenon of electrode adhesion is generated.
Once the welded material is adhered to the electrode, the consumption of the electrode on the adhered tungsten-copper electrode is large, and a gap is generated, thereby causing poor sparking.
On the other hand, the cross-sectional shape of the end of the existing electrode material is generally implemented as a circle. Therefore, the spot welding is easy to loosen after spot welding, and poor spot welding is easy to cause. More importantly, when the shape of the end of the electrode material is implemented as a circle, the end of the electrode material is easily rotated.
In addition, in the prior art, butt welding is mostly adopted for resistance welding, that is, a method of respectively placing weldments between two clamping devices, aligning end faces of the weldments, and heating and electrifying at a contact position for welding is adopted. However, for some products, the butt welding method is not suitable for the position where the electrode structure is arranged due to the interference of other fixing pieces.

A welding electrode structure according to a preferred embodiment of the present invention will be described in detail below with reference to fig. 1 to 4 of the drawings, wherein the welding electrode structure can be applied to window electrodes, servo electrodes, and other products requiring electrodes.
Specifically, the welding electrode structure includes an upper electrode conductor 10, an electrode connecting assembly 20, and a lower electrode conductor 30. The electrode connecting assembly 20 includes two welded members, specifically, a first welded member 21 and a second welded member 22.
At least one of the upper electrode conductor 10 and the lower electrode conductor 30 is implemented using an aluminum oxide copper material. One of the first welded member 21 and the second welded member 22 is implemented by nickel-plated zinc steel, and the other is implemented by copper.
The first welded member 21 or the second welded member 22, which is implemented as nickel-zinc plated steel, is welded to the upper electrode conductor 10 or the lower electrode conductor 30, which is implemented as an aluminum oxide copper material. The first welded member 21 or the second welded member 22 made of copper is welded to the first welded member 21 or the second welded member 22 made of nickel-zinc-plated steel, and the upper electrode conductor 10 or the lower electrode conductor 30. In this way, the upper electrode conductor 10 and the lower electrode conductor 30 are welded to each other by the electrode connecting assembly 20.
The first and second members to be welded 21 and 22 are welded and fixed at the same time as the upper electrode conductor 10 and the lower conductor 30 are welded, so that the first and second members to be welded 21 and 22 are bonded to each other.
Preferably, in the present invention, at least one of the upper electrode conductor 10 and the lower electrode conductor 30 is implemented using an aluminum oxide copper material.
In one example of the present invention, the upper electrode conductor 10 is implemented to be made of aluminum oxide copper. The lower electrode conductor 30 is implemented to be made of tungsten copper. Correspondingly, the upper electrode conductor 10 is welded as the first welded member 21, and the first welded member 21 is made of the nickel-zinc plated steel. At this time, the lower electrode conductor 30 is implemented by tungsten copper, and the second welded member 22 is implemented by copper.
In the present invention, the cross-sectional shape of the welded end of the upper electrode conductor 10 is implemented as a rectangle, and preferably, the cross-sectional shape of the end of the upper electrode conductor 10 is implemented as a rectangle of 2mm × 3 mm.
It is worth mentioning that if the cross-sectional shape of the welded end of the upper electrode conductor 10 is less than 2 × 3 (unit: mm), the electrode hardness is insufficient, the electrode wear is severe, and the production efficiency is low, and if the cross-sectional shape of the welded end of the upper electrode conductor 10 is greater than 2 × 3 (unit: mm), the heat is not easily concentrated during welding, and a good-quality welding spot is not easily obtained.
In the present embodiment, the top surface of the lower electrode conductor 30 forms a rectangle, preferably, the rectangle formed by the top surface of the lower electrode conductor 30 is implemented as a rectangle of 2mm × 3 mm.
It should be noted that, in the present embodiment, the upper electrode conductor 10 and the lower motor conductor 30 are not welded by the electrode connecting assembly 20 in a butt welding manner. But from two different perpendicular directions.
The vertically disposed end of the upper electrode conductor 10 is welded to the top surface 301 of the end of the lower electrode conductor 30 when disposed in the transverse direction by the electrode connecting assembly 20. It should be noted that the bottom electrode conductor 30 has a notch 301 formed on its top surface when it is laterally placed. The groove surface of the indentation 301 forms the top surface 301. The top surface 301 formed by the groove surface of the notch 301 is rectangular.
It is worth mentioning that the welding end of the upper electrode conductor 10 can be fixed by a locking screw, and the upper electrode conductor 10 and/or the lower electrode conductor 30 are not easily rotated relatively.
Since the upper electrode conductor 10 has a rectangular end section of 2 × 3 (mm), the upper electrode conductor 10 can be reused by further grinding to form a rectangular top surface of 2 × 3 (mm) after being deformed by wear, which facilitates recycling of the upper electrode conductor 10 to increase the life of the upper electrode conductor 10 in the case of a cone-shaped electrode in the prior art.
Further, preferably, the motor brush assembly includes the above welding electrode structure. Preferably, the first welded member 21 is implemented as one of the electrical terminals of the electrical breaker 80. The second welded member 21 is implemented as one electrical terminal of the brush arm 90. In one embodiment of the present invention, the end surface of the upper electrode conductor 10 and the end surface of the lower electrode conductor 30 are butt-welded by the welded assembly. The welded upper electrode conductor 10 and the welded lower electrode conductor 30 are in the same linear direction.
In the present embodiment, it is preferable that the sectional shape of the end of the upper motor conductor 10 is implemented as a rectangle of 2mm × 3mm and the sectional shape of the end of the lower motor conductor 30 is implemented as a rectangle of 2mm × 3 mm.
Experiments prove that when the welding electrode structure is adopted and tested, and the first welded part 21 and the second welded part 22 are directly pulled out by a drawing machine, the pulling-out force is larger than 50N, even larger than 100N, far exceeds the actual required value and the welding is firm under the condition of ensuring the product quality.
