Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are a part of the embodiments of the present invention, not all of the embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention.

Example 1: as shown in fig. 1:

The welding body 301 and the fixing body 302 are coaxial cylinders, the diameter of the welding body 301 is smaller than that of the fixing body 302, the welding surface 1 is connected with a support lug of an automobile shock absorber, and the fixing body 302 is connected with parts of an automobile chassis, such as a brake pipe and other line pipelines. The tool body 3 is made of aluminum oxide copper. The fixing surface 2 is provided with a round hole, the circle center of the round hole is arranged on the axis of the fixing body 302, the round hole extends along the axis to the direction of the welding body 301, a first through hole 201 is formed after the round hole extends, and the first through hole 201 is provided with threads used for being connected with parts of an automobile chassis.

Fig. 1 is a schematic cross-sectional view of an electrode assembly, and it can be seen from the drawing that a conical recess is formed in the deep part of a first through hole of the present invention, because the electrode assembly is manufactured by a pointed electric rotary head in the production process, the manufacturing is fast and convenient, and therefore, a recess is formed in the deep part of the first through hole, which does not affect the connection between the first through hole and the automobile parts. The diameter of the fixing body is larger than that of the welding body, and the first through hole is formed in the fixing body, so that the diameter of the fixing body is increased, and the whole electrode tool is more stable. The integral connection of the invention means that the welding body 301 and the fixing body 302 are two parts of the same tool body 3, so that in order to make the material of the welding surface 1 be alumina copper, the whole tool body 3 is made of alumina copper, which is convenient for industrial large-scale production and manufacture, and the performance of the alumina copper and the chromium zirconium copper are as shown in table 1:

name (R)	Chemical formula	Hardness of	Conductivity% IACS	Softening temperature of	Price
						Chromium zirconium copper	CrZrCu	>75HRB	≥75％	≥500	Lower than aluminum oxide copper
Aluminum oxide copper	Al2O3Cu	>80HRB	≥85％IACS	≥930	High purity chromium zirconium copper

Table 1: comparison table for various performances of chromium zirconium copper and aluminum oxide copper

It can be seen from the table that after the new electrode tool is made of aluminum oxide copper, the conductivity of the welding electrode is improved, the hardness of the aluminum oxide copper is higher than that of chromium zirconium copper, the softening temperature of the aluminum oxide copper is higher than that of the chromium zirconium copper, and the aluminum oxide copper is more stable than the chromium zirconium copper under the high-temperature welding condition of resistance welding.

Example 2: as shown in fig. 2, 3 and 4:

the invention provides an electrode tool containing aluminum oxide copper and suitable for an automobile shock absorber, which comprises a welding surface 1, a fixing surface 2 and a tool body 3, wherein the tool body 3 comprises a welding body 301 and a fixing body 302, one end of the welding body 301 is the welding surface 1, the other end of the welding body 301 is connected with the fixing body 302 in a same body, the other end of the fixing body 302 is the fixing surface 2, and the welding surface 1 is made of aluminum oxide copper. The welding body 301 includes welding base column 4 and welding cap 5, the one end of welding cap 5 is face of weld 1, the other end of welding cap 5 passes through the screw thread and is connected with welding base column 4, welding base column 4 and the same body coupling of fixed body 302. The welding cap 5 is made of aluminum oxide copper, and the welding base column 4 and the fixing body 302 which are connected with each other in a same body are made of red copper or chromium zirconium copper. The welding body 301 and the fixing body 302 are coaxial cylinders, the diameter of the welding body 301 is smaller than that of the fixing body 302, the welding cap 5 is connected with a support lug of an automobile shock absorber, and the fixing body 302 is connected with parts of an automobile chassis, such as a brake pipe and other line pipelines. The welding cap 5 comprises a head and a screw, the welding base column 4 is provided with a second through hole 401 matched with the screw, and the screw and the second through hole are fixedly connected through threads. The fixing surface 2 is provided with a round hole, the circle center of the round hole is arranged on the axis of the fixing body 302, the round hole extends along the axis to the direction of the welding body 301, a first through hole 201 is formed after the round hole extends, and the first through hole 201 is provided with threads used for being connected with parts of an automobile chassis. The first through hole 201 and the second through hole 401 are on the same axis. In this embodiment, the manufacturing processes of the first through hole and the second through hole are the same as those of the first through hole in embodiment 1, and are all manufactured through the electric rotary head, so that the whole part without the through hole can be manufactured conveniently and quickly, and the production efficiency is greatly improved.

The integral connection of the invention means that the welding base column 4 and the fixing body 302 are two parts of the same tool body 3, and then the welding cap 5 and the welding body 301 are connected through threads, which can facilitate the installation of part of automobile parts, so that the installation is simpler and more convenient, and the performance of the aluminum oxide copper and the chromium zirconium copper are shown in table 1 in example 1.

From the table we can see that the conductivity of copper aluminum oxide is greater than that of chromium zirconium copper, the hardness of copper aluminum oxide is also higher than that of chromium zirconium copper, the softening temperature is greater than that of chromium zirconium copper, and the copper aluminum oxide is more stable than chromium zirconium copper under the high-temperature welding conditions of resistance welding. However, the price of the aluminum oxide copper is higher than that of the chromium zirconium copper, so the embodiment only sets the manufacturing material of the welding cap 5 as the aluminum oxide copper, and the rest is the chromium zirconium copper, which can meet the requirement of industrial mass production and save the cost.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
