High-frequency brazing coil clamp

Abstract

The invention relates to a high-frequency brazing coil clamp. The high-frequency brazing coil clamp comprises an installation bottom plate, a first welding rod and a second welding rod. The installation bottom plate is provided with four sliding plates, a first air cylinder and a second air cylinder. The first sliding plate is opposite to the third sliding plate. The second sliding plate is opposite to the fourth sliding plate. The front end and the rear end of the first welding rod are arranged on the first sliding plate and the second sliding plate correspondingly. The front end and the rear end of the second welding rod are arranged on the third sliding plate and the fourth sliding plate correspondingly. Linkage is achieved between every two opposite sliding plates through a linkage mechanism. During working, the first air cylinder and the second air cylinder drive the four sliding plates to slide synchronously oppositely or slide reversely, and the effect that displacements of every two opposite sliding plates are the same during every time of folding can be ensured. Through the high-frequency brazing coil clamp, the effect that the centers of a high-frequency brazing coil of every time of folding are the same, the center is repeated and does not shift, and the high-frequency brazing coil can complete every time of welding work with high quality.

Description

technical field [0001] The invention relates to the technical field of high-frequency brazing fixtures, in particular to a high-frequency brazing coil fixture. Background technique [0002] The high-frequency brazing machine is an induction heating device that heats the solder to a certain temperature through an induction current to melt the solder, thereby connecting two metals of the same material or different materials. In recent years, with the rapid development of my country's economy and the overall development of China's home appliance industry, white goods have become the fastest growing variety in the home appliance industry. The manufacturing industry of white goods is gradually developing in the direction of intelligent technology. In the manufacturing process of white goods, the pipeline welding mainly uses high-frequency brazing technology and high-frequency brazing machine to weld. The existing high-frequency brazing machine needs coil fixtures to install high...

Problems solved by technology

In the manufacturing process of white goods, the pipeline welding mainly uses high-frequency brazing technology and high-frequency brazing machine to weld. The existing high-frequency brazing machine needs coil fixtures to install high-frequency brazing coils. High-frequency brazing The installation accuracy of the coil will directly affect the welding effect and heat dissipation, but the coil fixture of the existing high-frequency brazing machine has the following shortcomings: (1) During the working process, the two cylinders on the coil fixture drive the high-frequency coil respectively The two welding frames of the high-frequency coil move toward each other or move opposite to each other. Since they are driven by two independent cylinders, when the two welding frames of the high-frequency coil are closed, the two welding frames of the high-frequency coil are not linked, and the moving distance of the two welding frames may be different. The center of the high-frequency coil is easy to shift, and the two welding frames of the high-frequency coil are not limited in travel. Even if the thrust of the two cylinders is the same, when the two welding frames touch, it is easy to cause the center of the high-frequency coil to shift, eventually causing The copper pipe is welded through or the solder cannot be completely melted, resulting in incomplete welding, causing the compressor to wait for the welded workpiece to be scrapped or re-welded
