Description

Auxiliary target and backboard brazing positioning and centering device

Technical Field

The utility model relates to the technical field of material welding, in particular to a positioning and centering device for brazing an auxiliary target and a backboard.

Background

In modern manufacturing industry, brazing technology is widely applied to the fields of electronics, aerospace, medical appliances and the like, and particularly in the welding process of a target material and a backboard, accurate centering and positioning are key links for ensuring welding quality. The welding quality of the target material and the backboard directly influences the performance and the service life of the product, so that extremely high requirements on welding accuracy are provided. However, the conventional centering and positioning method of the target and the back plate has a plurality of limitations, and is difficult to meet the requirements of modern high-precision manufacturing.

Firstly, the traditional centering and positioning method mainly relies on manual operation, and an operator realizes the centering of the target and the backboard through naked eye observation and manual adjustment. This method is not only inefficient, but also susceptible to human factors such as experience of operators, visual errors, and operational fatigue, etc., resulting in difficulty in ensuring centering accuracy. Particularly in mass production, the repeatability and consistency of manual operation are poor, so that unstable welding quality is easily caused, and the qualification rate of products is affected. Second, conventional centering devices often lack flexibility to accommodate targets of different sizes and shapes. In actual production, the size and shape of the target may vary depending on the product requirements, and conventional devices often require replacement or adjustment of the jig, which not only increases the production preparation time, but may also cause a decrease in centering accuracy. In addition, the fixture of traditional device adopts fixed design generally, can't realize finely tuning, leads to the target and the centering error of backplate great, is difficult to satisfy high accuracy welded requirement. In addition, the stability and the degree of automation of the traditional centering device are low. In the welding process, the target material and the backboard need to keep a stable contact state so as to avoid the generation of welding defects. However, the conventional apparatus is easily affected by external vibration or the structure of the apparatus itself during the clamping and positioning processes, resulting in a shift in the positions of the target and the back plate, thereby affecting the welding quality. Meanwhile, the conventional device generally lacks an automatic function, and an operator needs to manually complete a plurality of steps such as centering, clamping and welding, which not only increases labor intensity, but also reduces production efficiency.

In summary, the traditional centering and positioning method for the target and the backboard has obvious defects in the aspects of precision, flexibility, stability, automation degree and the like, and is difficult to meet the requirements of modern high-precision manufacturing.
