Problems solved by technology

In actual brazing, although measures such as controlling the amount of brazing material and applying flow-blocking agent are taken, it is still inevitable that the brazing material will accumulate, overflow, and splash. It is removed by conventional polishing knives and grinding heads, which is inefficient and difficult to guarantee. Design requirements

Abstract

The invention relates to a repairing and polishing device for redundant brazing filler metal of precision components, which adopts an electromechanical composite polishing and repairing head and an electromechanical composite polishing head; the anode of a power supply (1) is connected with an electric-conducting platform (20), cathode cables (24) of the power supply (1) are connected; a polishing solution transferring pipe (26) of a hollow pipeline (5) is communicated with the outlet of a liquid storage device (9), the electromechanical composite polishing head (6) is arranged on a clamping head of a minitype polishing and repairing gun (4); the polishing solution transmission pipe is communicated with a polishing and repairing gun protective sleeve and leads the polishing solution to be transferred to a processing part; cables of a double-layer hollow lead wire are communicated with a protective sleeve wiring column (13) on the polishing and repairing gun and realizes electrification of a clamping rod (11) by a carbon brush (14) in an inner hole of the wiring column on the protective sleeve. The device realizes electromechanical composite polishing and repairing, overcomes the disadvantages that the polishing and repairing amount in pure mechanical polishing and repairing is hard to control, and the polished surface is rough and is suitable for aftertreatment of the redundant brazing filler metal formed by overflowing guidance, splashing and spreading in the precision component soldering process in the aviation and spaceflight field.

Description

technical field [0001] The invention belongs to the field of welding auxiliary equipment, in particular to a repairing and polishing device for excess solder of precision parts. Background technique [0002] The national mid-to-long-term scientific and technological development plan lists large aircraft as a major national special project, and the large aircraft project puts forward strict requirements on engine safety, reliability, energy conservation and environmental protection, maintenance performance, and economy. In particular, the size, surface roughness, and surface integrity of blade parts in the development process of the fourth-generation aircraft engine have an important impact on the performance of the engine. In actual brazing, although measures such as controlling the amount of brazing material and applying flow-blocking agent are taken, it is still inevitable that the brazing material will accumulate, overflow, and splash. It is removed by conventional polish...
