Concentric welding method and device

Abstract

The invention discloses a concentric welding device which comprises a multi-axis linkage device, a three-plate type clamping jaw and a detecting device. The detecting device is fixed on the multi-axis linkage device and is connected with the multi-axis linkage device; the multi-axis linkage device comprises a servo motor, a storage and a processor, and the processor is respectively connected with the servo motor and the storage; the three-plate type clamping jaw is connected to a base and the servo motor on the multi-axis linkage device through a link rod; and the detecting device comprises a laser direct light source and a projection receiver which are mutually matched with each other. The invention also discloses a concentric welding method. Through the structure design for the three-plate type clamping jaw and the intelligent control on the multi-axis linkage device, the quality requirements on the coaxiality, the roundness, the intensity and the like of the welding product are ensured, the resources are fully utilized, the cost of the product is reduced and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a concentric welding method and device. Background technique [0002] According to market research, since the 1990s, the demand for PCB drills and milling cutters has been growing at a rate of 10-15% every year. With the development of high-tech electronic information technology and the improvement of people's living standards, the demand for PCB drills and milling cutters will increase. In 2011, the annual demand for micro drills and milling cutters in my country reached 3 billion and 4 billion respectively. 100 million sticks. [0003] The micro-drills and milling cutters used in the production of PCB (integrated circuit) boards all need to be imported, which is expensive. The price of imported tungsten carbide rods has been rising, while the price of finished products has been falling; the milling cutters used by manufacturers Knives and drills cannot be recycled or need to be re-melte...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a concentric welding method and device, which solves the problem that the strength of the tungsten steel bar after welding is not up to standard due to the concentricity, diameter and verticality of the welding end surface of the semi-finished product in the traditional butt welding process. The problem of not meeting the quality requirements can further solve the technical problems of oxidation blackening, solder hardening and residue caused by high temperature welding
