Problems solved by technology

Although the existing circular saw blade laser welding device can realize welding, it has the following deficiencies. 1. Due to the use of single-sided laser irradiation, the required power of the laser welding machine is relatively high, and then there is a laser welding machine purchase cost Extremely high, which seriously limits the penetration rate of laser welding
2. Due to the single-sided laser irradiation, the saw blade substrate and the saw blade head are heated unevenly, and the finished circular saw blade has the risk of bending and deformation

Abstract

The invention provides a circular saw blade laser welding device, belongs to the technical field of welding, and solves the problem that an existing circular saw blade laser welding device is high inmanufacturing cost. The circular saw blade laser welding device comprises a rack and laser welding machine focusing heads, wherein a base body clamp for positioning a saw blade base body in the circular saw blade and a tool clamp for positioning a saw blade tool bit in the circular saw blade are mounted on the rack; the two groups of laser welding machine focusing heads are separately positioned at the two sides of the saw blade base body on the base body clamp; the two groups of laser welding machine focusing heads are connected with the rack through welding drive structures; and the two groups of laser welding machine focusing heads can weld one saw blade tool bit on the saw blade base body. The circular saw blade laser welding device adopts two laser welding machines to simultaneously weld joints between the saw blade tool bits of the laser welding machines and the saw blade base body, so that power of single laser welding machine can be reduced, and purchasing cost of the laser welding machines is reduced.

Description

technical field [0001] The invention belongs to the field of welding technology, and relates to a laser welding device, in particular to a circular saw blade laser welding device. Background technique [0002] Circular saw blade is a common cutting tool, the blade head is made of hard material, the saw blade base is made of ordinary steel, and the saw blade head is fixed on the saw blade base by brazing or laser welding. [0003] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Chinese patent literature has recorded about the use of laser welding circular saw blades, such as the focus head controller of diamond saw blade laser welding machine (authorized announcement number CN2333478Y), the oblique pressure plate clamp for laser welding diamond saw blade electromagnetic chuck (authorized announcement number CN100509251C). When conventional laser welding is used for circular saw blades, the base of the saw...
