Description

Laser welding auxiliary device for machining automobile parts Technical Field The invention relates to the technical field of laser welding assistance, in particular to a laser welding assistance device for machining automobile parts. Background As a high-efficiency and precise connecting technology, the laser welding has the advantages of high energy density, small heat affected zone, high welding speed, easiness in automation and the like, and is widely applied to the field of automobile part processing, in particular to the manufacture of key parts such as a vehicle body structure, a power assembly, a battery tray and the like. However, in the process of welding automobile parts, in order to increase the welding quality and efficiency, an auxiliary device is required to be arranged on the welding equipment, so that the parts are assisted in aspects of feeding and discharging, positioning and clamping, smoke treatment generated in the welding process and the like. At present, a common laser welding workstation generally adopts a fixed tool to be matched with a laser welding manipulator for welding. The workpieces to be welded are usually carried to a welding station by a manual or simple conveying line, clamped by a fixing clamp and then welded, and then taken down by a manual or mechanism after the welding is completed. This approach suffers from the following disadvantages: The loading and unloading efficiency is low, and the production beat is influenced, namely, in the welding process, the laser welding manipulator is in a waiting state until the disassembly of the welded workpiece and the clamping of the workpiece to be welded are manually completed. This serial mode of operation results in poor equipment utilization, limiting productivity gains. The automation and flexibility degree is insufficient, the labor intensity is increased by manual feeding, discharging and positioning, and the consistency is difficult to ensure. For production modes of multiple varieties and small batches, the time for replacing the clamp and adjusting the station is long, and the flexibility of the system is poor. The problem of welding fume pollution is that the high temperature generated in the moment of laser welding can vaporize metal to generate a great amount of metal vapor and tiny particles so as to form welding fume. If the smoke dust cannot be effectively removed in time, the smoke dust can pollute the working environment, endanger the health of operators, and can be deposited on the surfaces of precision parts such as laser lenses, sensors and the like, so that the normal working life and the welding quality stability of the precision parts are affected. Existing equipment often needs to be additionally provided with an independent large-scale dust removal system, occupies a large area and has limited effect on capturing a smoke source. The positioning and clamping modes are to be optimized, and the traditional rigid clamp can cause clamping deformation or surface damage to complex or thin-wall parts, and the clamp can sometimes interfere with a laser path for a workpiece needing laser welding from the side. Therefore, there is a need to design a laser welding auxiliary device which has high integration level, can realize rapid and automatic feeding and discharging, has flexible clamping capability, and can effectively treat welding smoke dust, so as to improve the automation level, the production efficiency and the environmental friendliness of the automobile part laser welding production line.
