Description

Laser welding tool Technical Field The utility model relates to the technical field of laser welding, in particular to a laser welding tool. Background The spare part in the current electric automobile automatically-controlled door product needs to carry out laser welding work, wherein this spare part has the ring type spare welding of round hole of having seted up to two lateral walls to constitute, this spare part circumference junction needs four welding seams of welding, need the tight control heat input of welding in-process guarantees welding quality, current spare part need cool off upset work after two welding seams of welding in the welding process, avoid the spare part to be heated the too high temperature, carry out the welding work of two other welding seams again, this just causes the cooling process to be in the welding work stagnated state, influence the whole efficiency of welding, therefore need design a duplex position, overturn the weldment in turn and can carry out the laser welding frock of prepositioning work to two ring type spare in order to solve above-mentioned problem. Disclosure of utility model The utility model aims to provide a laser welding tool for solving the problems in the background art. The technical scheme is that the laser welding tool comprises a base and a base arranged in the center of the base, wherein turnover air cylinders are arranged on two sides of the base, a rotating end of each turnover air cylinder is connected with a storage component, two ends of the base are fixedly provided with a propping component, a welding piece propped against the propping component is arranged in the storage component, the welding piece comprises two circular ring pieces with circular holes, a pre-positioning piece for positioning and assembling is arranged between the two circular ring pieces through the circular holes, and the laser welding components are arranged on two sides of the top of the base. The welding machine has the advantages that the welding piece formed by the two circular ring pieces can be pre-assembled and positioned through the pre-positioning piece, then the assembled welding piece is installed on the object placing assembly on the left side of the base, the welding piece is abutted tightly by the abutting assembly on the left side, then two welding seams at the top of the welding piece are welded by the laser welding assembly, the abutting assembly is loosened after the welding operation is finished, the overturning cylinder drives the welding piece to rotate for one hundred eighty degrees, the abutting assembly abuts the welding piece again, the welding operation of two welding seams at the other side of the welding piece is completed, the tool is divided into a left station and a right station, the overturning and positioning operation is carried out on the right station when the welding operation is carried out on the left station, the welding piece can be naturally cooled when the overturning and positioning operation is carried out on the left station, the welding operation is carried out on the two stations alternately and continuously by workers, the purpose of alternately welding operation is achieved, and the welding efficiency is effectively improved. Preferably, the object placing component comprises an object placing seat fixed on the rotating end of the overturning cylinder, and an object placing groove matched with the weldment is formed in the object placing seat. The welding part can be placed and fixed through the storage groove on the storage seat, and the welding part can be matched with the overturning cylinder to overturn. Preferably, the pre-positioning piece comprises a positioning piece, a positioning column inserted on the welding piece is fixed at the bottom of the positioning piece, and a hole is formed in the center of the top of the positioning piece. The positioning piece has the advantages that the positioning posts on the positioning piece can be inserted into the weldment, the two circular ring pieces are preassembled and positioned, and the holes of the positioning piece can facilitate laser welding. Preferably, an extension protrusion is arranged on one side of the positioning sheet, and a clamping groove matched with the extension protrusion is formed in the inner side of the storage groove. The part has the advantages that the extending protrusion can be clamped and matched with the clamping groove after the weldment is placed in the storage groove, so that the weldment is prevented from rotating. Preferably, the abutting assembly comprises a side frame fixed on the end side of the base, a pressing cylinder is fixed on the side frame, and an abutting plate for abutting the welding piece is fixed on the extending end of the pressing cylinder. The welding part has the advantages that the pressing cylinder can drive the pressing plate to press the welding part tightly, and shaking is avoided during welding. Compared with t
