Description

Angle steel welding robot Technical Field The utility model relates to welding equipment, in particular to an angle steel welding robot. Background The angle steel welding robot is widely applied to the fields of steel structure manufacturing, power transmission tower assembly, mechanical equipment frame construction and the like. In a typical application scene, after an operator places an angle steel workpiece to be welded on a horizontal working platform, a welding robot recognizes the position of a welding line through a vision system, and controls a six-axis mechanical arm to carry a welding gun along a preset path to carry out welding operation. The existing system is generally provided with a pneumatic clamping device for fixing two ends of angle steel, and the welding track is corrected in real time by matching with a laser tracking sensor, so that the welding process can realize the self-adaptive adjustment of the angle of a welding gun and current and voltage parameters. And part of advanced equipment is integrated with an automatic feeding and discharging mechanism to form a semi-continuous production line from workpiece conveying to welding forming, so that the batch production efficiency of the angle steel members is remarkably improved. However, the existing technology still has obvious defects in practical application, and the core defect of the existing technology is that an effective dynamic positioning mechanism is lacking in a working platform. When long angle steel is welded, the conventional pneumatic clamp only performs punctiform fixation on two ends of a workpiece, and the middle section area is easy to generate elastic deformation under the action of welding thermal deformation and mechanical vibration, so that a welding seam track deviates from a preset path. In particular, when multi-layer multi-channel welding is performed, accumulated deformation caused by repeated heat input can lead the angle steel to displace in millimeter level, and the penetration uniformity and the appearance forming quality of butt welding seams are directly affected. In addition, the traditional positioning device lacks the quick adjustment function to different specification angle steel, and the reference surface needs to be manually and repeatedly calibrated when the workpiece is replaced, so that the equipment utilization rate is reduced, and the operation potential safety hazard is increased. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the angle steel welding robot with more stable positioning of the angle steel. In order to achieve the purpose, the angle steel welding robot comprises a robot for welding angle steel and a platform for placing the angle steel, wherein a positioning device for positioning the angle steel is arranged on the platform, the positioning device comprises a first positioning mechanism and a second positioning mechanism which are respectively used for positioning one angle steel, and the first positioning mechanism and the second positioning mechanism enable the two angle steels to form a vertical included angle after being positioned. The double angle steel welding device has the beneficial effects that by arranging two independent positioning mechanisms to form a synergistic effect of vertical included angles, accurate positioning and welding angle control of the double angle steel can be realized. The first positioning mechanism provides an axial positioning reference through the positioning block group which moves synchronously, the second positioning mechanism provides vertical constraint through the adjustable limiting component, and the welding included angle has a stable geometric relationship in a three-dimensional space through the cooperation of the first positioning mechanism and the second positioning mechanism. The first positioning mechanism can adopt a linkage sliding table structure with a guide groove, the two positioning blocks realize synchronous symmetrical movement through gear-rack transmission, the center lines of the two positioning blocks are ensured to be always coincident, the second positioning mechanism can adopt a sliding rail assembly with a rotary adjusting disc, the offset angle of the limiting block is precisely controlled through a dial, and the quick setting of the vertical included angle is realized by matching with a locking pin. The structural combination can prevent the processing deviation and adapt to the welding requirements of angle steel with different specifications. Further, the first positioning mechanism comprises two first positioning blocks which are respectively arranged on the platform in a sliding manner, first limiting holes for the insertion of angle steel are formed in the two first positioning blocks, and the two first positioning blocks are connected through a guide rail so that the central lines of the two first positioning blocks are always coincident.
