Problems solved by technology

[0002] Exhaust manifold is an important part in automobile manufacturing. At present, manual welding is mainly used in the welding process of exhaust manifold. However, the existing manual welding cannot complete the welding of the weld seam at one time, and the weld seam is uniform during welding. poor performance, resulting in unstable welding quality; at the same time, it is necessary to repeatedly fix the exhaust manifold in the fixture to adjust the butt weld during welding, which seriously affects production efficiency and increases labor costs; and the inner surface of the exhaust manifold after welding is completed There are welding slag, burrs and other debris in the weld, which will increase the exhaust resistance, and the exhaust will be disordered, which will affect the normal operation of the engine; the air tightness of the weld cannot be detected in time after welding. If the air tightness is poor, it needs to be reworked ,Time-consuming

Embodiment 1

[0031] 1. An exhaust manifold automatic welding equipment, comprising an equipment frame 1, a single-section welding workbench 2, a welding handling detection manipulator 3, a flange slideway 4, a combined welding workbench 5 and a polishing device 6; the equipment The frame 1 is provided with four groups, and each group is fixedly connected by two upper and lower horizontal sliding rods 1.1. The single-section welding table 2 is provided with two groups, and the bottom of the single-section welding table 2 is provided with a linear motor I2 .1, the linear motor I2.1 is socketed on the slide bar 1.1, the top of the linear motor I2.1 is fixed with four support rods I2.2, and the top of the support rod I2.2 is fixed on two sets of brackets 2.3, the middle part of the bracket 2.3 is provided with a rotating shaft 2.4, the rotating shaft 2.4 passes through the bracket 2.3, the end of the rotating shaft 2.4 is connected with a turning servo motor 2.5, and the rotating shaft 2.4 is s...

Embodiment 2

[0038] The structure and principle of this embodiment 2 are basically the same as that of embodiment 1, the difference is that the middle and lower part of the flange slideway 4 is provided with a stop cylinder 4.2, and the stop cylinder 4.2 can adjust the sliding pressure of the flange to avoid a large number of flanges If the sliding pressure is too large, the clamping cylinder II cannot be fully clamped, causing the flange to drop.

Embodiment 3

[0040] The structure and principle of this embodiment 3 are basically the same as that of embodiment 1, the difference is that the piston chamber I 6.11 and the piston chamber II 6.26 are equipped with a pressure detection device 6.27, and the pressure detection device 6.27 can detect the grinding and extrusion The pressure is fed back to the control system to control the polishing pressure inside the exhaust manifold to improve the polishing quality.

Abstract

The invention provides an exhaust manifold automatic welding device and a working method thereof. The exhaust manifold automatic welding device comprises an equipment frame, a single-segment welding workbench, a welding and carrying inspection mechanical arm, a flange slideway, a combined welding worktable and a polishing device; the single-segment welding workbench can move a butt weld left and right and overturn the butt weld, an arranged clamping jaw can rotate a welding piece during welding, a clamping and welding device of the welding and carrying inspection mechanical arm has the functions of welding, carrying and detecting, the flange slideway can automatically slide down a flange and a manifold head segment butt weld, the combined welding worktable can combine and joint all manifold segments together, and a polishing process can be automatically started after welding of an exhaust manifold. By means of the exhaust manifold automatic welding device and the working method, a segment welding working mode is adopted, the head segment flange and a curved segment pipe are respectively welded, and then overall welding of the butt weld is carried out in the combined worktable; andfluid abrasive particles are used for polishing the inner surface of the pipe, the mechanical arm conducts weld detection after welding is completed, and the exhaust manifold automatic welding deviceand the working method are very suitable for meeting the exhaust manifold welding process requirement.
