Example 3
Taking zinc aluminum magnesium steel strips with the thickness of 2mm as raw materials as an example, taking zinc aluminum magnesium steel strips with the thickness of 4mm as raw materials as an example, the number of the clamping mechanisms 14 is six, one of the clamping mechanisms 14 is arranged in the vertical direction close to the top, the six clamping mechanisms 14 are distributed and arranged on the vertical support platform 2 in a ring shape by taking the circle center of the round hole of the vertical support platform 2 as the origin, the number of the second transmission chain wheel group 10, the tensioning chain wheel group 11 and the number of the gear groups 17 are six correspondingly, and the number of the first mounting holes 20, the second mounting holes 21 and the guide limiting blocks 22 is six.
During laser welding, the zinc-aluminum-magnesium electric pole is driven to slowly pass through the round hole through the feeder platform 1, meanwhile, the transmission chain group 12 is driven to move through the bidirectional double-acting oil cylinder 5, then the first transmission chain group 6 and the second transmission chain group 10 are driven to synchronously rotate, as the second transmission chain group 10 and the gear group 17 are coaxially arranged, the gear group 17 is driven to synchronously rotate through the rotating shaft by the second transmission chain group 10, the gear group 17 is meshed to drive the toothed plate 16 to move towards the circle center direction of the round hole near or far away from the center of the vertical supporting platform 2, the compression of the zinc-aluminum-magnesium electric pole is realized from six directions, when the number of the clamping mechanisms 14 is more, the stress on the periphery of the zinc-aluminum-magnesium conical tube is also more uniform, so that the deformation during processing is reduced, the width of a welding seam is narrower during laser welding is ensured, the influence on the surface anti-corrosion coating of a zinc-aluminum-magnesium steel belt is reduced, and after welding and painting is finished, the bidirectional double-acting oil cylinder 5 reversely acts to reset the toothed plate 16 and the clamping mechanism 14, so that the subsequent continuous laser welding processing is convenient.
For zinc-aluminum-magnesium steel strips with different thicknesses, the thinner the thickness is, the more the number of the clamping mechanisms 14 is correspondingly arranged during laser welding, so that the deformation during the machining is reduced, the smaller the width of a welding seam controlled during the welding is, and the influence on the corrosion resistance of the surface corrosion-resistant coating is reduced.
Similarly, the thickness of the ring which is fixedly connected with the middle position of the guide wheel 29 and protrudes outwards can be selected according to the actual situation, the thickness of the ring can be correspondingly set to be thin for a small point for the zinc-aluminum-magnesium electric pole with a thinner pipe wall, the thickness of the ring can be correspondingly set to be thick for the zinc-aluminum-magnesium electric pole with a thicker pipe wall, and particularly, for example, for an electric pole with 8 meters, the thickness of the selected raw material is thinner, the annular supporting piece with the thickness of 1.5mm is selected, so that the width of a welding line is smaller, the perforation during laser welding and the influence on an anticorrosive coating are reduced, for example, for an electric pole with the specification of 12 meters, the thickness of the raw material wall is selected for a zinc-aluminum-magnesium plate strip with the thickness of 3mm, and the corresponding annular supporting piece 23 is selected for improving the strength of a laser welding position.
The automatic welding equipment for the zinc-aluminum-magnesium electric pole and the using method thereof solve the problem that the welding seam is difficult to control when the zinc-aluminum-magnesium electric pole is welded, realize the automatic welding and the anti-corrosion spraying of the conical zinc-aluminum-magnesium electric pole by designing the automatic feeding laser welding fixture structure, and simultaneously ensure the uniformity of the welding seam width and high welding quality.
