Problems solved by technology

This kind of equipment and method has good welding quality, but the equipment is huge and complicated, the cost is high, and the operation is inconvenient
With this equipment and method, since the double gantry frame is fixed, the station must be fixed, the operating space is small, the placement of the workpiece is troublesome, and the operation is inconvenient; with this equipment and method, it is necessary to add a set of steel plate conveying device and adjustment device, the cost is relatively high; with this equipment and method, the workers cannot adjust the parallelism between the movement track of the welding trolley and the weld seam intuitively and conveniently, and must detect the position of the weld seam by installing a high-precision weld seam tracking device. It is very expensive to install a two-axis linkage numerical control system to accurately adjust the position of the welding torch in real time, and the effect is not ideal due to the high heat, large electromagnetic interference and smoke in the submerged arc welding process.
[0004] At the same time, in the welding of the fixed gantry in the prior art, the positioning of the workpiece is relatively simple, so the accuracy is not high, and it is impossible to form an adjustable ideal state with the welding system of the fixed gantry, and the positional relationship and angle of the two cannot be accurately controlled relationship, so the welding effect is not ideal. At the same time, there are often quality differences in the welding of different workpieces, different positions, and angles, which causes quality problems for product splicing.

Embodiment Construction

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033]The invention provides a workpiece positioning auxiliary device for thin plate splicing submerged arc welding machine. The workpiece positioning auxiliary device is arranged under the half-gantry frame body and used in conjunction with the half-gantry frame body. The semi-gantry frame body It can move longitudinally, and there is a trolley on it, and the trolley can move horizontally. The difference between it and the prior art is that the auxiliary device for positioning the workpiece includes a bilatera...

Abstract

The invention relates to a workpiece positioning auxiliary device for a thin plate splicing submerged arc welding machine. The workpiece positioning auxiliary device comprises a bilateral pressure frame device, weld seam alignment and fine adjustment devices disposed at both ends of the bilateral pressure frame device and a grounding device disposed on a half gantry frame body. The bilateral pressure frame device comprises a main pressure frame and an auxiliary pressure frame which are arranged in parallel for simultaneously pressing two steel plates to be spliced, and the bilateral pressure frame device is provided with an adjusting beam and a welding trolley device. The weld seam alignment and fine adjustment devices are disposed at both ends of the adjusting beam for driving the adjusting beam to rotate clockwise or counterclockwise, so that a weld seam is parallel to a track of a welding trolley. The operation of the half gantry frame body is more precise by using auxiliary devices, the auxiliary devices are perfectly matched with the welding trolley and workpieces, and the precise control is achieved; and the welding work of the workpieces is realized at any position within the movement coverage area of a half gantry frame assembly, no position requirement is proposed for welding stations, and the logistics and transportation are convenient and the site utilization rate ishigh.

Description

technical field [0001] The invention relates to the technical field of thin plate splicing, in particular to a workpiece positioning auxiliary device for thin plate splicing submerged arc welding machines. Background technique [0002] In industrial production, two kinds of welding equipment and methods are mainly used for submerged arc welding of thin steel plates, and the method of submerged arc welding with fixed gantry and double-sided multi-head pressing is mostly used. [0003] The method of submerged arc welding of fixed gantry and double-sided multi-head pressing is to make a double gantry frame and fix it on the ground. A guide rail and a trolley are installed on one side of the double gantry gantry. The trolley is driven by a motor and can move laterally along the guide rail. The trolley is equipped with Submerged arc welding adjustment device, many hydraulic pressure heads with a distance of 300 mm to 500 mm are installed on the beams on both sides of the double g...
