Description
Technical Field
[0001] The utility model relates to the field of automatic welding equipment, in particular to an automatic welding equipment for steel grating plates. Background Art
[0002] The steel grating plate is also called steel grid plate. The grid plate is a steel product made by arranging flat steel in a certain spacing and cross bars and welding them into a square grid in the middle. It is mainly used as a water channel cover plate, a steel structure platform plate, a tread plate of a steel ladder, etc. The cross bar is generally made of square steel after being twisted.
[0003] In the prior art, during the production of steel grating plates, it is often necessary to use a numerical control welding machine, an automatic welding equipment, to perform welding processing on the steel grating plates. When welding the edge of the steel grating plate, the steel grating plate needs to be placed on the welding table, and the steel grating plate is fixed by a fixing fixture on the welding table to facilitate the welding operation. However, the structure of the existing fixing fixture is relatively simple, and it can only fix steel grating plates of the same specification size. It cannot be adjusted to fix steel grating plates of different specification sizes. When welding steel grating plates of different specification sizes, the corresponding fixing fixture needs to be replaced, which is rather troublesome to operate. As a result, not only the welding efficiency of the steel grating plates is reduced, but also the applicability of the fixing fixture during use is decreased. Summary of the Utility Model

[0009] Preferably, a first sliding opening is opened on the front end wall of the first clamping plate. The concave plate is fixedly installed on the outer side wall of the first clamping plate, and on the top surface and the bottom surface of the concave plate there are respectively opened second sliding openings.

Then, start the cylinder, and the driving output end drives the movable block to move outward, which will force the included angle between the symmetric connecting plates to gradually become smaller. During the changing process, the second clamping plates will be driven by the first sliders to move inward, and the symmetric second clamping plates will perform a relative moving operation until the front and rear ends of the steel grating are clamped and fixed between the second clamping plates according to the width of the steel grating. Thus, when welding the steel grating, the purpose of quickly fixing steel gratings of different specifications and sizes is achieved, which not only improves the welding efficiency of the steel grating, but also improves the applicability of the fixing fixture in use.

During the movement of the movable block 21 and driven by the connecting plate 27, the first slider 24 will slide in the first sliding opening 17.

The second sliders 22 installed on the top and bottom surfaces of the movable block 21 will slide in the second sliding openings 19 opened on the top and bottom surfaces of the concave plate 18. At this time, because the second rotating rods 28 installed on the top and bottom surfaces of both sides of the left and right symmetrical connecting plates 27 are respectively movably installed in the second rotating holes 26 opened on the top and bottom surfaces of the concave openings of the concave blocks 25 installed on one side of the movable block 21 and the rear end wall of the first slider 24, under the drive of the movement of the movable block 21, the second rotating rod 28 will rotate in the second rotating hole 26, and the connecting plate 27 will tilt. At the same time, the included angle formed between the left and right symmetrical connecting plates 27 will gradually become smaller. During this change process, the first slider 24 is driven by the concave block 25 on the first slider 24 to slide in the first sliding opening 17 opened on the front end wall of the first clamping plate 13, and the first slider 24 drives the second clamping plate 23 to move on the inner side wall of the first clamping plate 13.

Furthermore, not only the welding efficiency of the steel grating is improved, but also the applicability of the fixing fixture during use is improved.
