Abstract

PURPOSE:To enable easy lap welding to the front end of the 1st object to be welded without opening the spacing between a backing strip and a clamper so much by lifting the front end of the 2nd object to be welded by means of a lifting guide via a vertical driving mechanism. CONSTITUTION:An object 7 to be welded is clamped to a backing strip 1 by a clamper 2, whereafter a clamper 3 is opened by a pressurization mechanism 5 to open the spacing between the strip 1 and the bottom surface of the clamper 3 so far the bottom surface of the clamper 3 becomes higher than the height as much as the sum of the height of an object 8 to be welded and the height at the front end of the object 7. While a lifting guide 11 is held raised to about the same as the height at the front end of the object 7 or the position slightly higher than the same by a vertical driving mechanism 10, the front end of the object 8 is inserted from the side. Then the front end of the object 8 overlaps automatically on the front end of the groove 9 for welding through the top surface of the guide 11. The guide 11 is lowered from the surface of the strip 1 while the front ends are superposed, then the object 8 is clamped onto the strip 1 by the clamper 3 and both objects are welded by a welding torch 6.

After welding is completed f, loosen the pressure mechanisms 4 and i], remove the clampers 2 and 3, and -C, remove the welded objects 7 and 8. .

However, with such conventional equipment, even if the tip of the workpiece 6 is inserted from the side between the backing metal 1 and the clamper 3, the workpiece generally remains as shown in Figure 1 U. There is a wrinkle in the J-piece, insert-J-rutage, υJ, object to be welded 7
The disadvantage is that the tip of the 9th day is slightly difficult to reach. Also, to make it easier to overlap, use backing metal 1 and clamper 3.
The distance between the two must be sufficiently wide.

The present invention solves these conventional drawbacks and provides a lap welding device that allows the tip of the work piece to be easily clamped without having to widen the gap between the backing metal and the clamper. The proposition, J.

FIG. 2 is a city view showing an example of the configuration of the claw welding device according to the present invention. 1 to 9 in the figure are the same parts as in the case of Figure 1. 10 is a drive mechanism that moves the upper push-up guide 1 upward; 11 is a push-up guide that is close to the tip of the workpiece 8 and pushes up one part higher than the height of the other workpiece 7; It is.

Therefore, according to the present invention (from ``C'' and ``Kiguzenoa 6'' 4), even in the case of grilled food, simply inserting from the drawing will ensure reliable overlapping. There is no need to open the gap too widely, and automatic welding can be carried out easily and quickly.

In other words, when the upper surface of the push-up guide 11 is held at the same height as the upper surface of the workpiece 7 by the coil/brake 12, and when the workpiece B is also clamped by the clamper 3, the clamper 3 The push-up guide 11 is also pushed down by the rotating portion by the push-up force.
