Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings:

example 1

As shown in fig. 1, the welding jig for the vacuum welding box comprises two discs 1 and a lower beam 2, wherein the lower beam 2 is fixed between the two discs 1 through bolts and a support frame 3 (refer to fig. 3), four guide pins 4 with the same size and the same height are fixed on the discs 1, clamping grooves are formed in two ends of an upper beam 5, and the upper beam 5 is connected with the discs 1 through the combination of the clamping grooves and the guide pins 4.

The lower beam 2 and the upper beam 5 are provided with a detachable first pressing plate 6 and a detachable second pressing plate 7, wherein the first pressing plate 6 and the second pressing plate 7 are positioned on two sides of the upper beam and the lower beam in an alternating arrangement.

The same open slots 8 (refer to fig. 2) are arranged at four corresponding groups of positions on the upper beam and the lower beam, baffle slots 9 are welded beside second pressing plates 7 at two sides of the lower beam 2 and used for placing baffles 10, a positioning plate 11 is also welded on a clamping platform of the lower beam 2, and the top of the upper beam 4 is provided with a lifting point 12.

And a disc on the other side opposite to the positioning plate 11 is provided with a jacking device, wherein the jacking device comprises a chuck 13 and a lead screw 14, the lead screw 14 penetrates through the disc and is rotatably connected with the disc, and the lead screw 14 is fixedly connected with the chuck 13.

The electrode block is clamped by the fixing of the open slot 8 and the bolt. Wherein the specific size of the clamp is determined by the size of the vacuum welding box and the size of the welding electrode block.

The working process is as follows: the electrode block is placed between the first pressing plate 6 and the second pressing plate 7 of the lower beam 2 and the baffle plate 10, and the placed electrode block is flat, straight and tightly attached in the length direction.

And then, after the upper beam 5 is connected with the disc 1 through the guide pin, bolts at two ends of the upper beam and the lower beam are screwed, the electrodes are clamped, and the baffle 10 is pulled out and enters a welding box for welding.
