Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4As shown, a pulse laser welding device proposed in one embodiment of the utility model includes a base 1, an adjusting frame 2, a hydraulic cylinder 3, a rotating disk 4, a clamping disk 5 and a clamping piece 6. The pulse laser welding device designed in this scheme optimizes the design of the placement table for the welding parts on the basis of the existing pulse laser welding machine, so as to solve the problems that the connection efficiency of the traditional placement table is slow when taking and placing materials, affecting the welding efficiency, and the traditional placement table cannot be conveniently adjusted to be suitable for clamping and fixing welding parts of different sizes. The base 1 is provided with an adjusting frame 2, the bottom of the adjusting frame 2 is fixedly connected to the piston rod of the hydraulic cylinder 3, the hydraulic cylinder 3 is limited and rotatably connected in the base 1, the adjusting frame 2 is symmetrically rotatably connected with the rotating disk 4, and the rotating disk 4 is fixedly connected with a clamp The holding plate 5 is provided with a clamping member 6, and the device is electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. The four corners of the bottom of the adjustment frame 2 are fixedly connected with positioning pins, and the four corners of the top of the base 1 are provided with connecting holes. The direction of the adjustment frame 2 on the base 1 can be kept fixed by plugging the positioning pins and the connecting holes. When the welded part is subjected to pulse laser welding, the welded part is placed on the clamping plate 5, and then the hexagonal holes at any end of the first adjusting rod 601 and the second adjusting rod 603 are plugged and rotated, so that the first adjusting rod 601 and the second adjusting rod 603 can be rotated and adjusted, so that the first clamping block 601 and the second adjusting rod 603 can be adjusted respectively. 2 and the second clamping block 604 are adjusted to make the first clamping block 602 and the second clamping block 604 slide and adjust in the first slide groove 501 and the second slide groove 502 respectively, so as to control the intermediate distance between the first clamping block 602 and the second clamping block 604, meet the clamping use of welding parts of different sizes, improve the use effect of convenient clamping and fixing, and when one welding part is being welded, the next welding part to be welded can be clamped and fixed. Since the rotating disk 4 at the position of the welding part currently being welded is under the pulse laser welding machine, the rotating disk 4 on the other side is in a safe position on one side of the pulse laser welding machine, which is convenient for the operator to clamp and fix the welding part. After the previous welding part is welded, the rotating disk 4 is opened by liquid welding. The hydraulic cylinder 3 extends out to raise the adjusting frame 2 as a whole.

By rotating the rotating disk 4, the welding parts placed on the clamping disk 5 can be welded at multiple angles.

[0028] like Figure 4 As shown, in some embodiments, the clamping plate 5 is provided with a first slide groove 501 and a second slide groove 502 which are cross-staggered and the depth of the second slide groove 502 is greater than the depth of the first slide groove 501 , and the clamping plate 5 meets the connection and adjustment requirements of the clamping member 6 .

[0029] like Figure 4As shown, in some embodiments, the clamping member 6 is composed of a first adjusting rod 601, a first clamping block 602, a second adjusting rod 603 and a second clamping block 604. The first adjusting rod 601 is rotatably connected in the first slide groove 501, and both ends of the first adjusting rod 601 are threadedly connected to the first clamping block 602, and the first clamping block 602 is slidably connected in the first slide groove 501.
