[0050] Preferably, see Attachment Figure 2 Two third clamping blocks 20 are symmetrically arranged inside the two frames 16 .

[0051] Preferably, see Attachment Figure 2 Two pairs of movable plates 17 are fixedly provided on the outer sides of the two ends of the two frames 16, two stepping motors 19 are respectively provided on the outer sides of one of the frames 16, and two double-threaded screw rods 18 are respectively provided at the output ends of the two stepping motors 19, and the two ends of each double-threaded screw rod 18 are respectively in contact with the internal threads of the two relative movable plates 17.

[0052] Specific use of the present invention:

[0053] The staff place two metal products on two frames 16 respectively, and the staff controls the clamping assembly to start through the control box 12, and the two stepping motors 19 start to drive the two double-threaded screws 18 to rotate, and the two ends of the double-threaded screws 18 are respectively in contact with the internal threads of the two opposite moving plates 17, and the two threads at the two ends of the double-threaded screws 18 are in opposite directions, so that the rotation of the double-threaded screws 18 can drive the two moving plates 17 to move closer to each other or move away from each other. At this time, the two pairs of moving plates 17 approach each other and drive the two frames 16 to move closer to each other, and the two frames 16 approach each other and drive the two pairs of fixed frames 21 and the first guide blocks 22 to move closer to each other, so that one end of one pair of first guide blocks 22 enters the interior of the other pair of fixed frames 21, and one side of one pair of first guide blocks 22 contacts the inclined surface of one end of the other pair of push rods 24, so that each pair of slide plates 23 approaches each other. Each pair of slide plates 23 approaches each other, driving each pair of first hollow elastic members 28 and elastic rods 27 to approach each other, and each pair of elastic rods 27 approaches each other, driving each pair of first clamping plates 25 to approach each other, thereby clamping and fixing both sides of the metal product, so that two metal products can be clamped and fixed by two pairs of first clamping plates 25. Then, the distance between the sides of each pair of first clamping plates 25 that are close to each other gradually increases from top to bottom, so that the two first clamping plates 25 approach each other, causing a plurality of pairs of elastic protrusions 26 to approach each other, so that both sides of the metal product can be clamped and fixed, and downward pressure is generated on both sides of the metal product, so that the metal product can be clamped and fixed from top to bottom.

[0054] Next, each pair of slide plates 23 approaches each other, driving two pairs of second guide blocks 31 to approach each other, and one end of the second guide block 31 contacts the inclined surface of one end of the pressing plate 32, so that each pair of pressing plates 32 approaches each other. The two pressing plates 32 approach each other to squeeze the first hollow elastic member 28, so that the solution in the first hollow elastic member 28 enters the second hollow elastic members 29 through the first connecting tubes 34, and the second hollow elastic members 29 expand and push the connecting rods 30 and the elastic protrusions 26 to move downward. At this time, the clamping force on both sides of the metal product is increased by the mutual tilting downward movement of the pairs of elastic protrusions 26, and the clamping force on the upper and lower sides of the metal product is strengthened, so that the two metal products can be quickly aligned and contacted, and the displacement of the two metal products is avoided.

[0055] Then, each pair of first clamping plates 25 approach each other, driving each pair of pressing plates 32 to approach each other, and one end of the third guide block 39 is in an inclined structure, so that the two second water bags 40 are squeezed under the guiding and squeezing action of the two third guide blocks 39, so that the solution in the two second water bags 40 enters the two first water bags 35 through the two second connecting pipes 41, and the two first water bags 35 expand and push the two movable blocks 37 and the second clamping plates 38 to move downwardly, so that the lower side of the two second clamping plates 38 and the upper side of the metal product strengthen the clamping and fixing effect on the upper and lower sides of the metal product, and avoid displacement during the welding process of the two metal products. And the two frames 16 approach each other and drive the two third clamping blocks 20 to approach each other, so that the two metal products can be fully limited and fixed.

[0056] Finally, the staff controls the multi-axis linkage assembly 13 through the control box 12, so that the multi-axis linkage assembly 13 controls the precise position and movement path of the welding assembly 14 during the welding process, thereby improving the accuracy and efficiency of welding the two metal products.

[0057] The multi-axis linkage welding equipment for metal products of the present invention, through the arrangement of the fixed frame 21, the first clamping plate 25, the slide plate 23, the elastic rod 27, the first guide block 22, and the push rod 24, the two frames 16 approach each other to drive the two pairs of fixed frames 21 and the first guide blocks 22 to approach each other, so that one end of one pair of the first guide blocks 22 enters the interior of the other pair of fixed frames 21, and one side of one pair of the first guide blocks 22 is in contact with the inclined surface of one end of the other pair of push rods 24, so that each pair of slide plates 23 approaches each other. Each pair of slide plates 23 approaches each other to drive each pair of first hollow elastic members 28 and the elastic rod 27 to approach each other, and each pair of elastic rods 27 approaches each other to drive each pair of first clamping plates 25 to approach each other, so as to clamp and fix the two sides of the metal product, so that the two pairs of first clamping plates 25 can clamp and fix the two metal products respectively. Then, through the arrangement of the first hollow elastic member 28, the second hollow elastic member 29, the connecting rod 30, and the first connecting tube 34, each pair of slide plates 23 approaches each other to drive the two pairs of second guide blocks 31 to approach each other, and one end of the second guide block 31 contacts the inclined surface of one end of the pressing plate 32, so that each pair of pressing plates 32 approaches each other; the two pressing plates 32 approach each other to squeeze the first hollow elastic member 28, so that the solution in the first hollow elastic member 28 enters the second hollow elastic members 29 through the first connecting tubes 34 respectively, and the expansion of the second hollow elastic members 29 pushes the connecting rods 30 and the elastic protrusions 26 to move downward obliquely; through the mutual oblique downward movement of the pairs of elastic protrusions 26, the clamping force on both sides of the metal product is increased, and the clamping force on the upper and lower sides of the metal product is strengthened, so that the two metal products can be quickly aligned and contacted, and the displacement of the two metal products is avoided.

[0058] The multi-axis linkage welding equipment for metal products of the present invention gradually increases the distance between the sides of each pair of first clamping plates 25 that are close to each other from top to bottom, so that several pairs of elastic protrusions 26 are inclined downward to each other, so as to clamp and fix the two sides of the metal product, and generate downward pressure on the two sides of the metal product, so that the metal product can be clamped and fixed up and down. Through the arrangement of the movable frame 33, the push plate 36, the movable block 37, the second clamping plate 38, the third guide block 39, the second water bag 40 and the first water bag 35, each pair of first clamping plates 25 are brought closer to each other, driving each pair of pressure plates 32 to approach each other. One end of the third guide block 39 is in an inclined structure, so that the two second water bags 40 are squeezed under the guiding and squeezing action of the two third guide blocks 39, so that the solutions in the two second water bags 40 enter the two first water bags 35 through the two second connecting tubes 41. The expansion of the two first water bags 35 pushes the two movable blocks 37 and the second clamping plates 38 to move downwardly with respect to each other, so that the lower side of the two second clamping plates 38 and the upper side of the metal product strengthen the clamping and fixing effect on the upper and lower sides of the metal product, thereby avoiding displacement during the welding process of the two metal products.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
