Detailed Embodiment
[0021] Referring to Figures 1-4 As shown, a welding clamp for reducing the repair welding rate of an aluminum alloy product includes a left pushing block 2, a right pushing block 3, a first clamping plate 10 and a second clamping plate 16. The left pushing block 2 and the right pushing block 3 abut against both ends of the first clamping plate 10 and the second clamping plate 16. When the aluminum alloy product 1 is welded, the aluminum alloy product 1 is placed between the first clamping plate 10 and the second clamping plate 16. The left pushing block 2 and the right pushing block 3 move inward, and the first clamping plate 10 and the second clamping plate 16 squeeze the aluminum alloy product 1 inward, and the aluminum alloy product 1 is stressed to prevent the aluminum alloy product 1 from shifting left and right and front and back.
[0022] In this embodiment, the aluminum alloy product is an energy absorption box. The inner shape of the first clamping plate 10 and the second clamping plate 16 can be changed according to the outer contour of the aluminum alloy product, so that the space between the first clamping plate 10 and the second clamping plate 16 corresponds to the outer contour of the aluminum alloy product, forming an effect of restricting the offset of the aluminum alloy product.
[0023] The rear ends of the left pushing block 2 and the right pushing block 3 are connected to the pushing plate 11. The rear end of the pushing plate 11 is connected to the output rod of the cylinder 12. The left and right movement of the output rod of the cylinder 12 drives the pushing plate 11 to move, and the left and right movement of the pushing plate 11 drives the left pushing block 2 and the right pushing block 3 to move left and right.
[0024] The left pushing block 2 and the right pushing block 3 are L-shaped. The front end of the left pushing block 2 includes a first pushing arm 13 and a second pushing arm 14. An outwardly extending pushing claw 9 is formed on the second pushing arm 14. The pushing claw 9 expands outward. The pushing claw 9 is in contact with the first clamping plate 10. The pushing claw 9 moves towards the first clamping plate 10 to form a clamping force to prevent the aluminum alloy product 1 inside the first clamping plate 10 from moving left and right or forward and backward. When the pushing claw 9 is in contact with the first clamping plate 10, it gives the first clamping plate 10 a pushing force towards the inside. The right pushing block 3 gives the first clamping plate 10 a pushing force towards the left and towards the inside. Thus, a pushing force is formed to prevent the aluminum alloy product 1 inside the first clamping plate 10 from moving left and right or forward and backward.
[0025] The first clamping plate 10 is adapted to the edge of the aluminum alloy product 1 to form a clamping effect to prevent the aluminum alloy product 1 from moving forward and backward or left and right.
[0026] The second clamping plate 16 is adapted to the other edge of the aluminum alloy product 1 to form a clamping effect to prevent the aluminum alloy product 1 from moving forward and backward or left and right. A clamping claw 15 is formed outwardly on the first pushing arm 13. The clamping claw 15 abuts against the second clamping plate 16 to prevent the second clamping plate 16 from moving forward and backward or left and right.
[0027] It further includes a front supporting block 8 and a rear supporting block 4. The front end of the front supporting block 8 is connected to the second clamping plate 16, and the front end of the rear supporting block 4 is connected to the first clamping plate 10. It further includes a first cylinder 17 connected to the front supporting block 8 and a second cylinder 6 connected to the rear supporting block 4. The first cylinder 17 and the second cylinder 6 are vertically arranged. The output shafts 7 of the first cylinder 17 and the second cylinder 6 are connected to the front supporting block 8 and the rear supporting block 4, and their up and down movements drive the front supporting block 8 and the rear supporting block 4 to move, thereby driving the first clamping plate 10 and the second clamping plate 16 to move.
[0028] The front supporting block 8 and the rear supporting block 4 are arranged around the aluminum alloy product 1 to reduce the amount. When the aluminum alloy product 1 is welded, the left pushing block 2 and the right pushing block 3 are clamped on the left and right sides of the aluminum alloy product 1, and the front supporting block 8 and the rear supporting block 4 are located below the aluminum alloy product 1 to prevent the aluminum alloy product 1 from shifting downward when being welded. The front supporting block 8 and the rear supporting block 4 play a role of upward extrusion and lifting for the aluminum alloy product 1.
[0029] A pressing plate 5 is further provided, and the pressing plate 5 is located above the aluminum alloy product 1.
[0030] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
