A laser additive welding device

Abstract

This invention relates to the field of laser additive manufacturing technology and proposes a laser additive welding device, including a base, a support, a kit, a backing plate, a first pressing member, a second pressing member, a first support plate, and a second support plate. During the movement of the backing plate, with the bolt fixing the long rod inside the notch, the backing plate can simultaneously push the kit along the outer surface of the support via the long rod. This ensures that the welding head in the kit is always above the center position of the laser additive manufacturing process. Rotating the bolt to separate it from the threaded groove eliminates the limiting component on the long rod. With the long rod hinged to the auxiliary plate, it can freely rotate along the side of the auxiliary plate, thus preventing the long rod from contacting the side of the kit. This allows the kit to move freely on the outer surface of the support, solving the problem of difficulty in fine-tuning the position of the welding head in the kit for more precise laser additive welding.

[0026] like Figures 1-5 As shown, this embodiment proposes a laser additive welding device, including a base 1, a first sliding groove 11 on the upper end of the base 1, a bracket 2 fixedly connected to the upper end of one side of the base 1, a second sliding groove 21 on the inner side of the top of the bracket 2, a first blocking member 22 fixedly connected to one side of the upper end of the bracket 2, a gear 23 rotatably connected inside the bracket 2, a kit 3 slidably connected to the outer surface of the bracket 2, a bolt 4 provided on one side of the kit 3, a backing plate 5 slidably connected between the base 1 and the bracket 2, a first pressing member 6 provided on the inner side of the backing plate 5, a second pressing member 7 provided on the inner side of the bracket 2, the first pressing member 6 and the second pressing member 7 having the same structure, and a first support plate 8 and a second support plate 9 slidably connected to the side of the bracket 2.

[0027] Furthermore, the lower end of the kit 3 is fixedly connected to an extension block 31, and the lower end of the extension block 31 is fixedly connected to a welding head 311. A notch 32 is provided on one side of the lower end of the kit 3, and a threaded groove 321 is provided on the inner wall of the notch 32. The notch 32 is used to place the long rod 52, and the welding head 311 is used to weld the laser additive.

[0028] Furthermore, an auxiliary plate 51 is fixedly connected to the inner side of the abutment plate 5, and a long rod 52 is hinged to the inner side of the auxiliary plate 51. A through groove 521 is opened through one side of the long rod 52. A toothed plate 53 is also fixedly connected to the inner side of the abutment plate 5. One end of the long rod 52 is engaged with the notch 32. The through groove 521 is connected to the threaded groove 321. The lower end of the toothed plate 53 is engaged with the gear 23. The long rod 52 can rotate freely along the inner side of the auxiliary plate 51. The long rod 52 can push the kit 3 to move along the bracket 2.

[0029] Furthermore, the bolt 4 passes through the inside of the through slot 521 and is threaded into the threaded slot 321. The bolt 4 is used to fix the long rod 52 inside the notch 32.

[0030] Furthermore, the second pressing component 7 includes a horizontal plate 71 fixedly connected to the inner wall of the bracket 2. A vertical rod 72 is slidably connected through the interior of the horizontal plate 71. A handle 75 is fixedly connected to the upper end of the vertical rod 72, and a pressure plate 73 is fixedly connected to the lower end of the vertical rod 72. A spring 74 is fixedly connected to the lower end of the horizontal plate 71. The spring 74 is located around the vertical rod 72, and the lower end of the spring 74 is fixedly connected to the upper end of the pressure plate 73. The pressure plate 73 is used to press down and fix the upper end of the laser additive, and the spring 74 is used to push the pressure plate 73 down.

[0031] Furthermore, a second blocking member 83 is fixedly connected to one end of the first support plate 8, a first telescopic rod 81 is fixedly connected to one side of the other end of the first support plate 8, and a second telescopic rod 82 is fixedly connected to the other side of the other end of the first support plate 8. One end of the second telescopic rod 82 is fixedly connected to one side of the second support plate 9. One end of both the first support plate 8 and the second support plate 9 are slidably connected to the inner wall of the bracket 2. One end of the first telescopic rod 81 is fixedly connected to the side wall of the bracket 2. The second blocking member 83 is used to prevent the abutment plate 5 from detaching from the outer surface of the first support plate 8. The second telescopic rod 82 is used to push the second support plate 9 closer to or away from the first support plate 8. The first telescopic rod 81 is used to synchronously push the combination of the first support plate 8 and the second support plate 9 to move together.

[0032] The working principle and usage instructions of this invention are as follows: When welding is required for laser additive manufacturing, the operator first needs to adjust the distance between the first support plate 8 and the second support plate 9 according to the size of the laser additive. That is, the second support plate 9 is moved by pushing the second telescopic rod 82 until the relative distance between the first support plate 8 and the second support plate 9 is adjusted to a suitable position. Then, the laser material can be placed on the upper end of the combination of the first support plate 8 and the second support plate 9. Then, the gear 23 can be started. Under its rotation, the toothed plate 53 drives the abutment plate 5 to move closer to the support 2 until the abutment plate 5 forms abutment and compression on one side of the laser additive. At the same time, the other side of the laser additive is abutted and compressed by the inner side of the support 2, thereby forming an effective clamping and fixing on both sides of the laser additive. Under the action of the spring 74 pushing the pressure plate 73 downward, the pressure plate 73 can effectively press down and fix the upper end of the laser additive.

[0033] Furthermore, during the movement of the abutment plate 5, with the bolt 4 fixing the long rod 52 inside the notch 32, the abutment plate 5 can simultaneously push the kit 3 along the outer surface of the bracket 2 via the long rod 52, so that the welding head 311 in the kit 3 is always above the center position of the laser additive. When it is necessary to make a fine adjustment to the position of the kit 3 in order to weld the laser additive more accurately, the bolt 4 can be rotated to separate it from the threaded groove 321. At this time, the limiting component on the long rod 52 disappears. With the long rod 52 hinged to the auxiliary plate 51, the long rod 52 will rotate freely along the side of the auxiliary plate 51, so that the long rod 52 no longer abuts the side of the kit 3, and the kit 3 can move freely on the outer surface of the bracket 2.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
