Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a truss-type welding device. Background Technology

[0002] Welding is a forming method that uses heat or pressure, or both, to create interatomic bonding forces between two separate objects, thus joining them into one. Based on the degree of heating and process characteristics, welding methods can be divided into three main categories: fusion welding, pressure welding, and brazing.

[0003] In some welding processes, especially in construction sites, the position of the parts to be welded is often moved and adjusted manually. This repeated adjustment process can easily affect the accuracy and efficiency of the welding.

[0004] To address the aforementioned problems, we propose a truss-type welding device. Utility Model Content

[0022] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0023] Example: Refer to Figure 1 - Figure 4 As shown, a truss welding device in this embodiment includes a support frame 2, a slide rail 1 is provided at the middle of the upper end of the support frame 2, and a slider 3 is slidably installed on the slide rail 1. The slide rail 1 and the slider 3 are mainly driven by a synchronous belt to ensure the accuracy of their sliding motion. This is a mature existing technology and will not be described in detail.

[0024] A laser welding gun 4 is mounted on the slider 3; a welding table 5 is provided at the bottom of the laser welding gun 4, and a movable plate 6 is slidably mounted on the upper middle part of the welding table 5. Support columns 13 are provided on both sides of the upper end of the movable plate 6, and chucks 14 are installed on the inner end face of the support columns 13. A drive assembly is provided at the bottom of the two sets of support columns 13. The drive assembly is used to drive the two sets of support columns 13 to perform horizontal reciprocating sliding motion. The drive assembly includes a reciprocating screw 11, which is rotatably mounted on the inner middle part of the movable plate 6 and driven by a second motor 12. The two sets of support columns 13 are respectively movably mounted on the middle of both ends of the reciprocating screw 11. The chucks 14 are used to clamp and fix the plate-shaped parts to be welded. Then, by rotating the reciprocating screw 11, the two sets of support columns 13 slide closer to each other or further away from each other.

[0025] An adjustment component is provided at the bottom center of the movable plate 6. The adjustment component is used to drive the movable plate 6 to slide horizontally. The adjustment component includes a ball screw 7, which is movably installed at the bottom center of the welding table 5. A sliding block 9 is slidably installed on the ball screw 7. The sliding block 9 is fixedly installed at the bottom center of the movable plate 6. By rotating the ball screw 7, the sliding block 9 drives the movable plate 6 to slide horizontally in the X-axis direction.

[0026] In some examples, the second motor 12 is connected to the right end of the reciprocating lead screw 11. The second motor 12 is fixedly installed in the middle of the right end of the movable plate 6. Starting the second motor 12 can drive the reciprocating lead screw 11 to rotate.

[0027] In some examples, a first motor 8 is provided at the middle of the right end of the ball screw 7. The first motor 8 is fixedly installed on the right side of the bottom end of the welding table 5. Starting the first motor 8 can drive the ball screw 7 to rotate.

[0028] In some examples, support blocks 10 are provided at the middle of both ends of the ball screw 7. The support blocks 10 are fixedly installed on both sides of the bottom end of the welding table 5. The support blocks 10 play a role in stabilizing the installation and rotation of the ball screw 7.

[0029] The working principle of this utility model is as follows:

[0030] During use, the two parts to be welded are first installed in the chucks 14 on both sides of the upper end of the movable plate 6. Then, the second motor 12 is started to drive the reciprocating screw 11 to rotate, so that the two sets of support columns 13 slide closer to each other until the two parts to be welded are in contact.

[0031] At this time, the first motor 8 is started again, driving the ball screw 7 to rotate, causing the sliding block 9 to drive the movable plate 6 to slide in the X-axis direction, thereby adjusting the position of the welding point of the two parts, so that the welding point is moved to the position directly below the laser welding gun 4. Then, the laser welding gun 4 is started again to weld the two parts. In addition, during the welding process, the slider 3 slides on the slide rail 1, causing the laser welding gun 4 to move in the Y-axis direction, so that the welding area can be increased when processing the sheet metal parts.

[0032] In this invention, the position of the laser welding gun 4 can be adjusted in the Y-axis direction by sliding the slider 3 on the slide rail 1. The first motor 8 drives the ball screw 7 to rotate, so that the sliding block 9 can drive the movable plate 6 and the two sets of parts to be welded clamped and fixed above the movable plate 6 to slide in the X-axis direction, thereby effectively improving the accuracy and efficiency of welding the sheet metal parts.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
