Description

Technical Field

[0001] This application relates to the technical field of welding equipment, and in particular to an auxiliary metal welding device for stacker vehicles. Background Technology

[0002] Forklifts play a vital role in modern logistics handling operations. The welding quality of their metal structural components directly affects the overall performance and safety of the forklift. During the welding process of the metal parts of the forklift, it is often necessary to precisely splice and weld metal plates, pipes and other materials of different shapes and sizes.

[0003] Regarding the aforementioned related technologies, the inventors believe that in the prior art, when welding metal parts, workers usually manually hold the two sets of parts to be welded, which can easily lead to positional misalignment during the welding process. Furthermore, since the two parts have concave and convex parts that correspond to each other, the welding device generally does not have an angle adjustment function, which cannot ensure that the parts to be welded are fully aligned, thus affecting the welding effect. Therefore, in order to solve the above problems, this application provides an auxiliary metal welding device for stacker vehicles. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides an auxiliary metal welding device for stacker vehicles.

[0005] This application provides an auxiliary metal welding device for stacker vehicles, comprising a base, an L-shaped plate, an upper clamping assembly, and a lower clamping assembly. A servo motor is fixedly connected to the surface of the base, and a worm gear is fixedly connected to the output end of the servo motor via a coupling. A worm wheel meshes with the outside of the worm gear, and a rotating shaft is fixedly connected inside the worm wheel. An adjusting disc is fixedly connected to the top of the rotating shaft. A first electric telescopic rod is fixedly connected to the top inner wall of the L-shaped plate, and a fixed disc is fixedly connected to the output end of the first electric telescopic rod. A transverse groove is formed at the bottom of the fixed disc.

[0006] Preferably, the lower clamping assembly includes three second electric telescopic rods that are fixedly connected to the bottom of the adjusting plate at equal intervals and in a radiating pattern, and the output ends of the three second electric telescopic rods are all fixedly connected to a second clamping plate.

[0007] Preferably, the upper clamping assembly includes a drive motor fixedly connected to the inner wall of one end of the transverse groove. The output end of the drive motor is fixedly connected to a bidirectional screw via a coupling. The external threads of the bidirectional screw are symmetrically connected to two sliders, and the bottom of each of the two sliders is fixedly connected to a first clamping plate.

[0008] Preferably, the bottom end of the rotating shaft is rotatably connected to the base.

[0009] Preferably, a fixing block is rotatably connected to the end of the worm gear away from the servo motor, and the fixing block is fixedly connected to the outside of the base.

[0010] Preferably, the L-shaped plate is fixedly connected to the outside of the base.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] The lower clamping assembly clamps and fixes the lower part, while the upper clamping assembly fixes the upper part. By activating the servo motor, the servo motor, worm gear, worm wheel, and rotating shaft work together to rotate the top adjustment plate, thereby adjusting the angle of the lower part on the adjustment plate surface. Activating the first electric telescopic rod moves the fixing plate and the upper part toward the lower part. Compared to existing technologies, this application, by adjusting the angle of the lower clamping assembly, facilitates the alignment of the weld joints between two components, improving the welding effect.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A stacker vehicle auxiliary metal welding device, referring to Figure 1 - Figure 4The system includes a base 1, an L-shaped plate 2, an upper clamping assembly, and a lower clamping assembly. A servo motor 3 is fixedly connected to the surface of the base 1. The output end of the servo motor 3 is fixedly connected to a worm gear 4 via a coupling. A worm wheel 5 meshes with the outside of the worm gear 4. A rotating shaft 6 is fixedly connected inside the worm wheel 5. An adjusting plate 7 is fixedly connected to the top of the rotating shaft 6. A first electric telescopic rod 8 is fixedly connected to the top inner wall of the L-shaped plate 2. A fixed plate 9 is fixedly connected to the output end of the first electric telescopic rod 8. A horizontal groove 10 is provided at the bottom of the fixed plate 9. When the servo motor 3 is started, the servo motor 3 drives the worm gear 4 to rotate. The rotation of the worm gear 4 drives the worm wheel 5 to rotate. The rotation of the worm wheel 5 drives the rotating shaft 6 inside to rotate. The rotation of the rotating shaft 6 drives the adjusting plate 7 on top to rotate, thereby adjusting the angle of the part below the surface of the adjusting plate 7. When the first electric telescopic rod 8 is started, the first electric telescopic rod 8 drives the fixed plate 9 and the upper part to move towards the lower part. Through the adjustment action of the lower clamping assembly, it is easy to align the welded joints between the two parts.

[0021] Reference Figure 2 and Figure 4 The lower clamping assembly includes three second electric telescopic rods 11 that are fixedly connected to the bottom of the adjusting plate 7 at equal intervals and in a radiating pattern. The output ends of the three second electric telescopic rods 11 are all fixedly connected to second clamping plates 12. When the lower part is placed between the three second clamping plates 12, the three second electric telescopic rods 11 are activated, and the second electric telescopic rods 11 work to drive the three second clamping plates 12 to move toward the lower part, thereby achieving clamping and fixing of the lower part.

[0022] Reference Figure 3 The upper clamping assembly includes a drive motor 13 fixedly connected to the inner wall of one end of the transverse groove 10. The output end of the drive motor 13 is fixedly connected to a bidirectional screw 14 via a coupling. Two sliders 15 are symmetrically threaded to the outside of the bidirectional screw 14. The bottom of each slider 15 is fixedly connected to a first clamping plate 16. When the drive motor 13 is started, the drive motor 13 drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 will cause the two sliders 15 and the first clamping plate 16 to move closer to each other. At least one outer wall of the slider 15 is tightly fitted to the inner wall of the transverse groove 10. The two first clamping plates 16 moving closer to each other can fix the upper part.

The first electric telescopic rod 8, the second electric telescopic rod 11, the drive motor 13, and the servo motor 3 are all electrically connected to an external power supply via a switch. The lower part is placed between three second clamping plates 12. The three second electric telescopic rods 11 are activated by the switch, causing the three second clamping plates 12 to move towards the lower part, thus clamping and fixing the lower part. The drive motor 13 is activated by the switch, causing the bidirectional screw 14 to rotate. The two sides of the bidirectional screw 14 have opposite thread directions, equal pitch, and a helix opening angle of 20 degrees. The thread self-locking condition can be achieved through the following... Formula calculation: Self-locking condition = friction coefficient × tan (helix angle) ≥ 1. The rotation of the bidirectional screw 14 will drive the two external sliders 15 and the first clamping plate 16 to move closer to each other. The inner wall of at least one outer wall of the slider 15 is tightly fitted. The two first clamping plates 16 can fix the upper part by moving closer to each other. The servo motor 3 is started by the switch. The servo motor 3 drives the worm 4 to rotate. The rotation of the worm 4 drives the external worm wheel 5 to rotate. The rotation of the worm wheel 5 drives the internal rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the top adjustment plate 7 to rotate, so that the angle of the part under the surface of the adjustment plate 7 can be adjusted. The first electric telescopic rod 8 is started by the switch. The first electric telescopic rod 8 drives the fixed plate 9 and the upper part to move towards the lower part. Through the adjustment of the lower clamping assembly, it is easy to align the welded joints between the two parts.
