Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment accessories, specifically a welding torch adjustment mechanism for laser-arc hybrid welding equipment. Background Technology

[0002] Laser-arc hybrid welding technology combines the advantages of laser welding and arc welding, which can significantly improve welding efficiency and quality. It has become an important processing method in aerospace, shipbuilding and other fields. In this technology, the positional accuracy of the welding torch directly affects the synergistic effect of the composite heat source. Therefore, the welding torch adjustment mechanism is one of the core components of the equipment. Existing laser-arc hybrid welding equipment is usually equipped with a welding torch adjustment mechanism, which realizes the vertical and horizontal position adjustment of the welding torch through a multi-directional displacement device and uses a clamping structure to fix the welding torch.

[0003] Currently, conventional welding torch adjustment mechanisms often rely on a single-direction clamping structure or manual adjustment device when clamping welding torches of different sizes. This can easily cause the welding torch to deviate during the combined vertical and horizontal adjustment process due to uneven distribution of clamping force. Especially when the welding torch adjustment mechanism is simultaneously adjusting in multiple directions, the existing clamping device is difficult to dynamically adapt to changes in the position of the welding torch. It is easy to cause welding path deviation due to unstable contact between the clamping surface and the welding torch, which seriously affects the synergistic effect of the composite heat source and the quality of weld formation.

[0004] In view of this, a welding torch adjustment mechanism for laser-arc hybrid welding equipment is proposed. Utility Model Content

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-4 .

[0028] The welding torch adjustment mechanism of this utility model laser-arc hybrid welding equipment includes a mounting base 1 and a bracket 11 fixedly connected to the mounting base 1. It also includes: an adjustment component 2, which is mounted on the mounting base 1 and includes a movable plate 21 that moves vertically relative to the mounting base 1 and a mounting plate 22 that moves horizontally relative to the movable plate 21. The mounting plate 22 has a mounting groove 221 for mounting the welding torch. The adjustment component 2 is used to adjust the position of the welding torch in the vertical and horizontal directions. A clamping component 3, which is mounted on the mounting plate 22, includes two first clamping plates 31 elastically disposed on the two side walls of the mounting groove 221 by springs 33, and two second clamping plates 32 slidably disposed at the top and bottom of the mounting groove 221. The clamping component 3 is used to clamp welding torches of different sizes to cooperate with the adjustment component 2 for adjustment.

[0029] Specifically, the clamping component 3 is used to clamp welding torches of different sizes, while the adjusting component 2 is used to adjust the position of the welding torch by moving the clamping component 3 in the horizontal and vertical directions.

[0030] Secondly, a first slide rod 23 is fixedly connected to the bracket 11, and the first slide rod 23 passes through the movable plate 21. A first motor 26 is fixedly connected to the bottom of the bracket 11, and a first screw 24 is fixedly connected to the output end of the first motor 26. The top of the first screw 24 is rotatably connected to the bracket 11. A first threaded sleeve 25 is connected to the first screw 24 through a ball screw thread. The first threaded sleeve 25 is fixedly connected to the movable plate 21. This arrangement, through the cooperation structure of the cross-shaped slider and the slide groove, enhances the guiding rigidity and anti-torsional ability of the horizontal movement of the mounting plate 22 by increasing the contact surface, thus preventing the mounting plate 22 from... The electric push rod 27 drives the tilting or shaking. This configuration, through the composite design of the first slide rod 23 and the first screw 24, not only provides guiding constraints for the vertical lifting of the movable plate 21, but also achieves high-precision, low-friction linear drive through the ball screw pair thread pair, ensuring the stability and positioning accuracy of the welding torch when adjusting in the vertical direction. During installation, the two ends of the first slide rod 23 need to be fixed to the top and bottom of the bracket 11 respectively to ensure that it is parallel to the first screw 24. The first motor 26 drives the first screw 24 to rotate through the coupling, which drives the first screw sleeve 25 and the movable plate 21 to move along the first slide rod 23.

[0031] During implementation, the first slide bar 23 and the first screw 24 need to be lubricated regularly. During the first commissioning, the matching relationship between the motor stroke and the displacement of the movable plate 21 needs to be calibrated to avoid overload or jamming.

[0032] Furthermore, a first slider 28 with a cross-shaped cross section is fixedly connected to the mounting plate 22, and a first groove 29 adapted to the size of the first slider 28 is provided on the movable plate 21. An electric push rod 27 is fixedly connected to the bottom of the movable plate 21, and the extended end of the electric push rod 27 is fixedly connected to the mounting plate 22. This arrangement can enhance the guiding rigidity and anti-torsion ability of the horizontal movement of the mounting plate 22 by increasing the contact surface through the cooperation structure of the cross-shaped slider and the groove, and prevent the mounting plate 22 from tilting or shaking under the drive of the electric push rod 27.

[0033] In addition, both ends of the two second clamping plates 32 are fixedly connected to second sliders 38 with a cross-shaped cross section. The mounting plate 22 has multiple second grooves 39 that are adapted to the size of the multiple second sliders 38. Specifically, by setting cross-shaped sliders and multiple symmetrically distributed second grooves 39 at both ends of the second clamping plates 32, the clamping plates are subjected to uniform force when moving, avoiding single-point stress concentration that may cause jamming, and improving the synchronization and smoothness of the clamping action.

[0034] In addition, a second slide rod 34 is fixedly connected to the mounting plate 22, passing through the two second clamping plates 32. A second motor 37 is fixedly connected to the mounting plate 22. A second screw 35 is fixedly connected to the output end of the second motor 37. The second screw 35 is rotatably connected to the mounting plate 22. The threads at both ends of the second screw 35 are reversed. Both ends of the second screw 35 are connected to a second screw sleeve 36 through a ball screw pair thread. The two second screw sleeves 36 are fixedly connected to the two second clamping plates 32 respectively. That is to say, the composite drive system composed of the reverse-threaded second screw 35 and the second slide rod 34 enables the two second clamping plates 32 to move synchronously in opposite directions, achieving symmetrical clamping when the clamping distance is reduced, and avoiding horizontal deflection of the welding torch due to unilateral force.

[0035] Furthermore, the second slide bar 34 and the second screw 35 are respectively disposed on both sides of the second clamping plate 32. By placing the slide bar and the screw on both sides of the clamping plate, a mechanically balanced layout is formed. The slide bar provides guiding support, and the screw applies tension or thrust, reducing the risk of deformation when subjected to force on one side.

[0036] Furthermore, the minimum distance between the two second clamping plates 32 is greater than the length of the two first clamping plates 31. This arrangement ensures that the second clamping plates 32 will not obstruct the clamping area of ​​the first clamping plates 31 when fully retracted, thus avoiding mechanical interference between the two types of clamping mechanisms at extreme positions and ensuring compatibility of welding torches of different diameters.

[0037] Working principle:

[0038] The welding torch adjustment mechanism achieves precise positioning and stable fixation of the welding torch through a combination of vertical and horizontal movements and multi-directional clamping. Specifically, in the adjustment component 2, the first motor 26 drives the first screw 24 to rotate, causing the first screw sleeve 25 and the movable plate 21 to move vertically along the first slide rod 23, thereby adjusting the height of the welding torch. The electric push rod 27 pushes the mounting plate 22 to move horizontally along the guide structure of the cross-shaped slider and the slide groove, completing the horizontal position adjustment of the welding torch. In the clamping component 3, the second motor 37 drives the second screw 35 with a reverse thread to rotate, causing the two second clamping plates 32 to slide synchronously in the opposite direction along the second slide bar 34. In conjunction with the spring 33, the first clamping plate 31 is elastically clamped, forming a four-sided adaptive clamping of the welding gun from the top, bottom and sides. During vertical and horizontal adjustment, the high-rigidity guide structure of the cross-shaped slider and the slide groove suppresses the offset, while the combination design of the bidirectional screw and the slide bar ensures the symmetry of the movement of the clamping plate. Ultimately, the welding gun is positioned and clamped with high precision under multi-directional dynamic adjustment, adapting to welding guns of different sizes and complex welding path requirements.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
