Description

Technical Field

[0001] This utility model relates to the field of bubbling platform technology, and in particular to a bubbling platform for laser welding. Background Technology

[0002] Laser welding refers to the welding method that uses a laser. Through laser welding, two or more workpieces can be welded together. During laser welding, a bubbling platform can be used to press and fix the workpieces, thereby completing the laser welding work in conjunction with the laser welding equipment.

[0003] When welding plate-shaped parts, the parts are first placed on a bubbling platform, and then the clamping device on the bubbling platform is moved to clamp the top edge of the parts to prevent them from shifting during welding. However, the existing clamping devices on the bubbling platform generally have multiple clamping heads on a moving plate. Moving the moving plate moves the multiple clamping heads as a whole, and each clamping head cannot move independently. This means that the clamping device can only clamp plate-shaped parts with flat edges, such as cubes or cuboids, and cannot clamp plate-shaped parts with irregular edges. It has poor flexibility and a limited range of applications. Utility Model Content

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0041] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Please refer to Figures 1-6 The present invention provides a bubbling platform for laser welding, comprising a platform body 1, a fixed pressing mechanism 2, a movable pressing mechanism 3 and a guiding mechanism 4, wherein multiple sliding grooves 11 are opened horizontally on the top of the platform body 1, and the multiple sliding grooves 11 are arranged in parallel at equal intervals along the longitudinal direction.

[0043] The fixed clamping mechanism 2 includes multiple sets of first clamping components 21 fixedly installed on the top of the platform body 1. The multiple sets of first clamping components 21 are arranged at equal intervals along the longitudinal direction and are used to clamp the neat edges of the workpiece to be welded.

[0044] The movable clamping mechanism 3 includes multiple sets of movable components 31, which are arranged one-to-one with multiple slides 11. The movable components 31 are slidably connected to the slides 11. A second clamping component 32 is rotatably arranged on the top of the movable component 31. The movable component 31 can drive the second clamping component 32 to move along the length direction of the slide 11, which is used to clamp the irregular edges of the workpiece to be welded.

[0045] Specifically, when pressing a plate-shaped structure with an irregular edge, the irregular edge is placed towards the moving pressing mechanism 3. The first pressing component 21 on the fixed pressing mechanism 2 presses the top of the neat edge of the workpiece. Then, the moving component 31 is moved according to the shape of the irregular edge of the workpiece. The moving component 31 is manually pushed and slides in the slide groove 11 to a position close to the irregular edge of the workpiece. Then, the second pressing component 32 is rotated so that it presses the top of the workpiece. By setting multiple sets of moving components 31, it is convenient to adjust the moving position of the corresponding second pressing component 32 individually, so that it can better press the edge shape of the workpiece, improve the flexibility of the device adjustment, and increase the applicability of the device.

[0046] Preferred, such as Figure 2 , Figure 3 and Figure 4 As shown, the movable component 31 includes a movable plate 311, a mounting frame 312 is fixedly provided at the bottom of the movable plate 311, a roller 313 is rotatably mounted on the mounting frame 312, the roller 313 is tumbledly connected to the slide groove 11, and sliders are symmetrically provided on both sides of the mounting frame 312, the sliders are slidably connected to the slide groove 11.

[0047] Specifically, the movement of the movable plate 311 is achieved by setting the roller 313 and the slider; and the slider is embedded in the inner wall of the slide groove 11 and achieves sliding connection. The setting of the slider improves the stability of the device and prevents the roller 313 from dislodging from the slide groove 11.

[0048] Preferred, such as Figure 2 , Figure 3 and Figure 4 As shown, an auxiliary plate 314 is symmetrically arranged at the bottom of the movable plate 311 about the mounting bracket 312. A ball bearing 315 is embedded at the bottom of the auxiliary plate 314, and the ball bearing 315 contacts the top of the platform body 1.

[0049] Specifically, the ball bearings 315 reduce friction and improve the flexibility of the moving plate 311 during movement.

[0050] Preferred, such as Figure 2 , Figure 3 and Figure 4 As shown, positioning holes 3111 are provided at the four corners of the movable plate 311. Multiple sets of positioning components corresponding to the positioning holes 3111 are provided on the top of the platform body 1 along the horizontal direction. The positioning components include multiple positioning grooves 12 that are equally spaced along the horizontal direction. The positioning holes 3111 and the positioning grooves 12 are connected by the first bolt thread 316.

[0051] Specifically, the movable plate 311 is fixed to the top of the platform body 1 by the first bolt 316 to prevent it from moving during the pressing of the workpiece and to improve the stability of the device; and the bolt connection structure is simple and easy to implement and convenient to operate.

[0052] Preferred, such as Figure 2 As shown, the second clamping assembly 32 includes a fixed base 321, a rotating column 322, a second mounting plate 323, a second hydraulic cylinder 324, and a second pressure plate 325. The fixed base 321 is fixedly disposed on the top of the movable plate 311, and the rotating column 322 is rotatably disposed on the top of the fixed base 321. Specifically, the rotating column 322 and the fixed base 321 can be rotatably connected by bearings. The second mounting plate 323 is fixedly disposed on the top of the rotating column 322, and the second hydraulic cylinder 324 is fixedly mounted on the second mounting plate 323. The piston end of the second hydraulic cylinder 324 is disposed downward and fixedly connected to the second pressure plate 325. Specifically, before clamping, the piston end of the second hydraulic cylinder 324 retracts to facilitate the placement of the workpiece at the bottom of the second pressure plate 325. When the second clamping assembly 32 moves to the workpiece to clamp it, the piston end of the second hydraulic cylinder 324 extends, causing the second pressure plate 325 to descend and clamp the workpiece.

[0053] Preferably, a rotating frustum 326 is fixedly sleeved at the bottom of the rotating column 322, and a fixed frustum 327 is fixedly sleeved at the top of the fixed seat 321. The rotating frustum 326 has a locking hole, and the fixed frustum 327 has multiple adjusting holes evenly arranged along its circumference, corresponding to the locking hole. The locking hole and the adjusting holes are threadedly connected by a second bolt 328. Specifically, when the second clamping assembly 32 moves to the irregular edge of the workpiece, the rotating column 322 can be manually rotated, thereby causing the second pressure plate 325 to rotate along the horizontal plane, positioning the second pressure plate 325 above the top of the workpiece, allowing for better alignment and clamping of the workpiece. After the second pressure plate 325 is adjusted to the appropriate position, the rotating frustum 326 and the fixed frustum 327 are fixed by the second bolt 328 to prevent the second hydraulic cylinder 324 from shaking during the clamping process.

[0054] Preferred, such as Figure 4 and Figure 5 As shown, two adjacent movable plates 311 are detachably connected by a connecting component 33.

[0055] Preferred, such as Figure 5 As shown, the connecting component 33 includes a first connecting portion 331 and a second connecting portion 332 symmetrically arranged on both sides of the movable plate 311. The second connecting portion 332 is slidably connected to the top of the movable plate 311. Specifically, a slider is provided at the bottom of the second connecting portion 332, and a groove is provided on the top of the movable plate 311 along the longitudinal direction. The slider is slidably connected to the groove. Preferably, an opening is provided on the side of the first connecting portion 331 opposite to the second connecting portion 332. The opening is used to allow the second connecting portion 332 on the adjacent movable plate 311 to be inserted.

[0056] The first connecting part 331 has a first fixing hole, and the second connecting part 332 has a second fixing hole. The first fixing hole and the second fixing hole are connected by a third bolt 333.

[0057] Specifically, when clamping a workpiece with regular edges, such as a cube or cuboid, the second connecting part 332 can be moved to insert into the first connecting part 331 on the adjacent moving plate 331. Then, the first connecting part 331 and the second connecting part 332 are fixed by the third bolt 333, thereby splicing multiple moving components 31 into a whole. This allows the workpiece with neat edges to move as a whole when clamping, avoiding the need to move individual moving components 31 and improving the convenience and flexibility of operation.

[0058] Preferred, such as Figure 2As shown, the first clamping assembly 21 includes a bracket 211, a first mounting plate 212, a first hydraulic cylinder 213, and a first pressure plate 214. The bracket 211 is fixedly mounted on the top of the platform body 1, the first mounting plate 212 is fixedly mounted on the top of the bracket 211, and the first hydraulic cylinder 213 is fixedly mounted on the first mounting plate 212. The piston end of the first hydraulic cylinder 213 is positioned downwards and fixedly connected to the first pressure plate 214. Specifically, before clamping, the piston end of the first hydraulic cylinder 213 retracts, facilitating the placement of the workpiece at the bottom of the first pressure plate 214. When the first clamping assembly 21 moves to the workpiece to clamp it, the piston end of the first hydraulic cylinder 213 extends, causing the first pressure plate 214 to descend and clamp the top of the neat edge of the workpiece.

[0059] Preferred, such as Figure 6 As shown, it also includes a guide mechanism 4 disposed between the fixed pressing mechanism 2 and the movable pressing mechanism 3. The guide mechanism 4 includes a guide groove 41, a rotating shaft and a guide wheel 42. The guide groove 41 is disposed longitudinally on the top of the platform body 1 and its opening faces the movable pressing mechanism 3. Several rotating shafts are rotatably disposed in the guide groove 41. The guide wheel 42 is fixedly sleeved on the outside of the rotating shaft for contacting the neat edge of the workpiece to be welded and guiding the workpiece to be welded to move to the top of the platform body 1.

[0060] Working principle:

[0061] When pressing a plate-shaped structure with an irregular edge, the workpiece is guided to the top of the platform body 1 by the guide component 4. The irregular edge of the workpiece is placed towards the moving pressing mechanism 3. The first pressing component 21 on the fixed pressing mechanism 2 presses the top of the neat edge of the workpiece. Then, the moving component 31 is manually pushed, and the moving component 31 slides and moves in the slide groove 11 to a position close to the irregular edge of the workpiece. Then, the second pressing component 32 is rotated so that the second pressing component 32 presses the top of the workpiece. By setting multiple sets of moving components 31, it is convenient to adjust the moving position of the corresponding second pressing component 32 individually, so that it can better press the edge shape of the workpiece, improve the flexibility of the device adjustment, and increase the applicability of the device.
