Description

[0002] In the rapid development of laser plastic welding technology, precise control of welding pressure is essential to ensure welding quality and improve yield. Traditional laser plastic welding equipment mostly relies on a single cylinder as the power source of the clamping platform to apply the necessary clamping force to maintain the workpiece stability and promote good welding results. However, this configuration has shown its limitations when faced with diverse material properties and complex welding requirements, especially in the scientific research and product development stages, where experimental conditions often need to simulate various welding pressure environments from gentle to high intensity.

[0003] Specifically, low pressures such as 100 Newtons may be suitable for precision welding of thin-walled or fragile materials to avoid material deformation or damage, while high pressures up to 500 Newtons are suitable for thick materials or applications that require high-strength welded joints. Traditional single-cylinder systems are difficult to switch flexibly within the pressure range and cannot be used in different pressure scenarios, which limits the breadth and accuracy of experiments, increases the cost and complexity of equipment replacement or modification, and is not flexible enough to use.

[0038] A dual-pressure switching welding clamping experimental platform according to an embodiment of the present application is described below with reference to the accompanying drawings.

The fixing frame 110 includes a clamping top plate 111 for lifting and clamping with the first lifting part 400 and a movable plate 112 installed at the lower end of the clamping top plate 111 for clamping and fixing. The movable plate 112 is movably installed at the lower end of the clamping top plate 111 by bolts. A welding port 113 is opened in the middle of the movable plate 112 for use by a laser head for power welding.

[0041] The clamping unit 200 includes a first lifting part 400 for lifting and clamping and a second lifting part 500 installed on the upper end of the first lifting part 400 for clamping. The first lifting part 400 and the second lifting part 500 are movably installed on the upper end of the operating platform 100, and cooperate with the fixing frame 110 fixedly installed on the upper end of the operating platform 100 to clamp the laser plastic welded parts.

[0042] The first lifting part 400 includes a first cylinder 410 for pushing the upper end bracket to move and a lifting frame 430 installed on the upper end of the first cylinder 410 for clamping and fixing. The lower end of the lifting frame 430 is connected to the telescopic output end of the first cylinder 410. The lifting frame 430 is limited by a limiting rod 450 installed at the lower end. A connecting frame 420 for supporting and fixing the first cylinder 410 is fixedly installed on the upper end of the first cylinder 410. The upper end of the connecting frame 420 is fixedly installed on the lower end of the operating platform 100.

[0043] The second lifting part 500 includes a second cylinder 510 for lifting and clamping and a second clamping plate 520 installed on the upper end of the second cylinder 510 for clamping laser plastic welding. The lower end of the second clamping plate 520 is connected to the output end of the upper end of the second cylinder 510.

[0044] In a low-pressure welding scenario, the second cylinder 510 of the second lifting part 500 is started, the second clamping plate 520 rises, and the first lifting part 400 does not work. In a high-pressure welding scenario, the telescopic part of the first cylinder 410 of the first lifting part 400 is started, the lifting frame 430 rises, and the second lifting part 500 rises accordingly, but the second cylinder 510 is not started. It can be suitable for different pressure scenarios and can provide different welding clamping forces.

[0045] A positioning frame 440 for supporting the second lifting part 500 at the upper end is embedded in the interior of the lifting frame 430. The second lifting part 500 is movably arranged at the upper end of the positioning frame 440. The positioning frame 440 is arranged in the middle of the lifting frame 430 and is connected to the operating platform 100 at the lower end. The positioning frame 440 is composed of two groups of symmetrically installed mounting parts 441. Both sides of the mounting parts 441 are fixedly installed with mounting seats 442 for positioning the mounting parts 441. The mounting seats 442 and the operating platform 100 are fastened by fastening bolts 444 movably installed at the lower end. When the second lifting part 500 at the upper end is installed, the positioning frame 440 at the lower end supports the second lifting part 500 at the upper end so that it is fixed to the upper end of the mounting parts 441.

[0046] Both sides of the mounting member 441 are provided with mounting holes 443 for fixing the mounting member 441 , and an electromagnetic telescopic rod 460 for fixing the mounting member 441 is movably installed inside the lifting frame 430 , and the electromagnetic telescopic rod 460 matches the position and size of the mounting hole 443 .

[0047] A storage rack 431 for placing the positioning rack 440 at the upper end is fixedly installed at the lower end of the lifting rack 430 , and a connector 432 for installation with the first cylinder 410 is installed at the lower end of the storage rack 431 .

[0048] When it is necessary to weld and fix a small area of ​​the welded parts, the fastening bolts 444 can be loosened to separate the mounting part 441 at the lower end from the operating platform 100, and then the electromagnetic telescopic rod 460 is extended and inserted into the inside of the mounting hole 443, thereby connecting the lifting frame 430 and the positioning frame 440 into a whole, and then the telescopic part of the first cylinder 410 of the first lifting part 400 at the lower end is started, and when the lifting frame 430 rises, it drives the second clamping plate 520 to rise for lifting and clamping, which is convenient for large-area objects. During welding, the fastening bolt 444 is tightened, and the electromagnetic telescopic rod 460 retracts to separate the lifting frame 430 and the positioning frame 440. When the lifting frame 430 rises, the storage frame 431 passes through the positioning frame 440 and moves upward, and then the movable frame 120 installed on the upper end moves upward with the lifting frame 430, and the second lifting part 500 sinks into the storage frame 431, and the part to be clamped can be clamped and fixed by the movable frame 120 and the fixed frame 110, so as to facilitate welding by the laser head inside the welding port 113.

[0049] A through slot 310 is formed in the middle of the lifting plate 300 for the lifting plate 300 to move. The clamping unit 200 is installed in the through slot 310 , and the lifting frame 430 is connected and fixed to the lifting plate 300 .

[0050] The lifting plate 300 is movably mounted on the upper end of the mobile frame 120 which is fixedly mounted on the upper end of the operating platform 100; a limit member 320 for limiting the lifting plate 300 is fixedly mounted on the lower end of the lifting plate 300; a roller 121 for facilitating the movement of the lifting plate 300 is movably mounted on the upper end of the mobile frame 120; the roller 121 is movably mounted inside a groove opened on the surface of the mobile frame 120 through a bearing, and is installed in contact with the lower surface of the lifting plate 300.

[0051] When the lifting plate 300 needs to be used, the lifting plate 300 can be moved and adjusted within the range of the through groove 310. The lifting plate 300 can be moved within a small range, which is easy to use and can be adjusted according to welding conditions and parts. The roller 121 can facilitate the movement of the lifting plate 300 to avoid jamming.

[0052] Specifically, the working principle of the dual-pressure switching welding clamping experimental platform is as follows: in a low-pressure welding scenario, the second cylinder 510 of the second lifting part 500 is started, the second clamping plate 520 rises, and the first lifting part 400 does not work; in a high-pressure welding scenario, the telescopic part of the first cylinder 410 of the first lifting part 400 is started, the lifting frame 430 rises, and the second lifting part 500 rises accordingly, but the second cylinder 510 is not started. It can be applied to different pressure scenarios and can provide different welding clamping forces. When it is necessary to weld and fix a small area of ​​a welded part, the fastening bolt 444 can be loosened to separate the mounting part 441 at the lower end from the operating platform 100, and then the electromagnetic telescopic rod 460 is extended and inserted into the inside of the mounting hole 443, and then The lifting frame 430 and the positioning frame 440 are connected into a whole, and then the telescopic part of the first cylinder 410 of the first lifting part 400 at the lower end is started. When the lifting frame 430 rises, it drives the second clamping plate 520 to rise for lifting and clamping. When welding large-area objects, tighten the fastening bolts 444, and the electromagnetic telescopic rod 460 retracts to separate the lifting frame 430 and the positioning frame 440. When the lifting frame 430 rises, the storage frame 431 passes through the positioning frame 440 and moves upward, and then the mobile frame 120 installed at the upper end moves upward with the lifting frame 430, and the second lifting part 500 sinks into the storage frame 431, and the part to be clamped can be clamped and fixed with the fixed frame 110 through the mobile frame 120, so that the laser head inside the welding port 113 can be welded.

[0053] It should be noted that the specific models and specifications of the first cylinder 410, the second cylinder 510, and the electromagnetic telescopic rod 460 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0054] The energy supply and principles of the first air cylinder 410 , the second air cylinder 510 , and the electromagnetic telescopic rod 460 are clear to those skilled in the art and will not be described in detail herein.
