Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a laser welding clamping fixture for preventing deformation during the welding of thin plates. Background Technology

[0002] The core applications of thin-plate welding are concentrated in areas requiring lightweighting, high precision, and minimal deformation. Especially with the rapid development of industries such as new energy vehicles, consumer electronics, and medical devices, its application scope continues to expand. High-precision processes such as laser welding, electron beam welding, and micro-beam plasma welding have become the mainstream choices for thin-plate welding, and they hold immense potential for future miniaturization and intelligent manufacturing.

[0003] Thin sheet metal parts have poor rigidity and require clamps to be fixed to the worktable surface. In existing technologies, welding tables are generally flat, and when a thin sheet metal part is placed on the surface, it easily adheres to the table. Separating the sheet metal from the welding table requires external force to unload it after welding. Due to the thinness of the sheet metal, deformation is easily caused during unloading, affecting the quality of the welded part. Furthermore, existing clamps pose a risk of damaging the surface of the sheet metal when clamping it, necessitating improvement. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a laser welding clamping fixture for preventing deformation during the welding of thin sheet metal parts.

[0005] This utility model is achieved through the following technical solution:

[0006] A laser welding clamping fixture for preventing deformation during welding of thin sheet metal includes a base plate and an operating table. The operating table comprises a composite upper operating table surface and a lower operating table surface. A plurality of lifting rods are vertically connected between the base plate and the operating table surface. A hollow groove is formed through the center of the operating table surface. A plurality of arc-shaped protrusions are distributed parallel to each other on the upper surface of the upper operating table surface. A pressure block is provided above the upper operating table surface. The pressure block includes a pressure rod, a telescopic rod, a support rod, and a pressure ball. The telescopic rod is fixed below the pressure rod. The pressure rod is horizontally positioned at the top of the telescopic rod. A plurality of support rods are connected to the side of the pressure rod. A pressure ball is fixed at the lower end of the support rod and is located above the arc-shaped protrusions.

[0007] The arc-shaped protrusions are arranged parallel to the hollow groove, and the distance between adjacent arc-shaped protrusions is 0 cm.

[0008] The pressure ball is covered with a rubber block.

[0009] The upper layer of the work surface is a ceramic plate, and the lower layer of the work surface is a steel plate. The upper layer of the work surface and the lower layer of the work surface are bonded together with an adhesive.

[0010] The rubber block is a spherical hollow rubber block with an opening on one side.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The upper part of the worktable of this utility model is provided with multiple parallel arc-shaped protrusions, which can prevent the thin plate from adhering to the worktable, facilitate the movement of the thin plate, reduce the deformation risk during the welding and unloading process of the thin plate, and make the design more reasonable. The pressure ball used in the structure is covered with a rubber block, which can play a buffering and protective role during the clamping of the thin plate, so as to clamp the plate to the welding table without damaging the plate.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] As shown in the attached diagram of the instruction manual. Figures 1 to 3 As shown, a laser welding clamping fixture for preventing deformation during welding of thin plates includes a base plate 1 and an operating table. The operating table includes a composite-connected upper operating table 2 and a lower operating table 6. Several lifting rods 4 are vertically connected between the base plate 1 and the operating table. A hollow groove 3 is opened through the middle of the operating table. Several arc-shaped protrusions 21 are distributed parallel to each other on the upper surface of the upper operating table 2. A pressure block 5 is provided above the upper operating table 2. The pressure block 5 includes a pressure rod 5-2, a telescopic rod 5-1, a support rod 5-3, and a pressure ball 5-4. The telescopic rod 5-1 is fixed below the pressure rod 5-2. The pressure rod 5-2 is horizontally set at the top of the telescopic rod 5-1. Several support rods 5-3 are connected to the side of the pressure rod 5-2. The lower end of the support rod 5-3 is fixed with a pressure ball 5-4, which is located above the arc-shaped protrusions 21.

[0019] In this embodiment, the thin plate is placed on the workbench for welding. Welding is performed from the hollow groove 3. The upper layer of the new workbench has multiple parallel arc-shaped protrusions, which leaves a gap between the thin plate and the welding table, allowing air to circulate between them. This prevents the thin plate from adhering to the workbench, facilitates the movement of the thin plate, and reduces the risk of deformation during the welding and unloading process. The design is more reasonable.

[0020] The arc-shaped protrusions 21 are arranged parallel to the hollow grooves 3, and the distance between adjacent arc-shaped protrusions 21 is 0.5cm.

[0021] In this embodiment, the pressure ball 5-4 is externally covered with a rubber block 5-5. The rubber block covering the outer surface of the pressure ball used in the structure can provide cushioning and protection during the clamping process of the thin plate, which can clamp the plate to the welding station without damaging the plate and causing deformation.

[0022] Furthermore, in the structure, the upper layer 2 of the work surface is a ceramic plate, and the lower layer 6 is a steel plate. The upper layer 2 and the lower layer 6 are bonded together with an adhesive. Using a ceramic plate as the work surface has the characteristics of uniform heat conduction and durability.

[0023] Rubber block 5-5 is a spherical hollow rubber block with an opening on one side. The rubber block can be replaced after a period of use.
