Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, and in particular to a laser welding fixture for the water chamber of a water-cooled radiator. Background Technology

[0002] Water-cooled radiators are commonly used in water-cooled structures in production operations. The water chamber and heat dissipation module of the water-cooled radiator need to be welded together. Usually, wire is used to tie them together or heavy objects are used to press them together for alignment. The wire tying operation will block the weld seam and affect the one-time continuous welding of the water chamber of the water-cooled radiator. In addition, the tying process is time-consuming, and the wire used for tying is for one-time use, which wastes resources to a certain extent.

[0003] The technical problem to be solved by this invention is to design a laser welding fixture for water chambers of water-cooled radiators, to securely clamp water chambers of water-cooled radiators, to ensure that the welding gap is reduced during welding, to eliminate large areas of obstruction of the weld seam, to ensure that the welding of water chambers of water-cooled radiators can be completed directly in a single welding operation, and to reduce the waste of resources during repeated clamping or clamping of water chambers of water-cooled radiators of multiple sizes. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing a laser welding fixture for the water chamber of a water-cooled radiator.

[0005] To address the aforementioned problems, a laser welding fixture for the water chamber of a water-cooled radiator is provided. The fixture comprises a water-cooled radiator, a base plate, tension bolts, guide rods, support bolts, pressure rods, and locking rods. Multiple sets of locking rods are arranged side-by-side above the base plate. Pressure blocks are integrally cast laterally at both ends of each locking rod. A hole is vertically arranged in the center of each pressure block. An adjustment block is located at the center of each locking rod, and a hole is horizontally arranged in the center of each adjustment block. Multiple sets of guide blocks are arranged between the adjustment blocks and the multiple sets of pressure blocks. The guide blocks and adjustment blocks are arranged in the same direction, and guide holes are provided within each guide block. Multiple sets of pressure rods are arranged on the lower surface of the locking rods. Rubber is fixedly connected to the bottom of each pressure rod. Multiple sets of limiting pads are bolted to the top of the base plate. Each limiting pad includes a limiting block and a pad plate, and limiting blocks are welded around the pad plate.

[0006] Preferably, the lower surface of the base plate is provided with multiple sets of strip-shaped countersunk grooves.

[0007] Preferably, the water-cooled radiator includes a welding block A, a welding block B, and a heat sink, wherein a cavity and a limiting plate are provided between the welding block A and the welding block B, and the heat sink is disposed in the cavity and limited by the limiting plate.

[0008] Preferably, the welding block A is in contact with the upper surface of the limiting pad, and the limiting blocks provided on the multiple sets of limiting pads can restrict the four corners of the welding block A.

[0009] Preferably, the heat sink is installed inside the cavity of welding block A, and welding block B is disposed on top of welding block A in the same state.

[0010] Preferably, the locking rods are arranged side by side on the top of the welding block B and the rubber abuts against the upper surface of the welding block B. The guide rod passes through the guide block and one end is fixed in the hole of the guide block. The support bolt passes through the adjusting block and the adjusting block is provided with support nuts on both sides for adjusting the spacing of multiple sets of locking rods.

[0011] Preferably, multiple sets of tensioning bolts are provided in the multiple sets of countersunk grooves. The tail of the tensioning bolt passes through the hole provided on the lower pressure block, and there is a tensioning nut on the top of the lower pressure block. Tightening the tensioning nut can press the lower pressure block downward. After the lower pressure block is pressed downward, the rubber at the bottom of the lower pressure rod can press the welding block B.

[0012] In summary, the beneficial effects of this utility model are: This invention modifies some of the structure. During use, the limiting pad is bolted to the top of the base plate according to the size of welding block A. Welding block A, welding block B, and the heat sink are then placed on top of the limiting pad in the original installation order. Multiple sets of tension bolts are then inserted into the countersunk grooves, with lower pressure blocks connected to the bolt ends. Support bolts are used to adjust the spacing of the locking rods, ensuring that the rubber can press the welding block B as a whole. Finally, the tension nut is tightened to completely press the bottom rubber of the lower pressure rod against the welding block B. This ensures that welding block B is completely pressed against the top of welding block A. Furthermore, this invention uses multiple sets of bolt guide rods, allowing for adjustment of some dimensions. This ensures that a single welding operation can directly complete the welding of the water chamber of the water-cooled radiator, reducing resource waste during repeated clamping or clamping of water chambers of multiple sizes.

Multiple sets of limiting pads 220 are bolted to the top of the base plate 2. The limiting pads 220 include limiting blocks 221 and pads 222. Limiting blocks 221 are welded around the pads 222.

[0019] Furthermore, the lower surface of the base plate 2 is provided with multiple sets of strip-shaped countersunk grooves 211.

[0020] Please see Figure 2 As shown, the water-cooled radiator includes welding block A3, welding block B4 and heat sink 5. A cavity and a limiting plate are provided between welding block A3 and welding block B4. The heat sink 5 is disposed in the cavity and is limited by the limiting plate.

[0022] Furthermore, the heat sink 5 is installed inside the cavity of the welding block A3, and the welding block B4 is positioned on top of the welding block A3 in the same manner.

[0023] Furthermore, the locking rods 1 are arranged side by side on the top of the welding block B4 and the rubber abuts against the upper surface of the welding block B4.
