[0001] The invention belongs to the technical field of transformer heat sinks, and in particular relates to a welding device for transformer heat sinks and a use method thereof. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It plays a vital role in domestic electricity use. The heat sink of the transformer is an important component for transformer heat dissipation. The transformer has very high requirements for heat dissipation. The transformer heat sink can reduce the thermal resistance of the transistor. Under the same ambient temperature, the power amplifier transistor can withstand greater dissipation power, thereby ensuring that the transformer can be used normally. The existing transformer heat sink is usually flat and vertically welded on the outer surface of the transformer to improve the heat dissipation effect.

[0003] When welding the heat sink to the outer surface of the transformer, during the welding process, the melted solutions of the two workpieces are mixed together, and then cooled and fixed to complete the welding process. However, during the welding process, the top workpiece will tilt after the welding starts, which affects the welding effect. Summary of the invention

[0006] Each of the left and right screw rods is meshed and connected with two connecting plates, and a sliding plate is arranged on the top of the four connecting plates.

[0007] As a preferred embodiment of the present invention, the two connecting plates on each of the above-mentioned left-hand and right-hand screw rods are respectively located on the left-hand thread and the right-hand thread of the left-hand and right-hand screw rods, and the two connecting plates are symmetrical about the center of the left-hand and right-hand screw rods.

[0009] As a preferred embodiment of the present invention, the rotating shafts of the two left and right screw rods pass through the second clamping plate and are coaxially mounted with a first gear.

[0010] As a preferred embodiment of the present invention, a second gear is installed on one side of the two second clamping plates on which the first gear is installed, and the two second gears are respectively meshed and connected to the first gear on that side.

[0011] As a preferred embodiment of the present invention, a rotating handle for controlling the rotation of the two second gears is installed at the center position of the two second gears, and a knob for limiting the rotation of the two second gears is installed on one side surface of the two second gears.

[0014] As a preferred embodiment of the present invention, a connecting base plate is installed at the bottom of the two telescopic rods, a sleeve block is installed at the bottom of the two connecting base plates, and a stop block is slidably connected to the two sleeve blocks.

[0015] A welding device for a transformer heat sink as claimed in any one of the preceding claims and a method of using the same, comprising the following steps:

[0016] Place the transformer body on top of the operating table and place a heat sink on top of the transformer body;

[0017] Pull the moving rod according to the position to be welded, and drive the four connecting blocks and the sliding plate to move to the position to be welded;

[0018] When clamping is required, rotate the two left and right screw rods to clamp the heat sink from both sides respectively, so that the heat sink is perpendicular to the transformer body;

After clamping, the knobs on the two second gears are tightened to fix the position of the heat sink, reduce the possibility of the heat sink being deflected during the welding process, and can improve the welding effect to a certain extent.

[0022] Before welding, the two blocks are moved to the top of the heat sink so that the two sleeve blocks are respectively against one side of the top of the heat sink. The welding process causes the two workpieces to melt and mix together, causing the other side to warp up. At this time, the heat sink will not warp up under the action of the two blocks, which improves the stability of the heat sink position during welding to a certain extent, further improving the welding effect.

[0039] Each left and right screw rod 211 is meshed and connected with two connecting plates 221. The connecting plates 221 of different heights can be selected according to the size of the transformer body. The two connecting plates 221 on each left and right screw rod 211 are respectively located on the left-handed thread and the right-handed thread of the left and right screw rod 211, and the two connecting plates 221 are symmetrical about the center of the left and right screw rods 211. When the two left and right screw rods 211 are rotated, the two connecting plates 221 on each left and right screw rod 211 move in a direction of approaching or moving away from each other. The tops of the four connecting plates 221 are provided with A sliding plate 223 is provided, and a connecting block 222 is installed on the top of each of the four connecting plates 221. The four sliding plates 223 are respectively slidably installed on one of the connecting blocks 222, and each sliding plate 223 can slide on one of the connecting blocks 222, and a limiting pull rod 224 is slidably inserted between the two sliding plates 223 located on the top of the same sliding block 201.

[0040] In order to reduce the possibility of one end of the heat sink lifting during welding, Figure 1-Figure 2 and Figure 6 As shown, a support plate 301 is installed on the top of the first card plate 202 and the second card plate 203 on each sliding block 201, a top plate 302 is installed on the top of the two support plates 301 on each sliding block 201, a telescopic rod 303 is installed on the bottom of the two top plates 302, a connecting base plate 304 is installed on the bottom of the two telescopic rods 303, a sleeve block 305 is installed on the bottom of the two connecting base plates 304, and the two sleeve blocks 305 are slidably connected with a stopper 306, and the height of the two stoppers 306 from the top of the heat sink is controlled by the two telescopic rods 303.

[0041] When using the welding device for transformer heat sink, place the transformer body to be welded on the top of the operating table 101, and take the heat sink and place it on the top of the transformer body. According to the position where the heat sink needs to be welded, control the moving pull rod 113 to drive the two sliding blocks 201 to move, control the two limit pull rods 224 to drive the four sliding plates 223 on both sides to slide to the appropriate position, and after sliding, rotate the two rotating handles 214 on both sides to control the two connecting plates 221 on each side to move in a direction close to each other, and when the connecting plate 221 moves, it drives the connecting block 222 and the sliding plate 223 to move, so that The two sliding plates 223 on each side are clamped on the heat sink, and the knobs 215 on the two second gears 213 are tightened after clamping. When the heat sink is welded to the outside of the transformer body, the two blocks 306 are moved to the top of the heat sink before welding, and the two telescopic rods 303 are opened to drive the two blocks 306 to move downward, so that the two sleeve blocks 305 are respectively against one side of the top of the heat sink. The welding process causes the two workpieces to melt and mix together. The bottom of the heat sink on this side lacks support, and the height will change after cooling and fixing, causing the other side to tilt up. At this time, the heat sink will not tilt up under the action of the two blocks 306.
