[0030] like Figures 1 to 6 As shown in the figure, a contact water-cooled welding device in an embodiment of the present invention includes a control box 11 with a built-in control module, a first platform 12, a positioning tooling module, and a welding module. The first platform 12 is connected to a rotating disk 13.

[0031] The positioning tool module includes a contour welding base 22 for placing contacts, and a positioning component located between the rotating disk 13 and the contour welding base 22 for adjusting the position of the contour welding base 22.

[0032] The control box 11 is located on one side of the first platform 12. The welding module includes an induction coil 31, a ceramic rod 32, a connecting arm 33, and an infrared thermometer 35. The connecting arm 33 is fixed to the control box 11 and is arranged toward the rotating disk 13. A vertical hydraulic rod 34 is installed on the connecting arm 33. The ceramic rod 32 is vertically arranged and fixed to the bottom of the hydraulic rod 34. The infrared thermometer 35 is connected to the control box 11 near the induction coil 31, is electrically connected to the control module, and measures its temperature.

[0033] The control box 11 is further connected to a water cooling nozzle 41 , and the water outlet of the water cooling nozzle 41 is arranged toward the contoured welding base 22 .

[0034] This setting allows the equipment to control the diffusion of heat generated during induction welding by water-cooling a portion of the contact product during induction welding. This allows the heat generated by welding to be controlled at the edge of the contact point, preventing degradation of physical properties such as hardness. This improves production efficiency, reduces production costs, and enhances welding quality.

[0035] In this embodiment, the control module is specifically controlled by a PLC unit. The control box is equipped with operation buttons for each module, facilitating intelligent control.

The upper end of the lifting screw 242 passes through the fixed horizontal block 2412 and is connected to the third rotating operating member 245.

[0039] With this arrangement, the third rotating operating member can be rotated forward or reverse to drive the lifting seat, which is threadedly connected to the lifting screw, to rise and fall along the vertical guide rod, thereby adjusting the height position of the contact assembly for easy adjustment. In this embodiment, two vertical guide rods are provided and located on both sides of the lifting screw to further improve the stability of the lifting.

The second limiting rail 2212 is provided with a second rail groove 2213 that is adapted to the shape of the second sliding block 222 and extends along the Y-axis direction. The second sliding block 222 slides in the second rail groove 2213. The second adjusting screw 223 passes through the second sliding block 222 and forms a threaded connection with it. The rotation of the second adjusting screw 223 is fixed between the two second fixed support plates 2211. One end of the second adjusting screw 223 passes through the second fixed support plate 2211 and is connected to the second rotating operating member 224.

[0041] The first position adjustment assembly includes a first adjustment bracket 211, a first sliding block 212, and a first adjusting screw 213. The first adjustment bracket 211 is fixed to the second sliding block 222 and includes two parallel first fixed support plates 2111 and a first limiting rail 2112 connected between the first fixed support plates 2111. The first limiting rail 2112 is provided with a first rail slide groove 2113 that is adapted to the shape of the first sliding block 212 and extends along the X-axis direction. The first sliding block 212 slides in the first rail slide groove 2113. The first adjusting screw 213 passes through the first sliding block 212 and forms a threaded connection with it. The rotation of the first adjusting screw 213 is fixed between the two first fixed support plates 2111, and one end of the first adjusting screw 213 passes through the first fixed support plate 2111 and is connected to the first rotating operating member 214. The contoured welding base 22 is connected to the first sliding block 212.

[0042] This arrangement allows for rapid adjustment of the horizontal direction of the contoured welding base. In this embodiment, the first position adjustment assembly and the second position adjustment assembly have the same structure, which can further reduce production costs and improve processing convenience.

[0043] Two positioning tool modules are provided symmetrically with respect to the center of the rotating disk 13 .

[0044] With this setting, when the positioning tooling module on one side is performing welding operations, the positioning tooling on the other side can be used for loading, thereby improving production efficiency.

[0045] The bottom of the first platform 12 is connected to a rotation drive mechanism 14 , the output end of which is connected to the center line of the rotating disk 13 .

[0046] Through this arrangement, the accuracy is further improved, and the rotary drive mechanism is specifically a rotary motor combined with a reducer.

[0047] The edge of the rotating disk 13 has a flange 131 extending upward and forming a water storage tank 132.

[0048] With this arrangement, the water reservoir can prevent the cooling water from flowing randomly during the welding process.

[0049] A radially penetrating drain port 133 is provided at one position of the flange 131 .

[0050] The drain outlet can be connected to an external wastewater pipe, and the wastewater generated during the welding process of the contact assembly can be discharged through the drain outlet to avoid wastewater accumulation.

[0051] The water cooling nozzle 41 is a universal nozzle.

[0052] With this setting, the nozzle adopts a universal bamboo joint design, which can be used flexibly and can be used for product structures of different shapes.

[0053] The working principle of this embodiment is as follows:

[0054] (1) Positioning tooling module movement, first manually place the contact product on the contoured welding base, then use the positioning pin to fix the product, and then adjust the front and back, left and right, and height positions of the contact according to the position of the existing contact assembly. After the adjustment is completed, the welding tooling is locked by adjusting the fixing bolt to prevent the product from loosening due to the influence of the magnetic field force during the welding process, thereby affecting the size and position accuracy of the product.

[0055] (2) The welding module moves, and the connecting arm is used to fix the clamping mechanism. A ceramic rod of appropriate size is selected and installed in the clamping mechanism. The hydraulic rod is driven by the adjusting bolt to lock the ceramic rod to prevent the upper electrode ceramic rod from loosening during welding, which may cause the product to have poor dimensional quality. The position of the induction coil and the cooling water nozzle are then adjusted through the PLC system to prevent the product from being heated by the magnetic field of the induction coil and causing the physical properties of the product to deteriorate. The infrared thermometer is then adjusted to align the infrared rays with the appropriate contact position, and the welding operation can begin.

[0056] (3) The rotating module moves, the contact assembly is placed on the welding station, and after adjusting the corresponding position of the contact assembly, press the rotation button. After receiving the command, the rotating module drives the welding module to rotate 180 degrees, and rotates the contact assembly to be welded to the corresponding position of the welding module. Then press the welding start button, the welding module automatically raises and lowers the induction coil to the appropriate position, and the welding power supply starts welding. When the temperature reaches the set temperature during the welding process, an infrared thermometer detects the set temperature and feeds back to the host. The host stops heating and the product is welded.

[0057] (4) Repeat the above steps (1) to (3) to complete the welding of the contact assembly.

[0058] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
