[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This utility model discloses a copper-aluminum resistance welding device for an electromagnetic valve, including a workpiece body 1, a rotating mechanism 2, a welding structure 3 and a positioning structure 4. The workpiece body 1 is located at the movable end of the rotating mechanism 2, the welding structure 3 is located outside the rotating mechanism 2, and the top end of the rotating mechanism 2 is fixedly connected to the bottom end of the positioning structure 4.

[0024] The rotating mechanism 2 includes a drive base 201, a rotating platform 202 is mounted on the movable end of the drive base 201, and a fixed disk 207 is rotatably connected above the rotating platform 202. The fixed disk 207 is stationary relative to the rotating platform 202.

[0025] The welding structure 3 includes a mounting base 301, on the outer side of which a first cylinder 302 is fixedly mounted. A transverse slide rail 303 is fixedly mounted on the top of the mounting base 301. A movable block 304 is fixedly connected to the movable end of the transverse slide rail 303. The outer side of the movable block 304 is fixedly connected to the movable end of the first cylinder 302. A welding needle 306 is movably engaged at the top of the movable block 304 via a clamping seat 305.

[0026] The positioning structure 4 includes a fixed base 401, the bottom end of which is installed on the top end of the fixed plate 207. A second cylinder 402 is installed on the top end of the fixed base 401. A vertical slide rail 403 is fixedly connected to the inner side of the fixed base 401. A push block 404 is fixedly connected to the movable end of the vertical slide rail 403. The top end of the push block 404 is fixedly connected to the movable end of the second cylinder 402. A clamping cylinder 405 is fixedly installed on the outer side of the push block 404. Two abutting blocks 406 are fixedly connected to the movable end of the clamping cylinder 405.

[0027] Specifically, a jig cylinder 203 is installed at the top of the rotary table 202, and the workpiece body 1 is located inside the jig cylinder 203.

[0028] In this embodiment, by setting the jig cylinder 203, the workpiece body 1 can be well supported, making the workpiece body 1 more stable during the welding process. At the same time, the inner wall of the jig cylinder 203 fits against the outer wall of the workpiece body 1, which can limit the workpiece body 1 and prevent it from shifting during the welding process, thus further improving the welding accuracy.

[0029] Specifically, a lifting rod 204 is fixedly installed on the outer side of the drive base 201. The top end of the lifting rod 204 is rotatably connected to an abutment wheel 206 through a bearing seat 205. The top end of the abutment wheel 206 overlaps with the bottom end of the rotary table 202.

[0030] In this embodiment, by setting up a lifting rod 204, a bearing seat 205, and a contact wheel 206, when the rotary table 202 rotates, the contact wheel 206 will roll at the bottom of the rotary table 202, which can provide good support for the rotary table 202. At the same time, the friction of the contact wheel 206 when rolling is small, which makes the rotary table 202 rotate more smoothly, further improving the practicality of the solenoid valve copper-aluminum resistance welding device.

[0031] Specifically, the clamping seat 305 includes a lower clamping plate and an upper clamping plate, which are movably engaged with each other, and the welding needle 306 is located between the lower clamping plate and the upper clamping plate.

[0032] In this embodiment, by setting up a lower clamping plate and an upper clamping plate, the welding needle 306 can be well clamped, preventing the welding needle 306 from falling off during use. At the same time, the lower clamping plate and the upper clamping plate are movable and interlocked, making it convenient for workers to replace the welding needle 306, further improving the convenience of the solenoid valve copper-aluminum resistance welding device.

[0033] Specifically, the two bonding blocks 406 move in opposite directions, and through holes are opened on the opposite surfaces of the two bonding blocks 406. The welding needle 306 overlaps with the workpiece body 1 through the through holes.

[0034] In this embodiment, by setting the two bonding blocks 406 to move in opposite directions, the two bonding blocks 406 can simultaneously clamp both sides of the workpiece body 1, improving clamping stability. Simultaneously, through-holes are opened on the opposite surfaces of both bonding blocks 406, allowing the welding needle 306 to smoothly pass through the through-holes and overlap with the workpiece body 1, thereby completing the welding operation. This design not only improves welding accuracy but also ensures safety during the welding process, avoiding welding quality problems caused by unstable clamping or deviation of the welding needle 306. Furthermore, this design makes the entire welding process smoother and improves welding efficiency.

[0035] When in use, the operator places the workpiece body 1 inside the fixture cylinder 203, then starts the drive base 201, causing the rotary table 202 to start rotating, and driving the fixture cylinder 203 and the workpiece body 1 inside it to rotate together.

[0036] When the workpiece body 1 is rotated to the bottom of the welding structure 3, the second cylinder 402 is activated. The second cylinder 402 drives the clamping cylinder 405 to move through the push block 404. The clamping cylinder 405 clamps and positions the workpiece body 1 through two contact blocks 406.

[0037] Then, the first cylinder 302 is activated, its piston rod extends, and pushes the moving block 304 to move along the transverse slide rail 303. The movement of the moving block 304 causes the clamping seat 305 at its top and the welding needle 306 to move together until the welding needle 306 is precisely positioned at the welding part of the workpiece body 1. At this time, the welding needle 306 generates high temperature under the action of external power supply, and performs resistance welding on the workpiece body 1.

[0038] After welding is completed, the piston rod of the first cylinder 302 retracts, causing the welding needle 306 to move away from the workpiece body 1;

[0039] Subsequently, the drive base 201 is restarted, and the rotary table 202 continues to rotate, rotating the completed welded workpiece body 1 to a position away from the welding structure 3. At the same time, the next workpiece body 1 to be welded is rotated to the bottom of the welding structure 3, ready for the next round of welding operations.

[0040] In summary, this solenoid valve copper-aluminum resistance welding device, by setting up a rotating mechanism 2 and a positioning structure 4, uses a drive base 201 to drive the jig cylinder 203 on the rotating table 202 to rotate in a specific direction. In conjunction with the second cylinder 402, the two contact blocks 406 at the moving end of the clamping cylinder 405 can be driven by the vertical slide rail 403 to position the workpiece body 1. This allows the workpiece body 1 to automatically move to the welding point of the welding structure 3 and move away after welding is completed. This achieves automated operation of the welding process, eliminating the need for manual clamping and disassembly of the workpiece, improving welding efficiency and reducing the labor intensity of the workers.

[0041] It should be noted that the specific models and specifications of the drive base 201, the first cylinder 302, the welding needle 306, the second cylinder 402, and the clamping cylinder 405 in the solenoid valve copper-aluminum resistance welding device need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] Furthermore, the power supply and operating principle of the drive base 201, the first cylinder 302, the welding needle 306, the second cylinder 402, and the clamping cylinder 405 in the solenoid valve copper-aluminum resistance welding device are clear to those skilled in the art and will not be described in detail here.

[0043] Furthermore, the working principles and wiring methods of the drive base 201, the first cylinder 302, the welding needle 306, the second cylinder 402, and the clamping cylinder 405 in the solenoid valve copper-aluminum resistance welding device are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
