[0002] The processing of auto parts lays the foundation for the subsequent production and manufacturing of the entire vehicle. Each auto part directly affects the performance and safety of the entire vehicle. Auto parts include intake valves, engines, cylinder blocks, and automobile ignition coils, etc. When processing automobile ignition coils, a welding table is required; When welding the automobile ignition coil, the stability of the electrical connection of the automobile ignition coil can be improved. The welding process provides a reliable electrical path, and the welding process also improves the durability and reliability of the automobile ignition coil, thereby extending the service life of the automobile ignition coil; When the welding table is working, the automobile ignition coil needs to be clamped quickly. Due to the difference in car models, the size of the automobile ignition coil will also be different. At the same time, due to the difference in engine type and performance, the size of the automobile ignition coil will also be different. Therefore, the welding table needs to quickly adapt to automobile ignition coils of different sizes, otherwise it will affect the processing efficiency. In order to overcome the above defects, prior art 1 (Chinese patent with application number CN202023141127.5 and application date 2020-12-22) is a welding table for automobile ignition coils. It uses a connecting plate and a screw rod in conjunction with a driving structure to fix the welding table when welding the automobile ignition coil. The staff only needs to place the ignition coil directly on the placement table, so that the two longer sides of the automobile ignition coil can be clamped and fixed by the relative fixing blocks. There is no need to deliberately adjust the placement position of the ignition coil to clamp it, thereby simplifying the use steps of the welding table and improving the overall work efficiency of the welding process. Prior art 2 (application number CN202220171991.X, application date 2022-01-22) is a Chinese patent, a welding table for automobile ignition coils, which can place the ignition coil in the clamping plates and release it after pulling outwards through two sets of clamping plates. At this time, the clamping plates can be pushed to clamp the ignition coil by the rebound of the spring. The clamping operation is simple and convenient, stable and reliable, and greatly improves the welding efficiency. The exhaust fan can be started during welding. At this time, the smoke generated by welding can be drawn in through the smoke inlet and finally discharged through the hose, and the hose can be connected to the outdoors, thereby avoiding damage to the human body caused by welding smoke in the factory, improving the production environment, and improving the protection of workers; There is also prior art 3 (Chinese patent with application number CN202420243509.8 and application date 2024-01-31) an automobile ignition coil welding table, which places the ignition coil between the first rotating plate and the second rotating plate, rotates the hand wheel to drive the screw to rotate, the screw drives the first slider and the second slider thereon to move relative to each other synchronously, the first slider and the second slider drive the first clamping plate and the second clamping plate to move relative to each other synchronously, the first clamping plate and the second clamping plate drive the first rotating plate and the second rotating plate to move relative to each other synchronously, until the first rotating plate and the second rotating plate clamp the ignition coil welding part, so that the ignition coil is clamped and fixed between the first rotating plate and the second rotating plate, which is beneficial to improve the clamping efficiency; During the welding process of the workpiece, harmful gases will be generated. The fumes generated during the welding process contain particulate matter, which will affect the operator's respiratory tract and lungs. They also contain carcinogens. Long-term inhalation of these particles may increase the risk of cancer. During use, the device in the above application uses a single fan to exhaust gas, and its working efficiency is general.

The specific contents are as follows: (1) The welding table for automobile ignition coils provided with a limiting structure needs to start the motor when the automobile ignition coil needs to be clamped during operation.

The side plates 9 are symmetrically distributed about the center of the threaded rod 5, and the threads on the left and right sides of the threaded rod 5 have opposite rotation directions.

[0020] During work, when it is necessary to clamp the automobile ignition coil, the motor 4 needs to be started. At this time, the side plate 9 moves to the middle position of the bottom plate 1 under the action of the threaded rod 5 and the limit rod 10, and then the working plates 6 and the clamping plates 7 on the left and right sides approach each other, and finally the clamping plate 7 clamps and fixes the workpiece. The operation process is quick and convenient, and the work efficiency is high. After the workpiece is clamped and fixed, the welding head is controlled by the robot arm 3 to achieve welding of the workpiece, which is easy to operate.

[0021] Embodiment 2: Different from Embodiment 1, the harmful gas generated during welding can be quickly collected and discharged by setting the gas exhaust component, thus optimizing the working environment. Figure 4-Figure 6 As shown: The gas exhaust assembly also includes a first bevel gear 13 fixedly connected to the upper surface of the connecting shaft 12 , a traction rope 21 is fixedly connected to the inner wall of the enclosure 2 , and the other side of the traction rope 21 is wound and fixedly connected to the surface of the connecting shaft 12 .

[0024] When welding is in progress, the suction head 19 can absorb the fume generated during welding, optimize the working environment of the staff, and thus protect the health of the staff. After welding is completed, the motor 4 rotates, and the working plate 6 moves back. When the working plate 6 is driven to move by the side plate 9, the connecting shaft 12 rotates inside the external plate 11 under the action of the traction rope 21 and the torsion spring 33. At this time, the long pin 14 rotates under the action of the first bevel gear 13 and the second bevel gear 15. At this time, the long pin 14 drives the cam 16 to rotate synchronously. When the cam 16 rotates to push the force-bearing plate 17, the force-bearing plate 17 rises, and when the cam 16 continues to rotate to stop pushing the force-bearing plate 17, the force-bearing plate 17 descends under the action of its own gravity, and then the force-bearing plate 17 and the push rod 22 make reciprocating linear motion in the vertical direction under the action of the cam 16, their own gravity and the connecting rod 18. At this time, the pipe sleeve 24 and the adsorption head 19 swing around the auxiliary rod 23 under the action of the thrust of the push rod 22 and their own gravity. At this time, the working range of the adsorption head 19 is increased, which can better absorb the smoke.

[0025] Embodiment 3: Different from Embodiment 2, the auxiliary material discharge assembly is provided to enable the welding slag to be discharged quickly during the welding process, so that it is convenient for the staff to collect it. Figure 7-Figure 10 As shown: The auxiliary blanking assembly includes a circular plate 31 fixedly connected to the lower surface of the connecting shaft 12, and a fixing block 32 is fixedly connected to the lower surface of the circular plate 31, and the fixing block 32 is a hemispherical structure, and the fixing blocks 32 are evenly spaced on the lower surface of the circular plate 31.

[0026] The upper connecting block 27 is symmetrically distributed about the center of the receiving plate 8, and the upper surface of the receiving plate 8 is an arc-shaped structure. The upper surface of the bottom plate 1 is fixedly connected with a column 28, and the column 28 runs through the interior of the receiving plate 8, and the upper surface of the column 28 is fixedly connected with a baffle 30, the lower surface of the receiving plate 8 is fixedly connected with a connecting spring 29, and the other side of the connecting spring 29 is fixedly connected to the upper surface of the bottom plate 1, and a discharge port 26 is opened on the surface of the bottom plate 1, and the surface of the connecting shaft 12 is fixedly connected with a torsion spring 33 which plays an elastic reset role, and the other side of the torsion spring 33 is fixedly connected to the inner wall of the external connecting plate 11.

[0027] During welding, welding slag will fall onto the receiving plate 8, and the upper surface of the receiving plate 8 is an arc-shaped structure, so the receiving plate 8 can quickly discharge the welding slag, which is convenient for the welding slag to be discharged from the discharge port 26, and then it is convenient for the staff to quickly collect it. When the connecting shaft 12 rotates, the connecting shaft 12 drives the circular plate 31 and the fixed block 32 to rotate synchronously. When the fixed block 32 rotates to push the upper connecting block 27, the upper connecting block 27 and the receiving plate 8 descend under the thrust. At this time, the connecting spring 29 will be compressed, and when the fixed block 32 continues to rotate until it does not push the upper connecting block 27, the receiving plate 8 returns to its original position under the action of the connecting spring 29, and then the receiving plate 8 performs reciprocating linear motion in the vertical direction under the action of the thrust and elastic force as well as the column 28 and the baffle 30, that is, the receiving plate 8 is in a shaking state, which is convenient for rapid material discharge, makes it easier to discharge the welding slag, and improves work efficiency.

[0028] When the connecting shaft 12 rotates, the torsion spring 33 is stretched, and then the motor 4 rotates. When the working plate 6 and the external plate 11 move back, the connecting shaft 12 rotates under the action of the torsion spring 33. When the connecting shaft 12 rotates, the traction rope 21 is reeled in for the next use. At the same time, when the connecting shaft 12 rotates, the above process occurs again, thereby improving work efficiency.

[0029] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
