Description

Technical Field

[0001] This utility model relates to the field of single-ended pen-type ignition coil core processing technology, specifically a single-ended pen-type ignition coil core welding device. Background Technology

[0002] The single-ended pencil ignition coil is a key component of an automotive engine ignition system. It combines the high-voltage ignition wire and the ignition coil into one, directly mounted on top of the spark plug. This eliminates the need for a high-voltage wire, providing the high voltage required for ignition of the air-fuel mixture in the engine cylinder. In the manufacturing of the single-ended pencil ignition coil, the iron core is the core component, and its welding quality directly affects the magnetic circuit stability and overall performance of the ignition coil. The iron core is typically made of multiple layers of laminated silicon steel sheets, requiring welding to fix the layers and connect it to the housing, end plates, and other structures to ensure magnetic circuit continuity and structural rigidity.

[0003] In the existing single-headed pen-type ignition coil core welding process, after the worker welds one side of the core, the core position needs to be manually changed so that the welding machine can weld the other side of the core. This is quite troublesome and affects work efficiency, so it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a single-headed pen-type ignition coil core welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-headed pen-type ignition coil core welding device, comprising a processing table, a rotating mechanism disposed on the inner side of the processing table, a clamping mechanism disposed on the inner side of the rotating mechanism, a support frame fixedly connected to the top of the processing table, a second hydraulic cylinder fixedly connected to the right side of the support frame, a slider fixedly connected to the left side of the second hydraulic cylinder, a first hydraulic cylinder fixedly connected to the top of the slider, a lifting frame fixedly connected to the bottom of the first hydraulic cylinder, a third hydraulic cylinder fixedly connected to the back end of the lifting frame, a welding machine fixedly connected to the front of the third hydraulic cylinder, and a core body disposed on the inner side of the clamping mechanism;

Through the circular groove, the support member can slide on the inner side of the processing table. The support member can support the rotating disk, making the rotating disk more stable during rotation.

[0008] Preferably, the inner side of the processing table is provided with a circular hole corresponding to the position of the linkage rod, and the linkage rod is rotatably connected to the inner side of the circular hole. Through the circular hole, the linkage rod can rotate inside the processing table.

[0009] Preferably, the iron core body is disposed inside the storage frame, and the bottom of the iron core body is in close contact with the top of the inner side of the storage frame. The storage frame can play a preliminary limiting role for the iron core body, making the iron core body more stable during the welding process.

[0010] Preferably, the clamping mechanism includes a bidirectional threaded rod, which is rotatably connected to the inner side of the storage frame. A rotating disk is fixedly connected to the outer side of the bidirectional threaded rod, and a threaded plate is threadedly connected to the periphery of the bidirectional threaded rod.

This improves the rotational accuracy of the rotating disk and the storage frame, effectively preventing the weld seam of the single-headed pen-type ignition coil core body from shifting due to shaking during the welding process. The rotational coordination between the support disk and the rotating disk enhances the load-bearing stability of the storage frame.

[0015] 2. In this single-headed pen-type ignition coil core welding device, the clamping mechanism drives the threaded plate to move symmetrically through a bidirectional threaded rod, thereby enabling the clamping plate to clamp the single-headed pen-type ignition coil core body in the center. This avoids the core tilting caused by traditional single-sided clamping, ensures the coaxiality of the welding point and the core axis, and improves the consistency of welding quality.

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-4 This utility model provides a technical solution: a single-headed pen-type ignition coil core welding device, including a processing table 1, a rotating mechanism 2 arranged inside the processing table 1, a clamping mechanism 3 arranged inside the rotating mechanism 2, a support frame 4 fixedly connected to the top of the processing table 1, a second hydraulic cylinder 7 fixedly connected to the right side of the support frame 4, a slider 6 fixedly connected to the left side of the second hydraulic cylinder 7, a first hydraulic cylinder 5 fixedly connected to the top of the slider 6, a lifting frame 91 fixedly connected to the bottom of the first hydraulic cylinder 5, a third hydraulic cylinder 9 fixedly connected to the back end of the lifting frame 91, a welding machine 92 fixedly connected to the front of the third hydraulic cylinder 9, and a core body 8 arranged inside the clamping mechanism 3;

[0027] The rotating mechanism 2 includes a protective frame 202, which is fixedly connected to the top of the inner side of the processing table 1. A first servo motor 21 is fixedly connected to the bottom of the protective frame 202. A rotating shaft 26 is fixedly connected to the top of the first servo motor 21. A drive gear 22 is fixedly connected to the outer periphery of the rotating shaft 26. A reduction gear 27 meshes with the back end of the drive gear 22. A linkage rod 28 is fixedly connected to the inner side of the reduction gear 27. A rotating disk 24 is fixedly connected to the top of the linkage rod 28. The bottom of the linkage rod 28 is rotatably connected to the inner side of the protective frame 202. A support member 23 is fixedly connected to the outer periphery of the bottom of the rotating disk 24. A second servo motor 29 is fixedly connected to the inner side of the rotating disk 24. A rotating rod 201 is fixedly connected to the top of the second servo motor 29. A storage frame 25 is fixedly connected to the top of the rotating rod 201. A support plate 203 is fixedly connected to the outer periphery of the bottom of the storage frame 25. The support plate 203 is rotatably connected to the inner side of the rotating disk 24.

[0028] Furthermore, a circular groove corresponding to the movement trajectory of the support member 23 is provided on the inner side of the processing table 1, and the support member 23 is slidably connected inside the circular groove. Through the circular groove, the support member 23 can slide on the inner side of the processing table 1. The support member 23 can support the rotating disk 24, making the rotating disk 24 more stable during rotation.

[0029] Furthermore, a circular hole corresponding to the position of the linkage rod 28 is provided on the inner side of the processing table 1, and the linkage rod 28 is rotatably connected to the inner side of the circular hole. Through the circular hole, the linkage rod 28 can rotate inside the processing table 1.

[0030] Furthermore, the iron core body 8 is disposed inside the storage frame 25, and the bottom of the iron core body 8 is in contact with the top of the inner side of the storage frame 25. The storage frame 25 can play a preliminary limiting role for the iron core body 8, making the iron core body 8 more stable during the welding process.

[0031] Example 2

[0032] Please see Figure 1-4 Furthermore, based on Embodiment 1, the clamping mechanism 3 includes a bidirectional threaded rod 32, which is rotatably connected to the inner side of the storage frame 25. A rotating disk 31 is fixedly connected to the outer side of the bidirectional threaded rod 32, and a threaded plate 33 is threadedly connected to the outer periphery of the bidirectional threaded rod 32. A clamping plate 34 is fixedly connected to the top of the threaded plate 33.

[0033] Furthermore, a groove corresponding to the movement trajectory of the threaded plate 33 is provided on the inner side of the storage frame 25, and the threaded plate 33 is slidably connected to the inside of the groove. Through the groove, the threaded plate 33 can slide inside the storage frame 25, making the threaded plate 33 more stable during movement.

[0034] Furthermore, a moving groove corresponding to the movement trajectory of the slider 6 is opened on the inner side of the support frame 4, and the slider 6 is slidably connected inside the moving groove. Through the opening of the moving groove, the slider 6 can slide on the inner side of the support frame 4, so that the slider 6 can drive the lifting frame 91 and the third hydraulic cylinder 9 to move.

[0035] In actual operation, when this device is used, the single-ended pen-type ignition coil core body 8 is placed inside the storage frame 25, and its bottom is attached to the inner wall of the storage frame 25 to achieve initial positioning. Multiple single-ended pen-type ignition coil core bodies 8 are stacked together. The rotating disk 31 drives the bidirectional threaded rod 32 to rotate. Since the threaded plate 33 is threadedly connected to the bidirectional threaded rod 32 and is limited by the inner groove of the storage frame 25, the threaded plate 33 will move symmetrically along the groove, thereby driving the clamping plate 34 to move closer to the core body 8 at the same time, until the clamping plates 34 on both sides are tightly attached to the outer circle of the core body 8, completing the centering clamping of the single-ended pen-type ignition coil core body 8, ensuring that the core body 8 does not shift during the welding process.

[0036] Open the second hydraulic cylinder 7, causing it to push the slider 6 and the first hydraulic cylinder 5 to move. The slider 6 then moves the first hydraulic cylinder 5 to the top center of the rotating disk 24. Open the first hydraulic cylinder 5, causing it to move the lifting frame 91 and the third hydraulic cylinder 9 downwards. The lifting frame 91 then moves the welding machine 92 downwards to the back end of the iron core body 8. Open the third hydraulic cylinder 9, causing it to push the welding machine 92 to move, so that the welding machine 92 can contact the back end of the single-headed pen-type ignition coil iron core body 8 and weld the stacked single-headed pen-type ignition coil iron core bodies 8.

[0037] If it is necessary to adjust the position of the single-headed pen-type ignition coil core body 8, the second servo motor 29 is started, which drives the storage frame 25 to rotate through the rotating rod 201. The support plate 203 at the bottom of the storage frame 25 rotates synchronously along the inner side of the rotating plate 24 to ensure that the single-headed pen-type ignition coil core body 8 remains stable during rotation, so that the welding machine 92 can weld the left and right sides of the single-headed pen-type ignition coil core body 8.

[0038] After the single-headed pen-type ignition coil core body 8 on the front of the welding machine 92 is welded, the first servo motor 21 is started. The first servo motor 21 drives the drive gear 22 to rotate through the rotating shaft 26. The drive gear 22 meshes with the reduction gear 27 to transmit power to the linkage rod 28, causing the linkage rod 28 to drive the rotating disk 24 to rotate. The support member 23 at the bottom of the rotating disk 24 slides along the inner circular groove of the processing table 1 to provide stable support for the rotating disk 24, realizing the circular motion of the single-headed pen-type ignition coil core body 8 around the vertical axis, so that the right single-headed pen-type ignition coil core body 8 can move to the front of the welding machine 92, so that the welding machine 92 can weld the outer periphery of the remaining single-headed pen-type ignition coil core bodies 8.
