Description

Technical Field

[0001] This utility model relates to the field of ignition coil processing technology, specifically a riveting machine for ignition coil processing. Background Technology

[0002] In the manufacturing process of ignition coils, the iron core, as the core component, is usually formed by stacking multiple silicon steel sheets and then riveting them together. The processing accuracy of the iron core directly affects the electromagnetic performance and overall working efficiency of the ignition coil. Therefore, the riveting quality of the silicon steel sheets is extremely important. Currently, existing riveting equipment used for processing ignition coil cores has many problems in practical applications: Traditional equipment has a simple design for fixing silicon steel sheets, often using single-sided clamping or manual positioning. This can easily lead to loosening, displacement, or skewing of multiple silicon steel sheets during the riveting process, resulting in poor stacking neatness and directly affecting the dimensional accuracy of the iron core and the subsequent assembly quality. Furthermore, most of the equipment is only set up with a single processing station, and can only rivet one set of silicon steel sheets at a time, which cannot meet the needs of mass production. The output per unit time is limited, which restricts the improvement of production efficiency.

[0003] Traditional equipment relies heavily on manual operation for adjusting riveting parameters, resulting in unstable precision control and an inability to achieve linkage control between fixing and riveting processes. This leads to poor processing consistency and large fluctuations in product qualification rate.

[0004] According to the description in the riveting machine for processing ignition coils published on the patent website (authorization announcement number: CN214133804U), the riveting machine for processing ignition coils includes a "base plate, concave frame", etc., to realize the riveting work.

[0005] Regarding the above description, the applicant believes the following issues exist: The riveting machine used for ignition coil processing uses a base plate and concave frame to perform riveting work. When using this riveting machine, the parts are placed directly in the placement slot, which cannot fix the parts, affecting the accuracy and quality of riveting. In addition, the single processing station cannot meet the needs of mass production. Therefore, this riveting machine needs to be improved. Utility Model Content

It can simultaneously rivet multiple silicon steel sheets on two sets of placement tables, improving processing efficiency. The second hydraulic cylinders drive the movable seat to move up and down, while the connecting arm slides inside the fixed frame, ensuring the stability and precision of the movable seat's movement. This allows the riveting head to accurately act on the predetermined riveting position of the silicon steel sheet, ensuring precise control of the riveting pressure and position, which is beneficial for improving the riveting quality of the iron core. The protective plate on the front of the movable seat provides safety protection during the riveting process, preventing damage to operators from debris or accidents generated during processing, thus improving the safety of equipment operation. Simultaneously, the riveting head is threaded into the mounting seat, facilitating the replacement of riveting heads of different shapes and sizes. Attached Figure Description

A placement platform 22 is fixedly connected to the top left side of the processing table 21. A silicon steel sheet 25 is provided on the top of the placement platform 22. A support frame 26 is fixedly connected to the right side of the placement platform 22. A first hydraulic cylinder 27 is fixedly connected to the right side of the support frame 26. A limit plate 28 is fixedly connected to the left side of the first hydraulic cylinder 27. The limit plate 28 is located to the right of the silicon steel sheet 25 and is slidably connected to the top of the placement platform 22. Guide shafts 29 are fixedly connected to the front and rear sides of the limit plate 28 and are slidably connected inside the placement platform 22.

[0022] The bottom of the silicon steel sheet 25 is in contact with the top of the placement platform 22, the left side of the limiting plate 28 is in contact with the right side of the silicon steel sheet 25, and the first hydraulic cylinder 27 is electrically connected to the control panel 24 to facilitate the fixing of the silicon steel sheet 25 through the limiting plate 28.

[0023] The bottom of the limiting plate 28 is in contact with the top of the placement platform 22, and a rubber pad is provided on the left side of the limiting plate 28 to protect the silicon steel sheet 25.

[0024] The support frame 26, the first hydraulic cylinder 27, the limiting plate 28 and the guide shaft 29 are provided in two sets and are symmetrically distributed on the left and right sides of the placement platform 22, so that silicon steel sheets 25 of different sizes can be fixed by setting two sets.

[0025] The placement table 22, silicon steel sheet 25, support frame 26, first hydraulic cylinder 27, limit plate 28 and guide shaft 29 are provided in two sets and symmetrically distributed on the left and right sides of the top of the processing table 21. By setting two sets, two processing stations can be formed, which can improve the efficiency of riveting. Example

[0026] Please see Figure 1-5 Furthermore, based on Embodiment 1, the riveting mechanism 3 further includes a fixed frame 31, which is fixedly connected to the top of the processing table 21. A second hydraulic cylinder 33 is fixedly connected to the top left side of the fixed frame 31. A movable seat 34 is fixedly connected to the bottom of the second hydraulic cylinder 33. A mounting seat 36 is fixedly connected to the bottom of the movable seat 34. A riveting head 37 is threadedly connected inside the mounting seat 36. The riveting head 37 is located on the top of the silicon steel sheet 25. A connecting arm 32 is fixedly connected to the rear side of the movable seat 34. The connecting arm 32 is slidably connected to the inside of the fixed frame 31. A protective plate 35 is fixedly connected to the front side of the movable seat 34.

[0027] The bottom of the riveting head 37 is in contact with the top of the silicon steel sheet 25. The second hydraulic cylinder 33, the movable seat 34, the protective plate 35, the connecting arm 32, the mounting seat 36 and the riveting head 37 are provided in two sets and are symmetrically distributed on the left and right sides of the fixed frame 31. The two sets of riveting heads 37 are located on the top of the two sets of placement platforms 22 respectively, and the two sets of second hydraulic cylinders 33 are electrically connected to the control panel 24 respectively. By setting two sets, the silicon steel sheets 25 on the top of the two placement platforms 22 can be riveted separately.

[0028] In actual operation, when this device is used, and multiple silicon steel sheets 25 need to be riveted to form an iron core during the processing of the ignition coil, the multiple silicon steel sheets 25 are first neatly placed in the middle of the top of the placement platform 22. The two sets of support frames 26, the first hydraulic cylinder 27, the limiting plate 28 and the guide shaft 29, which are symmetrically distributed on the left and right, can apply force from both sides of the silicon steel sheets 25. When the first hydraulic cylinder 27 works, it pushes the limiting plate 28 to move, and the guide shaft 29 ensures that the limiting plate 28 slides smoothly along a straight line to avoid deviation. Under the action of the limiting plate 28, the left and right sides of the silicon steel sheets 25 can be fixed, thereby firmly clamping the multiple silicon steel sheets 25. This effectively prevents the silicon steel sheets 25 from loosening, shifting or tilting during the riveting process, and ensures the neatness of the stacked silicon steel sheets 25, laying a solid foundation for the accuracy of subsequent riveting processing. The rubber pad on the left side of the limiting plate 28 can not only enhance the fixing effect on the silicon steel sheet 25, but also prevent the limiting plate 28 from directly and rigidly contacting the silicon steel sheet 25 and causing damage to the surface of the silicon steel sheet 25. When the fixing is completed, a matching rivet head 37 is selected and threaded into the mounting base 36. The second hydraulic cylinder 33 drives the moving base 34 to move up and down. The connecting arm 32 slides inside the fixed frame 31, ensuring the stability and accuracy of the movement of the moving base 34. This allows the rivet head 37 to accurately act on the predetermined rivet position of the silicon steel sheet 25, ensuring precise control of the rivet pressure and position, which is beneficial to improving the riveting quality of the iron core. When the bottom of the rivet head 37 contacts the top of the silicon steel sheet 25, the riveting work can be carried out. The protective plate 35 on the front side of the moving base 34 can play a safety protection role during the riveting process, avoiding damage to the operator caused by debris or accidents during processing, and improving the safety of equipment operation. The placement table 22, silicon steel sheet 25, support frame 26, first hydraulic cylinder 27, limit plate 28 and guide shaft 29, as well as second hydraulic cylinder 33, moving seat 34, protective plate 35, connecting arm 32, mounting seat 36 and riveting head 37 are all equipped with two sets, which can realize simultaneous processing of two workstations, produce more products per unit time, and greatly improve production efficiency; The riveting head 37 is threaded into the mounting base 36, which facilitates the replacement of riveting heads 37 of different shapes and sizes. Different riveting heads 37 have different bottom dimensions and shapes, but are otherwise the same. The control panel 24 is electrically connected to the first hydraulic cylinder 27 and the second hydraulic cylinder 33, realizing automated control of the entire processing process. Operators can conveniently set and adjust relevant parameters through the control panel 24. The control panel used in this case is model 24: SIMATIC IPC277G.
