Description

Technical Field

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

[0002] As we all know, with the development of automotive gasoline engines towards higher speeds, higher compression ratios, higher power, lower fuel consumption, and lower emissions, traditional ignition systems are no longer suitable for the requirements. The core components of an ignition system are the ignition coil and the switching device. By increasing the energy of the ignition coil, the spark plug can generate a spark with sufficient energy. This is the basic condition for an ignition system to adapt to the operation of modern engines. A typical ignition coil contains two sets of coils: a primary coil and a secondary coil. The primary coil uses thicker enameled wire, while the secondary coil uses thinner enameled wire.

[0003] In the existing technology, during the processing of ignition coil components, a riveting press is required to stamp the parts. However, when the existing riveting press is used to stamp the ignition coil, the cylinder has a large impact force. Prolonged stamping makes it difficult for the cylinder to remain stable, which will affect the processing quality of the ignition coil. Utility Model Content

[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 1-4The riveting machine for processing ignition coils according to this utility model includes a worktable 1. The upper end of the worktable 1 is provided with a base 8 and a support frame 2. The upper end of the base 8 is provided with a lower die holder 11, which has multiple processing slots 12. The lower end of the worktable 1 is provided with multiple support rods, and a base plate is provided between the support rods. The support frame 2 is located on one side of the base 8. The top of the support frame 2 is provided with a lifting cylinder 3, and the bottom end of the lifting cylinder 3 is provided with a mounting plate 6. The mounting plate 6 is fixed to the support frame with screws. At the top of the frame 2, the output end of the lifting cylinder 3 is provided with a lifting rod. The bottom end of the lifting rod is provided with a punch mounting seat 7 located above the lower die base 11. The lower end of the punch mounting seat 7 is provided with multiple punch assemblies 10 located above the processing groove 12. The upper end of the base 8 is provided with multiple limiting rods 9. The limiting rods 9 are located on both sides of the lower die base 11 and the punch mounting seat 7. The outer walls of the lower die base 11 and the punch mounting seat 7 are provided with limiting grooves 20. The limiting grooves 20 cooperate with the limiting rods 9. The lower end of the limiting rods 9 is located at... The upper end of the base 8, the upper end of the limiting rod 9 is located at the top of the support frame 2, and the lower end of the limiting rod 9 is detachable from the base 8. The upper end of the base plate is provided with a lifting device 18, and the output end of the lifting device 18 is provided with a lifting rod 16. The lower end of the base 8 is provided with a bottom groove 14 communicating with the processing groove 12. The upper end of the lifting rod 16 is provided with a bearing plate 15 located inside the bottom groove 14. The ignition coil fixture is placed inside the processing groove 12, at which time ignition... The coil fixture is positioned at the top of the support plate 15. The ignition coil is then placed above the ignition coil fixture. The lifting cylinder 3 is activated, causing the lifting rod to lower the punch mounting seat 7. The punch assembly 10 then descends, thus achieving the riveting of the ignition coil to the ignition coil fixture. After riveting is completed, the lifting device 18 is activated, causing the lifting rod 16 to descend, further lowering the support plate 15 inside the bottom groove 14. At this point, the finished product in the processing groove 12 descends along with the support plate 15 to the bottom of the worktable 1, making it convenient for workers to remove it.

[0024] When the punch mounting base 7 is raised or lowered, the limiting rod 9 provides a limiting effect on both sides of the punch mounting base 7, thereby improving the stability of the lifting rod during use. The limiting groove 20 provides a limiting effect between the punch mounting base 7 and the limiting rod 9, making the punch mounting base 7 rise and fall more smoothly along the limiting rod 9 and ensuring the processing quality of the ignition coil.

[0025] In this structure, the lifting cylinder 3 lacks a limiting structure at the top of the support frame 2, which will affect the stability of the lifting cylinder 3 under long-term use. The upper end of the support frame 2 is provided with a fixing sleeve 4 through which the lifting cylinder 3 passes. The fixing sleeve 4 is provided with reinforcing rods 5 on both sides. The bottom end of the reinforcing rods 5 is fixed to the support frame 2, and the reinforcing rods 5 and the support frame 2 are detachable. Through the fixing sleeve 4 and the reinforcing rods 5, a limiting effect can be provided for the lifting cylinder 3 at the top of the support frame 2, making the lifting cylinder 3 more firmly installed and improving the stability of the lifting cylinder 3 during use.

[0026] When disassembling the lifting cylinder 3, the fixing sleeve 4 also needs to be disassembled. The two ends of the limiting rod 9 are provided with fixing plates 13. The fixing plates 13 are fixed to the upper end of the base 8 and the top of the support frame 2 respectively by screws. The bottom end of the reinforcing rod 5 is provided with a limiting plate. The limiting plate is fixed to the upper end of the support frame 2 by screws. Loosening the screws on the limiting plate can separate the reinforcing rod 5 from the support frame 2, thereby allowing the fixing sleeve 4 to be separated. Loosening the screws on the fixing plate 13 can separate the two ends of the limiting rod 9. The structure is simple and the operation is convenient.

[0027] There is a certain friction between the limiting groove 20 and the limiting rod 9. If the friction is too large, it will affect the smoothness of the punch mounting seat 7 when it is raised and lowered. The inner wall of the limiting groove 20 is provided with multiple balls 19, and the outer wall of the balls 19 is attached to the outer wall of the support frame 2, so that the punch mounting seat 7 is raised and lowered more smoothly.

[0028] Furthermore, the lifting device 18 uses a hydraulic cylinder, which has the advantages of high stability, large load-bearing capacity, and is not easily damaged.

[0029] To improve the stability of the support plate 15 during lifting, the lower end of the support plate 15 is provided with a plurality of positioning rods 17 that penetrate the bottom plate.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
