Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to a riveting press for processing ignition coils. Background Technology

[0002] The ignition coil is a core component of an automotive ignition system. Its main function is to boost the low-voltage current supplied by the vehicle battery to a high voltage, thereby igniting the air-fuel mixture in the engine cylinders and ensuring the engine starts and runs normally. Because the ignition coil must withstand complex environments such as high temperature and high pressure during operation, the connections of its internal components must be robust and reliable, requiring extremely high precision in manufacturing processes. Riveting, as one of the key steps in the ignition coil assembly process, is mainly used to securely connect the outer casing to the internal components, placing stringent requirements on machining accuracy and stability.

[0003] Utility model patent CN 214133804 U discloses a riveting machine for processing ignition coils, including a base plate, a concave frame, a threaded rod, a turntable, a slider, a horizontal plate, a spring, a second connecting block, a fixed seat, and a punch head. This device rotates the turntable to drive the threaded rod, causing the punch head to move downwards to complete the riveting operation. A spring is used for reset, and a fastening bolt locks the punch head to prevent loosening or damage to the workpiece. While this equipment has advantages in controlling the punching pressure and replacing the punch head, in practical applications, it has been found that its positioning device for carrying the ignition coil can only perform the fixing and riveting operation of a single coil, failing to meet the continuous processing needs of multiple ignition coils. This results in low equipment utilization, limited output per unit time, and severely impacts overall production efficiency.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a riveting machine for ignition coil processing. This equipment should significantly improve the continuity and stability of the riveting process, while also possessing multi-station positioning and automatic feeding functions to better meet the demands of modern high-volume, high-precision production, providing strong support for the continued development of the automotive electronics manufacturing industry. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a riveting machine for processing ignition coils, including a riveting machine, a movable frame, and a mounting bracket;

[0007] The movable frame is connected to the top of the riveting machine, and the mounting bracket is set on the top of the movable frame and connected to the side wall of the riveting machine on both bottom sides.

[0008] The top of the mounting bracket is connected to a stamping cylinder, and the bottom is provided with a stamping head, with the output end of the stamping cylinder connected to the top of the stamping head.

[0010] The top of the support plate is bolted to a lower mold base, and the top of the lower mold base has several placement slots.

[0011] The movable frame is made of metal, and its bottom is fixedly connected to the top of the riveting machine with bolts.

[0012] The riveting machine has sliding grooves on both sides of its top, and a movable plate is connected to the bottom of the bearing plate. Sliding blocks that are adapted to the sliding grooves are connected to both sides of the bottom of the movable plate.

[0013] The length of the movable frame is the same as the length of the riveting machine, and the length of the movable frame is twice the length of the bearing plate.

[0014] The horizontal moving component includes a lead screw rotatably connected inside the moving frame. One end of the moving frame is equipped with a drive motor that cooperates with the lead screw, and the moving plate is threadedly engaged with the lead screw.

[0015] The movable frame is provided with guide rods on both sides, and the two ends of the guide rods are connected to the side wall of the movable frame through mounting plates. The two sides of the bearing plate are connected to sliding sleeves that slide with the guide rods through connecting frames.

[0032] Example 2

[0033] Please see Figure 1-5 As shown in this embodiment, a riveting machine for processing ignition coils has a movable frame 2 made of metal.

This design not only enhances the overall strength of the equipment but also ensures that no loosening or deformation occurs during high-frequency operation, thus improving the reliability and service life of the equipment.

[0034] The length of the movable frame 2 is the same as the length of the riveting machine 1, and the length of the movable frame 2 is twice the length of the support plate 3.
