[0001] The utility model relates to the technical field of automobile ignition coil production devices, in particular to a clamping fixture for automobile ignition coil winding. Background Art

[0002] The ignition coil consists of an ignition coil, an ignition coil cover, and an ignition coil connector. The ignition coil converts low voltage into high voltage, driving the spark plug to produce a spark and start the engine. Installed on top or to the side of the engine, close to the spark plug, the ignition coil is available in open-circuit and closed-circuit configurations. It converts low voltage electricity through windings to high voltage, which is then applied to the front of the spark plug via high-voltage wires to ignite the engine. During ignition coil manufacturing, a clamp is required to hold the wires in place.

[0003] The existing technology for fixing automobile ignition coils has cumbersome fixing steps, a relatively complex clamping structure, high cost, and inconvenient operation, which has a certain impact on processing efficiency. In addition, when fixing the entire line, excessive fixing force can easily cause wear on the automobile ignition coil, resulting in unnecessary losses. Utility Model Content

[0021] like Figure 1-Figure 3 As shown, the embodiment of the present utility model provides a clamping fixture for winding an automobile ignition coil, comprising:

[0022] The support frame 1 has a support roller 2 rotatably connected to the side wall of the support frame 1, and a baffle 17 is fixedly connected to the side wall of the support roller 2 to limit the ignition coil. A group of bolts 3 are threaded through the support frame 1. A rotating motor 4 is fixedly installed on the side wall of the support frame 1. The rotating end of the rotating motor 4 rotates through the support frame 1 and is fixedly connected to the support roller 2. A protective shell 16 is fixedly connected to the side wall of the support frame 1. The protective shell 16 matches the rotating motor 4. The protective shell 16 can protect the rotating motor 4 and prevent the rotating motor 4 from being damaged by external interference.

[0023] The fixing assembly includes a working chamber 5 opened on the support roller 2, the inner wall of the working chamber 5 is rotatably connected to the first bevel gear 6, the support roller 2 is provided with a rotating chamber 9, the inner wall of the rotating chamber 9 is fixedly connected to the servo motor 10, and the inner wall of the rotating chamber 9 is provided with a group of heat dissipation holes to achieve heat dissipation in the rotating chamber 9 to prevent the servo motor 10 from being damaged by excessive temperature. The rotating end of the servo motor 10 is fixedly connected to the first bevel gear 6, and a group of clamping assemblies are installed on the support roller 2. The clamping assembly includes a sliding groove 7 opened on the support roller 2, and a sliding block 8 is slidably connected in the sliding groove 7;

[0024] The inner wall of the working chamber 5 is rotatably connected to a second bevel gear 11, and the second bevel gear 11 and the first bevel gear 6 are meshed with each other. The inner wall of the sliding groove 7 is rotatably connected to a threaded rod 12, and the threaded rod 12 is fixedly connected to the second bevel gear 11. The threaded rod 12 is threadedly connected to the sliding block 8. A buffer assembly is installed on the sliding block 8, and a clamping plate 13 is installed on the buffer assembly. A set of clamping plates 13 are provided with anti-slip grooves, which improve the friction between the clamping plates 13 and the inner wall of the ignition coil, thereby improving the stability of the ignition coil.

[0025] The buffer assembly includes a buffer cavity 14 opened on the sliding block 8, a group of spring frames 15 are fixedly connected to the inner wall of the buffer cavity 14, a movable plate is slidably connected in the buffer cavity 14, the movable plate is fixedly connected to the group of spring frames 15, the movable plate is fixedly connected to the support rods, a group of support rods all slide through the sliding block 8, and the clamping plate 13 is fixedly connected to the group of support rods.
