Description

Technical Field

[0001] This invention relates to the field of spark plug assembly technology, and more specifically, to a hot and cold riveting machine for ring-shaped spark plug housings. Background Technology

[0002] Spark plugs are the core ignition component of a car engine, responsible for generating an electric spark in the combustion chamber to ignite the air-fuel mixture. Proper assembly requires ensuring clean threads, accurate clearance, and tightening to the specified torque to achieve reliable sealing and efficient ignition. Correct assembly ensures smooth engine operation, reduces fuel consumption, and improves power response. Regularly inspecting and properly replacing spark plugs is crucial for maintaining engine performance and extending its lifespan.

[0003] Traditional spark plug assembly relies heavily on manual labor or semi-automatic equipment, which results in low efficiency, high labor intensity, and a high risk of missing parts, misalignment, and component damage, making it difficult to guarantee product consistency under mass production conditions.

[0004] Therefore, in view of this, we will study and improve the existing structure and provide a ring-shaped shell cold and hot riveting machine in order to achieve a more practical purpose. Summary of the Invention

[0005] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this invention is to provide a ring-shaped spark plug assembly cold and hot riveting machine, which not only significantly reduces the cost and error of manual sampling inspection, improves assembly efficiency, and reduces labor intensity, but also ensures the consistency of spark plug assembly and the reliability of the final product. It is particularly suitable for the large-scale manufacturing of spark plugs with strict requirements for airtightness and ignition performance.

[0006] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0007] A ring-type hot and cold riveting machine for housing assembly includes an integrated frame, wherein the integrated frame is sequentially fixed from one end to the other with: Spark plug material platform, with a material detection platform provided on one side of the spark plug material platform; A feeding and processing structure, wherein a processing and testing table is provided on one side of the feeding and processing structure; A spark plug ceramic body mounting structure, wherein a spark plug ceramic body detection structure is provided on one side of the spark plug ceramic body mounting structure; A wire ring placement structure, wherein a wire ring detection structure is provided on one side of the wire ring placement structure; A powder ring placement structure, wherein a powder ring detection structure is provided on one side of the powder ring placement structure, and a powder ring pressing structure is provided on one side of the powder ring detection structure; An electrostatic dust removal structure is located on one side of the powder ring placement structure; The discharge structure is located on one side of the electrostatic dust removal structure.

[0008] Furthermore, a door panel is hinged to the side of the integrated frame, and one end of the door panel is magnetically attached to the integrated frame.

[0009] Furthermore, the feeding and processing structure includes two feeding trays, and a first cylinder and a second cylinder are provided above the conveying track of each feeding tray.

[0010] Furthermore, the first cylinder is located directly above the second cylinder.

[0011] Furthermore, a scale is provided on the side of the feeding tray, and the bottom end of the scale is fixed to the integrated frame.

[0012] Furthermore, a flipping structure and a pointed pre-bending treatment structure are also provided between the powder ring placement structure and the electrostatic dust removal structure.

[0013] Furthermore, the detection methods for the material detection station, processing detection station, spark plug ceramic body detection structure, wire ring detection structure, and powder ring pressing structure are all image detection.

[0014] Furthermore, the discharge structure includes a positive product discharge structure and a negative product discharge structure.

[0015] 3. Beneficial Effects Compared with the prior art, the advantages of this invention are: ① This solution, through a dedicated placement structure and corresponding high-sensitivity image detection unit arranged sequentially along the production line, achieves real-time visual monitoring and data comparison of each assembly stage; any misalignment, omission, or component damage in any process will be immediately identified and automatically sorted in conjunction with the discharge structure, effectively preventing defective products from flowing into subsequent workstations or mixing into finished products; this not only significantly reduces the cost and error of manual sampling, improves assembly efficiency, and reduces labor intensity, but also ensures the consistency of spark plug assembly and the reliability of the final product, making it particularly suitable for the large-scale manufacturing of spark plugs with stringent requirements for airtightness and ignition performance; ② This solution utilizes a modular, integrated frame design. The hollow interior facilitates pipeline and component arrangement, while the magnetic hinged side panels make internal maintenance and parts replacement extremely convenient. Simultaneously, the production line incorporates multi-functional processing units at key workstations. For example, after the powder ring is placed, it integrates pressing and inspection; before electrostatic dust removal, a flipping structure and a tip pre-bending structure are added. This allows for one-stop electrode tip shaping and surface cleaning after the spark plug has completed basic assembly, shortening process flow time and avoiding damage that may result from repeated handling. This integrated and flexible design enables the production line to adapt to continuous high-speed production while also facilitating adjustments to process parameters according to product specifications, balancing efficiency, flexibility, and process integrity.
