Description

Technical Field

[0001] This invention belongs to the field of breather plug technology, specifically relating to a breather plug plunger riveting and positioning device. Background Technology

[0002] The main structure of a certain product's vent plug consists of a shell with a spring and baffle inside, which are then inserted into a plunger and riveted to secure the plunger head. Due to the vent plug's compact structure, there is insufficient space for manual riveting, resulting in poor consistency. Using a traditional riveting machine with excessive pressure cannot guarantee the riveting quality.

[0003] Currently, these vent plugs have a compact structure and high venting pressure, and are used for venting transmission components under special conditions. However, their application is limited to small quantities, and there are no scenarios for mass production. Current technical solutions mainly rely on manual operation, which is inefficient. There is an urgent need for a reliable device that can precisely control the stroke and rivet head shape. Summary of the Invention

[0004] This invention provides a vent plug plunger riveting and positioning device to achieve effective positioning and riveting of the vent plug plunger.

[0005] To solve the above technical problems, the present invention provides a vent plug plunger riveting and positioning device, characterized in that it includes a positioning screw plug, a fixing sleeve, a pressure cap, a rivet head, and a pressing rod; the upper end face of the pressure cap is provided with a through hole, the vent body is inserted into the fixing sleeve from below, the spring and the vent plunger are sequentially inserted into the vent body, the positioning screw plug is used to press the vent plunger from below and is threadedly connected to the fixing sleeve, the gasket is inserted into the vent body and located above the vent plunger, the pressing rod is used to press the gasket into place and then the pressure cap is tightened to fix the external thread of the fixing sleeve, the vent plunger extends out of the through hole of the pressure cap and is riveted into shape by the action of the pressing rod.

[0006] Beneficial effects: This invention can complete the riveting operation of vent plugs and similar structural components. After riveting, the structure formed at the riveted part is uniform and the connection is reliable, ensuring the consistency of the product. Attached Figure Description

[0007] Figure 1 Schematic diagram of the vent plug structure; Figure 2 Schematic diagram of the structure of this invention; The components include: 1. Positioning screw plug; 2. Fixing sleeve; 3. Pressure cap; 4. Rivet head; 5. Extrusion rod. Detailed Implementation

[0008] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below.

[0009] The present invention proposes a vent plug plunger riveting and positioning device, comprising a positioning screw plug 1, a fixing sleeve 2, a pressure cap 3, a rivet head 4, and a pressing rod 5; When in use, first install the vent body into the fixing sleeve, then install each internal part in sequence and fix it with the positioning screw plug. Finally, install the part washer into the vent body, use the extrusion rod to push the washer into place, and then tighten the cover to fix it with the external thread of the fixing sleeve 2. The rivet head 4 is installed on the riveting machine and acts on the extrusion rod 5 to perform riveting.

[0010] This invention utilizes positioning screws, fixing sleeves, and pressure caps to achieve multi-layer positioning and fixing. During the assembly process, the device uses a spring to retract and position the component, exposing the riveting area for riveting. This device can be used to complete the riveting of vent plugs and similar structural components. After riveting, the structure formed at the riveting area is uniform, the connection is reliable, and the consistency of the product is guaranteed.

[0011] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

Claims

1. A vent plug plunger riveting and positioning device, characterized in that: The device includes a positioning screw plug, a fixing sleeve, a gland, a rivet head, and a pressing rod. The upper end face of the gland has a through hole. The vent body of the vent plug is inserted into the fixing sleeve from below.
