Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a tooling for attaching foam to automotive speakers. Background Technology

[0002] With the development of technology, the production and processing of car horns is becoming increasingly automated, with automated processes for picking, moving, and assembling parts, thereby reducing the need for manual labor.

[0003] Car speaker foam is a crucial component for ensuring the waterproof function of car speakers, requiring a seamless and fold-free fit. However, the foam used in car speakers is ring-shaped and soft, making it difficult to apply completely smoothly, resulting in time-consuming and laborious manual application. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a foam mounting tool for car speakers, which makes foam mounting more convenient, saving time and effort.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a car speaker foam attaching tooling, having a base body, with foam grooves concentrically arranged in the circumferential direction of the base body, a clearance portion on the outer periphery of the foam groove, a positioning post and a positioning hole at the clearance portion, and a top material hole on the inner side of the base body located in the foam groove.

[0006] In the above technical solution, the foam groove is provided with three clearance parts, which are evenly distributed in the circumferential direction of the foam groove.

[0007] In the above technical solution, positioning posts are provided at all three clearance parts, and positioning holes are provided at two clearance parts.

[0008] In the above technical solution, the inner side of the foam groove is provided with a top material step, and the top material step is arranged along the outer periphery of the top material hole.

[0009] In the above technical solution, the height of the inner top step of the foam groove is less than the height of the outer wall of the foam groove.

[0010] In the above technical solution, the outer side of the clearance portion is provided with an arc-shaped outer edge.

[0011] In summary, the advantages of this utility model over traditional methods are as follows: This utility model features a foam groove on the substrate that matches the shape of the speaker foam, along with a corresponding clearance portion. This allows the speaker foam to be easily inserted into the foam groove during installation. The positioning post passes through the foam and inserts into the corresponding hole on the speaker for accurate positioning. Furthermore, a ejector hole is provided in the middle of the foam groove, allowing excess material to be ejected during foam application, further enhancing convenience. Attached Figure Description

[0012] Other objects, features and advantages of this invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

[0018] The following labels are used: 100, substrate; 200, foam groove; 300, clearance part; 310, positioning post; 320, positioning hole; 400, ejector hole; 410, ejector step; 500, speaker foam; 510, arc-shaped protrusion; 520, sticker; 600, speaker. Detailed Implementation

[0019] Based on the preferred embodiments of this utility model, and through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.

[0020] Referring to the following figures, the present invention will be further described: A car speaker foam attaching fixture has a base 100, an annular foam groove 200 is concentrically provided in the circumferential direction of the base 100, a plurality of clearance portions 300 are provided on the outer periphery of the foam groove 200, a positioning post 310 and a positioning hole 320 are provided at the clearance portion 300, and a top material hole 400 is provided on the inner side of the base 100 located in the foam groove 200.

[0021] like Figure 1 , 2 As shown, the foam groove 200 has three clearance portions 300 on its outer periphery, which are evenly distributed in the circumferential direction of the foam groove 200. These clearance portions are used to avoid the arc-shaped protrusion 510 on the outer periphery of the speaker foam 500, ensuring that the tooling is accurately aligned with the speaker body 600 during installation, thereby improving the fitting accuracy and work efficiency.

[0022] like Figure 2As shown, positioning holes 320 are provided at the three clearance portions 300. The positioning posts 310 and positioning holes 320 correspond to the corresponding holes and posts on the speaker foam 500, respectively. The purpose of providing only two positioning holes is to ensure the accurate placement orientation of the speaker foam 500.

[0023] like Figure 1 , 2 As shown, the inner side of the foam groove 200 is provided with a top material step 410. The top material step 410 is arranged along the outer periphery of the top material hole. The arrangement of the top material step 410 can create a height difference between the speaker foam 500 body and the excess part in the middle during assembly, and automatically push out the excess part in the middle of the speaker foam 500.

[0024] like Figure 1 As shown, the height of the inner top step 410 of the foam trough 200 is less than the height of the outer wall of the foam trough 200.

[0025] like Figure 2 , 5 As shown, the outer side of the clearance portion 300 is provided with an arc-shaped outer edge, the shape of which is consistent with the arc-shaped protrusion 510 of the speaker foam 500.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
