Description

Technical Field

[0001] This utility model relates to the field of speaker cover testing equipment, and in particular to a cover skirt testing fixture. Background Technology

[0002] With the development of new energy vehicles, the demand for speakers in cars has also increased. The speaker cover is not only a decorative part and an installation part of the car, but also a key factor in the sound quality of the audio system.

[0003] The cover is generally made of metal, so for multi-curved car interior designs, the cover usually also has a predetermined curve.

[0004] The cover is usually formed with a side skirt to achieve a fit with the mounting position. Therefore, how to inspect the stamped side skirt is the key to the design (i.e. whether it is within the tolerance range). Utility Model Content

[0005] The main purpose of this utility model is to propose a fixture for detecting the skirt edge of a curved face cover, which aims to detect the skirt edge of a curved face cover, and has a simple structure and stable detection.

[0006] To achieve the above objectives, this utility model proposes a faceplate side skirt detection fixture, comprising: The fixture body has an upwardly extending outer stop portion, which is arranged in a closed loop. The inner side of the outer baffle forms a limiting groove, and the bottom wall of the limiting groove is provided with a contoured surface; The height of the outer baffle is appropriate to the height of the cover skirt, and the outer baffle has an inclined arc transition; The outer baffle is provided with concave and convex surfaces spaced apart. The convex surface represents the maximum tolerance of the cover skirt; The concave surface represents the minimum tolerance of the cover skirt.

[0007] By extending the outer stop of the fixture body and using concave and convex surfaces, the inspection of the cover edge skirt is facilitated. When the cover edge skirt is located between the convex and concave surfaces, it meets the inspection requirements; when it is smaller than the concave surface or larger than the convex surface, it exceeds the tolerance range. The detection can be performed by human touch (e.g., during random sampling). When human touch is used, the concave surface will produce a tactile sensation, while the convex surface will not. Alternatively, a visual inspection device can be used. Products that extend beyond the convex surface or are not in the concave surface are judged as unqualified by the horizontal visual device. Its structure is simple and stable, and it effectively solves the problem of the lack of standardized fixtures for the inspection of curved products. Attached Figure Description

[0008] Figure 1This is a three-dimensional schematic diagram of the present invention; Figure 2 This is a cross-sectional view of the present invention.

[0009] In the picture, 1 is the main body of the fixture, 10 is the outer stop, 11 is the convex surface, 12 is the concave surface, 2 is the limiting groove, and 3 is the transition surface. Detailed Implementation

[0010] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0011] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0012] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0013] like Figures 1 to 2 As shown, a faceplate skirt detection fixture includes: The fixture body 1 has an upwardly extending outer stop 10, which is arranged in a closed loop. The inner side of the outer baffle 10 forms a limiting groove 3, and the bottom wall of the limiting groove is provided with a contoured surface; The height of the outer baffle 10 is adapted to the height of the faceplate skirt, and the outer baffle 10 has an inclined arc transition; The outer baffle 10 is provided with concave and convex surfaces spaced apart. The convex surface represents the maximum tolerance of the cover skirt; The concave surface represents the minimum tolerance of the cover skirt.

[0014] By extending the outer stop 10 of the fixture body 1 and by setting the concave surface 11 and the convex surface 12, the inspection of the cover edge skirt is facilitated. When the cover edge skirt is located between the convex surface and the concave surface, it meets the inspection requirements; when it is smaller than the concave surface or larger than the convex surface, it exceeds the tolerance range. The detection can be performed by human touch (e.g., during random sampling). When human touch is used, the concave surface will produce a tactile sensation, while the convex surface will not. Alternatively, a visual inspection device can be used. Products that extend beyond the convex surface or are not in the concave surface are judged as unqualified by the horizontal visual device. Its structure is simple and stable, and it effectively solves the problem of the lack of standardized fixtures for the inspection of curved products.

[0015] Specifically, the contoured surface is an inclined or curved surface, which fits the shape of the cover.

[0016] In this embodiment of the invention, the contouring surface is a smooth surface.

[0017] Specifically, the main body 1 of the fixture is integrally machined by CNC, thereby ensuring the integrity of the structure.

[0018] In this embodiment of the utility model, the fixture body 1 is made of aluminum alloy or plastic material.

[0019] Specifically, a transition surface is provided between the concave surface and the convex surface.

[0020] In this embodiment of the utility model, the stop is further provided with a clearance groove (not shown), which is used to avoid the vertical strips of the side skirt.

[0021] Specifically, the contoured surface is detachably fitted with a thin film. In one embodiment, the use of the thin film can achieve tolerance adjustment, thereby improving the inspection applicability of the fixture.

[0022] In this embodiment of the invention, the transition surface is a vertical surface or an inclined surface, thereby avoiding scratches caused by sharp corners during manual inspection.

[0023] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
