[0019] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0020] The embodiment of the utility model relates to a test fixture for a speaker grille on a left A-pillar trim panel, such as Figure 1-6 As shown, it includes a gauge base plate 1, a ring-shaped enclosure 3 is installed in the middle of the upper end of the gauge base plate 1, a plurality of support blocks 5 are arranged around the edge of the inner wall of the enclosure 3, a snap-on through hole 9 is opened on the support block 5, an edge contour fitting surface 7 is arranged on the inner side of the upper end of the enclosure 3, a depth pin surface detection device 6 is installed on each of the front and rear sides of the upper end of the gauge base plate 1, a plurality of lower hole position detection devices 8 are arranged in the enclosure 3 at the upper end of the gauge base plate 1, and a plurality of clamping devices 4 are arranged around the enclosure 3 at the upper end of the gauge base plate 1.

[0021] During installation, first place the speaker grille body 20 on the enclosure 32, and the edge contours 24 around the speaker grille body 20 are fitted with the edge contour fitting surface 7 on the inner side of the upper end of the enclosure 32. If they are completely fitted and the speaker grille body 20 does not shake, the edge contour 24 detection is qualified, otherwise the edge contour 24 detection is unqualified. The multiple buckles 21 at the lower end of the speaker grille body 20 are respectively inserted into the buckle through holes 9 of their respective support blocks 5. If all the buckles 21 are inserted into the corresponding buckle through holes 9 one by one, it proves that the position detection of the above-mentioned multiple buckles 21 is qualified, otherwise the position detection of the buckles 21 is unqualified. When the position of the buckles 21 and the edge contours 24 are both qualified, start the multiple clamping devices 4 to press the upper edge of the speaker grille body 20 to achieve the compression and positioning of the speaker grille body 20, and then use the depth pin surface detection device 6 and the lower hole position detection device 8 for detection.

[0022] A handle 2 is installed on each side of the inspection tool base plate 1, and the handle 2 is provided to facilitate the transportation of the entire inspection tool.

[0023] The clamp device 4 is a quick clamp; the quick clamp is a new manual clamp that can accurately position and quickly clamp. The quick clamp is an existing component and can be directly purchased on the market.

[0024] The depth pin surface detection device 6 includes a pin surface detection seat 10 and a detection rod 11. The detection rod 11 that slides forward and backward is installed in the upper part of the pin surface detection seat 10. The detection rod 11 is provided with a pin surface contact portion 12 at one end close to the enclosure 3. The other end of the detection rod 11 is provided with a spherical hand grip 13; the other end of the detection rod 11 is screwed to the hand grip 13 by a thread. When the depth pin surface detection device 6 is detecting, hold the hand grip 13 and push the detection rod 11 forward and backward. When the hand grip 13 contacts the pin surface detection seat 10, if the pin surface contact portion 12 at one end of the detection rod 1 can be butted against the end face of the U-shaped buckle 23, the U-shaped buckle 23 is qualified, otherwise the detection is unqualified.

[0025] A wear-resistant guide sleeve 14 is horizontally inserted into the upper part of the pin surface detection seat 10. A locking screw 18 is screwed onto the upper end of the pin surface detection seat 10. The lower end of the locking screw 18 presses the wear-resistant guide sleeve 14. The detection rod 11 is installed in the wear-resistant guide sleeve 14 and slides back and forth.

[0026] The lower hole position detection device 8 includes a hole position detection seat 15 and a detection pin 16. The hole position detection seat 15 is equipped with a detection pin 16 that can slide up and down. The lower end of the detection pin 16 passes through the bottom plate 1 of the inspection tool and is equipped with a hand grip 13. The upper end of the hand grip 13 is equipped with a limit sleeve 19 that is sleeved outside the detection pin 16. The upper end of the detection pin 16 is provided with a hole position plug 17. The lower end of the detection pin 16 and the hand grip 13 are also screwed together. The limit sleeve 19 limits the maximum height of the detection pin 16. When the upper end of the limit sleeve 19 contacts and fits with the lower end of the bottom plate 1 of the inspection tool, it indicates that the detection pin 16 has risen to the highest height. When the lower hole position detection device 8 is detecting, hold the hand grip 13 and push the detection pin 16 upward. If the hole position plug 17 at the upper end of the detection pin 16 can be inserted into the circular through hole 25 at the lower end of the plug 22, the plug 17 is tested qualified, otherwise it is unqualified.

[0027] How to detect the sliding range of the pin 16 up and down? A long strip groove can be opened on the side wall of the detection pin 16, and a limit screw inserted into the long strip groove is installed on the side of the hole position detection seat 15.

[0028] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0030] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0031] The above is a detailed introduction to a test fixture for the speaker grille on the left A-pillar trim provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technicians in this field, according to the ideas of the present application, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present application.
