[0023] As Figures 1-5 Indicated, the utility model discloses a kind of position degree gauges of vehicle loudspeaker to solve the inconvenient, relatively low efficiency of position degree detection of the upper end face of existing vehicle loudspeaker, including bottom plate 1, the upper side of the bottom plate 1 is provided with first positioning seat 7 and second positioning seat 4 side by side, first positioning seat 7 and second positioning seat 4 are arranged with detection ring 3 on the upper side, the middle part of detection ring 3 is provided with position degree annular detection part 31, the upper side of the bottom plate 1 is provided with loudspeaker positioning assembly in the position corresponding to position degree annular detection part 31, the loudspeaker positioning assembly is positioned to the loudspeaker to be measured, so that the loudspeaker to be measured is located just below position degree annular detection part 31, the upper end face of the loudspeaker to be measured and the lower side of position degree annular detection part 31 form vertical position degree detection gap B, the upper side edge of the loudspeaker to be measured and the inner hole side wall of position degree annular detection part 31 form horizontal position degree detection gap A, by installing and positioning a detection ring 3, it can be used as the reference object of the upper end face position degree of loudspeaker to be measured, horizontal position degree detection gap A and vertical position degree detection gap B are cooperated with go-stop gauge to quickly and accurately detect the upper end face position degree of loudspeaker to be measured, simplify the operation of position degree detection, improve efficiency.

[0024] Specifically, when placing the speaker to be tested, the detection ring 3 is in the removed state, and the speaker positioning assembly is used to quickly position the speaker to be tested. The speaker positioning assembly can also detect and position the installation position of the speaker to be tested. After positioning the speaker to be tested, the detection ring 3 is placed in position, and then the go-no-go gauge is used to detect 8 points on the horizontal position degree detection gap A and 8 points on the vertical position degree detection gap B, respectively. When measuring, the go-no-go gauge ensures that it is flat with the detection ring 3.

[0025] In this embodiment, as shown in Figure 1 The speaker positioning assembly includes two first positioning pressure seats 6 located in front of the detection ring 3 and two second positioning pressure seats 2 located in the rear of the detection ring 3. The inner side of each of the first positioning pressure seat 6 and the second positioning pressure seat 2 is provided with a positioning seat 11. A first pressure clamp 12 is installed on each of the first positioning pressure seat 6 and the second positioning pressure seat 2. The first pressure clamp 12 is used to press the speaker to be tested on the positioning seat 11. The four positioning seats 11 cooperate with the first positioning pressure seat 6 and the second positioning pressure seat 2 to quickly position and press the speaker to be tested.

[0026] In this embodiment, the detection ring 3 further includes a first extension rod 32 and a second extension rod 33 extending horizontally on both sides of the position degree annular detection part 31. The first extension rod 32 and the second extension rod 33 have different widths to ensure that the detection ring 3 can be quickly placed and positioned in the correct direction and cannot be placed in the wrong direction.

[0027] In this embodiment, as shown in Figures 1-2 The end of the first extension rod 32 and the second extension rod 33 is provided with a side embedding block 34 extending to both sides.

The second pressure clamp 8 presses the first extension rod 32 or the second extension rod 33. The two ends of the detection ring 3 are positioned by pressing the detection ring 3 with the second pressure clamp 8 to prevent movement.

[0029] In this embodiment, if Figure 1 As shown, a detachable go / no-go gauge 5 is positioned on the base plate 1, so that the go / no-go gauge 5 can be quickly taken out to detect the horizontal position detection gap A and the vertical position detection gap B.

[0030] The first clamp 12 and the second clamp 8 are manual or pneumatic clamps, which can quickly and easily clamp the test ring 3 and the speaker to be tested. Handles 9 are installed on both sides of the upper end of the base plate 1 to facilitate the movement of the entire position gauge.

[0031] In this embodiment, the hollow hole 10 in the middle of the bottom plate 1 is coaxial with the position annular detection portion 31, which facilitates the avoidance of air at the bottom of the speakers to be tested of different shapes.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0034] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
