[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The embodiment of the present application discloses a tooling fixture for loudspeaker production, including a clamping platform 1, at least three groups of clamping mechanisms distributed in a circular array are arranged on the upper surface of the clamping platform 1, the clamping mechanisms include an electric push rod 2, a movable seat 3, a first clamping seat 4 and a second clamping seat 9, the electric push rods 2 are fixedly mounted on the upper surface of the clamping platform 1, the movable seats 3 are located at the telescopic end of the electric push rod 2, the first clamping seat 4 is located at the bottom of the movable seat 3, and the second clamping seat 9 is installed on the top of the movable seat 3 by setting a moving mechanism, so that the second clamping seat 9 can move along the telescopic direction of the electric push rod 2, so that the horizontal distance between the second clamping seat 9 and the first clamping seat 4 matches the difference in radial length of the loudspeaker at different heights.

[0019] In this embodiment, when clamping the speaker basket, the basket is placed on the clamping platform 1 and located in the middle of the three groups of clamping mechanisms. By driving the electric push rod 2 to extend, the first clamping seat 4 and the second clamping seat 9 are moved so that the first clamping seat 4 and the second clamping seat 9 are in contact with the side wall of the basket. Therefore, the three groups of first clamping seats 4 can clamp and fix the bottom of the basket, and the three groups of second clamping seats 9 can clamp and fix the top of the basket, thereby improving the stability of the basket.

[0020] Furthermore, the moving mechanisms include a guide rod 8 and a first spring 5. A groove 16 adapted to the guide rod 8 is opened on the top of the moving seat 3. The guide rod 8 is installed in the groove 16 to form a moving pair. One end of the guide rod 8 is fixedly connected to the second clamp seat 9. The first spring 5 is sleeved on the outer surface of the guide rod 8. When the second clamp seat 9 moves, the first spring 5 is in an extended or compressed state.

[0021] Furthermore, a slide groove 11 is provided on the surface of the movable seat 3, a limit rod 14 is arranged inside the slide groove 11, a connecting groove 17 is provided between the groove body 16 and the slide groove 11, the upper end of the limit rod 14 is fitted inside the connecting groove 17, and a driving mechanism is provided in the slide groove 11, which can drive the limit rod 14 to move inside the connecting groove 17, so that the limit rod 14 contacts or separates from the guide rod 8.

[0022] Furthermore, the driving mechanism includes a wedge-shaped top block 12, a second spring 10 and an L-shaped push plate 13. The wedge-shaped top block 12 is fixedly mounted on the lower end of the limit rod 14, the second spring 10 is sleeved on the surface of the limit rod 14, the L-shaped push plate 13 is arranged below the wedge-shaped top block 12, and the top of the L-shaped push plate 13 contacts the inclined surface of the wedge-shaped top block 12, and a horizontal displacement mechanism is arranged between the L-shaped push plate 13 and the first clamp seat 4.

[0023] Furthermore, the horizontal displacement mechanism includes a connecting rod 6, a connecting plate 7 and a third spring 15. One end of the connecting rod 6 is fixedly connected to the first clamp seat 4, the other end of the connecting rod 6 passes through the movable seat 3 and is fixedly connected to the connecting plate 7, the upper end of the connecting plate 7 is fixedly connected to the L-shaped push plate 13, and the third spring 15 is sleeved on the outer surface of the connecting rod 6.

[0024] Furthermore, the length of the guide rod 8 is greater than that of the connecting rod 6 , and when the first clamping seat 4 moves to contact with the moving seat 3 , the wedge-shaped top block 12 and the limiting rod 14 are lifted up.

[0025] In this embodiment, by setting a moving mechanism to cooperate with the second clamp seat 9, the horizontal distance between the second clamp seat 9 and the first clamp seat 4 can be matched with the difference in radial length of the speakers at different heights. Specifically, since the length of the guide rod 8 is greater than the connecting rod 6, when the electric push rod 2 is extended, the second clamp seat 9 at one end of the guide rod 8 first contacts the side wall of the basin frame. At this time, the electric push rod 2 continues to extend until it drives the first clamp seat 4 to contact the basin frame. During this process, the guide rod 8 moves along the groove body 16, and the second clamp seat 9 approaches the moving seat 3. The first spring 5 is compressed. The compressed first spring 5 generates a reaction force on the second clamp seat 9, so that the second clamp seat 9 generates a clamping force on the basin frame, thereby ensuring the stability of the top of the basin frame.

[0026] In addition, by setting a horizontal displacement mechanism in cooperation with the driving mechanism, when the first clamping seat 4 contacts the basin rack and the electric push rod 2 continues to extend, the first clamping seat 4 and the movable seat 3 move relative to each other until the first clamping seat 4 contacts the movable seat 3. At this time, the L-shaped push plate 13 connected to the first clamping seat 4 through the connecting rod 6 and the connecting plate 7 also moves relative to the movable seat 3. The L-shaped push plate 13 moves along the inclined surface of the wedge-shaped top block 12 and lifts the wedge-shaped top block 12 and the limit rod 14, so that the limit rod 14 is against the guide rod 8, thereby preventing the guide rod 8 from moving and improving the stability of the second clamping seat 9 when clamping the basin rack.

[0027] In this embodiment, after the speaker is assembled, the electric push rod 2 is driven to move back, and the first spring 5, the second spring 10, and the third spring 15 are all reset, driving the first clamping seat 4, the second clamping seat 9, the wedge-shaped top block 12 and other mechanisms to reset.
