That is, in use, the circular tube beam 1 is supported by the support table 11, and the two ends of the circular tube beam 1 are limited by the second positioning seats 13 to prevent axial displacement of the circular tube beam 1. The position of the bracket 4 on the circular tube beam 1 is positioned by the first positioning seat 12;

[0036] Wherein, a positioning structure 14 for positioning the obstacle eliminator support 3 is arranged on the side of the support table 11. The positioning structure 14 has a first positioning surface 141 that fits the side surface of the obstacle eliminator support 3 and a second positioning surface 142 that fits the bottom surface of the obstacle eliminator support 3; the position of the obstacle eliminator 3 on the circular tube beam 1 is positioned by the first positioning surface 141 and the second positioning surface 142;

[0037] The assembly device further includes a movable pressing device 15 for pressing the circular tube beam 1 onto the support table 11. In use, the circular tube beam 1 is pressed onto the support table 11 from above by the movable pressing device 15, so that the circular tube beam 1 is fixedly connected to the support table 11. Support tables 11 are fixedly connected to both sides of the substrate where the first positioning seats 12 are located.

[0038] See Figure 2 as shown:

[0039] In a preferred embodiment, a positioning groove 111 with a V-shaped structure is formed in the upper part of the support table 11. The circular tube beam 1 is supported by the positioning groove 111. A sliding groove 112 is formed on one side of the support table 11 where the positioning groove 111 is located. The sliding groove 112 is slidably connected to the movable pressing device 15, so as to adjust the first pressing position, enabling it to approach or move away from the positioning groove 111, ensuring that the movable pressing device 15 can positionally press the main body cylinder onto the positioning groove 111;

[0040] In a preferred embodiment, the movable pressing device 15 includes a slider 151 slidably connected to the sliding groove 112, a pressing plate 152 sleeved on the slider 151, and a nut for providing a pressing force to the pressing plate 152.

[0046] In a preferred embodiment, the positioning structure 14 includes a positioning plate a and a support block b fixedly connected to the substrate, and a positioning post c fixedly connected to the support table 11. The positioning post c can be a convex block or a positioning pin. The side surface of the positioning plate a and the side surface of the positioning post c are coplanar, thereby forming a first positioning surface 141. The first positioning surface 141 abuts against the side surface of the obstacle eliminator support 3. The top surface of the support block b is a second positioning surface 142, and the second positioning surface 142 abuts against the bottom surface of the obstacle eliminator support 3.

[0049] Specifically, the positioning pin includes a first positioning pin 121 and a second positioning pin 132. The first positioning seat 12 is provided with the first positioning pins 121 installed on both sides. The relative position between the first positioning pin 121 and the bracket 4 is locked by mating the first positioning pin 121 with the pin hole of the bracket 4. The second positioning seat 13 is provided with four second positioning pins 132. The relative position between the second positioning seat 13 and the device main body 10 is locked by mating the second positioning pins 132 with the pin holes at the four corner positions of the device main body 10;

[0050] See Figure 2 、 3 as shown in:

[0051] In a preferred embodiment, the second positioning seat 13 includes a seat body. The top end of the seat body is rotatably connected to a seat split body 131 through a horizontal shaft. A positioning pin is installed at the top end of the seat split body 131. During use, the seat split body 131 flips around the horizontal shaft.

[0052] In the above technical solution, for the track passenger car antenna beam assembly device provided by the present utility model, the usage method is as follows:

[0053] Refer to Figure 3 As shown, first insert the circular tube beam 1 into the circular holes of the bracket 4 and the obstacle eliminator support 3, and place it according to the approximate dimensions. Then hoist the circular tube beam 1 with the bracket 4 and the obstacle eliminator support 3 sleeved thereon above the support table 11 of the antenna beam assembly device and gently lower it.

[0054] Rotate the bracket 4 to make it fit against the first positioning seat 12 and lock and fix it with two first positioning pins 121. Then place the two obstacle eliminator supports 3 at the set positions so that their side end faces are in three-point contact with the positioning structure 14, and press and fix them with the side pressing device 16.

[0055] Then make the outer end faces of the two connecting seats 2 respectively fit against the inner end faces of the seat split body 131 of the second positioning seat 13 and lock them with the second positioning pins 132. Flip the seat split body 131 by 90°, and the inner end faces of the connecting seats 2 can be vertically fitted against the circular tube beam 1.

[0056] Push the movable pressing device 15 to slide the pressing plate 152 above the circular tube beam 1 and press and fix the circular tube beam 1. Check whether the positioning of each component is accurate. After ensuring there is no error, spot welding can be carried out to complete the antenna beam assembly process.

[0057] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
