[0037] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0038] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0039] like Figures 2 to 5 As shown, the first exemplary embodiment of the present application provides a rearview mirror bracket positioning tool, which includes a tool support 1, a bracket fixing structure 2 and a bracket limiting structure 3, wherein the tool support 1 is extended in the up and down directions and is used to place the rearview mirror bracket 6, the bracket fixing structure 2 is arranged in the tool support 1 and is used to fix the rearview mirror bracket 6, and the bracket limiting structure 3 is arranged in the tool support 1 and is used to limit the pipe section 601 to be pressed of the rearview mirror bracket 6 to be parallel to the mold pressing surface of the bending machine.

[0040] Therefore, when the rearview mirror bracket 6 is subjected to the pressing process, the bracket fixing structure 2 can be used to fix the rearview mirror bracket 6 on the tooling support 1, so that the entire rearview mirror bracket 6 is stable and does not swing. The key is that when the rearview mirror bracket 6 is placed on the tooling support 1, the pipe section 601 to be pressed of the rearview mirror bracket 6 can be placed on the bracket limiting structure 3, so that the pipe section 601 to be pressed is parallel to the mold pressing surface of the bending machine. In this way, when the bending machine is used to press the pipe section 601 to be pressed, the flatness of the pressed pressing mounting part is extremely high, which effectively ensures the product quality of the rearview mirror bracket, thereby meeting the requirements of accurate installation of the rearview mirror bracket 6.

[0041] Since the pipe section 601 to be pressed of the rearview mirror bracket 6 is arranged at the end of the main pipe section 602, in an optional or preferred embodiment, the bracket limiting structure 3 is arranged on the top of the tool support 1, and the bracket fixing structure 2 is arranged in the middle of the tool support 1 and is used to fix the main pipe section 602 of the rearview mirror bracket 6. In this way, when placing the rearview mirror bracket 6, the pipe section 601 to be pressed can be placed on the bracket limiting structure 3 first, so as to facilitate adjusting the placement angle of the rearview mirror bracket 6 so that the pipe section 601 to be pressed is parallel to the mold pressing surface of the bending machine. Then, the bracket fixing structure 2 is used to fix the main pipe section 602 in the middle of the tool support 1, thereby achieving rapid positioning and installation of the rearview mirror bracket 6.

[0042] Furthermore, if Figure 2 and Figure 3 As shown, the tool support 1 includes a base 101 and an extension bracket 102, wherein the bottom end of the extension bracket 102 is connected to the top end of the base 101, the bracket limiting structure 3 is arranged on the top of the extension bracket 102, and the bracket fixing structure 2 is arranged on the bottom of the extension bracket 102. In this embodiment, by using the base 101 and the extension bracket 102 in combination, the overall height of the tool support 1 can be effectively increased, so that the tool support 1 can support the pipe section 601 to be pressed of the rearview mirror bracket 6 to be at the same height as the mold pressing surface of the bending machine, so as to facilitate the bending machine to perform rapid pressing and improve the bracket production efficiency. In this embodiment, the base 101 and the extension bracket 102 can be fixedly connected by welding. The base 101 and the extension bracket 102 can both be formed into a frame structure with high stability. When the tool support 1 is in use, the base 101 can be placed stably on the ground.

[0043] In addition, considering that the existing rearview mirror bracket 6 is generally provided with multiple bending sections, Figure 1 The main pipe section 602 is composed of a plurality of bending sections, and the pipe section 601 to be pressed is located at the end of the last bending section. In order to adapt to the structure of the rearview mirror bracket 6, the pipe section 601 to be pressed is effectively limited, such as Figure 2 and Figure 3As shown, the extension bracket 102 includes a first vertical extension section 1021, a second vertical extension section 1022, and a transverse extension section 1023. The bottom end of the first vertical extension section 1021 is connected to the top of the base 101, and the ends of the transverse extension section 1023 are respectively connected to the top of the first vertical extension section 1021 and the bottom of the second vertical extension section 1022. A bracket retaining structure 3 is disposed on the top of the second vertical extension section 1022, and a bracket fixing structure 2 is disposed within the first vertical extension section 1021. Thus, the extension bracket 102 as a whole forms a bending structure adapted to fit within the rearview mirror bracket 6. When the bracket fixing structure 2 secures the main tube section 602, the tube section 601 to be pressed, located at the end of the main tube section 602, can be placed on the bracket retaining structure 3 parallel to the pressing surface of the press brake mold. In this embodiment, the first vertical extension section 1021, the second vertical extension section 1022, and the transverse extension section 1023 are fixedly connected by welding.

[0044] In an optional or preferred embodiment, Figure 4 As shown, the support retaining structure 3 includes a retaining groove 301 for supporting the pipe segment 601 to be pressed. The central axis of the retaining groove 301 can be arranged parallel to the pressing surface of the mold, and the cross-sectional profile of the retaining groove 301 matches the cross-sectional profile of the pipe segment 601 to be pressed. For example, when the pipe segment 601 to be pressed is a round tube as shown in the figure, the cross-sectional profile of the retaining groove 301 is an arc, and the radius of the arc is consistent with the radius of the pipe segment 601 to be pressed. When the pipe segment 601 to be pressed is a square tube, the cross-sectional profile of the retaining groove 301 is a square, and the length of the square is consistent with the thickness of the pipe segment 601 to be pressed. It can be seen that the structure of the retaining groove 301 in this example matches the tube shape of the pipe segment 601 to be pressed. When the pipe segment 601 to be pressed is placed in the retaining groove 301, the retaining groove 301 can effectively retain the pipe segment 601 to be pressed, so that the pipe segment 601 to be pressed can remain parallel to the pressing surface of the mold.

[0045] In an optional or preferred embodiment, the bracket fixing structure 2 includes a clamping assembly for clamping the main tube section 602 of the rearview mirror bracket 6. Specifically, the clamping assembly can be an elastic pre-tightening clamping claw, or a clamping member such as Figure 5As shown, the clamping assembly includes a stopper 201 and a fastening bolt 202. The stopper 201 is formed with a pipe passage hole for the main pipe section 602 to pass through, as well as a screw hole connecting the pipe passage hole. The fastening bolt 202 is detachably inserted into the screw hole. Thus, when securing the rearview mirror bracket 6, the main pipe section 602 can be first inserted into the pipe passage hole of the stopper 201. The pipe section 601 to be pressed is then adjusted parallel to the pressing surface of the mold. The fastening bolt 202 is then inserted into the screw hole of the stopper 201 and tightened until the stud of the fastening bolt 202 and the stopper 201 jointly clamp the main pipe section 602, thereby securing the rearview mirror bracket 6. Furthermore, when fine-tuning or disassembling the rearview mirror bracket 6 is necessary, simply loosen the fastening bolt 202, making it quick and convenient. It should be supplemented that the limit block 201 can be fixed in the tooling support 1 by welding or screwing, which is not limited in this application.

[0046] In an optional or preferred embodiment, Figure 2 As shown, there are multiple bracket fixing structures 2 and bracket limiting structures 3, and the multiple bracket fixing structures 2 and the multiple bracket limiting structures 3 are arranged in sequence along the left and right directions. In this way, when positioning the rearview mirror bracket 6, the actual position of the bending machine can be viewed to select a suitable set of bracket fixing structures 2 and bracket limiting structures 3 to fix the rearview mirror bracket 6 on the tooling support 1, thereby improving operational flexibility.

[0047] Furthermore, considering that the overall height or length of the rearview mirror bracket 6 is relatively large, as shown in FIG. Figure 2 As shown, there are multiple bracket fixing structures 2, and the multiple bracket fixing structures 2 are arranged in sequence along the up and down directions, so that the rearview mirror bracket 6 can be fixed at different heights by multiple bracket fixing structures 2 at the same time, which greatly enhances the stability of the rearview mirror bracket 6.

[0048] The second exemplary embodiment of the present application provides a rearview mirror bracket pressing system, which includes a bending machine and the aforementioned rearview mirror bracket positioning tooling. The bending machine includes an upper mold 4 and a lower mold 5 positioned in a vertically opposed manner. The bottom surface of the upper mold 4 is provided with an upper mold pressing surface, and the top surface of the lower mold 5 is provided with a lower mold pressing surface that matches the upper mold pressing surface. The bracket support surface of the bracket limiting structure 3 of the aforementioned rearview mirror bracket positioning tooling is arranged at the same height as the lower mold pressing surface, so that the pipe section 601 to be pressed of the rearview mirror bracket 6 can be placed on the bracket support surface and the lower mold pressing surface at the same time, facilitating the upper mold 4 to stamp the pipe section 601 to be pressed, and ensuring that the pipe section 601 to be pressed does not deviate or deform, resulting in a higher quality finished product. In addition, the rearview mirror bracket pressing system of this exemplary embodiment also has all the technical effects brought about by the aforementioned rearview mirror bracket positioning tooling, which will not be repeated here.
