Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-5 As shown, a drilling device for a bumper mounting bracket in this embodiment includes a fixed base 1 and a rotating base 2. The rotating base 2 is vertically arranged and rotatably connected to the fixed base 1 via a rotating shaft 6. The outer side of the rotating base 2 is provided with a plurality of positioning pins 3, a clamping device 4, and a locking device 5 for locking the rotating base 2 to the fixed base 1. The locking device 5 includes a locking screw, which is threadedly connected to the rotating base 2. The fixed base 1 is provided with at least two first connecting holes 8, and the end of the locking screw cooperates with the first connecting holes 8.

[0023] In use, with the side bracket 72 and mounting plate of the bumper mounting bracket 7 facing outwards, the bumper mounting bracket 7 is positioned by the connection hole between the positioning pin 3 and the bracket body 71. The bumper mounting bracket 7 is then fixed to the side of the rotating seat 2 by the clamping device 4 and suspended from the side of the rotating seat 2, thus fixing the bumper mounting bracket 7. When it is necessary to process the connection hole of the first connecting frame, the rotating seat 2 is rotated so that the first connecting frame is positioned above the casting, and the end of the locking screw is inserted into the first connecting hole 8, so that the locking screw engages with the first connecting hole 8 on the fixed seat 1, thereby fixing the rotating seat. 2. The rotating seat 2 is fixed to the fixed seat 1 to prevent the rotating seat 2 from rotating. The drilling machine or drilling robot processes the connecting hole of the first connecting bracket of the bumper mounting bracket 7. When it is necessary to process the connecting hole of the side bracket 72, the rotating seat 2 is rotated so that one side of the side bracket 72 is above the casting, and the end of the locking screw is inserted into another first connecting hole 8. The rotating seat 2 is fixed to the fixed seat 1 by the locking screw cooperating with the first connecting hole 8 on the fixed seat 1 to prevent the rotating seat 2 from rotating. The drilling machine or drilling robot processes the connecting hole of the side bracket 72 of the bumper mounting bracket 7.

[0024] Multiple first connecting holes 8 are located on the same circumference with the rotating shaft 6 as the center. After the rotating seat 2 rotates along the rotating shaft 6 to different angles, the locking screw on the rotating seat 2 can cooperate with multiple first connecting holes 8 on the fixed seat 1, thereby fixing the rotating seat 2 to the fixed seat 1 and preventing the rotating seat 2 from rotating.

[0025] The clamping device 4 includes a first screw 41 and a locking nut 42. The locking nut 42 is threadedly connected to the first screw 41. In use, the first screw 41 passes through a connecting hole in the middle of the support body 71 of the bumper mounting bracket 7. The first screw 41 can position the bumper mounting bracket 7 on the one hand, and after cooperating with the locking nut 42, it is convenient to lock and fix the bumper mounting bracket 7.

[0026] The side of the clamping device 4 is provided with a clamping block 9. After the bumper mounting bracket 7 is fixed to the side of the rotating seat 2, the clamping block 9 abuts against the side of the support body 71 of the bumper mounting bracket 7. Through the cooperation of the clamping block 9, the positioning column 3 and the clamping device 4, the bumper mounting bracket 7 is firmly fixed to the side of the rotating seat 2.

[0027] The locking device 5 is correspondingly arranged with the connecting hole in the middle of the support body 71 of the bumper mounting bracket 7, near the side bracket 72; there are at least two positioning pins 3, which are correspondingly arranged with the end connecting holes of the bumper mounting bracket 7. The positioning pins 3 and the first screw 41 are used to position and fix the end of the support body 71, and the first screw 41 and the locking nut 42 are used to fix the end of the bumper mounting bracket 7 near the side bracket 72 and the first connecting frame, which helps to ensure the machining accuracy of the connecting holes of the side bracket 72 and the first connecting frame.

[0028] The rotating seat 2 is provided with two sets of positioning posts 3 and clamping devices 4 on its side. The two sets of positioning posts 3 and clamping devices 4 are located on both sides of the rotating shaft 6. The same rotating seat 2 can realize the processing of bumper mounting brackets 7 that are symmetrical on the left and right.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
