[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1 to 6 Example 1: This utility model proposes a straightening fixture for the left and right rear wheel supports, including: a straightening platform 1 and a fixture assembly, the fixture assembly being composed of a straightening mechanism 2 and a rotating mechanism 3; The straightening mechanism 2 consists of a support frame 201, a straightening pressure block 202, and a straightening hydraulic rod 203. The support frame 201 is fixedly installed on the top of the straightening platform 1, and the straightening pressure block 202 is inserted into the top of the straightening platform 1. The straightening hydraulic rod 203 is fixedly installed on the top of the straightening platform 1, and the top of the straightening hydraulic rod 203 is fixedly installed on the bottom of the straightening pressure block 202. The rotating mechanism 3 includes a mounting base 301, a bracket positioning plate 302, a linkage frame 304, a locking block 305, and a release push rod 306. The mounting base 301 is fixedly installed on the top of the straightening platform 1, and the bracket positioning plate 302 is rotatably connected to the inside of the mounting base 301. The linkage frame 304 is inserted into the outside of the bracket positioning plate 302. The locking block 305 is inserted into the inside of the bracket positioning plate 302 and is rotatably connected to the side of the linkage frame 304. The release push rod 306 is fixedly installed on the side of the mounting base 301, and the push rod of the release push rod 306 passes through the rotating shaft of the mounting base 301 and the bracket positioning plate 302. One end of the push rod of the release push rod 306 is rotatably connected to the inside of the linkage frame 304.

[0023] The locking block 305 is L-shaped. During use, the positioning hole at one end of the rear wheel bracket can be inserted into the outside of the positioning post 3021 for positioning. The locking block 305 presses and fixes the edge of the rear wheel bracket, so that the rear wheel bracket will not shift during the straightening process, ensuring the accuracy and efficiency of the straightening operation. The part of the rear wheel bracket that needs to be straightened is located at the top of the support frame 201. The straightening hydraulic rod 203 can drive the straightening block 202 to move down, thereby performing pressure straightening operation on the part of the rear wheel bracket that needs to be straightened. It is convenient and flexible to use.

[0024] The rotating mechanism 3 also includes a drive motor 303, which is connected to the rotating shaft of the bracket positioning disk 302 via a worm gear transmission. In use, the rotating mechanism 3 can drive the rear wheel bracket to rotate, thereby achieving straightening operations on the rear wheel bracket rod in multiple directions without disassembling the rear wheel bracket. When the drive motor 303 rotates, it can drive the bracket positioning disk 302 to rotate via the worm gear. The bracket positioning disk 302 has a positioning post 3021 on its side. The rear wheel bracket is inserted into the outside of the positioning post 3021 through the positioning hole, and the rod of the rear wheel bracket is placed on the top of the support frame 201. When the bracket positioning disk 302 rotates, it can drive the bracket to rotate via the positioning post 3021. The rear wheel bracket is firmly fixed to the side of the bracket positioning disk 302 by the locking block 305, which can ensure the stability and accuracy of the rotation of the rear wheel bracket.

[0025] The bracket positioning plate 302 has a release protrusion 3022 inside, and a control groove is provided on the outside of the locking block 305. The release protrusion 3022 is inserted into the control groove. The control groove consists of a spiral clearance groove 3052 and a straight release groove 3053, with one end of the clearance groove 3052 connected to one end of the release groove 3053. In use, the rotating mechanism 3 has the function of quickly installing and removing the rear wheel bracket, which can be achieved by controlling the extension and retraction of the release push rod 306. When the release push rod 306 is in the retracted state, the release protrusion 3022 is located inside the release groove 3053, so the block of the locking block 305 will invade the space on the side of the bracket positioning plate 302, and with the retraction of the release push rod 306, it will press on the bracket to fix and position it. For an extended period, the release push rod 306 can drive the linkage frame 304 to move forward. When the linkage frame 304 moves, it can drive the locking block 305 to move synchronously. When the locking block 305 moves, the release protrusion 3022 will first move inside the release groove 3053, without hindering the movement of the locking block 305 and the bracket away from each other. As the release push rod 306 extends, the release protrusion 3022 will enter the interior of the clearance groove 3052. Under the guiding action of the release protrusion 3022 on the clearance groove 3052, the locking block 305 will rotate. After the locking block 305 rotates, the lifting part no longer intrudes into the space inside the side of the bracket positioning plate 302 (effective for fixing the bracket). At this time, the rear wheel bracket can be freely picked up, placed, installed, and disassembled on the side of the bracket positioning plate 302, simplifying the installation and disassembly process and improving work efficiency.

[0026] The working principle of this embodiment is as follows: The positioning hole at one end of the rear wheel bracket can be inserted into the outside of the positioning post 3021 for positioning, and the edge of the rear wheel bracket is pressed and fixed by the locking block 305, so that the rear wheel bracket will not shift during the straightening process, ensuring the accuracy and efficiency of the straightening operation. The part of the rear wheel bracket that needs to be straightened is located at the top of the support frame 201. The straightening hydraulic rod 203 can drive the straightening block 202 to move down, thereby performing a pressure straightening operation on the part of the rear wheel bracket that needs to be straightened. The rotating mechanism 3 can drive... The rear wheel bracket rotates, allowing for straightening of the rear wheel bracket rod in multiple directions without disassembling or assembling it. When the drive motor 303 rotates, it drives the bracket positioning plate 302 to rotate via a worm gear. The rotating plate 302, in turn, drives the bracket to rotate via the positioning pin 3021. The rear wheel bracket is firmly fixed to the side of the bracket positioning plate 302 by the locking block 305. The rotating mechanism 3 has a function for quick installation and removal of the rear wheel bracket, which can be achieved by controlling the extension and retraction of the release push rod 306. When lever 306 is in the retracted state, the release protrusion 3022 is located inside the release groove 3053, causing the locking block 305 to intrude into the space on the side of the bracket positioning plate 302. As the release lever 306 retracts, it presses against the bracket to fix and position it. When the release lever 306 extends, it drives the linkage frame 304 forward. The linkage frame 304, in turn, drives the locking block 305 to move synchronously. When the locking block 305 moves, the release protrusion 3022 first... The internal movement of the clamping groove 3053 will not hinder the movement of the locking block 305 and the bracket away from each other. As the release push rod 306 extends, the release protrusion 3022 will enter the interior of the clearance groove 3052. Under the guiding action of the release protrusion 3022 on the clearance groove 3052, the locking block 305 will rotate. After the locking block 305 rotates, the lifting part no longer intrudes into the space inside the side of the bracket positioning plate 302 (effective for fixing the bracket). At this time, the rear wheel bracket can be freely removed, placed, installed, and disassembled on the side of the bracket positioning plate 302.
