[0004] The device of this patent starts the driving cylinder, which drives the upper module to move downward, and the columnar part is inserted into the through hole of the annular bushing, and the upper module and the workpiece to be processed jointly extrude the bushing to make the bushing flanged. After the downward pressure time of the upper module reaches the preset time, the driving cylinder drives the upper module to move upward to complete the flanging process of a bushing. Since the driving cylinder is used for flanging processing, high production efficiency is achieved. Since the driving cylinder is used, the downward pressure is uniform, thereby improving the flanging quality. Since the flanging punch of this patent is fixed to the driving cylinder by bolts, it takes a lot of time for the staff to replace the flanging punch when it is accidentally damaged, which makes it inconvenient to meet the staff's usage needs. Utility Model Content

[0005] The utility model aims to provide a flanging device for an automobile bushing.

[0006] The technical problem solved by the utility model is that the existing equipment needs to consume a lot of time of the staff to replace the flanging punch.

[0007] The utility model can be realized by the following technical scheme: an automobile bushing flanging device comprises a fixing frame, the top end of the fixing frame inner cavity is connected with a mounting frame in a floating manner, the inner cavity of the mounting frame is connected with a hexagonal mounting plate in a rotatable manner, the outer wall of the hexagonal mounting plate is evenly provided with six flanging punches, and the bottom end of the fixing frame inner cavity is fixedly provided with a bushing placement seat matched with the flanging punches;

[0008] Each flanging punch is connected to the hexagonal mounting plate through an installation and disassembly component, which includes an insert block fixedly connected to the flanging punch. The outer wall of the hexagonal mounting plate is provided with a slot adapted to the insert block, and the hexagonal mounting plate and the insert block are fixed by a positioning pin.

[0009] A further technical improvement of the utility model is that a rotating rod is rotatably connected between the two inner side walls of the installation frame, and the outer peripheral wall of the rotating rod is fixedly connected to the inner cavity of the hexagonal installation plate.

[0010] A further technical improvement of the utility model is that one end of the rotating rod passes through the installation frame and extends to the front side of the installation frame, a rotating handle is fixedly installed on the end of the rotating rod extending to the front side of the installation frame, and the outer peripheral wall of the rotating handle is engraved with anti-slip grooves, which makes it convenient for users to rotate the rotating handle.

[0011] A further technical improvement of the utility model is that a limit assembly for limiting the arbitrary rotation of the hexagonal mounting plate is arranged on the front of the mounting frame, the limit assembly includes a fixed plate fixed to the front of the mounting frame, the inner cavity of the fixed plate passes through a sliding rod elastically slidably connected, a T-shaped limit block is fixedly installed on one end of the sliding rod away from the fixed plate, and six limit grooves are evenly arranged on the outer wall of the hexagonal mounting plate, and the limit grooves are adapted to the T-shaped limit blocks.

[0012] A further technical improvement of the utility model is that a sliding block is fixedly installed on the side wall of the installation frame, and a sliding rail for the sliding block to slide is fixedly installed on the inner wall of the fixing frame, so that the stability of the installation frame when sliding can be improved by the coordinated use of the sliding block and the sliding rail.

[0013] A further technical improvement of the utility model is that an L-shaped detection plate is fixedly installed on the side wall of the mounting frame and on one side of the slider, and a displacement sensor for detecting the downward movement distance of the L-shaped detection plate is fixedly installed on the inner wall of the fixing frame.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] When the flange punch is accidentally damaged, the damaged flange punch can be replaced. When replacing, the damaged flange punch can be selectively disassembled. When disassembling it, the corresponding positioning pin is first taken out and the plug block on the flange punch is moved away from the slot in the inner cavity of the hexagonal mounting plate to complete the disassembly of the damaged flange punch. After disassembly, the limit of the rotating rod is released. When releasing the limit, the sliding rod is first pulled to cause the extrusion spring sleeved on the outer peripheral wall of the sliding rod to undergo elastic deformation, and the T-shaped limit block fixedly connected to one end of the sliding rod is driven away from the limit groove in the inner cavity of the rotating rod through the movement of the sliding rod. At this time, the rotating handle is rotated again to make the rotating rod rotate synchronously, and the hexagonal mounting plate is driven to rotate synchronously through the rotating rod. When the next flange punch rotates to the originally damaged flange punch, the sliding rod is released again, and the rotating rod can be limited again by the restoring force of the extrusion spring, thereby facilitating the staff to quickly replace the flange punch in a short time, and thus facilitating the use needs of the staff.

[0016] 2. The utility model can facilitate the staff to install and disassemble the hexagonal mounting plate according to actual use requirements through the six flange punches on the outer wall of the hexagonal mounting plate and the detachable design of the hexagonal mounting plate, thereby facilitating the overall flexibility of the equipment and facilitating its use.

[0030] The inner cavity of the fixed frame 1 is provided with a detection mechanism for controlling the downward movement distance of the installation frame 21, and the detection mechanism includes a slider 3 fixedly connected to the side wall of the installation frame 21, and the inner wall of the fixed frame 1 is fixedly installed with a slide rail 31 for the slider 3 to slide, and the side wall of the installation frame 21 and one side of the slider 3 are fixedly installed with an L-shaped detection plate 32, and the inner wall of the fixed frame 1 is fixedly installed with a displacement sensor 33 for detecting the downward movement distance of the L-shaped detection plate 32, and the detection end of the displacement sensor 33 is toward the top of the inner wall of the L-shaped detection plate 32.

[0031] The flanging punch 213 is connected to the hexagonal mounting plate 212 through an installation and disassembly assembly, which includes an insert block 4 fixedly connected to the flanging punch 213. The outer wall of the hexagonal mounting plate 212 is provided with a slot 41 adapted to the insert block 4.
