DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a flange processing and pressing tool, such as Figure 1-Figure 5 As shown, a flange processing and clamping tool comprises a workbench 1 and a supporting leg 2; a limiting platform 3 is installed on the top of the workbench 1, a flange 4 is arranged inside the limiting platform 3, auxiliary structures 6 are arranged at both ends inside the limiting platform 3, and a supporting leg 2 is arranged at the bottom end of the workbench 1; a clamping structure 5 is arranged inside the workbench 1.

[0022] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the clamping structure 5 includes a servo motor 501, a connecting frame 502, a screw 503, a connecting plate 504, a rubber pad 505, a bidirectional threaded shaft 506 and a screw sleeve 507. The bidirectional threaded shaft 506 is arranged inside the workbench 1, and the outer side of the bidirectional threaded shaft 506 is provided with a screw sleeve 507. The top of the screw sleeve 507 is provided with a connecting frame 502, one side of the connecting frame 502 is provided with a connecting plate 504, the interior of the connecting plate 504 is provided with a screw 503, and the bottom end of the screw 503 is provided with a rubber pad 505. The servo motor 501 is arranged on one side of the workbench 1, the outer side of the bidirectional threaded shaft 506 is provided with an external thread, the inner side of the screw sleeve 507 is provided with an internal thread, and a threaded connection is formed between the bidirectional threaded shaft 506 and the screw sleeve 507. Two groups of rubber pads 505 are provided, and the two groups of rubber pads 505 are symmetrically distributed at the top of the workbench 1.

[0023] Specifically, in this embodiment: before processing the flange 4, the flange 4 is placed inside the limit platform 3. At this time, the use of the limit platform 3 can limit the flange 4 to prevent it from moving around. After the flange 4 is placed, the servo motor 501 is started. After the servo motor 501 is started, the connecting frame 502 is driven to move to one side through the cooperation of the bidirectional threaded shaft 506 and the screw sleeve 507. When the rubber pad 505 moves to one side of the top of the flange 4, it stops moving. At this time, the screw rod 503 is rotated. As the screw rod 503 and the connecting plate 504 rotate, the rubber pad 505 is pushed downward to press against one side of the top of the flange 4, and the flange 4 is pressed so that it will not move around during processing, thereby completing the pressing work.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 5As shown: the auxiliary structure 6 includes a rotating rod 601, a screw groove 602, a movable plate 603, a movable groove 604, a through groove 605 and a connecting rod 606. The movable groove 604 is opened at both ends inside the limiting platform 3. The movable groove 604 is provided with a connecting rod 606. The outer side of the connecting rod 606 is provided with a movable plate 603. The movable plate 603 is provided with a through groove 605 inside. The screw groove 602 is opened at the top of the movable groove 604 at both ends inside the limiting platform 3. The screw groove 602 is provided with a rotating rod 601. The connecting rod 606 is inserted into the through groove 605. The connecting rod 606 and the movable plate 603 are movably connected. The rotating rod 601 is inserted into the screw groove 602. The rotating rod 601 and the screw groove 602 are threadedly connected.

[0025] Specifically, in this embodiment, after the processing is completed, the rotating rod 601 is rotated. As the rotating rod 601 and the screw groove 602 rotate, the bottom end of the rotating rod 601 will move downward, thereby pushing one end of the movable plate 603 to move downward. When one end of the movable plate 603 moves downward, the other end of the movable plate 603 will move upward under the action of the connecting rod 606, thereby lifting one end of the flange 4 upward, so that one end of the flange 4 is pushed out from the inside of the limit table 3, making it more convenient to take the processed flange 4.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
