[0002] For example, in the flange clamp with automatic eccentric displacement structure disclosed on the Chinese Patent website (application number: 202222339825.9), the position of the flange clamp is adjusted by longitudinal and transverse mechanisms. During this process, a motor and a cylinder are required to cooperate, which is not convenient. Multiple mechanisms are required to complete the adjustment, making it cumbersome to operate. Furthermore, the presence of multiple operating mechanisms makes it prone to errors. Utility Model Content

[0003] To address the technical problems of inconvenient adjustment and error-proneness of existing flange adjustment mechanisms, this utility model proposes a flange clamp with an automatic eccentric displacement structure.

[0004] This utility model proposes a flange clamp with an automatic eccentric displacement structure, including a mounting base.

The drive motors control the rotating rods and driving gears to rotate, the driving gears drive the driven gears to rotate, the driven gears drive the threaded rods to rotate, and the threaded rods control the horizontal movement of the movable clamping plates.

[0005] Preferably, both drive motors are fixedly installed inside the mounting base, the rotating rod is fixedly installed on the rotating shaft of the drive motor, the drive gear is fixedly installed on the outer surface of the rotating rod, and the two drive motors are horizontally symmetrically distributed with the axis of the mounting base as the center of symmetry.

[0006] With the above technical solution, when the drive motor starts, the rotating shaft drives the rotating rod to rotate, and the rotating rod drives the drive gear to rotate.

[0008] Through the above technical solution, the driving gear drives the driven gear to rotate, causing the threaded rod to rotate, and the limit bearing ensures that the threaded rod rotates stably.

[0009] Preferably, the mounting base has a slot inside, and the two movable plates are slidably inserted into the slot. The inside of the movable plate is threadedly connected to the outer surface of the threaded rod, and an arc plate is fixedly installed on the upper surface of the movable plate.

[0010] Through the above technical solution, the movable card plate moves horizontally within the card slot, causing the arc plate to move against the upper surface of the mounting base.

[0011] Preferably, a flange is placed on the upper surface of the mounting base, the flange is sandwiched between two arc plates, and a control switch and a battery are fixedly installed on the left side of the mounting base, the control switch is located above the battery, and both the control switch and the battery are electrically connected to the drive motor through wires.

[0012] The above technical solution controls the start and stop of the drive motor with a control switch, the battery provides power to the drive motor, and the two arc plates clamp the flange.

[0014] Through the above technical solution, the connecting frame can be connected to the relevant machine through the mounting hole. The horizontal position of the adjusting rod can be adjusted by rotating it. The stop switch will control the drive motor to stop when it is pressed by the adjusting rod. A round hole is opened in the moving plate on the right. The adjusting rod is placed in the round hole and rotates, so that the rotation of the adjusting rod will not affect the moving plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting up a control device, when clamping the flange, the adjusting rod is first rotated to adjust its horizontal position. Then, the left drive motor is started to control the rotating rod to rotate. The rotating rod drives the drive gear to rotate, which in turn drives the driven gear to rotate, causing the threaded rod to rotate. The threaded rod controls the movement of the moving clamping plate, which in turn moves the arc plate until the stop switch on the moving clamping plate touches the left end of the adjusting rod and is pressed, stopping the left drive motor and thus controlling the position of the left arc plate. Then, the right drive motor is started to control the movement of the right arc plate, allowing the two arc plates to clamp the flange. The position of the left arc plate is adjusted by controlling the position of the adjusting rod, thereby adjusting the position of the flange. The operation process is simple and error-free, achieving the effect of convenient flange position adjustment and low error rate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A flange clamp with an automatic eccentric displacement structure includes a mounting base 1. To facilitate clamping of the flange 13, a control device is provided inside the mounting base 1. The control device includes two drive motors 2, two rotating rods 3, two driving gears 4, two driven gears 5, two threaded rods 6, and two movable clamping plates 7. The drive motors 2 control the rotating rods 3 and driving gears 4 to rotate. The driving gears 4 drive the driven gears 5 to rotate. The driven gears 5 drive the threaded rods 6 to rotate. The threaded rods 6 control the movable clamping plates 7 to move horizontally.

[0023] To facilitate the control of the drive gear 4 by the drive motor 2, both drive motors 2 are fixedly installed inside the mounting base 1. The rotating rod 3 is fixedly installed on the rotating shaft of the drive motor 2, and the drive gear 4 is fixedly installed on the outer surface of the rotating rod 3. The two drive motors 2 are horizontally symmetrically distributed with the axis of the mounting base 1 as the center of symmetry. When the drive motor 2 starts, the rotating shaft drives the rotating rod 3 to rotate, and the rotating rod 3 drives the drive gear 4 to rotate.

[0024] To facilitate stable rotation of the threaded rod 6, a limit bearing 11 is fixedly installed inside the mounting base 1. The threaded rod 6 is fixedly installed on the inner shaft of the limit bearing 11. The driven gear 5 is fixedly installed on the outer surface of the threaded rod 6, and the outer surface of the driven gear 5 meshes with the outer surface of the driving gear 4. A connecting rod 61 is fixedly installed on the outer surface of the threaded rod 6, and the outer surface of the connecting rod 61 is fixedly connected to the inner side of the inner shaft of the limit bearing 11. The driving gear 4 drives the driven gear 5 to rotate, causing the threaded rod 6 to rotate. The limit bearing 11 ensures that the threaded rod 6 maintains stable rotation.

[0025] To facilitate the control of the arc plate 71 moving against the upper surface of the mounting base 1, the mounting base 1 has a slot 12 inside. Both movable plates 7 are slidably inserted into the slot 12. The inside of the movable plates 7 is threadedly connected to the outer surface of the threaded rod 6. The arc plate 71 is fixedly installed on the upper surface of the movable plates 7. The movable plates 7 move horizontally in the slot 12, causing the arc plate 71 to move against the upper surface of the mounting base 1.

[0026] To facilitate the clamping of the flange 13 by the two arc plates 71, the flange 13 is placed on the upper surface of the mounting base 1. The flange 13 is clamped between the two arc plates 71. The control switch 14 and the battery 15 are fixedly installed on the left side of the mounting base 1. The control switch 14 is located above the battery 15. Both the control switch 14 and the battery 15 are electrically connected to the drive motor 2 through wires. The control switch 14 controls the start and stop of the drive motor 2, and the battery 15 provides power to the drive motor 2. The two arc plates 71 clamp the flange 13.

[0027] To facilitate automatic control of the drive motor 2 to stop, a connecting bracket 16 is fixedly installed on the lower surface of the mounting base 1. The connecting bracket 16 has a mounting hole 17 inside. An adjusting rod 18 is threadedly connected inside the mounting base 1. A stop switch 72 is fixedly installed inside the movable plate 7 on the left side. The stop switch 72 is electrically connected to the drive motor 2 on the left side through a wire. The connecting bracket 16 can be connected to the relevant machine through the mounting hole 17. The horizontal position of the adjusting rod 18 is adjusted by rotating it. When the stop switch 72 is pressed by the adjusting rod 18, it will control the drive motor 2 to stop.

[0028] By setting up a control device, when clamping the flange 13, the adjusting rod 18 is rotated first to adjust its horizontal position. Then, the left drive motor 2 is started to control the rotating rod 3 to rotate. The rotating rod 3 drives the drive gear 4 to rotate, which in turn drives the driven gear 5 to rotate, causing the threaded rod 6 to rotate. The threaded rod 6 controls the movement of the moving clamping plate 7, which in turn moves the arc plate 71 until the stop switch 72 on the moving clamping plate 7 touches the left end of the adjusting rod 18 and is squeezed, thus stopping the left drive motor 2 and controlling the position of the left arc plate 71. Then, the right drive motor 2 is started to control the movement of the right arc plate 71, allowing the two arc plates 71 to clamp the flange 13. The position of the left arc plate 71 is adjusted by controlling the position of the adjusting rod 18, thereby adjusting the position of the flange 13. The operation process is simple and error-free, achieving the effect of convenient adjustment of the flange 13 position and minimizing errors.

[0029] Working principle: When clamping flange 13, first rotate adjusting rod 18 to adjust its horizontal position. Then, start the left drive motor 2 to control rotating rod 3 to rotate. Rotating rod 3 drives drive gear 4 to rotate, which in turn drives driven gear 5 to rotate, causing threaded rod 6 to rotate. Threaded rod 6 controls moving clamping plate 7 to move, which in turn moves arc plate 71 until the stop switch 72 on moving clamping plate 7 touches the left end of adjusting rod 18 and is pressed, stopping the left drive motor 2 and controlling the position of the left arc plate 71. Then, start the right drive motor 2 to control the movement of the right arc plate 71, allowing the two arc plates 71 to clamp flange 13. The position of the left arc plate 71 is adjusted by controlling the position of adjusting rod 18, thereby adjusting the position of flange 13. The operation process is simple and error-free.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
