[0022] 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.

[0023] Please see Figure 1-4An embodiment of this utility model provides an auxiliary tool for installing an elliptical metal ring pad, including a base plate 1, a lifting drive box 4 above the base plate 1, a translation drive box 5 below the lifting drive box 4, a fixing component 3 on one side of the lifting drive box 4, the fixing component 3 including a bidirectional cylinder 301 and a back block 302, the bidirectional cylinder 301 being fixedly installed on one side of the back block 302, the bidirectional cylinder 301 being externally connected to a pumping device, lifting blocks 6 being symmetrically arranged above and below the bidirectional cylinder 301, the piston rod end of the bidirectional cylinder 301 being fixedly connected to the lifting block 6, a fixing arc block 7 being fixedly installed at the end of the lifting block 6 away from the bidirectional cylinder 301, and a mounting seat 2 being symmetrically fixedly installed on the front and rear ends of one side of the fixing component 3 above the base plate 1, the mounting seat 2 having a mounting groove inside.

[0024] The fixing component 3 uses a two-way cylinder 301 to drive the lifting block 6 and the fixing arc block 7 to open, which can stably clamp the elliptical metal ring gasket, avoid the risk of slippage, and improve installation safety. At the same time, the setting of the lifting drive box 4 and the translation drive box 5 facilitates the automated driving of the elliptical metal ring gasket to lift and move horizontally. This not only greatly reduces the labor intensity of workers, but also improves installation efficiency, ensuring that the elliptical metal ring gasket is completely fitted to the flange sealing surface, and avoiding the problem of poor sealing caused by fatigue or error in traditional manual operation.

[0025] Please see Figure 3 The lifting drive box 4 is equipped with a screw drive mechanism, which includes a ball screw 9, a sliding block 10, and a transmission plate 11. The ball screw 9 is rotatably connected to the lifting drive box 4. The drive motor of the ball screw 9 is located on the top of the lifting drive box 4. The drive motor is a servo motor. The sliding block 10 is slidably installed on the outside of the ball screw 9 through a ball nut. The transmission plate 11 is fixedly installed on one side of the sliding block 10. The end of the transmission plate 11 away from the sliding block 10 is fixedly connected to the back block 302.

[0026] The screw drive mechanism inside the lifting drive box 4, through the cooperation of the ball screw 9 and the sliding block 10, can realize the lifting movement, ensuring the lifting and lowering movement of the elliptical metal ring pad during installation. By controlling the rotation of the ball screw 9 by the drive motor, the lifting and lowering of the elliptical metal ring pad can be completed, reducing the difficulty of operation and improving work efficiency.

[0027] Please see Figure 3 Inside the lifting drive box 4, a guide rod 12 is fixedly installed along one side of the ball screw 9, and the guide rod 12 slides through the transmission plate 11.

[0028] The guide rod 12, used in conjunction with the ball screw 9, provides additional support and guidance for the transmission plate 11, preventing skewing or shaking during lifting and ensuring the smoothness and precision of the lifting motion. At the same time, the addition of the guide rod 12 enhances the overall rigidity of the lifting drive box 4, enabling it to withstand greater loads. Furthermore, the guide rod 12 can share the force of the ball screw 9, reducing its wear and increasing its practicality.

[0029] Please see Figure 1 and Figure 4 The translation drive box 5 is equipped with a second screw drive mechanism, which includes a second ball screw 13, a second sliding block 14, and a second transmission plate 15. The second ball screw 13 is rotatably connected to the translation drive box 5. A drive motor for the second ball screw 13 is provided on one side of the translation drive box 5. The drive motor is a servo motor. The second sliding block 14 is slidably installed on the outside of the second ball screw 13 through a ball nut. The second transmission plate 15 is fixedly installed on the front end of the second sliding block 14. The end of the second transmission plate 15 away from the second sliding block 14 is fixedly connected to the lifting drive box 4.

[0030] The screw drive mechanism 2 inside the translation drive box 5, through the cooperation of ball screw 2 13 and sliding block 2 14, facilitates the horizontal movement of the elliptical metal ring gasket, ensuring accurate alignment with the flange sealing surface and improving installation accuracy. During use, the rotation of ball screw 2 13 is controlled by the drive motor, allowing workers to easily complete the horizontal movement of the elliptical metal ring gasket without manual adjustment, thus reducing the difficulty of operation.

[0031] Please see Figure 1 The front and rear ends of the translation drive box 5 are symmetrically provided with guide rods 16. One end of the guide rod 16 is fixedly connected to the mounting base 2, and the other end of the guide rod 16 is fixedly installed with a vertical plate 17. The lower end of the vertical plate 17 is fixedly connected to the base plate 1. The lower ends of the lifting drive box 4 are symmetrically fixedly installed with side plates 18 below the front and rear ends, and the guide rod 16 slides through the side plate 18.

[0032] The setting of guide rod 16, together with the upright plate 17 and the side plate 18, provides additional support and guidance for the translation of the lifting drive box 4, preventing skewing or shaking during horizontal movement and ensuring the smoothness and accuracy of the translation movement.

[0033] Please see Figure 2 A rubber pad 8 is fixedly installed on the outer side of the fixed arc block 7.

[0034] The rubber pad 8 increases the friction between the fixed arc block 7 and the elliptical metal ring pad, preventing the elliptical metal ring pad from slipping during clamping and improving the stability and safety of clamping. At the same time, the softness of the rubber pad 8 prevents the fixed arc block 7 from directly contacting the elliptical metal ring pad, preventing scratches or damage to the elliptical metal ring pad and increasing its practicality.

[0035] Please see Figure 1 All four corners below the base plate 1 are equipped with rotating casters.

[0036] The use of wheeled tools allows for easy movement of the tools, enabling workers to quickly switch between different installation locations and improving work efficiency.

[0037] Working principle: In use, the elliptical metal ring gasket is placed in the mounting slot of the mounting base 2 above the base plate 1. By driving the ball screw 13 to rotate, the sliding block 14 moves, which in turn drives the lifting drive box 4 and the fixing component 3 to move horizontally. This causes the double-acting cylinder 301 of the fixing component 3 to move into the interior of the elliptical metal ring gasket. Then, the double-acting cylinder 301 in the fixing component 3 drives the two lifting blocks 6 to open the fixing arc block 7 to clamp the elliptical metal ring gasket, making the elliptical metal ring gasket stable and preventing it from slipping. Next, the ball screw 9 is driven to rotate, which drives the sliding block 10 to move up and down, which in turn drives the elliptical metal ring gasket to move up and down, so that the elliptical metal ring gasket is aligned with the flange sealing surface to be installed. Then, the ball screw 13 is driven to rotate, moving the elliptical metal ring gasket to the flange sealing surface position, and the installation is completed by fitting it with the sealing surface.
