[0025] Additionally, the term "plurality" shall mean two or more.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figure 1 、 Figure 2As shown, a mechanical seal automatic assembly tool includes a horizontal plate 1 and a vertical plate 2, wherein the horizontal plate 1 is fixedly provided with a base 3 adapted to the workpiece, and the vertical plate 2 is slidably connected with a pressure plate 4 and a mounting plate 5, and a first driving mechanism for driving the pressure plate 4 to slide up and down is fixedly provided between the pressure plate 4 and the mounting plate 5, and a second driving mechanism for driving the mounting plate 5 to slide up and down is fixedly provided between the mounting plate 5 and the horizontal plate 1. Specifically, when assembling the mechanical seal, the dynamic ring is aligned with the dynamic ring seat and then placed on the base 3, and then the first driving mechanism and the pressure plate 4 are roughly adjusted downward to a position close to the top of the mechanical seal workpiece to be assembled by the second driving mechanism, and then the pressure plate 4 is slowly driven downward by the first driving mechanism, and the pressure plate 4 is evenly pressed on the mechanical seal workpiece, so that the force between the dynamic ring and the dynamic ring seat is even, and the two can be stably pressed together. After pressing, the mechanical seal fixed plate is installed to complete the assembly. When the mechanical seal is removed after assembly, the first and second drive mechanisms are simultaneously activated to quickly lift the pressure plate 4, allowing workers to remove the mechanical seal from the base 3 and place a new workpiece to be assembled. This embodiment utilizes the first drive mechanism to drive the pressure plate 4 to evenly press the workpiece to be assembled, eliminating the need for manual pressure to assemble the workpiece, protecting workers' personal safety, ensuring uniform force on the workpiece, and improving assembly efficiency, thereby reducing production costs.

[0028] The first drive mechanism includes a motor 6, a rotating rod 7, and a threaded sleeve 8. The motor 6 is fixedly mounted on the mounting plate 5. The output shaft of the motor 6 is fixedly connected to the rotating rod 7. The threaded sleeve 8 is fixedly mounted in the middle of the pressure plate 4. The middle portion of the rotating rod 7 has a threaded portion 701, and the rotating rod 7 is threadedly connected to the threaded sleeve 8. The output shaft of the motor 6 is fixedly connected to the rotating rod 7 via a coupling 9. Specifically, the motor 6 drives the rotating rod 7 to rotate via the coupling 9. The rotating rod 7 is threadedly connected to the threaded sleeve 8, so that the pressure plate 4 slides up and down to achieve compression of the workpiece.

[0029] A slide rail 10 is fixedly mounted on the vertical plate 2, a first slider 11 is fixedly mounted on the end of the pressure plate 4, and a second slider 12 is fixedly mounted on the end of the mounting plate 5. The first slider 11 and the second slider 12 are both slidably connected to the slide rail 10. Specifically, the first slider 11 and the second slider 12 are moved up and down via the slide rail 10, thereby enabling the mounting plate 5 and the pressure plate 4 to move up and down.

[0030] The second driving mechanism includes a cylinder 13, which is fixedly mounted on the transverse plate 1. The telescopic end of the cylinder 13 is fixedly connected to the mounting plate 5. Specifically, the cylinder 13 drives the mounting plate 5 to move up and down. Here, the cylinder 13 is only one form of driving the mounting plate 5 to slide up and down. Any method that can drive the mounting plate 5 to slide up and down can be used here, such as a motor 6 and a lead screw.

[0031] The two cylinders 13 are fixedly arranged on both sides of the slide rail 10. Specifically, the symmetrical arrangement of the two cylinders 13 can make the movement of the mounting plate 5 more uniform and more stable.

[0032] A docking sleeve 14 is also fixedly mounted on the base 3 and engages with the rotating rod 7. The bottom of the rotating rod 7 is chamfered. Specifically, due to the strong spring force in the workpiece, to prevent the workpiece from bouncing around while the pressure plate 4 is clamping it, the docking sleeve 14 and the rotating rod 7 are engaged and limited, preventing the workpiece from dislodging from the bottom of the pressure plate 4, thus preventing injury to the worker.

[0033] The pressing plate 4 is fixed with a notch 401. Specifically, after the workpiece is pressed, a mechanical seal fixing plate is used to stably connect it. Since the workpiece is at the bottom of the pressing plate 4, the pressing plate 4 is blocked, so the notch 401 is provided to facilitate the operator to operate.

[0034] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
