[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, a servo press anti-sticking device includes a frame 1. A servo motor 12 is fixedly connected to the top of the frame 1. A screw 13 is fixedly connected to the output end of the servo motor 12, and the screw 13 and the frame 1 are through-connected and rotatably connected. A connecting plate 14 is threadedly connected to the outer wall of the screw 13. Vertical rods 15 are symmetrically fixedly connected to the top of the connecting plate 14. The vertical rods 15 and the frame 1 are slidably connected. A pressure plate 16 is fixedly connected to the bottom of the connecting plate 14. An electromagnet 111 is installed on the inner wall of the pressure plate 16. A bearing 112 is provided at the bottom of the electromagnet 111, and the bearing 112 can be attracted and fixed by the electromagnet 111. An air outlet ring 17 is fixedly connected to the inner wall of the pressure plate 16, and the inner wall of the air outlet ring 17 is multi-holeed; the bearing 112 is located inside the air outlet ring 17; a flexible hose 18 is connected to one side of the air outlet ring 17; a first cylinder 19 is fixedly connected to the top of the inner wall of the frame 1; a support base 110 is fixedly connected to the output end of the first cylinder 19; the support base 110 and the frame 1 are slidably connected; a bearing seat 113 is provided on the top of the support base 110; during operation, the bearing seat 113 can be placed on top of the support base 110, and the support base 110 can be slowly slid along the frame 1 by controlling the first cylinder 19, so that the support base 110 can be at the bottom of the pressure plate 16 and in a concentric state. Then, the bearing 112 can be installed inside the pressure plate 16, and the electromagnet 111 can be energized to attract and fix the bearing 112. Then, the servo motor 12 can be started to make the screw 13 rotate. The screw 13 will drive the connecting plate 14 through the thread drive to slide along the frame 1. The upright 15 will provide a guiding function for the connecting plate 14. During the process, the pressure plate 16 will bring the bearing 112 closer to the bearing seat 113 until the bearing 112 is pressed into the bearing seat 113. At this time, the power supply to the electromagnet 111 can be cut off, and the air pump can be connected to the hose 18 to make the air flow out from the inner wall of the air outlet ring 17. Under the action of air, the bearing 112 and the pressure plate 16 will be pressed together. The sealed cavity formed between the plates 16 is under positive pressure, so that the bearing 112 can be smoothly separated from the pressure plate 16. Then, the pressure plate 16 can be reset by the servo motor 12 and the support seat 110 can be reset by the first cylinder 19. Finally, the pressed bearing seat 113 can be removed from the support seat 110. Through the cooperation of the air outlet ring 17 and the hose 18, the separation between the pressure plate 16 and the bearing 112 can be accelerated by the air impact after the pressure plate 16 presses the bearing 112. This reduces the situation where the components of the bearing 112 and the bearing seat 113 are lifted up as the pressure plate 16 is reset due to adhesion, which facilitates the device to remove the pressed components.

[0026] Please see Figure 4As shown, multiple flow dividers 2 are fixedly connected to the inner wall of the outlet ring 17; the surface of the flow divider 2 is porous; the flow divider 2 and the outlet ring 17 are connected; by setting the flow divider 2, the air jet ejected from the outlet ring 17 will enter the interior of the flow divider 2 and be ejected through the porous structure on the surface of the flow divider 2, making the airflow direction more extensive, which facilitates the gas to quickly fill the sealed cavity between the pressure plate 16 and the bearing 112, so as to perform air jet separation of the pressure plate 16; by setting the flow divider 2, the flow divider 2 will accelerate the gas filling speed between the pressure plate 16 and the bearing 112, which facilitates the device to separate the air jet between the pressure plate 16 and the bearing 112.

[0027] Please see Figure 3 and Figure 4 As shown, multiple fixing rings 3 are fixed to the outside of the pressure plate 16; the fixing rings 3 are used to reinforce the hose 18; by setting the fixing rings 3, the hose 18 will be fixed by the fixing rings 3 during the up and down movement of the pressure plate 16, so as to reduce the shaking of the hose 18 when it moves up and down or when a high-speed airflow rushes into it, and reduce the friction between it and other components.

[0028] Please see Figure 2 and Figure 5 As shown, a second cylinder 4 is fixedly connected to the top of the support base 110; a circular plate 42 is rotatably connected to the output end of the second cylinder 4; the circular plate 42 and the support base 110 are rotatably connected; multiple sliding grooves 43 are formed on the surface of the circular plate 42; a connecting frame 44 is slidably connected to the inner wall of the sliding groove 43; a slide rail 46 is fixedly connected to the top of the support base 110; the connecting frame 44 and the slide rail 46 are slidably connected; a clamping plate 45 is fixedly connected to the end of the connecting frame 44; the bearing seat 113 is located between the multiple clamping plates 45; before pressing, the bearing seat 113 can be placed on top of the slide rail 46, and the circular plate 42 can be rotated by starting the second cylinder 4, and the sliding grooves 43 will follow. As the circular plate 42 rotates, the connecting frame 44 is guided to rotate. At this time, multiple connecting frames 44 will move simultaneously along the slide rail 46 and slide groove 43 under the guidance of the slide rail 46 and slide groove 43 and move closer to the bearing seat 113. Multiple clamping plates 45 will simultaneously squeeze and clamp the outer wall of the bearing seat 113, realizing the device to quickly fix the bearing seat 113. At the same time, when clamping the bearing seat 113, the clamping plates 45 can also center and clamp the bearing seat 113, improving the accuracy of the position of the bearing seat 113 during clamping, thereby improving the stability of the bearing seat 113 during press-fitting and further reducing the situation where it adheres to the pressure plate 16 due to the adhesion between the bearing 112 and the pressure plate 16.

[0029] Please see Figure 5As shown, an elastic rope 5 is fixed between adjacent clamping plates 45; multiple pressure blocks 52 are fixed in the middle of the elastic rope 5; the outer wall of the pressure block 52 is an arc-shaped structure; by setting the elastic rope 5 and the pressure block 52, when the clamping plate 45 clamps the bearing seat 113, the elastic rope 5 will appropriately recover from the stretched state, and the pressure block 52 will squeeze the top of the outer wall of the bearing seat 113, so that the bearing seat 113 can be subjected to more vertical compression, improving the stability of the bearing seat 113. At the same time, the surface of the pressure block 52 can be made of a smooth material to reduce the friction generated when it contacts the surface of the bearing seat 113.

[0030] Please see Figure 5 As shown, a rubber pad 6 is fixed to the inner wall of the clamping plate 45; the rubber pad 6 is located between the bearing seat 113 and the clamping plate 45; by setting the rubber pad 6, when the clamping plate 45 clamps the bearing seat 113 on the outer wall, the rubber pad 6 will contact the bearing seat 113 before the clamping plate 45. Because the rubber pad 6 is a flexible material, the rubber pad 6 will disperse the squeezing force on the surface of the bearing seat 113, so as to reduce the damage to the bearing seat 113 caused by excessive squeezing by the clamping plate 45.

[0031] Working principle: The bearing seat 113 is placed on top of the support seat 110, and the support seat 110 is slowly slid along the frame 1 by controlling the first cylinder 19, so that the support seat 110 is at the bottom of the pressure plate 16 and in a concentric state. Then, the bearing 112 is installed inside the pressure plate 16, and the electromagnet 111 is energized to attract and fix the bearing 112. Then, the servo motor 12 is started to rotate the screw 13. The screw 13 drives the connecting plate 14 through the thread transmission, so that it slides along the frame 1. The upright 15 provides a guiding function for the connecting plate 14. During the process, the pressure plate 16 will bring the bearing 112 closer to the bearing seat 113 until the bearing 112 is pressed into the shaft. Inside the bearing seat 113, the power supply to the electromagnet 111 can be cut off, and the air pump can be connected to the hose 18 to make the airflow spray out from the inner wall of the air outlet ring 17. Under the action of the air jet, the sealed cavity formed between the bearing 112 and the pressure plate 16 will be in a positive pressure state, so that the bearing 112 can be smoothly separated from the pressure plate 16. Then, the pressure plate 16 can be reset by the servo motor 12, and the support seat 110 can be reset by the first cylinder 19. Finally, the press-fitted bearing seat 113 can be removed from the support seat 110. By setting the flow divider 2, the air jet sprayed out from the air outlet ring 17 will enter the interior of the flow divider 2 and be sprayed out through the porous structure on the surface of the flow divider 2, so that the airflow direction is more extensive. This facilitates rapid gas filling of the sealed cavity between the pressure plate 16 and the bearing 112, enabling gas ejection of the pressure plate 16. The diverter plate 2 accelerates the gas filling speed between the pressure plate 16 and the bearing 112, facilitating gas ejection separation between them. The retaining ring 3 ensures that the hose 18 is fixed as it moves up and down with the pressure plate 16, reducing vibration during up-and-down movement or when high-speed airflow enters, and minimizing friction between the hose and other components. Before pressing, the bearing seat 113 can be placed on top of the slide rail 46, and the second cylinder 4 can be activated to move the circular plate 42... As the plate 42 rotates, the slide groove 43 guides the connecting frame 44 to rotate. At this time, multiple connecting frames 44 move along the slide rail 46 and slide groove 43 simultaneously under the guidance of the slide rail 46 and slide groove 43 and move closer to the bearing seat 113. Multiple clamping plates 45 simultaneously squeeze and clamp the outer wall of the bearing seat 113, realizing the device to quickly fix the bearing seat 113. At the same time, when clamping the bearing seat 113, the clamping plates 45 can also center and clamp the bearing seat 113, improving the accuracy of the position of the bearing seat 113 during clamping, thereby improving the stability of the bearing seat 113 during press-fitting and further reducing the situation where it adheres to the pressure plate 16 due to the adhesion between the bearing 112 and the pressure plate 16.By setting up the elastic rope 5 and the pressure block 52, when the clamping plate 45 clamps the bearing seat 113, the elastic rope 5 will appropriately recover from its stretched state, and the pressure block 52 will press against the top of the outer wall of the bearing seat 113, so that the bearing seat 113 can be subjected to more vertical compression, improving the stability of the bearing seat 113. At the same time, the surface of the pressure block 52 can be made of a smooth material to reduce the friction generated when it comes into contact with the surface of the bearing seat 113. By setting up the rubber pad 6, when the clamping plate 45 clamps the outer wall of the bearing seat 113, the rubber pad 6 will come into contact with the bearing seat 113 before the clamping plate 45. Because the rubber pad 6 is a flexible material, it will disperse the compression force on the surface of the bearing seat 113, thereby reducing the damage to the bearing seat 113 caused by excessive compression from the clamping plate 45.
