[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4 This utility model provides an automated crankshaft keying device, including a crankshaft keying device body 1; a servo motor 11 is fixedly connected to the side wall of the crankshaft keying device body 1; a screw 12 is fixedly connected to the output end of the servo motor 11; a connecting block 13 is threadedly connected to the side wall of the screw 12; the screw 12 passes through the wall of the connecting block 13 and is threadedly connected to it; a guide rod 14 is fixedly connected to the side wall of the servo motor 11; a slider 15 is sleeved on the outside of the guide rod 14; the slider 15 and the connecting block 13 are fixedly connected; the connecting block 13... A push plate 16 is fixedly connected to the side wall; a pair of spring rods 17 are symmetrically arranged on the side wall of the push plate 16; the ends of the spring rods 17 are fixedly connected to the same first cleaning brush plate 18; a connecting rod 19 is fixedly connected to the side wall of the first cleaning brush plate 18; in use, after the workpiece is pressed, the servo motor 11 is started, and the servo motor 11 drives the screw 12 to rotate. Under the threaded engagement between the screw 12 and the connecting block 13, the connecting block 13 can be moved as the screw 12 rotates, and at the same time the slider 15 slides on the side wall of the guide rod 14, thereby moving the connecting block 13. After the movement is limited, the workpiece above the crankshaft keying device body 1 can be pushed out from under the pressing mechanism by the push plate 16, so that the operator can pick it up. During the movement, the push plate 16 will push the first cleaning brush plate 18 by the elasticity of the spring rod 17, so that the first cleaning brush plate 18 can fully contact the side wall of the crankshaft keying device body 1, thereby cleaning the side wall of the crankshaft keying device body 1 and sweeping away the iron filings generated during pressing. At the same time, the connecting rod 19 can be used to move the multiple bristles on the side wall of the first cleaning brush plate 18. The fixed connection allows the parts to be concentrated together during cleaning. After the push plate 16 is used, the screw 12 is reversed by the servo motor 11 to reset the push plate 16. During this process, the push plate 16 pushes out the workpiece, which makes it convenient to pick up the workpiece after pressing and improves the safety of the crankshaft key pressing device body 1 during use. At the same time, the first cleaning brush plate 18 can clean the iron filings remaining on the surface of the crankshaft key pressing device body 1, and the connecting rod 19 can enhance the cleaning effect of the first cleaning brush plate 18.

[0026] Furthermore, such as Figure 2As shown, a pair of piston cylinders 2 are fixedly connected to the side wall of the crankshaft keying device body 1; the piston cylinders 2 are symmetrically arranged on both sides of the crankshaft keying device body 1 and have the same structure; a piston rod 21 is slidably connected to the inner side wall of the piston cylinder 2; a spring 22 is fixedly connected between the piston rod 21 and the piston cylinder 2; an exhaust pipe 23 is fixedly connected to the side wall of the piston cylinder 2; the exhaust pipe 23 penetrates the wall of the piston cylinder 2 and is fixedly connected to it; a pair of pressing rods 24 are symmetrically fixedly connected to the side wall of the crankshaft keying device body 1; in use, during the pressing process of the crankshaft keying device body 1, when the pressing mechanism descends to a certain position, the pressing rods 24 can press against the crankshaft keying device body 1. When the piston rod 21 is pressed, the spring 22 extends and retracts. At this time, the gas in the piston cylinder 2 can be squeezed out through the piston rod 21 and discharged to the outside through the exhaust pipe 23, thereby blowing air onto the top of the crankshaft key pressing device body 1 to blow away the dust and impurities attached to the surface of the workpiece. After the pressing mechanism is raised, the elasticity of the spring 22 will push the piston rod 21 to return to its original position. During this process, the air blowing through the exhaust pipe 23 can clean the dust and impurities attached to the surface of the workpiece, reduce the impact of dust and impurities remaining between the workpiece and the pressing mechanism on the pressing effect, and thus increase the pressing effect on the workpiece.

[0027] Furthermore, such as Figure 1 , Figure 2 , Figure 4 As shown, the connecting block 13 has a guide hole 3 on its side wall; a top ball 31 is fixedly connected to the side wall of the guide hole 3; a funnel 32 is fixedly connected to the side wall of the crankshaft keying device body 1; a ball bearing 33 is slidably connected to the inner side wall of the funnel 32; in use, a certain amount of lubricating oil is first injected into the funnel 32. As the connecting block 13 moves, when it moves below the funnel 32, the top ball 31 will squeeze the ball bearing 33. At this time, the lubricating oil will flow out through the gap between the ball bearing 33 and the funnel 32, flowing into the side wall of the guide hole 3, and then flowing along the guide hole 3. The lubricating oil drips onto the side wall of the screw 12, thus lubricating the rotation between the screw 12 and the connecting block 13. When the top ball 31 moves away from under the ball 33, the weight of the ball 33 will block the funnel 32, preventing the lubricating oil from flowing out. During this process, the lubricating oil dripping from the funnel 32 onto the side wall of the screw 12 can lubricate the rotation between the screw 12 and the connecting block 13, improving the smoothness of the movement of the connecting block 13, and reducing the occurrence of rust on the screw 12 affecting the movement of the connecting block 13, thereby increasing the service life of the screw 12.

[0028] Furthermore, such as Figure 4As shown, a filter screen plate 4 is hinged to the side wall of the funnel 32; an elastic ball 41 is fixed to the side wall of the filter screen plate 4; an mounting block 42 is fixed to the side wall of the funnel 32; and a slot is provided on the side wall of the mounting block 42. In use, the filter screen plate 4 is placed over the funnel 32, and the elastic ball 41 is pressed into the slot on the side wall of the mounting block 42. The elastic ball 41 contracts under pressure, and after being pressed into the slot, it automatically recovers its elasticity and locks into the mounting block 42, thus fixing the filter screen plate 4. The filter screen plate 4 then blocks external dust and impurities from entering the funnel 32. Simultaneously, the amount of lubricating oil in the funnel 32 can be observed through the filter screen plate 4. During this process, the filter screen plate 4 acts as a dustproof barrier for the funnel 32, improving the lubrication effect of the lubricating oil in the funnel 32. The elastic ball 41 also serves to fix the filter screen plate 4, enhancing its stability during use.

[0029] Furthermore, such as Figure 2 , Figure 3 As shown, a slide rail 5 is fixedly connected to the side wall of the push plate 16; an insert block 51 is slidably connected to the inner side wall of the slide rail 5; a rubber pad 52 is fixedly connected to the side wall of the insert block 51; the insert block 51 and the spring rod 17 are fixedly connected; in use, by inserting the insert block 51 into the slide rail 5, the rubber pad 52 is fully in contact with the slide rail 5 and a certain friction is generated, which can fix the spring rod 17. In this process, by fixing the insert block 51 into the slide rail 5, the first cleaning brush plate 18 can be easily disassembled and installed, which can improve the ease of disassembling and replacing the first cleaning brush plate 18, thereby increasing the practicality of the first cleaning brush plate 18.

[0030] Furthermore, such as Figure 4 As shown, a rotating rod 6 is rotatably connected to the side wall of the filter screen plate 4; a plurality of second cleaning brush plates 61 are evenly fixed to the side wall of the rotating rod 6; in use, by holding and rotating the rotating rod 6, the second cleaning brush plates 61 move on the surface of the filter screen plate 4. At this time, the second cleaning brush plates 61 can be used to clean the surface of the filter screen plate 4, sweeping away the dust and impurities attached thereon. In this process, the cleaning of the surface of the filter screen plate 4 by the second cleaning brush plates 61 can clean the dust and impurities attached to the surface of the filter screen plate 4, reduce the accumulation of dust and impurities, and thus increase the clarity when viewing through the filter screen plate 4.

[0031] Furthermore, such as Figure 3As shown, a pair of limiting blocks 7 are symmetrically fixed to the side wall of the slide rail 5. In use, when the insert 51 is inserted into the slide rail 5, the insert 51 will contact the limiting blocks 7 on both sides and slide on the side wall of the limiting blocks 7. At this time, the insert 51 will slide towards the middle of the limiting blocks 7 on both sides. In this process, the limiting blocks 7 can limit the insertion of the insert 51 into the slide rail 5, improve the convenience of installing the insert 51, and thus increase the installation speed of the first cleaning brush plate 18.

[0032] Working principle: During use, after the workpiece is pressed, the servo motor 11 is started, which drives the screw 12 to rotate. With the screw 12 threadedly engaging with the connecting block 13, the connecting block 13 moves as the screw 12 rotates. Simultaneously, the slider 15 slides on the side wall of the guide rod 14, limiting the movement of the connecting block 13. Then, the push plate 16 pushes the workpiece above the crankshaft key pressing device body 1 out from under the pressing mechanism for easy removal by the operator. During the movement of the push plate 16, the elasticity of the spring rod 17 pushes the first cleaning brush plate 18, causing it to fully contact the side wall of the crankshaft key pressing device body 1, thereby cleaning the side wall of the crankshaft key pressing device body 1 and removing the residue produced during pressing. Raw iron filings are swept away, and the connecting rod 19 can be used to fix and connect multiple bristles on the side wall of the first cleaning brush plate 18, so that they are concentrated together during cleaning. After the push plate 16 is used, the servo motor 11 drives the screw 12 to reverse and reset the push plate 16. During use, when the crankshaft key pressing device body 1 is pressing, when the pressing mechanism descends to a certain position, the pressing rod 24 can press the piston rod 21, causing the spring 22 to extend and retract. At this time, the piston rod 21 can squeeze the gas in the piston cylinder 2 and discharge it to the outside through the exhaust pipe 23, thereby blowing air onto the top of the crankshaft key pressing device body 1 to blow away dust and impurities attached to the surface of the workpiece. After the pressing mechanism is raised, the spring 22 is used to push the piston rod 21 to return the workpiece to its original position. The elasticity of the piston rod 21 will push it to reset. In use, a measured amount of lubricating oil is first injected into the funnel 32. As the connecting block 13 moves, when it reaches below the funnel 32, the top ball 31 will press against the ball 33. At this time, the lubricating oil will flow out through the gap between the ball 33 and the funnel 32, flowing into the side wall of the guide hole 3. Then, it will drip down the guide hole 3 onto the side wall of the screw 12, thus lubricating the rotation between the screw 12 and the connecting block 13. When the top ball 31 moves away from below the ball 33, the weight of the ball 33 will block the funnel 32, preventing further lubrication. In use, the filter screen 4 is placed over the funnel 32, and the elastic ball 41 is pressed into the side wall of the mounting block 42. When the elastic ball 41 is compressed within the groove, it contracts. After being pressed into the groove, the elastic ball 41 automatically recovers its elasticity and locks into the mounting block 42, thus fixing the filter screen 4. The filter screen 4 then blocks external dust and impurities from entering the funnel 32. Simultaneously, the lubricating oil level in the funnel 32 can be observed through the filter screen 4. In use, by inserting the insert block 51 into the slide rail 5, the rubber pad 52 makes full contact with the slide rail 5, generating a certain friction, thus fixing the spring rod 17. During use, by holding and rotating the rotating rod 6, the second cleaning brush 61 moves across the surface of the filter screen 4, allowing for cleaning of the filter screen 4 surface.After sweeping away the accumulated dust and impurities, during use, when inserting the insert 51 into the slide rail 5, the insert 51 will contact the two side limit blocks 7, causing it to slide on the side walls of the limit blocks 7. At this time, the insert 51 will slide towards the middle of the two side limit blocks 7.
