Description

Technical Field

[0001] This utility model relates to the field of cylinder processing technology, specifically a general-purpose cylinder inner hole grinding device. Background Technology

[0002] An internal combustion engine cylinder liner is a component of an internal combustion engine with a cylindrical structure. The cylinder liner can be inserted into the internal combustion engine body, and its inner wall forms the working surface of the cylinder. Together with the cylinder head and piston, it forms the combustion chamber. In the production and processing of cylinder liners, the inner hole of the cylinder liner needs to be ground and polished to ensure that the cylinder inside the cylinder liner can work normally.

[0003] However, the existing main method for grinding the cylinder inner cavity is to fix the grinding roller on the eccentric wheel, and then drive the eccentric wheel to rotate through the motor, so that the grinding roller grinds the cylinder inner cavity around its perimeter. This operation method requires changing different eccentric wheels when grinding the inner cavity of cylinders with different inner diameters, which is not only cumbersome to operate, but also time-consuming and labor-intensive, resulting in inconvenience in grinding the cylinder inner hole. Therefore, a universal cylinder inner hole grinding device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A universal cylinder inner hole grinding device of this utility model includes a base. A first hydraulic cylinder is fixedly connected to the inner side of the base. A moving block is fixedly connected to the output end of the first hydraulic cylinder. The moving block and the base are slidably connected. A gear is rotatably connected to the outer side of the moving block. A screw with positive and negative threads is rotatably connected to the outer side of the gear. A clamping block is threadedly connected to the outer side of the screw with positive and negative threads. The clamping block and the gear are slidably connected. A rack meshes with the outer side of the gear. A second hydraulic cylinder is fixedly connected to the outer side of the base. The output end of the second hydraulic cylinder is fixedly connected to the rack. The rack and the base are slidably connected. A third hydraulic cylinder is fixedly connected to the outer side of the base. A lifting plate is fixedly connected to the output end of the third hydraulic cylinder. A motor is fixedly connected to the inner side of the lowering plate, and a grinding roller is fixedly connected to the output end of the motor. This step involves setting up a first hydraulic cylinder, a second hydraulic cylinder, a rack, and a gear. In use, the cylinder is placed between the clamping blocks, and then the clamping blocks are driven by the forward and reverse threaded screws to clamp cylinders of different sizes. Then, the first and second hydraulic cylinders are started synchronously, causing the gear and rack to move synchronously until the inner wall of the cylinder is aligned with the grinding roller. Then, the third hydraulic cylinder drives the grinding roller to insert into the inner hole of the cylinder and rotate for grinding. Then, the rack is moved separately, causing the gear to rotate forward or backward, so that the unground inner wall of the cylinder can move to fit against the grinding roller. This allows the grinding roller to grind the inner wall of cylinders of different sizes without changing the eccentric wheel of different sizes, improving the convenience of the device.

[0006] Preferably, a reinforcing plate is fixedly connected to the outer side of the clamping block, and a reinforcing rod is slidably connected to the inner side of the gear. The reinforcing plate and the reinforcing rod are slidably connected. This step involves setting a reinforcing plate and a reinforcing rod. The surface of the reinforcing plate has multiple holes and slots. After the clamping block moves to fix cylinders of different sizes, the reinforcing rod is inserted into the holes and slots on the surface of the reinforcing plate, and then inserted into the inner side of the gear, thereby further fixing the position of the clamping block. This makes it less likely to loosen due to external forces, which would cause the cylinder clamping to become unstable, thus improving the stability of the device.

[0007] Preferably, a clamping plate is fixedly connected to the outer side of the third hydraulic cylinder on one side, and the clamping plate is slidably connected to the rack. By setting the clamping plate, the rack can further restrict its movement trajectory when it moves, making it less prone to shaking, which would cause the gear to wobble and improve the stability of the device.

[0008] Preferably, a downward pressure spring is fixedly connected to the outer side of the lifting plate, and a pressure plate is fixedly connected to one end of the downward pressure spring. The pressure plate and the grinding roller are slidably connected. By setting the downward pressure spring and the pressure plate, when the lifting plate moves the grinding roller to press against the inner wall of the cylinder, the pressure plate will simultaneously press against the upper side of the cylinder, thereby blocking the inner hole of the cylinder. This allows the debris generated during grinding to be confined inside the cylinder, making it less likely to splash around and easier to recycle, thus improving the convenience of using the device.

[0009] Preferably, a suction pipe is fixedly connected to the inner side of the pressure plate, and one end of the suction pipe is connected to a vacuum cleaner. The vacuum cleaner and the lifting plate are fixedly connected. By setting up the suction pipe and the vacuum cleaner, after the pressure plate restricts the debris, the vacuum cleaner drives the air and debris to be sucked into the inner side of the pressure plate through the suction pipe, so that the debris is quickly collected while being ground, which further improves the convenience of using the device.

[0010] Preferably, a guide rod is fixedly connected to the outside of the pressure plate, and the guide rod is slidably connected to the lifting plate. This step, by setting the guide rod, further restricts the movement trajectory of the pressure plate when it moves up and down, making its movement more stable and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a first hydraulic cylinder, a second hydraulic cylinder, a rack and a gear, allows the cylinder to be placed between clamping blocks during use. Then, the clamping blocks are driven by the forward and reverse threaded screws to clamp cylinders of different sizes. The first and second hydraulic cylinders are then started synchronously, causing the gear and rack to move synchronously until the inner wall of the cylinder is aligned with the grinding roller. Then, the third hydraulic cylinder drives the grinding roller to insert into the inner hole of the cylinder and rotate for grinding. The rack is then moved separately, causing the gear to rotate forward or backward, so that the unground inner wall of the cylinder can move to fit against the grinding roller. This allows the grinding roller to grind the inner wall of cylinders of different sizes without the need to change to different sized eccentric wheels, improving the convenience of the device.

[0013] 2. This utility model uses a reinforcing plate and a reinforcing rod. The surface of the reinforcing plate has multiple holes and slots. After the clamping block moves to fix the cylinders of different sizes, the reinforcing rod is inserted into the holes and slots on the surface of the reinforcing plate, and then into the gear, thereby further fixing the position of the clamping block. This makes it less likely to loosen due to external force, which would cause the cylinder clamping to become unstable, thus improving the stability of the device. 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. 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.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a general-purpose cylinder bore grinding device includes a base 1. A first hydraulic cylinder 2 is fixedly connected to the inner side of the base 1. A moving block 3 is fixedly connected to the output end of the first hydraulic cylinder 2. The moving block 3 is slidably connected to the base 1. A gear 4 is rotatably connected to the outer side of the moving block 3. A threaded screw 5 is rotatably connected to the outer side of the gear 4. A clamping block 6 is threadedly connected to the outer side of the threaded screw 5. The clamping block 6 is slidably connected to the gear 4. A rack 7 meshes with the outer side of the gear 4. A second hydraulic cylinder 8 is fixedly connected to the outer side of the base 1. The output end of the second hydraulic cylinder 8 is fixedly connected to the rack 7. The rack 7 is slidably connected to the base 1. A third hydraulic cylinder 9 is fixedly connected to the outer side of the base 1. A lifting plate 10 is fixedly connected to the output end of the third hydraulic cylinder 9. A motor 11 is fixedly connected to the inner side of the lifting plate 10. The output end of the motor 11 is fixedly connected to a grinding roller 12. This step involves setting up a first hydraulic cylinder 2, a second hydraulic cylinder 8, a rack 7, and a gear 4. In use, the cylinder is placed between clamping blocks 6, and then the clamping blocks 6 are driven by the forward and reverse threaded screws 5 to clamp cylinders of different sizes. Then, the first hydraulic cylinder 2 and the second hydraulic cylinder 8 are started synchronously, so that the gear 4 and the rack 7 move synchronously until the inner wall of the cylinder is aligned with the grinding roller 12. Then, the third hydraulic cylinder 9 drives the grinding roller 12 to be inserted into the inner hole of the cylinder and rotated for grinding. Then, the rack 7 is moved separately, so that the gear 4 rotates forward or backward, so that the unground inner wall of the cylinder can be moved to be close to the grinding roller 12. This allows the grinding roller 12 to grind the inner wall of cylinders of different sizes without changing the eccentric wheel of different sizes, improving the convenience of the device.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, a reinforcing plate 13 is fixedly connected to the outer side of the clamping block 6, and a reinforcing rod 14 is slidably connected to the inner side of the gear 4. The reinforcing plate 13 and the reinforcing rod 14 are slidably connected. In this step, by setting the reinforcing plate 13 and the reinforcing rod 14, multiple holes and slots are opened on the surface of the reinforcing plate 13. After the clamping block 6 moves to fix the cylinders of different sizes, the reinforcing rod 14 is inserted into the holes and slots on the surface of the reinforcing plate 13, and then inserted into the inner side of the gear 4, thereby further fixing the position of the clamping block 6, making it less likely to loosen due to external force and cause the cylinder clamping to become unstable, thus improving the stability of the device.

[0025] Furthermore, such as Figure 1 As shown, a clamping plate 15 is fixedly connected to the outer side of the third hydraulic cylinder 9 on one side, and the clamping plate 15 and the rack 7 are slidably connected. By setting the clamping plate 15, when the rack 7 moves, the clamping plate 15 can further restrict its movement trajectory, making it less prone to shaking, which would cause the gear 4 to shake, thus improving the stability of the device.

[0026] Furthermore, such as Figure 1As shown, a downward pressure spring 16 is fixedly connected to the outer side of the lifting plate 10, and a pressure plate 17 is fixedly connected to one end of the downward pressure spring 16. The pressure plate 17 and the grinding roller 12 are slidably connected. By setting the downward pressure spring 16 and the pressure plate 17, when the lifting plate 10 drives the grinding roller 12 to move close to the inner wall of the cylinder, the pressure plate 17 will simultaneously press against the upper side of the cylinder, thereby blocking the inner hole of the cylinder. This allows the debris generated during grinding to be confined inside the cylinder, making it less likely to splash around and easier to recycle, thus improving the convenience of using the device.

[0027] Furthermore, such as Figure 1 As shown, a suction pipe 18 is fixedly connected to the inner side of the pressure plate 17, and one end of the suction pipe 18 is connected to a vacuum cleaner 19. The vacuum cleaner 19 is fixedly connected to the lifting plate 10. In this step, by setting up the suction pipe 18 and the vacuum cleaner 19, after the pressure plate 17 restricts the debris, the vacuum cleaner 19 drives the air and debris to be sucked into the inner side of the suction pipe 18 through the suction pipe, so that the debris is quickly collected while being ground, which further improves the convenience of using the device.

[0028] Furthermore, such as Figure 1 As shown, a guide rod 20 is fixedly connected to the outside of the pressure plate 17, and the guide rod 20 is slidably connected to the lifting plate 10. This step, by setting the guide rod 20, further restricts the movement trajectory of the pressure plate 17 when it moves up and down, making its movement more stable and improving the stability of the device.

[0029] Working principle: During use, the cylinder is placed between the clamping blocks 6, and then the clamping blocks 6 are moved by the forward and reverse threaded screws 5. The clamping blocks 6 clamp cylinders of different sizes. Then, the first hydraulic cylinder 2 and the second hydraulic cylinder 8 are started synchronously, so that the gear 4 and the rack 7 move synchronously until the inner wall of the cylinder is aligned with the grinding roller 12. Then, the third hydraulic cylinder 9 drives the lifting plate 10 to press down. The lifting plate 10 drives the grinding roller 12 to insert into the inner hole of the cylinder and rotate for grinding. At the same time, the lifting plate 10 drives the pressure plate 17 to press against the upper side of the cylinder for shielding. The vacuum cleaner 19 is started. The vacuum cleaner 19 drives the grinding debris to be sucked into the vacuum cleaner 19 through the suction pipe 18. Then, the second hydraulic cylinder 8 is started separately. The second hydraulic cylinder 8 drives the rack 7 to move, so that the gear 4 rotates forward or backward, so that the un-ground inner wall of the cylinder can move to press against the grinding roller 12 for grinding.
