Description

Technical Field

[0001] The utility model relates to the technical field of cylinder liner honing, in particular to a honing tool for cylinder liner processing. Background Art

[0002] Cylinder liners are core components in important equipment such as internal combustion engines and compressors. Their machining quality significantly impacts the overall performance and lifespan of the equipment. The inner surface of the cylinder liner must be machined to extremely high levels of finish and precision to ensure smooth piston movement within the cylinder and minimize friction and wear. However, traditional cylinder liner machining methods often suffer from low machining accuracy, poor surface quality, and low machining efficiency. This significantly limits the stability and adaptability of existing technologies, particularly in large-scale production and for machining multiple cylinder liner specifications.

[0003] Traditional honing equipment relies primarily on manual adjustment of the honing head's machining position and pressure, which not only increases operational difficulty but also easily leads to human error. Existing honing equipment lacks sufficient flexibility and adaptability to handle diverse cylinder liners of varying specifications and materials, making it ineffective for various machining requirements. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a honing tool for cylinder liner processing, comprising a base, a vertical rod fixedly installed on the surface of the base, a connecting piece fixedly installed on the top of the vertical rod, a fixed seat fixedly installed inside the connecting piece, a cylinder liner support bushing fixedly installed inside the fixed seat, a No. 1 motor fixedly installed on the bottom of the base, a No. 1 screw rod fixedly installed on the output end of the No. 1 motor, a movable plate slidably connected on the surface of the vertical rod, a support rod fixedly installed on the surface of the movable plate, a shell fixedly installed on the top of the support rod, an active bevel gear rotatably connected to the inside of the shell, a No. 2 motor fixedly installed on the top of the support rod, a No. 2 screw rod rotatably connected on all four sides of the shell, a driven bevel gear fixedly installed on one end of the No. 2 screw rod located inside the shell, and a support block threadedly connected to the surface of the No. 2 screw rod.

[0006] Preferably, the support rod has a threaded groove formed inside, and the first screw is threadedly connected to the threaded groove inside the support rod. Here, the movable plate can be accurately moved on the surface of the vertical rod by the screw, so that the vertical rod can drive the support block on the housing to move, thereby facilitating the ejection of the honed cylinder liner.

[0007] Preferably, the output end of the second motor is fixedly connected to the driving bevel gear, which meshes with the driven bevel gear. This converts the motor's rotational motion into stable mechanical transmission, providing efficient power transfer and greater torque output. This allows the support block to move on the surface of the second screw, allowing adjustment for cylinder liners of varying inner diameters, improving the applicability of the honing tooling.

[0008] Preferably, a mounting block is fixedly mounted on the side of the housing, with a limit slot defined on the surface of the mounting block. A limit block is fixedly mounted on the bottom surface of the support block, and the limit block slides within the limit slot. This allows the support block to move stably outside the housing, thereby preventing deviation or irregular movement of the support block and allowing the support block to stably push the cylinder liner upward.

[0009] Preferably, the support blocks are arranged in four groups, symmetrically distributed around the housing. This evenly distributes pressure during the honing process, effectively avoiding machining defects caused by uneven force. The symmetrical distribution of the support blocks also improves workpiece stability, ensuring consistency and surface quality during machining.

[0010] Preferably, a fixing plate is provided on the top surface of the fixing seat, and a groove is defined on the bottom surface of the fixing plate. The top end of the cylinder liner support bushing is positioned within the groove, and a fastener is fixedly connected between the fixing plate and the fixing seat. The fastener connection helps further enhance the fixing strength and stability of the cylinder liner support bushing, ensuring that the cylinder liner will not shift due to vibration or other external forces during processing, thereby improving processing reliability and safety.

[0011] Preferably, a positioning block is fixedly mounted within the groove, and a positioning groove is formed on the surface of the cylinder liner support bushing. The position of the positioning block corresponds to the position of the positioning groove. This ensures that the cylinder liner is precisely positioned during installation, avoiding misalignment. This design improves installation accuracy, reduces human error, and further ensures the machining precision of the cylinder liner.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the present invention, the No. 1 motor drives the No. 1 screw to achieve precise movement of the movable plate, thereby driving the shell and the support block to move up and down, ensuring that the tooling can be flexibly adjusted according to the different heights of the cylinder liners during the honing process, thereby achieving precise processing of cylinder liners of different specifications. The No. 2 motor converts the rotational motion of the motor into stable mechanical transmission through the meshing transmission of the active bevel gear and the driven bevel gear, providing efficient power transmission, which not only ensures the stability of the honing process, but also provides sufficient torque output, and can adapt to cylinder liners of different sizes and hardness.

[0014] 2. In the present invention, the stability of the cylinder liner during the processing is ensured by the combined use of the fixing plate, the groove, the positioning block and the fastener. The positioning block corresponds one-to-one with the positioning groove on the cylinder liner support bushing, which effectively ensures the precise positioning of the cylinder liner and avoids displacement or error caused by vibration or external force during the processing. At the same time, the structural design greatly improves the reliability and safety during processing, ensures that the cylinder liner will not shift during operation, and thus improves the overall processing accuracy.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] See also Figure 1-6The utility model provides a technical solution: a honing tool for cylinder liner processing, comprising a base 1, a vertical rod 2 is fixedly installed on the surface of the base 1, a connecting piece 3 is fixedly installed on the top of the vertical rod 2, a fixing seat 4 is fixedly installed inside the connecting piece 3, a cylinder liner support bushing 5 is installed inside the fixing seat 4, a No. 1 motor 11 is fixedly installed on the bottom of the base 1, a No. 1 screw rod 12 is fixedly installed on the output end of the No. 1 motor 11, a moving plate 13 is slidably connected to the surface of the vertical rod 2, a support rod 14 is fixedly installed on the surface of the moving plate 13, a threaded groove 16 is opened inside the support rod 14, and a No. 1 screw rod 12 is threadedly connected in the thread groove 16 inside the support rod 14, ensuring that the movable plate 13 can be accurately moved on the surface of the vertical rod 2 through the screw rod, so that the vertical rod 2 can drive the support block 21 on the shell 15 to move, thereby facilitating the ejection of the cylinder sleeve after honing. The top of the support rod 14 is fixedly installed with the shell 15, and the interior of the shell 15 is rotatably connected to the active bevel gear 18. The top of the support rod 14 is fixedly installed with the No. 2 motor 17. The four sides of the shell 15 are rotatably connected to the No. 2 screw rod 19. The No. 2 screw rod 19 is located at one end inside the shell 15 and is fixed with the driven bevel gear 20. The output end of the No. 2 motor 17 is fixedly connected to the active bevel gear 18. The active bevel gear 18 and the driven bevel gear 20 are meshed transmissions, which can convert the rotational motion of the motor into a stable mechanical transmission, provide efficient power transmission and greater torque output, so that the support block 21 can move on the surface of the No. 2 screw rod 19, so that it can be adjusted according to cylinder sleeves of different inner diameters, thereby improving the applicability of the honing tooling. The surface of the No. 2 screw rod 19 is threadedly connected with the support block 21, and the side of the housing 15 is fixedly installed with a mounting block 23. The surface of the mounting block 23 is provided with a limiting groove 24, and the support block 21 is fixedly installed with a mounting block 23. A limit block 22 is fixedly installed on the bottom surface, and the limit block 22 is slidably connected inside the limit groove 24, so that the support block 21 can move stably on the outside of the shell 15, thereby avoiding the deviation or irregular movement of the support block 21, so that the support block 21 can stably push the cylinder sleeve upward. There are four groups of support blocks 21, and the four groups of support blocks 21 are symmetrically distributed around the shell 15. During the honing process, the pressure can be evenly distributed, and the processing defects caused by uneven force can be effectively avoided. The symmetrically distributed support blocks 21 can also improve the stability of the workpiece and ensure the consistency and surface quality during the processing.

[0027] Example 2

[0028] See also Figure 1-3The top surface of the fixing seat 4 is provided with a fixing plate 6, and the bottom surface of the fixing plate 6 is provided with a groove 9. The top side of the cylinder liner support bushing 5 is located inside the groove 9. A fastener 7 is fixedly connected between the fixing plate 6 and the fixing seat 4. The connection through the fastener 7 helps to further improve the fixing strength and stability of the cylinder liner support bushing 5, ensuring that the cylinder liner will not be displaced due to vibration or other external forces during the processing, thereby improving the reliability and safety of the processing. A positioning block 10 is fixedly installed inside the groove 9, and a positioning groove 8 is provided on the surface of the cylinder liner support bushing 5. The position of the positioning block 10 corresponds to the position of the positioning groove 8 one by one, which can ensure that the cylinder liner is accurately positioned during installation and avoid misplaced installation. This design is conducive to improving the accuracy of installation and reducing human errors, while also further ensuring the processing accuracy of the cylinder liner.

[0029] Working principle: The cylinder liner to be honed is inserted into the cylinder liner support bushing 5, and the fixing seat 4 firmly fixes the cylinder liner through the fixing plate 6 and the fastener 7. At the same time, the positioning block 10 cooperates with the positioning groove 8 to ensure the accurate positioning of the cylinder liner, so that the cylinder liner remains stable during the entire processing process to prevent displacement or deviation caused by vibration or external force. The active bevel gear 18 inside the housing 15 drives the driven bevel gear 20 through the rotation of the No. 2 motor 17 to complete the stable transmission of power, and converts the rotational motion of the motor into efficient mechanical energy through meshing transmission, and drives the No. 2 screw rod 19 to rotate. As the No. 2 screw rod 19 rotates, the support block 21 installed on the surface of the No. 2 screw rod 19 begins to move around the housing 15, and can be adaptively adjusted according to the inner diameter of the cylinder liner. To ensure the stable movement of the support block 21, a mounting block 23 and a limit groove 24 are designed on the side of the housing 15. The bottom of the support block 21 is slidably connected to the limit groove 24 through the limit block 22, which effectively Prevent the support block 21 from offsetting or irregularly moving during the movement, thereby ensuring that the support block 21 can apply uniform pressure when honing the cylinder liner. The four groups of support blocks 21 are symmetrically distributed around the shell 15. Driven by the No. 2 motor 17, the support blocks 21 are adjusted synchronously to ensure uniform pressure distribution during the processing, prevent uneven processing quality or defects on the cylinder liner surface, not only improve the stability of the workpiece, but also enable the tooling to handle cylinder liners of various specifications with high adaptability. After the honing is completed, by adjusting the height of the No. 1 screw rod 12 and the support rod 14, the No. 1 motor 11 starts working, and its output end drives the No. 1 screw rod 12 to rotate. The No. 1 screw rod 12 is connected to the threaded groove 16 inside the support rod 14 to achieve precise control of the moving plate 13 moving up and down along the vertical rod 2. As the moving plate 13 moves, the support rod 14 and the shell 15 are also adjusted up and down synchronously, so that the tooling can push the cylinder liner out from the inside of the tooling, making it convenient for personnel to take it.
