Description

Technical Field

[0001] This utility model relates to the technical field of cylinder liner inner hole machining equipment, and in particular to a cylinder liner inner hole machining device. Background Technology

[0002] The inner surface of the cylinder liner is directly exposed to high-temperature, high-pressure combustion gases and constantly experiences high-speed sliding friction with the piston rings and piston skirt. The outer surface is in contact with cooling water, generating severe thermal stress under significant temperature differences and becoming susceptible to corrosion. The lateral thrust of the piston on the cylinder liner not only exacerbates the friction on its inner surface but also causes it to bend. When the lateral thrust changes direction, the piston also impacts the cylinder liner.

[0003] Currently, cylinder liner production mainly involves machining its inner bore and outer surface. When machining the inner surface, it is necessary to grind and polish it. However, existing grinding equipment requires complex debugging to ensure that it can meet the needs of cylinder liners with different diameters.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] See Figures 1-4 This utility model provides a cylinder liner inner hole machining device, which includes a top plate 2 and a bottom plate 4 for positioning the cylinder liner 3. The bottom plate 4 and the top plate 2 cooperate to position the cylinder liner 3, ensuring the subsequent polishing process. The bottom plate 4 is provided with an inflation head 42, which can supply gas to the inside of the polishing bladder, thereby ensuring the subsequent polishing process. A polishing mechanism 1 is rotatably connected to the top plate 2. The polishing mechanism 1 includes a rotating shaft rotatably and slidably connected to the top plate 2. The bottom of the rotating shaft is provided with a polishing bladder, and the bottom of the rotating shaft is provided with an inflation port that cooperates with the inflation head 42. The inflation port communicates with the inside of the polishing bladder when the inflation head 42 is inserted, and seals the polishing bladder when the inflation head 42 is withdrawn from the inflation port, ensuring the contact force between the polishing bladder and the inner wall of the cylinder liner 3 during polishing, thereby polishing the cylinder liner 3.

[0020] Preferably, the bottom of the rotating shaft of this invention is provided with a sliding hole 12, and a sealing head 7 is slidably connected inside the sliding hole 12. The sealing head 7 seals the polishing bladder to ensure the sealing effect of the polishing bladder. The end of the sliding hole 12 is provided with a wedge-shaped structure, and an air hole 11 communicating with the polishing bladder is opened on the wedge-shaped structure. The air hole 11 is provided on the wedge-shaped structure to ensure that the air hole 11 can be sealed by the sealing head 7. The air inlet is connected to the air hole 11. The bottom of the sealing head 7 is provided with a bevel structure that cooperates with the wedge-shaped structure. When the bevel structure is close to the wedge-shaped structure, it seals the air hole 11. A thrust spring 6 is provided between the sealing head 7 and the sliding hole 12. Under the action of the thrust spring 6, the sealing head 7 is pressed against the wedge-shaped structure, thereby sealing the air hole 11.

[0021] In addition, the inflation head 42 of this utility model is provided with an air passage 43. The outlet of the air passage 43 is located on the top side wall of the inflation head 42. When the inflation head 42 is inserted into the inflation port, the inflation head 42 pushes up the sealing head 7 and the air passage 43 communicates with the air hole 11, thereby completing the inflation process of the polishing bag.

[0022] Furthermore, the inflation head 42 of this utility model is externally slidably fitted with a sealing ring 8, and a sealing spring 9 is provided between the sealing ring 8 and the top surface of the base plate 4. Under the action of the sealing spring 9, the sealing ring 8 seals the outlet of the air passage 43, ensuring that the inflation head 42 can seal the air passage 43 when not in use, thus preventing gas leakage.

[0023] Even better, the bottom plate 4 of this utility model is provided with an obstacle avoidance ring groove 44 on the bottom side wall of the inflation head 42. The sealing spring 9 and the sealing ring 8 are hidden inside the obstacle avoidance ring groove 44 when the inflation head 42 is inserted into the inflation port, so as to ensure that the polishing bag can abut against the inside of the groove 41 of the bottom plate 4, thereby performing a full polishing process on the cylinder liner 3.

[0024] In this embodiment, combined with Figures 1-4 In use, the cylinder liner 3 is placed on the groove 41 of the bottom plate 4, and then the top plate 2 is pressed against the top of the cylinder liner 3. The polishing mechanism 1 is slid down until the rotating shaft is connected to the air inlet head 42. At this time, the sealing head 7 retracts under the action of the air inlet head 42, the sealing ring 8 on the air inlet head 42 moves down, and the air passage 43 of the air inlet head 42 is connected to the air hole 11, thereby inflating the polishing bag 5. Then the rotating shaft rotates to drive the polishing bag 5 to polish the cylinder liner 3, so as to polish cylinder liners 3 of different diameters.

[0025] In summary, this utility model provides a cylinder liner inner hole machining device, comprising: a top plate and a bottom plate for positioning the cylinder liner, wherein the bottom plate and the top plate cooperate to position the cylinder liner and ensure further polishing; the bottom plate is provided with an inflation head, which supplies gas to the inside of the polishing bladder, thereby ensuring the subsequent polishing process; and a polishing mechanism rotatably connected to the top plate, the polishing mechanism including a rotating shaft rotatably and slidably connected to the top plate, the bottom of the rotating shaft being provided with a polishing bladder, and the bottom of the rotating shaft being provided with an inflation port that cooperates with the inflation head. The inflation port communicates with the inside of the polishing bladder when the inflation head is inserted, and seals the polishing bladder when the inflation head is withdrawn from the inflation port, ensuring that the contact force between the polishing bladder and the inner wall of the cylinder liner is maintained during polishing, thereby polishing the cylinder liner. In summary, the technical effect of this utility model is that by setting a polishing head that can automatically adapt to different cylinder diameters, it can ensure that cylinder liners of different sizes can be polished.
