Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a cylinder inner wall polishing machine. Background Technology

[0002] A cylinder is a sealed container used to store liquids or gases. It is made of metal or plastic and has a specific volume and shape. It plays an important role in many fields. A cylinder inner wall polishing machine is a device specifically used to polish the inner wall of cylinders, such as hydraulic cylinders, air cylinders, and engine cylinders, to improve the surface smoothness, precision, and wear resistance of the inner wall.

[0003] Current cylinder inner wall polishing machines rely on workers mounting a fixed cylinder onto the machine and using a high-speed rotating polishing head inserted into the cylinder. The axial movement of the polishing head then polishes the inner wall. However, after polishing, the cylinder needs to be manually removed and moved. In mass production, frequent manual loading and unloading accumulates significant non-productive time, drastically reducing the effective operating time of the polishing equipment. Existing technology uses robotic arms with built-in sensors to automatically identify the cylinder's position and status, coordinating with the polishing machine's completion signal for seamless unloading. However, for non-standard cylinders with significant differences in shape and size, the robotic arm requires redesigned end effectors and reprogramming, resulting in insufficient flexibility.

When the polishing machine overheats locally, the motor controls the fan to dissipate heat in a directional manner. The rear battery panel supplies power to the fan and the motor, ensuring the stable operation of the heat dissipation mechanism. Attached Figure Description

[0031] 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 protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a cylinder inner wall polishing machine, comprising a machine body 1. A buffer mechanism 2 is installed on the right side of the outer wall of the machine body 1 to buffer the cylinder during feeding and prevent collision damage. A pushing mechanism 6 is installed on the top left side of the machine body 1 to push the cylinder during feeding. A heat dissipation mechanism 3 is installed on the upper rear side of the inner wall of the machine body 1 for ventilation and heat dissipation. The buffer mechanism 2 includes a slide plate 201, which is installed on the right side of the outer wall of the machine body 1. Multiple rollers 202 are equidistantly installed on adjacent sides of the outer wall of the slide plate 201. Hollow long blocks 203 are fixedly connected to the front and rear sides of the bottom of the slide plate 201. Long short plates 205 are slidably connected inside the hollow long blocks 203. Baffles 204 are fixedly connected to adjacent sides of the outer wall of the long short plates 205. Piston rods 211 are fixedly connected to the left and right sides of the outer wall of the long short plates 205. Multiple hollow... A first piston cylinder 206 is fixedly connected to the bottom right side of the inner wall of the long block 203. A spring 209 is installed on the outer wall of the first piston cylinder 206. A second piston cylinder 210 is fixedly connected to the left side of the inner wall of multiple hollow long blocks 203. A venting groove 207 is opened on the top of both the second piston cylinder 210 and the first piston cylinder 206. A circular plate 208 is fixedly connected to the outer wall of the piston rod 211. The pushing mechanism 6 includes a hydraulic push rod 601. The hydraulic push rod 601 is installed on the top left side of the machine body 1. A push plate 602 is fixedly connected to the right end of the outer wall of the hydraulic push rod 601. When the hydraulic push rod 601 is activated, it can drive the push plate 602 to push and feed the material. The middle part of the inner wall of the moving plate 303 is threadedly connected to the outer wall of the threaded column 3056. The left side of the inner wall of the moving plate 303 is slidably connected to the outer wall of the slide rod 3055. The slide rod 3055 can limit the movement trajectory of the moving plate 303.

[0033] Specifically, the grinding cylinder 7 is fitted onto the grinding and polishing machine 5 on the top left side of the machine body 1. The grinding and polishing machine 5 is started to polish the inner wall of the cylinder. After grinding is completed, the hydraulic push rod 601 installed on the top left side of the machine body 1 is activated. The hydraulic push rod 601 extends, driving the push plate 602 fixedly connected to its right end to move to the right, pushing the grinding cylinder 7 off the grinding and polishing machine 5. After being pushed off, the grinding cylinder 7 falls into the sliding plate 201 on the right side of the outer wall of the machine body 1. The cylinder slides downwards under the action of the equally spaced rollers 202. When the cylinder slides to the bottom and hits the baffle 204, the baffle 204 drives the elongated short plate 205 fixedly connected to it to move backward. The piston rod 211 on the outer wall of the elongated short plate 205 then inserts into the first piston cylinder 206. At this time, the spring 209 on the outer wall of the first piston cylinder 206 is compressed, absorbing the impact force of the cylinder impact. At the same time, the gas in the first piston cylinder 206 is discharged through the vent groove 207 at the top, realizing... When the spring 209 recovers its deformation after compression and buffering, the long short plate 205 moves forward, and the piston rod 211 on the front side inserts into the second piston cylinder 210. The second piston cylinder 210 releases excess gas through the venting groove 207, eliminating the elastic force generated by the recovery of the spring 209 and preventing the cylinder from rebounding. This avoids the problem of insufficient flexibility caused by the need to redesign the end effector and program the gripping and unloading for non-standard cylinders with large differences in shape and size. The pushing mechanism 6 includes a hydraulic push rod 601, which is installed on the top left side of the machine body 1. The right end of the outer wall of the hydraulic push rod 601 is fixedly connected to the push plate 602. When the hydraulic push rod 601 is activated, it can drive the push plate 602 to push and unload the material. The middle part of the inner wall of the moving plate 303 is threadedly connected to the outer wall of the threaded column 3056. The left side of the inner wall of the moving plate 303 is slidably connected to the outer wall of the slide rod 3055. The slide rod 3055 can limit the movement trajectory of the moving plate 303.

[0034] Reference Figure 2 , Figure 3 and Figure 6The heat dissipation mechanism 3 includes a long strip plate 301, which is installed on the upper rear side of the inner wall of the body 1. A movable plate 303 is installed at the bottom of the long strip plate 301. A battery plate 304 is fixedly connected to the rear side of the outer wall of the movable plate 303. A fan 302 is fixedly connected to the front side of the outer wall of the movable plate 303. A drive assembly 305 is installed on the rear side of the outer wall of the body 1. The drive assembly 305 includes a motor 3051, which is installed on the rear side of the outer wall of the body 1. A worm gear 3054 is fixedly connected to the output end of the motor 3051. The bottom of the long strip plate 301... A slide rod 3055 is fixedly connected to the left side. A threaded column 3056 is rotatably connected to the middle of the inner wall of the long strip plate 301. A worm wheel 3053 is meshed with the outer wall of the worm 3054. Support rods 8 are fixedly connected to the bottom of the machine body 1 near the four corners. Support feet 4 are fixedly connected to the bottom of the support rods 8. Support feet 4 can support and fix the machine body 1. A grinding and polishing machine 5 is installed on the top left side of the machine body 1. A grinding cylinder 7 is set at the right end of the outer wall of the grinding and polishing machine 5. By turning on the grinding and polishing machine 5, the grinding cylinder 7 can be ground and polished.

[0035] Specifically, after the motor 3051 is started, it drives the worm 3054 at the output end to rotate. The worm 3054 meshes with the worm wheel 3053, transmitting power to the worm wheel 3053, which in turn drives the threaded column 3056 fixedly connected to the upper part of the inner wall to rotate. The middle part of the inner wall of the moving plate 303 is threadedly connected to the outer wall of the threaded column 3056, and the left side is slidably connected to the outer wall of the slide rod 3055. When the threaded column 3056 rotates, the sliding rod 3055 limits and guides the moving plate 303, causing the moving plate 303 to move up and down along the direction of the slide rod 3055 under the drive of the threaded column 3056. The fan 302 fixedly connected to the front of the moving plate 303 moves synchronously with the moving plate 303, which can cool different parts inside the machine body 1. Heat dissipation is achieved through various means. For example, when the polishing machine 5 operates for an extended period, causing a local temperature increase, the motor 3051 controls the fan 302 to move to the corresponding high-temperature area to enhance ventilation and heat dissipation. The battery plate 304, fixedly connected to the rear of the moving plate 303, supplies power to the fan 302 and the motor 3051, ensuring the normal operation of the heat dissipation mechanism 3. Support rods 8 are fixedly connected to the bottom of the machine body 1 near the four corners, and the bottom of the support rods 8 is fixedly connected to the feet 4, which can support and fix the machine body 1. The polishing machine 5 is installed on the top left side of the machine body 1, and a polishing cylinder 7 is provided on the right end of the outer wall of the polishing machine 5. By turning on the polishing machine 5, the polishing cylinder 7 can be polished.

[0036] Reference Figure 1 and Figure 6A fixed support plate 3052 is fixedly connected to the rear side of the outer wall of the machine body 1. The top of the fixed support plate 3052 is fixedly connected to the bottom of the motor 3051. The fixed support plate 3052 can support and fix the motor 3051. The outer wall of the long strip plate 301 is fixedly connected to the inner wall of the machine body 1. The inner wall of the worm gear 3053 is fixedly connected to the upper middle part of the outer wall of the threaded column 3056. The threaded column 3056 can be driven to rotate by the meshing of the worm gear 3053 and the worm 3054.

[0037] Specifically, a fixed support plate 3052 is fixedly connected to the rear side of the outer wall of the machine body 1. The top of the fixed support plate 3052 is fixedly connected to the bottom of the motor 3051. The fixed support plate 3052 can support and fix the motor 3051. The outer wall of the long strip plate 301 is fixedly connected to the inner wall of the machine body 1. The inner wall of the worm gear 3053 is fixedly connected to the upper middle part of the outer wall of the threaded column 3056. The threaded column 3056 can be driven to rotate by the meshing of the worm gear 3053 and the worm 3054.

[0038] Working principle: The grinding cylinder 7 is fitted onto the grinding and polishing machine 5 on the top left side of the machine body 1. The grinding and polishing machine 5 is started to polish the inner wall of the cylinder. After grinding is completed, the hydraulic push rod 601 installed on the top left side of the machine body 1 is activated. The hydraulic push rod 601 extends, driving the push plate 602 fixedly connected to its right end to move to the right, pushing the grinding cylinder 7 off the grinding and polishing machine 5. After being pushed off, the grinding cylinder 7 falls into the slide plate 201 on the right side of the outer wall of the machine body 1. Under the action of the rollers 202 arranged at equal intervals on the slide plate 201, it slides downward. When the cylinder slides to the bottom and hits the baffle 204, the baffle 204 drives the long short plate 205 fixedly connected to it to move backward. The outer wall of the long short plate 205... Piston rod 211 is then inserted into first piston cylinder 206. At this time, spring 209 on the outer wall of first piston cylinder 206 is compressed to absorb the impact force of cylinder impact. At the same time, gas in first piston cylinder 206 is discharged through vent groove 207 at the top, realizing compression buffering and force relief. When spring 209 returns to its deformation, long short plate 205 moves forward, and piston rod 211 on the front side is inserted into second piston cylinder 210. Second piston cylinder 210 releases excess gas through vent groove 207, eliminating the elastic force generated by spring 209 returning to its deformation, avoiding cylinder rebound, and avoiding the problem of insufficient flexibility due to the need for redesigning end effector and programming gripping and unloading for non-standard cylinders with large differences in shape and size.

[0039] After the motor 3051 is started, it drives the worm 3054 at the output end to rotate. The worm 3054 meshes with the worm wheel 3053, transmitting power to the worm wheel 3053, which in turn drives the threaded column 3056 fixedly connected to the upper part of the inner wall to rotate. The middle part of the inner wall of the moving plate 303 is threadedly connected to the outer wall of the threaded column 3056, and the left side is slidably connected to the outer wall of the slide rod 3055. When the threaded column 3056 rotates, the sliding rod 3055 limits and guides the moving plate 303, causing the moving plate 303 to move along the slide rod 3055. Driven by the threaded column 3056, the five directions move up and down. The fan 302, which is fixedly connected to the front of the moving plate 303, moves synchronously with the moving plate 303, which can dissipate heat from different positions inside the machine body 1. For example, when the polishing machine 5 works for a long time and the local temperature rises, the motor 3051 controls the fan 302 to move to the corresponding high temperature area to enhance ventilation and heat dissipation. The battery plate 304, which is fixedly connected to the rear of the moving plate 303, supplies power to the fan 302 and the motor 3051 to ensure that the heat dissipation mechanism 3 can operate normally.
