[0002] Large marine engine bearings are one of the most critical components in a ship's propulsion system. They are primarily used to support and lubricate the crankshaft or other rotating shafts, ensuring their smooth and efficient operation. Bearings are typically installed in bearing housings inside the engine. They are generally machined using a precision boring machine, which uses a high-speed rotating boring bar to cut the bearing.

[0003] Due to the special shape of the bearing bush and the large size of the bearing bush used in marine generators, installation often requires the use of cranes or other equipment to install the bearing bush with a precision boring machine so that the precision boring tool can process the bearing bush. However, the back-and-forth loading and unloading operation of the bearing bush using a crane is complicated and prone to positional deviation. The lack of dedicated matching equipment makes it inconvenient to load and unload the bearing bush and difficult to meet the usage requirements. Utility Model Content

[0021] Please see Figures 1-5 An automatic loading and unloading device for a precision boring machine for ultra-large diameter bearings of marine engines includes a precision boring machine body 1, and a material picking mechanism 2 and a drive mechanism 3 are provided on one side of the precision boring machine body 1.

[0022] The material handling mechanism 2 includes a first base plate 201 and a second base plate 204. Two first linear modules 202 are fixed to the top of the first base plate 201. A first support platform 203 is fixed to the surface of the moving part of the first linear module 202. There are two second base plates 204. A second support platform 205 is fixed to the top of the second base plate 204. Extension plates 206 are fixed to both sides of the surface of the second support platform 205. A second linear module 217 is fixed to the top of the extension plate 206. A first U-shaped frame 207 is fixed to the surface of the moving part of the second linear module 217. A first hydraulic cylinder 208 is fixed to the surface of the first U-shaped frame 207. One end of the first hydraulic cylinder 208 passes through the first U-shaped frame 207 and is fixed with a first clamping plate 209. The surfaces of the first support platform 203 and the second support platform 205 are both designed with a V-shaped structure.

[0023] One side of the second support platform 205 is used to place the bearings to be processed, while the other side of the second support platform 205 is used to store the processed bearings. Since both the first support platform 203 and the second support platform 205 have a V-shaped design, the bearings can be automatically positioned on their surfaces. After each bearing is placed on the second support platform 205 surface in a predetermined position with a certain interval between adjacent bearings, the first base plate 201 can be moved by the drive mechanism 3, aligning the first support platform 203 with the second support platform 205 on which the bearings are placed. Then, the second linear module 217 moves the first U-shaped frame 207, allowing the first clamping plate 209 to move to the position of the outermost bearing. At this time, the first hydraulic cylinders 208 on both sides are activated, allowing the first clamping plates 209 to clamp the bearings. The movement of the second linear module 217 allows the first clamping plates 209 to lift the bearings from the second support platform 205. 05 The surface is pushed onto the surface of the first support platform 203. Then, the first hydraulic cylinder 208 and the second linear module 217 are reset. At this time, the drive mechanism 3 drives the first base plate 201 to move to one side of the precision boring machine body 1. The first linear module 202 drives the first support platform 203 to move toward the direction of the precision boring machine body 1, so that the boring tool on the surface of the precision boring machine body 1 can contact the bearing surface for processing. After processing, the first linear module 202 drives the first support platform 203 to move away from the precision boring machine body 1. Then, the drive mechanism 3 drives the first base plate 201 to move to the side of the second base plate 204 on the surface for storing the processed bearing. The second linear module 217 on the surface of the second support platform 205 on this side cooperates with the first hydraulic cylinder 208 so that the bearing on the surface of the first support platform 203 can be clamped onto the surface of the second support platform 205, thereby completing the automatic loading and unloading of the bearing.

[0024] Furthermore, a plurality of first guide rails 215 are fixed to the top of the first base plate 201, and a first slider 216 is slidably connected to the surface of the first guide rail 215. The top of the first slider 216 is fixedly connected to the bottom of the first support platform 203.

[0025] The first support platform 203 can drive the first slider 216 to slide on the surface of the first guide rail 215, so that the weight of the bearing can be transferred to the first guide rail 215 and the first base plate 201 through the first support platform 203 and the first slider 216, avoiding the first linear module 202 bearing the entire weight of the first support platform 203 and the bearing, and making the bearing easier to be driven by the moving parts of the first linear module 202.

[0026] Furthermore, a second U-shaped frame 218 is fixed to the top of the first base plate 201, a second hydraulic cylinder 212 is fixed to the surface of the second U-shaped frame 218, and one end of the second hydraulic cylinder 212 passes through the second U-shaped frame 218 and is fixed with a second clamping plate 213.

[0027] After the bearing bush is pushed onto the surface of the first support platform 203 by the first clamping plate 209, the first support platform 203 moves to a position close to the body 1 of the precision boring machine. At this time, the second hydraulic cylinders 212 on both sides are activated, so that the bearing bush can be clamped and fixed by the second clamping plate 213, thereby preventing the bearing bush from moving when the boring tool cuts.

[0028] Furthermore, the shape of the second clamping plate 213 is adapted to the shape of the bearing bush, and the first clamping plate 209 has a U-shaped structure design;

[0029] By designing the shape of the second clamping plate 213, the bearing bush can be properly clamped and fixed when the two second clamping plates 213 move towards each other, without moving upward. By setting the first clamping plate 209 into a U-shape, it is ensured that the two sides of the first clamping plate 209 can contact the surface of the bearing bush, so that the first clamping plate 209 can normally drive the bearing bush to move.

[0030] Furthermore, multiple U-shaped plates 210 are fixed to the top of the second support platform 205, and rotating rollers 211 are rotatably connected to the surface of the U-shaped plates 210.

[0031] When the bearing bush is placed on the surface of the second support platform 205, the bottom of the bearing bush can come into contact with the surface of the rotating roller 211. When the bearing bush is pushed by the first clamping plate 209, the rotating roller 211 can rotate, thereby reducing the friction force on the bearing bush and making it easier to push the bearing bush.

[0032] Furthermore, the drive mechanism 3 includes a support base 301, two second guide rails 302 are fixed on the surface of the support base 301, a plurality of second sliders 303 are slidably connected to the surface of the second guide rails 302, a movable platform 304 is fixed on the top of the second sliders 303, a reduction motor 305 is fixed on the surface of the movable platform 304, a gear 306 is fixed on the output shaft of the reduction motor 305, a rack 307 is fixed on the top of the support base 301, the gear 306 meshes with the rack 307, and the top of the movable platform 304 is fixedly connected to the bottom of the first base plate 201.

[0033] When the geared motor 305 starts, it can drive the gear 306 to rotate. The meshing of the gear 306 and the rack 307 will allow the movable table 304 to drive the second slider 303 to slide on the surface of the second guide rail 302. This will allow the movable table 304 to drive the first base plate 201 to change position, so that the first base plate 201 can move to the side of the second base plate 204 used for loading or unloading.

[0034] Furthermore, multiple guide rods 214 slide through the surface of the second U-shaped frame 218, with one end of each guide rod 214 fixedly connected to the surface of the second clamping plate 213.

[0035] When the second clamping plate 213 moves, the guide rod 214 slides on the surface of the second U-shaped frame 218, thereby providing a guiding effect for the second clamping plate 213 and enabling it to move in a straight line.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
