[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0020] First, combine Figures 1 to 3 The roller ultra-finishing grinding device according to the embodiment of the utility model is widely used in industrial manufacturing and other scenes such as precision mechanical parts processing with high-precision grinding and polishing. In this embodiment, the grinding roller is taken as an example for description.

[0021] like Figures 1 to 3 As shown, the roller ultra-finishing grinding equipment of the embodiment of the utility model is used for grinding the roller to be processed at a processing station, and comprises a loading component 1, a grinding component 2 and a unloading component 3.

[0022] Specifically, Figures 1 to 3As shown, the loading assembly 1 moves the roller to be processed from the material source to the loading station 11 to ensure that the roller can smoothly enter the grinding process. The loading station 11 is located on one side of the processing station; the grinding assembly 2 is located at the processing station. The grinding assembly 2 includes a rough grinding processing head 21 and a fine grinding processing head 22. The roller to be processed is processed by the rough grinding processing head 21 and the fine grinding processing head 22 in turn. The two-stage grinding process (rough grinding and fine grinding) is adopted, which can quickly remove most of the material in the rough grinding stage, making the logarithmic curve of the roller more accurate, and then achieve higher precision requirements in the fine grinding stage. The grinding assembly 2 also includes a rough grinding positioning tool, a fine grinding positioning tool 4 and a clamping tool 5. The rough grinding positioning tool and the fine grinding positioning tool 4 are respectively arranged at the corresponding positions of the rough grinding processing head 21 and the fine grinding processing head 22. Through the precise positioning tool, the stability and accuracy of the grinding process are improved, and the product quality is further guaranteed. The clamping tool 5 takes out the roller to be processed from one side of the loading component 1 and transfers it to the rough grinding positioning tool and simultaneously transfers the other roller after rough grinding at the rough grinding positioning tool to the fine grinding positioning tool 4. The design of the clamping tool 5 realizes the synchronous operation of the two rollers, improves the production efficiency, and ensures the smoothness and continuity of the entire grinding process; the unloading component 3 unloads the roller processed at the fine grinding positioning tool 4 to the unloading tray, ensuring the smooth output of the product.

[0023] Preferably, the clamping tool 5 includes a double-headed bracket 51 that is symmetrical on both sides, and a clamping end is provided on each of the symmetrical sides of the double-headed bracket 51. A pair of clamping ends are arranged on one side of the double-headed bracket 51 close to the rough grinding positioning tool and the fine grinding positioning tool 4. By adopting the double-headed bracket 51 and the symmetrical clamping end design, two rollers can be processed at the same time, which improves work efficiency. The symmetrical design also ensures the stability of clamping.

[0024] Preferably, the double-headed bracket 51 is arranged on the slideway 53, and the double-headed bracket 51 moves along the extension direction of the slideway 53. The distance between the rough grinding positioning tooling and the fine grinding positioning tooling 4 is equal to the distance between the rough grinding positioning tooling and the loading point 11. The double-headed bracket 51 moves along the slideway 53, which can ensure the rapid and accurate transfer of the rollers between rough grinding and fine grinding, thereby improving the fluency and efficiency of the entire grinding process. At the same time, the equidistant design enables the double-headed bracket 51 to move in one step, and simultaneously realizes the displacement processing of the two rollers moving to the next step.

[0025] Preferably, a first distance adjustment module 54 is provided between the double-headed bracket 51 and the slide 53. The first distance adjustment module 54 drives the double-headed bracket 51 to move and changes the distance of the double-headed bracket 51 relative to the slide 53, allowing the position of the double-headed bracket 51 to be adjusted according to the size and grinding requirements of different rollers, and can also cooperate with the adjustment position of the positioning tooling, thereby increasing the flexibility and adaptability of the equipment.

[0026] Preferably, the clamping end includes a cylinder 521, a fixed claw 522 and a movable claw 523. The cylinder 521 drives the movable claw 523 to move away from or close to the fixed claw 522. The movable claw 523 and the fixed claw 522 driven by the cylinder 521 can open and close quickly as needed, which is convenient for clamping and releasing the roller and improves the level of automation.

[0027] Preferably, a second distance adjustment module 55 is provided between the clamping end and the double-head bracket 51, and the second distance adjustment module 55 drives the clamping end to move and changes the distance of the clamping end relative to the double-head bracket 51, further increasing the flexibility of the equipment and its adaptability to rollers of different specifications.

[0028] Preferably, the fixed claw 522 and the movable claw 523 are a pair of bar blocks of consistent shape, the opposite inner sides of the bar blocks are the side faces of the bar blocks, and the opposite inner sides of the bar blocks correspond to the two ends of the roller. The design of the bar blocks can better match the two ends of the roller, providing a more stable and precise clamping effect.

[0029] Preferably, the rough grinding positioning tooling and the fine grinding positioning tooling 4 are each a pair of rotating bodies, and the rotating bodies are cylindrical. During processing, the roller is located between the pair of rotating bodies. The positioning tooling using rotating bodies can simultaneously fix and rotate the rollers, provide stable support during the grinding process, and help improve grinding accuracy and efficiency.

[0030] Preferably, the rough grinding head 21 is an oilstone grinding head, which includes a worm gear and a brake disc 6. After the worm gear is adjusted, the brake disc 6 locks the worm gear. The design of the worm gear and the brake disc 6 further locks the oilstone grinding head, making it more precise and stable after adjustment, preventing position deviation due to vibration during the grinding process.

[0031] Preferably, the lapping head 22 is an abrasive belt lapping head, which can provide higher lapping accuracy and finer lapping effect, ensuring that the required accuracy requirements can be achieved in the lapping stage.

[0032] When in use, the loading component 1 first moves the roller to be processed from the raw material to the loading location 11 of the processing station. Subsequently, the clamping fixture 5 uses the double-head bracket 51 and the symmetrical clamping end to synchronously transfer the two rollers, one from the loading location 11 to the rough grinding positioning fixture, and the other from the rough grinding positioning fixture to the fine grinding positioning fixture 4. The rough grinding processing head 21 uses an oilstone grinding head to remove most of the material of the roller, making the logarithmic curve of the roller more accurate. Then the fine grinding processing head 22 uses a belt grinding head for further precise grinding to ensure that the roller meets the required accuracy requirements. During the entire grinding process, the positioning fixture of the rotating body provides stable support and rotation for the roller, ensuring the stability and accuracy of the grinding. Finally, the unloading component 3 unloads the processed roller to the unloading tray to complete the entire grinding process.

[0033] Above, refer to Figures 1 to 3 The roller superfinishing grinding equipment according to the embodiment of the utility model is described. By integrating the two-stage grinding process of rough grinding and fine grinding, it is ensured that the excess material is quickly removed in the rough grinding stage, so that the logarithmic curve of the roller is more accurate, and then precise and meticulous processing is achieved in the fine grinding stage, which significantly improves the grinding accuracy of the roller while ensuring production efficiency. At the same time, the equipment builds a fully automated production line by integrating the feeding, grinding and unloading components 3, greatly reducing the dependence on manual labor, and cooperates with the precise positioning tooling and clamping tooling 5 design to ensure accurate position control during the grinding process and improve product quality stability. The double-head bracket 51 ensures that the one-step operation of the two rollers is completed synchronously, further improving the grinding efficiency. In addition, the equipment is also highly flexible and adaptable, and can adjust the grinding process and parameters according to different processing parameters and product specification requirements to meet diversified grinding needs. Overall, this roller superfinishing grinding equipment not only achieves the improvement of grinding accuracy, but also reduces production costs and improves production efficiency.
