[0021] 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 illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Reference Figure 1-5 A grinding device for processing gears in agricultural machinery includes a frame 1, a top plate 2 fixedly connected to the top of the frame 1, and a hydraulic cylinder 3 fixedly connected to one side of the top of the top plate 2 by bolts. A bearing frame 4 is provided inside the frame 1, and a sliding rod 5 is fixedly connected to the inside of the bearing frame 4. A sliding sleeve 6 is fitted at one end of the sliding rod 5. A support frame 9 is fixedly connected to the bottom of the sliding sleeve 6, and a drive motor 11 is fixedly connected to the inside of the support frame 9 by bolts. A rotating rod 17 is rotatably connected to the bottom of the support frame 9, and the top end of the rotating rod 17 is connected to the output shaft of the drive motor 11 through a bearing sleeve through the bottom of the support frame 9. A grinding head 16 is fixedly connected to the bottom end of the rotating rod 17. An installation rod 15 is fixedly connected to the bottom of the inside of the frame 1. The output shaft of the hydraulic cylinder 3 is fixedly connected between the top plate 2 and the top of the bearing frame 4.

[0023] First, adjust the lateral position of the grinding head 16 according to the diameter of the gear to be ground. By sliding the sliding sleeve 6 on the sliding rod 5, the position of the grinding head 16 at the bottom of the support frame 9 can be precisely adjusted. After the position adjustment is completed, insert the insert rod 7 into the corresponding slots 8 on the sliding sleeve 6 and the sliding rod 5 to ensure that the sliding sleeve 6 is stable and thus fixes the position of the grinding head 16. Next, put the gear to be processed on the mounting rod 15 and position it with bolts to ensure that the gear will not be displaced during processing. Start the drive motor 11, which drives the rotating rod 17 to rotate, thereby causing the grinding head 16 to start rotating at high speed, preparing for the subsequent grinding process. Finally, the hydraulic cylinder 3 pushes the bearing frame 4 and its connected support frame 9, drive motor 11 and grinding head 16 to move down as a whole, so that the grinding head 16 can contact the gear surface and perform grinding.

[0024] Furthermore, a insertion rod 7 is provided on one side of the sliding sleeve 6, and slots 8 for use with the insertion rod 7 are provided on both the sliding sleeve 6 and the sliding rod 5. Several slots 8 are provided on the sliding rod 5. When it is necessary to adjust the lateral position of the grinding head 16, the sliding sleeve 6 is slid along the sliding rod 5 to the appropriate position. Then, through the action of the tension spring 10, the insertion rod 7 is inserted into the corresponding slots 8 on the sliding sleeve 6 and the sliding rod 5, thereby realizing the rapid fixing of the sliding sleeve 6, ensuring the stability of the sliding sleeve 6 during the grinding process, and improving the stability and adjustment accuracy of the equipment.

[0025] Furthermore, a tension spring 10 is fitted on one end of the insertion rod 7, and one end of the insertion rod 7 is elastically connected to the outer wall of the sliding sleeve 6 through the tension spring 10. The tension spring 10 provides continuous elastic force to the insertion rod 7, so that the insertion rod 7 can be tightly inserted into the slot 8 on the sliding sleeve 6 and the sliding rod 5, avoiding the situation where the insertion rod 7 is loosened due to vibration or other external forces, further enhancing the reliability of the sliding sleeve 6 fixation, and also making it easier for operators to quickly unlock and readjust the position, improving the ease of operation of the equipment.

[0026] Furthermore, nozzles 12 are fixedly connected to both sides of the support frame 9, and pump bodies 13 are fixedly connected to both sides of the frame 1 by bolts. The outlets of the two pump bodies 13 are respectively connected to one side of the two nozzles 12. After the pump body 13 is started, the external coolant or lubricant is delivered to the nozzles 12 through the telescopic hose 14, and then sprayed evenly by the nozzles 12 onto the contact position between the grinding head 16 and the gear.

[0027] Furthermore, each of the two pump bodies 13 has a telescopic hose 14 connected to its outlet, and one end of each telescopic hose 14 is connected to one side of each of the two nozzles 12. The flexibility of the telescopic hose 14 allows the nozzles 12 to adjust their position freely as the support frame 9 moves, ensuring that the coolant or lubricant can always be accurately sprayed onto the grinding area.

[0028] Furthermore, the connection between the output shaft of the hydraulic cylinder 3 and the top plate 2 is a sliding connection.

[0029] In summary:

[0030] First, the lateral position of the grinding head 16 is adjusted according to the diameter of the gear to be ground. After the sliding sleeve 6 is slid on the sliding rod 5 to the appropriate position, the tension spring 10 causes the insertion rod 7 to automatically insert into the corresponding slot 8 on the sliding sleeve 6 and the sliding rod 5, thereby quickly fixing the sliding sleeve 6 and ensuring its stability during the grinding process. Next, the gear to be processed is fitted onto the mounting rod 15 and positioned with bolts to ensure that the gear will not shift during processing. The drive motor 11 is started, which drives the rotating rod 17 to rotate, thereby causing the grinding head 16 to start rotating at high speed, preparing for the subsequent grinding process. At the same time, the pump body 13 is started, delivering external coolant or lubricant to the nozzle 12 through the telescopic hose 14, and the nozzle 12 sprays it evenly onto the contact area between the grinding head 16 and the gear to reduce the temperature during the grinding process and reduce wear. Finally, the hydraulic cylinder 3 pushes the bearing frame 4 and its connected support frame 9, drive motor 11, and grinding head 16 downwards as a whole, allowing the grinding head 16 to contact the gear surface and perform grinding. During this process, the flexibility of the telescopic hose 14 allows the nozzle 12 to freely adjust its position as the support frame 9 moves, ensuring that coolant or lubricant is always accurately sprayed onto the grinding area. The sliding sleeve 6, insert rod 7, slot 8, and tension spring 10 enable rapid and precise adjustment of the lateral position of the grinding head 16, greatly improving the flexibility and efficiency of gear processing and reducing the time and complexity of manual adjustment. The elastic connection design between the insert rod 7 and the tension spring 10 prevents the insert rod 7 from loosening due to vibration or other external forces, further enhancing the reliability of the sliding sleeve 6's fixation. It also facilitates quick unlocking and readjustment by the operator, improving the ease of operation. The combined use of the nozzles 12 on both sides of the support frame 9 with the pump body 13 and telescopic hose 14 effectively reduces the heat generated during grinding, extending the lifespan of the grinding head 16. The service life is extended, while reducing wear on the gear surface, ensuring processing quality, improving the working environment, and avoiding equipment damage or safety hazards caused by high temperatures; the flexibility of the telescopic hose 14 not only improves the cooling and lubrication effect, but also avoids the restrictions caused by pipe fixing, enhances the adaptability and ease of operation of the equipment, and further improves the overall processing efficiency; the sliding connection design between the output shaft of the hydraulic cylinder 3 and the top plate 2 ensures the smoothness and guidance of the movement process, avoids jamming or deviation caused by uneven force, improves the reliability and durability of the equipment operation, reduces maintenance costs, and ensures the accuracy of the grinding head 16 when it moves down.
