It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] See also Figure 1-4The present invention provides a technical solution: a polishing machine for manufacturing diesel engine cylinder heads, comprising a workbench 1, the bottom surface of which is fixedly mounted with support legs evenly distributed at the four corners of the bottom surface of the workbench 1. The support legs can be fixed by bolts or welding, which not only ensures the stability of the equipment but also facilitates maintenance and movement. A mounting bracket 2 is fixedly mounted on the top surface of the workbench 1. The mounting bracket 2 is made of carbon steel, which has high strength and good corrosion resistance, suitable for withstanding heavy loads and long-term use. A hydraulic cylinder 3 is fixedly mounted on the surface of the mounting bracket 2, and a mounting seat 4 is mounted on the output end of the hydraulic cylinder 3. A motor 5 is fixedly mounted on the top surface of the mounting seat 4. The motor 5 drives a belt, which is connected to a driven pulley 8, driving a rotating shaft 6 to rotate, thereby rotating a polishing wheel 7 to perform the polishing operation. A rotating shaft 6 is provided through the top surface of the mounting seat 4. The rotating shaft 6 is rotatably connected to the mounting seat 4, and can be connected by bearings or sliding sleeves. This connection method can provide stable and smooth rotation performance, reduce friction and wear, and extend the service life of the equipment. A polishing wheel 7 is fixedly mounted on the bottom end of the rotating shaft 6 , and a driven pulley 8 is fixedly mounted on the top end thereof. The driven pulley 8 drives the rotating shaft 6 to rotate, effectively transmitting the power of the motor 5 to the polishing wheel 7 .

[0025] See also Figure 1-4 A rotating table 9 is installed on the top surface of the workbench 1, and a slide rail 10 is fixedly installed on the top surface of the rotating table 9. A slider 11 is slidably connected to the surface of the slide rail 10, and a clamp 12 is fixedly installed on the top surface of the slider 11. The design of the clamp 12 allows the diesel engine cylinder head to be firmly locked and remain stable during the polishing process. A driving mechanism is provided under the rotating table 9, which can drive the rotating table 9 to rotate so that the diesel engine cylinder head can be evenly polished with the support of the clamp 12. A vertical block A13 and a vertical block B14 are fixedly installed on the top surface of the rotating table 9. A threaded rod 15 is rotatably connected inside the vertical block A13, and a long rod 16 is fixedly installed on the back of the vertical block B14. A connecting block 17 is fixedly installed on the side of the clamp 12. A thread is provided inside the connecting block 17, which engages with the threaded rod 15. The threaded rod 15 can be rotated by a manual or automatic mechanism to drive the connecting block 17 to move, driving the clamp 12 to slide along the slider 11 and the slide rail 10, so that the diesel engine cylinder head can be easily extended after polishing, which is convenient for transportation and lifting.

[0026] Example 2

[0027] See also Figure 2-3The surface of the workbench 1 is provided with an extension mechanism, which includes a mounting block 18. The mounting block 18 is fixedly mounted on the surface of the workbench 1, and the side of the mounting block 18 is rotatably connected to a rotating rod 19. A vertical plate 20 is fixedly mounted on one end of the rotating rod 19, and a limit rod 21 is provided through the side of the vertical plate 20, and the limit rod 21 is slidably connected to the vertical plate 20. A pull block 22 is fixedly mounted on one end of the limit rod 21, and a tension spring 23 is sleeved on the surface of the limit rod 21. One end of the tension spring 23 is fixedly connected to the pull block 22, and the other end of the tension spring 23 is fixedly connected to the vertical plate 20, providing tension so that the limit rod 21 can be stably inserted into or withdrawn from the socket 26, maintaining or releasing the limit of the support plate 24. An anti-slip pad 25 is fixedly mounted on the surface of the support plate 24. The material of the anti-slip pad 25 is natural rubber, which provides sufficient friction to prevent tools and objects from sliding during operation. When the support plate 24 is not needed, the limit rod 21 can be pulled by the pull block 22 to allow the limit rod 21 to leave the insertion hole 26, thereby folding the support plate 24, saving space and making the device more compact when not in use.

[0028] Working principle: Place the diesel engine cylinder head on the fixture 12 and lock it, then drive the mounting seat 4 downward through the hydraulic cylinder 3 until the polishing wheel 7 drops to the inner wall of the diesel engine cylinder head, and then drive the belt to move through the motor 5. The belt can then drive the driven pulley 8 to rotate, and the driven pulley 8 can then drive the rotating shaft 6 to rotate, thereby rotating the polishing wheel 7 for polishing. A driving mechanism is provided under the rotating table 9, which can drive the rotating table 9 to rotate. The rotating table 9 can then drive the diesel engine cylinder head to rotate through the fixture 12, thereby evenly polishing the inner wall. At the same time, after polishing is completed, the staff can twist the threaded rod 15 to rotate. At this time, since there is a thread in the connecting block 17, the threaded rod 1 At this time, the connecting block 17 can be driven to move, and the connecting block 17 can then drive the clamp 12 to move outward. At the same time, the clamp 12 slides through the long rod 16 and the slider 11, so that the diesel engine cylinder head can be extended, thereby facilitating the handling and lifting operation and improving the handling and lifting efficiency. The utility model uses the hydraulic cylinder 3 to drive the mounting base 4 to move downward and the motor 5 to drive the belt to rotate the polishing wheel 7. The automated design reduces the need for manual operation and improves the efficiency of the polishing operation. The mechanism of the threaded rod 15 and the connecting block 17 is designed to easily release and move the cylinder head, simplifying the process of removing the part after polishing is completed. This design reduces the labor intensity of the staff and reduces the complexity of the operation, making it easy to operate and maintain. The clamp 12 in the design can easily extend the diesel engine cylinder head through the sliding mechanism of the long rod 16 and the slider 11, which is convenient for handling and lifting operations, reduces the physical labor required for moving the workpiece, and improves the efficiency and safety of handling and lifting. The provided support plate 24 can be used to conveniently place tools and other items. When in use, it is only necessary to rotate the support plate 24 to make the support plate 24 flush with the workbench 1, and then due to the tension of the tension spring 23, the tension spring 23 can pull the pull block 22 to move, and the pull block 22 can then drive the limit rod 21 to insert into the socket 26, then the angle of the support plate 24 can be limited, and the support plate 24 is unfolded. When not in use, it is only necessary to pull the limit rod 21 through the pull block 22 to make the limit rod 21 leaves the socket 26, then the limit of the support plate 24 can be released, thereby folding the support plate 24. In the utility model, the design of the support plate 24 allows the user to easily adjust the angle of the support plate 24 to be flush with the workbench 1 as needed, making it more convenient to place tools and items and improving work efficiency. The design of the limit rod 21 can effectively limit the angle of the support plate 24 during use, ensuring that tools and items are stable and do not slide, avoiding accidents caused by tilting or moving, and enhancing the safety of the working environment. At the same time, when the support plate 24 is not in use, the design of the pull block 22 makes it possible to easily release the limit rod 21, thereby quickly folding the support plate 24. This feature saves storage space and makes the equipment more compact when not in use.
