Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal casting processing technology, and in particular relates to a metal casting grinding machine with a tensioning structure. Background Technology
[0002] Metal castings are shaped metal products obtained by casting liquid metal into a specific mold through casting processes, followed by cooling, solidification, and cleaning. They utilize various metal materials such as iron, aluminum, and copper, and employ processes such as sand casting, die casting, and investment casting, making them an indispensable basic component in modern manufacturing.
[0003] When grinding metal castings, the clamping structure of the metal casting grinding machine uses a belt for transmission. However, the belt will inevitably become loose or have abnormal tension due to material creep and fluctuations in working conditions during long-term operation. Therefore, we need to design a metal casting grinding machine with a tensioning structure. The belt tensioning structure can adjust the belt tension, avoid slippage due to excessive looseness and damage due to excessive tightness, maintain the optimal friction transmission state, compensate for the length deformation of the belt caused by long-term use and changes in working conditions, and ensure stable transmission operation.

[0022] In the following description, embodiments of the present invention, a metal casting grinding machine with a tensioning structure, will be described with reference to the accompanying drawings.
[0023] Figure 1-5 This invention illustrates a metal casting grinding machine with a tensioning structure according to an embodiment of the present invention. It includes a grinding machine housing 1, a grinding structure 2 mounted on the rear side of the inner cavity of the grinding machine housing 1, a moving structure 3 mounted on the front side of the inner cavity of the grinding machine housing 1, a transmission assembly 4 slidably connected to the top of the moving structure 3, a belt 5 driven by two pulleys within the inner cavity of the transmission assembly 4, a clamping assembly 6 fixedly connected to the surface of the belt 5 by two symmetrical connecting blocks, a rectangular shell 7 fixedly connected to the front side of the inner cavity of the grinding machine housing 1, and a fixed cover 8 fixedly connected to the surface of the rectangular shell 7. The rectangular shell 7, with its regular cavity structure, provides a stable installation space for the fixed cover 8. By limiting the displacement of the fixed cover 8, the tension transmission path is ensured to be precise, improving the reliability of belt 5 tension control. A fixed cover 8 is provided on the front side of the inner cavity of the grinding machine housing 1. A threaded rod 9 is rotatably connected to the left side of the inner cavity of the fixed cover 8. A connecting plate 13 is provided on the outer side of the fixed cover 8. A sliding rod 10 is fixedly connected to the right side of the inner cavity of the fixed cover 8. The surface of the threaded rod 9 is threaded. A threaded block 11 is provided, and a sliding block 12 is slidably connected to the surface of the slide rod 10. The threaded block 11 and the sliding block 12 extend to the outside of the fixed cover 8 and are fixedly connected to the connecting plate 13. Through the cooperation of the slide rod 10 and the sliding block 12, the sliding block 12 drives the connecting plate 13 to slide on the surface of the slide rod 10. The slide rod 10 guides the sliding block 12, ensuring that the connecting plate 13 will not deviate during sliding, thus improving the stability of the connecting plate 13. The bottom of the inner cavity of the fixed cover 8 is installed with... There is a motor 15, and a connecting block 14 is fixedly connected to the bottom of the inner cavity of the fixed cover 8. The motor 15 is installed at the bottom of the connecting block 14. The output shaft of the motor 15 is fixedly connected to the threaded rod 9. Two symmetrical tension rollers 17 are rolledly connected to the surface of the clamping assembly 6. An arc plate 16 is fixedly connected to the rear side of the connecting plate 13. The rear side of 16 is rotatably connected to the two tension rollers 17. A rectangular groove is opened on the rear side of the fixed cover 8 for the threaded block 11 and the sliding block 12 to slide. The rear side of the clamping assembly 6 clamps a metal casting.
[0024] Working Principle: When grinding metal castings, the integrated frame of the grinding machine housing 1 first provides the mounting foundation and protection for each functional module. After starting the equipment, the grinding structure 2, as the grinding execution unit, is driven by power to prepare for surface processing of the casting. The moving structure 3, in conjunction with the clamping assembly 4, can adjust the position and posture of the casting as needed to ensure that the grinding area is accurately aligned with the grinding structure. In the transmission link, the belt 5 undertakes the task of power transmission, such as connecting the drive source and the grinding spindle. To ensure transmission stability, the tension control system intervenes synchronously. The motor 15, as the power source, drives the threaded rod 9 to rotate. Because the threaded block 11 is threadedly engaged with the threaded rod and is restricted by the guide structure composed of the sliding rod 10 and the sliding block 12, the sliding block slides along the sliding rod to avoid deflection. The threaded block will move axially along the threaded rod, thereby driving the connecting plate 1. 3. The arc plate 16 is linked with the tension roller 17 installed on the arc plate 16. The contact position and pressure between the tension roller 17 and the belt 5 change with the displacement of the arc plate. When the belt becomes loose due to long-term use and fluctuations in working conditions, the motor rotates forward to drive the threaded rod, causing the tension roller to push the belt away from the pulley, increasing the belt tension. If it is necessary to reduce the tension, the motor rotates in the reverse direction to move the tension roller back. Through this dynamic adjustment, the belt is always kept in the best friction transmission state, compensating for belt length deformation, avoiding slippage due to excessive looseness and damage due to excessive tightness, and ensuring stable transmission of grinding power. At the same time, the rectangular shell 7 provides rigid installation space for the fixed cover 8 and the internal tensioning components, restricting the displacement of the fixed cover and ensuring accurate transmission path of tension force. The connecting block 14 firmly supports the motor 15, improving structural reliability. Finally, with the cooperation of all components, stable clamping and precise grinding of metal castings are achieved.
[0025] In summary, this metal casting grinding machine with a tensioning structure grinds metal castings through the grinding structure 2, the moving structure 3, and the transmission component 4. By using the threaded rod 9, the threaded block 11, and the arc plate 16 in conjunction, the arc plate 16 drives the tensioning roller 17 to adjust the tension of the belt 5. This achieves the purpose of adjusting the belt tension according to different needs, ensuring grinding accuracy, and extending the service life of the transmission components.
