Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically, it relates to a grinding disc structure and a grinding machine tool thereof. Background Technology

[0002] Grinding discs are commonly used tools in machining to finish the surface of workpieces to achieve the required smoothness and precision.

[0003] A double-sided grinding machine with the publication number CN212095877U discloses an upper grinding disc mechanism, comprising a main shaft and an upper grinding disc. The upper grinding disc is floatingly mounted on the lower end of the main shaft. A positioning mechanism is provided between the upper grinding disc and the main shaft, located above the upper grinding disc and including a positioning sleeve and a telescopic airbag. The positioning sleeve is fitted onto the main shaft with a clearance fit and is fixed to the upper grinding disc. The telescopic airbag is fitted onto the main shaft, with its upper end fixedly connected to the main shaft and its lower end slidingly fitted to the main shaft. The lower end of the telescopic airbag is rigidly fitted to the positioning sleeve. This double-sided grinding machine adds a grinding function with a fixed upper grinding disc. Compared to the current processing methods using both surface grinders and double-sided grinding machines, the finished parts achieve the high precision of double-sided grinding machine processing. It also reduces the turnaround time of the two processes, saves one loading / unloading time, shortens the part processing cycle, and improves part processing efficiency.

[0004] However, the aforementioned patent also has the following problems: A large amount of debris is generated during the grinding process. This debris mainly consists of tiny particles ground off the workpiece surface. If not cleaned promptly, they will accumulate between the grinding disc and the workpiece, and even adhere to other parts of the device. This not only leads to secondary contamination of the workpiece surface, affecting the final processing quality, but also increases the difficulty and cost of subsequent cleaning of the workpiece and the device itself. During the high-speed rotation and close contact grinding process, a large amount of heat is generated between the grinding disc and the workpiece due to friction and compression. If the heat cannot be dissipated in time, the temperature of the grinding disc and the workpiece will rise, thus affecting their physical properties and grinding effect. Simultaneously, high temperatures may accelerate wear between the grinding disc and the workpiece, shortening their service life.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

The guide tube 40 is placed at the inner bottom of the grinding machine body 10. Activating the hydraulic cylinder 27 drives the hydraulic push rod 26 downwards, adjusting the height of the upper grinding disc 23 and the distance between the upper grinding disc 23 and the gear ring 16.

[0040] In summary, the structure of the grinding machine body 10, upper grinding disc 23, hydraulic push rod 26, hydraulic cylinder 27 and guide tube 40 allows for height adjustment of the device, facilitating the processing of workpieces of different sizes and optimizing the user experience.

[0041] Working principle: The grinding base 11 is rectangular and serves as the supporting foundation for the entire grinding machine. The cleaning structure includes a cleaning section and a protective section. The cleaning section collects and processes the debris generated during the grinding process through components such as the gear ring 16, the conical guide trough 21, the first guide box 39, and the collection box 41. The debris is guided into the first guide box 39 through the conical guide trough 21, and then discharged through the collection box 41 and the guide pipe 40. The protective section shields and protects the grinding area through components such as the first snap-fit ​​ring groove 13, the first protective ring plate 15, the first snap-fit ​​rod 14, the second protective ring plate 28, the telescopic pipe 29, and the third protective ring plate 30 to prevent debris from splashing. The grinding disc includes components such as the sun gear 17, the first grinding disc 18, the planetary gear 19, and the second grinding disc 20. Servo motor 12 drives sun gear 17 to rotate. Through the meshing of sun gear 17, planetary gear 19, and gear ring 16, the first grinding disc 18 and the second grinding disc 20 are rotated to grind the workpiece. The grinding machine body 10 serves as the main structure of the entire equipment. A hydraulic cylinder 27 and a hydraulic push rod 26 are fixedly installed on its top. The hydraulic cylinder 27 adjusts the height of the upper grinding disc 23 by driving the telescopic inner rod of the hydraulic push rod 26, thereby adjusting the distance between the upper grinding disc 23 and the gear ring 16 (i.e., the first grinding disc 18 and the second grinding disc 20) to accommodate workpieces of different sizes. The bottom of the upper grinding disc 23 is provided with a grinding surface 24 and a guide groove 25. The grinding surface 24 is used to cooperate with the lower grinding disc (the first grinding disc 18 and the second grinding disc 20) to grind the workpiece; the guide groove 25 is used to discharge the debris and heat generated during the grinding process. A guide pipe 40 is placed on the inner bottom of the body 10 to receive the debris discharged from the collection box 41. The user can move and position the entire grinding machine by holding the handles 38 on both sides of the grinding base 11. During the grinding process, the user first adjusts the height of the upper grinding disc 23 according to the size of the workpiece by using the hydraulic cylinder 27 and the hydraulic push rod 26, starts the servo motor 12, drives the sun gear 17 to rotate, and then drives the first grinding disc 18 and the second grinding disc 20 to rotate. The user places the workpiece in the grinding area, and grinds the workpiece by cooperating with the upper grinding disc 23 and the lower grinding disc. The debris generated during the grinding process is collected and processed by components such as the conical guide trough plate 21, the first guide box 39 and the collection box 41, and finally discharged through the guide pipe 40. The protective components shield and protect the grinding area throughout the grinding process to ensure operational safety.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
