Description

Technical Field

With the rapid development of modern social economy, the increase in the number of high-precision and high-hardness mechanical parts, and the development of precision casting and precision forging technology, the application of grinding machines in production and processing is becoming more and more extensive. A grinding machine is generally composed of a cast iron bed as the basic part, a worktable, a head fixing frame that supports and drives the workpiece to rotate, a tail fixing frame, a mounting seat for mounting a grinding wheel, a lateral feed mechanism that controls the size of the grinding workpiece, and electrical and hydraulic devices that control the movement of the moving parts of the machine tool. In order to protect the grinding wheel and prevent the grinding wheel from throwing grinding fluid and grinding debris to the outside during grinding, a cover is also installed on the grinding wheel.

[0036] The present invention also provides a grinding method for automobile wheel axles, using a shaft grinding device, and the specific steps are: First, use the head fixing frame 12 and the tail fixing frame 13 to clamp the shaft to be processed on the bed 1 so that the shaft is in the processing position. Then the grinding wheel 24 of the grinding assembly 2 rotates to grind the shaft. During the grinding process, the driving assembly 8 drives the driving rod 31 and the driven rod 4 to drive the cleaning scraper 7 to swing back and forth in the cover 25. At the same time, the main push rod 33 will push the cleaning scraper 7 to always contact the discharge slope 251 during the swinging of the driving rod 31, thereby effectively scraping off the grinding fluid and debris on the discharge slope 251, and discharge it into the collection assembly 9 through the sump 14 on the bed 1. After the shaft is processed, the equipment stops working.

[0037] Working principle: When in use, the shaft to be processed is placed between the head fixing frame 12 and the tail fixing frame 13, so that the head fixing frame 12 and the tail fixing frame 13 are clamped at both ends of the shaft, thereby clamping the shaft on the bed 1. When grinding begins, the head fixing frame 12 is driven by the motor to drive the shaft to rotate between the head fixing frame 12 and the tail fixing frame 13. At the same time, the grinding wheel 24 of the grinding assembly 2 rotates to grind the rotating shaft. At the same time, the nozzle 28 on the grinding assembly 2 sprays grinding fluid onto the grinding wheel 24 and the shaft. During the grinding process, the grinding fluid will wash away the debris ground off the shaft, among which part of the grinding fluid will fall into the sump 14 with the debris. The cleaning fluid flows to the collecting assembly 9, and the rotating grinding wheel 24 throws another part of the grinding fluid mixed with the debris into the cover 25. This part of the grinding fluid and the debris will fall on the discharge slope 251 of the cover 25. At this time, the cleaning mechanism 3 is started, and the driving motor 22 drives the driving disc 82 to rotate. The rotating driving disc 82 slides up and down in the guide chute 311 through the eccentric shaft 821, driving the driving rod 31 installed on the fixed shaft 26 to swing back and forth, so that the driving rod 31 and the main push rod 33 and the auxiliary push rod 41 in the driven rod 4 drive the cleaning scraper 7 to move back and forth on the discharge slope 251, scraping off the grinding fluid and debris on the discharge slope 251, thereby ensuring the cleanliness of the inside of the cover 25. During this process, the transmission gear 321 rolls along the sector gear ring 27, thereby driving the driven gear 322 to rotate in the driving rod 31. When the driving rod 31 swings toward the lower end of the discharge slope 251, the transmission gear 321 drives the driven gear 322 to rotate forward. The rotating driven gear 322 drives the main push rod 33 to extend from the driving rod 31 through the driving rack 331, so that the cleaning scraper 7 moves from the upper end of the discharge slope 251 to the lower end of the discharge slope 251, always keeping in contact with the discharge slope The cleaning scraper 7 scrapes the grinding fluid and debris on the discharge slope 251 out of the housing 25. When the driving rod 31 swings toward the upper end of the discharge slope 251, the transmission gear 321 drives the driven gear 322 to rotate in the opposite direction. When the driven gear 322 rotates in the opposite direction, the rotating driven gear 322 drives the extended main push rod 33 to be stored back in the driving rod 31 through the driving rack 331, so that the cleaning scraper 7 moves from the lower end of the discharge slope 251 to the upper end of the discharge slope 251. , and it always conflicts with the discharge slope 251. When the main push rod 33 moves, the main push rod 33 drives the auxiliary push rod 41 to move synchronously through the cleaning scraper 7. When the main push rod 33 telescopes, the auxiliary push rod 41 will also move accordingly in the driven rod 4. When the main push rod 33 and the auxiliary push rod 41 telescope, the limit block 5 will slide a corresponding distance in the sliding groove 6. The setting of the limit block 5 prevents the main push rod 33 or the auxiliary push rod 41 from moving excessively, thereby ensuring the normal operation of the cleaning mechanism 3 and the cleaned The grinding fluid and debris scraped off by the cleaning scraper 7 will fall into the water collection tank 14 below, mix with the grinding fluid in the water collection tank 14, and be discharged together into the filter plate 92 in the box mouth of the collection box 91. The filter plate 92 filters out the debris in the grinding fluid, so that the grinding fluid falls into the collection box 91, while the debris remains on the filter plate 92, thereby realizing the separation of the grinding fluid and debris, facilitating the recovery of the grinding fluid and debris, and improving the collection efficiency of the grinding fluid and debris. After the shaft is processed, the equipment stops working.
