Description

Technical Field

[0001] The invention belongs to the technical field related to bearing ring production and processing equipment, and specifically relates to a grinding machine for high-precision bearing ring grinding. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or more raceways. The production steps of the bearing ring are: forging, heat treatment, monitoring of the grinding process, and identification management. When the bearing ring is being ground, it will use a grinding machine tool; a grinding machine tool is a mechanical processing equipment that removes materials. Furthermore, it is a machine tool that uses a grinding tool to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other grinding tools and free abrasives such as oilstones and abrasive belts for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers.

[0003] At present, when a grinding machine is put into the grinding work of a bearing ring, when the grinding wheel of the grinding machine is grinding the outer wall of the bearing ring, debris will be adhered to the surface of the grinding wheel.

[0044] When in use, the staff first puts the bearing ring on the outer wall of the first top column 1, and then the staff operates the external controller, and the external controller will control the electric cylinder 15 to contract, so that the second support seat 7 slides on the outer walls of the two guide rails 6 toward the first support seat 3, so that the second top column 18 and the first top column 1 can clamp the bearing ring, and then the staff operates the external controller again, and the external controller will control the second drive motor 29 to work. When the second drive motor 29 is working, it will drive the second top column 18 to rotate through the coupling 26, thereby driving the bearing ring to rotate, and then the staff operates the external controller again, and the external controller will control the first servo motor 10 and the second servo motor 13 to work in turn, so that the first ball screw module 11 and the second ball screw module 12 work in turn, completing the grinding mechanism. The position adjustment work will make the grinding wheel 22 of the grinding mechanism close to the outer wall of the rotating bearing ring. At this time, the staff will operate the external controller again, and the external controller will control the first driving motor 24 to work. When the first driving motor 24 is working, it will drive the first disc 31 to rotate, thereby driving the toggle cylinder 40 to rotate, so that the toggle cylinder 40 will slide upward inside the limiting groove 39 and toggle the swing rod 41 to swing forward. At the same time, the anti-slip slider 38 will also slide downward inside the slide groove frame 37, and push the slide groove frame 37, the swing rod 41, and the grinding assembly to move forward, completing the fine adjustment of the position of the grinding assembly. When the lower side of the front end surface of the grinding wheel 22 contacts the outer wall of the rotating bearing ring, the staff will operate the external controller again, and the external controller will control the first driving motor 24 to stop working. At this time, the grinding wheel 22 will grind the outer wall of the rotating bearing ring.

[0045] When the grinding work is being performed, the staff operates the external controller, and the external controller will start the third drive motor 42. When the third drive motor 42 is working, it will slowly drive the grinding wheel 22 to rotate, so that the grinding wheel 22 can better grind the outer wall of the rotating bearing ring, and the scraper 19 can also scrape the debris on the surface of the grinding wheel 22. At the same time, through the transmission wheel group 33, it will drive the connecting shaft 48 to rotate slowly, thereby driving the second disc 34 and the third disc 45 rotates slowly, and when the double-beveled semicircular ring column 47 contacts the outer wall of the ball 53, the ball 53 is pushed to move toward the second disc 34. At this time, the through-hole square column 55, the long rod 50, the short rod 56, and the concave-shaped rod 51 are driven to rotate through the second connecting rod 54, and the spring 52 is stretched. At the same time, the gear 44 is driven to rotate and swing toward the second disc 34, and the scraper 19 is rotated and swung toward the supporting mounting frame 20, so that the scraper 19 is separated from the grinding wheel 22. Due to the multiple conical serrations 46 The plurality of conical saw teeth 46 can mesh with the gear 44, so when the gear 44 contacts the plurality of conical saw teeth 46, the plurality of conical saw teeth 46 will drive the gear 44 to rotate 180 degrees, and drive the scraper 19 to rotate 180 degrees through the second connecting rod 54, so that the cleaning strip 32 faces the grinding wheel 22. When the double-beveled semicircular ring column 47 is separated from the outer wall of the ball 53, the spring 52 will contract, and the tension of the spring 52 will drive the long rod 50, the through-hole square column 55, the short rod 56, and the concave round rod 51 to rotate in the opposite direction. The second connecting rod 54, the gear 44 and the scraper 19 rotate in the opposite direction, so that the gear 44 is separated from the plurality of conical saw teeth 46, and the cleaning strip 32 is in contact with the grinding wheel 22. When the cleaning strip 32 is in contact with the grinding wheel 22, the cleaning strip 32 and the surface of the grinding wheel 22 are cleaned. After the scraper 19 has completed the flipping work for many times, the scraper 19 and the cleaning strip 32 can better clean the surface of the grinding wheel 22, so that the grinding wheel 22 can better grind the outer wall of the bearing ring.

[0046] After completing the grinding work, the staff operates the external controller again, and the external controller will control the third drive motor 42 and the second drive motor 29 to stop working. At the same time, the external controller will also control the first servo motor 10 and the second servo motor 13 to work, so that the first ball screw module 11 and the second ball screw module 12 work again, and complete the position adjustment work of the grinding mechanism again, so that the grinding mechanism returns to the initial position. When the grinding mechanism returns to the initial position, the staff operates the external controller again, and the external controller will control the electric cylinder 15 to extend, so that the second support seat 7 returns to the initial position, and the second top column 18 is separated from the bearing ring, which is convenient for the staff to remove the bearing ring after the grinding work is completed.
