[0002] Double-row roller bearings are bearings with two raceways and two rollers. They typically include double-row self-aligning roller bearings and self-aligning roller bearings. Double-row self-aligning roller bearings have two rows of raceways on the inner ring and a spherical raceway on the outer ring. The rollers are drum-shaped. This design allows the bearing to self-align to a certain extent, adapting to angular errors between the shaft and bearing housing or the influence of shaft bending. They are suitable for applications with angular errors caused by installation errors or shaft deflection. During the machining of double-row roller bearings, a chamfering device is needed to chamfer its edges. However, the chamfering device used for double-row roller bearing machining cannot operate quickly, reducing machining efficiency and hindering its practicality. Utility Model Content

The support frame 1 is located on the side away from the second motor 17. Four arc-shaped positioning frames 33 are fixedly installed symmetrically on the side, and positioning rings 32 are slidably installed inside the four arc-shaped positioning frames 33. Four connecting rods 21 are fixedly installed symmetrically on the side of the rotating disk 20 away from the rotating rod 18.

[0025] In use, the interaction of the support frame 1, control switch 2, strip mounting base 3, fixed mounting hole 4, chamfering component 5, and positioning component 6 enables the edge chamfering device for double-row roller bearings to operate quickly, improving processing efficiency and facilitating better practicality. Furthermore, the interaction of the positioning sleeve 14, positioning rod 15, and positioning frame 16 ensures better stability of the movable frame 8 during movement, thereby ensuring the stable operation of the chamfering component 5.

[0026] Working Principle: During operation, the strip-shaped mounting base 3 is first fixed using bolts that match the diameter of the mounting hole 4, thus achieving the fixed installation of the entire device. Then, the double-row roller bearing requiring edge chamfering is placed between the two arc-shaped positioning seats 23. Next, rotating the adjusting block 28 drives the bidirectional screw 27 to rotate, which in turn moves the threaded sleeve 29. The threaded sleeve 29 then moves the positioning slider 30 within the positioning groove 31, ensuring better stability during movement. Simultaneously, the threaded sleeve 29 moves the sliding block 25 within the sliding groove 24, which in turn moves the arc-shaped positioning seats 23. At this point, the two arc-shaped positioning seats 23... The two arc-shaped positioning seats 23 move closer to each other and fix the double-row roller bearing. Then, the horizontal electric telescopic rod 7 is activated to drive the movable frame 8 to move. The movable frame 8 drives the positioning sleeve 14 to slide on the outside of the positioning slide rod 15, which can ensure better stability of the movable frame 8 during movement. At the same time, the movable frame 8 drives the vertical electric telescopic rod 9 to move. The vertical electric telescopic rod 9 drives the chamfering cutter 13 to move laterally through the mounting frame 10 and the drive shaft 12. At the same time, the vertical electric telescopic rod 9 is activated to drive the chamfering cutter 13 to move vertically. When the chamfering cutter 13 moves to contact the edge of the positioned double-row roller bearing, the horizontal electric telescopic rod 7 and the vertical electric telescopic rod 9 are stopped.

[0027] Then, the first motor 11 is started to drive the drive shaft 12 to rotate, which in turn drives the chamfering cutter 13 to rotate. The second motor 17 is then started to drive the rotating rod 18 to rotate, which in turn drives the rotating disk 20 to rotate. The rotating disk 20 drives the positioning ring 32 to rotate within the four arc-shaped positioning frames 33, ensuring better stability during rotation. The rotating disk 20 drives the circular seat 22 to rotate via the connecting rod 21. The double-row roller bearing, positioned and clamped on one side of the circular seat 22, also rotates synchronously. During rotation, the double-row roller bearing undergoes edge chamfering via the rotating chamfering cutter 13. During the chamfering process, control switch 2 controls the horizontal electric telescopic rod 7 and the vertical electric telescopic rod 9 to work, causing the rotating chamfering cutter 13 to generate a certain feed amount to achieve the chamfering operation on the edge of the double-row roller bearing. After the chamfering is completed, the first motor 11 and the second motor 17 are stopped, and then the adjusting block 28 is rotated in the opposite direction to release the fixation of the double-row roller bearing. Then the double-row roller bearing with the chamfered edge can be removed. This allows the edge chamfering device for processing double-row roller bearings to operate quickly during use, improving processing efficiency and thus achieving better practicality.
