Description

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. Strictly speaking, they are composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. In simple terms, as long as there is an outer ring, inner ring and rolling element, it can be defined as a rolling bearing. During the production process, the inner and outer rings of the bearings need to be polished.

[0027] Through the transmission assembly 5, the rotating rod 7 drives the meshing gear ring 6 to rotate, and the meshing gear ring 6 and the meshing gear plate 8 are meshed and transmitted, so that the meshing gear plate 8 moves as a whole. In the process of the movement of the meshing gear plate 8, the position of the slider 41 is driven to move as a whole, so that the grinding plate 4 assists in clamping the outer ring of the bearing. During the clamping process, the positioning block 713 on the positioning assembly 71 is positioned in the corresponding positioning hole 51, which can ensure that the outer ring of the bearing can be stable and not shake after being fixed.

During the clamping process, the positioning block 713 on the positioning assembly 71 is positioned in the corresponding positioning hole 51.

[0036] When polishing the inner edge of the outer ring, the worm 17 is rotated, and the worm 17 and the worm wheel 18 are matched for transmission, so that the worm wheel 18 rotates, and the worm wheel 18 drives the lead screw 19 to rotate, and the lead screw 19 and the sliding column 121 are threadedly matched, so that the connecting column 13 is extended as a whole, and then the position of the fixed frame 11 is adjusted, so that the polishing column 15 is fitted to the inner edge of the outer ring of the bearing as a whole, and the ejection spring 20 is compressed during the fitting of the polishing column 15, and the low-speed motor 9 and the rotating motor 14 are started at the same time, and the low-speed motor 9 drives the hinged column 12 to rotate as a whole, and drives the polishing assembly 10 to rotate as a whole during the rotation of the hinged column 12. During the rotation of the polishing assembly 10, the polishing column 15 is fitted to the inner edge of the outer ring of the bearing and rotates, and the rotating motor 14 drives the polishing column 15 to rotate, and then the inner edge of the outer ring of the bearing is auxiliary polished, and the overall swing is driven during the low-speed rotation of the low-speed motor 9, so as to perform auxiliary polishing on each position of the inner edge of the outer ring of the bearing.

[0037] After polishing is completed, the push rod 711 is pulled outward, and the push rod 711 drives the positioning block 713 to move, and during the movement of the positioning block 713, the push spring 712 is compressed, so that the positioning block 713 is withdrawn from the positioning hole 51, and the clamped bearing outer ring is disassembled.
