Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a grabbing tool for bearing assembly. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings need to be assembled during production; bearing assembly is the process of combining the various components of a bearing in a specific process and sequence to form a complete bearing product.

[0003] After the bearings are assembled into finished products, they need to be grabbed and transported. The current finished bearing grabbing device does not have the function of protecting the bearings from falling during grabbing and transportation, which may cause the bearings to fall due to unstable grabbing during transportation. Therefore, it is urgent to design a grabbing tool for bearing assembly. Utility Model Content

The downward movement of the clamping seat 2 will drive the semicircular clamping block 8 to move downward and the connecting rod 7 to move. The movement of the connecting rod 7 will cause the two protective plates 5 to move away, so that the two semicircular clamping blocks 8 can be located inside the inner ring of the bearing, and then the lead screw 13 is driven to rotate by the driving motor 14. The rotation of the lead screw 13 will drive the two slides 12 to move. The movement of the two slides 12 will drive the two protrusions to move. The movement of the two protrusions will drive the two semicircular clamping blocks 8 to move, so that the bearing to be grasped can be limited and fixed, and finally the clamping seat 2 is moved upward. At this time, the two protective plates 5 will move closer as the clamping seat 2 and the bearing move upward, and the grasped bearing can be further protected from falling, thereby improving the safety of the equipment.
