Mechanism used for clamping bearing ring

Abstract

The invention discloses a mechanism for clamping a bearing ring, which comprises a sleeve, the inner wall of the sleeve abuts against a plurality of arc-shaped clamping plates, and the clamping plates face the side wall of the inner wall of the sleeve A first limiting groove and a second limiting groove are formed on the top, and the first limiting groove and the second limiting groove are both arc-shaped and the depth of the second limiting groove is greater than the depth of the first limiting groove. The first limit groove and the second limit groove are connected by an arc-shaped transition groove. An annular installation groove is formed in the sleeve, and a rotating ring is inserted in the annular installation groove. A corresponding limit ball, the limit ball is against the inner wall of the annular installation groove on one side of the clamping plate, and the outer wall of the rotating ring between the two limit balls is provided with an arc-shaped rack. The arc-shaped rack is meshed with a driving gear, and a compression spring is connected between the limit ball and the rotating ring. The invention can clamp the outer wall of the bearing ring with a small force so as not to damage the bearing.

Description

Technical field: [0001] The invention relates to the technical field of robots for bearing production, in particular to a mechanism for clamping bearing rings. Background technique: [0002] Bearing is a component that fixes and reduces the load friction coefficient in the process of mechanical transmission, and is a widely used component in contemporary mechanical equipment. The existing bearing manufacturing production is gradually changing from manual to fully automated, and robots and manipulators play a vital role in the fully automated production of bearings. Existing manipulator grippers for bearings often use mechanical grippers with closed left and right claw blocks. Although this kind of mechanical grippers has good versatility, it is inconvenient to clamp the inner ring or outer ring of the ring-shaped bearing. There are only two points of contact with the inner ring or outer ring. When the clamping force is small, the friction force is not enough to lift the bea...
