Grabbing chuck for baring ring

Abstract

The invention discloses a grabbing chuck for a bearing ring. The grabbing chuck for the bearing ring further comprises a linkage device; a protective plate composed of a non-magnetic material is arranged in a vertical telescopic groove in a lifted mode; a plurality of movable supporting plates which are uniformly and circumferentially distributed and are composed of non-magnetic materials are elastically and radially movably arranged on the upper end surface of a lower supporting plate; arc-shaped permanent magnets are elastically and radially movably arranged at the outer side end of the movable supporting plates; the lower part of the vertical telescopic groove allows the movable supporting plate and the permanent magnets on the movable supporting plate to radially penetrate through; andthe linkage device comprises an upper linkage device body and a lower linkage device body. According to the grabbing chuck for the bearing ring, through the upper linkage device body, a lifting supporting plate ascends and descends to drive the protective plate to ascend and descend, and the lifting supporting plate and the protective plate are reversely movably arranged; through the lower linkage device body, the lifting supporting plate descends to drive the movable supporting plates to radially move away; and in the descending process of the lifting supporting plate, when the movable supporting plates start to move radially, the protective plate is positioned on the upper sides of the movable supporting plates and the permanent magnets. The grabbing chuck for the bearing ring has the advantages that the permanent magnets can be prevented from accidentally adsorbing metal particles, and the damage to an inner ring body of the bearing ring in the grabbing process is reduced.

Description

Technical field [0001] The invention relates to the technical field of bearing production, in particular to a bearing ring grabbing chuck. Background technique [0002] The bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process, and is an important part of contemporary mechanical equipment. The existing bearing manufacturing production is gradually shifting from manual to fully automated. Robots and manipulators play a vital role in the fully automated production of bearings. The existing manipulator jaws for bearings often use machines with left and right jaw blocks closed. The gripper, although its mechanical gripper has good versatility, it is inconvenient to clamp the circular inner ring or outer ring. The contact point between the gripper and the inner ring or outer ring is only two points. If the clamping force is small, the friction force It is not enough to lift the bearing ring. When the clamping for...
