VARIABLE-DIAMETER BEARING CLAMP

WIPO Patent Application WO/2021/109602

A1

Disclosed in the present invention is a variable-diameter bearing clamp, comprising a clamping mechanism and a rotary driving mechanism. The clamping mechanism comprises a base, two clamping members oppositely provided on the base, and a clamping driving mechanism. Each clamping member comprises a clamping portion located at an upper end thereof and a clamping arm located at a lower end thereof, the clamping portion comprises an inner ring clamping portion located at an upper part thereof and an outer ring clamping portion located at a lower part thereof, the clamping driving mechanism comprises a driving member and a transmission assembly, the transmission assembly comprises a lead screw, a lead screw nut and two connecting rods, one end of each connecting rod is hinged to the lead screw nut, and the other end thereof is hinged to the clamping arm. The clamp can be adapted to bearings of different sizes for clamping, and strengthened grinding processing on raceways of a bearing inner ring and a bearing outer ring can be performed, thereby improving the working efficiency. Furthermore, the clamp has a simple structure design, effectively reducing manufacturing costs, and has no damage to a bearing surface of a bearing under process during clamping of the bearing.
