Description

Wind-powered electricity generation gear box bearing outer race stop slot processing clamping frock Technical Field The utility model relates to the field of maintenance of wind power gearboxes, in particular to a clamping tool for machining a stop groove of a bearing outer ring of a wind power gearbox. Background Wind power generation has been rapidly developed in recent years due to the advantages of no pollution, low construction cost, and the like. The problem of outer race frequently occurs in the high-speed bearing of the wind power gear box, the stop groove is added to the outer race of the bearing, and the scheme of installing the stop pin can perfectly solve the problem. If the original bearing is replaced by a bearing with a stop groove, the cost is increased, and the normal operation of the delay fan cannot be met in a possible goods period. Disclosure of utility model The utility model provides a clamping tool for machining a stop groove on an outer ring of a bearing of a wind power gear box, which aims to solve the defects in the prior art, and is strong in universality, low in cost, capable of rapidly reacting and saving time. The technical scheme adopted for solving the technical problems is as follows: wind-powered electricity generation gear box bearing outer lane stop slot processing clamping frock, its characterized in that: The V-shaped block is fixedly arranged on the workbench; The lower part of the V-shaped block is provided with a groove; the cylindrical rod is transversely placed in the groove, and a screw hole is formed on the outer circle of the cylindrical rod; The bearing outer ring is placed in a V-shaped groove of the V-shaped block, and one end face of the bearing outer ring is placed on the side wall of the V-shaped groove with the through hole; pressing the other end face of the bearing outer ring by the strip-shaped pressing plate, the strip-shaped pressing plate is provided with a through hole; The screw rod passes through the through-hole of bar clamp plate, the through-hole of intercommunication V type groove and recess on bearing outer lane, the V type piece, and the screw of cylinder pole is gone into to the lower extreme spiro union of screw rod, and the nut spiro union is established in the upper end of screw rod and is compressed tightly the upper surface of bar clamp plate, and the cylinder pole is supported at the lateral wall of recess, and bar clamp plate presses the bearing outer lane on the lateral wall that has the through-hole of V type groove.
