The utility model is realized by the following technical scheme:
a device capable of rapidly dismantling an expansion sleeve of a rocker arm assembly of a vertical mill comprises a screw rod nut, an adjusting screw rod, a claw plate, a fastener and a supporting frame;
the two support frames are symmetrically arranged and fixedly connected through the fixing block in the middle; the upper part of the support frame main body is provided with a plurality of clamping grooves;
the screw rod nut is in threaded connection with the adjusting screw rod;
the adjusting screw rod is in threaded connection with the support fixed block and penetrates through the fixed block;
the claw plate is arranged between the supporting frames in a penetrating way, and is provided with through holes for placing fasteners; the two ends of the fastener are placed in the clamping groove.
Preferably, the clamping grooves are arranged at two ends of the supporting frame, and each end is provided with 3-5 clamping grooves.
Preferably, the through holes are vertically arranged along the main body of the claw plate, and the number of the through holes is 3-5.
The working principle of the utility model is as follows:
when the rocker arm assembly of the vertical mill is disassembled, the supporting frame is placed on the expansion sleeve of the rocker arm assembly, the center point of the expansion sleeve is determined through the adjusting screw rod, then the claw plates are placed at the two ends of the supporting frame, the adjusting screw rod is pressed to adjust the depth of the claw plates, meanwhile, the distance between the claw plates is adjusted, the claw ends of the claw plates hook the expansion bottom sleeve, then the fastening piece is placed in the through hole and placed in the clamping groove, the fastening piece is screwed down, the claw plates are fastened on the supporting frame, and finally the supporting frame is pulled by combining the hydraulic jack, so that the expansion sleeve of the rocker arm assembly of the vertical mill can be disassembled.
The beneficial effects of the utility model are as follows:
1. the device provided by the utility model has the advantages that the structure is simple, the manufacturing is convenient, the expansion sleeve of the rocker arm assembly can be quickly grasped, and the expansion sleeve of the rocker arm assembly can be quickly dismantled by combining an external hydraulic jack to pull the supporting plate, so that the maintenance efficiency of the vertical mill is improved.
