For achieving the above object, the technical solution of the utility model is,
The online fast adjuster of a kind of roll change platform, the roll change that is arranged under the roll change platform is adjusted on the dolly; Comprise that positioning seat is arranged at roll change and adjusts on the dolly, radially has the detent that is embedded for the locating piece under the roll change platform on it; Comprise that also a side of detent stretches out and is bent to form a holding section on the described positioning seat, and, have guide groove in the middle of this holding section vertically; In addition, on the positioning seat of this inboard, holding section, also have fixed groove; Governor motion, it comprises, regulates connecting rod, it is installed in roll change and adjusts on the vehicle frame of dolly, and by regulating block and bolting on vehicle frame; The holding section of the described positioning seat of one client link; And the adjusting connecting rod is positioned at regulating block and a side in addition is threaded; Adjusting nut is fixed in the other end of regulating connecting rod; Chuck is sheathed on the adjusting connecting rod, outside the regulating block, and is locked by locking nut.
Again, an end of described adjusting connecting rod is interval with two projections vertically respectively, and the thickness of spacing distance between two projections and described positioning seat holding section is complementary; Wherein, first projection is arranged in the fixed groove of inboard, described positioning seat holding section, regulates connecting rod and passes the middle guide groove in holding section, and second projection is positioned at the outside, positioning seat holding section.
In addition, the guide groove in the middle of the positioning seat described in the utility model holding section is a V-structure, and its bottom is and regulates the arc that connecting rod is complementary.
Described adjusting nut center has a polygon endoporus and the polygon coupling head of regulating interlinking lever end to match, and has screw-threaded counterbore on the end of described adjusting connecting rod screw thread one end, adjusting nut is fixed on the end of regulating connecting rod by pad and screw.The utility model only needs can realize that to regulating the adjusting nut effect of connecting rod outer end positioning seat moves, adjusts by governor motion.
The beneficial effects of the utility model
1, significantly reduces labour intensity: in the process of adjusting,, can utilize the power of hydraulic spanner, significantly reduce labour intensity as torque because adjusting nut is arranged at the end of regulating screw mandrel;
2, online free rapid adjustment: the utility model drives adjusting nut commonly used the way of screw mandrel, change direct adjusting screw mandrel into, nut then is in course of adjustment and keeps static, bigger torque can be provided, the roll change platform is placed on adjust on the dolly and does not have influence on adjustment, realize online rapid adjustment freely;
3, improve the roll change platform and adjust precision: realized online adjustment by application of the present utility model, can accomplish while measuring adjustment, changed and repeatedly adjusted the situation that precision can not guarantee in the past, therefore can make the precision of platform reach best.
