In order to solve the technical problem, the utility model adopts the following technical scheme:
a roller box adjusting assembly in a high-speed wire high-speed area comprises a steel adjusting nut, wherein two symmetrical side ends of the steel adjusting nut are provided with trunnions, a steel cuboid sliding block is sleeved on the trunnions, a double-thread copper bush is arranged in the steel adjusting nut, and the size of the inner thread of the double-thread copper bush is the same as that of the original copper adjusting nut; and two limiting blocks are respectively arranged on two sides of the junction point of the steel adjusting nut and the double-sided threaded copper bush to ensure that the double-sided threaded copper bush is not easy to withdraw from the steel adjusting nut when an external screw drives the adjusting nut to move, or at least one threaded through hole is arranged on the peripheral wall of the steel adjusting nut, a jackscrew in threaded fit is arranged in the threaded through hole, the length of the jackscrew is smaller than that of the threaded hole, and a straight or cross groove is arranged at the outer end of the jackscrew.
Further, the steel adjusting nut is made of 45# steel.
Furthermore, the steel cuboid sliding block is made of 45# steel.
Further, the trunnion thickness is 18 mm.
Furthermore, the original position of the center of the steel adjusting nut is turned with an inner buckle which is 7mm larger than the inner buckle of the original copper adjusting nut.
Furthermore, the limiting block is a limiting screw.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the utility model discloses an use and improved the availability factor of adjusting nut and slider assembly greatly, reduced workman's change intensity, when improving production efficiency, reduced the spare parts consumption of this assembly.
The utility model discloses according to this adjustment assembly each position atress characteristics, change its intensity of resisting the external force in proper order, nevertheless do not lose the characteristic of original copper matter, fundamentally has solved the problem that actual production faces, and cylindrical slider changes the cuboid into in addition for this adjustment assembly's stability has obtained the leap of matter, and the effect performance is obvious.
