The invention has the technical effects and advantages that:
according to the invention, the planetary roller screw is buffered in the straightening process by utilizing the limiting block and the auxiliary wheel, after the planetary roller screw moves to the upper part of the supporting seat through the first hydraulic cylinder, the third hydraulic cylinder and the second hydraulic cylinder, the planetary roller screw is slowly moved downwards, so that the outer ring of the planetary roller screw is mutually attached to the auxiliary wheel, the distance between the two auxiliary wheels is smaller than the diameter of the planetary roller screw due to the fact that the two auxiliary wheels are stressed to rotate under the action of the arc-shaped pressing block, when the planetary roller screw is mutually attached to the two auxiliary wheels after moving, the planetary roller screw vertically moves downwards through the gravity of the planetary roller screw, therefore, the two auxiliary wheels are stressed to move in the direction away from the planetary roller screw, in this process, the limiting block rotates along the direction of the auxiliary wheel, the rotating block rotates along the direction of the limiting block, the rotating block extrudes the arc-shaped pressing block after the rotating block is stressed, so that the arc-shaped pressing block rotates under the stress, at the moment, the torsion spring compresses, and after the diameter position of the two auxiliary wheels moves from the two auxiliary wheels, the planetary roller screw moves downwards into the arc-shaped groove, the planetary roller screw moves downwards, and resets, the planetary roller screw moves vertically and then moves vertically to the cylindrical roller screw is contacted with the cylindrical power supply, and the two auxiliary roller screw is driven to rotate vertically and the cylindrical power supply, and the planetary roller screw is horizontally moves vertically and moves to the cylindrical power supply, and the cylindrical roller screw is in a protecting case and moves vertically and the auxiliary roller screw is stressed to the cylindrical roller screw, and moves vertically and the cylindrical roller is in a protecting cylinder, and moves and the auxiliary roller. The stopper is followed the direction of auxiliary wheel and is carried out perpendicular downwardly moving, and the stopper compresses the spring, rubber cylindricality briquetting is after resetting, rubber cylindricality briquetting is laminated each other with planetary roller lead screw, rubber cylindricality briquetting presss from both sides the laminating to planetary roller lead screw, and stopper and auxiliary wheel still laminate each other with planetary roller lead screw, at this moment, rubber cylindricality briquetting is perpendicular with planetary roller lead screw with two stoppers, the horizontal direction is spacing, make planetary roller lead screw restriction in the supporting seat, when the straightener extrudees the alignment to planetary roller lead screw, at the in-process of alignment, the horizontal migration can appear in the atress of avoiding planetary roller lead screw, make planetary roller lead screw alignment accurate.
Further, the pole shape cambered surface groove has been seted up to one side that the stopper is close to planetary roller lead screw, and the inside in pole shape cambered surface groove is provided with the internal thread, help the external screw thread in planetary roller lead screw and the internal screw thread in pole shape cambered surface groove to laminate each other, because the internal screw in pole shape cambered surface groove and the external screw thread of planetary roller lead screw mutually support, after the internal screw of stopper and planetary roller lead screw laminate each other, can judge that the straightness accuracy of measuring planetary roller lead screw is in the within range that accords with the requirement, if the internal screw of stopper and planetary roller lead screw can't laminate, can judge that the straightness accuracy of measuring planetary roller lead screw does not accord with the requirement.
Still further, when the alignment is being carried out to the planetary roller lead screw that does not meet the requirements, consider, can produce certain friction between the outer lane department at planetary roller lead screw both ends and the supporting seat, easily cause the damage on planetary roller lead screw surface, and stopper and planetary roller lead screw laminating each other, when planetary roller lead screw is carrying out the extrusion, the both ends atress of planetary roller lead screw carries out the perpendicular upward movement, the tip of planetary roller lead screw is the in-process of removing, planetary roller lead screw extrudees stopper and rubber cylindricality briquetting, and the stopper atress rotates, the rotor rotates along the direction of stopper, the rotor extrudees the arc briquetting in the rotation, and two stoppers have certain clamping force, slow down planetary roller lead screw vertical movement's speed, thereby reduce the external force of planetary roller lead screw and supporting seat, when planetary roller lead screw moves perpendicularly upward, planetary roller lead screw can promote rubber cylindricality briquetting, and rubber cylindricality briquetting is the same for many times atress point, be the below of rubber cylindricality briquetting, probably can cause the damage to rubber cylindricality briquetting, consequently, the fixed mounting helps the wear-resisting service life of rubber cylindricality briquetting in the below the rubber cylindricality briquetting.
Still further, when the planet roller lead screw moves perpendicularly between two stoppers, two stoppers rotate through the rotating block under the promotion of planet roller lead screw, help planet roller lead screw atress to carry out perpendicular upward movement, and when the rotating block atress rotated, because the rotating block is laminated with the arc briquetting each other, the rotating block promotes the arc briquetting and rotates, and the arc briquetting contracts the torsional spring, at this moment, make the arc briquetting have certain thrust to the rotating block under the elasticity of torsional spring, help the stopper still closely laminate with the outside of planet roller lead screw, and under the effect of torsional spring, the planet roller lead screw receives perpendicular upward movement's external force, have certain cushioning effect, slow down initial impact force when carrying out extrusion alignment, make the friction between planet roller lead screw and the supporting seat reduce, avoid the outside of planet roller lead screw to cause certain damage.
In order to reduce the support seat and when the planetary roller screw rod is extruded and straightened, the position where the support seat is contacted with the planetary roller screw rod is worn, so that a round corner is formed at the position where the support seat is contacted with the planetary roller screw rod, the round corner surface is smooth, when the planetary roller screw rod is straightened, friction between the planetary roller screw rod and the support seat is reduced, so that the wear between the planetary roller screw rod and the support seat is reduced, the outer surface of the planetary roller screw rod is ensured not to be damaged, and the planetary roller screw rod is normally used after being straightened.
