Abstract
The invention provides a steel-ball type inner-expansion self-centering structure capable of realizing rapid location and ensuring no deformation of blank holes, reliability in location and stability in product quality. The steel-ball type inner-expansion self-centering structure comprises a flange plate and vertical plates on two sides, wherein the vertical plates on two sides are arranged on two sides of the flange plate; a locating block is fastened on the vertical plate on one side, and a clamping block is fastened on the vertical plate on the other side; a chuck is fastened on the clamping block; and the chuck and the locating block are arranged oppositely. The steel-ball type inner-expansion self-centering structure is characterized in that a locating plate is arranged below the flange plate; a locating hole is arranged in the locating plate; a supporting part of an expansion sleeve is sleeved in the locating hole; the center of the supporting part of the expansion sleeve is provided with a central hole; a circular-ring groove is arranged in the inner circular surface of the expansion sleeve; steel balls are uniformly distributed in the circular-ring groove; an expansion pin is concretely a taper pin which is constrictive downwards; the tapered surface of the taper pin is clung to the steel balls; and the supporting end of the taper pin is fastened by a locking nut and connected to the lower end surface of the supporting part of the expansion sleeve after passing through the central hole.
Description
Technical field
The present invention relates to the location structure technical field of workpiece, be specially a kind of steel-ball type internal expanding self contering structure.
Background technology
Existing alignment pin locate mode, not only mounting operation speed is slow, and due to the distortion of blank hole, alignment pin can not coordinate completely with blank hole, causes and locates unreliable and unstable product quality.
Summary of the invention
For the problems referred to above, the invention provides a kind of steel-ball type internal expanding self contering structure, it makes location fast, guarantees that blank hole is indeformable, makes to locate reliable and constant product quality.
A kind of steel-ball type internal expanding self contering structure, its technical scheme is such: it comprises ring flange, vertical plates on both sides, the described riser of both sides is positioned at the both sides of described ring flange, wherein described in side, riser is fastened with locating piece, riser described in opposite side is fastened with clamp, described clamp is fastened with described chuck, described chuck, locating piece is arranged in opposite directions, it is characterized in that: the below of described ring flange is provided with location-plate, described location-plate has locating hole, the support of expansion set is set in described locating hole, the center of the support of described expansion set has centre bore, the inner headed face of described expansion set has annular groove, steel ball is evenly equipped with in described annular groove, expansion pin is specially the taper bolt of retracted downward, the taper seat of described taper bolt is fitted described steel ball, after the supported end of described taper bolt runs through described centre bore, locking nut is fastenedly connected the lower surface of the support in described expansion set.
After adopting the present invention, one end of part is fixed by chuck, locating piece, band blank hole one end of part is set in expansion set, along with taper bolt is drop-down gradually, make steel ball gradually to external diffusion, and then expansion set is fitted the inner side of blank hole completely, it makes location fast, guarantee that blank hole is indeformable, make to locate reliable and constant product quality.
