Abstract
The invention relates to a composite taper sleeve device for providing prestress. The composite taper sleeve device comprises a main taper sleeve and auxiliary tapers. The inner surface of the main taper sleeve is matched with the outer surface of a workpiece to be pre-tightened. When the outer surface of the workpiece to be pre-tightened is a cylindrical face, the inner surface of one end of the main taper sleeve is in interference fit with the outer surface of the workpiece to be pre-tightened. When the outer surface of the workpiece to be pre-tightened is a taper face, the inner surface of the small end of the main taper sleeve is in interference fit with the outer surface of the workpiece to be pre-tightened. Three or more auxiliary tapers are arranged in counter bores in the section of the large end of the main taper sleeve and are in interference fit with the counter bores. Only one main taper sleeve and three or more auxiliary tapers need to be manufactured, and when large prestress is needed by the partial area of the workpiece, a composite taper sleeve can be arranged in the partial area and used for obtaining prestress exceeding prestress provided by a single taper sleeve; and when the workpiece is long and large or complex, the main taper sleeve can be manufactured into a plurality of units according to the appearance size of the workpiece, and therefore prestress can be obtained in all areas of the workpiece.
Description
Technical field
The present invention relates to a kind of for providing prestressed Composite Cone covering device.
Technical background
Pretightening force is before being subject to work loads, in order to strengthen reliability and the tightness of connection, to prevent from being subject to occurring between load rear connectors gap or Relative sliding and the power added in advance.Very generally heat shrunk method of applying in current engineering field reaches pretensioning effect, when workpiece is comparatively large or workpiece is more complicated, heat shrunk method technique implements difficulty larger.
Summary of the invention
A kind of technique is the object of the present invention is to provide simply to implement easily for providing prestressed Composite Cone covering device.
To achieve these goals, technological scheme of the present invention is, one is used for providing prestressed Composite Cone covering device, it comprises female coupling tap cover and son cone, the internal surface of described female coupling tap cover with treat that the outer surface of preload piece matches, when when the outer surface of preload piece is cylndrical surface, the internal surface that described female coupling tap overlaps end, one end with treat that the outer surface of workpiece of pretension is that interference is mated, when when the outer surface of preload piece is the conical surface, the small end internal surface of described female coupling tap cover with treat that the outer surface of workpiece of pretension is that interference is mated, the large end section radial direction of described female coupling tap cover is evenly provided with the counterbore of more than three or three, described son cone to be arranged in counterbore and to be interference fit with counterbore.
Preferably, described counterbore is the taper hole outwards expanded, and tapering and the counterbore tapering of described son cone match.
Preferably, the outer surface of described female coupling tap cover is the conical surface, and the counterbore of described female coupling tap cover is arranged on the large end of female coupling tap cover.
Advantageous Effects of the present invention is, the present invention only needs the son cone of making female coupling tap cover and more than three or three, particularly when workpiece regional area needs more high-prestressed, compound tapered sleeve can be arranged on this place, in order to obtain the prestressing force exceeding single tapered sleeve and provide, and when workpiece is comparatively grown up or be more complicated, according to workpiece configurations size, female coupling tap cover can be made multiple unit, thus all can obtain prestressing force at workpiece regional, and install very convenient, whole device is simple, easy to implement.
