Described connection tooth arranges multiple, arranges slot between two adjacent connection teeth, by connecting tooth, being connected, alleviating extruding force by slot with miscellaneous part, avoids expansion set to be squeezed the excessive damage of power.
Described expansion set circle centre position also arranges the through hole through expansion set self, and described through hole is corresponding with fixed cover through hole to be become axially to be communicated with, and makes fixture when the workpiece of the revolving bodies such as clamping cylinder cap, ensures axiality.
Described expansion set packing ring is integral type precision casting, comprises connecting pin and fixture, and described connecting pin is arranged on the outside of fixture, is fixedly connected with fixture by connecting pin with expansion set.
Described connecting pin arranges pin hole, and described pin hole is corresponding with the connecting screw hole of expansion set, is fixedly connected with after being screwed with expansion set.
Described fixture arranges the connecting through hole through self, and described connecting through hole becomes axial and is communicated with the through hole of fixed cover and the through hole of expansion set, make fixture when the workpiece of the revolving bodies such as clamping cylinder cap, ensure axiality.
Described backer is integral type precision casting, also comprises fixture and handgrip, and described handgrip is arranged on the side of fixture, is fixedly connected with expansion set packing ring by fixture, by handgrip grabbing workpiece.
Described fixture arranges the through hole through self, the multiple connection screw socket of arranged outside of through hole, the through hole of the connecting through hole of described through hole and fixture, the through hole of expansion set packing ring, the through hole of expansion set and fixed cover becomes and is axially communicated with, make fixture when the workpiece of the revolving bodies such as clamping cylinder cap, ensure axiality.
Described handgrip arranges multiple, and handgrip also arranges limited block, is increased the contact surface of grabbing workpiece by limited block, and the workpiece fixedly grabbed, avoid workpiece loose or dislocation, workpiece is not yielding because increasing contact surface, not easily occurs impression.
Described fixture is when reality uses, first fixed cover is screwed on lathe, then expansion set packing ring is screwed in expansion set, load together with expansion set in fixed cover, pull bar on lathe is passed through screw tightening through expansion set packing ring, finally backer is loaded expansion set internal fixtion on fixed cover.During grabbing workpiece, workpiece is put into expansion set, captured and fixation workpiece by the handgrip of backer, workpiece is fixed in expansion set by pull bar tension.
The beneficial effects of the utility model are: provide a kind of expansion sleeve type fixture for Vehicle Processing rational in infrastructure, this fixture, when the workpiece of the revolving bodies such as clamping cylinder cap, can not only ensure axiality, can also be not yielding because increasing contact surface, not easily occur impression.
