Adopt above technical scheme, during use, gear to be processed is placed on back-up block, then pulls the lower end of pull bar, pull bar band dynamic pressure plate is pressed down, pressing plate down compresses elastic expansion sleeve, elastic expansion sleeve moves down on the conical surface of expansion set cone seat, and because described expansion set cone seat is the thick pyramidal structure in thin lower end, upper end, elastic expansion sleeve is supportted greatly gradually by the conical surface of expansion set cone seat, this elastic expansion sleeve is just gradually by the centre bore swelling of gear to be processed, until gear to be processed is completely fixed.This fixture with very close to each other between the centre bore of machining gears and elastic expansion sleeve, can be good at guaranteeing the centrad of gear when being completely fixed.Simultaneously this fixture, when the gear to be processed of fixedly different size and model, only needs the model of replacing back-up block and elastic expansion sleeve to get final product, and does not need to change whole fixture, provides cost savings.
The bottom outwardly convex of described expansion set cone seat (3) forms annular boss (3a), offer the first shrinkage pool (4a) on the lower surface of elastic expansion sleeve (4), vertically be provided with Compress Spring (7) in this first shrinkage pool (4a), one end of described Compress Spring (7) is connected on the inner bottom surface of the first shrinkage pool (4a), and the other end of this Compress Spring (7) is connected to the upper surface of annular boss (3a).After Gear Processing to be processed, the lower end of releasing lever.The elastic force of described Compress Spring pushes elastic expansion sleeve outward, can automatically elastic expansion sleeve be ejected, and conveniently takes off workpiece, prevents that elastic expansion sleeve and workpiece are stuck.
In order to guarantee that described Compress Spring is not offset in the first shrinkage pool, at the first shrinkage pool, (4 are equipped with elastic cylindrical pin (8) in a), this elastic cylindrical pin (8) is supported in Compress Spring (7), and the lower end of elastic cylindrical pin (8) extend in the upper corresponding through hole of annular boss (3a).
In order to guarantee to a certain extent the centrad of pressing plate, described pull bar (6) top is provided with three protruding blocks (6a), and this protruding block (6a) extend in the upper corresponding spacing shrinkage pool of pressing plate (5).
The lower surface of described pressing plate (5) offers up-small and down-big step through-hole (5b), and the upper end of expansion set cone seat (5) extend in the macropore of this step through-hole (5b), in the aperture of described step through-hole (5b), offers spacing shrinkage pool.When workpiece is compressed by pressing plate, the top of expansion set cone seat is deep in the macropore of step through-hole, continues to compress elastic expansion sleeve, and the top of expansion set cone seat will be connected on the step surface of step through-hole and stop pressing plate to continue to move down, and prevent from pressing quick-fried elastic expansion sleeve.
Beneficial effect: the utility model is used swollen core type clamping mode, axle formula centering effect than before is greatly improved, during processing different model gear, only need the removable parts part also to reduce cost, improved production efficiency, and have that design is ingenious, transformation easily, use the characteristics such as flexible.
