Locking member includes the conical screw hole and through-hole for locking ontology, being arranged in the locking member ontology and being connected, the locking
Ontology is threadedly coupled with the cone, and the locking ontology is connected by drawstring with the air bag.
In one preferred embodiment of the utility model, hollow work-piece localization tool further comprises the cone and tubular
Body by integral forming connects.
In one preferred embodiment of the utility model, hollow work-piece localization tool further comprises that the notch is in strip
Shape.
In one preferred embodiment of the utility model, hollow work-piece localization tool further comprises multiple notch along week
It is arranged to uniform intervals.
In one preferred embodiment of the utility model, hollow work-piece localization tool further comprises that the air bag includes air bag
Ontology, the gas nozzle being arranged on the airbag body, the tracheae being connected with the gas nozzle, the tracheae are connected with air pump.
In one preferred embodiment of the utility model, hollow work-piece localization tool further comprises the airbag body in circle
Tubular.
In one preferred embodiment of the utility model, hollow work-piece localization tool further comprises the outer of the locking ontology
Side wall is provided with coarse structure.
The utility model solves defect present in background technology, and the utility model is simple in structure, easy to use, locking
Ontology is wedge surface cooperation with cone, and when ontology is locked in rotation, the setting of multiple notch is convenient for the contraction of cone, cone
Squeeze resilient sleeve so that resilient sleeve clamps workpiece, and airbag aeration expansion is contacted with the inner wall of hollow work-piece, for resisting hollow work
The inner wall of part avoids the deformation of hollow work-piece, it is ensured that the quality of hollow work-piece.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the preferred embodiment of the utility model；
Fig. 2 is the structural schematic diagram of the jig body of the preferred embodiment of the utility model；
Fig. 3 is the structural schematic diagram of the locking member of the preferred embodiment of the utility model.
Specific implementation mode
The utility model is described in further detail presently in connection with drawings and examples, these attached drawings are simplified
Schematic diagram only illustrates the basic structure of the utility model in a schematic way, therefore it only shows structure related with the utility model
At.
As shown in Figure 1-Figure 3, a kind of hollow work-piece localization tool, including hollow jig body 2, locking member 4 and air bag
6, jig body 2 is fixed on lathe, and the madial wall of jig body 2 is provided with ring-shaped step 8, and bullet is equipped on ring-shaped step 8
Property set 10, jig body 2 includes cone 12 and cylindrical body 14, and cone 12 is circumferentially spaced to be provided with multiple notch 16, lock
The conical screw hole 20 and through-hole 22 that tight part 4 includes locking ontology 18, is arranged in locking member ontology 18 and is connected, can bore
External screw thread is set on shape body 12（It is not shown in figure）, external screw thread matches with conical screw hole 20, locks ontology 18 and cone
12 are threadedly coupled, and locking ontology 18 is connected by drawstring 24 with air bag 6.Hollow work-piece passes through resilient sleeve 10, conical screw hole
20 and through-hole 22, since locking ontology 18 and cone 12 are wedge surface cooperations, when ontology 18 is locked in rotation, multiple notch 16
Contraction convenient for cone 12 is set, and cone 12 squeezes resilient sleeve 10 so that resilient sleeve 10 clamps workpiece, during air bag 6 stretches into
In empty workpiece, 6 inflation of air bag is contacted with the inner wall of hollow work-piece, and the inner wall for resisting hollow work-piece avoids hollow work
The deformation of part, it is ensured that the quality of hollow work-piece.
In order to improve the intensity of jig body 2, the preferred cone 12 of the utility model is integrally formed with cylindrical body 14 to be connected.
The preferred notch 16 of the utility model is in strip so that 12 rapid desufflation of cone improves clamping efficiency.It is multiple to cut
