It is the key index that flywheel machining precision is considered that flywheel transient equilibrium detects.For ensureing that flywheel transient equilibrium detects the machining precision of duplicate removal operation, for the flywheel product that dynamic balance accuracy higher grade, existing transient equilibrium detects the ringfeder clamping structure that fixture adopts the internal-hole type that rises, and it requires on flywheel with endoporus.Certainly, for the dish like members of common band inner hole structure, when doing transient equilibrium and detecting, this internal-hole type transient equilibrium of rising also can be adopted to detect fixture.
But, for without the dish like members of endoporus with boss or little major axis structure, when doing transient equilibrium and detecting, the ringfeder clamping structure of the conventional internal-hole type that rises cannot be adopted, bring inconvenience to detection.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of inner position to bore expansion sleeve type dynamic balance jig, to solve without the dish like members of endoporus with boss or little major axis structure, when doing transient equilibrium and detecting, the ringfeder clamping structure of the conventional internal-hole type that rises cannot be adopted, to detecting the technical matters of making troubles.
For solving the problems of the technologies described above, the technical solution of the utility model is: expansion sleeve type dynamic balance jig, comprise positioning seat, described positioning seat comprises installation portion and has the location division of plane of orientation, described positioning seat is provided with the through hole extending to described installation portion from described plane of orientation along its axis direction, chuck is slidably fitted with in described through hole, described chuck comprises connecting portion and hollow clamping section, described connecting portion connects a force application apparatus, described hollow clamping section is tapered, and the small end of described hollow clamping section is arranged near described connecting portion, large end is arranged near described plane of orientation, described hollow clamping section is evenly equipped with some openings, described opening extends along the generatrix direction of described hollow clamping section.
Improve as one, described opening has three, and the angle between adjacent two described openings is 120 °.
Improve as one, described force application apparatus comprises pull bar, and one end of described pull bar is spirally connected described connecting portion, and the other end connects a cylinder.
Improve as one, described installation portion is disk-shaped, and described installation portion shows some mounting holes along its axis direction circular array.
As further improvement, described mounting hole has four, and each described mounting hole is counter sink.
Improve as one, described installation portion and location division are set to one; Described connecting portion and hollow clamping section are set to one.
After have employed technique scheme, the beneficial effects of the utility model are: because expansion sleeve type dynamic balance jig comprises positioning seat, described positioning seat comprises installation portion and has the location division of plane of orientation, described positioning seat is provided with through hole along its axis direction, chuck is slidably fitted with in described through hole, described chuck comprises connecting portion and hollow clamping section, described connecting portion connects a force application apparatus, described hollow clamping section is evenly equipped with some openings, thus in use, dish like members is placed on the plane of orientation of positioning seat, and make the boss of dish like members or little major axis be positioned at the hollow clamping section of chuck, by force application apparatus, chuck is slided to the direction away from plane of orientation along through hole, hollow clamping section can produce drawdown deformation and hold the boss of dish like members or little major axis tightly, and eliminate the gap error at dish like members clamping position, Self-centering Action can also be played simultaneously, guarantee transient equilibrium accuracy of detection and reliability, final realization detects with the dish like members transient equilibrium of boss or little major axis structure the object that duplicate removal operation clamps without endoporus.
The expansion sleeve type dynamic balance clamping lamps structure that the utility model provides is simple, easy to operate, reduces transient equilibrium operation non-cutting time, improves production efficiency, and eliminate the gap error at dish like members clamping position, guarantee transient equilibrium accuracy of detection and reliability.
Because described force application apparatus comprises pull bar, one end of described pull bar is spirally connected described connecting portion, and the other end connects a cylinder, is exerted a force to chuck by cylinder and pull bar, makes force application apparatus structure simple and cost is low.
