Description
Technical field
The utility model relates to wind wheel technical field, especially a kind of slide block type inner hole for wind wheel dynamic balancing measurement is swollen
Clamper.
Background technique
Wind wheel will test dynamic balancing, and wind wheel is needed to be mounted on test machine, be specifically first fixed on key screw workpiece
It is artificial before testing to need that screw is installed on workpiece on fixture, and by the groove in screw line-up jig shaft, screw is tightened,
To prevent the displacement dislocation of workpiece opposed jaw.And in practice, it has been found that inner hole of workpiece and clamp shaft are easy to exist after installation screw
Bias directly affects test accuracy.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model is provided in a kind of slide block type for wind wheel dynamic balancing measurement
Hole swelling fixture.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of slide block type inner hole swelling fixture for wind wheel dynamic balancing measurement, including the clamp shaft in main body and main body,
The clamp shaft is hollow shaft, and push rod, the tapered sliding block of grafting on front side of the push rod, wherein described are fitted in the clamp shaft
The conical surface being provided among oblique front side between taper inner side of slider and push rod, the push rod rear side are connected with thrust cylinder.
As a preference, it is provided with side through hole on front side of the clamp shaft, the taper sliding block is arranged on side through hole both ends,
The taper slide block set is equipped with reseting ring.
As a preference, guide bracket is provided on rear side of the main body.
As a preference, the putting back-end is provided with round fixture block, and the thrust cylinder passes through fastener and push rod
Connection, wherein being provided with convex shape slot on the fastener blocks round fixture block.
The beneficial effects of the utility model are: the fixture realizes fixture swelling and release using clamp shaft cooperation taper sliding block
Workpiece removes the trouble for installing and uninstalling screw from, and crossing Cheng Qian in swelling due to inner hole of workpiece and clamp shaft is interference fit,
There are enough spaces to avoid eccentricity issues, test result is more accurate.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The utility model is further elaborated.For the thorough explanation present invention, some spies can be related in following description
Determine details.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields uses this
These of place describe and state that the others skilled in the art into fields can more effectively introduce their work essence.
Referring to Fig.1, Fig. 2, a kind of slide block type inner hole swelling fixture for wind wheel dynamic balancing measurement, including main body 1 and master
Clamp shaft 2 on body 1, the clamp shaft 2 are hollow shaft, are fitted with push rod 3, the 3 front side grafting of push rod in the clamp shaft 2
Tapered sliding block 4, wherein being provided with the conical surface among oblique front side, the push rod between 4 inside of the taper sliding block and push rod 3
3 rear sides are connected with thrust cylinder 5.When specific works, workpiece 9 is manually put into clamp shaft 2, the external force pulling of thrust cylinder 5 pushes away
Bar 3 simultaneously drives taper sliding block 4 to being pushed forward, and clamp shaft 2 is forced to move to outside circumference, thus swelling inner hole of workpiece.In conical degree of conical surface
In lesser situation, taper sliding block 4 is enough self-locking, and workpiece 9 would not unclamp automatically.In the present embodiment, 2 front side of clamp shaft
It is provided with side through hole 21, the taper sliding block 4 is arranged on 21 both ends of side through hole, and the taper sliding block 4 is set with reseting ring 41, when pushing away
Strength cylinder 5 pulls back push rod 3, and taper sliding block 4 is just resetted by the effect of reseting ring 41 of elasticity is lower, to unclamp workpiece 9.
It is provided with guide bracket 6 on rear side of the main body 1, for assisting guidance push rod 3 to be pushed forward process.
3 rear end of push rod is provided with round fixture block 7, and the thrust cylinder 5 is connect by fastener 8 with push rod 3, wherein institute
It states and is provided with convex shape slot 81 on fastener 8 and blocks round fixture block 7, guarantee firm enough when thrust cylinder 5 holds push rod 3 and do not influence
Push rod 3 follows 2 rotation of clamp shaft or rotates by a small margin.
According to above-mentioned principle, the utility model can also be made appropriate changes and modifications to the above embodiments.Therefore,
The utility model is not limited to specific embodiment disclosed and described above, to some modifications and changes of the utility model
It should also be as falling into the protection scope of the claims of the present utility model.
By it was verified that this fixture is easy to use, being suitable for axial aperture structure is cylindric and with metal axle sleeve
Wind wheel test wind wheel computing ballance correction.
