A kind of steel ball quick-locking device
Technical field
This utility model relates to a kind of locking device, particularly relates to a kind of steel ball quick-locking device.
Background technology
At present, locking method conventional in machining is adopted and is tightened by bolts, and the mode of this bolt locking is more common,
But bolt from front workpiece pressing, and can only be wasted time and energy, thus limit execution conditions and the environment of locking, than
As, sometimes need the most quickly to strain, if at this time or being difficult to reach requirement with bolt.
Summary of the invention
Technical problem to be solved in the utility model is that needs offer one can fast lock in mechanical processing process
Tight device, further, additionally it is possible to realize the requirement of reverse side quick locking.
To this, this utility model provides a kind of steel ball quick-locking device, including: fixed mount, support shaft, cover plate, steel ball,
Pull bar and rotating disk, described fixed mount, support shaft, cover plate and rotating disk are provided with through hole, and described pull bar is depended on by described through hole
In secondary insertion cover plate, support shaft, rotating disk and fixed mount, described steel ball is arranged between described fixed mount and rotating disk.
Further improvement of the utility model is, described fixed mount is arranged in described rotating disk.
Further improvement of the utility model is, described rotating disk is arranged in described support shaft.
Further improvement of the utility model is, the side of described support shaft is provided with open slot, outside described rotating disk
Jack it is provided with on circle.
Further improvement of the utility model is, described fixed mount is provided with pilot hole.
Further improvement of the utility model is, the inner ring of described rotating disk is provided with cam member.
Further improvement of the utility model is, also includes that base plate, described base plate are provided with the lower section of described fixed mount.
Further improvement of the utility model is, also include centring ring, described centring ring be arranged at described support shaft and
Between cover plate.
Further improvement of the utility model is, also includes connector, and described cover plate is by connector and described support
Axle is fixing to be connected.
Further improvement of the utility model is, described connector is soket head cap screw.
Compared with prior art, the beneficial effects of the utility model are: by draw lever locking on workpiece, only need to be by pull bar
It is sequentially inserted in cover plate, support shaft, rotating disk and fixed mount by described through hole, acts on steel ball by rotating described rotating disk
Power is delivered on the inclined-plane of pull bar, it becomes possible to quickly strain workpiece;It is real from the negative that this utility model can quickly realize workpiece
Now strain, it is to avoid when front compresses, nut or pressing plate are on the impact of Tool route in the course of processing, and when saving clamping
Between, time saving and energy saving, it is possible to be effectively improved production efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings, preferably embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, this example provides a kind of steel ball 4 quick-locking device, including: fixed mount 1, support shaft 2, lid
Plate 3, steel ball 4, pull bar 5 and rotating disk 7, described fixed mount 1, support shaft 2, cover plate 3 and rotating disk 7 are provided with through hole, described in draw
Bar 5 is sequentially inserted in cover plate 3, support shaft 2, rotating disk 7 and fixed mount 1 by described through hole, and described steel ball 4 is arranged at described fixing
Between frame 1 and rotating disk 7.
As it is shown in figure 1, fixed mount 1 described in this example is arranged in described rotating disk 7, described rotating disk 7 is arranged at described support shaft 2
In, the side of described support shaft 2 is provided with open slot 10, the outer ring of described rotating disk 7 is provided with jack, on described fixed mount 1
It is provided with pilot hole, the inner ring of described rotating disk 7 is provided with cam member;This example further preferably includes base plate 6, centring ring 8 and connects
Fitting 9, described base plate 6 is provided with the lower section of described fixed mount 1, described centring ring 8 be arranged at described support shaft 2 and cover plate 3 it
Between, described cover plate 3, support shaft 2 and base plate 6 connect by connector 9 is fixing, and described connector 9 is preferably soket head cap screw.
Pull bar 5 screw is locked at by this example by the through hole in the middle of described fixed mount 1, support shaft 2, cover plate 3 and rotating disk 7
Together, being then inserted in cover plate 3 by pull bar 5 as shown in Fig. 1 and Fig. 2, workpiece and the upper surface of cover plate 3, workpiece is put well
After, only need to be inserted in the jack of described rotating disk 7 through the open slot 10 of described support shaft 2 with instruments such as spanners, rotating spanner
Driving described rotating disk 7 to rotate Deng instrument, described rotating disk 7 makes steel ball 4 by described fixed mount 1 by its internal cam member
The inclined-plane of described pull bar 5 pushed down by pilot hole, by the pressure obliquely on inclined-plane thus strain workpiece.
Pull bar 5 is locked on workpiece by this example, only need to by pull bar 5 by described through hole be sequentially inserted into cover plate 3, support shaft 2,
In rotating disk 7 and fixed mount 1, act on the power on steel ball 4 by the described rotating disk 7 of rotation and be delivered on the inclined-plane of pull bar 5, it becomes possible to
Quickly strain workpiece;This example can quickly realize workpiece and realize tension from the negative, it is to avoid nut or pressing plate when front compresses
On the impact of Tool route in the course of processing, and save the clamping time, time saving and energy saving, it is possible to be effectively improved production efficiency.
The detailed description of the invention of the above is better embodiment of the present utility model, not limits this practicality with this new
The scope that is embodied as of type, scope of the present utility model includes being not limited to this detailed description of the invention, all according to this utility model
Shape, structure made equivalence change all in protection domain of the present utility model.
