Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Referring to Fig. 1, the utility model embodiment include tapered sleeve 1, holding screw 2, hollow shaft 3, pull rod 4, locking nut 5,
Gasket 6, positioning pin 7, elastomer 8, lock sheet 9, bearing 11, snap-gauge 12 and bracket 13.
One end of hollow shaft 3 is driving end, which is equipped with tapered sleeve 1.The other end of hollow shaft 3 is working end, which uses
In installation workpiece 10.Tapered sleeve 1 is the interface of tension mechanism and external drive, and external drive can pass through the forms such as shaft coupling and tapered sleeve
1 connection, drives tapered sleeve 1 to rotate, and then workpiece 10 is driven to rotate.
Lock sheet 9 is mounted on the working end of hollow shaft 3.Lock sheet inclined-plane, the work of hollow shaft 3 are provided on lock sheet 9
Hollow shaft inclined-plane is provided on end, lock sheet inclined-plane is connected with hollow shaft inclined-plane.Lock sheet 9 is locked for squeezing tensioner workpiece 10
Tight piece inclined-plane and the cooperation of hollow shaft inclined-plane, slide lock sheet 9 in hollow shaft 3.Lock sheet 9 can be 2, can also
To be multi-disc.
Pull rod 4 is mounted in hollow shaft 3, and one end is connect with locking nut 5, and the other end is connect with lock sheet 9.Pull rod 4
For tensing simultaneously spreading lock sheet 9, lock sheet 9 is made to squeeze fixed workpiece 10.Locking nut 5 drives pull rod 4 to move to left for rotating,
And then workpiece 10 is locked by lock sheet 9.
Holding screw 2 is connect with hollow shaft 3 and pull rod 4, prevents 4 rotational slippage of pull rod during tensioner.Specifically, pull rod
Waist type groove is provided on 4, holding screw 2 is from the waist type groove that hollow shaft 3 passed through and be caught in pull rod 4.
3 outside of hollow shaft is cylindrical, is sleeved in bearing 11.Bearing 11 is sleeved on bracket 13.Bearing 11 is for rising
The support and rotation of tight mechanism, constrain tension mechanism radial displacement, guarantee the precision of tension mechanism rotation.Bracket 13 is for branch
Support.
Snap-gauge 12 is mounted on bracket 13, and is clamped with hollow shaft 3.Specifically, the middle part of hollow shaft 3 is provided with card slot
14, snap-gauge 12 and card slot 14 are clamped.Snap-gauge 12 guarantees the precision of tension mechanism rotation for constraining tension mechanism axial displacement.
Gasket 6 and nut 5 cooperate, for preventing nut 5 from loosening.
Positioning pin 7 is connect with tapered sleeve 1 and hollow shaft 3, for tapered sleeve 1 and hollow shaft 3 to be fixed together.
Elastomer 8 is mounted on lock sheet 9, for constraining lock sheet 9, so that lock sheet 9 inside contracts, when preventing workpiece from taking out
Lock sheet 9 is fallen.Elastomer 8 can be using forms such as O-ring, rubber bands.Fluted on elastomer 8, elastomer 8 is embedded in groove
And then constrain lock sheet 9.
Locking nut 5 is unclamped, makes pull rod 4 toward moving right, drives lock sheet 9 is past to move right.By 10 cylindrical bore of workpiece
An end cap on lock sheet 9, tighten locking nut 5, make pull rod 4 toward moving left, drive lock sheet 9 toward moving left, lock sheet 9
Outer diameter increases and fixes with 10 Inner extrusion of workpiece.It waits when needed, external drive can drive tapered sleeve 1 to rotate, and tapered sleeve 1 drives sky
