Protective pad 11, the material of described neonychium 11 and shape are according to being tightened the intensity of workpiece 12, hardness, surface appearance and tightening strength
Depending on size；The inwall both sides of described first jaw 2 and described second jaw 3 are additionally provided with for fixing described neonychium 11
Draw-in groove.
As shown in figure 12, the tightening method of the totally-enclosed anti-surface damage device for screwing up described in technique scheme four is:
Step one, as shown in figure (H), along workpiece 12 circumference to the second jaw 3 side rotary handle counterclockwise 4, the first jaw 2
Unclamp with the second jaw 3 but there is no opening, now, make handle 4, first jaw 2 of this device and the second jaw 3 be still within closing
And connection status；
Step 2, as shown in figure (I), pushes and is enclosed within workpiece 12 outer surface by this device from workpiece 12 outer end；
Step 3, as shown in figure (J), turns clockwise handle 4 to certain position along workpiece 12 circumference to the first jaw 2 side
Locking workpiece 12；
Step 4, as shown in figure (K), continues rotary handle 4 along workpiece 12 axis circumference and drives workpiece 12 to rotate to properly
Position；
Step 5, as shown in figure (L), along workpiece 12 circumference to the second jaw 3 side rotary handle counterclockwise 4, unclamps workpiece
12 and make this device return to initial position；
Step 6, circulation step three to step 5, i.e. repeats to be rotated both clockwise and counterclockwise handle 4, until workpiece 12 reaches
To requiring position and tightening；
Step 7, as shown in figure (M), extracts this device to workpiece 12 outer end, and workpiece 12 separates with this device, completes work
Part 12 is tightened.
The principle of the totally-enclosed anti-surface damage device for screwing up shown in four technical schemes of the present invention is:
1, described first jaw the 2, second jaw 3 and handle 4 are to connect into one by the round pin of three matched in clearance to close
The device for screwing up closed, all two components being connected by round pin be all a side member be both shoulders and opposite side component for middle single
The structure of shoulder, is matched in clearance between round pin and component hole, and side pieces all can rotate around round pin or slide, two jaws simultaneously
Neonychium 11 is fixed by draw-in groove in inner side, neonychium 11 contact workpiece 12, and neonychium 11 had both played transmission torsion, rotated circle
The effect of workpiece 12, plays again the effect preventing workpiece 12 surface damage.It is a pair symmetrical circular arc inside cause two jaws
Inwall, circular arc inwall radius is configured according to the thickness after workpiece 12 radius and neonychium 11 compression, increases neonychium 11
Contact area and frictional force with workpiece 12.
2, the operation of this device for screwing up is used:
Tighten workpiece 12: turn clockwise to the direction of the first jaw 2 side handle 4 time, handle 4 fixes round pin 5 around first
(or folding round pin 1) rotates, and drives the slip round pin 6 elongated hole inwall on the second jaw 3 roll from inside to outside or slide, gradually
Tighten up the first jaw 2 and the second jaw 3, by neonychium 11 workpiece pressing 12；The anglec of rotation and the revolving force of handle 4 are the biggest,
It is the nearest that two jaws are received, and the power of workpiece pressing 12 is the biggest, and the frictional force being passed to workpiece 12 by neonychium 11 is the biggest, rotates work
The strength of part 12 is the biggest.
Unclamping workpiece 12 and return device for screwing up: when the direction rotary handle 4 counterclockwise of the second jaw 3 side, handle 4 is around
One fixes round pin 5 (or folding round pin 1) rotates, and drives the slip round pin 6 elongated hole outer wall ecto-entad on the second jaw 3 to roll
Or slide, the first jaw 2 and the second jaw 3 unclamp workpiece 12；Continuing to rotate, first fixes round pin 5 (or folding round pin 1) promotes
Second jaw 3 and whole device for screwing up return initial position,
Workpiece 12 is tightened in circulation: the direction to the first jaw 2 side turns clockwise handle 4 the most again, it is achieved workpiece pressing
12, rotational workpieces 12, unclamp workpiece 12, device for screwing up return initial position circulation operation, until tightening workpiece 12.
Because the direction of rotation of handle 4 is identical when workpiece pressing 12 tightens workpiece 12 with rotation, unclamps workpiece 12 and return
During initial position, the direction of rotation of handle 4 is identical, thus whole tighten workpiece 12 during can rotate continuously with both forward and reverse directions,
It is rapidly completed and tightens operation.
3, when the direction rotary handle 4 of the first jaw 2 side, the first jaw 2 and the second jaw 3 and the connection side of handle 4
Respectively one being drawn contrary power by a top, because of the first jaw 2 and the second jaw 3 opposite side, by folding round pin 1, (or second fix round pin
13) connecting, so the strength major part of two jaws self rotational workpieces 12 cancels each other, residue small part is by neonychium 11
Frictional force is offset, and turn handle 4 strength is the biggest, and thrust is the biggest, so after turn handle 4 makes two jaw workpiece pressings 12,
Will not sliding between two jaws and workpiece 12.
