Description of the drawings
Fig. 1 is the friction measurement device front view of one embodiment of the utility model；
Fig. 2 is the adjustable clamping jaw structure diagram of one embodiment of the utility model；
Fig. 3 is the adjustable clamping jaw right view of one embodiment of the utility model；
Fig. 4 is the adjustable clamping jaw front view of one embodiment of the utility model.
Specific embodiment
The utility model is described in detail below with reference to specific embodiment shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that those of ordinary skill in the art are made according to these embodiments, method or
Transformation functionally is all contained in the scope of protection of the utility model.
Join Fig. 1, friction force checking device 10 includes several clamping jaws 11 positioned at lower part, and clamping jaw 11 can move in the horizontal direction
It is dynamic, and can be around the rotary shaft rotation of friction force checking device 10, with test piece（It is not shown）Moment of friction.It is exemplary
Ground, workpiece are phase regulator.
The free end of clamping jaw 11 is collet 13.Each collet 13 is located on same circumference, and circumferential distance is identical.Frictional force is examined
The rotary shaft of device 10 is surveyed perpendicular to the circumference and passes through the center of circle.Illustratively, clamping jaw 11 is three.
Join Fig. 2 to Fig. 4, collet 13 includes mobilizable detent projection 133 for convexedly stretching in work piece interface 131.The dentation
Protrusion 133 can be meshed with the gear of workpiece surface.
The pedestal of detent projection 133 is embedded inside collet 12.Detent projection is in the direction vertical with work piece interface 131
On can be conditioned and be adapted to workpiece, realize and be in close contact with gear.
Specifically, the first blind hole is set on one surface of collet, the surface is adjacent with work piece interface 131.First blind hole edge
The direction parallel with work piece interface 131 extends and is communicated with the pedestal of detent projection 133.Screw thread is opened up in first blind hole, the
One fastening bolt 135 is configured in the first blind hole, can be abutted against with the pedestal of detent projection 133.
The second blind hole is set on another surface of collet, the surface is adjacent with work piece interface 131.Second blind hole edge and work
The parallel direction of part contact surface 131 extends and is communicated with the pedestal of detent projection 133.Second fastening bolt 137 is configured at second
In blind hole, to apply active force to detent projection 133 along the extending direction of the second blind hole.
First blind hole is vertical with the second blind hole extending direction so that the first fastening bolt 135 and the second fastening screw 137
It wears that direction is vertical, the base portion of detent projection 133 can be fixed from two different directions, after preventing 133 stress of detent projection
It loosens.First blind hole extends with the second blind hole along the direction parallel with work piece interface 131 so that the first fastening bolt 135
The friction that is parallel to detent projection 133 adjusts direction can be provided the base portion of detent projection 133 with the second fastening screw 137
Power.
During adjusting, the first fastening bolt 135, the second fastening bolt 137 are unclamped, detent projection 133 is adjusted and convexedly stretches in workpiece
The distance of contact surface 131, then tighten the first fastening bolt 135, the second fastening bolt 137.
Since workpiece is there are centering error and gearing tolerance, the detent projection 133 of fixed structure cannot fully be engaged with workpiece.
Therefore adjustable structure is set to, it can be neatly in the position for radially adjusting detent projection 133 of rotational trajectory.
During test, workpiece is put into positioning fixture, and positioning fixture is driven to rise to test station.Collet 11 moves in the horizontal direction
It is dynamic, gather with clamping workpiece, the detent projection 133 of collet 13 is meshed with the gear parts on workpiece.If gear and dentation
Protrusion 133 cannot be fitted close, and be adjusted as previously described.Then collet rotates, and band moving gear rotates, testing friction torque.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
For bright book as an entirety, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can
With the other embodiment of understanding.
The a series of tool that the feasibility embodiment only for the utility model is described in detail of those listed above
Body illustrates, they are all to be made without departing from the utility model skill spirit not to limit the scope of protection of the utility model
