Between connected by connecting rod 7, ball-screw 9 is respectively fixed in the L-type support of both sides, 9 one end of ball-screw is fixed on L-type
The top of stent vertical edge, the other end are fixed on the base of L-type support；
The upper end of ball-screw 9 is fixed with rotatable rocking bar 1, and the nut 6 coordinated with it is arranged on ball-screw 9,
Nut 6 is connected with fixed block 5, and supporting rod 10 is connected between the fixed block 5 of both sides, and vari ramp 11 is placed on supporting rod 10,
The bottom of vari ramp 11 is fixed between the L-type support of both sides, is fixed on the outside of the L-type support of both sides at corresponding ball-screw 9
There is dial scale 4.
Further, 9 upper end of ball-screw is arranged with rocking arm sleeve 2, and rocking bar 1 is fixed on rocking arm sleeve 2, ball
9 lower end of leading screw is fixed on by pedestal sliding block 8 on the base of L-type support.
Further, the ball-screw 9 and the base angle at 45 ° of L-type support, the long side of L-type support is as base.
Further, between the bottom of the vari ramp 11 is fixed on the L-type support of both sides by axis, vari ramp 11
The variation for generating angle is moved around axis.
The operation principle of the utility model：During work, material is placed on vari ramp by operator, and shake rocking arm makes adjustable
Inclined plate lifts to certain height, when material slides, stops shaking rocking arm, observes the quarter on graduated scale at this time in the side of pedestal
Degree.
The beneficial effects of the utility model：With good intuitive, it can accurately show that the opposite of subjects is slided
Frictional force.By the way of ball-screw-transmission, continuity is good, and can carry out the fine tuning of angle, suitable for experimental study.
And the device is detachably assembled, occupied little space, is easy to carry, is at low cost.In addition the configuration of the present invention is simple, it is easy to operate,

Description of the drawings
Fig. 1 is the three dimensional structure diagram of the utility model；
Fig. 2 is the left view of the utility model；
In Fig. 1 respectively marked as：1 it is rocking arm, 2 be rocking arm sleeve, 3 be pedestal, 4 be dial scale, 5 be fixed block, 6 is spiral shell
It is female, 7 be connecting rod, 8 be pedestal sliding block, 9 be ball-screw, 10 be supporting rod, 11 be vari ramp.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment 1：As shown in Figure 1, a kind of material friction coefficient measurement device, including pedestal 3, ball-screw 9, nut 6, shake
Bar 1, dial scale 4, vari ramp 11 and supporting rod 10；
The pedestal 3 is made of two identical L-type supports, the parallel placement in the same direction of two L-type supports, the two sides of bottom
Between connected by connecting rod 7, ball-screw 9 is respectively fixed in the L-type support of both sides, 9 one end of ball-screw is fixed on L-type
The top of stent vertical edge, the other end are fixed on the base of L-type support；The upper end of ball-screw 9, which is fixed with, rotatably shakes
Bar 1 is arranged with the nut 6 coordinated with it on ball-screw 9, and nut 6 is connected with fixed block 5, is connected between the fixed block 5 of both sides
Supporting rod 10, vari ramp 11 are placed on supporting rod 10, and the bottom of vari ramp 11 is fixed between the L-type support of both sides,
