Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises frame 100, and frame 100 is L-shaped, and the upper end of frame 100 is provided with cylinder 8, and the outer end of frame 100 is provided with bottom roll 1, and the knuckle place of frame 100 is provided with drum to test 4, and the diameter of drum to test 4 is 25 millimeters.4 axial uniform upper traction belts 7 are around connecting upper cylinder 8, and the outer end of upper traction belt 7 connects respectively upper grip 6, and upper cylinder 8 connects upper motor 11 by upper two-way electomagnetic clutch 10 and upper magnetic powder brake 9.Four axial uniform lower traction belts 2 are around connecting bottom roll 1, the outer end of lower traction belt 2 connects respectively lower chuck 3, bottom roll 1 connects lower motor 14 by lower two-way electomagnetic clutch 13 and lower magnetic powder brake 12, upper motor 11 and lower motor 14 are buncher, adjust its rotating speed and make the linear velocity of cylinder 8 and bottom roll 1 reach 125 mm/second.The other upper sensor 16 that is provided with of upper cylinder 8, the other lower sensor 15 that is provided with of bottom roll 1.
During test, electric pad 5 is at right angles walked around drum to test 4, and the two ends of electric pad 5 are clamped by upper grip 6 and lower chuck 3 respectively, thereby electric pad 5 is fixed between lower traction belt 2 and upper traction belt 7.in startup, motor 11, go up simultaneously two-way electomagnetic clutch 10 actions and (make drum shaft and 11 combinations of upper motor, throw off with upper magnetic powder brake 9), same two-way electomagnetic clutch 13 at present also moves and (bottom roll axle and lower motor 14 is thrown off, with lower magnetic powder brake 12 combinations), upper motor 11 drives when upward cylinder 8 turns clockwise, lower magnetic powder brake 12 energising work, bottom roll 1 is produced a damping (this damping can be controlled by the electric weight of regulating lower magnetic powder brake 12), like this, electric pad 5 is just under stressed state, walk around the drum to test 4 of 25 millimeters of diameters, with 125 mm/second speed along level and vertically upward direction move, can control the opening and closing of the machine of powering on 11 and lower motor 14 by upper sensor 16 and lower sensor 15.when electric pad 5 is done the counter motion test, after upper motor 11 cuts out, lower motor 14 starts immediately, (make bottom roll axle and lower motor 14 combinations with two-way electomagnetic clutch 13 actions at present, throw off with lower magnetic powder brake 12), going up simultaneously two-way electomagnetic clutch 10 also moves and (drum shaft and upper motor 11 is thrown off, with upper magnetic powder brake 9 combinations), when lower motor 14 drive bottom rolls 1 are rotated counterclockwise, upper magnetic powder brake 9 energising work, upper cylinder 8 is produced a damping (this damping can be controlled by the electric weight of regulating upper magnetic powder brake 9), like this, electric pad 5 is again under stressed state, walking around drum to test 4 moves along level and vertical downward direction with 125 mm/second speed, lower so forward and reverse periodic duty 2000 times, can complete test.
