Below in conjunction with accompanying drawing, a use procedure of the present invention is described:
In the present embodiment, power measurement of the present invention is designed to handwheel 20 with force loading device and rotates counterclockwise, and female 13 forwards of controlled throwing move and Compress Spring 15; Under original state, screw 13 contacts with the first thrust metal 9, and now spring 15 does not stress.
1, specified force is measured:
First the original state of device is regulated.Slowly rotate counterclockwise handwheel 20, make worm screw 19 drive worm gear 18 to rotate counterclockwise, under the effect of the first bevel planet gear 34 and the second bevel planet gear 35, the first center bevel gear 30 and the second center bevel gear 31 have the trend of rotation; Because rotating, the first center bevel gear 30 can drive ball-screw 14 to rotate, thereby make screw 13 forwards move Compress Spring 15, but under the bounce-back drag effect of spring 15, the athletic meeting of screw 13 and the first center bevel gear 30 is stoped, therefore keep transfixion; For the second center bevel gear 31, because spur rack 42 is not interrupted in direction of motion, so the second center bevel gear 31 can rotate, thereby drive spur rack 42 to move forward by rotating shaft 40 and spur gear 41, and drive force rod 53 to move to protract, until the first tooth bar clamping seat 43 contacts with the first guide pillar supporting seat 51.At this moment, the original state of device regulates complete, can specify force measurement.
Starting specified force measures.Testing force is applied on force rod 53, and now force rod 53 can move backward, moves backward, and drive the second center bevel gear 31 to rotate by spur gear 41 and rotating shaft 40 thereby order about spur rack 42; Because 18 pairs of worm screws 19 of worm gear have self-locking action, worm gear 18 can not rotate.So, the second center bevel gear 31 drives the first center bevel gear 30 to rotate by the first bevel planet gear 34 and the second bevel planet gear 35, and driving thrust plate 11 forwards to move and then Compress Spring 15 by ball-screw 14 and screw 13, pointer 12 is followed thrust plate 11 and is moved.Spring 15 bounce in compression process can linearly increase, and causes the resistance of force rod 53 linearly to increase, and when spring 15 bounces and testing force equal and opposite in direction, device of the present invention will be in equilibrium state.At this moment, the indicated scale value of pointer 12 is the size of testing force.
2, specified object is carried out to power loading and unloading:
First the original state of device is regulated.Slowly rotate clockwise handwheel 20, make worm screw 19 drive worm gear 18 to clockwise rotate, under the effect of the first bevel planet gear 34 and the second bevel planet gear 35, the first center bevel gear 30 and the second center bevel gear 31 have the trend of rotation; Because the first center bevel gear 30 rotates, can drive ball-screw 14 to rotate, screw 13 is oppositely moved, and now screw 13 contact, and can not move with the first thrust metal 9, therefore the first center bevel gear 30 can not rotate; For the second center bevel gear 31, because spur rack 42 is not interrupted in direction of motion, so the second center bevel gear 31 can rotate, thereby drive spur rack 42 to move backward by rotating shaft 40 and spur gear 41, until the second tooth bar clamping seat 44 contacts with the second guide pillar supporting seat 52.At this moment, the original state of device regulates complete, can carry out power loading and unloading to specified object.
Start specified object to carry out power loading.Specified object is contacted with the force rod 53 of apparatus of the present invention, now slowly rotate counterclockwise handwheel 20, make worm screw 19 drive worm gear 18 to rotate counterclockwise, under the effect of the first bevel planet gear 34 and the second bevel planet gear 35, the first center bevel gear 30 and the second center bevel gear 31 have the trend of rotation; The second center bevel gear 31 imposes on force rod 53 by rotating shaft 40, spur gear 41 and spur rack 42 by power, by 53 pairs of specified object of force rod, applies power load, but is subject to the restriction of specified object, and the second center bevel gear 31 keeps transfixion; Meanwhile, rotating counterclockwise of worm gear 18 drives the first center bevel gear 30 to rotate, and by ball-screw 14 and screw 13 drive thrust plates 11 and on pointer 12 forwards move, impel spring 15 compressions; The bounce of spring 15 passes to the first center bevel gear 30 via the effect of thrust plate 11, screw 13 and ball-screw 14; Now, in the slow rotation process of worm gear 18, the first center bevel gear 30 and the second center bevel gear 31 keep stress balance, the first center bevel gear 30 passes to the second center bevel gear 31 by moment of torsion, and is applied in specified object by rotating shaft 40, spur gear 41, spur rack 42 and force rod 53.In sum, the compression bounce of spring 15 acting force suffered with specified object is corresponding one by one, and stressed in apparatus of the present invention is balance, continue slowly to rotate counterclockwise handwheel 20, worm gear 18 can continue to rotate counterclockwise, make spring 15 constantly compressed, and by the first center bevel gear 30, the first bevel planet gear 34, the second bevel planet gear 35, the second center bevel gear 31, rotating shaft 40, spur gear 41, spur rack 42 and force rod 53, the acting force of spring 15 is imposed on to specified object, the continuing to increase of realizable force load.In this process, the value of the pointer 12 power load that indication applies in real time.
Carry out the unloading of power load.Slowly rotate clockwise handwheel 20, make worm screw 19 drive worm gear 18 to clockwise rotate, contrary with power loading procedure, thrust plate 11 oppositely moves, and compressed spring 15 restores gradually, until screw 13 contacts with the first thrust metal 9.In this process, the power load that 53 pairs of specified object of force rod apply reduces gradually until be zero, the unloading of realizable force load.
