Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
The drawbacks of present invention is for sports platform unbearable relatively larger transverse power proposes a kind of have hanging down for bearing capacity
To motion platform, which drives lead screw and sliding block, it can be achieved that the space of loading force output position is automatically fixed by motor
Position.In addition, platform is provided with active clearance and passive gap, when positioning at an arbitrary position, positioning bolt generates pretightning force, will draw
The deformation of spring is played, and then reduces passive gap, until pulley base and load-bearing frame are in close contact, that is, load-bearing frame are realized and holds
External force is carried, lead screw is avoided and bears cross force.After pretightning force releasing, the automatic control of position can be realized.
Specifically, a kind of catenary motion platform for having bearing capacity of the present invention, comprising:
Actuator 1；Entrance hole 2；Import pulley 3；Load-bearing frame 4；Wirerope 5；Export pulley 6；Guide blot 7；Pulley
Seat 8；Motor support base 9；Motor 10；Bearing hole 11；Spring 12；Load bolt positioning hole 13；Slide plate 14；Sliding block 15；Load bolt
16；Leadout hole 17；Lead screw 18；Leading screw bearing 19；Slide plate pilot hole 20；Passive gap 21；Active clearance 22；Pulley base pilot hole
23；Positioning guide hole 24；Guide blot location hole 25.
Wherein, actuator 1 is force application part, and the extension end of actuator 1 is fixedly connected with wirerope 5.
5 one end of wirerope is fixedly connected with actuator 1, and enters load-bearing frame 4 by the entrance hole 2 on load-bearing frame 4
It is internal.Wirerope 5 generates the change in direction by importing pulley 3, and then is further turned to by export pulley 6.After steering
Wirerope 5 is by the pulley base pilot hole 23 on pulley base 8, the slide plate pilot hole 20 on slide plate 14, then by load-bearing frame 4
On leadout hole 17 be pierced by, and be connected with external product.
The load-bearing frame 4 is cylindrical frame structure, and material is steel, is provided with entrance hole 2, leadout hole 17, positioning
Pilot hole 24；Wherein, entrance hole 2 is located at the side bottom position of load-bearing frame 4；Leadout hole 17 is oblong structure, is located at side
Face position；Positioning guide hole 24 and leadout hole 17 are located at same side.
When the extension bar of actuator 1 is shunk, wirerope 5 is tightened, and the effect of pulling force F is generated to outside manufacture.
Motor 10 is located inside load-bearing frame 4, and fixed on motor support base 9.The extension end of motor 10 passes through bearing hole
11 are fixedly connected with lead screw 18, which can be key connection, pin connection, Bolted Flanged Connection etc..Lead screw 18 it is another
End is connect with leading screw bearing 19, and leading screw bearing 19 is fixed on load-bearing frame 4.
Sliding block 15 is provided on lead screw 18, when motor 10 drives lead screw 18 to rotate, sliding block 15 realizes vertical linear motion.
Sliding block 15 is fixedly connected with slide plate 14, and realization moves synchronously；
Export pulley 6 is fixedly mounted on pulley base 8, and the material of pulley base 8 is steel, and it is fixed to be additionally provided with guide blot thereon
Position hole 25, load bolt positioning hole 13；
Guide blot 7 passes through 12 center of spring by the guide blot location hole 25 on pulley base 8, solid with slide plate 14
It is fixed to be connected；
The material of slide plate 14 is steel, and centre is provided with slide plate pilot hole 20 thereon；
The diameter of guide blot location hole 25 is greater than the diameter of guide blot 7, and therefore, in stress, pulley base 8 can be along leading
To the axial free movement of bolt 7；
Pulley base 8 and slide plate 14 form active clearance 22, and when 12 forced compression of spring, active clearance 22 will reduce；
Pulley base 8 and load-bearing frame 4 form passive gap 21, and the movement of pulley base 8 equally changes passive gap 21
Size；
As it can be seen that motor 10 drives lead screw 18, and then sliding block 15, slide plate 14, pulley base 8, export pulley 6 is driven to do straight line fortune
Move the movement, it can be achieved that space any position.After reaching designated position, load bolt 16 passes through the positioning on load-bearing frame 4
Pilot hole 24 is connect with load bolt positioning hole 13.In screwing operations, bearing block 8 compresses spring 12, active clearance 22,
Passive gap 21 reduces simultaneously, until bearing block 8 and load-bearing frame 4 are in close contact.The pretightning force of load bolt 16 is continued growing,
12 generation of spring will not be acted on.When applying basic load F, wirerope 5 conducts power to bearing block 8, and then conducts extremely
Load-bearing frame 4, and slide plate 14, sliding block 15, lead screw 18 be by the effect of basic load F, namely avoids lead screw 18 by larger
Cross force.As it can be seen that cross force suffered by lead screw 18 depends entirely on the elastic force that the compression of spring 12 generates, therefore spring can be passed through
Stiffness tuning.
When specific works:
(1) it is instructed to the control system input position of motor 10, motor 10 generates rotary motion, drives lead screw 18, sliding block
15, slide plate 14, pulley base 6 move to designated position, that is, define the extended position of wirerope 5.
(2) after reaching designated position, load bolt 16 screws in load bolt positioning hole 13, pulley by positioning guide hole 24
Seat 8 moves under the pretightning force effect of load bolt 16, and causes the compression of spring 12 and active clearance 22, passive gap 21
Reduction.Load bolt 16 further screws, until passive gap 21 is zero, pulley base 8 is fitted closely with load-bearing frame 4.It is complete
After this process, the elastic force that lead screw 18 is only generated by spring 12 is acted on.
(3) 1 extension end of actuator is stretched out, and is connected with wirerope 5.Another extension end of wirerope 5 passes through load-bearing frame 4
On leadout hole 17 be connected with external product.
(4) extension end of actuator 1 is shunk, and drives wirerope 5, applies pulling force F to external production portion.During this, because
Pulley base 8 is fixedly connected with load-bearing frame 4, and the power on wirerope 5 directly passes through export pulley 6, pulley base 8 is transferred to load frame
Frame 4, without being had an impact to lead screw 18.
(5) after the test, 1 extension end of actuator is stretched out, and realizes unloading, and F becomes zero.
(6) load bolt 16 is reversely rotated, until screwing out completely.Pulley base 8 restores under the active force of spring 12 to first
Beginning position.
(7) motor 10 starts, and export pulley 6 is driven to move to initial position, and preparation is tested next time.
