Force feedback protective device.
The utility model includes cross bar, gear, rack, nozzle, high-pressure nozzle, it is characterised in that：One end of cross bar is fixed
On suspension, it is equipped with rack close to hanger segment in cross bar, gear is located at below rack and engages；The left end of high-pressure nozzle
Nozzle is installed, boss sleeve is fixed on high-pressure nozzle, and spring is located on boss sleeve, and the right end of high-pressure nozzle passes through suspension
And it is fixed with collet；Displacement sensor is mounted on suspension, and pull rod is connect with collet, and suspension lower end is equipped with roller.
The rack is sleeve-shaped, can be on cross bar toward polyslip.
The roller can be rolled along track, to ensure that suspension steadily moves.
Simultaneously waterjet calculated impact reactive force can be detected automatically by the displacement sensor, and according to reaction force
Size, pass through the jet length between the gear, rackwork dynamic regulation nozzle and body surface.
The utility model has the advantage of：The auto-feed that high-pressure nozzle can be achieved, can detect water jet recoil strength in real time
Variation, and automatically adjust jet length.As a result of spring as buffering, the stability and reliability of device are improved,
For different operating modes, the spring of replaceable difference coefficient of elasticity improves the applicability of device.Use displacement sensor inspection
The variable quantity of spring is surveyed, it is easy for installation, protect mechanical structure from the destruction of high-pressure water jet recoil strength, detecting displacement in real time can
To help control system quick response, control accuracy is improved.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig.1,2, the utility model includes cross bar 1, gear 2, rack 3, nozzle 4, high-pressure nozzle 5, the utility model
One end of cross bar 1 is fixed on suspension 8, and rack 3 is equipped with close to 8 sections of suspension in cross bar 1, gear 2 be located at 3 lower section of rack and and its
Engagement；The left end of high-pressure nozzle 5 is equipped with nozzle 4, and boss sleeve 6 is fixed on high-pressure nozzle 5, and spring 7 is located at boss set
On cylinder 6, the right end of high-pressure nozzle 5 passes through suspension 8 and is fixed with collet 10；Displacement sensor 9 is mounted on suspension 8, pull rod
It is connect with collet 10,8 lower end of suspension is equipped with roller 11.
Cross bar 1 is fixed, and gear 2 is driven by servo motor, and rack 3 is in sleeve-shaped, can be on cross bar 1 toward polyslip, rack 3
It is fixed with suspension 8.The left end of high-pressure nozzle 5 is equipped with nozzle 4, and boss sleeve 6 is fixed with high-pressure nozzle 5, and withstands spring 7.
The other end of high-pressure nozzle 5 passes through suspension 8 and is fixed with collet 10.Displacement sensor 9 is mounted on suspension 8, pull rod and folder
First 10 connection.Suspension lower end is mounted with the roller 11 rolled along guide rail, is moved with ensureing that suspension 8 is linearly stablized.
When needing to adjust the spacing between nozzle 4 and body surface, if gear 2 rotates counterclockwise, engage
Rack 3 will move downward, since suspension 8 and rack 3 are fixed, suspension 8 also moves downward, high under the drive of suspension 8
Pressure jet pipe 5 moves downward, and makes nozzle 4 close to body surface.Similarly, if gear 2 rotates clockwise, nozzle 4 will be to separate
It is moved by the direction of injection object.
After adjusting spacing, the position of fixed suspension 8, when pressure water jets impact is to body surface, impact force meeting
Reaction force is generated to high-pressure nozzle 5, to push high-pressure nozzle 5 to move right, at this point, boss sleeve 6 is by compressed spring 7,
According to the principle of active force and reaction force, the decrement by measuring spring 7 can both calculate anti-force suffered by high-pressure nozzle
Size, then judge the variation of pressure water jets impact power indirectly.If the decrement △ X of spring, it is according to the elasticity of spring
The size △ X of number k and decrement, can calculate size F=k △ X of current water jet recoil strength.
The decrement of spring 7 can be detected by displacement sensor 9, and specific testing principle is：The installation of displacement sensor 9 is solid
It is scheduled on 8 right side of suspension, collet 10 is fixed on 5 right end of high-pressure nozzle, and the pull rod of displacement sensor 9 is connect with collet 10, works as high pressure
When jet pipe 5 moves right, collet 10 is driven to move right, to pull the pull rod of displacement sensor 9 to move right, according to displacement
The measuring principle of sensor, the variation of pull rod displacement can lead to the variation of displacement transducer signal, to directly reflect spring 7
Telescopic variation amount.Pass through control system numerical computations, you can obtain the size F of water jet recoil strength.
In the case of water flow pressure, stability of flow, when recoil strength F is more than limit value, rack and pinion mechanism will be adjusted automatically
The spacing between nozzle 4 and object is saved, to ensure that pressure water jets impact power works in the range for stablizing safety.
The content of the utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and to any equivalent transformation that technical solutions of the utility model are taken, be the claim institute of the utility model
