Background technique
As science and technology is showing improvement or progress day by day, the reading of e-book is more and more popular, and electronic writing material stores for easy to carry, books
The advantages that amount is big, page turning facilitates.But paper book also has long-standing necessity.Since copyright problem causes many books to only have
Papery version, people for being used for a long time, the books that need to conscientiously read, still preference paper book；E-book screen size is smaller,
Font is smaller, reads eyes and is easy fatigue；Especially for Instrumentalist when playing in face of music score, eyes are relative to music score
Be it is dynamic and distance farther out, eyes be easier fatigue, more need the music score book of papery.It is found by investigation, at present papery
Book is in occasions such as school, instrument playings, when classics are read or studied carefully or mainstream.Generally speaking, when following longer
In phase, paper book reading will be basic reading method.
But paper book, which is read, stablizes books sometimes for hand, and reading hand for a long time can be relatively more tired.When instrument playing, music score
Book is stood upright on music rack, and page loses gravity and needs to fix；But existing various fixing means cause page turning difficulty again,
Page turning could be completed by needing several movements of both hands.Therefore, one kind is needed to have page fixed function, page turning more easily in the market
Equipment.
Market survey is the results show that currently on the market without this kind of equipment for common paper book, while in market tune
Middle discovery is looked into, even if manual page turning, as long as equipment can be automatically performed the pressure to page, release pressurized state, avoid and stir
The mechanical actions such as page, realize similar naturally manual page turning process of the page under no any page turning obstacle, can obtain
The market demand.
During manual page turning, page and the pressure point of accessible page turning equipment is pressed to be unable to opponent and page and have interference,
Be to the action request of pressure point in technical solution: the mechanical caging-released under pressure point pressurized state is ramped-is rotated in the forward direction
Stop (motion range that hand and the page stirred get over over-voltage page and accessible page turning equipment pressure point at this time)-reversed rotation after 90 °
Turn 90 °-straight line decline-pushing and mechanical caging to keep pressure point pressurized state；Either: releasing the machine under pressure point pressurized state
Tool locking-rotation rises 90 °, and (hand and the page stirred get over the movement model of over-voltage page and accessible page turning equipment pressure point at this time
Enclose)-decline-pushing and mechanical caging are rotated to keep pressure point pressurized state.The mechanical response of pressure point is fast, can follow page turning
Hand acts in time.
For " release pressure point pressurized state under mechanical caging-ramp-rotating in the forward direction-reversely rotate-straight line under
Drop-pushing and mechanical caging are to keep pressure point pressurized state " mechanical device, a kind of my invention's patent " realization lifting rotation
The mechanical mechanism of the mechanical mechanism of movement " (ZL 2,013 1 0490632.6) claim 1, can satisfy " ramp-just
To rotation-reverse rotation-straight line decline-pushing " requirement of this partial function.
Found additionally by investigation, presently, there are mechanical equipment, Yao Shixian " ramps-rotates in the forward direction-reversed rotation
Turn-straight line decline-pushing " movement, and position locking and the holding to pressure object pressure are realized after disconnecting power, all make
With guide rail+self-locking screw rod+turntable+engine, guide rail+non-self-lock-ing screw rod+turntable+engine+brake, non-screw rod straight-line transmitting motivation
Structure+turntable+brake scheme.These schemes have these advantages: first, it is such as oriented to using linear guide, ball-screw passes
Dynamic, driving motor band code-disc, positioning accuracy is very high, and mechanical efficiency is high；Second, due to using guide rail to be oriented to and being carried, bear
Loading capability is high；Third, due to using independent turntable to realize rotation function, precision and high load capacity.
Technical problem
Since existing machinery equipment will realize the mechanical movement of two dimensions of lifting rotation, substantially used in translational motion
Guide rail uses turntable in rotary motion；It reduce the dynamic response capability of equipment, the volume that increases equipment, complicated journey
Degree and cost, reduce the reliability of equipment.
If existing equipment will keep other being brought to ask the pressure of pressure object under non-power state
Topic.
Non-self-lock-ing screw drive is such as used, then is had the disadvantage that: first, need to add brake gear and its control function,
Need additional installation space；Second, the mutual conversion process between the braking state and releasing braking state of brake gear needs
A few tens of milliseconds or longer time are not able to satisfy higher time response requirement and increase operation power consumption；Third needs periodically to tie up
Shield, to guarantee stability and reliability；4th, brake gear increases the complexity and cost of equipment.
Such as use self-locking screw drive, lead angle should be less than be equal to equivalent friction angle (screw rod, the lead angle of swivel nut are small
When being equal to equivalent friction angle, spiral shell is sleeved on the screw rod with axial self-locking performance), but at this time since lead angle is smaller, screw rod
Transmission efficiency is lower, this improves the requirement to engine power, so as to cause the increasing of equipment volume, operation power consumption and cost
Add.
Therefore, Millisecond time response is being required, transmission efficiency is higher, applies pressure to pressure object and in unpowered feelings
Application that can be self-locking under condition, for example, pressure page and accessible page turning equipment, it is necessary to some new mechanical devices are researched and developed,
To meet these requirements.
