When power transmission shaft is connected by a torsionspring with flexible axle, operating theater instruments is when operation, between the light-permeable of everywhere
The width of gap equally changes.
In detail, for aforesaid way 2:
In mode 2, at least one spring described can be at least one compression spring.Therefore, in one reality of the present invention
Execute in example, in described bossing and the junction of described groove part, at least one compression spring can be passed through, by described convex

t8Time period in output pulse signal, be light be L again by width2Light-permeable gap time, pulse signal generating unit is raw
The pulse signal become.
In detail, for the cutter head normal situation of operation:
When cutter head operation is normally so that the output of cutter head invariablenes turning speed, processor power is constant, stretching of two compression springs
Contracting state does not changes.Therefore the pulse period of the pulse signal shown in Fig. 5 can be: (t5-t1)、(t6-t2)、(t7-
t3)、(t8-t4Any one in).Wherein, (t5-t1)=(t6-t2)=(t7-t3)=(t8-t4).Accordingly, permissible
The current rotating speed calculating cutter head can be 1/ (t5-t1)、1/(t6-t2)、1/(t7-t3)、1/(t8-t4Any one in)
Kind.
In detail, for the situation of cutter head operation exception:
For example, in an embodiment of the invention, owing to processor output power is fixed, therefore the rotating speed of flexible axle is solid
Fixed.Assume that the flexible axle in Fig. 4 rotates clockwise, when the rotating speed of the power transmission shaft being connected with cutter head changes, when usually diminishing,
The compression spring of the light-permeable gap location of top in Fig. 3 can be caused to be in compressive state, and the light-permeable gap above this subtracts relatively
Little, the compression spring of the light-permeable gap location of lower section is in extended state, and the light-permeable gap above this increases relatively.This change
Change can cause the pulse period (t in Fig. 55-t1), pulse period (t6-t2), pulse period (t7-t3), the pulse period
(t8-t4) become big.And due to the change of telescopic spring state so that t5And t8Corresponding concrete light-permeable position changes, t6
And t7Corresponding concrete light-permeable position does not changes, so that pulse period (t5-t1) more than pulse period (t6-
t2), pulse period (t8-t4) more than pulse period (t7-t3).When not changing due to the current rotating speed of cutter head, compress bullet
The retracted position of spring equally changes, therefore based on arbitrary concrete light-permeable position not changed, can calculate cutter
The current rotating speed of head.It is consequently possible to calculate the current rotating speed going out cutter head can be 1/ (t6-t2) or 1/ (t7-t3)。
Additionally, the light-permeable gap in the left side that again may be by Fig. 3, so that light-sensitive element receives optical transmitting set and launches
Light.
Correspondingly, when flexible axle rotation direction is for rotating counterclockwise, pulsewidth position corresponding to each light-permeable gap can occur
Change, therefore another kind of pulse signal can be generated.Realize principle based on same, according to this another kind pulse signal, equally may be used
Can be 1/ (t to calculate the current rotating speed of cutter head6-t2) or 1/ (t7-t3)。
Owing to Fig. 3 being the groove part of power transmission shaft is connected with the bossing of flexible axle, therefore when this connected mode is for passing
When the bossing of moving axis is connected with the groove part of flexible axle, same realize principle, according to the corresponding arteries and veins generated based on above-mentioned
Rushing signal, the current rotating speed equally calculating cutter head can be 1/ (t5-t1) or 1/ (t8-t4).Due to can based on
One realizes principle, thus the present embodiment therefore not to repeat here.
Understand from the above mentioned, power transmission shaft and flexible axle can be connected by a torsionspring or at least one compression spring,
And both junctions can include at the attachment structure of at least one bossing and groove part, and each attachment structure
At least one light-permeable gap, place can be included.This implementation can not only connect power transmission shaft and flexible axle, in order to processor
The transmission of output power, by can generating can reflect the current rotating speed of cutter head the most in real time based on arbitrary light-permeable gap
Pulse signal, thus it is of value to the processor real-time accurate measurements to cutter head rotating speed, and improve the accuracy of operation technique.
Additionally, for aforesaid way 2, be to be connected by a torsionspring between power transmission shaft and flexible axle, rather than pass through
When at least one compression spring is connected, for arbitrary light-permeable gap of the attachment structure of bossing and groove part, equally
Can be by the pulse period to judge the current rotating speed of cutter head.
As shown in Figure 6, one embodiment of the invention provides the cutter head rotating speed of a kind of operating theater instruments and determines method, can wrap
Include following steps:
Step 901: described cutter head is connected with power transmission shaft, described power transmission shaft is connected by least one spring with flexible axle,
