Shaft axially moves in the case where cooperating with screw thread vertical plate internal thread hole, and turning for scroll spring inner end is resetted in moving process
Axis fixture block, as flywheel rotates, resets the annular groove fixture block of scroll spring outer end originally by the frictional force of annular groove under the drive of card slot
Limit resets scroll spring by compressed energy-storage；The position of engagement of flywheel gear and the speed cone conical surface is with flywheel shaft simultaneously
It moves axially and changes, the variation of the position of engagement causes the transmission ratio between deceleration shaft and flywheel shaft to change.When winged
When wheel gear is close to speed cone maximum radius position, the compression degree of scroll spring is resetted close to compression limit, flywheel shaft

Turn.The first knife grinding mechanism, the second knife grinding mechanism, third knife grinding mechanism and chuck, can be to workpiece by cooperating in the present invention
Carry out multiple degrees of freedom processing work.
When workpiece is during carrying out processing work, reset motor is in self-locking state, is placed due to the location of workpiece
It is unreasonable will lead to chuck and rotation occur have some setbacks or when stuck phenomenon, then the rotation of chuck gear ring also will receive rotation not
The influence of benefit.Since the rotation of chuck gear ring is by driving rotary force F0 provided by gear to realize, according to the mutual of power
Effect, when chuck gear ring rotation not up time can in turn to driving gear one bigger reverse rotational force F1.When reversed rotation
Turn that the direction of driving gear reverse rotation power F1 can be forced to swing when power F1 is greater than the elastic force of reset spring, arc balance also can
Certain radian is swung, during the swing of arc balance, since reseting gear is by self-locking reset electric machine spacing, so that
Reseting gear and arc balance are mutually stuck, and reseting gear also follows arc balance to swing, and reset motor along arc to drive
Shape guide rail is swung.Reduction gearing engages under the swing of arc balance with chuck gear ring simultaneously, by the excess energy of chuck gear ring
Speed cone is passed to by transmission gear, flywheel is then passed to by speed cone again, buffering chuck is realized, reduces to grinding machine machine
The purpose of tool damage and protection workpiece.After chuck revolving speed is reduced to zero, resets, drive in the drive arc lower balance for resetting motor
Moving gear engages again with chuck gear ring, and reduction gearing is separated with chuck gear ring.Maximum of the flywheel gear close to speed cone at this time
At radius, speed cone is unable to drive the rotation of flywheel shaft, and annular groove fixture block restores static under the frictional force effect of annular groove, and flywheel turns
Axis is resetted in the case where the inner end of reset spring drives.
Speed cone is passed to by transmission gear in the excess energy of chuck gear ring, is then passed to again by speed cone winged
During wheel, originally engaged at flywheel gear and the least radius of speed cone；Deceleration shaft is started by lesser transmission ratio
Static flywheel, such design can allow deceleration shaft easily to drive flywheel, prevent excessive fly wheel start-up resistance from destroying
The tooth of reduction gearing and transmission gear.Screw thread with the lasting transmitting of the rotation function of speed cone, in flywheel gear shaft
Under the cooperation of screw thread vertical plate, flywheel gear is to moving in rotation at speed cone maximum radius.During entire moving in rotation, with
Transmission ratio between deceleration shaft and flywheel shaft increases, and the revolving speed of flywheel gear also and then increases, and the revolving speed of flywheel is also followed
Increase, the increased purpose of transmission ratio is that the flywheel having been started up is allowed quickly to absorb the kinetic energy of chuck.When flywheel gear rotates
When being moved at the maximum radius of speed cone, screw thread end and screw thread vertical plate just in flywheel gear shaft are detached from, then flying
Wheel gear will be rotationally moved no longer, but at the maximum radius of speed cone around flywheel gear shaft axis rotation after
The continuous energy for absorbing chuck.
When workpiece accidentally occurs jeopardizing finger during carrying out processing work, finger will receive extruding
Injury, the torque moment for being subject to chuck increase by a small margin.Inside receives the torque of moment equipped with the chuck of torque sensor
Signal is delivered separately to power unit, electromagnetic switch by three kinds of approach and resets motor, to make in work by variable signal
Grinding machine stop working in a very short period of time, play the role of protect finger.Three kinds make the approach that grinding machine stops working: the first
It is that signal is passed into unit power, unit power is made to stop working immediately；Second is that signal is passed to electromagnetic switch, is made
Electromagnetic switch stops the power transmission between power shaft and power gear shaft；The third is that signal is passed to reset electricity
Machine makes to reset motor disengaging self-locking state, then reseting gear will not play the role of resetting the limit of arc balance at this time
Elastic force F3 on leaf spring swings arc balance to the direction away from restoration spring, to drive gear and chuck gear ring de-
From reduction gearing is engaged with chuck gear ring, then the remaining kinetic energy of chuck and chuck gear ring passes through reduction gearing and transmission gear
Speed cone is passed to, kinetic energy entrained by speed cone passes to flywheel through flywheel gear and flywheel shaft again, realizes chuck and stops
The purpose only to work.
Relative to traditional grinding machine technology, the present invention solve because the unreasonable appearance of the location of workpiece grinding machine work it is unsmooth or
Stuck phenomenon, the purpose realized buffering chuck, reduce to grinding machine mechanical damage and protect workpiece, extends the use of grinding machine
Service life；Three kinds of Approaches to protection are devised in the present invention simultaneously, any one in three kinds of Approaches to protection can all make grinding machine extremely short
It stops working in time, plays the personal safety of protection operator, substantially increase the safety that grinding machine uses.The letter of its structure
It is single compact, it is highly-safe, there is preferable practical effect.

It is unreasonable will lead to chuck 4 and rotation occur have some setbacks or when stuck phenomenon, then the rotation of chuck gear ring 3 also will receive rotation
Turn detrimental effect.As shown in the Aa in Figure 18, since the rotation of chuck gear ring 3 is by rotation provided by driving gear 17
What power F0 was realized, the reduction gearing as shown in the Ab in Figure 18 and chuck gear ring are detached from, according to the interaction of power, when chuck gear ring
Up time can not give driving gear 17 1 bigger reverse rotational force F1 in turn for 3 rotation.As shown in the Ba in Figure 18, when anti-
The direction of driving 17 reverse rotation power F1 of gear can be forced to swing when being greater than the elastic force of reset spring 30 to rotary force F1, arc
Balance 15 can also swing certain radian, during the swing of arc balance 15, since reseting gear 24 is answered by self-locking
Position motor 22 limits, so that reseting gear 24 is mutually stuck with arc balance 15, reseting gear 24 also follows arc balance 15 to put
It is dynamic, it is swung to drive and reset motor 22 along arc-shaped guide rail 21.As shown in the Bb in Figure 18, while reduction gearing 14 is in arc
It is engaged under the swing of balance 15 with chuck gear ring 3, the excess energy of chuck gear ring 3 is passed into speed cone by transmission gear 19
31, flywheel 16 is then passed to by speed cone 31 again, buffering chuck 4 is realized, reduces to grinding machine mechanical damage and protection work
The purpose of part.After 4 revolving speed of chuck is reduced to zero, reset motor 22 drive arc lower balance 15 reset, driving gear 17 with
Chuck gear ring 3 engages again, and reduction gearing 14 is separated with chuck gear ring 3.As shown in the d and e of Figure 22, flywheel gear 37 is connect at this time

Speed cone 31 is passed to by transmission gear 19 in the excess energy of chuck gear ring 3, then passes through speed cone 31 again
During passing to flywheel 16, originally engaged at flywheel gear 37 and the least radius of speed cone 31；Deceleration shaft 27 passes through
Lesser transmission ratio starts static flywheel 16, and such design can allow deceleration shaft 27 easily to drive flywheel 16, prevent
Excessive 16 resistance of start of flywheel destroys the tooth of reduction gearing 14 and transmission gear 19.As the rotation function of speed cone 31 is held
Resume and pass, in 37 shaft of flywheel gear screw thread and screw thread vertical plate 35 cooperate under, flywheel gear 37 to speed cone 31 maximum half
Moving in rotation at diameter.During entire moving in rotation, as the transmission ratio between deceleration shaft 27 and flywheel shaft 36 increases,
The revolving speed of flywheel gear 37 also and then increases, and the revolving speed of flywheel 16 also and then increases, and the increased purpose of transmission ratio is to allow
The flywheel 16 of starting quickly absorbs the kinetic energy of chuck 4.As shown in fig. 21b, when flywheel gear 37 is rotatably moved to speed cone 31
Maximum radius at when, just the screw thread end in 37 shaft of flywheel gear and screw thread vertical plate 35 are detached from, then flywheel gear 37
It will no longer rotationally move, but rotate and continue around the axis of 37 shaft of flywheel gear at the maximum radius of speed cone 31
Absorb the energy of chuck 4.
When workpiece accidentally occurs jeopardizing finger during carrying out processing work, finger will receive extruding
Injury, the torque moment for being subject to chuck 4 increase by a small margin.As shown in figure 20, the internal chuck 4 equipped with torque sensor receives
To the change in torque signal of moment, signal is delivered separately to power unit 1, electromagnetic switch 10 by three kinds of approach and resets electricity
Machine 22 plays the role of protecting finger so that the grinding machine in work be made to stop working in a very short period of time.Three kinds stop grinding machine
The approach of work: the first is that signal is passed to unit power, and unit power is made to stop working immediately；Second is by signal
Electromagnetic switch 10 is passed to, electromagnetic switch 10 is made to stop the power transmission between power shaft 18 and power gear shaft 26；Such as
Aa and Ab show normal operating conditions in Figure 19, the third is to pass to signal to reset motor 22, keep reset motor 22 de-
From self-locking state, then reseting gear 24 will not play the role of limiting arc balance 15, as shown in the Ba in Figure 19, this
When restoration spring 12 on elastic force F3 will make arc balance 15 to away from restoration spring 12 direction swing, to drive gear 17
It is detached from chuck gear ring 3, as shown in the Bb in Figure 19, reduction gearing 14 is engaged with chuck gear ring 3, then chuck 4 and chuck tooth
The remaining kinetic energy of circle 3 passes to speed cone 31 by reduction gearing 14 and transmission gear 19, and kinetic energy entrained by speed cone 31 is again
