Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figures 1 to 4, a kind of embodiment according to the specific embodiment of the invention is: a kind of disc type flexible holding device, and it comprises fixed disk 1, rotating disk 2, traveller 3, articulated column 4, holding piece 5 and pushing mechanism, wherein:
As shown in Figure 2, the centre of fixed disk 1 is provided with first material hole 11, be provided with several deep-slotted chip breakers 12 to the even circumferential of front end face along the center of circle on the axis of the first material hole 11 of fixed disk 1, the center of circle of deep-slotted chip breaker 12 is also positioned on the axis of the first material hole 11.Be respectively arranged with several torsionsprings 13 in these several deep-slotted chip breakers 12, torsionspring 13 is laterally layed in deep-slotted chip breaker 12, and when torsionspring 13 is under pressure, it can compress along deep-slotted chip breaker 12, and when pressure is eliminated, torsionspring 13 automatically resets.
As shown in Figure 3, the centre of rotating disk 2 is provided with second material hole 21 corresponding with the first material hole 11, and shaft-like crops pass from the first material hole 11 and the second material hole 21.Be provided with three arc-shaped through-holes 22 to the even circumferential of rotating disk 2 along the center of circle on the axis of the second material hole 21, arc-shaped through-hole 22 runs through the face, rear and front end of rotating disk 2.
Rotating disk 2 is rotatably fastened on the front end of fixed disk 1.As shown in Figure 2, the rear end of several travellers 3 is fixedly installed on the middle part of several torsionsprings 13 respectively, and when rotating disk 2 is installed on fixed disk 1, the front end of these several travellers 3 is fixedly installed on the rear end face of rotating disk 2 respectively, when rotating disk 2 rotates, its effect that traveller 3 can be driven to overcome torsionspring 13 is slided along deep-slotted chip breaker 11.Preferably, as shown in Figures 2 and 3, the quantity of deep-slotted chip breaker 12 is three, then the quantity of traveller 3 is also three.As shown in Figure 2, the rear end of three articulated columns 4 is fixedly installed on fixed disk 1, when rotating disk 2 is installed on fixed disk 1, these three articulated columns 4 respectively active card are embedded in three arc-shaped through-holes 23 on rotating disk 2, and these three articulated column 4 front ends are piercing in forward three arc-shaped through-holes 23, because articulated column 4 is flexibly connected with arc-shaped through-hole 23, therefore articulated column 4 can not affect the rotation of rotating disk 2.
As shown in Figure 4, the outer end of holding piece 5 is provided with a round pin 51, and the middle part of holding piece 5 is provided with a hinge hole 52, as shown in Figure 1, the outer end of three holding pieces 5 is rotatably arranged at the circumferentially same of the front end face of rotating disk 2 respectively by round pin 51, and these three holding pieces 5 carry out hinged with the front end of three articulated columns 4 by the hinge hole at middle part respectively, the front end activity of articulated column 4, through hinge hole 52, is then stably limited in holding piece 5 front end of articulated column 4 by fastening cover 54.The inner of three holding pieces 5 is used for common gripping objects, and preferably, as shown in Figure 1 and Figure 4, holding piece 5 is arc surface for the side 53 of gripping objects.Thus make holding piece 5 and shaft-like crops carry out smooth contact, reduce the damage to shaft-like crop surface further.
Pushing mechanism 6 rotates for driving rotating disk 2.As shown in Figure 1, pushing mechanism comprises servomotor 64 and linkage, and servomotor 64 is connected with rotating disk 2 by linkage, rotates to drive rotating disk 2.When servomotor 64 keeps energising, it maintains moment of torsion to main shaft, to be controlled the rotation of rotating disk 2 by linkage, and when servomotor 64 power-off, there is not moment of torsion in its main shaft, main shaft can rotate, thus the rotation of linkage and rotating disk 2 can not produce restriction.Preferably, linkage comprises first connecting rod 61 and second connecting rod 62, one end of first connecting rod 61 and the side of rotating disk 2 hinged, one end of second connecting rod 62 and the other end of first connecting rod 61 hinged, and the other end of second connecting rod 62 is connected by one speed reducer 63 with servomotor 64, whole pushing mechanism is a crank and rocker mechanism.Servomotor 64 and decelerator 63 all can be fixedly installed on fixed disk 1.
Under original state, as shown in Figure 1, the inner of three holding pieces 5 is drawn close together to be in closure state, and articulated column 4 is positioned at arc-shaped through-hole 22 front end along clockwise direction.When needs gripping rods crops, servomotor 64 drives rotating disk 2 to rotate clockwise by first connecting rod 61 and second connecting rod 62, when rotating disk 2 turn to articulated column 4 be positioned at arc-shaped through-hole 22 rear end along clockwise direction time, servomotor 64 receives lock zero-signal to carry out self-locking.In the rotation process of rotating disk 2, rotating disk 2 drives the outer end of holding piece 5 to rotate clockwise by round pin 51, thus holding piece 5 is rotated clockwise around articulated column 4, and the inner of three holding pieces 5 just separates, and the second material hole 21 is opened completely.In addition, in the rotation process of rotating disk 2, the effect that its promotion traveller 3 overcomes torsionspring 13 is slided along deep-slotted chip breaker 12, makes torsionspring 13 produce elastic potential energy.Then the shaft-like crops such as sugarcane or cornstalk just can be fed forward and pass outside the first material hole 11 and the second material hole 21, when needs clamp shaft-like crops, power-off is carried out to servomotor 64, thus the auto-lock function of servomotor 64 is automatically terminated, to unclamp linkage and rotating disk 2, torsionspring 13 recovers under the effect of elastic potential energy, thus drive traveller 3 to drive rotating disk 2 to rotate counterclockwise, rotating disk 2 drives holding piece 5 to rotate counterclockwise around articulated column 4, the inner of three holding pieces 5 is closed to clamp shaft-like crops, the chucking power of three holding pieces 5 is provided by three torsionsprings 13, thus can according to the diameter of shaft-like crops large little come flexible clamping to shaft-like crops.When needs unclamp shaft-like crops, again servomotor 64 is energized, drives holding piece 5 to rotate clockwise to control rotating disk 2.
The present invention controls the clamping dynamics of holding piece 5 to shaft-like crops by torsionspring 13, to realize flexible clamping, it can stably clamp shaft-like crops, effectively can avoid again clipping broken and damage shaft-like crops, thus bring convenience for carrying out the process such as cutting off to shaft-like crops.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
