The bindiny mechanism 52 is flexible linking device, and it includes installing plate 521, adapter sleeve 522, the and of connecting shaft 523
Flexible filler 524, the installing plate 521, which is fixedly connected in the bottom of walking mechanism 51, the adapter sleeve 522, to be offered greatly
Under small shoulder hole, the connecting shaft 523 is in up big and down small ladder shaft-like, and the top of the adapter sleeve 522 is fixedly connected on
On the bottom surface of installing plate 521, the connecting shaft 523 is contained in shoulder hole and its bottom extend out to the lower section of adapter sleeve 522,
So that the fixed seat 531 is fixedly connected on the bottom of connecting shaft 523, the flexible filler 524 is connected to connecting shaft 523 and peace
(resetted between dress plate 521 by flexible filler and energy-absorbing).Because walking mechanism positioning can not possibly be with mould installion hole
Position is completely the same, and the equal error such as position error, coaxiality error, the depth of parallelism during motion is can hardly be avoided, so as to cause mould
When tool is installed, mould collides with mounting hole seat, causes burn failure.In this regard, proposing flexible linking device in this case, make
Adapter sleeve therein and connecting shaft have certain amount of can be movable relatively, so that die hole effectively is directed at when mould is put into,
And effective absorption is carried out to the impact force on mould, the purpose being accurately and efficiently put into mould in mould position is realized, and have

Representative explanation is carried out to rotating driving device below by two kinds of embodiments：(when actual use, from production cost
And efficiency of movement angle is set out and generally used from embodiment one)
Embodiment one：The rotating driving device 536 include with the rotary cylinder 5361 of line shaft, little gear 5362,
Gear wheel 5363, limiting cylinder 5364 and limited block 5365 with drive shaft, the rotary cylinder 5361 are fixedly connected on
In reservation 531 and its line shaft is stretched in guide sleeve 532, the little gear 5362 is socketed in the power of rotary cylinder 5361
On axle, the gear wheel 5363 is fixedly connected with the cam disc 533 and is meshed with little gear 5362, the gear wheel 5363
It is concentric with cam disc 533；So, by rotary cylinder can driving pinion, and then by gear wheel drive camshaft rotate,
So as to finally drive clamping jaw to do straight-line displacement；
At the same time, because the rotary cylinder speed of service is fast, but running precision is poor, and transportation load is difficult to control, therefore this reality
Apply also to be additionally arranged in example and spacing mechanism is carried out to the cam disc anglec of rotation, be specifically described as follows：
Offer the stopper slot 5331 of arc on the top surface of the cam disc 533, the center line of the stopper slot 5331 with
The axis coinciding of cam disc 533；
The limiting cylinder 5364 is fixedly connected in fixed seat 531 and its drive shaft is stretched in guide sleeve 532, institute
State the bottom that limited block 5365 is fixedly connected on drive shaft so that limited block 5365 stretched under the drive of limiting cylinder 5364 or
Exit stopper slot 5331.So, when limited block is stretched into the stopper slot on cam disc under the driving of limiting cylinder, you can letter
Single, the effective anglec of rotation to cam disc is controlled.With reference to actual use：When capturing large scale mould, limited block is moved back
Go out stopper slot, stopper slot does not work, the opening between some clamping jaws is maximum, realize the crawl to large scale mould；Work as crawl
, it is necessary to limit the opening degree between some clamping jaws during small size mould, now limited block is stretched into, stopper slot works.
The stopper slot 5331 is multistage stepped in what is successively decreased step by step from top to bottom.So, can be to the amount of stretching into of limited block
It is controlled, so that the anglec of rotation limit amount to cam disc is controlled.
Embodiment two：The rotating driving device includes servomotor, little gear and gear wheel with output shaft, described
Servomotor is fixedly connected in fixed seat and its output shaft is stretched in guide sleeve, and the little gear is socketed in servomotor
Output shaft on, the gear wheel is fixedly connected with the cam disc and is meshed with little gear, and the gear wheel and cam disc are same
Axle center.Because servomotor has the characteristics of running precision is high, price is high, therefore letter is directly sent by control centre when using
Number the anglec of rotation of cam disc can be accurately controlled, i.e., the displacement of clamping jaw accurately be controlled.
If the arbitrfary point on the center line of camshaft is i points, the spacing in the axle center of i points and camshaft is Ri, now cam
The Impact direction of groove is the radial direction of cam disc, and the angle of itself and the normal direction of i points is α i, and C is the reinforcement coefficient of cam disc, is one to consolidate
Definite value；
The center line of the cam path can be made up of some sections of straight lines, and place uses arc transition between adjacent straight line, institute
The center line for stating cam path meets arbitrfary point：Ritan(αi)=C；
The cam path can also be the SPL being fitted by some interpolation points, and any interpolation point meets Ritan
(αi)=C.
By the flexible design of the curve to the cam path in cam disc in this case, following characteristics are made it have：First, clamping jaw
Forming range is big, has reinforcement effect during clamping mould；2nd, it can be effectively ensured relatively permanent to the grasp force of various sizes of mould
It is fixed；3rd, clamping jaw can realize quick operation in non-gripping point motion.Specific demonstration is as shown in figure 31：
Assuming that the driving torque after rotated drive device drive on cam disc is M, and, and camshaft are taken at 1 point at 2 points at 1 point
The spacing in axle center be that R1, now the stress F1 of cam path direction and the angle of 1 point of normal direction are a1；21 points and camshaft
The spacing in axle center is that R2, now the stress F2 of cam path direction and the angle of 1 point of normal direction are a2；
Reinforcement effect：Using 2 points as example,That is reinforcement coefficient is got over hour, and reinforcement effect is better；
Accommodate power constant：Due to R1Tan (a1)=R2Tan (a2), thus it is identical with the blessing power at point 2 in point 1, it is ensured that
When clamping different-diameter mould, power is accommodated constant.
Non-clamping point is quickly moved：When the pressure angle of non-clamping point takes higher value, it is possible to achieve quick mobile, effect is improved
Rate.
