Sample, center line of the pivoted arm 405 along local width direction are overlapped with the perpendicular bisector between 407 two-end-point of notch, entire 401 edge of driver plate
Perpendicular bisector is symmetrical arranged, so that the movement of sheave driving structure is more steady reliable, is further reduced the movement of sheave driving structure
The vibration generated in the process and noise.Certainly when it is implemented, 405 need of the pivoted arm are connected on notch 407,
Belong to the enforceable range of this sheave driving structure.
Optionally, the length of the pivoted arm 405 of the present embodiment is consistent with 310 length of radial slot.In this way, axis can be made
Pin 402 is contacted with slot bottom, so that 305 rotation process of sheave is more steady, while can preferably reduce entire sheave driving knot
Structure the space occupied.Certainly when it is implemented, the length of the pivoted arm 405 is smaller than the length of radial slot 310, this is also belonged to
The enforceable range of sheave driving structure.
In the outer peripheral sidewall of sheave 305 in the present embodiment annular be uniformly arranged there are four with outer convex Locking arc 404 cooperate
The concave arc slot 308 of setting；90 degree of angles are formed between every two adjacent radial slots 310.I.e. when sheave 305 rotates
After 90 °, pivot pin 402 produces the radial slot 310 on sheave 305.Certainly, the periphery of the sheave 305 of the present embodiment also it is settable its
The concave arc slot 308 of its quantity is only with four concave arc slots 308 in conjunction with attached drawing in this regard, this embodiment is not repeated
Example.
The specific implementation principle of the rotary drive mechanism of the present embodiment is as follows: driver plate 401 drives in external driving structure
Lower rotation, when the pivot pin 402 on driver plate 401 does not enter the radial slot 310 of sheave 305, the concave arc slot 308 of sheave 305
It is blocked by the outer convex Locking arc 404 of driver plate 401, sheave 305 remain stationary motionless.When pivot pin 402 has just enter into the radial direction of sheave 305
Slot 310 when, the concave arc slot 308 of sheave 305 is released, hereafter sheave 305 by pivot pin 402 driving and rotate, in turn
The second platform 302 is driven to rotate；With the rotation of sheave 305, when pivot pin 402 leaves above-mentioned radial slot 310, sheave 305
Concave arc slot 308 be stuck again, sheave 305 restores stationary state, until pivot pin 402 enters back into sheave 305
Another radial slot 310, sheave 305 turn over 90 ° every time.
It please refers to shown in Fig. 6, lift drive mechanism, the first platform 203 for driving feeding clip mechanism to go up and down is longitudinally
Rise and decline, including the elevating lever 501 being connected with the lower end surface of the first platform 203, and be connected with elevating lever 501 suitable for drive
The lifting driving assembly that dynamic elevating lever 501 is gone up and down along a pair of of 301 direction of guide rod.
The lifting driving assembly of the present embodiment include be vertically connected with the bottom of elevating lever 501 ship and resell on another market 502, with it is second flat
The columned engaging column 505 being connected at the top of the support column 503 of 302 upper surface of platform being rotatedly connected and support column 503, and
It is fixedly sheathed in the transmission gear 507 at 503 middle part of support column.

After 205 expansion force of spring clamps workpiece, the first platform 203 rises under the action of elevating lever 501 along guide rod 301, rises
Rotary drive mechanism acts after to extreme higher position, the second platform of driving 302 and then the rotation for driving feeding clip mechanism, at this point, sheave
305 concave arc slot 308 is blocked by the outer convex Locking arc 404 of driver plate 401, and sheave 305 is stationary, lift drive mechanism band
Dynamic feeding clip mechanism drops to minimum point, and under the action of cam 208, a pair of of opening of chela 101 puts down workpiece, thereafter feeding clip mechanism
Highest point is risen to further through the effect of lift drive mechanism, the concave arc slot 308 of sheave 305 is released at this time, sheave 305
It is rotated by 90 °, clamps workpiece after feeding clip mechanism decline, repeat above-mentioned action process later, punching press feeding mechanical hand has rotated a circle
At put twice part and grip movement.
