Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of forging manipulator binding clip clamp mechanism, structure as shown in Figure 1, the oil cylinder of this clamp mechanism is floating type design, can regulate voluntarily mobile terminal according to the size of power, one clamps two pairs of tong arms of action and can carry out step by step, can reduce impact, and energy automatic capturing, being applicable to clamping cross section is rectangular workpiece.
Fig. 2 and Fig. 3 are orthogonal cutaway view, forging manipulator binding clip clamp mechanism comprises hollow shaft 10, be positioned at tong arm, power section in hollow shaft 10, pull clamping part and promote clamping part, power section is clamping cylinder 9, tong arm comprises first pair of tong arm 1 and second pair of tong arm 2, two pairs of tong arms are about hollow shaft 10 vertical distribution in the axial direction, as shown in Figure 2, pull clamping part to comprise extending type pincers yoke 3, transmitting portions 1, bearing 1 and locking nut 1, locking nut 1 is fixed on one end of extending type pincers yoke 3, plays the effect of locking positioning.As shown in Figure 3, promote clamping part and comprise driving pincers yoke 4, transmitting portions 26, bearing 2 18 and locking nut 28, locking nut 28 is fixed on one end of driving pincers yoke 4, plays the effect of locking positioning.The two ends of clamping cylinder 9 are connected with respectively transmitting portions 1 and transmitting portions 26, transmitting portions 1 is connected with extending type pincers yoke 3 by bearing 1, extending type pincers yoke 3 and first pair of tong arm 1 are hinged, transmitting portions 26 is connected with driving pincers yoke 4 by bearing 2 18, and driving pincers yoke 4 and second pair of tong arm 2 are hinged.
In the present embodiment, bearing 1 and bearing 2 18 are taper roll bearing.
As shown in Figure 4, Figure 5 and Figure 6, clamping cylinder 9 comprises four oil cylinders, two adjacent oil cylinders are one group, rod chamber 13 between every group oil cylinder is connected respectively by oil pipe 16 with rodless cavity 11, the two ends of every group oil cylinder are bound up by installing plate 12 respectively, installing plate 12 is semicircle shape, and two installing plate 12 middle parts can enclose circular hole, convenient installation.
Installing plate 12 is secured by bolts in transmitting portions 1 and transmitting portions 26, because transmitting portions 1 and transmitting portions 26 can clamp yoke 3 and driving pincers yoke 4 moves by extending type, so oil cylinder two ends are floating type installation, oil cylinder both can promote transmitting portions 26 to left movement, also can promote transmitting portions 1 and move right.
Operation principle is as follows:
Because oil cylinder is float design, so extending type pincers yoke 3 and driving pincers yoke 4 all can move when oil cylinder extends, when after a pair of tong arm clamping work pieces wherein, a pair of tong arm also can continue to clamp action in addition, this depends on that extending type pincers yoke 3 and driving pincers yoke 4 are subject to the size of resistance, and the size of resistance depends on the active force of workpiece to jaw.
1, in the time that second pair of tong arm 2 is first clamped to workpiece, it is large that the jaw of second pair of tong arm 2 correspondence is subject to the power that the power of workpiece is subject to workpiece compared with the jaw of first pair of tong arm 1 correspondence, the cylinder piston rod 14 being connected with driving pincers yoke 4 can be considered as to fixed pivot, in this case, cylinder barrel stretches out to the right, promote transmitting portions 1 to the right, transmitting portions 1 is connected with extending type pincers yoke 3 by bearing 1, the power that clamping cylinder 9 acts in transmitting portions 1 like this will be delivered on extending type pincers yoke 3 by bearing 1 and locking nut 1, extending type pincers yoke 3 will be pulled to the right by oil cylinder, extending type pincers yoke 3 and first pair of tong arm 1 are hinged, first pair of tong arm 1 can make horizontal balance be converted to spinning movement with the special transmission form of extending type pincers yoke 3, such first pair of tong arm 1 will be made and clamp action, after having worked, by bearing 1, first pair of tong arm 1 can automatically reset.
2, in the time that first pair of tong arm 1 is first clamped to workpiece, it is large that the jaw of first pair of tong arm 1 correspondence is subject to the power that the power of workpiece is subject to workpiece compared with the jaw of second pair of tong arm 2 correspondence, the cylinder tube 15 being connected with extending type pincers yoke 3 can be considered as to fixed pivot, in this case, cylinder piston rod 14 stretches out left, promote transmitting portions 26 left, transmitting portions 26 is connected with driving pincers yoke 4 by bearing 2 18, the power that clamping cylinder 9 acts in transmitting portions 26 like this will be delivered on driving pincers yoke 4 by bearing 2 18 and locking nut 28, driving pincers yoke 4 will be promoted left by oil cylinder, driving pincers yoke 4 and second pair of tong arm 2 are hinged, second pair of tong arm 2 can make horizontal balance be converted to spinning movement with the special transmission form of driving pincers yoke 4, such second pair of tong arm 2 will be made and clamp action, after having worked, by bearing 2 18, second pair of tong arm 2 can automatically reset.
As shown in Figure 6, in the time clamping action, rodless cavity 11 oil-feeds, because every group oil cylinder hydraulic fluid port communicates, can make the piston rod 14 of oil cylinder synchronously protruding; Because the installing plate 12 at two ends is float design, the installing plate 12 that can promote like this both sides in the time that oil cylinder extends moves, extending type pincers yoke 3 and driving pincers yoke 4 are synchronized with the movement, pull respectively and promote two pairs of tong arms and clamp action, in the time that wherein a pair of tong arm first clamps material, another also can continue to clamp action to tong arm, can regulate voluntarily mobile terminal according to the size of power like this, a clamping action can be carried out step by step, can reduce impact.Between oil cylinder, hydraulic fluid port communicates, and can realize action synchronous, and has increased the power output of oil cylinder.
It is rectangular workpiece that four jaw designs of the utility model uniqueness can clamp cross section, and carries out spinning movement, can automatic capturing, more accurately holding workpiece.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
