The mechanical arm used for workpiece clamping comprises a connection rod, a supporting component and two clamping jaws which are matched with each other. The tail end of the supporting component is fixedly provided with a telescopic power piece. The front end of the supporting component is fixedly provided with a clamping jaw seat. The two clamping jaws are hinged on the clamping jaw seat symmetrically. The tail end of the connection rod is fixedly connected with a piston rod of the telescopic power piece. The tail portions of the two clamping jaws are intersected, and the tail portions of the clamping jaws are both provided with a chute. A pin shaft is inserted in the clamping jaw seat, and the pin shaft is inserted in the two chutes. The pin shaft is connected with the front end of the connection rod. A pin shaft guide mechanism is arranged on the clamping jaw seat. The mechanical arm used for workpiece clamping has the advantages of being wide in clamping range, strong in clamping force, not prone to enabling clamped things to get loose, and capable of changing different clamping jaws.
Description
Technical field
The utility model relates to a kind of manipulator for workpiece holding, belongs to the manipulator field.
Background technology
At present, the manipulator of prior art, for structural simple, usually directly directly realized by pneumatic or hydraulic claw, perhaps mix the executive components such as sucker, electromagnet at executing agency's end, the manipulator clamping thing of this structure can not be too large, the scope of application is limited, and clamping force is not strong yet, and improves head it off iff the power from cylinder, then technical costs can be multiplied, and still has the low problem of reliability.Simultaneously, can't make adaptation as the pneumatic or hydraulic claw of driving mechanism to profile or the change in size of hot forging workpiece, when workpiece profile or change in size, can only change driving mechanism, increase complexity and the cost of the field.
When the manipulator of this structure is worked, can be competent at respectively the carrying demand of corresponding types workpiece under normal temperature environment; But when the workpiece hot forging high temperature workpiece of required carrying and working environment were high dust state, the mechanical paw of prior art just can the very fast inefficacy because of the impact that is subject to high temperature and dust.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of gripping scope large, and clamping force is strong, is not easy that gripping object is got loose and can changes the manipulator that is used for workpiece holding of different jaws.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of manipulator for workpiece holding, comprise connecting rod, supporting component and two jaws that cooperatively interact, the tail end of supporting component is fixed with flexible force piece, the front end of supporting component is fixed with the jaw seat, two jaws become symmetry shape to be hinged on the jaw seat, the tail end of connecting rod is fixedly connected with the piston rod of flexible force piece, the afterbody of described two jaws becomes cross-like, and the afterbody of jaw all has chute, be fitted with bearing pin on the jaw seat, and this bearing pin is inserted in two chutes, and bearing pin is connected with the front end of connecting rod, is provided with the bearing pin guiding mechanism on the jaw seat.
Further, be provided with the arm cylinder on the described supporting component, described connecting rod passes the arm cylinder.
Further, described bearing pin guiding mechanism comprises gathering sill pressing plate and the guide runner of driving the gathering sill in jaw seat and gathering sill pressing plate and can sliding in gathering sill, and guide runner is sleeved on the bearing pin.
Further, described flexible force piece is increased stroke-adjustable gas cylinder.
After having adopted technique scheme, flexible force piece so that connecting rod travel forward, two jaws open or closure under the cooperation of chute and bearing pin drives, the stretching degree of two jaws depends on the length of chute, chute is longer, the stretching degree of two jaws is larger, like this so that the utility model can the larger gripping object of gripping, and two jaws use bearing pin to connect, be convenient to change the jaw of different model, so that the utility model scope of application becomes large, clamping force is strong, be not easy to make gripping object to get loose, in addition because flexible force piece links to each other with jaw by connecting rod, make its can be fully away from the high temperature forging part or have the gripping object that endangers personal safety, thereby guarantee its service life, also guaranteed its security; The setting of increased stroke-adjustable gas cylinder also can be so that the utility model changes the opening angle of jaw by changing flexible force piece stroke, thereby is easy to adapt to the variation of gripping object outside dimension; The arm cylinder can shield dust or other environmental contaminants of workplace, thereby strengthens service life of the present utility model and reliability.
