The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1 to Figure 3, a kind of electric clamp comprises a clamp frame 100 and a clamp switching mechanism 200, and clamp switching mechanism 200 is used for controlling the opening and closing of clamp.
Respectively be provided with two pincers legs 300 in these electric clamp both sides, two that are arranged on homonymy are clamped legs against each other.These two pincers leg 300 tops are provided with pincers leg switching mechanism 400, link to each other with this clamp switching mechanism 200 by connecting panel.
Respectively this pincers leg switching mechanism 400 comprises a pushing mechanism 410 and a four-bar linkage that is attached thereto 420.
Wherein, shown in Fig. 3,4, this four-bar linkage 420 comprises: two first connecting rods 421, articulate mutually in the top, and it is continuous to be in this pushing mechanism 410 in this pivot joint; Two second connecting rods 422, its upper end articulates with the lower end of described first connecting rod 421 respectively, and the lower end connects described pincers leg 300 captive joints respectively.
In the present embodiment, described pushing mechanism 410 comprises: an electrical motor 411; A screw rod 412 utilizes a coupler 413 to link to each other with the output shaft of this electrical motor; A nut 414 is set on this screw rod, and links to each other with the articulated section of described first connecting rod 421.
This first connecting rod 421 can be these two first connecting rods, 421 difference or common and these nut 414 pivot joints with the connection mode of nut 414, or the pivot of these two first connecting rod 421 articulated sections is captiveed joint with this nut 414.First connecting rod also can adopt other known connection modes of this area, as long as can be rotated relative to nut.
Under pincers leg 300 closure states, electrical motor 411 rotations drive screw rod 412 and rotate in the same way, then, nut 414 moves downward on screw rod, driving first connecting rod 421 rotates relative to nut 414, and then second connecting rod 422 is rotated relative to first connecting rod 421, pincers leg 300 rotates under the drive of second connecting rod 422, finishes the process of opening from being closed into.In like manner, under pincers leg 300 open modes, turning to of electrical motor 411 is opposite with opening procedure, then, nut 414 upward movements, the transmission of this four-bar linkage of process makes pincers leg 300 closures.
For preventing to clamp leg switching mechanism 400 motor overload in the opening and closing process; the coupler 413 that is provided with between electrical motor and screw rod is designed to moment restraint-type coupler; when the pincers leg open, when meeting obstructions in the closing course; moment restraint-type coupler skids and makes electrical motor idle running, and the protection electrical motor does not burn because of overload.
For maximum, the minimum limit position of restriction pincers leg 300 in closing course, photoelectric switch 301 and mechanical limit switch 302 are housed on clamp.For preventing coil of strip both sides crimping in the clamp gripping coil of strip process, be provided with limit switch at the pincers inboard leg, with electrical motor 411 interlockings of pincers leg switching mechanism, when pincers inboard leg and coil of strip edge contact, pincers leg switching mechanism 400 motors cut off the power supply at once, avoid the coil of strip crimping quality problems to occur.At secure context, for avoiding driver's maloperation occurring in the clamp handling coil of strip process, the pincers leg is aloft opened, make that coil of strip is born to cause the accident, in pincers leg bottom and coil of strip endoporus contact site limit switch or photoelectric sensor switch are set, when switch motion, how to operate clamp pincers leg and can not open, avoid maloperation to cause engine breakdown and personnel casualty accidents.
In the utility model, described pushing mechanism also is an electric pushrod, and wherein, push rod links to each other with the articulated section of described first connecting rod, and first connecting rod can rotate relative to push rod.When push rod is descending, pincers leg 300 is opened, when push rod is up, made pincers leg 300 closures.
