Description

Scissor clamp mechanism
Technical field
The utility model relates to the fixture for automobile making, particularly a kind of scissor clamp mechanism.
Background technology
At present, along with the fast development of automobile industry, more and more higher to the requirement of the relevant fixture quality of manufacture automobile; In actual production process, the most frequently used structure is that top clamp arm can be with the opening and clamping of clamp arm in the flexible realization of cylinder, and bottom is usually used as the fixed part application of assigning to.When running into the upper and lower clamping point of space requirement, all open while dodging workpiece, often adopt two cylinders to move to meet this demand with the opposite direction of principle; Do like this and not only extended the time of operation operation and the difficulty of arrangement space, more can strengthen production cost.
Therefore, provide a kind of simple in structure, reasonable in design, apply easy, the significant scissor clamp mechanism of effect, be one of these those skilled in the art problem that should address.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of simple in structure, reasonable in design, performance safety is reliable, applicability is strong scissor clamp mechanism is provided.
The technical scheme that the utility model adopts is for achieving the above object: a kind of scissor clamp mechanism, is characterized in that this mechanism comprises clamp arm, lower clamp arm, connecting plate, connecting axle, bottom front end positive stop, spacing scotch, top front end positive stop, rear end, top caging bolt, connecting axle catch, rear end, bottom caging bolt, cylinder and supplemental support seat;
The middle part of described upper clamp arm and lower clamp arm is connected with connecting plate by connecting axle, and described cylinder is connected with the afterbody of lower clamp arm with upper clamp arm respectively by connecting axle; Make cylinder, upper clamp arm, lower clamp arm and connecting plate four parts form framework quadric chain; On the connecting axle of these framework four connecting rods, supplemental support seat is installed, connecting axle catch is installed to block connecting axle and to be fixed in supplemental support seat one side; The outside end face mounting limit scotch of supplemental support seat, top front end positive stop is installed on clamp arm lower surface, bottom front end positive stop is installed on the upper surface of lower clamp arm, both are corresponding with one heart up and down, upper clamp arm is provided with rear end, top caging bolt, and supplemental support seat is provided with rear end, bottom caging bolt.
The beneficial effects of the utility model are: scissor clamp mechanism has adopted the operation principle of better simply scissors, can realize upper and lower two-part simultaneously clamping and the action of opening.Solved complicated problem by simple principle, performance safety is reliable, has reduced difficulty of processing simultaneously, has saved production cost; Moreover, the shape of upper and lower clamp arm can design according to actual topology requirement, can form modular design considerations, saves design time, for follow-up processing, manufacture, installation, debugging provide more sufficient time and convenience.This mechanism's intensity is high, not yielding, has both guaranteed the precision of production equipment, has improved again the quality of machine-shaping product.
In a word, it is simple and compact for structure, reasonable in design, easy and simple to handle, practical.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model perspective view;
In figure: clamp arm on 1,2 times clamp arms, 3 connecting plates, 4 connecting axles, 5 bottom front end positive stops, 6 spacing scotch, 7 top front end positive stops, 8 rear end, top caging bolts, 9 connecting axle catch, 10 rear end, bottom caging bolts, 11 cylinders, 12 supplemental support seats.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment providing according to the utility model, structure, feature, details are as follows:
Referring to Fig. 1, Fig. 2, a kind of scissor clamp mechanism, this mechanism comprises clamp arm 1, lower clamp arm 2, connecting plate 3, connecting axle 4, bottom front end positive stop 5, spacing scotch 6, top front end positive stop 7, rear end, top caging bolt 8, connecting axle catch 9, rear end, bottom caging bolt 10, cylinder 11 and supplemental support seat 12.
This scissor clamp mechanism is stretched out and retraction by cylinder rod, take connecting axle 4 as center of rotation, when realizing upper and lower clamp arm 1,2, opens and clamps.11 liang, cylinder is located connecting axle and is connected with the afterbody of lower clamp arm 2 with upper clamp arm 1 respectively, the middle part of upper clamp arm 1 and lower clamp arm 2 is connected with connecting plate 3 by connecting axle 4 again, thereby makes cylinder 11, upper clamp arm 1, lower clamp arm 2 and connecting plate 3 four parts form framework quadric chain.On the connecting axle 4 of these framework four connecting rods, supplemental support seat 12 is installed, connecting axle catch 9 is installed to block connecting axle 4 and to be fixed in supplemental support seat 12 1 sides.The outside end face mounting limit scotch 6 of supplemental support seat 12, the Main Function of spacing scotch 6 is that clamp arm 1 and lower clamp arm 2 are in the stop that puts in place clamping after motion finishes, to prevent excessive clamping.Top front end positive stop 7 is installed on clamp arm 1 lower surface, bottom front end positive stop 5 is installed on the upper surface of lower clamp arm 2, both are corresponding with one heart up and down, top front end positive stop 7, bottom front end positive stop 5 contact with spacing scotch 6 after putting in place for upper and lower clamp arm 1,2 clamps, thereby play the stopping function that puts in place.In addition, upper clamp arm 1 is provided with rear end, top caging bolt 8, and supplemental support seat 12 is provided with rear end, bottom caging bolt 10, and both are the stop component that puts in place in opening procedure as upper and lower clamp arm 1,2 respectively.
Adopt screw connecting axle catch 9 to be fixed on to corresponding connecting axle 4 one sides of supplemental support seat 12 sides.
Described top front end positive stop 7 is the columniform block of irony.
Described bottom front end positive stop 5 is the columniform block of irony.
During application, at upper and lower pressure point, all need to abdicate under the occasion that certain space could meet Production requirement, this structure can reach ideal effect.
Above-mentionedly with reference to embodiment, this scissor clamp mechanism being described in detail, is illustrative rather than determinate, therefore in the variation and the modification that do not depart under the utility model general plotting, within should belonging to protection domain of the present utility model.
