Abstract
The utility model describes a kind of link-type self-locking mechanism, comprises cylinder, fulcrum block, connecting rod and rocking arm, and cylinder and fulcrum block are all positioned at the below of connecting rod, and rocking arm is positioned at the top of fulcrum block simultaneously; Wherein, connecting rod comprises first connecting rod and second connecting rod, and this first connecting rod is by cylinder connector and cylinders; Fulcrum block is connected with first connecting rod; And first connecting rod is connected with rocking arm by second connecting rod; Rocking arm is provided with limited block, pad and contiguous block.Owing to have employed above-mentioned technology, the utility model promotes connecting rod by the action that ejects of cylinder, then drives rocking arm to carry out workpiece pressing by connecting rod, thus avoids the problem that thrust in existing mechanism is little and open angle is little; Meanwhile, utilize stuck state during transmission mechanism conllinear in mechanism to realize auto-lock function, and finally reach and enhance productivity, alleviate operating personnel's burden, ensure the car body panel beating object such as indeformable in welding process.
Description
Technical field
The utility model relates to the field that is welded of body of a motor car, particularly relates to a kind of link-type self-locking mechanism.
Background technology
Along with automobile people life in day by day universal, the welding and assembling technics of body of a motor car have also been obtained development at full speed, so also more and more higher to the requirement of soldering cramping apparatus.
Wherein, in automobile body-in-white welding technique, when artificial upper part, just to consider the operation height of fixture, if fixture pressure head is opened too high, the impact that can bring inconvenience on artificial upper part.
But existing mechanism is difficult to the opening action realizing wide-angle, the thrust simultaneously provided is also sufficient not.
Utility model content
The problem that above-mentioned open angle is little in order to solve, chucking power is little, the utility model provides a kind of link-type self-locking mechanism, can realize the open angle of 172 °, has possessed the chucking power of 360KG simultaneously.
Above-mentioned a kind of link-type self-locking mechanism, comprise cylinder, fulcrum block, connecting rod and rocking arm, described cylinder and fulcrum block are all positioned at the below of connecting rod, and described rocking arm is positioned at the top of fulcrum block;
Wherein, described connecting rod comprises first connecting rod and second connecting rod, and described first connecting rod is by cylinder connector and cylinders; Described fulcrum block is connected with first connecting rod; Described first connecting rod is connected with rocking arm by second connecting rod; Described rocking arm is provided with limited block, pad and contiguous block.
In said mechanism, described cylinder connector is y-type structure.
In said mechanism, described limited block, pad and contiguous block are all positioned at the upper surface of rocking arm.
In said mechanism, described limited block is connected with contiguous block by pad.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of link-type self-locking mechanism, connecting rod is promoted by the action that ejects of cylinder, drive rocking arm to carry out workpiece pressing by connecting rod again, thus avoid the problem that thrust in existing mechanism is little and open angle is little; Meanwhile, utilize stuck state during transmission mechanism conllinear in mechanism to realize auto-lock function, and finally reach and enhance productivity, alleviate operating personnel's burden, ensure the car body panel beating object such as indeformable in welding process.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of link-type self-locking mechanism in the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Fig. 1 is the structural representation of link-type self-locking mechanism in the utility model; As shown in Figure 1, the utility model describes a kind of link-type self-locking mechanism, comprises cylinder 1, fulcrum block 2, connecting rod and Rocker arm 5, and cylinder 1 wherein and fulcrum block 2 are all positioned at the below of connecting rod, and Rocker arm 5 is positioned at the top of fulcrum block 2;
Further, above-mentioned connecting rod comprises first connecting rod 3 and second connecting rod 4, and this first connecting rod 3 is connected with cylinder 1 by cylinder connector 11;
Preferably, in order to better realize transmission effect, above-mentioned cylinder connector 11 have employed y-type structure.
Meanwhile, fulcrum block 2 is connected with first connecting rod 3; And first connecting rod 3 is also connected with Rocker arm 5 by second connecting rod 4; So just define and cylinder 1 is connected to Rocker arm 5 by first connecting rod 3 and second connecting rod 4, thus achieve by the motion of cylinder 1 to the link gear driving Rocker arm 5 to move.
In addition, Rocker arm 5 is also provided with limited block 6, pad 7 and contiguous block 8; Preferred this limited block 6, pad 7 and contiguous block 8 are all positioned at the upper surface of Rocker arm 5, and limited block 6 is connected with contiguous block 8 by pad 7.
In the utility model, the operation principle of link-type self-locking mechanism is: first move through cylinder connector 11 to promote first connecting rod 3 and second connecting rod 4 by ejecting of cylinder 1, then drive Rocker arm 5 to carry out workpiece pressing by first connecting rod 3 and second connecting rod 4.In addition, when above-mentioned transmission mechanism reaches conllinear, mechanism can arrive dead point, so just achieves the state of self-locking, and needs cylinder 1 to provide enough pulling force when unlocking.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
