Background technology
The swing clamping cylinder is the important composition parts of anchor clamps, can arrange in operator's direction of flat push type logistics anchor clamps and compress reliably a little, be used for clamping work pieces, thereby improve the stability of part to be processed in process, it is for guaranteeing that crudy has important effect.But existing swing clamping cylinder is under open mode, peak generally is higher than the workpiece locating surface of anchor clamps, and when clamping cylinder was opened, the logistics that fork or connecting rod are positioned at workpiece went out Inbound, this has brought obstruction just for the flat push type logistics that is used for workpiece loading and unloading, that is to say to stop that logistics flows out smoothly.
The utility model content
Technical problem to be solved in the utility model provides a kind of under open mode, and each parts all can draw in the swing clamping cylinder of the locating surface below of workpiece.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of swing clamping cylinder, comprise cylinder body and piston rod, the upper surface of described cylinder body is provided with projection and first connecting rod, one end of described first connecting rod is hinged on the described projection, one end of the other end of described first connecting rod and a fork is hinged, described fork is provided with the pressure head for clamping work pieces, the other end and the second connecting rod of described fork are hinged, one end of the other end of described second connecting rod and third connecting rod is hinged, and the other end of described third connecting rod and described piston rod are hinged; The end and the described first connecting rod that also are provided with the 4th connecting rod and described the 4th connecting rod between described first connecting rod and the described piston rod are hinged, and the other end of described the 4th connecting rod and described piston rod are hinged.
The beneficial effects of the utility model are: in view of technique scheme, in fact, first connecting rod, fork, second connecting rod, third connecting rod and the 4th connecting rod have formed the swing mechanism of five connecting rods, during clamping, the normal clamping work pieces of pressure head on the fork, when opening, above-mentioned all parts comprise fork, all can draw in below the locating surface of workpiece, can not pass moving by the interferences levelling.
On the basis of technique scheme, the utility model can also be done following improvement:
Further, the pin joint of the pin joint of described third connecting rod and described piston rod and described the 4th connecting rod and described piston rod is same pin joint.The beneficial effect that adopts above-mentioned further scheme is five bar linkage structures of being convenient to form standard, and in addition, same pin joint is connected and fixed also more convenient.
Further, described projection is the fixed bar of a vertical vertically-arranged.The beneficial effect that adopts above-mentioned further scheme is to have realized very easily and being connected of first connecting rod.
Further, described piston rod through extension rod respectively with described third connecting rod, described the 4th rod hinge connection.The beneficial effect that adopts above-mentioned further scheme is convenient the connection.
Description of drawings
Fig. 1 is the schematic diagram of existing swing clamping cylinder;
Fig. 2 is the schematic diagram of two adjacent the utility model swing clamping cylinders;
Fig. 3 is that the utility model swing clamping cylinder is from being clamped to the movement decomposition schematic diagram of opening.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, cylinder body, 2, piston rod, 3, fixed bar, 4, first connecting rod, 5, fork, 5a, pressure head, 6, second connecting rod, 7, third connecting rod, the 8, the 4th connecting rod.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
Fig. 1 is the clamped condition of the swing clamping cylinder of prior art, and when changing to rounding state, piston rod 2 moves downward, and pressure head 5a one side of fork 5 can perk, and the position is still very high, when running into some irregular workpiece, can push to release with workpiece and interferes.Fig. 2 is a kind of swing clamping cylinder structure of the present utility model, for clarity, here will work simultaneously two the swing clamping cylinders that are in different conditions are placed among the same figure and compare, the left side swing clamping cylinder is in clamped condition among Fig. 2, and a swing clamping cylinder on the right is in open mode.For each swing clamping cylinder, comprise cylinder body 1 and piston rod 2, the upper surface of cylinder body 1 is provided with fixed bar 3 and first connecting rod 4, one end of first connecting rod 4 is hinged on the fixed bar 3, here, fixed bar 3 is projections with same height that are positioned at cylinder body 1 upper surface, also is fine.One end of the other end of first connecting rod 4 and a fork 5 is hinged, fork 5 is provided with the pressure head 5a for clamping work pieces, the other end of fork 5 and second connecting rod 6 are hinged, and an end of the other end of second connecting rod 6 and third connecting rod 7 is hinged, and the other end of third connecting rod 7 and piston rod 2 are hinged; Also be provided with the 4th connecting rod 8 between first connecting rod 4 and the piston rod 2, and an end of the 4th connecting rod 8 and first connecting rod 4 are hinged, the other end of the 4th connecting rod 8 and piston rod 2 are hinged.Here the piston rod of mentioning 2 also can be to link to each other and with the piston rod extension rod of piston rod 2 actions with piston rod 2.That is to say, in fact first connecting rod 4, fork 5, second connecting rod 6, third connecting rod 7 and the 4th connecting rod 8 have formed five linkage swing mechanisms, and when being in clamped condition, piston rod 2 is in upper, this moment, first connecting rod was vertical vertically-arranged state, and the pressure head 5a of fork 5 clamps workpiece at this moment; When being in open mode, piston rod 2 moves down, under the effect that forms five-bar mechanism, fork rotates the bottom with pin joint on the one hand, draws in gradually, and first connecting rod 4 is also pulled down by piston rod 2 on the other hand, when being in full open position at last, first connecting rod is in level, and fork and each connecting rod all are in below the workpiece locating surface, and the work locating surface is represented by a horizontal line of the top among Fig. 2.Fig. 3 is the process that gradually changes of the centre from the clamped condition to the open mode in the direction of arrows.
The situation that a last paragragh is described is a preferred embodiment of the present utility model, and each parts of the swing clamping cylinder after also drawing in as can be seen from Fig. 3 all are lower than workpiece locating surface height, have reached the effect that expection is drawn in.Each length of connecting rod; fork length and pin joint position can change within the specific limits; the position of each parts after finally causing drawing in may be slightly different; give an example; the length of second connecting rod 6 is long slightly; the possibility of result causes end-state to draw in fully unlike last state of Fig. 3 so; but can reach the rounding state of Fig. 3 penult; equally also can satisfy instructions for use; so long as this five connecting rods or with its approximate structure; peak is lower than the height of workpiece locating surface when satisfying gathering; the turnover that makes workpiece can not conflict mutually with fork 5 and each connecting rod, and clog-free release or push so just belongs to protection scope of the present invention.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
