Abstract
The invention discloses a centering mechanism for a clamping device of a cutting machine. An extension bar of a first oil cylinder is hinged with a first connecting bar. A first clamping shoe is fixedly connected with one end of the first connecting bar through a sliding bar, and the other end of the first connecting bar is hinged with one end of a second connecting bar. The other end of the second connecting bar is hinged with one end of a crank. An extension bar of a second oil cylinder is respectively hinged with one end of a third connecting bar and one end of a fourth connecting bar. A second clamping shoe is fixedly connected with the other end of the third connecting bar through the sliding bar. The other end of the fourth connecting bar is hinged with the other end of the crank. A rotating center of the crank is positioned in the center of the crank. The length of the second connecting bar is equal to the length of the fourth connecting bar. In addition, the second connecting bar and the fourth connecting bar are centrosymmetric relative to the rotating center of the crank. The tail parts of the first oil cylinder and the second oil cylinder are respectively hinged with each fixed point of a machine frame. The mechanism is simple and forcefully ensures two oil cylinders in the same pace through mechanical connection, thereby effectively reducing central deviation due to the external deviation of a workpiece clamping part and improving the centering precision during clamping.
Description
Technical field
The present invention relates to stock-removing machine and clamp centering body, especially relate to a kind of centering body of stock-removing machine clamping device.
Background technology
Existing pair of oil cylinder centering clamping device mainly contains two kinds of modes at present.One, rely on hydraulic system to guarantee that two oil cylinders are synchronous to the fuel delivery of two oil cylinders is consistent, this kind method causes accuracy of alignment to guarantee owing to the interior discharge of oil cylinder there are differences, and the hydraulic system complexity; Two, be to force location, another side to adopt to float on one side to clamp, this mode is higher to the required precision of workpiece gulde edge, has limited to the utilization of this method in cutting clamps.
Summary of the invention
In order to overcome the not high problem of original clamping device accuracy of alignment, the object of the present invention is to provide a kind of centering body of stock-removing machine clamping device.
In order to reach the foregoing invention purpose, the technical solution used in the present invention is:
The extension bar and the first connecting rod of first oil cylinder are hinged, and first folder is watt affixed by an end of slide bar and first connecting rod, and an end of the other end of first connecting rod and second connecting rod is hinged, and an end of the other end of second connecting rod and crank is hinged; The extension bar of second oil cylinder is hinged with an end of third connecting rod and the 4th connecting rod respectively, and second folder is watt affixed by the other end of slide bar and third connecting rod, and the other end of the 4th connecting rod and the other end of crank are hinged; The centre of gyration of crank is positioned at the center of crank; Second connecting rod equates that with the 4th length of connecting rod second connecting rod and the 4th connecting rod are about the centre of gyration center symmetry of crank simultaneously, and the afterbody of first oil cylinder and second oil cylinder is hinged with frame fixing point separately respectively.
The shape of described two folders watt is V font or planar shaped or circular arc according to being held the setting of workpiece shape.
The beneficial effect that the present invention has is:
Entire mechanism of the present invention is simple and easy to realization, and forces to guarantee that by mechanical connection two oil cylinders are synchronous, can effectively reduce because workpiece clamps the misalignment that the deviation of position profile causes the accuracy of alignment when raising clamps.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present invention.
Among the figure: 1, first oil cylinder, 2, second connecting rod, 3, crank, the 4, the 4th connecting rod, 5, second oil cylinder, 6, third connecting rod, 7, second folder watt, 8, workpiece, 9, first folder watt, 10, first connecting rod.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, the extension bar of first oil cylinder 1 and first connecting rod 10 are hinged, and first folder is watt affixed by an end of slide bar and first connecting rod 10, and an end of the other end of first connecting rod 10 and second connecting rod 2 is hinged, and an end of the other end of second connecting rod 2 and crank 3 is hinged; The extension bar of second oil cylinder 5 is hinged with an end of third connecting rod 6 and the 4th connecting rod 4 respectively, and second folder is watt affixed by the other end of slide bar and third connecting rod 6, and the other end of the other end of the 4th connecting rod 4 and crank 3 is hinged; The centre of gyration of crank 3 is positioned at the center of crank 3; Second connecting rod 2 and the 4th connecting rod 4 equal in length, second connecting rod 2 and the 4th connecting rod 4 are about the centre of gyration center symmetry of crank simultaneously, and the afterbody of first oil cylinder 1 and second oil cylinder 5 is hinged with frame fixing point separately respectively.
The shape of described two folders watt is V font or planar shaped or circular arc according to being held the setting of workpiece shape.Two folders are watt can shape identical, also can be different, and look the workpiece profile and can set flexibly.
Its operation principle is:
When work clamps, first oil cylinder 1 and second oil cylinder, 5 move toward one another.First oil cylinder 1 moves, and it is corresponding mobile to drive first connecting rod 10, and 10 of first connecting rods drive second connecting rod 2 and move, and 2 of second connecting rods drive crank 3 and rotate, and crank 3 rotates drive the 4th connecting rod 4 and moves, and the 4th connecting rod 4 drives third connecting rods 6 and second oil cylinder 5 moves.Because second connecting rod 2 and the 4th connecting rod 4 are about crank up revenue centre symmetry, the displacement of the 4th connecting rod 4 equates with the displacement of second connecting rod 2, third connecting rod 6 equates with the displacement of first connecting rod 10, then the displacement of second folder watt and first folder watt equates, thus the centering clamping of realization workpiece 8.The second same oil cylinder 5 moves that also can to drive first oil cylinder, 1 mobile phase equidistant, guarantees workpiece centering clamping accuracy.
With reference to accompanying drawing, provide the foregoing description will help to understand the present invention, but do not limit content of the present invention by embodiment.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
