Description
Technical field
This utility model relates to clamping device field, particularly relates to a kind of big opening degree formula clamping device.
Background technology
Clamping device typically refers to a kind of by the object clampings such as instrument, workpiece, material or fixing mechanism.
In auto parts machinery production process, accessory is gripped frequently with tool formula clamping device, mechanical type gripping body generally includes grip slipper and paired jaw, jaw is hinged on clamping grip slipper, the drive mechanism of dynamic source or power source is connected on jaw, power source or power source drive mechanism promote jaw to rotate the opening degree changed between jaw, utilize the change gripping accessory of opening degree between paired jaw.Opening degree is the air line distance between jaw gripping point, and opening degree is the biggest, and the overall dimensions of the accessory that can grip is the biggest.Owing to the pin joint of the jaw of conventional clamping device is affixed on grip slipper, hence in so that the opening degree of jaw receives the restriction of grip slipper, it is not easy to grip the accessory that overall dimensions is bigger.
Utility model content
This utility model is intended to provide a kind of big opening degree formula clamping device, makes the opening degree of clamping device not limited by grip slipper, in order to the accessory that gripping overall dimensions is bigger.
Big opening degree formula clamping device in this programme, including grip slipper, the first chute is had on grip slipper, also include connecting rod scaling device, connecting rod scaling device is made up of even number crossed joint, use hinge pin hinged between crossed joint, the midpoint of connecting rod scaling device includes the first hinge pin and the second hinge pin, first hinge pin is fixed in the first chute, second hinge pin is slidably connected in the first chute, second hinge pin connects cylinder, cylinder is fixed on grip slipper, described connecting rod scaling device two ends are connected to a jaw, the second chute is had on jaw, the two ends of connecting rod scaling device all include the 3rd hinge pin and the 4th hinge pin, 3rd hinge pin is hinged on jaw, 4th hinge pin is slidably connected in the second chute.
The know-why of this programme is: uses a hinge pin to connect in the middle of the connecting rod that each two is isometric, forms a crossed joint, uses two hinge pins hinged, form connecting rod scaling device between each two crossed joint, and connecting rod scaling device can stretch in the axial direction；Cylinder promotes the second hinge pin to slide, the distance between the second hinge pin and the first hinge pin is made to diminish, connecting rod scaling device extends, and connecting rod scaling device two ends drive jaw displacement, and the distance between jaw increases, cylinder pulls the second hinge pin to slide, making the distance between the second hinge pin and the first hinge pin become big, connecting rod scaling device shrinks, and the distance between jaw diminishes, by the change of the spacing of jaw, the gripping of accessory can be realized.
This programme have the beneficial effect that 1, jaw separates with grip slipper, the opening degree of jaw is only relevant with the stroke of bar linkage telescopic mechanism, and the opening degree of jaw is not limited by grip slipper；2, simultaneously, this programme only needs the quantity increasing crossed joint just can increase the stroke of bar linkage telescopic mechanism and increase the opening degree of jaw, and prior art is as increased the opening degree of jaw, the length of jaw must be increased, also needing to increase the stroke of the drive mechanism of power source or power source, this programme is more convenient for obtaining bigger opening degree.3, the 4th hinge pin is slidably connected in the second chute, beneficially jaw translation with the flexible of bar linkage telescopic mechanism, to keep the chucking power of jaw, thus ensures the effectiveness of clamping.
Prioritization scheme one based on such scheme: described jaw has breach towards grip slipper side, and the shape of breach coordinates with described grip slipper.In order to be accommodated in breach by grip slipper, and then reduce the distance between jaw, enable jaw to grip the accessory that overall dimensions is less.
Prioritization scheme two based on prioritization scheme one: be fixed with rubber layer inside described jaw.Owing to jaw is usually metal manufacture, during gripping accessory, the face that jaw contacts with accessory may be damaged accessory surface, utilize rubber layer to buffer, it is to avoid jaw damage accessory.
Prioritization scheme three based on prioritization scheme two: described second trough width is equal to described 4th hinge pin diameter.Prevent hinge pin from radial-play occurring in the second chute, and then keep jaw stable, and then ensure the stability of clamping.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment big opening degree formula clamping device.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: grip slipper the 1, first chute 2, connecting rod the 3, first hinge pin the 4, second hinge pin the 5, the 3rd hinge pin the 6, the 4th hinge pin 7, cylinder 8, jaw the 9, second chute 10, breach 11, rubber layer 12.
nullEmbodiment big opening degree formula clamping device is the most as shown in Figure 1: include grip slipper 1，The first chute 2 is had on grip slipper 1，Also include connecting rod scaling device，Connecting rod scaling device is made up of even number crossed joint，Each crossed joint is waited long connecting rods 3 to be hinged secondary in respective midpoint by two，Use hinge pin hinged between two crossed joints，The midpoint of connecting rod scaling device includes the first hinge pin 4 and the second hinge pin 5，First hinge pin 4 is fixed in the first chute 2，Second hinge pin 5 is slidably connected in the first chute 2，Second hinge pin 5 connects cylinder 8，Cylinder 8 is fixed on grip slipper 1，Described connecting rod scaling device two ends are connected to a jaw 9，Jaw 9 has breach 11 towards grip slipper 1 side，The shape of breach 11 matches with described grip slipper 1，Rubber layer 12 it is fixed with accessory on the surface contacted on jaw 9，The second chute 10 is had on jaw 9，The two ends of connecting rod scaling device all include two hinge pins，Two hinge pins are respectively the 3rd hinge pin 6 and the 4th hinge pin 7，3rd hinge pin 6 is hinged on jaw 9，4th hinge pin 7 is slidably connected in the second chute 10.
Cylinder 8 pulls the second hinge pin 5 to slide, the distance between the second hinge pin 5 and the first hinge pin 4 is made to become big, connecting rod scaling device shrinks, and the distance between jaw 9 diminishes, and the rubber layer 12 on jaw 9 surface contacts with accessory, realize the clamping of accessory, and owing to having breach 11 on jaw 9, grip slipper 1 is contained in breach 11, when when being shaped as grip slipper 1 along the half of the separate outline of axis of breach 11, the rubber layer 12 of two jaws 9 offsets, and can clamp the overall dimensions accessory less than 1mm；On the contrary, cylinder 8 promotes the second hinge pin 5 to slide, making the distance between the second hinge pin 5 and the first hinge pin 4 diminish, connecting rod scaling device extends, and connecting rod scaling device two ends drive jaw 9 displacement, and the distance between jaw 9 increases, and jaw 9 decontrols the accessory of clamping.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
