It is understood that the driving member 42 in this embodiment is an air cylinder, and of course, in other alternative embodiments, the driving member 42 may be other linear driving structures such as an electric push rod, which is not particularly limited in this embodiment. When the driving member 42 is an electric push rod, the electric motor of the electric push rod can control the stroke of the push rod of the electric push rod, so as to control the rotation angle of the second clamp 12, that is, the electric push rod can control the opening degree of the clamping jaw 1, so as to be suitable for clamping workpieces with different sizes.

In the present embodiment, the return spring 43 is preferably a compression spring, when the pressing plate 41 presses against the second clamp 12 and rotates the second clamp 12 around the first rotating shaft 3, the compression spring is compressed, and when the pressing plate 41 rotates around the fourth rotating shaft 46 and moves toward the side far from the second clamp 12, the compression spring is restored to deform so that the end of the second clamp 12 close to the pressing plate 41 moves toward the side far from the first clamp 11.

Preferably, the distance between the fourth rotating shaft 46 and the first rotating shaft 3 along the moving direction of the movable end 422 of the driving element 42 is adjustable in this embodiment, that is, the distance between the pressing plate 41 and the second clamp 12 along the moving direction of the movable end 422 of the driving element 42 when the pressing plate 41 is not pressing against the second clamp 12 is adjustable, and this embodiment can adjust the maximum angle that the pressing plate 41 controls the second clamp 12 to rotate around the first rotating shaft 3 by adjusting the distance between the pressing plate 41 and the second clamp 12 along the moving direction of the movable end 422 of the driving element 42 when the pressing plate 41 is not pressing against the second clamp 12, so as to control the maximum opening degree of the clamping jaw 1, so as to be suitable for clamping workpieces with different sizes. Specifically, when the distance between the pressing plate 41 and the second clamp 12 along the moving direction of the movable end 422 of the driving member 42 when the pressing plate 41 is not pressing against the second clamp 12 is increased, the length of the extension of the movable end 422 of the driving member 42 required by the pressing plate 41 to press against the second clamp 12 is increased, and since the maximum extension length of the movable end 422 of the driving member 42 is fixed, when the length of the extension of the movable end 422 of the driving member 42 required by the pressing plate 41 to press against the second clamp 12 is increased, the angle at which the pressing plate 41 can control the second clamp 12 to rotate is decreased, that is, the maximum opening degree of the clamping jaw 1 is decreased, accordingly, when the distance between the pressing plate 41 and the second clamp 12 along the moving direction of the movable end 422 of the driving member 42 is decreased when the pressing plate 41 is not pressing against the second clamp 12, the length of the extension of the movable end 422 of the driving member 42 required by the pressing plate 41 to press against the second clamp 12 is decreased, the angle at which the pressing plate 41 can control the second clamp 12 to rotate is increased, i.e. the maximum opening degree of the jaws 1 is increased.

In this embodiment, the mounting plate 2 is connected to the second connecting plate 23, the mounting plate 2 and the second connecting plate 23 are respectively provided with a first connecting hole (not shown) and a second connecting hole 231, the mounting plate 2 and the second connecting plate 23 are connected by a connecting member (not shown) passing through the first connecting hole and the second connecting hole 231, wherein, the mounting plate 2 is provided with more than two first connecting holes which are arranged at intervals along the moving direction of the movable end 422 of the driving member 42, the second connecting holes 231 on the second connecting plate 23 are alternatively aligned with the more than two first connecting holes to adjust the connecting position of the mounting plate 2 and the second connecting plate 23, when the second connecting holes 231 of the second connecting plate 23 are aligned with different first connecting holes, the distance between the fourth rotating shaft 46 and the first rotating shaft 3 along the moving direction of the movable end 422 of the driving member 42 is different.

Of course, in other alternative embodiments, more than two second connection holes 231 may be disposed on the second connection plate 23, and the more than two second connection holes 231 are disposed at intervals along the moving direction of the movable end 422 of the driving element 42, and accordingly, only one first connection hole is disposed on the mounting plate 2, and the first connection hole on the mounting plate 2 is alternatively aligned with the more than two second connection holes 231, so as to adjust the distance between the fourth rotating shaft 46 and the first rotating shaft 3 along the moving direction of the movable end 422 of the driving element 42, which is not particularly limited in this embodiment.

When the movable end 422 of the driving element 42 extends and retracts and the pressing plate 41 is controlled to rotate around the fourth rotating shaft 46, the pressing plate 41 and the movable end 422 of the driving element 42 rotate relatively around the third rotating shaft, and accordingly, the body 421 of the driving element 42 also rotates around the second rotating shaft 44, in order to avoid interference with the rotation of the body 421 of the driving element 42, two supporting plates 21 are arranged on the mounting plate 2 at intervals along the extending direction of the first rotating shaft 3 in the embodiment, the body 421 of the driving element 42 is fixedly connected to the first connecting plate 22, the first connecting plate 22 is rotatably connected between the two supporting plates 21 through the second rotating shaft 44, and a distance is formed between the first connecting plate 22 and the mounting plate 2.

Further, the pressing plate 41 in this embodiment is a steel plate, and the second clamp 12 is made of a polyurethane material, so as to avoid generating scraps due to abrasion of the pressing plate 41 and/or the second clamp 12 during the process that the pressing plate 41 presses against the second clamp 12 and the second clamp 12 rotates around the first rotating shaft 3, thereby ensuring that the working environment of the clamping device has high cleanliness.

Example two

Compared with the first embodiment, the difference of the present embodiment is: in the present embodiment, the distance between the position where the pressing plate 41 abuts against the second clamp 12 and the first rotating shaft 3 is adjustable, that is, in the present embodiment, the maximum angle that the pressing plate 41 controls the second clamp 12 to rotate around the first rotating shaft 3 can be adjusted by adjusting the distance between the position where the pressing plate 41 abuts against the second clamp 12 and the first rotating shaft 3, so as to control the maximum opening degree of the clamping jaw 1, specifically, in the present embodiment, the distance between the position where the pressing plate 41 abuts against the second clamp 12 and the first rotating shaft 3 can be adjusted by replacing the pressing plate 41, but compared with the first embodiment, in the present embodiment, a plurality of standby pressing plates 41 need to be provided, which increases the manufacturing cost, and simultaneously, compared with the first embodiment, the maximum opening degree of the clamping jaw 1 is controlled by adjusting the connection position of the mounting plate 2 and the second connecting plate 23, the manner of replacing the pressing plate 41 in the present embodiment is tedious.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
