First, a centering clamping mechanism according to an embodiment of the present utility model will be described with reference to fig. 1 to 5, and is used for clamping a workpiece, and its application scenario is wide.

As shown in fig. 1 to 5, the centering and clamping mechanism according to the embodiment of the present utility model is used for clamping a workpiece, and includes: a pair of clamping modules 1 and a drive module 2.

Specifically, as shown in fig. 1 to 5, in this embodiment, a pair of clamping modules 1 are disposed opposite to each other, and the clamping modules 1 clamp a workpiece in a centered manner; the driving module 2 is connected with the pair of clamping modules 1 and drives the pair of clamping modules 1 to fold or separate, and the structure is simple and the use is convenient.

Further, as shown in fig. 1 to 5, in the present embodiment, the clamping module 1 includes: the rotating rod 11, the rotating rod 11 is hinged with the driving module 2; the clamping assembly is vertically connected with one end of the rotating rod 11; the driving module 2 drives the rotating rod 11 to rotate around the driving module 2 so as to drive the clamping assembly to move in a centering way, and when the driving module 2 pulls downwards, the rotating rod 11 is driven to rotate around the point where the rotating rod 11 is connected with the driving module 2 so as to drive the clamping assembly to move towards the middle, so that the workpiece is clamped, and when the driving module 2 pushes upwards, otherwise, the clamping assembly moves outwards from the middle, so that the workpiece is discharged.

Further, as shown in fig. 3, in this embodiment, the rotating rod 11 is provided with a kidney-shaped hole 111, the rotating rod 11 is hinged to the driving module 2 through the kidney-shaped hole 111, and the driving module 2 can be connected at different positions of the kidney-shaped hole 111 to adjust the distance between the clamping assembly and the driving module 2, so as to adapt to workpieces with different sizes.

Further, as shown in fig. 1, 3, 4, the clamping assembly comprises: a connecting rod 12, wherein one end of the connecting rod 12 is vertically connected with the rotating rod 11; the centering clamping seat 13 penetrates through the connecting rod 12 and is fixed on the connecting rod 12, so that the clamping of a large block-shaped workpiece is realized, and the centering clamping seat 13 is more stable; the clamping block 14, the clamping block 14 sets up the other end at connecting rod 12, and the clamping block 14 realizes the clamp to small-size work piece, is equipped with the clamp nail 15 on the clamping block 14, but the hole of adaptation foraminiferous work piece realizes the clamp to foraminiferous work piece.

Further, as shown in fig. 1 to 2, the driving module 2 includes: a base 21; the driving piece 22, the driving piece 22 is a hydraulic linear cylinder, and the driving piece 22 is arranged on the base 21; and the pull rod is fixed at the driving end of the driving piece 22, the top of the pull rod 23 is provided with a groove 231, the rotating rod 11 is placed in the groove 231, the stable hinging of the rotating rod 11 and the pull rod 23 is realized, and the driving piece 22 moves up and down through driving the pull rod 23, so that the rotating rod 11 rotates anticlockwise or clockwise.

When the clamping device is used, a workpiece to be clamped is placed between the pair of connecting rods 12, when the hydraulic linear cylinder pulls the pull rod 23 downwards, the pair of rotating rods 11 are driven to rotate around clockwise and anticlockwise directions respectively, so that the pair of centering clamping seats 13, the clamping blocks 14 and the clamping nails 15 are driven to move and fold in a centering manner, the clamping of the workpiece is realized, when the workpiece is taken and placed, the hydraulic linear cylinder pushes the pull rod 23 upwards, the pair of rotating rods 11 are driven to rotate around anticlockwise and clockwise directions respectively, and accordingly the pair of centering clamping seats 13, the clamping blocks 14 and the two sides of the clamping nails 15 are driven to move and separate, and the workpiece is taken and placed.
