[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The pneumatic multifunctional clamp is composed of a clamp body, a positioning component and a power component.

[0025] The clamp body is composed of a pair of opening and closing arms 2 and a plurality of clamps. The opening and closing arms 2 are connected to form a V shape through a rotating shaft at the end, and the opening and closing arms 2 on one side are bent inwards, and the bending angle is an obtuse angle. The clamp body is connected to the top surface of the driving block 9 through the rotating shaft.

[0026] The bending part of the opening and closing arm 2 on one side, including the inner side surfaces on both sides of the bending part, are thinned along the thickness direction, and the processed part is a missing part; two first clamps 4 are symmetrically placed at the missing parts on both sides of the bending part, and are respectively screwed to the opening and closing arm 2 through screws. Corresponding to the first clamp 4, the inner side surface of the opening and closing arm 2 on the other side is also provided with a missing part, and the second clamp 5 is screwed to the missing part. That is, the first clamp 4 and the second clamp 5 arranged at the missing parts on both sides constitute a clamping part.

[0027] Taking the rotation axis of the clamp body as the base point, the opening and closing arms 2 on both sides are respectively provided with a plurality of pin holes 3 along the longitudinal direction, and the pin holes 3 are symmetrical to each other based on the center line of the clamp body.

[0028] The positioning assembly is composed of a pair of steering arms 6, a positioning block 7, and a driving block 9. The positioning block 7 and the driving block 9 are arranged in sequence along the center line of the clamp body, the positioning block 7 is placed on the outside, and the top surface is connected to the ends of a pair of steering arms 6 through a rotating shaft, and the other ends of the steering arms 6 are connected to the opening and closing arms 2 on both sides through a pin shaft and a pin hole 3. Preferably, the end surface of the driving block 9 near the positioning block 7 is in a "┐" shape, and the rotating shaft of the clamp body is connected to the top surface of the driving block 9.

[0029] Preferably, an adjustment screw 8 is provided on the side of the positioning block 7 between the positioning block 7 and the driving block 9 .

[0030] The power assembly is a cylinder 10 placed on the table, and the piston rod of the cylinder 10 is fixedly connected to the driving block 9. Preferably, the table is provided with a slide groove along the center line of the clamping body, and the driving block 9 slides along the slide groove.

[0031] When using,

[0032] The cylinder 10 is started, and the piston rod pushes the driving block 9 along the center line, so that the angle between the opening and closing arms 2 increases.

[0033] After the triangular position formed by the first chuck 4 and the second chuck 5 clamps the part 1 , the cylinder 10 drives the piston rod to pull back the opening and closing arm 2 , so that the first chuck 4 and the second chuck 5 firmly clamp the part 1 .

[0034] By adjusting the length of the adjustment screw 8, the moving space of the drive block 9 relative to the positioning block 7, that is, the expansion and contraction amount of the piston, that is, the closed angle of the clamp body, can be adjusted, and the clamping force during the clamping process can be adjusted to prevent the product from being cracked or damaged due to excessive force; the opening and closing of the angle and the clamping time can be indirectly adjusted to facilitate the assembly line operation of multiple parts 1.

[0035] In actual use, the first clamp 4 and the second clamp 5 can be replaced, so that the clamp body can be suitable for parts 1 of various shapes.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
