Compared with the prior art, the beneficial effects of the utility model are that:

when the movable clamping jaw clamps the object, the object can clamp the movable clamping jaw, and the clamping jaw on the pneumatic finger exerts pressure on the mounting seat, so that the compression spring is compressed, and clamping force is generated to act on the clamping plate and the object. It is known from hooke's law that the force of the compression spring on the movable jaw is proportional to the amount of compression of the spring, i.e., the clamping force exerted by the movable jaw on the object increases with increasing compression of the compression spring. When grabbing large-size articles, the compression amount of the compression spring is larger, and when grabbing small-size articles, the compression amount of the compression spring is smaller. The larger the size and the heavier the weight of the same density article, the greater the clamping force required. Therefore, the multipurpose clamping jaw can adapt to various objects with different sizes, can provide clamping force with different sizes for the objects with different sizes, improves the stability of the objects, can prevent the objects from being damaged due to overlarge clamping force, and achieves the advantage of better applicability.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention will now be further described with reference to the accompanying drawings, in which:

example (b):

a multipurpose clamping jaw is shown in figures 1 and 2 and comprises a pneumatic finger 11, wherein the pneumatic finger 11 is provided with 2 clamping jaws 12. The jaw 12 is fixedly provided with a mounting seat 21, the mounting seat 21 is fixedly connected with 2 guide rods 22, and the jaw 12 is positioned between the 2 guide rods 22.

Guide arm 22 sliding connection has movable clamping jaw 31, and movable clamping jaw 31 includes grip block 34, 2 connecting rods 33 and 2 sliders 32, and 2 sliders 32 are sliding connection respectively in 2 guide arms 22, and slider 32 is located between 2 at least mount pads 21, 2 connecting rods 33 both ends respectively with grip block 34 and 2 slider 32 fixed connection, be equipped with between 2 connecting rods 33 and supply the keeping away a groove 36 that jack catch 12 passes through. One end of the guide rod 22 far away from the mounting seat 21 is fixedly connected with a limit plate 24 clamped with the slide block 32. The end of the clamping plate 34 remote from the connecting rod 33 is provided with an arc-shaped surface 35.

An elastic part is arranged between the movable clamping jaw 31 and the mounting seat 21, the elastic part is a compression spring 23, two ends of the compression spring 23 are respectively fixedly connected with the movable frame and the sliding block 32, and the guide rod 22 is sleeved with the compression spring 23.

Pneumatic finger 11 drives 2 jack catchs 12 and is close to each other, drives 2 mount pads 21 and is close to each other, and mount pad 21 drives compression spring 23, slider 32, connecting rod 33 and the grip block 34 of installing respectively in 2 jack catchs 12 department again and is close to each other to enable grip block 34 and carry the article, realize the function of snatching the article.

The embodiment has the following advantages:

when the movable jaw 31 grips an object, the object will be caught by the movable jaw 31, and the jaw 12 on the pneumatic finger 11 exerts a pressure on the mounting seat 21, causing the compression spring 23 to be compressed and generating a gripping force acting on the gripping plate 34 and the object. As can be seen from hooke's law, the force of the compression spring 23 on the movable jaw 31 is proportional to the amount of compression of the spring, i.e., the clamping force exerted by the movable jaw 31 on the object increases as the amount of compression of the compression spring 23 increases. When grabbing large-sized objects, the compression amount of the compression spring 23 is large, and when grabbing small-sized objects, the compression amount of the compression spring 23 is small. The larger the size and the heavier the weight of the same density article, the greater the clamping force required. Therefore, the multipurpose clamping jaw can adapt to various objects with different sizes, can provide clamping force with different sizes for the objects with different sizes, improves the stability of the objects, can prevent the objects from being damaged due to overlarge clamping force, and achieves the advantage of better applicability.

The supporting force is provided for the movable clamping jaw 31 through the 2 guide rods 22, and the effect of improving the stability of the movable clamping jaw 31 is achieved.

Through the setting of avoiding the position groove 36, prevent that movable clamping jaw 31 from being blocked by chuck 12, can play the effect that improves grip block 34 motion stroke, make grip block 34 can be applicable to the article of bigger size, also can play the effect that improves the suitability.

The limiting plate 24 is used for clamping the sliding block 32 at one end of the guide rod 22 far away from the mounting seat 21, so that the sliding block 32 is prevented from accidentally sliding out of the guide rod 22, and the effect of improving reliability is achieved.

Through set up arcwall face 35 on grip block 34, make grip block 34 can enough centre gripping rectangle article, also can centre gripping columniform article, play the effect that improves the suitability, also can reach the effect that improves article stability.

The compression spring 23 is sleeved on the guide rod 22, the compression spring 23 can be supported by the guide rod 22, and the compression spring 23 is guided to contract and extend along the extension direction of the guide rod 22, so that the stability of the compression spring 23 is improved, and the compression spring 23 can provide stable elastic force.

This multipurpose clamping jaw adopts simple structure just to realize snatching the not unidimensional article to can provide not equidimensional clamping-force according to the article size of difference, can snatch for the rectangle article that the width is 44 millimeters ~ 50 millimeters, also can snatch for the cylindrical article that the diameter is 44 millimeters ~ 50 millimeters, have better suitability.
