Description

Technical Field

[0001] This utility model relates to the field of flexible clamping technology, and in particular to a flexible clamping fixture with sharp edges. Background Technology

[0002] Currently, flexible clamps are widely used in various fields due to their unique clamping characteristics. For example, utility model patent CN217915364U discloses a negative pressure flexible gripper, which includes a clamping part and a connecting part made of elastic material. The clamping part includes at least two interlocking fingers for clamping. The connecting part includes a driving chamber with a communication port communicating with the driving chamber. The driving chamber includes a bottom wall and a side wall. The bottom wall is located between the fingers and arches towards the fingertips. The side walls are connected to the bases of the fingers. The thickness of the bottom wall is less than the thickness of the side walls, or the elastic modulus of the bottom wall is less than the elastic modulus of the side walls. A tension reinforcing block is connected between the side wall of each finger and the bottom wall to enhance the tensile force. While this type of flexible clamp can flexibly clamp objects, it is difficult to clamp some special objects, such as lenses, memory modules, or objects with multiple ribs. These items need to be clamped to specific parts. For example, a lens cannot be clamped directly onto the surface; it can only be clamped from the edge (side). Some memory modules are arranged vertically in the memory module box and cannot be clamped from the surface of the memory module. Therefore, they can only be clamped from the edge (side). However, because the fingers of the current flexible grippers need to be bent when clamping, the contact area between the bent fingers and the edge is very small. This results in insufficient clamping force, which may cause the item to fall and loosen. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flexible edge clamp that can better clamp objects from their edges and is suitable for clamping more objects.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a flexible clamp with an edge, comprising a clamping part and a connecting part made of elastic material. The clamping part includes at least two fingers that cooperate to form a clamping area. The connecting part includes a driving chamber and a communication port communicating with the driving chamber. The driving chamber includes a bottom wall and a side wall. The side wall is connected to the base of each finger. The thickness of the bottom wall is less than the thickness of the side wall or the elastic modulus of the bottom wall is less than the elastic modulus of the side wall. A functional structure is integrally formed or detachably installed on each finger. The functional structure includes an elastic deformation part and reinforcing parts located on both sides of the elastic deformation part. The elastic deformation part is more elastically deformable than the reinforcing parts.

[0005] As a preferred embodiment, the functional structure includes a reinforcing plate with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing portion. The reinforcing plate is detachably fixed to the finger. The reinforcing plate is covered with an elastic material, and the elastic material forms the elastic deformation portion in the area of ​​the strip-shaped opening groove.

[0006] As a preferred embodiment, a plurality of strip-shaped grooves are provided on both the front and back surfaces of the elastic deformation part, and the extending direction of the strip-shaped grooves is perpendicular to the extending direction of the strip-shaped opening groove.

[0007] As a preferred embodiment, the strip-shaped grooves on the front and back of the elastic deformation part are staggered.

[0008] As a preferred embodiment, the elastic deformation part is provided with a plurality of strip-shaped through holes, the extension direction of which is perpendicular to the extension direction of the strip-shaped opening groove.

[0009] As a preferred embodiment, the functional structure includes a reinforcing plate with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing part. The reinforcing plate is detachably fixed to the finger. The reinforcing part is provided with a plurality of elastic hoop rings. The elastic hoop rings are fitted onto the reinforcing part and span the strip-shaped opening groove. The portions of all the elastic hoop rings in the area fitted into the opening groove constitute the elastic deformation part.

[0010] As a preferred embodiment, the reinforcing part has several slots on both sides, and the elastic hoop is fitted into each slot in turn.

[0011] As a preferred embodiment, the functional structure includes a reinforcing plate with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing portion. The reinforcing plate is detachably fixed to the finger. An elastic sleeve is elastically fitted onto the reinforcing portion, and the portion of the elastic sleeve located in the strip-shaped opening groove forms the elastic deformation portion.

[0012] As a preferred embodiment, the elastic material partially covers the reinforcing plate to form a covering portion, and the exposed portion of the reinforcing plate is fixed to the outer or inner side of the finger by bolts; the covering portion is provided with a positioning surface perpendicular to the reinforcing plate, and the positioning surface is positioned and engaged with the end face of the finger.

[0013] As a preferred embodiment, the functional structure includes a reinforcing plate with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing portion. The reinforcing plate is detachably fixed to the finger. The reinforcing plate is covered with an elastic material, which forms an indented groove in the area of ​​the strip-shaped opening groove. The indented groove constitutes the elastic deformation portion.

[0014] After adopting the above technical solution, the effect of this utility model is as follows: the finger is integrally formed or detachably installed with a functional structure, which includes an elastic deformation part and reinforcing parts located on both sides of the elastic deformation part. The elastic deformation part is more elastically deformable than the reinforcing parts. Therefore, when it is necessary to clamp the edge of a lens or memory module, the elastic deformation part of the finger is directly aligned with the edge of the lens or memory module. When the finger is bent, the fingers come together, and the elastic deformation part will squeeze and wrap the edge of the lens or memory module. At this time, the elastic deformation part will undergo elastic deformation, thus wrapping the edge of the lens or memory module and completing the clamping. Therefore, this edge-flexible clamp can better clamp some sheet-like or edge-shaped objects. Of course, the elastic deformation part can also be used to wrap and clamp other irregularly shaped objects. When clamping, simply align the elastic deformation part with the object. At this time, the elastic deformation part will adapt to the shape of the object as much as possible due to its own deformation. Therefore, the edge-flexible clamp of this invention has a very wide range of adaptability.

[0015] Furthermore, since the functional structure includes a reinforcing plate, the reinforcing plate is provided with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing portion. The reinforcing plate is detachably fixed to the finger. The reinforcing plate is covered with an elastic material, and the elastic material forms the elastic deformation portion in the area of ​​the strip-shaped opening groove. Therefore, with the above structure, the elastic material can be covered on the reinforcing plate by a covering process, and the elastic material in the area of ​​the strip-shaped opening groove forms the elastic deformation portion. This solution is easy to form, and the reinforcing plate is detachably fixed to the finger, so the elastic deformation portion can be replaced by changing the functional structure.

[0016] Furthermore, since several strip-shaped grooves are provided on both the front and back surfaces of the elastic deformation part, and the extending direction of the strip-shaped grooves is perpendicular to the extending direction of the strip-shaped opening groove, the friction of the elastic deformation part can be increased by utilizing the strip-shaped grooves, thereby further improving the stability of clamping.

[0017] Furthermore, since the strip-shaped grooves on the front and back of the elastic deformation part are staggered, the staggered arrangement of the strip-shaped grooves can prevent the elastic deformation part from being too thin, and at the same time, it is convenient to form strip-shaped grooves on a relatively thin elastic deformation part.

[0018] Furthermore, since the elastic deformation part is provided with several strip-shaped through holes, and the extension direction of the strip-shaped through holes is perpendicular to the extension direction of the strip-shaped opening groove, the elastic material of the strip-shaped opening groove can be divided into multiple sheet-like structures by setting the strip-shaped through holes. These sheet-like structures are easy to elastically deform. Therefore, even if the thickness of the elastic deformation part is set to be the same as the thickness of the reinforcing part, it can still elastically deform.

[0019] Furthermore, since the functional structure includes a reinforcing plate, the reinforcing plate is provided with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing part. The reinforcing plate is detachably fixed to the finger. The reinforcing part is provided with a plurality of elastic hoops. The elastic hoops are fitted onto the reinforcing part and span the strip-shaped opening groove. The portions of all the elastic hoops in the area fitted into the opening groove constitute the elastic deformation part. Therefore, by fitting elastic hoops onto the strip-shaped opening groove, elastic deformation can also be achieved, thereby allowing the elastic deformation part to wrap around the clamped object.

[0020] Furthermore, since several slots are provided on both sides of the reinforcing part, the elastic hoop is fitted into each slot in a corresponding manner. The slots allow the elastic hoop to be installed better and prevent it from sliding on the reinforcing part.

[0021] Furthermore, since the functional structure includes a reinforcing plate, the reinforcing plate is provided with a strip-shaped opening groove extending along the length of the finger. The portions on both sides of the strip-shaped opening groove constitute the reinforcing portion. The reinforcing plate is detachably fixed to the finger. An elastic sleeve is elastically fitted on the reinforcing portion. The elastic sleeve at the portion of the strip-shaped opening groove forms the elastic deformation portion. The elastic deformation of the elastic sleeve can also be used to clamp the elastic deformation portion.

[0022] Furthermore, since the elastic material partially covers the reinforcing plate to form a covering part, the exposed part of the reinforcing plate is fixed to the outside or inside of the finger by bolts; the covering part is provided with a positioning surface perpendicular to the reinforcing plate, and the positioning surface is positioned and engaged with the end face of the finger, so that the reinforcing plate can be easily assembled using the positioning surface on the covering part.

[0036] The present invention will be further described in detail below through specific embodiments.

[0037] Example 1

[0038] like Figures 1 to 6 As shown, a flexible edge clamp includes a clamping part and a connecting part 1 made of elastic material. The clamping part includes at least two fingers 2 that cooperate to form a clamping area. The connecting part 1 includes a driving chamber and has a communication port communicating with the driving chamber. The driving chamber includes a bottom wall and a side wall. The side wall is connected to the base of each finger 2. The thickness of the bottom wall is less than the thickness of the side wall or the elastic modulus of the bottom wall is less than the elastic modulus of the side wall. A functional structure 3 is integrally formed or detachably installed on the finger 2. The functional structure 3 includes an elastic deformation part 33 and reinforcing parts 35 located on both sides of the elastic deformation part 33. The elastic deformation part 33 is more elastically deformable than the reinforcing parts.

[0039] The functional structure 3 can be integrally formed with the finger 2. When integrally formed, the functional structure 3 includes a reinforcing plate 31, which is embedded in the finger 2. The reinforcing plate 31 is provided with a strip-shaped opening groove 36 extending along the length direction of the finger 2. The parts on both sides of the strip-shaped opening groove 36 constitute the reinforcing part 35. Since the finger 2 is also an elastic material, the finger 2 is provided with a relatively thin elastic deformation part 33 in the area of ​​the strip-shaped opening groove 36. Therefore, the elastic deformation part 33 is more easily deformed than the reinforcing part 35.

[0040] Of course, if the finger 2 is not embedded in the reinforcing plate 31, the functional mechanism can be realized by changing the thickness of the finger 2. For example, a relatively thin area is set on the finger 2, which forms an elastic deformation part 33, while the areas on both sides of the elastic deformation part 33 are relatively thick areas. So when clamping, the relatively thin elastic deformation part 33 is still deformed.

[0041] Therefore, when clamping the edge of an object, the elastic deformation part 33 will contact the edge and elastically deform and wrap around the edge when the finger part 2 closes and bends, thereby completing the clamping.

[0042] In this embodiment, the functional structure 3 includes a reinforcing plate 31. The reinforcing plate 31 has a strip-shaped opening groove 36 extending along the length of the finger portion 2. The portions on both sides of the strip-shaped opening groove 36 form the reinforcing portion 35. The reinforcing plate 31 is detachably fixed to the finger portion 2, specifically with bolts in this embodiment, but other fixing methods, such as bonding, are also possible. The reinforcing plate 31 is covered with an elastic material, which forms the elastic deformation portion 33 in the area of ​​the strip-shaped opening groove 36.

[0043] The elastic deformation portion 33 has a plurality of strip-shaped grooves 34 on both its front and back surfaces, and the extending direction of the strip-shaped grooves 34 is perpendicular to the extending direction of the strip-shaped opening grooves 36. The strip-shaped grooves 34 on the front and back surfaces of the elastic deformation portion 33 are staggered.

[0044] The elastic material partially covers the reinforcing plate 31 to form a covering portion 32. The exposed portion of the reinforcing plate 31 is fixed to the outer or inner side of the finger portion 2 by bolts. The covering portion 32 is provided with a positioning surface 37 perpendicular to the reinforcing plate 31, and the positioning surface 37 is positioned and engaged with the end face of the finger portion 2. When fixed to the outer side, the distance between the elastic deformation portions 33 is larger, and when fixed to the inner side, the distance between the elastic deformation portions 33 is smaller, thus making it suitable for clamping objects of different sizes.

[0045] from Figure 1 and Figure 2It can be observed that the functional structure 3 can be fixed on the inner or outer side of the finger 2. At the same time, since there are strip-shaped grooves 34 on both sides, the strip-shaped grooves 34 can contact the object no matter how they are installed. Furthermore, since the strip-shaped grooves 34 are staggered, the original thickness of the covering part 32 is relatively thin. When the strip-shaped grooves 34 are staggered, they can be better formed, avoiding the elastic deformation part 33 from being too thin.

[0046] Example 2

[0047] like Figure 7 As shown, the structure of this embodiment is basically the same as that of Embodiment 1. However, in this embodiment, the elastic deformation part 33 is provided with several strip-shaped through holes 38. The extending direction of the strip-shaped through holes 38 is perpendicular to the extending direction of the strip-shaped opening groove 36. Due to the presence of the strip-shaped through holes 38, elastic strips are formed on the plate surface between the strip-shaped through holes 38, thus facilitating the deformation of these elastic strips. In use, when the elastic deformation part 33 contacts the edge, the elastic strips will deform and wrap around the object when the finger part 2 bends.

[0048] Example 3

[0049] like Figure 8 As shown, the structure in this embodiment is basically the same as that in Embodiment 1, except that...

[0050] The functional structure 3 includes a reinforcing plate 31 with a strip-shaped opening groove 36 extending along the length of the finger 2. The portions on both sides of the strip-shaped opening groove 36 form the reinforcing part 35. The reinforcing plate 31 is detachably fixed to the finger 2. The reinforcing part 35 has several elastic hoop rings 39, which are fitted onto the reinforcing part 35 and span the strip-shaped opening groove 36. The portions of all elastic hoop rings 39 within the area fitted into the opening groove form the elastic deformation part 33. Several slots are provided on both sides of the reinforcing part 35, and the elastic hoop rings 39 are fitted into these slots one by one. These slots can be arc-shaped grooves, preventing the elastic hoop rings 39 from easily falling out. The elastic hoop rings 39 themselves are elastic, and combined with the strip-shaped opening groove 36, they can deform within the area of ​​the groove, facilitating object clamping.

[0051] Example 4

[0052] like Figure 9 and Figure 10As shown, in this embodiment, the functional structure 3 includes a reinforcing plate 31. The reinforcing plate 31 has a strip-shaped opening groove 36 extending along the length of the finger portion 2. The portions on both sides of the strip-shaped opening groove 36 constitute the reinforcing portion 35. The reinforcing plate 31 is detachably fixed to the finger portion 2. An elastic sleeve 310 is elastically fitted onto the reinforcing portion 35. The elastic sleeve 310, located at the portion of the strip-shaped opening groove 36, forms the elastic deformation portion 33. The elastic sleeve 310 is directly fitted onto the reinforcing portion 35. Since the elastic sleeve 310 itself is elastic, it can also elastically deform at the strip-shaped opening groove 36 to wrap around an object.

[0053] In embodiments 1 to 4, the flexible clamp has two fingers 2, which can be used to clamp sheet-like materials, such as lenses and memory modules, with the clamping position being from the edge (side). Of course, for objects with many edges, such as triangular or quadrangular glass, the number of flexible fingers 2 can be increased to cooperate with the edges of the object for clamping.

[0054] The elastic material in this embodiment can be silicone. The reinforcing plate 31 can be a metal reinforcing plate 31 or a plastic reinforcing plate 31.

[0055] This flexible clamp can not only hold some objects with edges, but also wrap other shaped objects, such as bottle-shaped items, when the area of ​​the elastic deformation part 33 is large.

[0056] Example 5

[0057] The structure of this embodiment is basically the same as that of Embodiment 1, except that in this embodiment, the functional structure includes a reinforcing plate 31. The reinforcing plate 31 has a strip-shaped opening groove 36 extending along the length of the finger. The portions on both sides of the strip-shaped opening groove 36 constitute the reinforcing portion. The reinforcing plate is detachably fixed to the finger. The reinforcing plate 31 is covered with an elastic material, and the elastic material forms an indented groove in the area of ​​the strip-shaped opening groove. This indented groove constitutes the elastic deformation portion 33. This elastic deformation portion is formed by the elastic material being recessed in the strip-shaped opening groove. This indented groove makes the thickness of the elastic material in this area thinner, making it more easily deformable, thus forming the elastic deformation portion 33.

[0058] The pneumatic system, servo motor, gear transmission mechanism, and lead screw and nut mechanism mentioned in this embodiment are all conventional technologies. The 5th edition of the "Mechanical Design Handbook," published in Beijing in April 2008 (5th edition, 28th printing), details the specific structure, principles, and other designs of cylinders, motors, and other transmission mechanisms, which are existing technologies with clear and straightforward structures. The 3rd edition of "Modern Practical Pneumatic Technology" (SMC Training Material), published by the Machinery Industry Press on August 1, 2008, also details vacuum components, gas circuits, and program control, indicating that the pneumatic structure in this embodiment is also existing technology and clear and straightforward. The book "Motor Drive and Speed ​​Regulation," published by the Chemical Industry Press on July 1, 2015, also details motor control and limit switches. Therefore, the circuit and pneumatic connections are clear.
