[0048] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 12 The embodiments of the present application are described in detail.

[0049] like Figures 1 to 12 As shown, the present application provides a clamping device 1, comprising a mounting member 11, a rotating seat 12, a clamping member 13 and a driving member 14. The rotating seat 12 is rotatably mounted on the mounting member 11, and a slide groove 121 is provided on the rotating seat 12; the clamping member 13 is disposed on one side of the rotating seat 12, and the clamping member 13 comprises a first clamping portion 131 and a second clamping portion 132 spaced apart along a first preset direction X, one end of the first clamping portion 131 being movably mounted on the slide groove 121, and the other end being movably mounted on the mounting member 11 along the first preset direction X, wherein the first preset direction X does not pass through the rotation center of the rotating seat 12; the driving member 14 is drivingly connected to the rotating seat 12 to drive the rotating seat 12 to rotate.

[0050] The rotating seat 12 is rotatably arranged on the mounting member 11. Specifically, a rotating shaft can be set, one end of the rotating shaft can be rotatably inserted into the mounting member 11, and the other end is fixedly connected to the rotating seat 12. The rotation of the rotating shaft can realize the rotation of the rotating seat 12 relative to the mounting member 11.

[0051] A sliding groove 121 is provided on the rotating base 12 . When the rotating base 12 rotates relative to the mounting member 11 , the extending direction of the sliding groove 121 will also change accordingly.

[0052] The clamping member 13 is a component of the clamping device 1 used to clamp the object 2 to be clamped. The clamping member 13 includes a first clamping portion 131 and a second clamping portion 132 spaced apart along a first predetermined direction X. When the distance between the first clamping portion 131 and the second clamping portion 132 along the first predetermined direction decreases, the object 2 to be clamped is clamped and fixed; when the distance between the first clamping portion 131 and the second clamping portion 132 along the first predetermined direction increases, the object 2 to be clamped is released. The object 2 to be clamped can be any material that needs to be fixed or transported. The shape of the object 2 to be clamped corresponds to the shape of the clamping space enclosed by the first clamping portion 131 and the second clamping portion 132 to ensure effective clamping of the object 2 to be clamped.

[0053] The driving member 14 can be a motor to drive the rotating seat 12 to rotate relative to the mounting member 11; the driving member 14 can also be a cylinder, an electric cylinder, a hydraulic cylinder, a cam mechanism, etc., which drives the rotating seat 12 to rotate (i.e., swing) within a certain range relative to the mounting member 11 through linear motion.

[0054] like Figure 5 As shown, in the triangle, the distance d between the first clamping portion 131 and the second clamping portion 132 along the first preset direction X can be expressed as: d = h / tana; where h is the height difference between the first clamping portion 131 and the second clamping portion 132 in the second preset direction Y, and a is the angle between the slide groove 121 and the first preset direction X.

[0055] One end of the first clamping portion 131 is movably disposed in the slide slot 121, and the other end is movably disposed on the mounting member 11 along the first predetermined direction X. When the rotating base 12 rotates relative to the mounting member 11, the angle a between the slide slot 121 and the first predetermined direction X changes accordingly. The first clamping portion 131 and the second clamping portion 132 are spaced apart along the first predetermined direction X. That is, when the other end of the first clamping portion 131 moves relative to the mounting member 11 along the first predetermined direction X, the height difference h between the first clamping portion and the second clamping portion in the second predetermined direction Y does not change.

[0056] That is, when the rotating seat 12 rotates relative to the mounting member 11, the angle a between the slide groove 121 and the first preset direction X will change accordingly, but the height difference h between the first clamping portion 131 and the second clamping portion 132 in the second preset direction Y is constant. Therefore, the distance d between the first clamping portion 131 and the second clamping portion 132 along the first preset direction X will change with the rotation of the rotating seat 12, thereby achieving the first clamping portion 131 and the second clamping portion 132 approaching or moving away from each other along the first preset direction X by adjusting the rotation angle and direction of the rotating seat 12, thereby achieving the clamping and release of the clamping device 1.

[0057] Specifically, a first guide rail 111 extending along a first preset direction X can be provided on the mounting member 11, and a first slider 1311 can be provided on the first clamping portion 131. The other end of the first clamping portion 131 can be movably provided on the mounting member 11 along the first preset direction X by moving the first slider 1311 on the first guide rail 111.

[0058] It should be noted that, in some embodiments, one end of the first clamping portion 131 is movably provided in the slide groove 121, and the other end is movably provided on the mounting member 11 along the first preset direction X, while the second clamping portion 132 is fixedly provided on the mounting member 11 at an interval from the first clamping portion 131 along the first preset direction X. The relative positions of the two are adjusted by moving the first clamping portion 131 along the first preset direction X, thereby achieving the clamping and release of the clamping device 1. Since only the movement of the first clamping portion 131 needs to be adjusted, the clamping device 1 has good controllability.

[0059] In other embodiments, one end of the first clamping portion 131 and the second clamping portion 132 are respectively movably arranged in the slide groove 121, and the other ends are respectively spaced and movably arranged on the mounting member 11 along the first preset direction X. By simultaneously adjusting the movement of the two in the first preset direction X, the clamping and release of the clamping device 1 are achieved, and the clamping and release speed is faster and more efficient.

[0060] The first preset direction X does not pass through the rotation center of the rotating base 12 because when the first preset direction X passes through the rotation center of the rotating base 12, h in the triangle is always zero, and the relative distance between the first clamping member 131 and the second clamping member 132 along the first preset direction X cannot be adjusted.

[0061] By movably positioning one end of the first clamping portion 131 in the chute 121 and movably positioning the other end in the mounting member 11 along the first preset direction X, the rotation of the swivel seat 12 causes the extension direction of the chute 121 to change, thereby driving one end of the first clamping portion 131 to move within the chute 121 and causing the other end of the first clamping portion 131 to move along the first preset direction X away from or closer to the second clamping portion 132, thereby achieving clamping and loosening of the clamped member 2. In other words, the clamping device 1 of the present application can achieve clamping and loosening of the clamping device 1 by adjusting the rotation angle and direction of the swivel seat 12, and has a simple structure and is easy to control.

[0062] like Figure 6 As shown, in some embodiments, the clamping member 13 further includes a first roller 133 , and the first clamping portion 131 is movably disposed in the sliding groove 121 via the first roller 133 .

[0063] The first roller 133 is a member that can roll about its own axis. The first clamping portion 131 is movably disposed in the chute 121 via the first roller 133. This converts the sliding friction of the first clamping portion 131 as it moves within the chute 121 into rolling friction of the first roller 133 within the chute 121. This reduces wear between the first clamping portion 131 and the chute 121, thereby increasing the service life of the clamping device 1.

[0064] like Figure 2 and Figures 6 to 10 As shown, in some embodiments, one end of the second clamping portion 132 is movably disposed on the sliding groove 121 , and the other end is movably disposed on the mounting member 11 along the first preset direction X.

[0065] That is, the other ends of the first clamping portion 131 and the second clamping portion 132 are both movable along the first preset direction X, and the clamping and releasing of the clamping device 1 are achieved by simultaneously adjusting the movement of both in the first preset direction X. Specifically, a first guide rail 111 extending along the first preset direction X may be provided on the mounting member 11, and a second slider 1321 may be provided on the second clamping portion 132. The other end of the second clamping portion 132 is movably provided on the mounting member 11 along the first preset direction X by the movement of the second slider 1321 on the first guide rail 111.

[0066] Similarly, if Figure 5 As shown, in the triangle, the distance d between the first clamping portion 131 and the second clamping portion 132 along the first preset direction X can be expressed as: d = h / tana; where h is the height difference between the first clamping portion 131 and the second clamping portion 132 in the second preset direction Y, and a is the angle between the slide groove 121 and the first preset direction X.

[0067] One end of the first clamping portion 131 and the second clamping portion 132 are each movably disposed within the slide groove 121. When the rotating base 12 rotates relative to the mounting member 11, the angle a between the slide groove 121 and the first predetermined direction X changes accordingly. The other ends of the first clamping portion 131 and the second clamping portion 132 are each movably disposed within the mounting member 11 along the first predetermined direction X. That is, when the first clamping portion 131 and the second clamping portion 132 move relative to the mounting member 11 along the first predetermined direction X, the height difference h between the two portions in the second predetermined direction Y remains unchanged.

[0068] That is, when the rotating seat 12 rotates relative to the mounting member 11, the angle a between the slide groove 121 and the first preset direction X will change accordingly, but the height difference h between the first clamping portion 131 and the second clamping portion 132 in the second preset direction Y is constant. Therefore, the distance d between the first clamping portion 131 and the second clamping portion 132 along the first preset direction X will change with the rotation of the rotating seat 12, thereby achieving the first clamping portion 131 and the second clamping portion 132 approaching or moving away from each other along the first preset direction X by adjusting the rotation angle and direction of the rotating seat 12, thereby achieving the clamping and release of the clamping device 1.

[0069] By moving the other ends of the first clamping portion 131 and the second clamping portion 132 along the first preset direction X, the movement of both in the first preset direction X can be adjusted simultaneously to achieve clamping and releasing of the clamping device 1, with faster clamping and releasing speed and higher efficiency.

[0070] like Figure 6 As shown, in some embodiments, the clamping member 13 further includes a second roller 134, and the second clamping portion 132 is movably disposed in the sliding groove 121 via the second roller 134. The function of the second roller 134 is similar to that of the first roller 133 and will not be repeated here.

[0071] like Figure 2 、 4 As shown in Figures 6 to 10, in some embodiments, a first guide rail 111 extending along a first preset direction X is provided on the mounting member 11, a first slider 1311 is provided on the first clamping portion 131, and a second slider 1321 is provided on the second clamping portion 132. The first slider 1311 and the second slider 1321 are respectively movably provided on the first guide rail 111.

[0072] The first guide rail 111 , the first slider 1311 and the second slider 1321 are provided to realize the movement of the first clamping portion 131 and the second clamping portion 132 relative to the mounting member 11 , which has a simple structure and high reliability.

[0073] like Figure 2 、 6 as well as Figures 8 to 10 As shown, in some embodiments, the distance between the connection position of the first clamping portion 131 and the slide groove 121 and the connection position of the second clamping portion 132 and the slide groove 121 along the second preset direction Y is greater than zero and less than or equal to the length of the slide groove 121, and the second preset direction Y is perpendicular to the first preset direction X.

[0074] The distance between the connection position of the first clamping portion 131 and the slide groove 121 and the connection position of the second clamping portion 132 and the slide groove 121 along the second preset direction Y is greater than zero, that is, there is a certain height difference h between the first clamping portion 131 and the second clamping portion 132 along the second preset direction Y. According to d=h / tana, it can be seen that only when h is not zero can the distance d between the first clamping portion 131 and the second clamping portion 132 change with the change of the angle a, and the clamping and loosening of the clamping member 2 can be achieved by rotating the rotating seat 12.

[0075] However, when the distance between the connection position of the first clamping portion 131 and the slide groove 121 and the connection position of the second clamping portion 132 and the slide groove 121 along the second preset direction Y is greater than the length of the slide groove 121, the first clamping portion 131 and the second clamping portion 132 will be able to escape from the slide groove 121. Therefore, in order to ensure the normal operation of the clamping device 1, it is also necessary to ensure that the height difference between the first clamping portion 131 and the second clamping portion 132 along the second preset direction Y is less than or equal to the length of the slide groove 121.

[0076] like Figures 1 to 4 As shown, in some embodiments, the clamping device 1 further includes a connecting member 15 and a frame 16. One end of the connecting member 15 is connected to the rotating base 12, and the other end abuts the driving member 14. The driving member 14 and / or the mounting member 11 are movably disposed on the frame 16 along a second predetermined direction Y to drive the connecting member 15 to swing. The second predetermined direction Y is perpendicular to the first predetermined direction X.

[0077] One end of the connecting member 15 is connected to the rotating seat 12. Specifically, the connecting member 15 can be integrally formed with the rotating seat 12, or can be manufactured separately and then combined and connected together by welding, bolt connection, etc.

[0078] The driving member 14 and / or the mounting member 11 are movably disposed on the frame 16 along the second preset direction Y. That is, in some embodiments, one of the driving member 14 and the mounting member 11 is movably disposed on the frame 16 along the second preset direction Y; while in other embodiments, both the driving member 14 and the frame 16 are movably disposed on the frame 16 along the second preset direction Y. By movably disposing the driving member 14 and / or the mounting member 11 on the frame 16 along the second preset direction Y, the relative position of the driving member 14 and the frame 16 in the second preset direction Y can be adjusted, thereby enabling the driving member 14 and the connecting member 15 to approach and abut each other, thereby driving the rotating base 12 to swing relative to the mounting member 11.

[0079] By providing a connecting member 15, the rotating seat 12 is configured as a connecting rod rotatably provided on the frame 16. When the driving member 14 and / or the frame 16 moves along the second preset direction Y, the driving member 14 and the mounting member 11 can be brought close to each other so that the driving member 14 abuts against the connecting member 15 to push the rotating seat 12 to swing relative to the mounting member 11, thereby achieving clamping and loosening of the clamping member 2. The structure is simple and easy to control.

[0080] like Figures 1 to 4 As shown, in some embodiments, a second guide rail 161 extending along a second preset direction Y is provided on the frame 16, a third slider 141 movably connected to the second guide rail 161 is provided on the driving member 14, and / or a fourth slider 112 movably connected to the second guide rail 161 is provided on the mounting member 11.

[0081] That is, in some embodiments, a slider movably connected to the second guide rail 161 is provided on the driving member 14 or the mounting member 11. The relative distance between the driving member 14 and the mounting member 11 along the second preset direction Y is adjusted by moving the slider on the second guide rail 161. This allows the driving member 14 and the connecting member 15 to abut against each other, thereby pushing the rotating seat 12 to swing relative to the mounting member 11, thereby achieving clamping and releasing of the clamping device 1. In other embodiments, both the driving member 14 and the mounting member 11 are provided with sliders movably connected to the second guide rail 161. This can speed up the adjustment of the relative distance between the driving member 14 and the mounting member 11 along the second preset direction Y, thereby improving the working efficiency of the clamping device 1.

[0082] like Figure 11 and 12 As shown, in some embodiments, the clamping device 1 further includes a guide cam 17 provided on a side of the frame 16 away from the mounting member 11, the guide cam 17 is provided with a first guide groove 171, and the driving member 14 is provided with a first cam follower 142 accommodated in the first guide groove 171; and / or

[0083] A second guide groove 172 is provided on the guide cam, and a second cam follower 113 accommodated in the second guide groove 172 is provided on the mounting member 11 .

[0084] That is, in some embodiments, the driving member 14 is provided with a first cam follower 142 accommodated in the first guide groove 171, or the mounting member 11 is provided with a second cam follower 113 accommodated in the second guide groove 172. When the guide cam rotates, the first cam follower 142 or the second cam follower 113 moves along the second preset direction Y under the guidance of the guide groove, thereby adjusting the relative distance between the driving member 14 and the mounting member 11 along the second preset direction Y. In other embodiments, the driving member 14 is provided with a first cam follower 142 accommodated in the first guide groove 171, and the mounting member 11 is provided with a second cam follower 113 accommodated in the second guide groove 172. By setting the relative distance between the first guide groove 171 and the second guide groove 172 along the second preset direction Y, the relative distance between the driving member 14 and the mounting member 11 along the second preset direction Y can be adjusted when the guide cam rotates.

[0085] By setting the guide cam, only one power source can be used to drive the cam to rotate to achieve the relative position of the driving member 14 and / or the mounting member 11 relative to the frame 16 in the second preset direction Y. The device is simple and easy to control.

[0086] like Figures 1 to 4 As shown in Figures 6 to 10, in some embodiments, the clamping device 1 further includes a first elastic member 18, which extends along the first preset direction X, and one end of the first elastic member 18 is connected to the first clamping portion 131, and the other end is connected to the second clamping portion 132.

[0087] The first elastic member 18 is an elastic component, which can be rubber or a spring. The first elastic member 18 connects the first clamping portion 131 and the second clamping portion 132. When the clamping device 1 clamps the object 2, the first elastic member 18 provides an elastic force to increase the clamping force between the first clamping portion 131 and the second clamping portion 132, thereby improving the stability of the object 2 on the clamping device 1.

[0088] Furthermore, by providing the first elastic member 18, when the driving member 14 and the mounting member 11 approach each other along the second preset direction Y, the driving member 14 can push the rotating base 12 to rotate, thereby causing the first clamping portion 131 and the second clamping portion 132 to move away from each other, thereby opening the clamping member 13 and facilitating the loading of the to-be-clamped part 2. When loading is completed, the driving member 14 and the mounting member 11 move away from each other along the second preset direction Y, and the first clamping portion 131 and the second clamping portion 132 can approach each other along the first preset direction X under the elastic force of the first elastic member 18, thereby clamping the to-be-clamped part 2 and driving the rotating base 12 to rotate in the opposite direction and return to its initial position.

[0089] In summary, by providing the first elastic member 1217 , not only can the driving force of the clamping device 1 when clamping be omitted, but also the control of the clamping and releasing of the clamping device 1 can be made simpler and more reliable.

[0090] like Figure 8 As shown, in some embodiments, the clamping device 1 further includes a protrusion assembly 19 disposed on the first clamping portion 131 and / or the second clamping portion 132. The protrusion assembly 19 includes a protrusion 191, a rotary rod 192, and a second elastic member 193. The protrusion 191 is protrudingly disposed on the surfaces of the first clamping portion 131 and / or the second clamping portion 132 that are adjacent to each other; the rotary rod 192 is spirally disposed on the first clamping portion 131 and / or the second clamping portion 132 and is disposed corresponding to the protrusion 191; and the second elastic member 193 is disposed between the protrusion 191 and the rotary rod 192.

[0091] That is, in some embodiments, the protrusion component 19 is provided on the first clamping portion 131 or the second clamping portion 132 ; in other embodiments, the protrusion component 19 is provided on both the first clamping portion 131 and the second clamping portion 132 .

[0092] A second elastic member 193 is disposed between the protrusion 191 and the rotating rod 192, and the elastic force of the second elastic member 193 provides a floating force for the protrusion 191. The rotating rod 192 is spirally mounted on the clamping member 13. By rotating the rotating rod 192, the relative distance between the rotating rod 192 and the protrusion 191 can be adjusted, thereby adjusting the compression level of the second elastic member 193, providing different elastic forces to the protrusion 191 to adapt to different clamping conditions.

[0093] By providing the protrusion assembly 19 , the protrusion 191 can be floated on the surface of the first clamping portion 131 and / or the second clamping portion 132 close to each other, thereby being able to adapt to different sizes of the clamped parts 2 and improving the applicability of the clamping device 1 .

[0094] It should be noted that one protrusion component 19 or multiple protrusion components 19 can be provided on the first clamping portion 131 and / or the second clamping portion 132, and this embodiment of the present application does not limit this.

[0095] Specifically, such as Figures 1 to 12 As shown, before clamping, the driving member 14 and the mounting member 11 are spaced apart along the second preset direction Y, and the first clamping portion 131 and the second clamping portion 132 put the clamping member 13 in a clamped state under the action of the first elastic member 18 .

[0096] During clamping, the guide cam 17 rotates, causing the driving member 14 and the mounting member 11 to gradually approach each other along the second predetermined direction Y, guided by the first and second guide slots 171, 172. Subsequently, the driving member 14 and the mounting member 11 further approach each other, causing the driving member 14 to abut against the connecting member 15, thereby pushing the rotating base 12 to swing relative to the mounting member 11. This in turn causes the first and second clamping portions 131, 132 to gradually move apart along the first predetermined direction X, thereby releasing the clamping member 13. The object 2 to be clamped is then placed between the first and second clamping portions 131, 132. Finally, the driving member 14 and the mounting member 11 gradually move apart along the second predetermined direction Y, guided by the first and second guide slots 171, 172. Driven by the elastic force of the first elastic member 18, the first and second clamping portions 131, 132 approach each other along the first predetermined direction X, thereby clamping the object 2 to be clamped and driving the rotating base 12 to rotate in the opposite direction and return to its initial position. At this point, the clamping and fixing of the part 2 to be clamped is completed.

[0097] When the clamping device 1 cycles through loading and unloading operations, the above-described actions are repeated. The guide cam 17 rotates, causing the driving member 14 and the mounting member 11 to approach each other, causing the driving member 14 to abut against the connecting member 15, pushing the rotating base 12 to swing relative to the mounting member 11, causing the first clamping portion 131 and the second clamping portion 12 to gradually move apart in the first predetermined direction X, thereby releasing the clamping member 13. Subsequently, the material clamped in the clamping member 13 is removed, and the object 2 to be clamped is placed between the first clamping portion 131 and the second clamping portion 132. Finally, guided by the first guide slots 171 and the second guide slots 172, the driving member 14 and the mounting member 11 gradually move apart in the second predetermined direction Y. Driven by the elastic force of the first elastic member 18, the first clamping portion 131 and the second clamping portion 132 move toward each other in the first predetermined direction X, thereby clamping the object 2 to be clamped and driving the rotating base 12 to rotate in the opposite direction and return to its initial position. This reciprocating cycle continues.

[0098] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
