[0020] Figure 1 A schematic diagram of the clamping mechanism according to an embodiment of the present invention is shown. Figure 1 As shown, this utility model proposes a clamping mechanism and a processing device. The clamping mechanism of this utility model includes a fixed base 10, a clamping assembly, and an adjusting assembly. The clamping assembly includes a first jaw 21 and a second jaw 22, which are rotatably connected to the fixed base 10. The first jaw 21 and the second jaw 22 are arranged opposite to each other and elastically connected. A clamping cavity 23 is defined between the first jaw 21 and the second jaw 22. The adjusting assembly includes an adjusting member 31 and a first driving member 32 disposed on the fixed base 10. The first driving member 32 is connected to the adjusting member 31 and can drive the adjusting member 31 to move relative to the clamping assembly. The adjusting member 31 includes a first abutting part 311 and abutting part 312 spaced apart along its own axial direction. The first abutting part 311 and the second abutting part 312 can respectively abut and cooperate with the clamping assembly. The first abutting part 311 is configured to push the first jaw 21 and the second jaw 22 to rotate, and the second abutting part 312 is configured to push the first jaw 21 to rotate.

[0021] By using the clamping assembly in this technical solution, the fixed base 10 can support and fix the clamping assembly and the adjusting assembly. The adjusting member 31 can move toward the clamping assembly under the drive of the first driving member 32. The first abutting part 311 of the adjusting member 31 can push the first jaw 21 and the second jaw 22 to rotate respectively, thereby adjusting the size of the clamping cavity 23. The second abutting part 312 can only push the first jaw 21 to rotate, thereby adjusting the size of the clamping cavity 23. The clamping mechanism in this utility model can adjust the clamping cavity 23 through the pushing force of the adjusting member 31 and the elastic force between the first jaw 21 and the second jaw 22. Moreover, the first abutting part 311 and the second abutting part 312 can respectively realize two clamping methods: double jaw clamping and single jaw clamping, thereby improving the versatility and applicability of the clamping mechanism.

[0022] Specifically, in this embodiment, the first driving member 32 is a linear motor, which can drive the adjusting member 31 to move toward the clamping assembly.

[0023] Specifically, such as Figure 2As shown, in this embodiment, the adjusting member 31 is located between the first gripper 21 and the second gripper 22. It can move between the first gripper 21 and the second gripper 22 via the first driving member 32. During this movement, the first abutting part 311 and the second abutting part 312 can respectively abut against the clamping assembly. When the first abutting part 311 abuts against the first gripper 21 and the second gripper 22, it can push the first gripper 21 and the second gripper 22, causing them to rotate. The rotation of the first gripper 21 and the second gripper 22 adjusts the size of the clamping cavity 23. Similarly, the second abutting part 312 can also abut against the first gripper 21, thereby pushing the first gripper 21 and causing it to rotate. The rotation of the first gripper 21 relative to the second gripper 22 also adjusts the size of the clamping cavity 23. When the first adjusting member 31 moves away from the clamping assembly, the first gripper 21 and the second gripper 22 can return to their initial state through elastic force. In this embodiment, the initial state of the clamping assembly is open. When the adjusting member 31 acts on the clamping assembly, it will cause the clamping assembly to close, thereby achieving clamping or holding.

[0024] In some embodiments of this utility model, such as Figure 3 As shown, the first gripper 21 has a first arcuate surface on the side facing the adjusting member 31, and the first abutting part 311 has a first abutting surface 3111 on the side facing the first gripper 21. The first abutting surface 3111 and the first arcuate surface can slide together. In this embodiment, the first gripper 21 has a first abutting end on the side near the pressure sensor 313, and a first clamping end 211 on the side away from the pressure sensor 313. The first abutting end has a first arcuate surface, which facilitates sliding engagement with the first abutting surface 3111. This allows the first abutting part 311 to push the end of the first gripper 21 away from the clamping cavity 23, causing the first gripper 21 to rotate.

[0025] Specifically, in this embodiment, since the first abutting part 311 moves toward the clamping cavity 23 via the first driving member 32, and the first abutting surface 3111 and the first arc surface always abut against each other, along the direction from the clamping assembly to the adjusting assembly (i.e., Figure 2 The distance between the first abutting part 311 and the axis of the adjusting member 31 increases from the first abutting part 311 to the second abutting part 312. That is, the end of the first abutting part 3111 facing the clamping cavity 23 is biased towards the axis of the adjusting member 31. As the first abutting part 311 moves, the pushing of the first abutting part 3111 on the first clamping end 211 is increased, thereby accelerating the rotation of the first gripper 21 and improving the clamping speed of the first gripper 21.

[0026] In some embodiments of this utility model, such as Figure 3As shown, the second gripper 22 has a second arcuate surface on the side facing the adjusting member 31, and the first abutting portion 311 has a second abutting surface on the side facing the second gripper 22. The second abutting surface and the second arcuate surface can slide together. In this embodiment, the second gripper 22 has a second abutting end on the side near the pressure sensor 313 and a second abutting end on the side away from the pressure sensor 313. The second abutting end has a second arcuate surface, and a clamping cavity 23 is formed between the first clamping end 211 and the second clamping end 221. The second arcuate surface facilitates sliding engagement with the second abutting surface, thereby facilitating the first abutting portion 311 to push the second abutting end of the second gripper 22, causing the second gripper 22 to rotate. The combination structure of the first abutting portion 311, the first arcuate surface, and the second arcuate surface in this embodiment is similar to a cam structure.

[0027] Specifically, in this embodiment, since the first abutting part 311 moves toward the clamping cavity 23 via the first driving member 32, and the second abutting surface and the second arc surface always abut against each other along the direction from the clamping assembly to the adjusting assembly (i.e., Figure 2 The distance between the second abutment surface and the axis of the adjusting member 31 increases from the first abutment portion 311 to the second abutment portion 312. That is, the end of the second abutment surface facing the clamping cavity 23 is biased towards the axis of the adjusting member 31. As the first abutment portion 311 moves, the pushing force of the second abutment surface on the second clamping end 221 is increased, thereby causing the second gripper 22 to rotate faster and increasing the clamping speed of the second gripper 22.

[0028] In some embodiments of this utility model, such as Figure 3 As shown, the second abutment portion 312 has a third abutment surface 3121 on the side facing the first gripper 21, and the third abutment surface 3121 can slide with the first arc surface. When the second abutment portion 312 acts on the first gripper 21, the first arc surface can easily slide with the third abutment surface 3121, thereby facilitating the second abutment portion 312 to push the end of the first gripper 21 away from the clamping cavity 23, causing the first gripper 21 to rotate.

[0029] Specifically, in this embodiment, since the second abutting part 312 moves toward the clamping cavity 23 via the first driving member 32, and the third abutting surface 3121 and the first arc surface always abut against each other, along the direction from the clamping assembly to the adjusting assembly (i.e., Figure 2 The distance between the third abutment surface and the axis of the adjusting member 31 increases from the first abutment portion 311 to the second abutment portion 312. That is, the end of the third abutment surface 3121 facing the clamping cavity 23 is biased towards the axis of the adjusting member 31. As the third abutment portion moves, the third abutment surface 3121 pushes the first clamping end 211 more, thereby accelerating the rotation of the first clamping jaw 21 and increasing the clamping speed of the first clamping jaw 21.

[0030] In some embodiments of this utility model, such as Figure 3 As shown, the cross-sections of the first abutment portion 311 and the second abutment portion 312 intersect. In this embodiment, the first abutment portion 311 is a triangular prism structure, with its tip facing the clamping cavity 23. A first abutment surface 3111 and a second abutment surface are respectively connected to both sides of the tip. The cross-section of the first abutment portion 311 is triangular. The second abutment portion 312 is a quadrangular prism structure, with a right-angled trapezoidal cross-section. The second abutment portion 312 has a third abutment surface 3121 and a first plane 3122 on both sides along the first direction. The first plane 3122 is always spaced apart from the second gripper 22. The first direction is the axial direction of the adjusting member 31. As the adjusting member 31 moves towards the clamping assembly, the first plane 3122 will not contact the second gripper 22, thus achieving single-gripper clamping.

[0031] Specifically, since both the first abutment portion 311 and the second abutment portion 312 are columnar structures with relatively small heights, the cross-sections of the first abutment portion 311 and the second abutment portion 312 are arranged perpendicularly to ensure that when the first abutment portion 311 interacts with the clamping component, the second abutment portion 312 will not interfere with the clamping component, and when the second abutment portion 312 interacts with the clamping component, the first abutment portion 311 will not interfere with the clamping component.

[0032] In some embodiments of this utility model, such as Figure 1 As shown, the adjustment assembly also includes a second driving member 33, which is connected to the first driving member 32 and the adjusting member 31 respectively. The first driving member 32 is configured to drive the second driving member 33 and the adjusting member 31 to move relative to the clamping assembly, and the second driving member 33 is configured to drive the adjusting member 31 to rotate about its own axis. In this embodiment, the second driving member 33 is a rotary motor. The first driving member 32 can drive the second driving member 33 and the adjusting member 31 to move toward or away from the clamping assembly, thereby realizing the abutment cooperation between the first abutment portion 311 and the second abutment portion 312 and the clamping assembly, and finally realizing single-jaw clamping (i.e., the first jaw 21 moves toward or away from the second jaw 22) and double-jaw clamping (i.e., the first jaw 21 and the second jaw 22 move relative to each other).

[0033] Specifically, such as Figure 1 As shown, in this embodiment, the second driving member 33 is provided with a slide rail, and the fixed base 10 is provided with a slide rail 34, with the slide rail 34 and the slide rail slidingly engaged. The first driving member 32 can be fixedly connected to the slide rail 34 or to the fixed base 10.

[0034] Specifically, in this embodiment, the second driving member 33 can also drive the adjusting member 31 to rotate around itself, thereby changing the direction of the cross-section of the first abutment portion 311 and the second abutment portion 312. For example, as Figure 4 As shown, when the first driving member 32 drives the second driving member 33 and the adjusting member 31 to move toward the clamping assembly, the first abutting part 311 will first abut against the first jaw 21 and the second jaw 22 respectively and push the first jaw 21 and the second jaw 22 to rotate respectively, realizing the relative movement of the first jaw 21 and the second jaw 22, and realizing the double-jaw clamping operation. Figure 5 As shown, when only the first gripper 21 needs to rotate, the second drive member 33 can rotate the adjusting member 31, so that the cross-section of the first abutment portion 311 is perpendicular to the horizontal plane, and the cross-section of the second abutment portion 312 is parallel to the horizontal plane. Then, the first drive member 32 drives the second drive member 33 and the adjusting member 31 to move towards the clamping assembly. Since the cross-section of the first abutment portion 311 is perpendicular to the horizontal plane, it will not interfere with the first gripper 21 and the second gripper 22. Furthermore, the third abutment surface 3121 of the second abutment portion 312 will abut against the first gripper 21, causing the first gripper 21 to rotate, thus realizing a single-gripper clamping operation.

[0035] Furthermore, in this embodiment, the second drive member 33 can automatically achieve the cooperation between the clamping component and the first abutment part 311 and the second abutment part 312 respectively, thereby improving the degree of automation and reliability.

[0036] In some embodiments of this utility model, such as Figure 1 As shown, the adjusting member 31 includes a first connecting rod, a pressure sensor 313, and a second connecting rod 315. The first connecting rod includes a first connecting portion 3141 and a second connecting portion 3142. The pressure sensor 313 is connected to the first connecting portion 3141 and the second connecting portion 3142 at both ends along the axial direction of the adjusting member 31. The first connecting portion 3141 is connected to the first driving member 32. The first abutment portion 311, the second connecting rod 315, the second abutment portion 312, and the second connecting portion 3142 are connected sequentially. In this embodiment, the pressure sensor 313 between the first connecting portion 3141 and the second connecting portion 3142 can measure the thrust of the first driving member 32 on the adjusting member 31. When the thrust is greater, the clamping force of the clamping assembly will also be greater. Therefore, the magnitude of the clamping force can be calculated by observing the value of the pressure sensor 313. When the adjusting member 31 moves in the opposite direction to the clamping assembly, the elastic member 24 between the first clamp 21 and the second clamp 22 recovers its elastic force, thereby opening the first clamp 21 and the second clamp 22. In this embodiment, the elastic member 24 can be a spring.

[0037] In some embodiments of this utility model, such as Figure 1As shown, the clamping assembly includes an elastic element 24, with its two ends connected to a first gripper 21 and a second gripper 22, respectively. The elastic element 24 is configured to move the first gripper 21 and the second gripper 22 away from each other. In this embodiment, initially, the adjusting member 31 is not in contact with the clamping assembly. At this time, the elastic element 24 can open the first gripping end 211 of the first gripper 21 and the second gripping end 221 of the second gripper 22 by a certain angle, which is the maximum angle. When the adjusting member 31 moves towards the first gripper 21 and the second gripper 22 of the clamping assembly, since the first abutting part 311 is located at the head of the adjusting member 31, it can first abut against the first gripper 21 and the second gripper 22, and push the first abutting end of the first gripper 21 and the second abutting end of the second gripper 22 to rotate. This causes the first gripping end 211 and the second gripping end 221 of the first gripper 21 to move relative to each other, causing the clamping assembly to close, thereby clamping the product in the clamping cavity 23 with two grippers.

[0038] Specifically, such as Figure 5 As shown, if only the first gripper 21 needs to be rotated, the adjusting member 31 needs to be rotated 90° around its own axis by the second driving member 33 before it comes into contact with the clamping assembly. This allows the first abutting part 311 to be set vertically and the second abutting part 312 to be set parallel. At this time, the first abutting part 311 will not interfere with the first gripper 21 and the second gripper 22 under the drive of the first driving member 32. As the adjusting member 31 moves, the second abutting part 312 will come into contact with the first gripper 21 and push the first gripper 21 to rotate, thus achieving single gripper clamping.

[0039] Specifically, in this embodiment, such as Figure 6 As shown, the second driving member 33 can rotate the adjusting member 31 clockwise by 90° to perform single-jaw clamping on the second gripper 22, such as... Figure 5 As shown, the second drive member 33 can rotate the adjustment member 31 counterclockwise by 90° so that only the first gripper 21 can be gripped by a single gripper.

[0040] In some embodiments of this utility model, the middle part of the first gripper 21 and the middle part of the second gripper 22 are rotatably connected to the fixed base 10, thereby facilitating the rotation of the first gripper 21 when the adjusting member 31 pushes the first abutting end of the first gripper 21 (or the rotation of the second gripper 22 when the adjusting member 31 pushes the second abutting end of the second gripper 22). A clamping cavity 23 is formed between one end of the first gripper 21 (i.e., the first clamping end 211) and one end of the second gripper 22 (i.e., the second clamping end 221). The other end of the first gripper 21 (i.e., the first abutting end) can abut against the first abutting part 311 and the second abutting part 312 respectively, and the other end of the second gripper 22 (i.e., the second abutting end) can abut against the first abutting part 311.

[0041] Furthermore, in this embodiment, the first gripper 21 has a first limiting portion on the side opposite to the second gripper 22, and the fixing base 10 is provided with a first limiting groove. The first limiting portion is slidably disposed in the first limiting groove. When the first limiting portion contacts one extreme position of the first limiting groove, the first gripper 21 is arranged parallel to the adjusting member 31. At this time, the first clamping end 211 of the first gripper 21 will no longer rotate toward the second gripper 22, preventing the first gripper 21 from contacting the second gripper 22. It can also prevent the elastic member 24 from pulling the first gripper 21 toward the second gripper 22 when the adjusting member 31 only pushes the second gripper 22, thus improving reliability. Similarly, the second gripper 22 has a third limiting part on the side opposite to the first gripper 21, and the fixing base 10 is provided with a fourth limiting groove. The third limiting part is slidably disposed in the fourth limiting groove. When the third limiting part contacts one extreme position of the fourth limiting groove, the second gripper 22 is arranged parallel to the adjusting member 31. At this time, the second clamping end 221 of the second gripper 22 will no longer rotate toward the first gripper 21, preventing the first gripper 21 from contacting the second gripper 22. It can also prevent the elastic member 24 from pulling the second gripper 22 toward the first gripper 21 when the adjusting member 31 only pushes the first gripper 21, thus improving reliability.

[0042] Furthermore, in this embodiment, such as Figure 2 As shown, the first gripper 21 has a first rotating hole, and the second gripper 22 has a second rotating hole. The clamping mechanism also includes a first rotating shaft 25 and a second rotating shaft 26. The first rotating shaft 25 passes through the first rotating hole and is connected to the fixed base 10, and the second rotating shaft 26 passes through the second rotating hole and is connected to the fixed base 10. The clamping mechanism also includes a cover plate 40, which covers the side of the first gripper 21 and the second gripper 22 facing away from the fixed base 10, and can prevent the first gripper 21 and the second gripper 22 from detaching from their respective first rotating shaft 25 and second rotating shaft 26. The cover plate 40 and the fixed base 10 can be connected by bolts.

[0043] Specifically, in this embodiment, bearings or bushings can be provided between the first rotating hole and the first rotating shaft 25, as well as between the second rotating hole and the second rotating shaft 26, to increase wear resistance.

[0044] Furthermore, the clamping mechanism of this invention can control the opening and closing angles of the clamping components and adjust the clamping force when the clamping components are closed. It can also achieve both single-jaw and double-jaw clamping methods.

[0045] This utility model also proposes a processing device having the above-mentioned clamping mechanism.

[0046] By using the clamping mechanism of the processing device in this technical solution, the fixed base 10 can support and fix the clamping component and the adjusting component. The adjusting component 31 can move toward the clamping component under the drive of the first driving component 32. The first abutting part 311 of the adjusting component 31 can push the first jaw 21 and the second jaw 22 to rotate respectively, thereby adjusting the size of the clamping cavity 23. The second abutting part 312 can only push the first jaw 21 to rotate, thereby adjusting the size of the clamping cavity 23. The clamping mechanism in this utility model can adjust the clamping cavity 23 through the pushing force of the adjusting component 31 and the elastic force between the first jaw 21 and the second jaw 22. Moreover, the first abutting part 311 and the second abutting part 312 can respectively realize two clamping methods: double jaw clamping and single jaw clamping, thereby improving the versatility and applicability of the clamping mechanism.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
