For example, in order to avoid the adverse effect of vibration on the accuracy of the cut structure, the part to be cut needs to be clamped in a small space to keep it stable. At present, there is still a lack of clamping devices that can better achieve this goal. Utility Model Content

[0015] In the above design, the second driving member is connected to the connecting member through the pulling member, so as to facilitate repair and replacement when the second driving member or the pulling member is damaged; in addition, when the second driving member applies a pulling force to the connecting member through the pulling member, the swinging member can move in an arc through the rotational connection of the connecting member, thereby releasing the workpiece and avoiding the workpiece, thereby facilitating the removal of the workpiece and reducing the risk of interference between the workpiece and the swinging member during the removal process.
[0016] In an optional embodiment of the clamping device, the clamping device also includes a stop assembly, which is arranged on the mounting member, and the stop assembly includes a stop portion, which can move to the side of the swinging member away from the pressing member when the swinging member contacts the second surface, so as to limit the swinging member from rotating in a direction away from the pressing member.
[0017] In the above design, the stop portion can limit the swinging member when the swinging member contacts the second surface, thereby reducing the risk of the workpiece loosening due to the movement of the swinging member, which is beneficial to improving the stability of the workpiece clamping and improving the quality of the workpiece processing in subsequent operations.
[0018] In an optional implementation of the clamping device, a receiving groove is provided on the swinging member, and the receiving groove is used to receive the stop portion.
[0019] In the above design, by providing an accommodating groove, the stop portion can be arranged closer to the mounting member, and further the entire stop assembly can be arranged closer to the mounting member, so that the structure of the clamping device is more compact; at the same time, the cooperation between the stop portion and the accommodating groove can make the stop portion and the swinging member limit each other, reduce the risk of relative sliding between the stop portion and the swinging member, and further improve the stability of the workpiece clamping.
[0020] In an optional implementation of the clamping device, the stop assembly further includes a second guide member, the second guide member is connected to the mounting member, and the second guide member is slidably connected to the stop portion.
[0021] In the above design, by setting up a second guide member, the movement path of the stop part can be guided to improve the stability of the movement process of the stop part. At the same time, the second guide member is also connected to the mounting member, which can have a certain load-bearing effect on the stop part and reduce the possibility of damage to the stop part due to excessive force.
[0022] In an optional implementation of the clamping device, the pressing member and the swinging member are both configured to be long strips.
[0023] In the above design, by configuring the pressing member and the swinging member to be in a long strip shape, it is beneficial to increase the contact area between the pressing member and the swinging member and the workpiece, thereby improving the clamping effect on the workpiece.

[0063] The embodiments of the present application are further described below in conjunction with the accompanying drawings.
[0064] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a clamping device, including a mounting member 10, a pressing member 20, a rotating member 30, a swinging member 40, a connecting member 50, a first driving assembly 60 and a second driving assembly 70.
[0065] The mounting member 10 provides a mounting position for other components to form an integral structure.
[0066] The pressing member 20 is disposed on the mounting member 10 and is used to contact the first surface 101 of the workpiece 100; the swinging member 40 is connected to the rotating member 30, and the rotating member 30 is rotatably connected to the mounting member 10, so that the swinging member 40 can rotate in an arc track with the rotating member 30 as a radius. After the swinging member 40 rotates to contact the second surface 102 of the workpiece 100, it can clamp the workpiece 100 from two opposite surfaces of the workpiece 100 together with the pressing member 20. Among them, the first surface 101 and the second surface 102 are respectively located on two opposite sides of the workpiece 100.
[0067] The first driving component 60 is arranged on the mounting member 10, and is used for applying a driving force to the swinging member 40, so that the swinging member 40 makes an arc motion close to the pressing member 20; the second driving component 70 is arranged on the mounting member 10, and the second driving component 70 is rotatably connected to the connecting member 50, and the connecting member 50 is rotatably connected to the swinging member 40. The second driving component 70 can apply a pulling force to the swinging member 40 through the connecting member 50, so that the swinging member 40 makes an arc motion away from the pressing member 20.
[0068] By clamping the workpiece 100 with the swing member 40 in an arc trajectory and releasing the workpiece 100 along the arc trajectory, the clamping device can be used in scenes with narrow space, reducing the risk of movement of the workpiece 100 and facilitating other processing steps for the workpiece 100.
[0069] It is worth mentioning that the clamping device performs excellently when clamping thin plate workpieces.
[0070] Please refer to Figure 3 and Figure 4 , the working process of the clamping device in this embodiment is:
[0071] Before clamping, the swing member 40 is located at the initial position (eg Figure 3As shown in the figure, at this time, the swing member 40 is located at the end of its movement path away from the pressing member 20, and the clamping device and the workpiece 100 to be clamped are close to each other to shorten the distance between the pressing member 20 and the workpiece 100. According to the processing requirements, the clamping device can be close to the workpiece 100, or the workpiece 100 can be close to the clamping device, or the two can move towards each other to approach each other. After the pressing member 20 contacts the first surface 101 of the workpiece 100, the first driving assembly 60 pushes the swing member 40 to approach the pressing member 20, and the swing member 4 The movement path of the swing member 40 is guided by the rotating member 30 and presents an arc shape, and the arc shape is an arc shape with the distance from the rotation center of the rotating member 30 and the mounting member 10 to the connection position of the rotating member 30 and the swing member 40 as the radius. This movement path can reduce the risk of the swing member 40 contacting with the workpiece 100 and pushing the workpiece 100 during the movement, and reduce the risk of the movement of the swing member 40 being interfered. The swing member 40 moves to contact the second surface 102 of the workpiece 100, thereby clamping the workpiece 100 together with the pressing member 20 (such as Figure 4 );
[0072] When the clamping state needs to be released, the first driving assembly 60 is reset to release the thrust on the swing member 40, and the second driving assembly 70 pulls the swing member 40 through the connecting member 50, so that the swing member 40 moves in an arc away from the pressing member 20 until the swing member 40 returns to the initial position (such as Figure 3 ), at this time, the swing member 40 avoids the workpiece 100 so that the workpiece 100 can be removed from the clamping device.
[0073] In one embodiment, please refer to Figure 5 A first inclined surface 41 is provided on the swinging member 40 , and the driving force applied by the first driving assembly 60 acts on the first inclined surface 41 .
[0074] When the driving force applied by the first driving component 60 acts on the first inclined surface 41, a component force can be generated, thereby driving the swing member 40 to move along an arc trajectory, and the component force includes a clamping force perpendicular to the second surface 102. When the swing member 40 contacts the second surface 102, the clamping force can make the swing member 40 better press against the second surface 102 to improve the clamping stability.
[0075] In one embodiment, the first driving assembly 60 includes a second inclined surface, and the second inclined surface is used to contact and cooperate with the first inclined surface 41 .
[0076] The second inclined surface is used to contact and cooperate with the first inclined surface 41. On the one hand, it is convenient for the first driving component 60 to apply a driving force to the first inclined surface 41. On the other hand, in the process of the first driving component 60 pushing the swinging member 40, the contact area between the first inclined surface 41 and the second inclined surface gradually increases, so that the contact between the first driving component 60 and the swinging member 40 is more stable. When the swinging member 40 contacts the workpiece 100, it is beneficial to improve the limiting effect on the workpiece 100.
[0077] Please refer to Figure 1 In one embodiment, the first driving assembly 60 includes a first driving member 61 , and the second inclined surface is disposed on an output end of the first driving member 61 .
[0078] Directly arranging the second inclined surface on the output end of the first driving member 61 can reduce the number of components and simplify the structure, compared with connecting another component to the output end of the first driving member 61 and arranging the second inclined surface on this component.
[0079] In one embodiment, the first driving component 60 further includes a pushing member 62 , and the pushing member 62 is disposed on the output end of the first driving member 61 .
[0080] The pushing member 62 is arranged on the output end of the first driving member 61 , so when the pushing member 62 or the first driving member 61 is damaged, it is easy to repair and replace, thus saving costs.
[0081] In one embodiment, when the first drive assembly 60 includes the first drive member 61 and the push member 62, the second inclined surface is provided on the push member 62. When the second inclined surface is severely worn, the first drive assembly 60 can be maintained by replacing the push member 62, which is conducive to cost saving.
[0082] In one embodiment, the first driving assembly 60 further includes a first guide member 63 , the first guide member 63 is connected to the mounting member 10 , and the first guide member 63 is slidably connected to the pushing member 62 .
[0083] By setting the first guide member 63 to guide the movement path of the pushing member 62, it is beneficial to improve the stability of the movement process of the pushing member. At the same time, the first guide member 63 is connected to the mounting member 10, which is beneficial to exert a certain load-bearing effect on the pushing member 62 and reduce the possibility of damage to the first driving member 61 and the pushing member 62 due to excessive force.
[0084] In one embodiment, a first guide hole is formed on the first guide member 63, and the push member 62 can be slidably inserted into the first guide hole. The first guide hole can guide and limit the push member 62, which can improve the stability of the movement of the push member 62 on the one hand, and on the other hand, the hole wall of the first guide hole can bear the force of the push member 62, thereby reducing the possibility of damage to the push member 62 due to excessive force, and also helps to reduce the risk of deformation of the output end of the first driving member 61 due to excessive force.
[0085] In one embodiment, the first guide member 63 is provided with a first guide rail, and the push member 62 is provided with a first slide groove, and the push member 62 is slidably connected to the first guide member 63 through the sliding cooperation between the first slide groove and the first guide rail.

[0086] Please refer to Figure 6 In one embodiment, the second driving assembly 70 includes a second driving member 71 and a pulling member 72. The pulling member 72 is disposed on the output end of the second driving member 71, and the pulling member 72 is rotatably connected to the connecting member 50. The second driving member 71 is connected to the connecting member 50 through the pulling member 72, so that it is convenient to repair and replace the second driving member 71 or the pulling member 72 when it is damaged. In addition, when the second driving member 71 applies a pulling force to the connecting member 50 through the pulling member 72, the swinging member 40 can make an arc movement through the rotation connection of the connecting member 50, release the workpiece 100, and avoid the workpiece 100, so that the workpiece 100 can be removed easily, and the risk of interference between the workpiece 100 and the swinging member 40 during the removal process can be reduced.
[0087] Please refer to Figure 1 In one embodiment, the clamping device also includes a stop assembly 80, which is arranged on the mounting member 10. The stop assembly 80 includes a stop portion 82. The stop portion 82 can move to the side of the swinging member 40 away from the pressing member 20 when the swinging member 40 contacts the second surface 102, so as to limit the swinging member 40 and restrict the swinging member 40 from rotating in a direction away from the workpiece 100, thereby reducing the risk of the workpiece 100 loosening due to the movement of the swinging member 40, which is beneficial to improving the stability of the clamping of the workpiece 100 and improving the quality of processing the workpiece 100 in subsequent operations.
[0088] In one embodiment, the stopper assembly 80 includes a third driving member 81, and at least a portion of the output end of the third driving member 81 serves as a stopper 82. Directly setting the output end of the third driving member 81 as the stopper 82 can reduce the number of components and simplify the structure compared to using other components as the stopper 82.
[0089] In one embodiment, the stopper assembly 80 further includes a stopper 821, which is connected to the output end of the third driving member 81. In this case, the stopper 821 can be used as the stopper 82. Using the stopper 821 as the stopper 82 facilitates repair and replacement when the stopper 821 or the third driving member 81 is damaged.

At the same time, the second guide member 83 is also connected to the mounting member 10, which can have a certain load-bearing effect on the stop part 82, which is beneficial to reduce the possibility of damage to the stop part 82 due to excessive force.
[0092] In one embodiment, a second guide hole is formed on the second guide member 83, and the stopper 82 can be slidably inserted into the second guide hole. The second guide hole can guide and limit the stopper 82, which can improve the stability of the movement of the stopper 82 on the one hand, and the hole wall of the second guide hole can bear the force on the stopper 82, thereby reducing the possibility of damage to the stopper 82 due to excessive force.

[0105] Please refer to Figure 1In one embodiment, the clamping device further comprises a fixing member 90, the fixing member 90 is connected to the mounting member 10, and the fixing member 90 is rotatably connected to the rotating member 30. The fixing member 90 is provided to facilitate replacement of the component when it is damaged.
[0106] To summarize, in the clamping device of the present application, the mounting member provides mounting positions for other components to form an overall structure; the rotating member rotatably connects the swinging member and the mounting member, so that the swinging member can rotate in an arc trajectory relative to the mounting member, and the arc trajectory takes the rotating member as a rotation radius; the first driving component applies a driving force to the swinging member, so that the swinging member can move along the arc trajectory, and then the swinging member clamps the second side of the workpiece, and the swinging member cooperates with the pressing member to clamp the workpiece; the second driving component applies a pulling force to the swinging member through the connecting member, so that the swinging member moves away from the pressing member along the arc trajectory to release the limit on the workpiece; the workpiece is clamped by the swinging member moving in an arc trajectory, and the workpiece is released by moving along the arc trajectory, so that the clamping device can be used in scenes with narrow space, reduce the risk of workpiece movement, and facilitate other processing steps on the workpiece.
[0107] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the disclosure scope of the present application.
