In a traditional rotary clamping device, when it is necessary to clamp components of cross-flow fan blades with different sizes, it is usually necessary to replace the clamping jaws of the rotary clamping device to match the size of the components, resulting in a slow welding process for cross-flow fan blades and low automation.

Since each first guiding hole extends from the middle of the first guiding disk to the edge of the first guiding disk, and at least part of each clamping jaw component is inserted into a first guiding hole, when the first guiding hole rotates around the preset direction, the first guiding hole can drive the clamping jaw component connected thereto to move towards the middle of the first guiding disk, or drive the clamping jaw component connected thereto to move towards the edge of the first guiding disk. Moreover, a plurality of clamping jaw components move towards the middle of the first guiding disk at the same time, or move towards the edge of the first guiding disk at the same time. When a plurality of clamping jaw components move towards the middle of the first guiding disk at the same time, the plurality of clamping jaw components approach each other, and the function of grasping components can be realized.

[0041] Referring to Figure 1 , Figure 2 and Figure 3 As shown, the rotary clamping device involved in the embodiment of the present application includes: a first driving assembly 100, a guiding assembly 200, a plurality of jaw assemblies 300, and a second driving assembly 400.

[0042] Specifically, the guiding assembly 200 includes a first guiding disc 210. The first driving assembly 100 is drivingly connected to the first guiding disc 210 and drives the first guiding disc 210 to rotate in a preset direction. The first guiding disc 210 is provided with a plurality of first guiding holes 211 that are spaced apart in the preset direction. Each first guiding hole 211 extends from the middle of the first guiding disc 210 towards the edge of the first guiding disc 210; a plurality of jaw assemblies 300 are spaced apart in the preset direction, and at least a part of each jaw assembly 300 is inserted into one of the first guiding holes 211 and contacts the hole wall of the first guiding hole 211; the second driving assembly 400 is drivingly connected to the guiding assembly 200 and the plurality of jaw assemblies 300, and drives the guiding assembly 200 and the plurality of jaw assemblies 300 to rotate in the preset direction.

[0043] It should be noted that the preset direction is Figure 1 the direction indicated by x in

[0044] In the above-mentioned rotary clamping device, the first driving component 100 can drive the first guide disk 210 to rotate around a preset direction, so that the first guide disk 210 drives a plurality of first guide holes 211 to rotate around the preset direction at the same time. Since each first guide hole 211 extends from the middle of the first guide disk 210 to the edge of the first guide disk 210, and at least part of each jaw component 300 is disposed in a first guide hole 211, when the first guide hole 211 rotates around the preset direction, the first guide hole 211 can drive the jaw component 300 connected thereto to move toward the middle of the first guide disk 210, or drive the jaw component 300 connected thereto to move toward the edge of the first guide disk 210, and a plurality of jaw components 300 move toward the middle of the first guide disk 210 at the same time, or move toward the edge of the first guide disk 210 at the same time. When a plurality of jaw components 300 move toward the middle of the first guide disk 210 at the same time, the plurality of jaw components 300 approach each other, and the function of grasping parts can be realized. When a plurality of jaw components 300 move toward the edge of the first guide disk 210 at the same time, the plurality of jaw components 300 move away from each other, and the function of releasing parts can be realized. Further, the first driving component 100 can be used to determine the rotation angle of the first guide disk 210 around the preset direction, so as to determine the rotation angle of a plurality of first guide holes 211 around the first direction, thereby determining the relative distance between a plurality of gripper components, so as to realize the function of grasping parts of different sizes of cross-flow fan blades. And this grasping process can improve the efficiency of grasping parts of different sizes of cross-flow fan blades without manually replacing the jaw component 300. At the same time, since the second driving component 400 can drive the guide component 200 and a plurality of jaw components 300 to rotate around a preset direction, when the above-mentioned rotary clamping device clamps a part to the welding station, if it is necessary to rotate the angle of the part, the second driving component 400 can be used to drive the guide component 200 and a plurality of jaw components 300 to rotate around the preset direction, and the rotation of the part can be realized, so that the part can be placed on the welding station at a preset angle.

[0045] Referring to Figure 4 As shown, in the circumferential direction of the first guide disk 210, the interval distance between any two adjacent first guide holes 211 is equal. In the radial direction of the first guide disk 210, the distance between one end of each first guide hole 211 close to the middle of the first guide disk 210 and the rotation axis of the first guide disk 210 is equal, and the distance between one end of each first guide hole 211 close to the edge of the first guide disk 210 and the edge of the first guide disk 210 is equal.

[0046] Specifically, each first guide hole 211 is a first guide hole, and the arc directions of each first guide hole are the same.

[0047] It should be noted that in the structure of the cross-flow fan blade, most of the components are circular or cylindrical.

[0048] In this embodiment, a plurality of first guiding holes 211 can be evenly distributed on the first guiding disk 210 at the circumference sharing the same rotation axis with the first guiding disk 210. When the first guiding disk 210 drives the plurality of first guiding holes 211 to rotate simultaneously in a preset direction, a plurality of jaw assemblies 300 can be evenly distributed at the circumference sharing the same rotation axis with the first guiding disk 210, so that the distance between each jaw assembly 300 and the rotation axis of the first guiding disk 210 is equal. In this way, when gripping components of cross-flow fan blades with different sizes, it is only necessary to make the rotation axis of the component coincide with the rotation axis of the first guiding disk 210, so that each jaw assembly 300 can abut against the component, thereby realizing the gripping of the components of the cross-flow fan blade.

[0049] Refer to Figure 3 and Figure 4 As shown, the rotary gripping device further includes a fixed shaft 500. The first driving assembly 100 includes a first driving member 110 and a connecting member 120. The connecting member 120 is arranged at an interval from the fixed shaft 500, and both the connecting member 120 and the fixed shaft 500 extend along a preset direction. The first guiding disk 210 is sleeved on the fixed shaft 500 and rotates around the fixed shaft 500. One end of the connecting member 120 is drivingly connected to the first driving member 110, and the first driving member 110 drives the connecting member 120 to move perpendicular to the preset direction. The other end of the connecting member 120 is fixedly connected to the first guiding disk 210.

[0050] Specifically, the plurality of first guiding holes 211 are arranged at intervals around the fixed shaft 500.

[0051] In this embodiment, since one end of the connecting member 120 is drivingly connected to the first driving member 110, and the first driving member 110 drives the connecting member 120 to move perpendicular to the preset direction, and the other end of the connecting member 120 is fixedly connected to the first guiding disk 210, when the first driving member 110 drives the connecting member 120 to move perpendicular to the preset direction, the connecting member 120 can drive the first guiding disk 210 to rotate around the fixed shaft 500, so that the first guiding disk 210 can drive the plurality of first guiding holes 211 to rotate around the fixed shaft 500 simultaneously, so that the plurality of first guiding holes 211 drive the plurality of jaw assemblies 300 to approach or move away from each other, realizing the gripping or loosening of the components.

[0052] Refer to Figure 5 As shown, the first driving member 110 is a cylinder, and the piston rod of the cylinder is arranged parallel to the radial direction of the first guiding disk 210.

[0053] In this embodiment, since the piston rod of the cylinder is arranged parallel to the radial direction of the first guide disk 210, when the piston rod of the cylinder extends and retracts, the connecting member 120 can move in a direction perpendicular to the preset direction, so that the connecting member 120 drives the first guide disk 210 to rotate around the fixed shaft 500. Further, the first guide disk 210 can drive a plurality of first guide holes 211 to rotate around the fixed shaft 500 simultaneously, so that the plurality of first guide holes 211 can drive the plurality of jaw assemblies 300 to approach or move away from each other, thereby realizing the function of grasping or releasing parts.

[0054] Referring to Figure 4 , Figure 5 and Figure 6 As shown, each jaw assembly 300 includes a first guide member and a jaw 320. The first guide member extends along the preset direction. One end of the first guide member along the preset direction is fixedly connected to the jaw 320. The other end of the first guide member along the preset direction is inserted into a first guide hole 211 and contacts the hole wall of the first guide hole 211.

[0055] In this embodiment, since one end of the first guide member along the preset direction is fixedly connected to the jaw 320, and the other end of the first guide member along the preset direction is inserted into a first guide hole 211 and contacts the hole wall of the first guide hole 211, when the first guide hole 211 rotates around the preset direction, the first guide member inserted into the first guide hole 211 can move toward the middle of the first guide disk 210 or toward the edge of the first guide disk 210, so that the first guide member can drive the jaw 320 to move toward the middle of the first guide disk 210 or toward the edge of the first guide disk 210, thereby enabling the plurality of jaws 320 to approach or move away from each other, so as to clamp or release parts by the plurality of jaws 320.

[0056] Continuing to refer to Figure 4 , Figure 5 and Figure 6 As shown, the guide assembly 200 further includes a second guide disk 220. The second guide disk 220 is coaxially arranged with the first guide disk 210, and the first guide disk 210 rotates around the preset direction relative to the second guide disk 220. The second guide disk 220 is provided with a plurality of second guide holes 221 spaced apart along the preset direction. Each second guide hole 221 communicates with a first guide hole 211 and is located on one side of the first guide hole 211 along the preset direction. The first guide member is inserted into the second guide hole 221 and the first guide hole 211 at the same time. The jaw 320 is arranged on the side of the second guide disk 220 away from the first guide disk 210 along the preset direction;

[0057] Wherein, each second guide hole 221 extends along the radial direction of the second guide disk 220.

[0058] Specifically, each second guiding hole 221 is a strip-shaped guiding hole.

[0059] Specifically, the second guiding disc 220 is fixedly connected to the fixed shaft 500.

[0060] In this embodiment, since each first guiding member passes through a second guiding hole 221 and a first guiding hole 211 communicating with the second guiding hole 221 at the same time, and the first guiding disc 210 rotates relative to the second guiding disc 220 in a preset direction. Therefore, when the first guiding disc 210 rotates relative to the second guiding disc 220 in the preset direction, the first guiding hole 211 can drive the first guiding member to move towards the middle of the first guiding disc 210 or towards the edge of the first guiding disc 210. During the movement of the first guiding member, the second guiding hole 221 can make the first guiding member move along the radial direction of the first guiding disc 210, so that the first guiding member drives the jaw 320 connected thereto to move along the radial direction of the first guiding disc 210. In this way, a plurality of jaws 320 can be made to move away from or close to the central axis of the first guiding disc 210 along the radial direction of the first guiding disc 210 at the same time. During this process, as long as the central axis of the component is made to coincide with the central axis of the fixed shaft 500, each jaw 320 can be made to abut against the surface of the component, so as to realize the grasping function of the component.

[0061] Refer to Figure 6 As shown, each jaw 320 has a clamping portion 321 and a connecting portion 322 connected to the clamping portion 321. The clamping portion 321 and the connecting portion 322 are connected at one end along the radial direction of the first guiding disc 210 close to the edge of the first guiding disc 210. The first guiding member is connected to the connecting portion 322 at one end along the radial direction of the first guiding disc 210 close to the middle of the first guiding disc 210. And the clamping portion 321 is located on the side away from the first guiding disc 210 along the preset direction of the connecting portion 322, and the first guiding member is located on the side close to the first guiding disc 210 along the preset direction of the connecting portion 322.

[0062] In this embodiment, the first guide member can be connected to the clamping portion 321 through the connecting portion 322. When multiple first guide members approach each other radially along the first guide disk 210, multiple clamping portions 321 can be made to approach each other radially along the first guide disk 210, so that a component can be clamped between the multiple clamping portions 321. When multiple first guide members move away from each other radially along the first guide disk 210, multiple clamping portions 321 can be made to move away from each other radially along the first guide disk 210, so that the component can be released by the multiple clamping portions 321. At the same time, when the distance between the first guide member and the center of the first guide disk 210 changes, the space between the multiple clamping portions 321 can be changed. In this way, the purpose of clamping components of different sizes can be achieved by changing the distance between the first guide member and the center of the first guide disk 210.

[0063] Referring to Figure 1 and Figure 2 As shown, an avoidance hole 230 is provided at one end of the guide assembly 200 close to the jaw assembly 300 along a preset direction, and the avoidance hole 230 is coaxially arranged with the first guide disk 210.

[0064] In this embodiment, when the jaw assembly 300 clamps a component, the avoidance hole 230 can provide an avoidance space for the component to avoid interference of the guide assembly 200 with the component.

[0065] Specifically, in this embodiment, the avoidance hole 230 is cylindrical, and the aperture of the avoidance hole 230 is larger than the diameter of the cross-flow fan blade component, so that the cross-flow fan blade component can be accommodated in the avoidance hole 230.

[0066] Referring to Figure 2 , Figure 3 and Figure 4 As shown, the second driving assembly 400 includes a transmission member 410, a driving member 420, a second driving member 430 and a driven member 440. The driven member 440 is coaxially arranged with the first guide disk 210, and at least part of the guide assembly 200 is fixedly connected to at least part of the driven member 440. The driving member 420 and the driven member 440 are parallel and spaced apart, and both the driving member 420 and the driven member 440 are drivingly connected to the transmission member 410. The second driving member 430 is drivingly connected to the driving member 420 and drives the driving member 420 to rotate around a preset direction.

[0067] Specifically, the driven member 440 is fixedly connected to the fixed shaft 500, and the driven member 440 is fixedly connected to the edge of the second guide disk 220.

[0068] Specifically, in this embodiment, the driving member 420 is a driving pulley, the driven member 440 is a driven pulley, and the transmission member 410 is a timing belt.

[0069] Specifically, the above-mentioned rotary clamping device further includes a guide shaft 600. The guide shaft 600 is coaxially arranged with the fixed shaft 500, and the fixed shaft 500 is sleeved on the guide shaft 600 so that the guide assembly 200 can rotate around the guide shaft 600.

[0070] In this embodiment, when the second driving member 430 drives the driving member 420 to rotate in a preset direction, the driving member 420 can drive the driven member 440 to rotate in the preset direction through the transmission member 410, so that the driven member 440 drives the guide assembly 200 to rotate in the preset direction, and the guide assembly 200 drives the jaw assembly 300 to rotate, thereby realizing the rotation of the component.
