[0029] Please see Figures 1-5 As shown, this application provides a rotatable positioning gripper device, which includes a base 100, a mounting base 110, a motor 120, and a rotating assembly.
[0030] The base 100 includes at least one first side plate 101; the mounting base 110 includes a connecting plate 111 extending in a first direction and at least one second side plate 112 extending in a second direction, the second side plate 112 being rotatably connected to the first side plate 101; a motor 120 is connected to the connecting plate 111, the output end of the motor 120 is disposed through the connecting plate 111, and the output end of the motor 120 is connected to a gripper assembly 130; a rotating assembly is disposed on the side of the side plate away from the motor 120 in the first direction, the rotating assembly including a first friction disk 140 and a second friction disk 150, the second friction disk 150 being detachably connected to the side of the first side plate 101 facing away from the second side plate 112, the first friction disk 140 being connected to the side of the second friction disk 150 facing away from the first side plate 101, at least a portion of the first friction disk 140 also passing through the second friction disk 150 and the first side plate 101 and being fixedly connected to the second side plate 112.
[0031] The base 100 also includes a base plate 102, and a first side plate 101 is connected to the base plate 102 and is perpendicular to the base plate 102. This provides support.
[0032] In one specific embodiment, the second friction disc 150 has a connecting post 200 on the side facing the first side plate 101, and the first side plate 101 has a connecting hole 210 on the side facing the second friction disc 150. The second friction disc 150 and the first side plate 101 are assembled by inserting the connecting post 200 into the connecting hole 210. The connecting post 200 and the connecting hole 210 enable a detachable connection between the second friction disc 150 and the first side plate 101.
[0033] The rotatable positioning gripper device in this embodiment uses a first friction disk 140 and a second friction disk 150 to stably mount the motor 120 and the mounting base 110 onto the first side wall of the base 100. When it is necessary to rotate the motor 120 to adjust the orientation of the motor 120 output end, the second friction disk 150 is separated from the first side plate 101, allowing the second friction disk 150 to drive the first friction disk 140 to rotate, thereby causing the first friction disk 140 to drive the motor 120 to rotate for adjustment. When it is necessary to fix the orientation of the motor 120, the second friction disk 150 is reconnected to the first side plate 101. The friction between the second friction disk 150 and the first friction disk 140 makes it difficult for the first friction disk 140 and the second friction disk 150 to rotate relative to each other, thereby fixing the first friction disk 140 in position and thus fixing the motor 120. The rotatable positioning gripper device in this embodiment has a simple overall structure and is easy to adjust.
[0034] In one specific embodiment, the first friction disc 140 includes a connecting portion 141 and a plug-in portion 142. The plug-in portion 142 passes through the second friction disc 150 and the first side plate 101 and is plugged into the second side plate 112. The connecting portion 141 is connected to one side of the second friction disc 150. The plug-in portion 142 connects to the second side plate 112, allowing the first friction disc 140 to drive the mounting base 110 to rotate, thereby causing the motor 120 to rotate when the first friction disc 140 rotates.
[0035] The second side plate 112 has a plug-in groove 143 facing the plug-in portion 142. The plug-in groove 143 has a prismatic groove structure. In a specific example, the plug-in portion 142 has a square structure, and the plug-in groove 143 has a square structure corresponding to the plug-in portion 142. Of course, the plug-in portion 142 and the plug-in groove 143 can also be pentagonal, hexagonal, or other polygonal structures.
[0036] In one specific implementation, the rotating assembly includes a connector 160, which extends along a first direction to connect the first friction disc 140 and the second side plate 112. The connector 160 can be a screw, which securely connects the first friction disc 140 and the second side plate 112, thereby connecting them in the first direction. Alternatively, the connector 160 can also be a screw or other connecting component.
[0037] In one specific embodiment, the insertion part 142 has an assembly groove on the side facing the second side plate 112. At least a portion of the connector 160 is located in the assembly groove, and an elastic member 170 is provided in the assembly groove. The two ends of the elastic member 170 abut against the assembly groove and the insertion groove 143. The distance between the second side plate 112 and the first friction disc 140 in the connected state can be adjusted by rotating the connector 160. After rotating the connector 160 to increase the distance between them, the elastic member 170 releases pressure, pushing the first friction disc 140 and the second friction disc 150 to separate from the first side plate 101. After the second friction disc 150 is disengaged from the first side plate 101, the first friction disc 140 and the second friction disc 150 can rotate relative to each other based on the first side plate 101, thereby driving the mounting base 110 and the motor 120 to rotate based on the first side plate 101, adjusting the orientation of the output end of the motor 120.
[0038] The elastic element 170 includes a retaining spring, or other devices with elastic deformation capabilities.
[0039] In one specific implementation, at least two abutment walls 180 are provided on the side of either the first friction disk 140 or the second friction disk 150 facing the other. Abutment grooves 190 are provided on both sides of the abutment wall 180. The first friction disk 140 and the second friction disk 150 are fitted together via the friction walls. The friction between the first friction disk 140 and the second friction disk 150 reduces or prevents relative rotation between them.
[0040] As a specific example, the abutment wall 180 can be an annular structure, with the centers of the abutment wall 180, the first friction disk 140, and the second friction disk 150 located on the same rotation axis, which extends along a first direction. Alternatively, the centers of the first friction disk 140 and the second friction disk 150 can be located on the same rotation axis, which extends along the first direction, and the abutment wall 180 can extend on the first friction disk 140 and the second friction disk 150 in a direction perpendicular to the rotation axis.
[0041] In summary, the rotatable positioning gripper device provided in this application has the advantages of simple structure and easy adjustment.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
