Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a stranding mechanism. Background Technology

[0002] Many existing wire harnesses require twisting to compress space and facilitate wiring. Current twisting methods are mainly done manually or partially automatically. Manual twisting is relatively expensive, while automatic twisting requires clamping and rotating the wires. Current designs can only twist two wires at a time, resulting in relatively low twisting efficiency. Therefore, a twisting mechanism that can twist multiple wires simultaneously, improving efficiency, and with a simple structure is needed. Utility Model Content

[0003] The main objective of this invention is to provide a stranding mechanism that can simultaneously strand multiple wires, improve stranding efficiency, and has a simple structure.

[0004] This utility model proposes a stranding mechanism, including a base, at least one wire clamping mechanism, and a rotation drive device;

[0005] The wire clamp mechanism includes a clamping head, an outer rotating rod, an inner clamping rod, a rotating connector, a pushing connector, and a horizontal driving mechanism.

[0006] The gripping head includes an upper gripping component and a lower gripping component. The middle sections of the upper gripping component and the lower gripping component are rotatably connected to the front side of the outer rotating rod. The inner gripping rod is disposed inside the outer rotating rod, and the front side of the inner gripping rod is connected to the rear side of the upper gripping component and the lower gripping component. The rear side of the inner gripping rod is connected to the horizontal driving mechanism through the pushing connector. The horizontal driving mechanism drives the gripping head to grip or release the wire by pushing the inner gripping rod to move back and forth. The rotating connector is disposed at the end of the outer rotating rod and is fixedly connected to the outer rotating rod.

[0007] The rotation drive device includes a rotation motor, a transmission wheel, and a transmission belt. The output shaft of the rotation motor is fixedly connected to the transmission wheel. The transmission wheel is connected to the rotation connector via the transmission belt. After the clamping head clamps at least two wires, the rotation motor drives the clamping head to rotate via the rotation connector, thereby realizing the function of stranding wires.

[0008] Preferably, the horizontal drive mechanism may be a drive cylinder or a drive motor.

[0009] Preferably, the base further includes a first connecting seat, which is disposed at the bottom of the base. The first connecting seat has a through connecting hole, and the outer rotating rod is rotatably connected to the first connecting seat connecting hole.

[0010] Preferably, a first connecting seat connecting groove is provided on the inner side surface of both ends of the connecting hole of the first connecting seat, and a first connecting bearing is provided between the outer rotating rod and the first connecting seat connecting groove.

[0011] Preferably, the base further includes a second connecting seat, which is disposed at the bottom of the base, and the push connector is slidably connected to the second connecting seat.

[0012] Preferably, a push connector connecting groove is provided on the front side of the push connector, and the rear side of the inner clamping rod is disposed in the push connector connecting groove.

[0013] Preferably, a rotating groove for the push connector is provided on the inner side of the connecting groove of the push connector, and a second connecting bearing is provided on the outer side of the rear side of the inner clamping rod, the second connecting bearing being disposed in the rotating groove of the push connector.

[0014] Preferably, the rotation drive device further includes an auxiliary wheel, which is disposed between the rotating connecting members of adjacent clamp mechanisms. The transmission belt is disposed between the auxiliary wheel and the rotating connecting member. The auxiliary wheel enables the transmission belt to be close to the rotating connecting member, thereby making the rotation motor drive the multiple rotating connecting members to rotate more smoothly.

[0015] The beneficial effects of the stranding mechanism of this utility model are as follows:

[0016] By setting up a wire clamping mechanism and a rotation drive device, the wire can be rotated while being clamped, thereby completing the stranding process.

[0017] A single rotating motor can drive multiple wire clamp mechanisms to rotate, thereby improving the efficiency of stranding.

[0018] By setting auxiliary wheels, the transmission belt can be brought closer to the rotating connecting parts, which makes it smoother when the rotating motor drives multiple rotating connecting parts to rotate.

[0019] Each wire clamp mechanism is driven by a separate horizontal drive mechanism. In this patent, the horizontal drive mechanism is a drive cylinder, which enables higher stability. Attached Figure Description

[0026] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] Reference Figures 1 to 4 An embodiment of the stranding mechanism of this utility model is proposed:

[0028] A stranding mechanism includes a base 1, three wire clamping mechanisms 3, and a rotation drive device 2.

[0029] The base 1 includes a base body 11, a first connecting seat 12, a second connecting seat 13, and a third connecting seat 14. The first connecting seat 12 and the second connecting seat 13 are respectively disposed at the bottom of the base body 11 and fixedly connected to the base body 11. The third connecting seat 14 is disposed at the bottom of the first connecting seat 12 and fixedly connected to the first connecting seat 12. The first connecting seat 12 has a through connecting hole, and connecting grooves are provided on the inner sides of both ends of the connecting hole. The second connecting seat 13 has a connecting groove on its top.

[0030] The wire clamp mechanism 3 includes a clamping head 31, an outer rotating rod 32, an inner clamping rod 33, a rotating connector 35, a pushing connector 34, and a horizontal drive mechanism 39. The clamping head 31 includes an upper clamping member 311 and a lower clamping member 312, the middle sections of which are rotatably connected to the front side of the outer rotating rod 32. The outer rotating rod 32 is rotatably connected within the connecting hole of the first connecting seat. A first connecting bearing is provided between the outer rotating rod 32 and the connecting groove of the first connecting seat. The rotating connector 35 is located at the end of the outer rotating rod 32 and is fixedly connected to it.

[0031] The inner clamping rod 33 is located inside the outer rotating rod 32, and its front side is connected to the rear side of the upper clamping member 311 and the lower clamping member 312 via connecting rods 38. The push connecting member 34 is slidably connected and located in the connecting groove of the second connecting seat. The front side of the push connecting member 34 is provided with a push connecting member connecting groove 341, and the rear side of the inner clamping rod 33 is located in the push connecting member connecting groove 341. The outer side of the rear side of the inner clamping rod 33 is provided with a second connecting bearing, which is located in the rotating groove 342 of the push connecting member. The rear side of the inner clamping rod 33 is connected to the horizontal drive mechanism via the push connecting member 34. The horizontal drive mechanism 39 drives the clamping head 31 to clamp or release the wire by pushing the inner clamping rod 33 to move back and forth. The horizontal drive mechanism 39 can be a drive cylinder or a drive motor; in this embodiment, it is a drive cylinder.

[0032] The rotation drive device 2 includes a rotation motor 21, an auxiliary wheel 24, a transmission wheel 22, and a transmission belt 23. The output shaft of the rotation motor 21 is fixedly connected to the transmission wheel 22. The transmission wheel 22 is connected to the rotating connector 35 via the transmission belt 23. The auxiliary wheel 24 is rotatably connected to the third connecting seat 14 and is located at the bottom between the rotating connectors 35 of adjacent clamp mechanisms 3. The top of the transmission belt 23 is wound around the transmission wheel 22, and the bottom is wound between the auxiliary wheel 24 and the rotating connector 35. The auxiliary wheel 24 allows the transmission belt 23 to be close to the rotating connector 35, thereby enabling the rotation motor 21 to drive the multiple rotating connectors 35 to rotate more smoothly.

[0033] In use, the horizontal drive mechanism 39 drives the inner clamping rod 33 to move backward, thereby opening the clamping head 31. After two adjacent wires are placed inside the clamping head 31, the horizontal drive mechanism 39 drives the inner clamping rod 33 to move backward, thereby clamping the wires through the clamping head 31. After clamping the wires, the rotating motor 21 drives the rotating connecting piece 35 to rotate via the transmission belt 23, thereby driving the clamping head 31 to rotate. At this time, since the other end of the wire is limited and fixed by another mechanism, the two wires are driven to complete the winding process.
