[0005] After the present invention adopts the above structure, it can realize circumferential and automatic polishing of the wire, thereby improving the polishing efficiency of the wire, having good polishing consistency for the wire groove, and reducing the labor cost.

[0006] In a possible implementation manner, the driving assembly includes a driving motor, a driving pulley, a transmission belt, and a driven pulley; the driving motor is fixed inside the frame, the driving pulley is fixed on the output shaft of the driving motor, the driven pulley is coaxially sleeved and fixed outside the driving shaft, and the driven pulley is in transmission connection with the driving pulley through the transmission belt; after adopting this structure, when the driving motor drives the driving pulley to rotate, the driving pulley can drive the driven pulley to rotate through the transmission belt. At this time, the driven pulley can drive the driving shaft to rotate, that is, the driving shaft can drive the turntable to rotate, so that the driving assembly can reliably drive the turntable to rotate relative to the frame.

[0007] In a possible implementation, a wire guide is fixed to the inner side of one end of the drive shaft facing the turntable, and the wire is movably threaded through the wire guide; after adopting this structure, under the action of the wire guide, the wire guide can guide the wire so that the wire can smoothly pass through the drive shaft.

[0008] In a possible implementation, each polishing unit includes a driving shaft, a driven shaft and a sand belt; the driven shaft is connected to the outer end face of the turntable, the driving shaft is axially inserted into the turntable and rotatably connected to the turntable, the sand belt is sleeved on the outer ends of the driven shaft and the driving shaft, the inner side edge of the sand belt abuts tightly against the outer wall of the wire, a moving gear is coaxially fixed to the inner end of the driving shaft, a fixed gear coaxially arranged with the drive shaft is fixed on the machine frame, and the moving gear meshes with the fixed gear; after adopting this polishing unit, in the process of the drive assembly driving the drive shaft to rotate so that the drive shaft drives the turntable to rotate, under the action of the planetary gear structure formed by the moving gear and the fixed gear, the driving shaft can be rotated, so that the sand belt can be rotated, that is, in the state of the turntable rotating, combined with the rotation of the sand belt, the circumferential polishing of the outer surface of the wire can be realized.

[0009] In a possible implementation, each polishing unit further includes a support shaft, a first swing arm, a second swing arm and a tension spring; the support shaft is axially inserted into the turntable and rotatably connected to the turntable, one end of the first swing arm is fixed to the outer end of the support shaft, the inner end of the driven shaft is rotatably connected to the other end of the first swing arm, one end of the second swing arm is fixed to the inner end of the support shaft, and both ends of the tension spring are respectively fixed to one end of the second swing arm and the inner end face of the turntable; the tension spring is used to apply a first rotational force to the support shaft to tension the sand belt by the driven shaft and the driving shaft, and make the inner side edge of the sand belt abut tightly against the outer wall of the wire; after adopting this structure, under the action of the tension spring, the tension spring can apply a first rotational force to the support shaft to tension the sand belt by the driven shaft and the driving shaft.

Since the direction of the second rotational force is opposite to the direction of the first rotational force, the pressing force between the inner side edge of the abrasive belt and the wire can be weakened, and further the polishing strength of the abrasive belt on the wire can be weakened. On the contrary, when the adjusting bolt is rotated and gradually releases the pushing state on the third swing arm, under the action of the tension spring, the pressing force between the inner side edge of the abrasive belt and the wire can be increased, and further the polishing strength of the abrasive belt on the wire can be improved; that is, through the above structure, the polishing strength of the abrasive belt on the wire can be adjusted.

[0011] In a possible implementation manner, the abrasive belts in the two polishing units are distributed in a staggered manner along the axial direction of the wire; after adopting this structure, when the two polishing units perform circumferential polishing on the wire, the situation that the abrasive belts in the two polishing units interfere with each other can be avoided.

[0016] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] See Figures 1-3 As shown, the embodiments of the present application disclose a wire polishing device, including a frame 1, a driving assembly, a turntable 2, a hollow driving shaft 3, and two polishing units 4; the driving assembly is fixed inside the frame 1, the driving shaft 3 is rotatably connected to the frame 1, the turntable 2 is rotatably connected to the side wall of the frame 1, one end of the driving shaft 3 coaxially penetrates through the turntable 2 and is fixed to the turntable 2, the driving shaft 3 is used for the wire 5 to axially pass through, the driving shaft 3 is in transmission connection with the driving assembly, the two polishing units 4 are symmetrically connected to the outer end surface of the turntable 2, the two polishing units 4 are located on both sides in the radial direction of the wire 5, and the driving assembly is used to drive the driving shaft 3 and the turntable 2 to rotate relative to the wire 5 so that the two polishing units 4 perform circumferential polishing on the wire 5.

[0018] The driving assembly includes a driving motor, a driving pulley, a transmission belt 61, and a driven pulley 62; the driving motor is fixed inside the frame 1, the driving pulley is fixed to the output shaft of the driving motor, the driven pulley 62 is coaxially sleeved and fixed outside the driving shaft 3, and the driven pulley 62 is in transmission connection with the driving pulley through the transmission belt 61; after adopting this structure, when the driving motor drives the driving pulley to rotate, the driving pulley can drive the driven pulley to rotate through the transmission belt. At this time, the driven pulley can drive the driving shaft to rotate, that is, the driving shaft can drive the turntable to rotate, so that the driving assembly can reliably drive the turntable to rotate relative to the frame.

[0019] On the inner side of one end of the drive shaft 3 facing the turntable 2, a wire guide 31 is fixed, and the wire 5 is movably threaded through the wire guide 31. After adopting this structure, under the action of the wire guide, the wire guide can play a guiding role on the wire, so that the wire can smoothly pass through the drive shaft.

[0020] Each polishing unit 4 includes a driving shaft 41, a driven shaft 42 and a sand belt 43. The driven shaft 42 is connected to the outer end face of the turntable 2. The driving shaft 41 is axially inserted into the turntable 2 and rotatably connected to the turntable 2. The sand belt 43 is sleeved on the outer ends of the driven shaft 42 and the driving shaft 41. The inner side edge of the sand belt 43 abuts tightly against the outer wall of the wire 5. A moving gear 44 is coaxially fixed on the inner end of the driving shaft 41. A fixed gear 7 coaxially arranged with the drive shaft 3 is fixed on the frame 1. The moving gear 44 meshes with the fixed gear 7. After adopting this polishing unit, during the process that the drive assembly drives the drive shaft to rotate so that the drive shaft drives the turntable to rotate, under the action of the planetary gear structure formed by the moving gear and the fixed gear, the driving shaft can be rotated, so that the sand belt can be rotated. That is, in the state where the turntable rotates, with the rotation of the sand belt, the circumferential polishing of the outer surface of the wire can be realized.

[0021] Each polishing unit 4 also includes a support shaft 45, a first swing arm 46, a second swing arm 47 and a tension spring 48. The support shaft 45 is axially inserted into the turntable 2 and rotatably connected to the turntable 2. One end of the first swing arm 46 is fixed to the outer end of the support shaft 45. The inner end of the driven shaft 42 is rotatably connected to the other end of the first swing arm 46. One end of the second swing arm 47 is fixed to the inner end of the support shaft 45. The two ends of the tension spring 48 are respectively fixed to one end of the second swing arm 47 and the inner end face of the turntable 2. The tension spring 48 is used to apply a first rotational force to the support shaft 45 to tension the sand belt 43 by the driven shaft 42 and the driving shaft 41, and make the inner side edge of the sand belt 43 abut tightly against the outer wall of the wire 5. After adopting this structure, under the action of the tension spring, the tension spring can apply a first rotational force to the support shaft to tension the sand belt by the driven shaft and the driving shaft. At the same time, after the sand belt is tensioned, the inner side edge of the sand belt can be made to abut tightly against the outer wall of the wire, so that when the sand belt rotates, the sand belt can reliably perform circumferential polishing on the wire.

[0022] Each polishing unit 4 also includes an adjusting bolt 49; a support block 21 corresponding to each adjusting bolt 49 is fixed on the inner end surface of the turntable 2, and the screw portion of each adjusting bolt 49 is inserted into the support block 21 at the corresponding position and is threadedly connected to the support block 21; a third swing arm 451 is also provided on the side wall of the inner end portion of each support shaft 45, and the screw portion of each adjusting bolt 49 abuts against the third swing arm 451 at the corresponding position; when the adjusting bolt 49 is rotated so that the screw portion of the adjusting bolt 49 pushes the third swing arm 451, the third swing arm 451 is used to apply a second rotational force to the support shaft 45, and the direction of the second rotational force is the same as that of the first rotational force. The direction of the force is opposite; by adopting this structure, when the adjusting bolt is rotated, such as when the screw portion of the adjusting bolt pushes the third swing arm, the third swing arm can apply a second rotational force to the supporting shaft. Since the direction of the second rotational force is opposite to the direction of the first rotational force, the pressing force between the inner side edge of the sand belt and the wire can be weakened, thereby weakening the polishing strength of the sand belt on the wire. Conversely, when the adjusting bolt is rotated and the pushing state of the third swing arm is gradually released, under the action of the tension spring, the pressing force between the inner side edge of the sand belt and the wire can be increased, thereby increasing the polishing strength of the sand belt on the wire. That is, through the above structure, the polishing strength of the sand belt on the wire can be adjusted.

[0023] The abrasive belts 43 in the two polishing units 4 are staggeredly distributed along the axial direction of the wire 5; by adopting this structure, when the two polishing units perform circumferential polishing on the wire, mutual interference of the abrasive belts in the two polishing units can be avoided.

[0024] When the present invention is working, the wire is pulled by the pulling device located in the post-process of the polishing device, that is, the wire can continuously pass through the driving shaft; when the driving assembly drives the driving shaft to rotate so that the driving shaft drives the turntable to rotate, under the action of the planetary gear structure formed by the moving gear and the fixed gear, the driving shaft can be rotated, so that the abrasive belt can be rotated, that is, when the turntable rotates relative to the wire, the outer surface of the wire can be polished circumferentially in coordination with the rotation of the abrasive belt.

[0025] The above 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 that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
