[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 8 As shown, a transfer device for bearing ring processing of the present invention comprises: a control box 10, a rotating frame, the rotating frame is rotatably arranged inside the control box 10, and also comprises: a winding device, a lifting rope 30, a hook 32, a top plate 40 and an expansion mechanism, the winding device is arranged on the rotating frame, a plurality of lifting ropes 30 are arranged on the rotating frame with spacer rings, and the bottom ends of the lifting ropes 30 are close to each other, so that the plurality of lifting ropes 30 are arranged in an inverted cone shape, the hook 32 is arranged below the lifting rope 30, the hook 32 is used to clamp the bearing ring, the top plate 40 is arranged directly below the rotating frame, and the plurality of lifting ropes 30 all pass through the top plate 40, the top plate 40 is connected to the rotating frame by a top extension structure, so that the top plate 40 can move downward to expand the lifting ropes 30 outward, the expansion mechanism is arranged on the bottom wall of the top plate 40, and the expansion mechanism can shrink or expand along the radial direction of the top plate 40 when the top plate 40 moves up and down, so that the torsional force above the lifting rope 30 can be quickly transmitted to the bottom.

[0032] When the bearing ring is transported in the workshop, the hook 32 clamps the bearing ring and drives the winding device to wind up the lifting rope 30 to raise the bearing ring for subsequent transportation. When it is transported to the placement position and the placement direction of the bearing ring needs to be adjusted, the rotation of the rotating frame drives the top of the lifting rope 30 to twist. At the same time, the rotation of the rotating frame causes the extension structure to push the top plate 40 to move downward, so that the outer peripheral surface of the top plate 40 expands and supports the conically arranged lifting rope 30. When the top plate 40 moves downward, the expansion mechanism expands and supports outward along the radial direction of the top plate 40, thereby tightening the lifting rope 30 to improve the transmission of the torsional force on the lifting rope 30. At the same time, the top plate 40 continues to move downward so that the torsional force above the lifting rope 30 is quickly transmitted downward. When the bearing ring is twisted to the angle that needs to be adjusted, the top plate 40 and the expansion mechanism can eliminate the inertia of the bearing ring after the twisting, thereby improving the efficiency of adjusting the placement direction of the bearing ring during transportation, reducing the economic cost of production, and avoiding manual adjustment of the direction under the bearing ring, thereby improving the safety of the device.

[0033] like Figures 2 to 4 As shown, sliding bars 11 are arranged on both sides of the control box 10, and the sliding bars 11 can cooperate with the slide rails in the workshop so that the control box 10 can move along the slide rails. A top cover 12 is arranged on the top of the control box 10, and a driving component is arranged on the top cover 12. The driving component can drive the rotating frame to rotate, so that the rotation of the rotating frame can adjust the placement direction of the bearing ring hoisted below, and a round hole is arranged on the top cover 12, and the driving motor 21 is located in the round hole, so that the driving motor 21 can rotate in the round hole. To avoid interference of the top cover 12 with the driving motor 21, the rotating frame is composed of a lower disc 25 and an upper disc 26, and a fixing rod 24 is fixedly arranged between the lower disc 25 and the upper disc 26, and teeth 22 are arranged on the outer peripheral surface of the upper disc 26. The driving component includes: a motor 13 and a driving gear 15. The motor 13 is fixedly arranged on the top of the top cover 12, and a rotating rod 14 is arranged at the output end of the motor 13. The driving gear 15 is arranged at one end of the rotating rod 14, and the driving gear 15 is meshed with the teeth 22.

[0034] Therefore, when the rotating frame controls the adjustment of the placement direction of the bearing ring, the motor 13 can drive the rotating rod 14 to rotate, and the rotation of the rotating rod 14 drives the driving gear 15 to rotate. Since the driving gear 15 is meshed with the teeth 22, the rotation of the driving gear 15 drives the upper disc 26 to rotate. The upper disc 26 is connected to the lower disc 25 through the fixed rod 24. Therefore, the rotation of the upper disc 26 drives the lower disc 25 to rotate. Since the winding device and the lifting rope 30 are both arranged on the rotating frame, the rotation of the rotating frame can drive the bearing ring hoisted below to rotate, thereby completing the adjustment of the placement direction of the bearing ring.

[0035] like Figures 3 to 5As shown, the winding device includes: a winding rod 50, a winding disc 51, a first guide wheel 52, a second guide wheel 53, a third guide wheel 54 and a fourth guide wheel 55. The winding rod 50 is rotatably arranged on the top of the lower disc 25. A plurality of winding discs 51 are sequentially arranged on the outer circumferential surface of the winding rod 50 along the axial direction, and there are four winding discs 51. The winding discs 51 are used to wind up the suspension rope 30. The first guide wheel 52, the second guide wheel 53, the third guide wheel 54 and the fourth guide wheel 55 are circumferentially spaced at intervals on the top of the lower disc 25, and the first guide wheel 52, the second guide wheel 53, the third guide wheel 54 and the fourth guide wheel 55 are circumferentially spaced at intervals. 53, the third guide wheel 54 and the fourth guide wheel 55 are distributed at ninety degrees in sequence, and the first guide wheel 52, the second guide wheel 53, the third guide wheel 54 and the fourth guide wheel 55 correspond to the winding disk 51 one by one, and sliding grooves 56 are circumferentially spaced on the lower disk 25, and any adjacent sliding grooves 56 are distributed at ninety degrees. The sling rope 30 can pass through the sliding grooves 56 so that the sling rope 30 is distributed in a cone shape to avoid interference of the lower disk 25 with the sling rope 30. A driving motor 21 is arranged on the upper disk 26, and the output end of the driving motor 21 is transmission-connected to the winding rod 50.

[0036] When the sling rope 30 is wound up, the driving motor 21 can drive the winding rod 50 to rotate, and the rotation of the winding rod 50 drives the winding disk 51 to rotate, and the winding disk 51 rotates to wind up the sling rope 30. The four guide wheels play a guiding role in winding up the sling rope 30, making the winding more stable, thereby improving the stability of the bearing ring during transportation.

[0037] like Figures 5 to 8 As shown, the extension structure includes: an extension rod 60, the extension rod 60 is arranged at the bottom of the lower disc 25, and the top plate 40 is connected to the bottom end of the extension rod 60, a plurality of limit grooves 41 are opened on the top plate 40, and the plurality of limit grooves 41 are opened along the circumference of the top plate 40, each limit groove 41 corresponds to a suspension rope 30, and the suspension ropes 30 all pass through the limit grooves 41, a connecting plate is fixedly arranged below the top plate 40, and the diameter length of the connecting plate is consistent with that of the top plate 40, and the connection between the connecting plate and the top plate 40 is consistent with that of the top plate 40. The connecting plates are fixedly connected by connecting columns, and a guide groove 42 is opened circumferentially on the connecting plate. The guide groove 42 is opened so that the expansion mechanism can push the suspension rope 30 outward when expanding the suspension rope 30, and the expansion mechanism is arranged between the connecting plate and the top plate 40. The expansion mechanism can expand the four suspension ropes 30 outward along the radial direction of the top plate 40, so that the torsional force above the suspension rope 30 is quickly transmitted to the bottom, thereby improving the direction adjustment speed of the bearing ring and improving the transportation efficiency of the bearing ring.

[0038] like Figures 5 to 8As shown, the expansion mechanism includes: an arcuate guide groove 71, a gear 72, an expansion member 73 and a fixed plate 74, the fixed plate 74 is fixedly arranged on the connecting plate, the expansion member 73 is slidably arranged on the fixed plate 74, a rotating gear 70 is arranged on the top of the fixed plate 74, the arcuate guide groove 71 is circumferentially opened on the rotating gear 70, and a sliding bar is arranged on the expansion member 73, and the sliding bar can cooperate with the arcuate guide groove 71 so that the rotating gear 70 rotates to drive the expansion member 73 to slide, the gear 72 is arranged on the top of the fixed plate 74, and the gear 72 is meshed with the rotating gear 70, a motor three is arranged between the connecting plate and the top plate 40, and the output end of the motor three is transmission connected with the gear 72.

[0039] When in use, motor three can drive gear 72 to rotate, and the rotation of gear 72 drives the rotating gear 70 to rotate, and the rotation of rotating gear 70 drives the expansion member 73 to expand outward, so that the expansion member 73 pushes the corresponding suspension rope 30, so that the suspension rope 30 is in a taut state. At the same time, when the expansion member 73 pushes the corresponding suspension rope 30, the bearing ring below can be moved upward, so that the expansion mechanism and the bearing ring are close, so that the expansion mechanism can better eliminate the inertia of the bearing ring's turning, so as to improve the stability of the bearing ring after turning, greatly shortening the time required for the bearing ring to be placed and turned, thereby improving production efficiency.
