[0002] In the manufacture of metal rings, the metal ring is generally bent from a bar or tubular workpiece, and the welding fixed connection position is ensured to be stable in structure, but a welding scar ring is formed. In order to make the surface of the metal ring smooth, the welding scar ring needs to be ground and polished. The existing grinding device includes a turnover frame mechanism and a grinding mechanism.

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] The metal ring welding scar grinding device comprises a turnover frame mechanism 10 and a grinding mechanism 40 assembled on a workbench. The turnover frame mechanism 10 comprises a pair of coaxial and symmetrical rotating seats 12, which are rotatably assembled on the workbench through bearing seats, and one rotating seat 12 is provided at one end with a servo motor 13 for driving the reciprocating rotation thereof. The rotating seat 12 is fixedly connected with a rotating frame 11 on one side, and the synchronous frame 14 is fixedly assembled between the two rotating frames 11.

[0038] The existing metal ring welding scar grinding device is provided with a plurality of clamping structures, usually clamps, for fixing the metal ring on the synchronous frame 14 and the rotating frame 11. These clamping structures fix and clamp the metal ring on one side of the synchronous frame 14, so that the central axis of the welding scar ring is coaxial with the rotating seat 12, so that the welding scar ring can reciprocatingly rotate with the central axis as the rotating axis, and the reciprocating rotation angle of the rotating seat 12 is between 180°-200°.

[0039] The grinding mechanism 40 is symmetrically distributed on both sides of the welding bead ring, including a sliding table module and a polishing belt assembly assembled on the movable table of the sliding table module. The sliding table module drives the grinding station of the polishing belt assembly to fit one side of the welding bead ring of the metal ring. By cooperating with the turnover frame mechanism 10, the grinding of the welding bead ring is completed to meet the surface finish requirement of the metal ring.

[0040] In order to realize the coaxial rotation of the welding bead ring and the rotating seat 12, a plurality of clamping structures on the turnover frame mechanism 10 are designed according to the model of the metal ring to ensure that the welding bead ring of the same type of metal ring can rotate along its own central axis within the working range of the grinding mechanism 40 and receive polishing.

[0041] When different types of metal rings need to be ground, the positions of the clamping structures on the turnover frame mechanism 10 must be adjusted to ensure that the welding bead ring can be fixed at the preset position (coaxial position with the rotating seat 12). In combination Figure 1 and Figure 10 Since the annular structure and cross-sectional diameter of different types of metal rings are different, when adjusting the position of the clamping structure, the position of the clamping structure needs to be adjusted one by one first, and then the metal ring is fixed by the clamping structure to determine the position of the welding bead ring. In actual operation, the position of the clamping structure often needs to be adjusted several times, and the rotation of the turnover frame mechanism 10 needs to be checked several times to accurately adjust the positions of the plurality of clamping structures and ensure that the welding bead ring is fixed at the preset position. This process not only increases the complexity of adjustment, but also brings great difficulty in adjustment accuracy and adjustment procedure.

[0042] In combination Figures 1 to 10 To solve the problems of great difficulty in initial adjustment of the clamping structure and difficulty in accurately fixing the welding bead ring at the preset position when polishing the same type of metal ring in the prior art, the present application provides a metal ring welding bead grinding device, which further comprises a lifting mechanism 20 and an auxiliary positioning mechanism 30.

[0043] Specifically, the lifting mechanism 20 comprises a movable plate 21 movably arranged on one side of the rotating frame 11, and a locking structure is arranged on one side of the movable plate 21 to fix the position of the movable plate 21 on the surface of the rotating frame 11. A first clamping wheel 22 for lifting the outer surface of the metal ring is assembled on the upper side of the movable plate 21, and a second clamping wheel 23 for abutting against the inner surface of the metal ring is connected to the upper side of the first clamping wheel 22 through a rotating plate 24. The first clamping wheel 22 and the second clamping wheel 23 are the same components, and the arc surfaces of the first clamping wheel 22 and the second clamping wheel 23 are both provided with annular V-shaped grooves above the rotating shaft of the rotating seat 12. When the two pairs of symmetrically arranged first clamping wheels 22 and second clamping wheels 23 cooperate to form a fixed clamping on the metal ring, the metal ring can be automatically clamped in the middle of the V-shaped groove and kept in a vertical state. Therefore, for metal rings with different radii and cross-sectional diameters, the metal ring can be adaptively fixed above the rotating shaft of the rotating seat 12 through the clamping and fixing of the two pairs of first clamping wheels 22 and second clamping wheels 23.

[0044] The auxiliary positioning mechanism 30 comprises a double-station clamping assembly 31 assembled at the position of the welding scar ring of the metal ring, and a pull rod 32 connected to the lower side of the double-station clamping assembly 31. A servo cylinder 34 for pulling the pull rod 32 is arranged at the lower side of the pull rod 32 and fixedly assembled inside the workbench.

[0045] In the operation process, first, the double-station clamping assembly 31 is assembled at the position of the welding scar ring of the metal ring, and then the metal ring is placed on the clamping wheel one 22. Then, the pull rod 32 is connected to the output end of the servo cylinder 34, and the locking structure on the side of the movable plate 21 is loosened, so that the movable plate 21 is in a movable state at the side of the rotating frame 11. Then, the servo cylinder 34 is controlled to pull the metal ring supported by the clamping wheel one 22 downward through the pull rod 32 and the double-station clamping assembly 31, so that the axis of the welding scar ring is lowered to a position at the same height as the rotating shaft of the rotating seat 12. At this time, the welding scar ring is coaxial with the rotating seat 12. During the downward movement of the metal ring, the outer surface of the metal ring pushes the clamping wheel one 22, so that the movable plate 21 automatically and adaptively moves at the corresponding side of the rotating frame 11. The final stop position of the clamping wheel one 22 is the point position that satisfies the fixing of the welding scar ring at the preset position. Finally, the clamping wheel one 22 is locked at the side of the rotating frame 11 through the locking structure, and the position of the movable plate 21 is adjusted. The movable plate 21 at this position can ensure that the welding scar ring of the same type of metal ring is accurately positioned at the preset position.

[0046] After the position adjustment of the clamping wheel one 22 is completed, the double-station clamping assembly 31 can be disassembled from the metal ring and properly stored. When subsequent grinding of other types of metal rings is needed, the above adjustment process is repeated.

[0047] It should be noted that when the metal ring is placed on the clamping wheel one 22, the welding scar ring of the metal ring is directly adjusted to the area of the grinding station on the side of the grinding mechanism 40. Although there may be a slight positional deviation of the welding scar ring in the grinding station area, resulting in a slight deviation between the central axis of the welding scar ring and the rotating shaft of the rotating seat 12, such deviation has little effect on the rotational grinding of the welding scar ring and can be ignored.

[0048] In combination with Figures 2 to 6 , the surface of the rotating frame 11 is provided with a movable groove 111 along the direction of the axis of the rotating seat 12, and a sliding column 211 is fixedly connected to the side of the movable plate 21 and movably arranged inside the movable groove 111.

[0049] The locking structure comprises a push plate 25 arranged on the rotary frame 11 away from the movable plate 21, and the push plate 25 is provided with a circular hole on the surface and is sleeved on the outer surface of the sliding column 211 through the circular hole. The outer end surface of the sliding column 211 is provided with a thread, and the thread surface is connected with a nut. When the nut is tightened, the push plate 25 is clamped with the surface of the rotary frame 11 and the movable plate 21, so as to fix the position of the movable plate 21; when the nut is loosened, the movable plate 21 can be moved horizontally on one side of the rotary frame 11 through the guiding effect of the movable groove 111 on the sliding column 211.

[0050] In addition, the push plate 25 is provided with a push spring 251 close to the rotary seat 12. In the case of loosening the above-mentioned nut, the push spring 251 directly pushes the movable plate 21 to the outer end of the rotary frame 11. This design facilitates the metal ring pulled downward by the double-station clamping assembly 31 to smoothly push the clamping wheel one 22 during the process of adjusting the position of the clamping wheel one 22. Further, it ensures that the movable plate 21 moves to the corresponding position under the condition that the metal ring pushes the clamping wheel one 22, thereby improving the position accuracy of the movable plate 21 self-adapting to the above-mentioned condition.

[0051] In combination Figures 4 to 6 , the upper side of the movable plate 21 is rotatably connected with one end of the rotary plate 24, and a torsion spring 213 is arranged at the rotatable connection position, which can push the outer end of the rotary plate 24 to rotate towards the metal ring.

[0052] The lower side of the rotary plate 24 is provided with an extension block 212, and the side surface of the movable plate 21 is provided with a cylinder 26, which is rotatably assembled on one side of the movable plate 21, and the output end of the cylinder 26 is rotatably connected with one end of the extension block 212. By pushing the extension block 212 through the cylinder 26, one end of the rotary plate 24 with the clamping wheel two 23 can be rotated towards the inner surface of the metal ring, so that the clamping wheel one 22 and the clamping wheel two 23 cooperate to clamp the metal ring. On the contrary, by pulling the extension block 212 through the cylinder 26, the clamping wheel two 23 can be separated from the inner surface of the metal ring, so as to loosen the clamping of the metal ring.

[0053] During the process of adjusting the position of the movable plate 21, only the elastic force of the torsion spring 213 is used to push the rotary plate 24, so that the clamping wheel two 23 is attached to the inner surface of the metal ring, thereby realizing self-adaptive support of the metal ring. When the metal ring pulled downward by the double-station clamping assembly 31 pushes the clamping wheel one 22 to move, the clamping wheel two 23 can maintain the clamping force of the metal ring through the elastic force of the torsion spring 213, so as to ensure that the metal ring remains stable during the movement.

[0054] In combination Figures 2 to 3 and Figures 7 to 9The double-station clamping assembly 31 comprises an electric control base 311 and four clamping jaws 312 arranged on one side of the electric control base 311. The lower side of the electric control base 311 is fixedly connected with the pull rod 32 through a connecting frame 313, and the clamping centers of the four clamping jaws 312 are located directly above the pull rod 32.

[0055] The clamping jaws 312 are designed in an arc shape, and the upper and lower clamping jaws 312 correspond to each other among the four clamping jaws 312. Through the control of the electric control base 311, the two corresponding clamping jaws 312 can move towards each other or away from each other synchronously. The four clamping jaws 312 clamp the position of the metal ring welding scar ring, and can clamp the welding scar ring in the center on one side of the electric control base 311. This design facilitates the handling of metal rings with different cross-sectional diameters, accurately positions the center of the welding scar ring, and further facilitates the adjustment of the center of the welding scar ring to the same height as the rotating shaft of the rotating seat 12.

[0056] The lower end of the pull rod 32 is fixedly connected with a buckle rod 321, and one end of the buckle rod 321 exceeds the space corresponding to the side of the polishing belt of the polishing belt assembly. The output end of the servo cylinder 34 is fixedly connected with a buckle cap 33, and the buckle rod 321 and the buckle cap 33 are movably connected. Through the arrangement of the buckle rod 321, the installation displacement of the servo cylinder 34 and the installation position of the polishing belt assembly are avoided.

[0057] Before adjusting the position of the movable plate 21, the buckle cap 33 needs to be raised to a certain position to ensure that after the double-station clamping assembly 31 is clamped to the surface of the metal ring and the metal ring is placed on the clamping wheel 22, the buckle rod 321 can be located below the buckle cap 33. Then, the servo cylinder 34 is controlled to pull down the buckle cap 33, and the buckle cap 33 can be automatically connected with the buckle rod 321, and further pull down the metal ring.

[0058] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
