DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0027] like Figure 1 As shown, the anti-deviation forging head for bearing ring processing described in this embodiment includes a limit tube 10, a follower limit mechanism 20, a support fixture 30, a rolling guide mechanism 40 and a forging head 50. The limit tube 10 has a rolling guide mechanism 40 fixed inside it for limiting the forging head 50 to be in the center position. The limit tube 10 has a follower limit mechanism 20 located above the rolling guide mechanism 40. The follower limit mechanism 20 is fixedly connected to the forging head 50. A plurality of support fixtures 30 are evenly fixed on the outer wall of the limit tube 10.

[0028] A follow-up limiting mechanism 20 is provided inside the limiting tube 10 and moves with the forging head 50. The follow-up limiting mechanism 20 is rollingly connected to the limiting tube 10 to assist in limiting the forging head 50 to move only in the vertical direction without causing any positional deviation. A rolling guide mechanism 40 is fixed inside the limiting tube 10 and is rollingly connected to the forging head 50 to further limit the movement of the forging head 50 in the vertical direction without causing any shaking in other directions. In addition, the follow-up limiting mechanism 20 is combined with the setting of the rolling guide mechanism 40, which can, on the one hand, achieve a better limiting effect on the forging head 50, and on the other hand, when one is damaged, the other can also be used normally, thereby not affecting the use of the forging head 50 and achieving a better use effect.

[0029] like Figure 2 As shown, the follow-up limiting mechanism 20 includes a fixed ring 21, a fixed bearing 22, a fixed frame 23, a rotating shaft 24 and a moving wheel 25. The inner wall of the fixed bearing 22 is welded to the forging head 50. The outer wall of the fixed bearing 22 is provided with a fixed ring 21. The fixed frames 23 are fixed on the outer wall of the fixed ring 21 in a normal triangle distribution. A rotating shaft 24 is provided between the fixed frames 23. The moving wheel 25 is rotatably connected to the rotating shaft 24.

[0030] A fixed bearing 22 is welded on the inner wall of the fixed bearing 22, and a fixed ring 21 is provided on the outer wall of the fixed bearing 22. Fixed frames 23 are fixed on the outer wall of the fixed ring 21 in a regular triangle distribution. A rotating shaft 24 is provided between the fixed frames 23, and a moving wheel 25 is rotatably connected to the rotating shaft 24. This structural setting can make the moving wheel 25 contact the inner wall of the limiting tube 10, thereby limiting the position of the fixed bearing 22. The forging head 50 will only move in the vertical direction and will not shake in other directions, resulting in a better use effect. The fixed frames 23 are fixed on the outer wall of the fixed ring 21 in a regular triangle distribution, so that the moving wheel 25 has a better limiting effect on the fixed ring 21.

[0031] like Figure 3-4 As shown, the rolling guide mechanism 40 includes a first fixed plate 41, a second fixed plate 42, a rolling limiter 43 and a through hole 44. The first fixed plate 41 and the second fixed plate 42 are both disc-shaped structures. A plurality of rolling limiters 43 are evenly arranged between the first fixed plate 41 and the second fixed plate 42. A through hole 44 is opened at the center of the first fixed plate 41 and the second fixed plate 42.

[0032] The first fixing plate 41 and the second fixing plate 42 can limit the rolling limiter 43. The rolling limiter 43 can limit the position of the forging head 50 so that the forging head 50 can only move in the vertical direction, which has a better use effect.

[0033] like Figure 5 As shown, the rolling limiter 43 includes a rotating wheel 431, a fixing rod 432, a triangular fixing rod 433 and a support column 434. The support column 434 is arranged between the first fixing plate 41 and the second fixing plate 42. The triangular fixing rod 433 is symmetrically fixed on the support column 434. The fixing rod 432 is vertically arranged at the corner of the triangular fixing rod 433, and the rotating wheel 431 is rotatably connected to the fixing rod 432.

[0034] The support column 434 is symmetrically fixed with a triangular fixing rod 433, and a fixing rod 432 is vertically arranged at the corner of the triangular fixing rod 433. The fixing rod 432 is rotatably connected to the rotating wheel 431. This structural arrangement can make the position of the rotating wheel 431 more stable and will not cause positional deviation, thereby having a better limiting effect on the forging head 50; the support column 434 is arranged between the first fixing plate 41 and the second fixing plate 42, which can make the position between the first fixing plate 41 and the second fixing plate 42 more stable, less prone to deformation, and better in use.

[0035] like Figure 3As shown, an elastic protective member 60 is provided at the position of the rolling limit member 43 on the top of the first fixed plate 41, and the elastic protective member 60 includes a fixed spring 61 and a baffle 62. The fixed spring 61 is fixed on the top of the first fixed plate 41, and a baffle 62 is provided on the top of the fixed spring 61. This structural arrangement can buffer the follow-up limit mechanism 20 when the follow-up limit mechanism 20 as a whole accidentally falls off, thereby preventing the falling of the follow-up limit mechanism 20 from causing damage to the rolling guide mechanism 40, thereby extending its service life.

[0036] like Figure 3 As shown, a limiting ring 72 is fixed on the inner wall of the limiting tube 10 at the bottom of the second fixing plate 42, and a positioning bolt 71 connected to the second fixing plate 42 is provided in the limiting ring 72. Through this structural setting, the overall position of the rolling guide mechanism 40 can be further limited, making the position of the rolling guide mechanism 40 more stable.

[0037] like Figure 6 As shown, the supporting fixing member 30 includes a fixing bolt 31, a fixing folding plate 32 and a connecting rod 33. Two fixing folding plates 32 are provided, and the two fixing folding plates 32 are symmetrically fixed on the outer wall of the limiting tube 10. A connecting rod 33 is fixed between the fixing folding plates 32, and a fixing bolt 31 is provided on the fixing folding plate 32. In this structure, the position of the limiting tube 10 can be made more stable without offset, thereby ensuring that the follow-up limiting mechanism 20 and the rolling guide mechanism 40 support the forging head 50 to move in the vertical direction, and the use effect is better.

[0038] The anti-deviation method of the anti-deviation forging head for processing a bearing ring comprises the following steps:

[0039] S1. Limitation of the position limiting tube 10: The position limiting tube 10 is fixed on the forging machine through the supporting fixture 30 to fix the position of the position limiting tube 10;

[0040] S2, the rolling guide mechanism 40 is defined as follows: the first fixing plate 41 and the second fixing plate 42 are fixed in the limiting tube 10, and the rolling guide mechanism 40 in the first fixing plate 41 and the second fixing plate 42 performs rolling support on the forging head 50 to assist in limiting the position of the forging head 50;

[0041] S3. Definition of the follower limiting mechanism 20: The follower limiting mechanism 20 is fixed on the forging head 50 as a whole, and the moving wheel 25 connected to the fixed ring 21 contacts the inner wall of the limiting tube 10. The forging head 50 drives the follower limiting mechanism 20 to move in the limiting tube 10, further limiting the position of the forging head 50.

[0042] The support fixing members 30 are provided in multiple groups, three support fixing members 30 form a group, and the support fixing members 30 in one group are distributed in a regular triangle and fixed on the outer wall of the limiting tube 10, so that the support fixing members 30 can limit the limiting tube 10 more stably and have a better use effect.
