DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 A bearing outer ring blank forging in this embodiment includes a blank casting as a whole 1, and the blank casting as a whole 1 includes an outer ring casting 101. The upper and lower sides of the outer ring casting 101 are provided with connecting grooves 102. The connecting grooves 102 can effectively reduce the overall material consumption, thereby effectively improving the utilization rate of resources. An oil inlet groove 103 connected to the top connecting groove 102 is opened inside the outer ring casting 101. Through the oil inlet groove 103, it is convenient to add lubricating oil to the inside of the ball groove 105, so that the whole is more practical. A stamping hole 104 is opened on the top of the outer ring casting 101, and a ball groove 105 connected to the stamping hole 104 is opened inside the outer ring casting 101.

[0023] In addition, the bottom of the blank casting as a whole 1 is movably connected to a support platform 2, the bottom of the support platform 2 is fixed with a support plate 3, the top of the support plate 3 is fixed with a drive motor 4, and the output shaft of the drive motor 4 is fixed with a fixing component 5 rotatably connected to the support platform 2, and the fixing component 5 is used to fix the blank casting as a whole 1.

[0024] In general, the oil inlet groove 103 makes it easy to add lubricating oil to the inside of the ball groove 105, while the oil inlet groove 103 on the outer ring casting 101 is not connected to the ball groove 105. During subsequent fine processing, the size of the connection between the ball groove 105 and the oil inlet groove 103 will be controlled, making the whole more practical.

[0025] See also Figure 3 In order to facilitate fixation, the fixing component 5 in this embodiment includes a rotating rod 501 and four pushing blocks 502, a squeezing plate 503 and a limit block 504. The rotating rod 501 is fixed to the output shaft of the driving motor 4, and the rotating rod 501 is rotatably connected to the support platform 2. A fixing hole is opened inside the support platform 2, and a fixed bearing is fixed inside the fixing hole. The inside of the fixed bearing is fixed to the rotating rod 501. By setting the fixed bearing, the rotation stability of the rotating rod 501 can be effectively improved.

[0026] The outer surface of the rotating rod 501 is threadedly connected to the pushing block 502. The rotating rod 501 is a positive and negative threaded screw. The interiors of the two pushing blocks 502 on the left are provided with positive threaded holes that are compatible with the positive threaded screw. The interiors of the two pushing blocks 502 on the right are provided with negative threaded holes that are compatible with the negative threaded screw. Through the provision of positive and negative threaded screws, when the rotating rod 501 rotates, the pushing block 502 that cannot rotate will move due to the extrusion of the threads. The outer surface of the pushing block 502 is fixed to the extrusion plate 503. Sponge pads are fixed on the opposite side of the two extrusion plates 503 on the left and the opposite side of the two extrusion plates 503 on the right. The provision of sponge pads can effectively improve the stability of the fixation.

[0027] In addition, the extrusion plate 503 is slidably connected to the limit block 504, and a stabilizing block is fixed on the outer surface of the extrusion plate 503, and the stabilizing block is slidably connected to the limit groove 505. A limit groove 505 slidably connected to the extrusion plate 503 is provided on the top of the limit block 504, and a through hole 506 connected to the limit groove 505 is provided inside the limit block 504. The setting of the limit groove 505 allows the limit block 504 to effectively limit the rotation of the extrusion plate 503, thereby preventing the push block 502 from rotating. The left through hole 506 and the right through hole 506 are both located on the front side of the limit block 504, and the two middle through holes 506 are located on the back side of the limit block 504. The setting of the through hole 506 makes it impossible for the limit block 504 to continue to limit the rotation of the extrusion plate 503 when the extrusion plate 503 moves to the through hole 506, and the limit block 504 is fixed to the support plate 3.

[0028] In general, the limit block 504 can effectively limit the rotation of the extrusion plate 503, and the through hole 506 can remove the limit on the extrusion plate 503 by the limit block 504, so that the extrusion plate 503 can rotate with the rotating rod 501, thereby effectively avoiding the extrusion plate 503 from affecting the subsequent processing.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] When the outer surface of the blank casting 1 needs to be processed, the driving motor 4 is started to rotate the rotating rod 501, so that the pushing block 502 that cannot rotate is moved due to the extrusion of the thread, so that the two extrusion plates 503 located inside the blank casting 1 are moved toward the blank casting 1, and then the blank casting 1 is supported internally. When the rotating rod 501 rotates, when the two extrusion plates 503 located outside the blank casting 1 move to the through hole 506 connected to the limiting groove 505, the limiting block 504 at this time cannot limit the rotation of the extrusion plate 503, so that the extrusion plate 503 and the pushing block 50 2 rotates together with the rotating rod 501, so that the extrusion plate 503 rotates to be parallel to the support plate 3, so that the extrusion plate 503 does not affect the subsequent processing. When the internal part needs to be processed, the driving motor 4 is started to rotate in the opposite direction, so that the two extrusion plates 503 on the outer side of the blank casting as a whole 1 are rotated to the inside of the through hole 506 again, and then the extrusion plates 503 are restricted from rotating by the limit block 504 again, so that the extrusion plates 503 are moved toward the blank casting as a whole 1 again due to the extrusion of the thread, and the blank casting as a whole 1 is clamped and fixed. The overall structure is simple, and the fixing efficiency is effectively improved, so that the overall structure is more practical.
