[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figures 1-5 As shown in the figure, this application discloses a fully automatic cold rolling and reaming device for bearing ring parts, including a base plate 1; a support seat 2 is fixedly installed on one side of the top of the base plate 1, a driven rod 3 is rotatably installed on the support seat 2, a limiting and pushing integrated ring 4 is sleeved on the end of the driven rod 3 near the support seat 2, and a part is sleeved on one side of the limiting and pushing integrated ring 4; a pushing assembly 5 is provided on the outer wall of the support seat 2, the pushing assembly 5 is connected to the limiting and pushing integrated ring 4, and is used to push the limiting and pushing integrated ring 4 to move along the length direction of the driven rod 3; a strip groove is opened on the top of the base plate 1, and several linearly arranged rangefinders 6 are installed in the strip groove, the rangefinders 6 are located directly below the driven rod 3; a protective assembly 7 is provided on the outer wall of the support seat 2, the protective assembly 7 is used to protect the rangefinders 6; a lifting and stabilizing assembly 8 is connected to one side of the top of the base plate 1, the lifting and stabilizing assembly 8 is located at the other end of the driven rod 3; a rolling wheel assembly 9 is installed on the top of the base plate 1.

[0026] The bearing ring part is placed on the driven rod 3 on one side of the limiting and pushing integrated ring 4. Then, the lifting and stabilizing component 8 adjusts the height to fit the end of the driven rod 3 for stable support. The rolling wheel component 9 starts to perform cold rolling and hole enlargement processing on the part. After processing, the pushing component 5 drives the limiting and pushing integrated ring 4 to move along the driven rod 3 and push the part out. In the level detection stage of the driven rod 3, the level status of the driven rod 3 can be accurately judged with the help of the measurement data of multiple rangefinders 6. When the rangefinders 6 are not in use, the protection component 7 always protects the rangefinders 6 from debris.

[0027] The pushing component 5 includes a connecting plate 501, which is fixedly installed on one side of the limiting and pushing integrated ring 4. A circular through hole is opened at the center of the connecting plate 501. The connecting plate 501 is sleeved on the driven rod 3 through the circular through hole. Two limiting posts 502 are symmetrically welded on the outer wall of the connecting plate 501. The support base 2 is provided with corresponding limiting holes that are adapted to the limiting posts 502. The limiting posts 502 pass through the limiting holes. The ends of the two limiting posts 502 away from the connecting plate 501 are jointly installed with a driving base 503. A driving telescopic rod 504 is fixedly installed on the driving base 503. The end of the driving telescopic rod 504 away from the driving base 503 is positioned and connected to the outer wall of the support base 2. An arc-shaped protective cover 505 is fixed on the outer wall of the support base 2.

[0028] When the telescopic rod 504 extends or retracts, it drives the drive seat 503 and the two limiting posts 502 to slide along the limiting holes of the support seat 2. The connecting plate 501 moves synchronously with the limiting posts 502, thereby driving the limiting push integrated ring 4 to slide smoothly along the driven rod 3, realizing the pushing of the parts. The symmetrical limiting posts 502 cooperate with the limiting holes to ensure that the pushing trajectory is stable and does not deviate. The drive telescopic rod 504 provides stable thrust, realizes accurate pushing of parts, improves the efficiency of automated unloading, and ensures smooth connection with subsequent processes.

[0029] The protective assembly 7 includes a protective plate 701 located above the strip groove. One end of the protective plate 701 is fixedly connected to an L-shaped support plate 702. An electric push rod 703 is fixed on the outer wall of the L-shaped support plate 702 away from the protective plate 701. The end of the electric push rod 703 away from the L-shaped support plate 702 is positioned and connected to the outer surface of the support base 2.

[0030] During processing, the electric push rod 703 retracts, causing the L-shaped support plate to move the protective plate 701 above the strip groove, blocking the rangefinder 6. When testing is required, the electric push rod 703 extends, causing the protective plate 701 to move away, exposing the rangefinder 6. During processing, it blocks debris and coolant, protecting the rangefinder 6 from damage. During testing, it quickly moves away without interfering with the measurement, extending the equipment's lifespan and ensuring testing accuracy.

[0031] The lifting and stabilizing assembly 8 includes two lifting push rods 801 that are symmetrically and fixedly connected to the top of the equipment base plate 1. The top ends of the two lifting push rods 801 are fixedly connected to a linkage plate 802. The ends of the two linkage plates 802 away from the lifting push rods 801 are jointly fixed with a U-shaped stabilizing seat 803.

[0032] When the part is placed on the driven rod 3, the two lifting push rods 801 extend and retract synchronously, causing the linkage plate 802 to descend so as not to affect the placement of the part, until the part is placed to one side of the limit push integrated ring 4. Then the two lifting push rods 801 extend and retract synchronously, causing the linkage plate 802 to adjust its height so that the U-shaped stabilizing seat 803 accurately supports the end of the driven rod 3 away from the support seat 2.

[0033] The grinding wheel assembly 9 includes an inverted U-shaped mounting frame fixedly installed on the equipment base plate 1. A telescopic cylinder 902 is fixedly fixed on the top of the mounting frame. An inverted U-shaped positioning frame 903 is fixedly connected to one end of the telescopic cylinder 902. A grinding wheel 904 is rotatably connected inside the positioning frame 903. A drive motor 905 is fixed on the outer wall of the positioning frame 903. The output shaft of the drive motor 905 is connected to the grinding wheel 904.

[0034] Before processing, the telescopic cylinder 902 drives the positioning frame 903 and the rolling wheel 904 to move up and down, adjusting the distance between the rolling wheel 904 and the part on the driven rod 3. During processing, the drive motor 905 drives the rolling wheel 904 to rotate, while the telescopic cylinder 902 applies pressure, causing the rolling wheel 904 to cold roll and enlarge the hole of the part. The telescopic cylinder 902 can flexibly adjust the pressure and distance of the rolling wheel 904 to adapt to the processing of parts of different sizes. The drive motor 905 drives the rolling wheel 904 to rotate stably, ensuring the hole enlargement accuracy. The inverted U-shaped mounting frame and the positioning frame 903 enhance the structural stability and reduce the impact of processing vibration.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
