However, these devices have some shortcomings in practical applications. For example, bearings are prone to positional shifts or unstable rotation during grinding, resulting in uneven grinding effects; the movement and positioning of the grinding device are not flexible enough, affecting grinding efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2This utility model provides a technical solution: This utility model relates to a grinding device for the outer ring surface of bearings. The device mainly consists of a base plate 1, on which a support frame 2 is mounted. The purpose of the support frame 2 is to provide a stable support structure, ensuring the stability of the entire device during operation. A rotating slide 3 capable of 360-degree rotation is installed on top of the support frame 2, allowing for convenient all-around grinding of the bearing outer ring.

[0021] A pneumatic chuck 4 is mounted on the rotary slide 3. Driven by air pressure, the pneumatic chuck 4 clamps the outer ring of the bearing. The chuck's design ensures the outer ring is securely fixed in the clamping position, guaranteeing accuracy and stability during the grinding process. To further improve clamping reliability, a fixed shaft 5 is laterally clamped on the pneumatic chuck 4. The fixed shaft 5 is designed to provide stable axial support, preventing the outer ring of the bearing from shifting during grinding.

[0022] A non-slip sleeve 6 is fitted onto the fixed shaft 5. The function of the non-slip sleeve 6 is to prevent relative sliding between the outer ring of the bearing and the fixed shaft 5 during the grinding process, thereby ensuring the accuracy of grinding. A bearing 7 is fitted onto the non-slip sleeve 6. The bearing 7 is designed to provide smooth rotation during the grinding process and reduce unnecessary friction and wear.

[0023] In addition, a lateral moving device 8 is also provided on the base plate 1. The lateral moving device 8 is designed to realize the lateral movement of the grinding device, so as to facilitate the grinding of different parts of the bearing outer ring. A first rod cylinder 9 is installed on the lateral moving device 8. The drive end of the first rod cylinder 9 is connected to a second rod cylinder 10. The second rod cylinder 10 is designed to provide greater power and more precise control. The bottom end of the second rod cylinder is provided with a support column, and the lower end of the support column is provided with an auxiliary slide rail. The support column slides on the auxiliary slide rail to prevent the second rod cylinder 10 from tilting and keep the second rod cylinder 10 stable.

[0024] The drive end of the second rod cylinder 10 is connected to a fixed base 11. The fixed base 11 is designed to fix the position of the grinding wheel 12 and ensure stability during the grinding process. A grinding wheel 12 is arranged laterally on the fixed base 11. The grinding wheel 12 is designed to grind the outer ring surface of the bearing. The drive end of the grinding wheel 12 is connected to a grinding wheel 13, which abuts against the bearing 7. High-speed rotation of the grinding wheel grinds the outer ring surface of the bearing.

[0025] Specifically, the support frame 2 consists of horizontal and vertical plates, both of which are fixed to the base plate 1. Reinforcing ribs are provided between the horizontal and vertical plates to enhance the stability and strength of the entire support frame. Below the fixed shaft 5, there are two support plates 14, the bottom of which are fixed to the base plate 1. The support plates 14 also have mounting grooves for the fixed shaft 5 to ensure its stability and accuracy.

[0026] Specifically, the lateral movement device 8 is an electric single-axis drive, with its upper moving slide connected to the first rod-driven cylinder 9. Precise lateral movement is achieved through electric drive, ensuring accuracy and efficiency during the grinding process. This design not only improves grinding precision but also increases production efficiency, making the grinding process of the bearing outer ring more stable and reliable.

[0027] Working principle: When this utility model is in operation, the base plate 1 serves as the basic support structure for the entire device; the support frame 2 is installed on the base plate 1 to provide additional stability and support.

[0029] The fixed shaft 5 is laterally clamped in the pneumatic chuck 4 to fix the bearing 7; the anti-slip sleeve 6 is fitted on the fixed shaft 5 to prevent the bearing 7 from sliding during the grinding process.

[0030] Bearing 7 is fitted onto anti-slip sleeve 6, ready for grinding; lateral movement device 8 is installed on base plate 1 to control the lateral movement of the grinding device.

[0031] The first rod cylinder 9 is mounted on the lateral moving device 8 to drive the grinding device to move laterally; the driving end of the second rod cylinder 10 is connected to the first rod cylinder 9 to further control the movement of the grinding device.

[0032] The fixed seat 11 is installed on the drive end of the second rod cylinder 10 and is used to fix the grinding wheel 12; the grinding wheel 12 is installed on the fixed seat 11 and is used to grind the outer ring surface of the bearing 7.

[0033] The grinding wheel 13 is installed on the drive end of the grinding machine 12 and directly contacts the bearing 7 for grinding; the support plate 14 is installed on the base plate 1 to support the bottom of the fixed shaft 5 and ensure its stability; the electric single-axis drive serves as the lateral movement device 8, and its moving slide is connected to the first rod cylinder 9 to achieve precise lateral movement control.

[0034] In actual operation, the pneumatic chuck 4 clamps and rotates the fixed shaft 5, while the lateral movement device 8 controls the movement of the first rod cylinder 9 and the second rod cylinder 10 via an electric single-axis driver, driving the grinding wheel 12 and the grinding wheel 13 to move laterally and grind the outer ring surface of the bearing 7. In this way, precise grinding of the outer ring surface of the bearing can be achieved.
