[0002] In the field of mechanical manufacturing, the end face quality of metal rings (such as metal rings and metal tubes), especially bearing rings, has a significant impact on subsequent assembly accuracy and product performance. Controlling the flatness and roughness of the end face not only affects the bearing's rotational accuracy but also its load distribution and lifespan. Therefore, how to efficiently, stably, and precisely grind the end faces of bearing rings has become one of the key issues of concern in this field.

[0003] Currently, in most small and medium-sized enterprises or workshops, the grinding of bearing ring end faces is still done manually using traditional hand tools. Operators must manually grind the workpiece on a rotating grinding disc, which is labor-intensive, inefficient, and the grinding quality is significantly affected by human factors. Especially when dealing with a large number of bearing ring machining tasks, it is difficult to achieve consistency and precision control of the end face machining, which can easily lead to quality defects such as runout and excessive deviation of the bearing ring end face. Utility Model Content

[0025] 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.

[0026] As shown in the figure, a grinding device for precision grinding the end face of a metal ring includes:

[0027] The rotatable grinding disc 2 has its rotation center perpendicular to the horizontal plane. The upper surface of the grinding disc 2 is the grinding surface, which is set to support the metal ring workpiece 11 to be ground, so that the end face of the workpiece 11 is in close contact with the grinding surface. In this example, the grinding disc 2 is mounted on a grinding machine 1. The grinding machine 1 is a commonly used device for grinding workpiece 11 in the prior art. Its internal structure and principle will not be described in detail here. The grinding disc 2 is rotated by a motor inside the grinding machine 1.

[0028] A rotatable drive wheel 10 is located on one side of the grinding disc 2 and contacts the outer wall of the workpiece 11. It is configured to drive the workpiece 11 to rotate around its own axis. Specifically, a motor bracket 5 is fixed on one side of the grinding machine 1. A reducer 6 and a drive motor 7 are mounted on the motor bracket 5. The output shaft of the drive motor 7 is connected to the reducer 6, and the output shaft of the reducer 6 is connected to the drive wheel 10. It is mainly used to make the drive wheel 10 rotate, so that the workpiece 11 can be driven to rotate after the drive wheel 10 contacts the workpiece 11. In addition, in order to avoid the problem of relative slippage between the drive wheel 10 and the workpiece 11, a rubber sleeve can be fitted in the circumferential direction of the workpiece 11 to increase the friction between the drive wheel 10 and the workpiece 11, so that the workpiece 11 can achieve stable rotation.

[0029] A rotatable auxiliary support wheel 9 is located on the other side of the workpiece 11 and contacts the outer wall of the workpiece 11. It is used to cooperate with the drive wheel 10 to limit the position of the workpiece 11. The motor bracket 5 is equipped with an angle-adjustable linkage mechanism 3. The auxiliary support wheel 9 is installed at the end of the linkage mechanism 3 through a bearing. The auxiliary support wheel 9 is installed at the end of the linkage mechanism 3, so that its position can be flexibly adjusted according to the outer diameter of the workpiece 11, which expands the adaptability range of the grinding device. At the same time, the support wheel is connected by a bearing, which reduces the motion resistance and makes the rotation of the workpiece 11 smoother, which helps to improve the uniformity of grinding.

[0030] The minimum distance between the auxiliary support wheel 9 and the drive wheel 10 is less than the outer diameter of the workpiece 11. The workpiece 11 is pressed against the grinding surface under its own gravity. Driven by the drive wheel 10, it rotates and completes the grinding of its end face. By utilizing the cooperation between the drive wheel 10 and the auxiliary support wheel 9, the workpiece 11 is driven to rotate to facilitate uniform grinding of the end face. On the other hand, it ensures that the workpiece 11 is always stably kept in the set grinding position, which solves the problems of low accuracy and poor repeatability of traditional handheld or non-positioning grinding methods.

[0031] Specifically, a pressure block fixture 4 is provided above the workpiece 11. The pressure block fixture 4 is detachably mounted on the surface of the workpiece 11. The pressure block fixture 4 is a sleeve structure or a shaft structure, designed to enhance the contact force between the workpiece 11 and the grinding disc 2. Specifically, the number of pressure block fixtures 4 can be designed according to the grinding requirements, and the contact force between the workpiece 11 and the grinding disc 2 can be changed by changing the number of them. By adding the pressure block fixture 4 above the workpiece 11, a further clamping force is applied on top of the workpiece 11's own weight, which can enhance the contact pressure between the workpiece 11 and the grinding disc 2, improve grinding efficiency and flatness control, and is especially suitable for application scenarios that require greater grinding force or where the workpiece 11 is relatively lightweight.

[0032] Specifically, the linkage mechanism 3 includes a first link 301, a second link 302, and a third link 303. The first link 301 is bolted to the motor bracket 5. The second link 302 is bolted to the first link 301. The third link 303 is bolted to the end of the second link 302, and the angle of the third link 303 relative to the second link 302 can be adjusted. After adjusting the angle between the third link 303 and the second link 302, the third link 303 is fastened to the second link 302 with bolts to adjust the position of the auxiliary support wheel 9. This configuration allows for flexible adjustment of the position of the auxiliary support wheel 9 according to the size of the metal ring, offering advantages such as structural flexibility and strong adaptability.

[0033] The system also includes a protective cover 8, in which the drive motor 7, reducer 6, and motor bracket 5 are all housed. A suction pipe is connected to the side wall of the protective cover 8, with the end of the suction pipe connected to a vacuum cleaner. The protective cover 8 can effectively enclose key moving parts such as the drive motor 7 and reducer 6, improving operational safety and equipment protection performance. Connecting the suction pipe can promptly remove dust generated during the grinding process, optimizing the working environment and extending the service life of the equipment.

[0034] When using this precision grinding device for the end face of a metal ring, the workpiece 11 is placed on the grinding surface of the grinding disc 2. Since the drive wheel 10 and the auxiliary support wheel 9 always limit the workpiece 11 to a designated position, the end face of the workpiece 11 can form a relative frictional contact with the grinding disc 2, achieving continuous and uniform grinding of the end face. At the same time, the rotation of the drive wheel 10 can drive the workpiece 11 to rotate around its own axis, further improving the uniformity of end face grinding. The contact force between the workpiece 11 and the surface of the grinding disc 2 can be changed by setting the pressure block fixture 4. The number of pressure block fixtures 4 can be flexibly changed according to actual working needs to improve grinding efficiency and flatness control.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
