Description

Technical Field

[0001] The utility model relates to the technical field of grinding component equipment, in particular to a grinding component for needle roller bearing production. Background Art

[0002] Bearings are one of the important connecting components in various mechanical equipment. They can realize the function of rotating connecting components and effectively reduce wear while ensuring the rotation accuracy. The processing accuracy of bearings will affect the running stability of various mechanical devices. Therefore, the bearing rings of bearings need to be deburred by grinding and polishing during the processing. In order to adapt to components with different functions and sizes, the sizes of bearings are also diverse. Therefore, the grinding mechanism used to grind the inner wall of the bearing ring needs to have a certain degree of adjustability to adapt to bearing rings of different sizes in the actual processing process. To meet this demand, a new grinding mechanism for needle roller bearing processing can be proposed. By designing an adjustable grinding head mounting mechanism, the application scope of the grinding device can be expanded, thereby improving the practicality of the grinding mechanism.

[0003] The Chinese patent application number is CN202121443011.9, which discloses a grinding mechanism for needle roller bearing processing, which solves the problem in the prior art that the grinding device for bearing processing is inconvenient to adjust according to the size of the bearing. A grinding mechanism for needle roller bearing processing includes a base, the top of the base is fixedly connected to a support frame, the support frame is a U-shaped structure, a support plate is provided on the inner side of the support frame, the top of the support frame is fixedly connected to a cylinder, the piston rod of the cylinder passes through the support frame and is fixedly connected to the support plate and is slidably connected to the support frame at the penetration point, the bottom of the support plate is bolted and fixedly connected to a servo motor, and a connecting assembly is provided at the bottom of the servo motor. The utility model realizes the adjustability of the position of the grinding head and the bearing fixing seat by designing an adjustable connecting mechanism, broadens the scope of application of the grinding device, and simplifies the adjustment steps of the grinding device.

[0004] The grinding mechanism for needle roller bearing processing disclosed in the above document has the following defects: when the grinding head is grinding the workpiece, the high-speed rotation of the grinding head will generate vibration, and the vibration will cause the bearing to shift, so that the grinding range of the grinding head on the bearing will also shift, so the bearing needs to be fixed, otherwise the processing quality of the grinding mechanism will be greatly reduced.

[0005] It can be seen from this that the existing grinding mechanism does not have the function of enhancing the clamping and fixing of the bearing, and it is necessary to improve the existing deficiencies and provide a function that can clamp and fix the bearing. Utility Model Content
