A precision bearing width grinding device and grinding method thereof

Abstract

The invention relates to the technical field of mechanical processing equipment, and discloses a precision bearing width grinding device, which includes a machine base, a support frame is fixedly installed at a diagonal position on the top surface of the machine base, and an upper grinding disc is movably installed at the bottom of the support frame. The bottom of the upper grinding disc is uniformly provided with a liquid outlet groove, and the middle part of the top surface of the machine base is fixedly installed with a lower grinding cylinder. A planetary wheel that meshes externally with the rotating tooth column gear is installed, and a slag discharge device is fixedly installed inside the lower grinding cylinder between the rotating grinding table and the rotating tooth column, and the lower grinding cylinder is located at the bottom of the center of the rotating grinding table There is a grinding disc installation hole, and a liquid collection chamber is opened inside the bottom of the lower grinding cylinder. By designing a plurality of rotating rotating grinding discs and rotating tooth column meshing rotation and slag discharge devices, the device has high grinding accuracy and long service life. The advantages.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a precision bearing width grinding device and a grinding method thereof. Background technique [0002] Bearing is a kind of part used a lot in the machinery industry, because it is easy to use and simple in structure, it is very popular, so now there are basically bearings in mechanical equipment, but the requirements for bearings in high-precision industry equipment are high and must be precision Therefore, the grinding of bearings becomes particularly important. The existing grinders use end grinders to grind the width of bearings. The grinding is convenient and has a large range, but there are still some problems: [0003] 1. When grinding, because there is a star wheel structure on the lower grinding disc, the bearing is installed in the hole inside it for grinding, but the friction of the grinding disc at the bottom is different in the axial direction...

AI Technical Summary

Problems solved by technology

[0003] 1. When grinding, because there is a star wheel structure on the lower grinding disc, the bearing is installed in the hole inside it for grinding, but the friction of the grinding disc at the bottom is different in the axial direction. The ring and the outer ring are less ground, which will lead to different friction losses in different parts of the grinding disc, which will result in a short service life of the grinding disc, and it is not conducive to grinding, and it is easy to cause grinding errors, which is not good for precision bearings. Allowed;

[0004] 2. Heat will be generated during the grinding process, so the cooling liquid is very important, but in practice, the grinding will produce small powdery abrasive grains, which will cause Grinding small particles while grinding the bearing will not only damage the bearing but also reduce the service life of the grinding disc
