Description

Technical Field

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

[0002] Needle roller bearing processing is a complex and delicate process. Material preparation: The main material of needle roller bearings is high carbon chromium steel. Before processing, it is necessary to select high-quality high carbon chromium steel, which is the basis for ensuring the quality and performance of subsequent processing. Forging and turning: After forging, the raw materials are formed into bearing ring blanks. Forging can make the organizational structure of the raw materials denser and streamlined, thereby improving the reliability and service life of the bearings. After that, turning is carried out to perform preliminary shape processing on the bearing rings. Heat treatment: Heat treatment is to treat the bearing rings after forging and turning at high temperature. It can improve the wear resistance and hardness of the bearings, which is an important factor affecting the reliability and service life of the bearings. Grinding and super finishing: This step is to further improve the accuracy and surface quality of the bearings. Grinding is mainly to grind the inner and outer rings and needle rollers accurately to achieve the designed dimensional accuracy and shape accuracy. Super finishing is to further fine-tune the bearing surface through special abrasives and processes to improve its surface roughness and accuracy.

[0003] Needle roller bearing processing includes grinding the needle roller bearings. However, considering the different specifications of needle roller bearings, the traditional grinding mechanism is not convenient for grinding needle roller bearings of different sizes, which greatly reduces the efficiency of needle roller bearing processing and is extremely inconvenient. Therefore, a grinding device for needle roller bearing processing is urgently needed to solve the above problems. Utility Model Content
