Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 to 3, the bearing inner ring core positioning device of the present embodiment includes a core positioning main body 1, a head portion of the core positioning main body 1 has a positioning column 2 extending vertically upward, and the positioning column 2 is a cylinder for positioning a bearing inner ring 9 to be processed. Four mounting grooves 7 are distributed on the circumferential outer wall of the positioning column 2 at intervals, the mounting grooves 7 are opened at the top of the positioning column 2, a wear-resistant sheet 3 is embedded in each mounting groove 7, and the peripheral surface of each wear-resistant sheet 3 and the peripheral surface of the positioning column 2 are located on the same peripheral surface. In this embodiment, the wear-resistant sheet 3 is a ceramic wear-resistant sheet to improve the wear-resistant degree of the positioning column 2.
The middle part of the fixed core main body 1 is provided with a transverse mounting hole 4, a fixing shaft 5 is mounted in the transverse rod mounting hole 4, two ends of the fixing shaft 5 extend out of the fixed core main body 1, and two ends of the fixing shaft 5 are respectively provided with a supporting bearing 6. After the bearing inner ring 9 to be processed is arranged in the positioning column 2, the top of the outer ring of the supporting bearing 6 is just supported at the bottom of the bearing inner ring 9, so that the bearing inner ring 9 is better supported and positioned.
In addition, the lower part of the centering body 1 is a mounting part 8, and the centering device is mounted on a supporting device (not shown in the figure) through the mounting part 8.
When the bearing inner ring 9 is processed, the fixed core main body 1 is fixed, and the bearing inner ring 9 to be processed is arranged on the positioning column 2 of the fixed core main body 1 and rotates relative to the positioning column 2. After the wear-resisting piece 3 of ceramic material was installed on reference column 2 to this embodiment, can improve reference column 2's abrasion resistance greatly to avoid reference column 2 to produce wearing and tearing in the course of working, and, carry out the bottom sprag through support bearing 6 to bearing inner race 9, make bearing inner race 9 can obtain more reliable location in the course of working, and then ensure the machining precision.
