Bearing stripping principle: when the needle roller is installed, the inner ring shaft 404 of the bearing stripping mechanism 4 moves to the installation position of the bearing needle roller through the third transfer module 401 and props against the bearing needle roller, after the needle roller is installed, the material taking part (the inner ring shaft 404 part) of the bearing stripping mechanism 4 continues to move forward until the inner ring shaft 404 is inserted into the inner ring of the bearing, at the moment, the outer ring section of the bearing and the needle roller prop against the outer section of the outer ring sleeve 405, so that the structure is stable, then the third transfer module 401 returns to the position of the blanking hole 406 with the material taking part, then the jacking cylinder 4011 acts, so that the push plate 4015 pushes the outer ring sleeve 405 outwards, and the bearing is separated from the inner ring shaft 404 and falls into the blanking hole 406; before stripping, the number of the rolling pins is detected by detecting the negative pressure in the mandrel 302, and the action of the distributor is controlled by the control system, so that the finished product enters the finished product box 409 along the first material distributing slide 407, and the defective product enters the defective product box 4010 along the second material distributing slide 408.
The bearing assembly machine designed by the invention can realize full-automatic taking and feeding of the inner ring and the outer ring of the bearing, full-automatic feeding and assembly of the needle bearing, full-automatic taking and stripping of the assembled bearing and strict monitoring of the quality of the bearing; each part conveying efficiency is high, and the installation accuracy is good, has improved the yields, has reduced the cost of labor, and is safe high-efficient, is fit for promoting.
