The assembly principle of the rolling needles is as follows: the material taking module 203 of the inner and outer ring conveying mechanism 2 sends the inner ring and the outer ring of the bearing into the positioning hole 309 on the positioning plate 308, and then the inner ring shaft 404 of the bearing stripping mechanism 4 moves to the mounting position of the bearing roller needle through the third transfer module 401 and is abutted against the mounting position; then, the needles are conveyed to the positions of the needle mounting holes 306 in the second mounting plate 305 through the needle conveying member 307 (the needles in the needle conveying member 307 are horizontally placed and fall in sequence), at this time, the mounting end of the spindle 302 enters the needle mounting holes 306, the first needle falls to the needle storage groove 303 of the spindle 302, then the spindle 302 rotates one needle storage groove 303 through the stepping motor 3018, the second needle falls to the needle storage groove 303 until the needle is full (the vacuum generator vacuumizes the cavity in the spindle 302 through the connecting hole 5012 and the butt joint hole 5010, the needle is full when the set pressure is detected by the negative pressure sensor, the needle pushing action can be executed through the control system, if the set pressure is not detected by the negative pressure sensor, which indicates that the needle storage groove 303 is not full, the control system controls the bearing stripping mechanism 4 to feed the currently mounted bearing into the defective magazine 4010), after the groove is filled for one circle, the servo electric cylinder 3016 controls the needle roller push ring 304 to enter the needle roller installation groove, the needle rollers in the needle roller storage groove 303 are all pushed between the inner ring and the outer ring of the bearing, then the mandrel 302 is controlled by a push shaft cylinder 3014 to exit from the needle roller mounting hole 306, the spacer feed plate 3012 is controlled by a spacer feed cylinder to feed the spacer to one axial side of the needle roller mounting hole 306 (the spacer enters the spacer feed hole 3013 through the spacer feed hole 3010 and is then conveyed to a position outside the needle roller mounting hole 306), then the needle roller push ring 304 is controlled by the servo electric cylinder 3016 to push the spacer into the space between the inner ring and the outer ring of the bearing (the spacer is behind the needle roller), then the push rod cylinder control mandrel 302 enters the needle roller mounting hole 306 again to mount the needle rollers, the needle rollers are pushed into the bearing again after the groove is filled, needle roller assembly of the double-circle needle roller bearing is completed, and then the bearing is taken off from the outside by the bearing material taking-off mechanism 4.

The bearing stripping principle is as follows: 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 abuts against the installation position, 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 forwards 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 abut against the outer section of the outer ring sleeve 405 to ensure the structure to be stable, then the third transfer module 401 drives the material taking part to return to the position of the blanking hole 406, then the sleeve jacking cylinder 4011 acts to enable the push plate 4015 to push the outer ring sleeve 405 outwards, so that the bearing is separated from the inner ring shaft 404 and falls to the blanking hole; before stripping, the quantity of the needle rollers is detected in a negative pressure detection mode in the mandrel 302, the distributor is controlled by the control system to move, finished products enter the finished product material box 409 along the first distributing slide 407, and defective products enter the defective product material box 4010 along the second distributing slide 408.
