The following is a specific description of the solution through specific embodiments.
[0027] Refer to Figures 1-8 shown, a bearing automatic assembly machine includes:
[0028] A frame 1, a bracket 2 provided on the frame 1, and a pressing assembly provided on the bracket 2; the bracket 2 is slidably engaged with the first guide rail 11 and a locking nut is provided at the engagement position to lock the position of the bracket 2.
[0029] On the frame 1, there are a first guide rail 11 and a second guide rail 12 that are parallel to each other. A lifting cylinder 14 installed on the frame 1 is provided in the middle section of the second guide rail 12; two parallel transmission belts are provided in both the first guide rail 11 and the second guide rail 12, and the two transmission belts are connected to a drive motor 13 installed on the frame 1; a tray 141 is provided at the output end of the lifting cylinder 14, a positioning block 142 is provided on the tray 141, and a groove for cooperating with the positioning rod 226 is opened in the positioning block 142; through holes are opened at the relative positions of the first guide rail 11 and the second guide rail 12 and the tray 141, and the through holes are in clearance fit with the tray 141.
[0030] The pressing assembly includes a pressing cylinder 21 mounted on the bracket 2, a frame 22 provided at the output end of the pressing cylinder 21, a lead screw 221 provided inside the frame 22, clamping jaws 223 symmetrically sleeved on the lead screw 221, a fixing plate 222 provided between the clamping jaws 223 and mounted on the frame 22, a positioning rod 226 inserted into the fixing plate 222, and a spring 224 provided between the positioning rod 226 and the fixing plate 222; the lead screw 221 is movably connected to the frame 22, and one end of the lead screw 221 is provided with a servo motor mounted on the frame 22; the clamping jaws 223 are arc-shaped, the clamping jaws 223 are slidably matched with the lead screw 221, and the fixing plate 222 is in clearance fit with the lead screw 221; the positioning rod 226 is slidably matched with the fixing plate 222, and both ends of the spring 224 are respectively connected to the positioning rod 226 and the fixing plate 222.

[0032] Principle description: First, place the outer ring 100 on the first guide rail 11 and the inner ring 101 on the second guide rail 12, so that the inner ring 101 and the outer ring 100 are on the conveyor belt and are transferred under the operation of the driving motor 13. When the outer ring 100 and the inner ring 101 are transferred to the through-hole position, they stop. At this time, the lifting cylinder 14 lifts the tray 141 through the through-hole, and the positioning block 142 on the tray 141 locks the position of the inner ring 101 and transfers it to the first guide rail 11. At this time, under the action of the pressing cylinder 21, the frame 22 makes the positioning rod 226 approach the positioning block 142, so that the positioning rod 226 is in the groove, and the spring 224 absorbs the force received by the positioning rod 226.

At this time, the inner ring 101 and the outer ring 100 form an area for placing the balls 102. Then, the cylinder drives the clamping cylinder 32 to move to cover the area for placing the balls 102, and controls the clamping cylinder 32 to release the conduit 225, so that the balls 102 transmitted by the conduit 225 fall into the designated area. Then, reverse the servo motor. Under the movement of the clamping force to push the outer ring 100, the inner ring 101 and the outer ring 100 are in the same center position, thereby completing the combination of the outer ring 100, the inner ring 101 and the balls 102.
