[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are mainly composed of outer rings, inner rings, rollers, and cages. Cages (i.e., bearing cages, also known as bearing retainers) refer to bearing parts that partially wrap all or part of the rolling elements and move with them. They are used to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearings. During the production process of the cage, the upper and lower cages need to be riveted together by rivets. Therefore, it is necessary to design a bearing cage rivet detection machine to detect them.

[0005] By adopting this structure, the bearing retainer is placed in the placement groove of the placement seat, the driving shaft is driven to rotate by the power mechanism, the driving shaft drives the main sprocket to rotate, the main sprocket drives the chain to rotate, the chain drives the installation bar to move, so that the placement seat is moved to the bottom of the lifting seat, the lifting seat is driven downward by the driving mechanism, and the lifting seat drives the positioning guide plate to move downward. Through the cooperation of the detection needle, the travel switch and the prompt light, it can be detected whether the rivet assembly at the bearing retainer is abnormal, and the detection is convenient.

[0006] The support track is a non-closed ring with a notch, and the non-closed ring includes an inclined introduction portion, a horizontal maintaining portion and an inclined lead-out portion.

[0007] With this structure, the horizontal holding part can keep the placement seat in a horizontal state, the inclined introduction part can switch the placement seat from a vertical state to a horizontal state, and the inclined lead-out part can switch the placement seat from a horizontal state to a vertical state. The notch can facilitate the bearing retainer to fall out of the placement seat after inspection.

[0008] The power mechanism includes a power motor, gear one and gear two. The power motor is fixed on the bottom plate, and the output shaft of the power motor is vertically downward. Gear one is fixed on the end of the output shaft of the power motor, and gear two is fixed on the driving shaft, and gear two is meshed with gear one.

[0009] With this structure, the power motor drives gear one to rotate, gear one meshes with gear two, and gear two drives the driving shaft to rotate, thereby making the driving shaft rotate.

[0014] A loading rack is fixed on the bottom plate, and a T-block is fixed on the loading rack. The T-block is detachably connected to the U-block, and a storage tube with a storage channel is connected to the U-block. An auxiliary notch is provided on the side of the lower end of the storage tube, and a fixing rod is installed at the auxiliary notch. A positioning shaft is rotatably installed on the fixing part, and a reset torsion spring is also provided between the positioning shaft and the fixing rod. The positioning shaft and the material control part are fixedly connected, and a stop block 1 is provided on the upper part of the material control part through a damping structure, a stop block 2 is installed in the middle part of the material control part, and a linkage block is installed at the lower part of the material control part.

[0015] By adopting this structure, the storage tube storing the bearing retainer is matched with the U-block and the T-block to be locked on the loading rack. As the placement seat gradually moves to the bottom of the storage tube, the elastic sheet of the placement seat acts on the linkage block to make the material control part swing, and the stop block 2 is separated from the bearing retainer at the bottom of the storage tube, and the bearing retainer enters the placement groove of the placement seat. At the same time, the stop block 1 abuts against the second to last bearing retainer at the bottom of the storage tube, thereby completing the automatic loading operation and making loading simple.

[0016] The damping structure includes an elastic bag, a working cylinder, a piston and a rigid liquid guiding tube. The elastic bag is installed on a fixed rod, and the linkage block can abut against the elastic bag. The working cylinder and the upper part of the material control piece are fixedly connected.

[0019] With this structure, when loading, the linkage block abuts against the elastic bag, pressing the liquid in the elastic bag into the working cylinder to move the piston; and after the elastic sheet is separated from the linkage block and the material control part is reset, the liquid in the working cylinder can slowly flow back into the elastic bag due to the action of the baffle group, so that the first material block can be reset first, and then the second material block can be reset, thereby preventing the bearing retainer in the material storage tube from accidentally falling out, and the use effect is good.
