Description

Technical Field

[0001] The utility model relates to the field of bearing processing, especially the technical field of bearing inner ring feeding, and specifically provides an automatic bearing inner ring feeding module. Background Art

[0002] A rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring of the bearing is fitted with the shaft and rotates together with the shaft. In the prior art, after batch processing of each groove of the bearing inner ring is completed, it needs to be transported to the assembly process. In the assembly process, technicians need to place the bearing inner rings to be fed one by one on the surface of the conveyor belt, and then the conveyor belt transports the bearings to the assembly mechanical module. This requires continuous mechanical movement by technicians, resulting in low processing efficiency and high manual labor intensity.

[0003] There is a bearing feeding machine disclosed in the patent publication No. CN206780016U. When this device is used, workers need to place the bearings on the feeding rail, and then start the air cylinder, so that the push block pushes the bearings placed on the feeding rail into the feeding rail.

[0045] The present utility model provides an automatic loading module for bearing inner rings, which is used in the automatic loading process of bearing inner rings. The present utility model does not limit the type of bearing inner rings, but the installation frame 1, the material stacking table 2, the pushing cylinder 3, the automatic loading module 4 and the conveying track 5 are particularly suitable for the automatic loading design of bearing inner rings.

[0046] Generally speaking, the automatic loading module for bearing inner rings proposed by the present utility model mainly includes: the installation frame 1, the material stacking table 2, the pushing cylinder 3, the automatic loading module 4 and the conveying track 5. Among them, reference can be made to Figure 1 , which shows the layout relationship of the installation frame 1, the material stacking table 2, the pushing cylinder 3, the automatic loading module 4 and the conveying track 5.

[0047] When using the automatic loading module for bearing inner rings proposed by the present utility model, technicians need to align the V-shaped groove 21 on the side far from the pushing cylinder 3 in the material stacking table 2 with the push plate 46 first, and then stack the bearing inner rings in all the V-shaped grooves 21. The lead screw stepping motor 44 is started to control the push plate 46 to step forward along the positioning optical rod 45 towards the conveying track 5, and send the bearing inner rings into the conveying track 5, so as to convey the bearing inner rings to the assembly area, improve work efficiency and reduce the labor intensity of technicians.

[0048] It should also be noted that when the laser sensor 53 detects that there is an inner bearing ring in the conveying track 5 area in the lower area, the lead screw stepping motor 44 stops moving. When the laser sensor 53 detects that there is no inner bearing ring in the conveying track 5 area in the lower area, it will control the lead screw stepping motor 44 to start. When the push plate 46 abuts against the stop block 48, the inner bearing ring in this V-shaped groove 21 has been emptied. The push plate 46 returns to the origin, and the pushing cylinder 3 pushes the material loading table 2 to move forward a specific distance along the positioning guide rail 11, moving the full V-shaped groove 21 in the next row to below the push plate 46. When the inner bearing rings in the 3-4 V-shaped grooves 21 in the material loading table 2 are emptied, the technician can start replenishing the material. When the inner bearing ring in the V-shaped groove 21 on the side close to the pushing cylinder 3 is also emptied, the pushing cylinder 3 will drive the material loading table 2 back to its original position to perform step feeding on the inner bearing ring in the V-shaped groove 21 that has been replenished with material before. At this time, the technician can replenish the emptied V-shaped groove 21 on the side close to the pushing cylinder 3, and continuous feeding can be carried out without interruption.

[0049] The above-mentioned mounting frame 1 is a rectangular parallelepiped frame. The left side of the top of the mounting frame 1 is provided with a positioning guide rail 11 by welding, and the right side of the top of the mounting frame 1 is provided with a heightening slider 12 by welding.

The lead screw stepping motor 44 controls the rotation of the lead screw 42 to make the sliding block 43 move back and forth along the lead screw 42. The positioning optical rod 45 is arranged directly above the lead screw 42. The left and right sides of the positioning optical rod 45 are clamped on the tops of the pair of L-shaped mounting frames 41. The top of the push plate 46 is respectively sleeved on the lead screw 42 and the positioning optical rod 45. The bottom end of the push plate 46 extends vertically downward towards the material stacking table 2.
