Description

Technical Field

[0001] The utility model relates to the technical field of bearing feeding, in particular to a bearing feeding device. Background Technique

[0002] The motor bearing is one of the key components of the motor. Its main function is to support the motor spindle so that the motor (rotor) can rotate smoothly. In the prior art, usually, the bearings to be fed are placed on the surface of the conveyor belt one by one, and then the bearings are conveyed by the conveyor belt to the area where the gripper can grip and are gripped by the gripper. The space utilization rate of feeding in this way is relatively low.

[0003] A feeding device is disclosed in the publication number CN202311756797. When feeding the bearings, the bearings to be fed are put on the material rods. Multiple bearings can be placed on multiple material rods each time. Subsequently, the material rods with multiple groups of bearings are placed inside the fixed frame. Then, the top ends of multiple telescopic rods are connected and fixed to the connecting frame through the fixed rods. During the bearing feeding process, the second cylinder is started to retract, and the expansion mechanism is used to expand and fix the inner side of the second-to-last bearing at the bottom end of the material rod. Then, the first cylinder is started to retract to lift the lifting frame, so as to lift multiple groups of material rods below. Since the inner side of the second-to-last bearing at the bottom end of the material rod is expanded and fixed, the upper bearings are lifted together, and the bottom end of the material rod is moved out from the inner side of the lowest bearing. At this time, multiple groups of the lowest bearings are synchronously pushed out to the conveying frame, and then the operation is repeated until all the bearings on the material rod are pushed out. The multiple groups of bearings are conveyed and fed through the conveying frame at the same time. The space utilization rate of this device for feeding is relatively low, and it cannot meet the function of feeding single bearings to the processing equipment in sequence during the production process.

The bearing carrier D6 is arranged in contact with the side wall of the bottom plate A1 away from the bearing discharging mechanism A0.

[0042] The working process of the present utility model is as follows:

[0043] Install bearings B6 on all the stringing columns B5. Starting from the first stringing column B5, when the sensor B8 below the first stringing column B5 senses that there is a bearing B6 in the corresponding material cavity of the first stringing column B5, the output end of the pushing mechanism cylinder C5 corresponding to the first stringing column B5 extends along the longitudinal slideway direction, pushing the bearing B6 in the material cavity into the transverse slideway. Then, the output shaft of the bearing discharging cylinder A9 drives the cylinder floating block A7 to move horizontally, thereby driving the slider connecting plate A6 to move horizontally, so that the feeding push plate A3 moves horizontally to push the bearing B6 along the transverse slideway into the top surface of the bearing carrier D6. At this time, after the miniature opposed sensor D7 detects that there is a bearing B6 on the top surface of the bearing carrier D6, the output end of the transverse cylinder D5 drives the feeding cylinder connecting head D13 to move horizontally, thereby driving the feeding moving plate D1 to move horizontally, so that the bearing carrier D6 moves horizontally to the in-place position. After reaching the in-place position, the output shaft of the vertical cylinder D16 moves upward, thereby lifting the first floating joint D18 and then lifting the positioning constraint table D19, so that the bearing B6 on the positioning constraint table D19 is lifted out to complete the feeding operation. Sequentially, the second bearing B6 from bottom to top on the first stringing column B5 falls into the material cavity under the action of gravity, and the feeding operation is completed according to the above process. Only after all the bearings B6 on the previous stringing column B5 are pushed out, that is, when the sensor B8 directly below the first stringing column B5 does not detect the bearing B6, will the pushing mechanism cylinder C5 corresponding to the next stringing column B5 detect the presence or absence of the bearing B6 and perform the pushing action.
