Description
Technical Field
[0001] The utility model relates to the technical field of roller processing and feeding, in particular to a roller feeding device for a ball base surface grinder. Background Art
[0002] Roller bearings are a type of rolling bearings and are one of the components widely used in modern machinery. They rely on rolling contact between main components to support rotating parts. Most roller bearings are now standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and easy selection. When processing the rollers in roller bearings, the rollers are transported to the processing station through the feeding mechanism, and then polished by the processing mechanism of the grinder.
[0003] By comparing with the existing technologies in related fields, it can be seen that when the existing feeding device is feeding, the roller is directly transported to the processing station through the material guide channel. The roller is very likely to be blocked at the processing station, causing a backlog of rollers, affecting the feeding efficiency of the rollers and slowing down the efficiency of roller processing. Utility Model Content
[0004] The purpose of the utility model is to provide a roller feeding device for a ball-based surface grinder in order to solve the above-mentioned problem.
[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] A roller feeding device for a ball-based surface grinding machine comprises a base, a guide plate and a turntable are installed on the base, the guide plate is located at the outer circle of the turntable, a feed trough, a roller limiting assembly and a main shaft are installed on the turntable, the feed trough and the roller limiting assembly are located at both ends of the guide plate, a pusher unit and a support are installed on the main shaft, a driving unit is installed on the support, the driving unit is connected to the pusher unit, the pusher unit is slidably connected to the feed trough and the guide plate, the feed trough is connected to an external feeding assembly, the roller limiting assembly is located at a grinding processing position of an external grinder, the external feeding assembly transports the roller into the feed trough, the roller is transported to the turntable through the feed trough, the pusher unit is driven by the driving unit to push the roller, the guide plate is used to guide the roller, and the roller is limited by the roller limiting assembly, so that the roller enters the processing position for grinding;
[0007] The pushing unit includes an arc swing arm, which is rotatably installed on the main shaft, and the arc swing arm is slidably connected to the feed trough, the guide plate and the turntable. A driving arm is installed on the arc swing arm, and the driving arm is connected to the driving unit.

The driving unit drives the arc swing arm to rotate in the opposite direction around the main shaft through the driving arm, and the arc swing arm drives the rollers to move along the guide plate, so that the arc swing arm After the roller is moved to the front limit position, the roller continues to move under the action of inertia, so that the roller moves to the processing station of the roller limit assembly. At the same time, the arc swing arm makes the guide plate contact the roller limit assembly through the adjusting assembly and the baffle, and the guide plate is buffered by the buffer assembly. After the arc swing arm moves to the front limit position, the arc swing arm moves in the opposite direction to the rear limit position, and the next roller enters and waits for feeding again, thereby completing the intermittent automatic feeding of the roller.
