Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in the figure, the automatic drilling and reaming system for the rocker arm in the embodiment comprises an automatic feeding device, a drilling and reaming host machine and a rocker arm clamp.
Automatic feeding includes vibration dish and push mechanism. The vibration dish is including setting up limiting plate 5 that is used for injecing rocking arm spiral rising orbit on the spiral quotation, form the spiral spacing groove 6 that can only supply the single row rocking arm to pass through between limiting plate and the spiral quotation limit portion, and the bottom surface of spiral spacing groove outwards inclines from the entrance point of spiral spacing groove to the exit end of spiral spacing groove gradually. The rocker arms gradually move upwards along the surface of the spiral disc under the vibration of the vibration disc and are sequentially arranged after entering the spiral limiting grooves; because the bottom surface of the groove of the rocker arm is a plane, the stable posture can be kept only when the bottom surface of the groove of the rocker arm is contacted with the spiral disc surface of the vibration disc, and therefore, the bottom surface of the outer side of the groove of the rocker arm is leaned against the bottom surface of the spiral limiting groove when the rocker arm smoothly enters the spiral limiting groove in the vibration upward moving process. And because the bottom surface of the spiral limiting groove gradually inclines outwards from the inlet end of the spiral limiting groove to the outlet end of the spiral limiting groove, the rocker arm can gradually turn outwards in the moving process along the spiral limiting groove.
