Pneumatic control system for roller crown superfinishing machine
2 after the automatic pressure relief and other characteristics, can better meet the requirements of ultra-fine process. The working principle of the machine's pneumatic system is 1. The gas thus increases the service life of the bearing by 12 times. The maximum working pressure of the moving system is 3, and the compressed air entering the machine tool is first filtered and pressure-regulated and atomized by the pneumatic coupling. The actual number of cylinders used is determined according to the processing requirements of the specific workpiece. The cylinder is mounted on the dovetail rail of the oscillating head of the machine tool, and the manual reversing valve directly connected to the cylinder is connected to the compressed air to control the up and down movement; when the cylinder moves downward, the oil stone clamped on the piston rod of the cylinder is pressed against the workpiece surface. And maintain constant pressure. The size of the jade force is caused by the breakage of each of the strikers or the shortness of the oil stone according to the process requirement of the addition of 1 to cause the stone clip to directly contact the workpiece or the guide roller. Work, the neodymium reversing valve is energized. Push the valve handle of each manual reversing valve inward. At this time, the 1 and 2 channels of the pneumatic circuit are disconnected, and the compressor is manually reversing the valve chamber without a rod chamber through the 1 way pressure reducing valve. The cylinder is connected to a rock. Contact the workpiece. The cylinder has air in the rod cavity through the manual reversing valve 5 cavity one-way throttle valve electromagnetic reversing valve into the atmosphere. The size of the one-way throttle valve should be adjusted appropriately to prevent the impact of the oil stone on the workpiece; when it is necessary to replace the oil stone or adjust, pull the manual reversing valve stem outward to the original position. at this time. The cylinder has no rod cavity and manual change 4 valve, the cavity is connected. The compressed air is introduced into the atmosphere through the vent factory, the pressure is released, and the cylinder has a rod cavity and a manual reversing valve cavity to be connected to the compressed air, the cylinder is ascending, the oil stone is lifted, and the workpiece is quickly returned; if the machine is malfunctioning or Power off, the electromagnetic reversing valve is de-energized, the gas path is connected to the 1st and 2nd channels, and the compressed air is controlled by the 2-way one-way throttle network to control the gas path + the manual reversing valve cavity, and the valve stem is ejected outwards, returning In the original position, the cylinder is up and the oil stone is lifted automatically. The pneumatic system has a simple structure. The action is smooth. Meet the process performance requirements of the machine tool. It is only the design of the manual reversing valve and the cylinder body. Also used by the standard method of the standard electromagnetic reversing valve and standard cylinder editing 1 Ying Hui 1 this content summary Jiang Xingqi, Ma Jiayu, Fan Guzhen. Calculation of minimum preload load for high speed precision angular contact ball bearings. Bearing. 2,01614 improves spindle rigidity and rotation accuracy. Control the rolling and rotation of the rolling elements. A predetermined preload load shall be applied to the high speed precision angular contact ball bearing. Improper preloading increases the bearing heat. Reduce the fatigue life of the bearing and affect the rotational speed of the spindle. It is important to choose the appropriate preload according to the requirements of the machine spindle. Based on the analysis of the force of high-speed precision angular contact ball bearing steel ball, the minimum preloading force that should be applied when the ball does not produce gyro sliding in the channel is given.
