The invention belongs to the technical field of machinery, in particular relates to an automatic rotary locking air-flotation workbench of an axle grinder. The rotary locking air-flotation workbench specifically comprises a table surface servo automatic conicity-adjusting mechanism, four table surface locking mechanisms and a pneumatic device, wherein the table surface servo automatic conicity-adjusting mechanism is connected with an eccentric shaft through a servo motor so as to automatically adjust the conicity of the workbench; the table surface locking mechanisms are four hydraulic disc spring energy storage clamps, arranged at two ends of the table surface of the workbench and are used for finishing the locking and loosening action of the table surface; and the pneumatic device comprises six paths of air floatation points respectively arranged at the lateral sides of the workbench, and the friction between the upper table surface and the lower table surface is reduced by carryingout air flushing on the pneumatic device. When the automatic rotary locking air-flotation workbench is used for grinding axle-like parts, the grinding of excircles at two ends is finished just by once clamping, therefore, the time for turning and adjusting upper and lower workpiece is shortened, and the machining production of parts is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to an automatic rotary locking air-floating workbench of an axle grinder. Background technique [0002] With the continuous development of grinding machine manufacturing technology, the continuous improvement of CNC electronic technology, and the continuous improvement of the precision and production efficiency of processed parts, it is required that CNC grinding machines have a high degree of automation, high precision and high productivity. It has become a trend of CNC grinding machines at home and abroad. To meet the ever-increasing technical requirements for parts processing. Whether the special axle grinding machine can have a high-precision automatic table turning mechanism is one of the main factors that affect the machining accuracy of the entire axle grinding machine and improve production efficiency. The sensitivity of the micro-rotation cone adjustment of t...
