Double face abrading machine

Abstract

The double side grinding machine comprises the sand wheel and the working piece deliver devices with the sand wheel composed of two main shafts fixed to two ring sand wheels of the main shaft coaxially, two sand wheels rotating independently without speed tuning, oblique adjustment and axial adjustment device set on two main shafts independently, the work piece delivery device composed of work piece fixed part and the displacement mechanism, lower of the part having clamps with installation slots with locking device at the edge of the slot, lower part fixed with the linking arm and fixed on the working platform, top being floating pressing head and connected with one end of the support arm, central axis of the support arm connected to the work platform, the other end of the support platform connected to the press head oil cylinder, working platform pushed by the displacement oil tank moving in the direction vertical to the central line of the main shaft and repeatedly moving back and forth between two sand wheels, and moving oil cylinder, alighting oil tank moving back and forth according to the control of the hydraulic system.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a double-sided grinding machine for precision grinding two symmetrical sides of sheet workpieces such as compressor blades and sliding vanes. Background technique [0002] In the existing grinding machine tools, if two symmetrical planes are processed on the workpiece, generally the way of clamping or adsorption is adopted, and one plane is processed first, and then the other plane is processed, or a single workpiece is corrected and clamped, and then sent to the Grinding in the gap between the two ends of the double grinding wheel, the process is long, the production efficiency is low, and it is extremely difficult to ensure the position accuracy of the ground surface corresponding to other surfaces, and the workpiece size cannot meet the accuracy requirements. In addition, these methods are not suitable for the processing of thinner sheet-like workpieces. Contents of the invention [00...
