On-line cylinder core adjusting machine: The main content of the air conditioning compressor cylinder and upper bearing components for core adjustment, assembly (including screw tightening and screw loosening) operations. ( Am ax By measuring the high point size of the crankshaft and roller combination, as well as the inner diameter size of the cylinder and upper bearing combination, the core adjustment is measured by means of gas-electric conversion, the clearance is adjusted to the specification range, and the screw is tightened according to the specified torque to realize the assembly of the cylinder and upper bearing. The main implementation actions are:Amax"Put the workpiece in-Start the machine-Measured peak-Take out the work-Core shifter "tooling disk inflow-Reserve for descent-Job clamping-Core adjusting-Self-tightening screw-Restore to original position-Tooling plate-rise-Tooling disc outflow ".
