Comprehensive measuring instrument for magnetic head driving arm assemblies

The utility model relates to a comprehensive measuring instrument for magnetic head driving arm assemblies, comprising a laser measurement unit, an adjustment unit, an optical detection device, and a voice coil electric measurement circuit. The laser measurement unit is used for measuring the height, bending degree and winding degree of a magnetic head arm of a magnetic head driving arm assembly. The adjustment unit is used for adjusting the height of a magnetic head arm of a magnetic head driving arm assembly of which the height of the magnetic head arm is unqualified. The optical detection device is used for optically detecting the magnetic head arm punched hole size, magnetic head welding spot alignment and a magnetic head connector pin of a magnetic head driving arm assembly. The voice coil electric measurement circuit is used for measuring electric parameters and mechanical parameters of a magnetic head driving arm assembly. The comprehensive measuring instrument of the utility model has multiple functions, can quickly respond to test renewing and updating of new magnetic head products, is conducive to the maintenance of the production line, and improves the production efficiency, reduces the number of working personnel and lowers the cost of production.
