Abrégé

Disclosed is a reciprocating servo control device for the mainshaft of a honing machine. The device comprises a bed body, a mainshaft mechanism of the honing machine mounted on the bed body, a driving system for hydraulic reverse and a control system. The driving system for hydraulic reverse comprises a mainshaft hydraulic cylinder (10) and a mechanical-hydraulic servo valve for controlling the reciprocation of the mainshaft hydraulic cylinder (10). The valve body (12) of the mechanical-hydraulic servo valve is connected to the piston rod (11) of the mainshaft hydraulic cylinder (10) through a connecting mechanism. One end of a connecting member (5) is connected to the spool (14) of the mechanical-hydraulic servo valve, and the other end is connected to a shifting mechanism which is controlled by a servo-drive control system. The reciprocating servo control device for the mainshaft of the honing machine utilizes the position closed-loop of a numerical control mechanism and the hydraulic position closed-loop composed of the linear mechanical-hydraulic servo valve to realize the numerical control of speeds, positions and reversing of the mainshaft hydraulic cylinder (10) of the honing machine, thus simple structure, reliable control, low price and easy adjustment, operation and maintenance can be realized.
