A reciprocating servo control device for a mainshaft of a honing machine includes a bed body, a mainshaft mechanism of the honing machine mounted on the bed body, a driving system for hydraulic reversing and a control system, where the driving system for hydraulic reversing of the honing machine includes a mainshaft hydraulic cylinder (10) and a mechanical-hydraulic servo valve for controlling the reciprocation of the mainshaft hydraulic cylinder (10), a valve body (12) of the mechanical-hydraulic servo valve is connected to a piston rod (11) of the mainshaft hydraulic cylinder (10) via a connecting mechanism, one end of a connecting member (5) is connected to a spool (14) of the mechanical-hydraulic servo valve, and the other end is connected to a converting mechanism which is controlled by a servo driving and control system. The reciprocating servo control device for a mainshaft of a honing machine adopts a mechanical position closed-loop with numerical control and a hydraulic position closed-loop composed of a linear mechanical-hydraulic servo valve, to achieve numerical control of speed, position and reversing of the mainshaft hydraulic cylinder (10) of the honing machine, thus a simple structure, reliable control, low price and easy adjustment, operation and maintenance can be realized. |
