The invention discloses a honing head lifting device with a relatively high automation degree. The honing head lifting device is mounted on a main spindle box of a horizontal honing machine, wherein the main spindle box is supported in a sliding manner through a guide rail arranged on a lathe bed; a main spindle on the main spindle box is connected with a honing head through a universal joint; the honing head lifting device comprises a transverse beam; guide columns are arranged at front and rear ends of the transverse beam respectively; the guide columns are movably arranged on a guide seat on a box body of the main spindle box in a penetrating manner and stretches into the box body of the main spindle box; the main spindle box is internally provided with an oil cylinder for driving the transverse beam to move horizontally; a supporting plate is arranged on the transverse beam; a groove for supporting the honing head is formed on the supporting plate; the surface, which is in contact with the outer circular surface of the honing head, of the groove is arc-shaped; travel switches are arranged at the left end of the transverse beam and the right end of the guide rail on the lathe bed respectively. The honing head lifting device disclosed by the invention can be used for automatically lifting the honing head to the horizontal state so that the problem that the honing head needs to be manually centralized in a machining process is solved; after the honing head is safely conveyed into a hole to be machined of a workpiece through the supporting plate, the supporting plate can be automatically released from the honing head and the work of the honing head is not influenced.
