Claims

[Scope of Claim for Utility Model Registration] 1. In a crossrail height adjustment device for a machine tool in which a crossrail is mounted on a column so that it can be raised and lowered,
a hydraulic cylinder for raising and lowering the crossrail with respect to the column; a positioning means provided between the crossrail and the column and capable of being engaged and detached at each of the plurality of height positions of the crossrail; and the crossrail. a flow rate regulating valve for reducing the flow rate of pressure oil supplied to or discharged from the hydraulic cylinder when the cross rail is near the engagement position of the positioning means; and a clamp for tightening and fixing the cross rail to the column. A machine tool cross rail height adjustment device characterized by: 2. The crossrail of a machine tool according to claim 1, wherein the positioning means is configured to be capable of being automatically selectively operated in response to a signal from a detector that detects the position of the crossrail and a signal specifying the number of stages of the positioning means. Height adjustment device.
