Abstract

The invention discloses an oil pressure supporting device for a machine tool horizontal screw rod, which belongs to the field of machine tools. The oil pressure supporting device is provided with a hydraulic supporting device and is characterized in that the hydraulic supporting device is positioned in the middle of the screw rod; the top of the hydraulic supporting device is provided with a roller wheel for dragging and propping up the screw rod; when a screw base of a working platform approaches, a message is sent to an electromagnetic valve so that a piston rod of an oil cylinder drives the roller wheel to retract so as to allow the screw base to get across; and when the screw base gets across for a certain distance, a message is sent to the electromagnetic valve so that the piston rod of the oil cylinder drives the roller wheel to raise to drag and prop up the screw rod. The oil pressure supporting device not only can solve the problems of large sagging deflection caused by the deadweight of the screw rod and the jitter caused in the moving process, but also does not influence the effective stroke of the screw rod at all, has a simple structure, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of machine tools, and relates to a hydraulic support device for a horizontal screw rod of a machine tool. Background technique [0002] As we all know, when the machine tool has a large stroke and is driven by a horizontal screw, because the screw is too long, the sag deflection caused by the screw's own weight is very large. To solve this problem, machine tool manufacturers usually use the way of pre-tensioning the bearing at the end of the screw. To reduce the sagging deflection of the screw and improve the rigidity of the screw, but the effect is not obvious Affects movement accuracy. Contents of the invention [0003] In order to overcome the problems of excessive length of the horizontal screw rod of the machine tool, large drooping deflection caused by the self-weight of the screw rod, and vibration caused during the movement process, the invention provides a horizontal screw rod hydraulic support device. ...
