Abstract

The invention relates to a lateral screw rod air pressure support device, belonging to the technical field of machine tool fittings. The device is provided with a cylinder. A piston is arranged on the lower connecting plate. A piston rod of the cylinder penetrates through the lower connecting plate and is fixed with a guide sleeve of the upper connecting plate. A guide rod is arranged between the upper connecting plate and the lower connecting plate. The upper connecting plate can slide up and down using the guide rod as a guide, and a supporting plate is fixed with the upper connecting plate via a tray. The invention not only can solve the problems of large sagging deflection caused by the dead weight of the screw rod and the shake caused during the movement, but also has no influence on the effective stroke of the screw rod, and has simple structure, safety and reliability.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to an air pressure support device for a transverse 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 drooping deflection caused by the self-weight of the screw 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 excessively long horizontal screw rod of the machine tool, large sagging deflection caused by the self-weight of the screw rod and vibration caused by the movement process, the present invention provides a horizontal screw rod air pressure supp...
