Regular L-shaped sliding plate applying linear motor driving

Abstract

The invention provides a regular L-shaped sliding plate applying linear motor driving, and the regular L-shaped sliding plate provided by the invention is used for supporting a cross beam. The regular L-shaped sliding plate is characterized in that a stand column of a sliding plate (1) forms a regular L shape with a bottom angle in front of the stand column; a bevel reinforcing structure is arranged at the corner of L; slide blocks (4) are respectively arranged on the front vertical face of the L-shaped sliding plate and the upper plane of the bottom edge of a right angle, and is combined with a guide rail (5) arranged on the cross beam (6) in a hanging arrangement mode; hydraulic brakes (3) are arranged in the middle parts of the sliding blocks (4) in parallel; a primary stage (2) of a linear motor is obliquely arranged on the corner slope structure of the sliding plate (1), and a secondary stage (7) of the linear motor is arranged on a lower slope of the cross beam; and the guide rail (5) is fixed on the front vertical face of the cross beam (6) and the bottom edge of an inner slope at the bottom of the same side of the front vertical face. The L-shaped sliding plate has the advantages that the linear motor is easily assembled, the electromagnetic force is eliminated, friction on the guide rail when the sliding plate moves in the Y direction is reduced, the rigidity of the sliding plate is greatly improved, and the like. By utilizing the L-shaped sliding plate, the Y-direction acceleration performance of a machine tool is improved, the drive loading of the machine tool is lightened, and the service lives of the guide rail and the linear motor are prolonged.

Description

technical field [0001] The invention relates to a slide plate structure of a high-speed gantry five-axis gantry machining center. Background technique [0002] Most of the traditional skateboard structures are straight or reverse L-shaped, and are driven by racks or leadscrews. When a linear motor is used, the strong electromagnetic attraction of the linear motor increases the deformation of the slide plate and increases the pressure between the slider and the guide rail, thereby increasing the friction force during the operation of the machine tool and reducing the acceleration performance and key of the machine tool. The service life of purchased parts. And in order to have the installation space for the linear motor, it is necessary to remove the reinforcing ribs in the middle part of the skateboard with a large area of ​​ribs, so that the rigidity of the skateboard is greatly reduced. Contents of the invention [0003] The object of the present invention is to provid...
