A sliding seat device of a numerically controlled machining center

Abstract

The invention discloses a slide seat device of a numerically-controlled machining centre. The slide seat device comprises a fixed frame, a first shaft slide seat and a first shaft drive mechanism, wherein the fixed frame comprised a fixed bottom plate, and a first guide groove is arranged in the fixed bottom plate; the first shaft slide seat comprises a slide seat and a press plate; a fixed element extends downwards from one side of a first through groove; the press plate is fixed on the slide seat; the first shaft drive mechanism comprises a first servo motor, a first bearing plate, a first guide assembly, a first drive assembly and a first steel wire; a guide pin is fixed at the bottom of the fixed bottom plate, a stopping element is fixed at the bottom of the fixed plate, the stopping element comprises a stopping fixed plate and a stopping plate bent downwards from the stopping fixed plate; a waist-shaped groove is arranged in the stopping fixed plate; the guide pin penetrates through the waist-shaped groove; a screw penetrates through the waist-shaped groove and is fixed on the fixed bottom plate; and the stopping plate stops on the first steel wire. According to the invention, the movement of the first shaft slide seat is more stable, the guide performance is improved, and the movement of the first steel wire is more stable.

Description

technical field [0001] The invention relates to a numerical control machining center. Background technique [0002] The workbench device of existing numerical control milling machine comprises base, is arranged on the X-axis seat that slides on the base, and X-axis seat is driven by servo motor, screw mandrel and nut, is provided with Y-axis seat sliding on X-axis seat, and Y-axis seat Driven by servo motors, screw rods and nuts, the table device can only move in the X-axis and Y-axis, and it is difficult to process workpieces with complex curves. In addition, the above-mentioned X-axis seat and Y-axis seat are only guided by guide rails, and the guiding precision thereof is relatively low, and the movement stability is poor. Contents of the invention [0003] In order to make the movement of the sliding seat of the first axis more stable, improve the guiding performance, and make the movement of the first steel wire more stable, the present invention provides a sliding s...
