Description

Gantry Y-axis hard-rail pull-up support mechanism

The invention relates to the gantry machine tool, in particular to the displacement support mechanism of the working machine base relative to the beam (Y-axis), and provides the full support of the working machine seat when the relative beam is displaced, and improves the sag of the previous screw-driven working machine seat relative to the beam displacement. And the drooping phenomenon is easy to derive the transmission mechanism gradually heating deformation defects, and thus will not affect the processing accuracy of the gantry processing machine.

The gantry machine system includes an organic seat, and a bed base is arranged on the machine base. The machine base is provided with a slide rail for the displacement of the bed relative to the base (defined as the X-axis), and the door frame is provided on the base. The column and the column include a column on both sides of the bed and a beam on the bed. The beam is provided with a slide for the displacement of the working frame (defined as the Y axis), and is uploaded on the working frame. Set the working head of the cutting spindle.

In order to solve the vertical design of the beam of the general gantry processing machine and the working machine base (with the working machine head), the heavy load of the working machine base (with the working machine head) is too large, resulting in the working machine base (with the working machine head). The problem of inaccurate positioning and wasted motor power is therefore a result of the development of a gantry machine with a hatched back beam structure. However, the conventional gantry Y-axis (displacement of the working machine seat along the beam) does not have proper supporting means, no matter how long the radial transmission mechanism is, resulting in sagging of the transmission component (generally screw drive), resulting in no transmission. Moving in the same center line, it is easy to produce temperature rise, thermal expansion, structural thermal deformation of the relevant transmission components and damage of the overloaded bearing, which in turn affects the machining accuracy of the gantry processing machine.

In view of this, the inventor of the present invention uses a lot of time to invest in research in order to improve the sag phenomenon of the Y-axis transmission component (screw) of the above-mentioned gantry processing machine, and the easy rise of temperature rise, deformation, and damage of the overloaded bearing.
