Embodiment Construction

[0017] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0018] The present invention is an improvement to the prior art - VMC2000 CNC gantry boring and milling machine and machining center, which is symmetrically located on both sides of the 30° inclined guide rail where the Y-axis carriage 1 and the beam 5 cooperate. The present invention includes a Y-axis carriage 1 , a beam 5 , a pressing plate 3 and a wedge 4 . The pressure plate 3 is arranged on the lower side of the lower guide rail surface 2 of the Y-axis carriage and the lower guide rail surface 6 of the crossbeam, and a notch groove with an "L" shape in section is provided on the pressure plate 3 . The pressure plate 3 is closely attached to the lower guide rail surface 2 of the Y-axis carriage. The notch of the pressure plate 3 is set on the lower side of the lower guide rail surface 6 of the beam. In the notch groove of the pressure plate 3....

Abstract

The present invention relates to the improvement of available VMC2000 numerically controlled planer boring / milling machine, and is especially guide rail structure for Y-axis carriage and cross beam of numerically controlled planer boring / milling machine. The present invention includes Y-axis carriage, cross beam and clamping plate, and features the wedge between the lower cross beam rail and the clamping plate, and the adjustable relative position of the wedge with a regulator. The present invention has the advantages of convenient regulation of the gap between the clamping plate and the lower rail plane of the Y axis with screw, omitting the corresponding repair, easy machine assembling to reach required precision.

Description

technical field [0001] The invention relates to a numerical control machine tool, in particular to a guide rail structure of a Y-axis carriage and a beam of a numerical control gantry boring and milling machine. Background technique [0002] The CNC gantry boring and milling machine adopts the worktable movement, the gantry fixed beam frame structure, the X-axis worktable moves horizontally, the Y-axis carriage moves horizontally on the beam, and the Z-axis ram-type spindle head moves vertically on the carriage. The Y-axis adopts a 30° inclined guide rail to improve the force performance and ensure good rigidity and precision retention of the whole machine. The guide rail structure of the Y-axis carriage and the beam of the CNC gantry boring and milling machine includes the Y-axis carriage, the beam and the pressure plate, which are located on both sides of the 30° inclined guide rail that the Y-axis carriage and the beam match. [0003] At present, the lower guide rail str...
