Problems solved by technology

[0003] However, the above-mentioned gantry has the following disadvantages: it is affected by the processing accuracy and installation accuracy, and it is difficult to adjust the perpendicularity between the beam and the two Y directions. During operation, internal stress will be generated between the systems, which will increase the friction of the guiding mechanism and affect the life of the guiding mechanism

Embodiment Construction

[0020] Please refer to the attached figure 1 to attach Figure 5 As shown, the present invention is a flexible double-drive gantry structure, which is composed of an X-direction beam 1, a support frame I2, a support frame II3, a guide drive assembly I4, a guide drive assembly II5, and a base 6.

[0021] Wherein, the support frame I2 and the support frame II3 are respectively fixedly installed on the guide drive assembly I4 and the guide drive assembly II5 which are arranged parallel to each other. An X-direction guiding mechanism 21 capable of moving along the X direction and a rotating mechanism I22 capable of rotating along the Z direction are provided on the support frame I2; the rotating mechanism I22 is installed on the X-directing mechanism 21. A rotating mechanism II31 capable of rotating along the Z direction is provided on the support frame II3.

[0022] The X-direction beam 1 is installed on the supporting frame I2 and the supporting frame II arranged parallel to e...

Abstract

The invention relates to a flexible double-drive gantry structure. The flexible double-drive gantry structure comprises an X-direction cross beam, a support frame I, a support frame II, a guide driving assembly I, a guide driving assembly II and a base, wherein the X-direction cross beam is arranged on the support frame I and the support frame II which are arranged in parallel to each other; the support frame I and the support frame II are separately and fixedly arranged on the guide driving assembly I and the guide driving assembly II which are arranged in parallel to each other; and the guide driving assembly I and the guide driving assembly II are arranged on the base. According to the flexible double-drive gantry structure disclosed by the invention, the stability of the structure is high, and the perpendicularity errors between the X-direction cross beam and Y-direction guide driving assemblies caused by mounting and processing can be effectively eliminated; an internal stress inside the system caused by greater parallelism errors between the Y-direction guide driving assemblies and the corresponding guide driving assemblies due to processing and mounting can be effectively eliminated; and an inclined angle of the X-direction cross beam relative to the X direction can be changed so as to adapt to the inclined angle change of processed workpieces.

Description

technical field [0001] The invention relates to a composition structure of a machine tool, in particular to a flexible double-drive gantry structure, which belongs to the technical field of bed frames. Background technique [0002] The traditional gantry usually adopts a bed frame structure with two vertical and one horizontal. The beam is rigidly fixed on two Y-direction guide mechanisms. The beam cannot move along the X-axis and cannot rotate along the Z-axis. The beam can only move in the Y-direction. [0003] However, the above-mentioned gantry has the following disadvantages: it is affected by the processing accuracy and installation accuracy, and it is difficult to adjust the perpendicularity between the beam and the two Y directions. During operation, internal stress will be generated between the systems, which will increase the friction of the guiding mechanism and affect the life of the guiding mechanism. [0004] Therefore, in order to solve the above technical pr...
