Problems solved by technology

[0002] The gantry mechanism is a widely used driving device at present. The commonly used gantry equipment has a double-drive gantry. The traditional double-drive gantry is generally driven by a servo motor plus a screw. The driving length of this driving method is limited, and in There is a mechanical gap in the driving process, which can easily lead to transmission errors. At the same time, after frictional contact, the driving accuracy will be low, and the driving operation cannot be performed accurately.

Embodiment Construction

[0025] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0026] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a double-drive gantry structure includes: a frame 1, a double-drive platform 2 is arranged on the frame 1; a Y-axis drive module, the number of Y-axis drive modules is two groups and parallel to the center of the double-drive platform 2 Symmetrical, the Y-axis drive module includes a Y-axis stator magnetic track 8 and a Y-axis mover 9. The Y-axis stator magnetic track 8 includes a plurality of Y-axis stators connected in sequence, and the Y-axis mover 9 can be opposite to the Y-axis stator magnetic track 8. For sliding, the Y-axis mover 9 is provided with a Y-axis senso...

Abstract

The invention discloses a double-drive gantry structure. The double-drive gantry structure comprises a frame, Y-axle driving modules and an X-axle driving module, wherein the frame is provided with adouble-drive platform; two sets of the Y-axle driving modules are provided, and are symmetrically arranged about the center of the double-drive platform in parallel; the Y-axle driving modules comprise Y-axle stator magnetic rails and Y-axle movers; the Y-axle stator magnetic rails comprise multiple Y-axle stators connected in sequence; the Y-axle movers are provided with Y-axle sensors; the X-axle driving module is positioned between the two Y-axle driving modules, and is perpendicular to the Y-axle driving modules; the X-axle driving module can move relative to the Y-axle driving modules, and comprises an X-axle stator magnetic rail and an X-axle mover; and the X-axle stator magnetic rail comprises multiple X-axle stators connected in sequence; and the X-axle sensor is arranged on the X-axle mover. The double-drive gantry structure is free of limitation on the driving length, free of wear and free of transmission errors, and guarantees the driving precision.

Description

technical field [0001] The invention belongs to the technical field of driving equipment, in particular to a double-drive gantry structure. Background technique [0002] The gantry mechanism is a widely used driving device at present. The commonly used gantry equipment includes double-drive gantry. The traditional double-drive gantry is generally driven by a servo motor plus a screw. The driving length of this driving method is limited, and in There is a mechanical gap in the driving process, which easily leads to transmission errors. At the same time, after frictional contact, the driving accuracy will be low, and the driving operation cannot be performed accurately. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides a double-drive gantry structure with unlimited driving length, no wear, no transmission error and guaranteed driving precision. [0004] In order to achieve the above object, the technical solution adop...
