They are heavy and tightly arranged, resulting in a large overall mass and high cost. Moreover, when the gravity of the gantry worktable itself cannot be dispersed to the support positions on both sides, the middle position is prone to sag and deform due to its own weight, causing the workpiece placed on the gantry worktable for processing to be affected by the deformation. It is even necessary to repeatedly adjust the processing procedure of the workpiece according to the deformation amount of the gantry worktable at that time, which not only affects the processing accuracy, but also greatly increases the production cost.

[0019] The present utility model will be further described in conjunction with the drawings and specific embodiments.

[0020] Embodiment 1

[0021] Referring to Figures 2 to 4 as shown, Embodiment 1 provides a support structure of a gantry workbench (hereinafter referred to as the support structure) and is used as a loading platform for workpieces on a machine tool.

[0022] The support structure of this embodiment includes a workbench body 1 with a tabletop 11. Specifically, when processing a workpiece, the tabletop 11 is arranged upward, and the workpiece moves on the tabletop 11.

[0023] The bottom side of the workbench body 1 facing away from the tabletop 11 has an arched groove 13. The groove wall of the arched groove 13 forms an arched support member. Both ends of the arched support member are respectively provided with support platforms 14 for bearing loads, and the support platforms 14 are enclosed by the outer edge of the workbench body 1. The arched support member is used to convert the vertical load it receives into an axial load and distribute it to both sides of the arched support member, so as to disperse the vertical load, so that the workbench body 1 has an arched structure and makes full use of the compressive resistance of the arched support member, which is beneficial to improving the maximum load that the gantry workbench can bear and also improving the structural rigidity of the workbench body 1.

[0024] In this embodiment, the workbench body 1 is square, the arched support member is arranged along the width direction of the workbench body 1, and sliders can be installed on the support platforms 14 and slidably assembled on the frame of the processing machine tool to ensure that the gantry workbench is used as a moving part.

[0025] During the workpiece processing, since the processing machine tool itself will generate large vibrations, the arched structure of this embodiment will transfer the vibrations to both sides more efficiently, so as to effectively reduce the resonance formed during the operation of the processing machine tool, and further ensure the processing accuracy and reduce the noise pollution.

[0026] By converting the vertical load received by the arched support member into an axial load and distributing it to the support platforms 14 on both sides of the arched support member, the vertical load is dispersed, so as to effectively reduce the probability of sagging and deformation at the middle position due to its own weight, thereby ensuring the processing accuracy and significantly reducing the production cost, and also improving the structural rigidity and strong vibration stability of the workbench body 1.

[0027] In another preferred embodiment, arched ribs 12 are provided on the groove wall of the arched groove 13.

[0028] The arched ribs 12 span the middle area of the workbench body 1, and both ends of the arched groove 13 in the width direction are respectively spaced from the long side 16 of the workbench body 1.

[0029] More specifically, both ends of the arched groove 13 are symmetrically arranged on both sides of the center line of the workbench body 1 in the width direction, so that a large space and distance can be spanned. At the same time, the two support platforms 14 are also symmetrically arranged on both sides of the center line of the workbench body 1 in the width direction, which is especially suitable for large-span gantry workbenches. The middle arch formed by the arched groove 13 can reduce the material usage, so as to achieve the purpose of reducing the material cost while ensuring the structural rigidity of the entire workbench body 1.

[0030] Further preferably, support ribs 15 are respectively arranged between the support table 14 and the long side 16 of the two workbench bodies 1, and an inclined surface 151 for dispersing the load is arranged on the bottom side of the support rib 15 facing away from the tabletop 11.

[0031] Through the inclined surface 151 of the support rib 15, the vertical load in the area where the support rib 15 is located is transferred to the side of the support table 14, thereby ensuring that this place is not easily deformed.

[0032] Of course, in other embodiments, an arc surface for dispersing the load may also be arranged on the bottom side of the support rib 15 facing away from the tabletop 11.

[0033] Embodiment 2

[0034] Embodiment 2 provides a gantry workbench, which at least includes the support structure of the gantry workbench in Embodiment 1.

[0035] Although the present invention is specifically shown and introduced in combination with the preferred implementation embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
