Technical Field

[0001] The utility model relates to the technical field of transportation operations, in particular to a gantry machine tool with a movable platform. Background Art

[0002] Gantry machine tools are widely used in metal cutting, milling, drilling, and other processing applications. Their key features are their large machining range and robust structure. Traditional gantry machine tools often have fixed worktables, requiring frequent manual adjustments or repositioning of workpieces when machining different workpieces. This increases production time and labor costs, and can also lead to safety hazards caused by improper operation. Furthermore, the market lacks a device that can increase the machine's working range.

[0003] Therefore, it is necessary to improve the existing gantry machine tools to solve the problems of frequent manual adjustment of the workpiece position due to the fixed setting of the worktable and the small working range of the machine tools.

[0004] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0006] To achieve the above objectives, the present invention provides a platform movable gantry machine tool, comprising a gantry, a machining module mounted on the gantry, and a movable workbench located below the machining module;

[0007] The movable workbench includes a work surface, a straight guide rail located below the work surface, and a direct drive module that drives the work surface to reciprocate along the straight guide rail.

[0008] Optionally, the direct drive module includes a rack fixed to the top of the straight guide rail, a rotary drive mechanism installed at the bottom of the work table, and a gear driven by the rotary drive mechanism to roll along the rack.

[0014] Optionally, the reinforcement assembly includes a plurality of transverse portions arranged perpendicular to the length direction of the rectangular frame, and an inclined portion is provided between two adjacent transverse portions.

[0015] Optionally, the machining module includes at least one of a milling cutter, a drill bit, a grinding head, and a cutter.

[0016] The beneficial effects of the present invention are: providing a platform-movable gantry machine tool, in which the direct drive module can drive the work table to reciprocate along the straight guide rail to adjust the position of the work table. On the one hand, the position of the work table can be adjusted to thereby adjust the position of the workpiece, thereby realizing automatic positioning of the workpiece and avoiding manual operation; on the other hand, the position of the work table can be adjusted to thereby adjust the working range of the machine tool, thereby widening the operating range of the machine tool while keeping the actual area of ​​the work table unchanged.

[0034] See also Figure 1 The utility model provides a platform movable gantry machine tool, comprising a gantry 1, a machining module 2 mounted on the gantry 1, and a movable workbench 3 located below the machining module 2;

[0035] Among them, see Figure 2 and Figure 3 The movable workbench 3 includes a work surface 301 , a straight guide rail 302 located below the work surface 301 , and a direct drive module 303 that drives the work surface 301 to reciprocate along the straight guide rail 302 .

[0036] Optionally, the machining module 2 includes at least one of a milling cutter, a drill bit, a grinding head, and a cutter, so as to perform corresponding machining operations such as milling, drilling, grinding, and cutting.

[0037] The platform-movable gantry machine tool provided in this embodiment has a direct drive module 303 that can drive the work table 301 to reciprocate along the straight guide rail 302 to adjust the position of the work table 301. On the one hand, the position of the workpiece can be adjusted by adjusting the position of the work table 301, thereby realizing automatic positioning of the workpiece and avoiding manual operation; on the other hand, the working range of the machine tool can be adjusted by adjusting the position of the work table 301, thereby widening the operating range of the machine tool while keeping the actual area of ​​the work table 301 unchanged.

[0038] Therefore, the platform-movable gantry machine tool provided by the present invention can effectively solve the problems of the existing gantry machine tool having a fixed working table 301 which requires frequent manual adjustment of the workpiece position and a small working range of the machine tool.

[0039] In this embodiment, the direct drive module 303 includes a rack 3031 fixed to the top of the straight guide rail 302, a rotary drive mechanism 3032 installed at the bottom of the work surface 301, and a gear driven by the rotary drive mechanism 3032 to roll along the rack 3031. The rotary drive mechanism 3032 drives the gear to rotate along the rack 3031, thereby causing the work surface 301 to move relative to the straight guide rail 302.

[0040] Optionally, the size of the straight guide rail 302 is larger than the size of the work surface 301, so that the work surface 301 can be fully and reliably supported at all positions.

[0041] In this embodiment, the work surface 301 is provided with a plurality of hydraulic clamping mechanisms 304 for holding the workpiece and a plurality of positioning columns 305 for positioning the workpiece. Furthermore, the end positions of the work surface 301 are provided with a plurality of supporting hydraulic cylinders 306 that can extend and retract in the vertical direction to support the workpiece.

[0042] When machining is required, the support hydraulic cylinder 306 extends upward, and after placing the workpiece onto the support hydraulic cylinder 306 and positioning column 305, the workpiece's position is fine-tuned to ensure it is positioned properly. Next, all hydraulic clamping mechanisms 304 are engaged to clamp the workpiece, completely positioning it on the work surface 301. The workpiece can then be subjected to machining operations such as milling, drilling, grinding, and cutting. Furthermore, during machining, if the workpiece's position needs to be adjusted, the rotary drive mechanism 3032 is activated to move the work surface 301.

[0043] In this embodiment, the straight guide rail 302 includes a rectangular frame 3021 and a reinforcement assembly positioned within the rectangular frame 3021. Optionally, the reinforcement assembly includes a plurality of transverse portions 3022 disposed perpendicular to the length of the rectangular frame 3021, with an inclined portion 3023 disposed between adjacent transverse portions 3022. The inclined portions 3023 can form a triangular support structure, thereby enhancing the structural stability of the rectangular frame 3021.

[0044] It should be noted that the linear drive mechanism mentioned in the present invention can be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or a motor-screw linear module, and the rotary drive mechanism 3032 mentioned can be a brushed motor, a brushless motor, or a rotary cylinder. The present invention does not limit the specific structural forms of the linear drive mechanism and the rotary drive mechanism 3032.

[0045] In summary, the platform movable gantry machine tool provided in this embodiment has the following advantages:

[0046] ① Automatic positioning: The direct drive module 303 drives the work surface 301 to reciprocate along the straight guide rail 302, which can automatically adjust the position of the workpiece, improve production efficiency, and reduce manual operations.

[0047] ② Expanding the working range: While keeping the actual area of ​​the work table 301 unchanged, the working range of the machine tool can be widened and the applicability of the machine tool can be improved by moving the work table 301.

[0048] ③ Precise positioning: The hydraulic clamping mechanism 304 and the positioning column 305 on the work table 301 can ensure the precise positioning of the workpiece, improve the processing accuracy, reduce the auxiliary time during the processing, and improve production efficiency.

[0049] ④ Structural stability: The reinforcement components of the straight guide rail 302, such as the transverse portion 3022 and the inclined portion 3023, improve the structural stability of the rectangular frame 3021 and ensure the processing accuracy and service life of the machine tool.

[0050] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
