[0033] Next, refer to Figures 1 to 4 to describe the gantry machine tool of the present application in detail.

[0034] Refer to Figure 1 and Figure 2, The gantry machine tool according to an embodiment of the present invention includes a base 100, a gantry 200, a processing platform 300, and a processing module 400.

[0035] Two heightening blocks 110 are provided on the base 100 and are distributed along a first horizontal direction; the gantry 200 includes a cross beam 210 and two columns 220 respectively provided at opposite ends of the cross beam 210, and the two columns 220 are respectively slidably provided on the two heightening blocks 110 along a second horizontal direction; the processing platform 300 is slidably provided on the base 100 along the second horizontal direction and is located between the two heightening blocks 110, and the processing platform 300 is used for carrying workpieces to be processed; the processing module 400 is slidably provided on the cross beam 210 along the first horizontal direction and is located above the processing platform 300, and the processing module 400 is used for processing the workpieces to be processed on the processing platform 300.

[0036] It should be noted that when the gantry machine tool of the present invention is working, the processing platform 300 can slide relative to the base 100 along the second horizontal direction to reciprocate between the loading position and the processing position. After the processing platform 300 slides along the second horizontal direction to the loading position, the staff can load the workpiece to be processed onto the processing platform 300. Then, the processing platform 300 can slide along the second horizontal direction to the processing position. At this time, the processing platform 300 can be located directly below the gantry 200; since the columns 220 of the gantry 200 are slidably provided on the two heightening blocks 110 along the second horizontal direction, the gantry 200 can drive the processing module 400 to move along the second horizontal direction to adjust the relative position between the processing module 400 and the processing platform 300 in the second horizontal direction. Since the processing module 400 is slidably provided on the cross beam 210 along the first horizontal direction, the processing module 400 can slide relative to the cross beam 210 along the first horizontal direction to adjust the relative position between the processing module 400 and the processing platform 300 in the first horizontal direction, so that the processing module 400 can successfully complete the processing of each workpiece to be processed on the processing platform 300.

[0037] It can be understood that since two heightening blocks 110 are provided on the base 100 and are distributed along the first horizontal direction, and the two columns 220 of the gantry 200 are respectively slidably provided on the two heightening blocks 110 along the second horizontal direction, on the premise of ensuring a certain height of the processing module 400 on the gantry 200, the setting of the heightening blocks 110 enables the height of the columns 220 of the gantry 200 to be set smaller, so that the gantry 200 can slide more smoothly relative to the base 100 along the second horizontal direction.

[0038] It can be understood that since the processing platform 300 is slidably disposed on the base 100 along the second horizontal direction, and the gantry 200 is slidably disposed on the heightening block 110 along the second horizontal direction, thus, the processing platform 300 can slide relative to the base 100 along the second horizontal direction to realize the reciprocating movement of the processing platform 300 between the loading position and the processing position, and the gantry 200 can drive the processing module 400 to move relative to the base 100 along the second horizontal direction to realize the position adjustment of the processing module 400 relative to the base 100 in the second horizontal direction. Through the above settings, the displacements of both the processing platform 300 and the gantry 200 in the second horizontal direction can be set to be smaller, so that the structure of the entire gantry machine tool in the second horizontal direction can be set to be smaller, thereby reducing the space occupied by the entire gantry machine tool in the second horizontal direction. Correspondingly, under the same occupied space, the relative displacement amount of the processing module 400 disposed on the gantry 200 and the workpiece to be processed placed on the processing platform 300 in the second horizontal direction is larger, enabling the gantry machine tool of the present application to process larger products.

[0039] In some embodiments of the present invention, referring to Figure 2 and Figure 3 , a first slide rail 111 extending along the second horizontal direction is provided on the heightening block 110, a first slider is slidably provided on the first slide rail 111, and the column 220 is connected to the first slider; a first driving structure 120 is further provided on the heightening block 110, the first driving structure 120 is connected to the column 220 and is used to drive the gantry 200 to slide along the first slide rail 111.

[0040] It can be understood that in the gantry machine tool of the present invention, under the drive of the first driving structure 120, the gantry 200 can drive the first slider to slide along the first slide rail 111; the setting of the first slide rail 111 enables the gantry 200 to accurately move along the second horizontal direction under the drive of the first driving structure 120, thereby improving the accuracy of the gantry 200 sliding along the second horizontal direction.

[0041] In order to enable the gantry 200 to slide precisely along the second horizontal direction, in a further embodiment of the present invention, referring to Figure 2 and Figure 3 , the first driving structure 120 includes a first driver 121, a first lead screw 122, and a first sleeve 123. The first lead screw 122 extends along the second horizontal direction and is located on the side of the first slide rail 111 close to the processing platform 300. The first sleeve 123 is threadedly sleeved on the first lead screw 122. The column 220 is respectively connected to the first sleeve 123 and the first slider, and the first driver 121 is connected to the first lead screw 122 and is used to drive the first lead screw 122 to rotate self - rotatably.

[0042] Furthermore, driven by the first driver 121, the first lead screw 122 can rotate, so that the first sleeve 123 can drive the gantry 200 to slide along the second horizontal direction.

[0043] It can be understood that the arrangement of the first lead screw 122 and the first sleeve 123 enables the gantry 200 to move along the second horizontal direction with higher precision.

[0044] It can be understood that since the first lead screw 122 is arranged on the side of the first slide rail 111 close to the processing platform 300, the first lead screw 122 can be located closer to the middle of the entire gantry machine tool, thereby protecting the first lead screw 122 and reducing the interference of external factors on the first lead screw 122.

[0045] In some embodiments of the present invention, refer to Figure 2 , two second slide rails 211 arranged in parallel are provided on the cross beam 210. The second slide rails 211 extend along the first horizontal direction. A second slider is slidably provided on each second slide rail 211, and both second sliders are connected to the processing module 400; a second driving structure 230 is further provided on the cross beam 210. The second driving structure 230 is arranged between the two second slide rails 211. The second driving structure 230 is connected to the processing module 400 and is used to drive the processing module 400 to move along the first horizontal direction.

[0046] Furthermore, driven by the second driving structure 230, the processing module 400 can slide along the second slide rail 211 in the first horizontal direction.

[0047] It can be understood that the arrangement of the second slide rail 211 enables the processing module 400 to accurately move along the first horizontal direction under the drive of the second driving structure 230.

[0048] It can be understood that by providing two second slide rails 211 arranged in parallel and the second driving structure 230 is arranged between the two second slide rails 211, the two second slide rails 211 can cooperate to protect the second driving structure 230 and reduce the interference of external factors on the second driving structure 230.

[0049] In a specific embodiment of the present invention, refer to Figure 2 , the two second slide rails 211 are distributed along the vertical direction.

[0050] In order to improve the accuracy of the displacement of the processing module 400 along the first horizontal direction. In a further embodiment of the present invention, refer to Figure 2, the second driving structure 230 includes a second driver 231, a second lead screw 232, and a second sleeve 233. The second lead screw 232 is arranged to extend along the second horizontal direction. The second sleeve 233 is threadedly sleeved on the second lead screw 232 and is connected to the cross beam 210. The second driver 231 is connected to the second lead screw 232 and is used to drive the second lead screw 232 to rotate self - axially.

[0051] Furthermore, driven by the second driver 231, the second lead screw 232 can rotate self - axially, so that the second sleeve 233 can drive the processing module 400 to slide along the first horizontal direction.

[0052] It can be understood that the arrangement of the second lead screw 232 and the second sleeve 233 enables the processing module 400 to move along the first horizontal direction with higher precision.

[0053] In some embodiments of the present utility model, referring to Figure 4 , the processing module 400 includes a mounting base 410, a third driving structure 420, and a processing structure 430. Two third slide rails 411 arranged side by side are provided on the mounting base 410. The third slide rails 411 are arranged to extend along the vertical direction. A third slider is slidably provided on each of the third slide rails 411. The processing structure 430 is provided on the third slider. A tool 530 for processing a workpiece to be processed is detachably installed at the lower end of the processing structure 430. The third driving structure 420 is arranged between the two third slide rails 411 and is connected to the processing structure 430. The third driving structure 420 is used to drive the processing structure 430 to perform a lifting motion.

[0054] It can be understood that by sliding the gantry 200 relative to the base 100 in the second horizontal direction, the relative position of the processing structure 430 and the workpiece to be processed on the processing platform 300 in the second horizontal direction can be adjusted; by sliding the processing module 400 relative to the cross beam 210 in the first horizontal direction, the relative position of the processing structure 430 and the workpiece to be processed on the processing platform 300 in the first horizontal direction can be adjusted; driven by the third driving structure 420, the processing structure 430 can perform a lifting motion along the third slide rail 411 to adjust the relative position of the processing structure 430 and the workpiece to be processed on the processing platform 300 in the vertical direction.

[0055] It can be understood that by providing the third slide rails 411 extending along the vertical direction, the processing structure 430 can accurately slide along the vertical direction to reduce the offset amount of the processing structure 430 in the horizontal direction during the lifting motion.

[0056] It can be understood that by providing two third slide rails 411 arranged side by side and disposing the third drive structure 420 between the two third slide rails 411, the two third slide rails 411 can cooperate to protect the third drive structure 420, so as to reduce the interference of external factors on the third drive structure 420.

[0057] In order to improve the accuracy of the displacement of the processing structure 430 in the vertical direction, in a further embodiment of the present invention, the third drive structure 420 includes a third driver, a third lead screw and a third sleeve. The third lead screw is arranged to extend in the vertical direction. The third sleeve is threadedly sleeved on the third lead screw. The third driver is connected to the third lead screw and is used to drive the third lead screw to rotate.

[0058] Furthermore, driven by the third driver, the third lead screw can rotate, so that the third sleeve can drive the processing structure 430 to slide in the vertical direction.

[0059] It can be understood that the arrangement of the third lead screw and the third sleeve enables the processing structure 430 to move in the vertical direction with higher accuracy.

[0060] In some embodiments of the present invention, referring to Figure 1 and Figure 4 , the gantry machine tool further includes a tool magazine 500. The tool magazine 500 is disposed on one side of the processing structure 430. The tool magazine 500 includes a mounting main body 510 and a mounting frame 520. The mounting frame 520 is rotatably disposed on the mounting main body 510. A plurality of tool seats 521 are circumferentially distributed on the mounting frame 520. At least one tool seat 521 is detachably mounted with a tool 530. A loading and unloading position 511 is provided at the lower end of the mounting main body 510. The mounting frame 520 can rotate so that the tool seats 521 pass through the loading and unloading position 511 in sequence.

[0061] It should be noted that in the gantry machine tool of the present invention, the mounting frame 520 can rotate so that an empty tool seat 521 moves to the loading and unloading position 511. At this time, the tool 530 on the processing structure 430 can be detached and placed on this empty tool seat 521. Then, the mounting frame 520 can continue to rotate so that another tool seat 521 carrying the tool 530 moves to the loading and unloading position 511 for installing the tool 530 on the processing structure 430.

[0062] It can be understood that by providing the tool magazine 500, during the working process of the gantry machine tool of the present invention, the staff can replace the tool 530 on the processing structure 430 according to actual needs.

[0063] In a further embodiment of the present invention, referring to Figure 4, the tool magazine 500 further includes a connecting bracket 540 and an elastic connecting member 550. The connecting bracket 540 is connected to the mounting seat 410. The mounting body 510 is rotatably provided on the connecting bracket 540. The opposite ends of the elastic connecting member 550 are respectively connected to the mounting seat 410 and the mounting body 510, and are used to provide an elastic force for keeping the lower end of the mounting body 510 close to the processing structure 430. And when the third driving structure 420 drives the processing structure 430 to move above the loading and unloading position 511, under the elastic force of the elastic connecting member 550, the mounting body 510 can rotate so that the loading and unloading position 511 moves directly below the processing structure 430.

[0064] It can be understood that when the tool 530 on the processing structure 430 needs to be replaced, the mounting bracket 520 can rotate to move an empty tool holder 521 to the loading and unloading position 511. Then, the third driving structure 420 can drive the processing structure 430 to move upward so that the processing structure 430 moves above the loading and unloading position 511. During this process, under the elastic force of the elastic connecting member 550, the lower end of the mounting body 510 can always remain close to the processing structure 430 so that the tool holder 521 located at the loading and unloading position 511 can be engaged with the tool 530 on the processing structure 430, thereby realizing the separation of the tool 530 and the processing structure 430. Then, the mounting bracket 520 can rotate to move a tool holder 521 carrying the tool 530 to the loading and unloading position 511. Then, the third driving structure 420 can drive the processing structure 430 to move downward. During this process, the processing structure 430 can be connected to the tool 530 in the loading and unloading position 511 and drive the tool 530 to disengage from the tool holder 521. Furthermore, through the above process, the switching of the tool 530 on the processing structure 430 can be completed.

The plurality of processing platforms 300 are spaced apart along the first horizontal direction, and the plurality of processing modules 400 are spaced apart along the first horizontal direction.

[0066] It can be understood that by providing a plurality of processing platforms 300 and a plurality of processing modules 400 arranged in one-to-one correspondence, the gantry machine tool of the present invention can process a plurality of workpieces to be processed simultaneously, improving the working efficiency of the gantry machine tool of the present invention.
