[0033] As Figures 1-8As shown, the embodiment of the present application discloses a gantry module structure for machining, which comprises a first frame body 1, a module mechanism 4, a lifting mechanism 5, a connecting assembly 8 and an adjusting assembly 11. The first frame body 1 is provided with two parallel structures, the two first frame bodies 1 are fixed through a connecting beam 2, and the mutually close sidewalls of the two first frame bodies 1 are both provided with mounting grooves.

[0034] The module mechanism 4 is arranged between the two sliding seats 3, and comprises a second frame body 41, a moving frame 42, a rotating rod 43, a gear 44, a rack 45 and a driving motor 46. The second frame body 41 is arranged between the two sliding seats 3. A limiting through hole 7 is arranged through the sidewall of the second frame body 41, and the length direction of the limiting through hole 7 is parallel to the length direction of the second frame body 41. The moving frame 42 is slidably sleeved on the second frame body 41, and the rotating rod 43 is rotatably installed on the moving frame 42 and movably passes through the limiting through hole 7. The gear 44 is fixedly sleeved on the rotating rod 43 and located in the second frame body 41, the rack 45 is fixed in the second frame body 41 and engaged with the gear 44, and the driving motor 46 is fixed on the moving frame 42 and drives the rotating rod 43 to rotate.

[0035] The lifting mechanism 5 is arranged on the two first frame bodies 1, and comprises lifting assemblies 51 and rotating assemblies 52. The lifting assemblies 51 are provided in two groups and symmetrically arranged about the second frame body 41.

[0036] Each lifting assembly 51 comprises a lifting unit 511 and a fixing unit 512. The lifting unit 511 comprises a slave synchronous wheel 5111, a master synchronous wheel 5112, a synchronous belt 5113 and a U-shaped plate 5114. The slave synchronous wheel 5111 and the master driven wheel are rotatably arranged in the mounting groove, the synchronous belt 5113 is arranged in the mounting groove and engaged with the slave synchronous wheel 5111 and the master synchronous wheel 5112. The U-shaped plate 5114 is in clamping fit with the inner side of the synchronous belt 5113, and one side of the U-shaped plate 5114 is provided with a wave-shaped clamping groove in clamping fit with the inner side of the synchronous belt 5113. The sidewall of the sliding seat 3 close to one side of the U-shaped plate 5114 is provided with a positioning hole 6, and the sliding seat 3 and the U-shaped plate 5114 are respectively located on both sides of the synchronous belt 5113.

[0037] The fixing unit 512 is used for fixing the U-shaped plate 5114 and the sliding seat 3 to clamp the synchronous belt 5113. The fixing unit 512 comprises a threaded rod 5121 and a limiting block 5122. The threaded rod 5121 is arranged on the sidewall of the U-shaped plate 5114 away from the sliding seat 3 and in gap fit with the U-shaped plate 5114. The threaded rod 5121 is in threaded connection with the positioning hole 6, and the limiting block 5122 is fixed to the end of the threaded rod 5121 away from the sliding seat 3.

[0038] The worker first slides the slide 3 into the installation groove during the gantry module assembly process, then rotates the slave synchronous wheel 5111 and the main synchronous wheel 5112 into the installation groove, and then connects the synchronous belt 5113 with the slave synchronous wheel 5111 and the main synchronous wheel 5112, and then connects the U-shaped plate 5114 with the inner side of the synchronous belt 5113, and finally connects the threaded rod 5121 with the positioning hole 6, so that the U-shaped plate 5114 is fixed with the slide 3 to clamp the synchronous belt 5113. Since the module mechanism 4 is arranged between the slides 3, the overall assembly of the gantry module can be completed, the cumbersome operation of the prior art is avoided, and the efficiency of the overall assembly of the gantry module is improved. When the gantry module is used, the motor 523 is rotated to drive the driving rod 522 to rotate, so that the two main synchronous wheels 5112 fixed with the driving rod 522 and the synchronous belt 5113 engaged with the slave synchronous wheel 5111 and the main synchronous wheel 5112 are all rotated. Since the U-shaped plate 5114 and the slide 3 clamp the synchronous belt 5113, the purpose of moving the module mechanism 4 is achieved.

[0039] The connecting assembly 8 is provided with two groups and is arranged on the two first frame bodies 1 respectively, and the connecting assembly 8 is used to connect the slide 3 and the second frame body 41. Each group of connecting assemblies 8 includes a mounting plate 81, a fixed plate 82, a threaded column 83 and a rectangular block 84, and the mounting plate 81 is fixed on the side wall of the slide 3 near the second frame body 41. The fixed plate 82 is fixed on the side wall of the second frame body 41 near the slide 3 and is in close contact with the mounting plate 81, and a rectangular through hole 9 is provided on the side wall of the fixed plate 82 away from the mounting plate 81, through which the rectangular block 84 passes. The threaded column 83 is arranged on the side wall of the mounting plate 81 near the fixed plate 82 and is threadedly connected, the threaded column 83 passes through the rectangular through hole 9, and the rectangular block 84 is fixed on one end of the threaded column 83 near the fixed plate 82 and is in close contact with the side wall of the fixed plate 82 away from the mounting plate 81. The worker rotates the rectangular block 84 to drive the threaded column 83 to rotate, because the threaded column 83 is arranged on the side wall of the mounting plate 81 near the fixed plate 82, so that the threaded rod 5121 drives the rectangular block 84 to move away until the orthogonal projection of the rectangular block 84 coincides with the orthogonal projection of the rectangular through hole 9. At this time, the second frame body 41 is pushed away from the mounting plate 81, in this process, the fixed plate 82 moves away from the mounting plate 81, and the rectangular block 84 passes through the rectangular through hole 9, so that the disassembly operation of the second frame body 41 and the slide 3 can be realized, which is convenient for the disassembly and maintenance of the second frame body 41 in the later period.

[0040] The adjusting assembly 11 is provided with two groups and is arranged on the two first frame bodies 1 respectively. The adjusting assembly 11 adjusts the distance between the slave sprocket 5111 and the master sprocket 5112. Each group of the adjusting assembly 11 comprises a sliding block 111, an adjusting screw 112 and an adjusting motor 113. The sliding block 111 is slidingly installed in the adjusting through hole 10. The end of the driven rod 521 away from the second frame body 41 is rotationally connected with the side wall of the side of the sliding block 111 close to the second frame body 41. The adjusting screw 112 is rotationally installed in the adjusting through hole 10 and is threadedly connected with the sliding block 111. The adjusting motor 113 is fixed on the first frame body 1 and drives the adjusting screw 112 to rotate. The two adjusting motors 113 are electrically connected through a microcontroller (the model of the microcontroller is NXP LPC1500. The microcontroller can control two motors at the same time. The line connection of the microcontroller and the motor and the working principle and structure of the microcontroller are prior arts and do not need to be introduced too much). When the adjusting motor 113 works, the adjusting screw 112 is driven to rotate. Since the sliding block 111 is slidingly matched with the adjusting through hole 10 and the adjusting screw 112 is threadedly connected with the sliding block 111, the sliding block 111, the driven rod 521 connected with the sliding block 111 and the slave sprocket 5111 fixed with the driven rod 521 all move upward or downward, so as to change the distance between the slave sprocket 5111 and the master sprocket 5112. On the one hand, the distance between the slave sprocket 5111 and the master sprocket 5112 is reduced, which facilitates the work of disassembling or assembling the synchronous belt 5113 from the slave sprocket 5111 and the master sprocket 5112. On the other hand, when the synchronous belt 5113 is loosened due to elastic deformation after long-time work, the normal work of the synchronous belt 5113 can be ensured by increasing the distance between the slave sprocket 5111 and the master sprocket 5112, so as to prolong the service life of the synchronous belt 5113.

[0041] The distance between the second frame body 41 and the two first frame bodies 1 is greater than 10 cm. This facilitates the rotation of the rectangular block 84 between the second frame body 41 and the first frame body 1 by the worker.

[0042] The limiting column 12 is fixed on the side wall of the side of the U-shaped plate 5114 close to the sliding seat 3. The limiting slot 13 is formed in the side wall of the side of the sliding seat 3 close to the U-shaped plate 5114. In the process of fixing the U-shaped plate 5114 and the sliding seat 3, the limiting column 12 is inserted into the limiting slot 13, so that the threaded rod 5121 is aligned with the positioning hole 6, thereby facilitating the connection between the U-shaped plate 5114 and the sliding seat 3 and improving the assembly efficiency of the whole gantry module.

[0043] The distance between the second frame body and the two first frame bodies is greater than 10 cm. This facilitates the rotation of the rectangular block between the second frame body and the first frame body by the worker.

[0044] The side wall near the one side of the U-shaped plate is fixed with a limiting column, and the side wall near the one side of the sliding base is provided with a limiting slot matched with the limiting column.

[0045] The use principle of the gantry module structure for machining in the embodiment is as follows.

[0046] The preferred embodiments of the utility model are described above, and the protection scope of the utility model is not limited to the above-mentioned embodiments only, and any technical scheme belonging to the idea of the utility model belongs to the protection scope of the utility model. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model can also be considered as the protection scope of the utility model.
