Description

Technical Field

[0001] The present application relates to the technical field of laser cutting, and particularly to a moving device, a gantry and a processing device. Background Art

[0002] With the development of laser technology, laser cutting machines have been widely used in industries such as sheet metal, steel structure, precision machinery, medical treatment, and shipbuilding. In recent years, ultra-large-format laser cutting machines have developed rapidly. Ultra-large-format laser cutting machines can complete the cutting of super-large workpieces at one time, and have fast cutting speed and high cutting accuracy, and are gradually replacing plasma cutting machines and flame cutting machines.

[0003] Ultra-large-format laser cutting machines have a bed body with a large size. Due to the high processing difficulty of an integral bed body, a split bed body is generally used at present. The split bed body needs to be processed in sections and then spliced. However, the processing accuracy (such as parallelism, flatness, etc.) of the spliced split bed body will be lower than that of the integral bed body.

[0004] After the rack and the gear are engaged, by driving the gear to rotate, the cross beam can move on the split bed body. However, due to the processing error and assembly error of the split bed body, during the movement of the cross beam on the split bed body, there are problems of too tight or too loose meshing between the gear and the rack. If the rack and the gear are meshed too tightly, the rack, the gear and the bearing are easily worn, and the movement accuracy of the cross beam will be affected. If the rack and the gear are meshed too loosely, the movement accuracy of the cross beam will be affected, and then the processing accuracy of the workpiece will be directly affected.

[0005] In the related art, although elastic members such as springs are used to keep the gear and the rack engaged, there are still problems of too tight or too loose meshing between the gear and the rack, and the movement accuracy of the cross beam is still insufficient. Utility Model Content

[0058] Refer to Figure 1 and Figure 2 (appropriately refer to Figure 4 ), for the mobile device according to the first aspect embodiment of the present application, assuming that the included angle between the first direction and the second direction is greater than zero (refer to Figure 2 , for example, the first direction is the front-back direction, and for example, the second direction is the left-right direction), the mobile device includes a support frame 100, a gear 210, a rack 220, a first connecting member 310, a second connecting member 320, a driving assembly 400, and a pre-tightening assembly 500. The first connecting member 310 is slidably connected to the support frame 100, and the sliding direction of the first connecting member 310 relative to the support frame 100 is the first direction. The second connecting member 320 is slidably connected to the first connecting member 310, and the sliding direction of the second connecting member 320 relative to the first connecting member 310 is the second direction.

[0059] The rack 220 is installed on the support frame 100, and the length direction of the rack 220 is arranged along the first direction. The gear 210 meshes with the rack 220. The driving assembly 400 is installed on the second connecting member 320, and the driving assembly 400 is used to drive the gear 210 to rotate. The pre-tightening assembly 500 includes an elastic member 520 and an adjusting member 510.

[0060] The mobile device according to the embodiment of the present application has at least the following beneficial effects: By changing the deformation amount of the elastic member 520 through the adjusting member 510, the elastic force exerted by the elastic member 520 on the gear 210 and the rack 220 can be changed. After the meshing tightness of the gear 210 and the rack 220 is adjusted to the target range, the problems of too loose or too tight meshing between the gear 210 and the rack 220 can be effectively improved, which is beneficial to improving the motion accuracy of the mobile device.

[0061] Refer to Figure 1 and Figure 2 In some embodiments of the present application, the elastic member 520 includes a compression spring 521, the adjusting member 510 includes a bolt 511, the first connecting member 310 is provided with a threaded hole 311, and the second connecting member 320 is provided with a through hole 321.

[0062] After the compression spring 521 is compressed, the bolt 511 can apply a force to the first connecting member 310 and directly apply a force to the second connecting member 320, so that the first connecting member 310 and the second connecting member 320 move relative to each other, and then the gear 210 and the rack 220 approach each other. By rotating the bolt 511, the compression amount of the compression spring 521 can be changed, and then the meshing tightness when the gear 210 and the rack 220 mesh can be changed.

[0063] In other embodiments, the elastic member 520 may also include one of a rubber tube, a disc spring, and a bellows. The installation methods of the rubber tube, the disc spring, and the bellows are the same as those of the compression spring 521, and will not be repeated here.

[0064] Refer to Figure 2 In the improved solution of the above embodiment, at least two pre-tightening assemblies 500 are provided, and the pre-tightening assemblies 500 are arranged at intervals.

[0065] After multiple pre-tightening components 500 are provided, the multiple pre-tightening components 500 can apply forces to multiple positions of the first connecting member 310 and the second connecting member 320, and the first connecting member 310 and the second connecting member 320 will be more evenly stressed, and the gear 210 and the rack 220 will be more stable when meshing.

[0066] Specifically, the number of the pre-tightening components 500 can be two, three, four or other numbers.

[0067] Refer to Figure 1 , in some embodiments of the present application, the mobile device further includes a first sliding assembly 230, and the first sliding assembly 230 includes a first sliding rail 231 and a first sliding block 232. The first sliding block 232 is installed on the first connecting member 310. The first sliding rail 231 is installed on the second connecting member 320, the first sliding rail 231 is slidably connected to the first sliding block 232, and the length direction of the first sliding rail 231 is arranged along the second direction.

[0068] Through the sliding cooperation of the first sliding rail 231 and the first sliding block 232, the second connecting member 320 can slide relative to the first connecting member 310 along the second direction, and the sliding friction between the second connecting member 320 and the first connecting member 310 is smaller.

[0069] Refer to Figure 1 , in an improved solution of the above embodiment, at least two first sliding assemblies 230 are provided, and the first sliding assemblies 230 are spaced apart from each other.

[0070] By providing multiple first sliding assemblies 230, the bearing capacity of the second connecting member 320 is stronger, and the load of each first sliding assembly 230 is smaller, and the service life of the first sliding assembly 230 is longer.

[0071] Specifically, the number of the first sliding assemblies 230 can be two, three, four or other numbers.

[0072] Refer to Figure 1 , in some embodiments of the present application, the mobile device further includes a second sliding assembly 240, and the second sliding assembly 240 includes a second sliding block 241 and a second sliding rail 242. The second sliding block 241 is installed on the first connecting member 310. The second sliding rail 242 is installed on the support frame 100, the second sliding rail 242 is slidably connected to the second sliding block 241, and the length direction of the second sliding rail 242 is arranged along the first direction.

[0073] Through the sliding cooperation of the second sliding block 241 and the second sliding rail 242, the first connecting member 310 can slide relative to the support frame 100 along the first direction, and the sliding friction between the first connecting member 310 and the support frame 100 is smaller.

[0074] Refer to Figure 3, in some embodiments of the present application, the driving assembly 400 includes a motor 410 and a speed reducer 420.

The input shaft 421 is in transmission connection with the rotating shaft 411, and the output shaft 422 is in transmission connection with the gear 210.

[0075] Thus, when the motor 410 is powered on and operates, the gear 210 can be driven at an appropriate speed and torque.

[0076] Specifically, the input shaft 421 and the rotating shaft 411 are usually connected by a coupling, and the output shaft 422 and the gear 210 are usually connected by a key and a set screw.

[0077] In other embodiments, the driving assembly 400 may also include a rotary cylinder to drive the gear 210 to rotate.

[0078] Refer to Figure 2 , in some embodiments of the present application, the first direction and the second direction are perpendicular.

[0079] The first direction and the second direction are perpendicular, that is, the moving direction of the second connecting member 320 relative to the first connecting member 310 is perpendicular to the sliding direction of the first connecting member 310 relative to the support frame 100. Since the gear 210 is installed on the second connecting member 320 and the rack 220 is installed on the support frame 100, the force applied by the preloading assembly 500 to the gear 210 is perpendicular to the length direction of the rack 220. The force applied by the preloading assembly 500 is mainly used to make the gear 210 mesh with the rack 220. The component force of the force applied by the preloading assembly 500 in other directions is smaller, and the efficiency of the force applied by the preloading assembly 500 is higher.

[0080] In other embodiments, the included angle between the first direction and the second direction can be 89°, 85° or other angles.

[0081] Refer to Figure 4 and Figure 5 , according to the gantry of the second aspect embodiment of the present application, it includes a moving device and a cross beam 600.
