Description
Technical Field
[0001] This utility model relates to the technical field of all-position automatic welding devices, specifically a dual-drive structure in an all-position automatic welding device. Background Technology
[0002] Traditional all-position automatic welding devices suffer from unstable drive structures, failing to guarantee continuous and stable operation of the open gear. Referring to Chinese Patent No. CN108747191, a dual-drive structure for an all-position automatic welding device is disclosed. This structure can drive the open gear to continuous and stable operation and enables rapid installation of all components.
[0003] However, the dual-drive mechanism has a large number of gears. During installation, it is necessary to ensure that the corresponding two gears are in a meshing state. Therefore, it is necessary to adjust each gear multiple times, which makes the installation difficult. At the same time, each dimension is directly installed in the housing. Due to the small space inside the housing, the operation of adjusting the gears to a meshing state is further increased. Utility Model Content
[0004] The purpose of this invention is to provide a dual-drive structure in an all-position automatic welding device, which effectively solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution.
[0006] A dual-drive structure in an all-position automatic welding device includes a housing and a gear drive module. The gear drive module includes a mounting base, a drive rack, a transmission belt, and a pair of transmission racks. The drive rack and the two transmission racks are mounted on the mounting base. The two transmission racks are located below the drive rack and are arranged symmetrically. The transmission belt is meshed and fitted onto the drive rack and the two transmission racks. The mounting base is detachably installed inside the housing.
[0007] Therefore, the provided dual-drive structure allows for the pre-assembly of the mounting base, drive rack, transmission rack, and transmission belt outside the housing, followed by the overall installation of the gear drive module inside the housing. This is more convenient and faster than installing the gears inside the housing, and it also reduces the installation difficulty. Furthermore, the present invention uses fewer gears, thus requiring fewer adjustments to the gear meshing, further reducing the installation difficulty.
[0008] Furthermore, the housing has a cylindrical part with a circular hole, and the housing has an annular groove distributed around the cylindrical part with a circular hole. The bottom of the housing has a notch, and the open gear is rotatably installed in the annular groove. When the gear drive module is fully installed, both transmission racks mesh with the open gear.
[0009] Furthermore, the distance between the two transmission racks is greater than the span of the break in the open gear.
[0010] Furthermore, a pair of limiting rings are fixedly fitted on both the drive rack and the two transmission racks, and the transmission belt is respectively limited between the two limiting rings.
[0011] Furthermore, the housing has three insertion holes evenly distributed inside, and the mounting base has three insertion rods evenly distributed on the back. When the gear drive module is fully installed, each insertion rod is matched and inserted into the corresponding insertion hole.
[0012] Furthermore, the mounting base is provided with mounting hole B, and the rack shaft A of the drive rack is fitted into the mounting hole B.
[0013] Furthermore, the housing is provided with a through hole, and when the gear drive module is fully installed, the rack shaft A extends to the outside of the housing by passing through the mounting hole B and the through hole in sequence.
[0014] Furthermore, the mounting base is provided with a pair of mounting holes A, and the rack shafts B of the two transmission racks are respectively matched and inserted into the mounting holes A.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.
[0016] The dual-drive structure provided by this utility model allows for the pre-assembly of the mounting base, drive rack, transmission rack, and transmission belt outside the housing, followed by the overall installation of the gear drive module inside the housing. This is more convenient and faster than installing the gears inside the housing, and reduces the installation difficulty. Furthermore, the utility model uses fewer gears, thus requiring fewer adjustments to the gear meshing, further reducing the installation difficulty.
[0017] This invention fixes a pair of limiting rings on both the drive rack and the transmission rack, thus limiting the transmission belt between the two limiting rings on the drive rack and the transmission rack. This can prevent the transmission belt from slipping off the drive rack and the transmission rack, effectively ensuring the stability of the operation. Attached Figure Description

[0027] Please see Figures 1-5This utility model provides a dual-drive structure in an all-position automatic welding device, including a housing 1 and a gear drive module 3. The gear drive module 3 includes a mounting base 31, a drive rack 32, a transmission belt 34, and a pair of transmission racks 33. The drive rack 32 and the two transmission racks 33 are mounted on the mounting base 31. The two transmission racks 33 are located below the drive rack 32 and are symmetrically arranged. The transmission belt 34 is meshed and fitted onto the drive rack 32 and the two transmission racks 33. The mounting base 31 is detachably installed inside the housing 1. The drive rack 32 and the two transmission racks 33 are respectively mounted on the mounting base 31, and then the transmission belt 34 is fitted onto the drive rack 32 and the two transmission racks 33 to achieve the pre-assembly of the gear drive module 3. Then, the mounting base 31 is installed into the housing 1 to achieve the assembly of the gear drive module 3 with the housing 1.
[0028] The dual-drive structure provided by this utility model allows for the pre-assembly of the mounting base 31, drive rack 32, transmission rack 33, and transmission belt 34 outside the housing 1, followed by the overall installation of the gear drive module 3 inside the housing 1. This is more convenient and faster than installing the gears inside the housing 1, and reduces the installation difficulty. Furthermore, the utility model uses fewer gears, thus requiring fewer adjustments to the gear meshing, further reducing the installation difficulty.
[0029] Specifically, the housing 1 has a cylindrical part 11 with a circular hole, and the housing 1 has an annular groove 12 distributed around the cylindrical part 11. The bottom of the housing 1 is provided with a notch 13. The open gear 2 is rotatably installed in the annular groove 12. When the gear drive module 3 is fully installed, the two transmission racks 33 are meshed with the open gear 2. After the gear drive module 3 is pre-installed into the housing 1, the open gear 2 is installed into the annular groove 12 to realize the overall assembly of the structure.
[0030] Specifically, the distance between the two transmission racks 33 is greater than the span of the break on the open gear 2, ensuring that after one transmission rack 33 is separated from the open gear 2, the other transmission rack 33 remains engaged with the open gear 2, thereby ensuring that the open gear 2 can continue to operate.
[0031] Specifically, a pair of limiting rings 35 are fixedly fitted on both the drive rack 32 and the two transmission racks 33. The transmission belt 34 is respectively limited between the two limiting rings 35. By fixing a pair of limiting rings 35 on both the drive rack 32 and the transmission rack 33, the transmission belt 34 is limited between the two limiting rings 35 on the drive rack 32 and the transmission rack 33. This can block and prevent the transmission belt 34 from falling off the drive rack 32 and the transmission rack 33, effectively ensuring the stability of the operation process.
[0032] Specifically, the housing 1 has three insertion holes 14 evenly distributed inside, and the mounting base 31 has three insertion rods 313 evenly distributed on the back. When the gear drive module 3 is installed in place, each insertion rod 313 is matched and inserted into the corresponding insertion hole 14. The insertion rods 313 are inserted into each insertion hole 14 one by one to realize the installation of the mounting base 31.
[0033] Specifically, the mounting base 31 is provided with a mounting hole B312, and the rack shaft A321 of the drive rack 32 is matched and inserted into the mounting hole B312. The rack shaft A321 is inserted into the mounting hole B312 to realize the assembly between the mounting base 31 and the drive rack 32.
[0034] Specifically, the housing 1 is provided with a through hole 15. When the gear drive module 3 is installed in place, the rack shaft A321 extends to the outside of the housing 1 through the mounting hole B312 and the through hole 15 in sequence. By providing the through hole 15, the rack shaft A321 can be guided to the outside of the housing 1, which is convenient for connecting with the output shaft of the drive motor as a drive source.
[0035] Specifically, the mounting base 31 is provided with a pair of mounting holes A311, and the rack shafts B331 of the two transmission racks 33 are respectively matched and inserted into the mounting holes A311. The rack shafts B331 are inserted into the mounting holes A311 one by one to realize the assembly between the mounting base 31 and the transmission racks 33.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
