Description

Technical Field

[0001] This invention relates to the field of water pump impeller welding, and more specifically to a welding auxiliary device for processing water pump impellers. Background Technology

[0002] As a core general-purpose machine in the field of fluid transportation, water pumps are widely used in many key areas of the national economy, such as water conservancy projects, municipal water supply, industrial circulation, agricultural irrigation and petrochemicals. As the core component of water pumps to realize energy conversion, the impeller's structural design, processing precision and welding quality directly determine the hydraulic performance, operational stability and service life of the water pump.

[0003] Currently, the clamping equipment used in the welding of water pump impellers is mostly designed based on traditional single-machine processing needs. When adapting to mass production, it reveals many shortcomings. First, the batch clamping efficiency is low and the positioning consistency is poor. Most small and medium-sized production enterprises still rely on manual clamps to complete the impeller clamping, which is cumbersome and inefficient. Second, the existing welding platform needs to be rotated to a certain position before it can be raised to the corresponding height. It is not convenient to automatically raise to the initial position height when switching to the next position, resulting in poor applicability and failure to meet actual usage requirements.

[0004] Therefore, there is a need to provide a welding auxiliary device for the machining of water pump impellers, which aims to solve the above problems. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] See Figures 1 to 8 A welding auxiliary device for processing water pump impellers includes a base plate 1, on which a first support 2, a worktable 3, and a welding robot 4 are mounted. The worktable 3 is movably mounted on the first support 2, and the welding robot 4 is mounted on one side of the worktable 3. The worktable 3 has several equally spaced placement slots 5 for placing water pump impellers. The device also includes: A batch positioning and clamping mechanism is installed inside the workbench 3 for batch positioning and clamping of water pump impellers. The batch positioning and clamping mechanism includes a fixed ring 6, a rotating ring 7 and a deflecting plate 8 for clamping the water pump impellers. The fixed ring 6 is fixedly installed inside the workbench 3 by the second support seat 16. The deflecting plate 8 is limited and clamped by the rotation of the rotating ring 7. One end of the deflecting plate 8 is provided with a clamping block 9 for clamping the water pump impellers.

[0031] Furthermore, the batch positioning clamping mechanism also includes a connecting ring 17 for driving the actuating plate 8 to rotate. The rotating ring 7 is fixedly connected to the connecting ring 17 via the traction plate 14. The fixed ring 6 has a second slide groove 13 for adapting to the sliding connection of the traction plate 14. The actuating plate 8 is rotatably connected to the rotating ring 7 via the first connecting shaft 10. The other end of the actuating plate 8 is provided with a second connecting shaft 11. The fixed ring 6 has a first slide groove 12 adapted to slide and connect with the second connecting shaft 11.

[0032] Furthermore, the batch positioning clamping mechanism also includes a worm 21 and a worm wheel 20 for driving the connecting ring 17 to rotate. The connecting ring 17 is fixedly connected to a stepped collar 19 via a fixed post 18. The stepped collar 19 is rotatably mounted on the outside of the second support base 16. The worm wheel 20 is fixedly connected to the stepped collar 19. The worm 21 is meshed with the worm wheel 20. The worm 21 is rotatably mounted inside the worktable 3.

[0033] Furthermore, the batch positioning and clamping mechanism also includes a first motor 27 for driving the worm gear 21 to rotate. The worm gear 21 is rotatably connected to a third connecting shaft 23 via a synchronous belt 22. The third connecting shaft 23 is rotatably mounted on a second support base 16. One end of the third connecting shaft 23 is fixedly connected to a driven bevel gear 24. A driving bevel gear 25 is meshed with the driven bevel gear 24. The driving bevel gear 25 is rotatably connected to the inside of the worktable 3 via a fourth connecting shaft 26. The fourth connecting shaft 26 is fixedly connected to the output shaft of the first motor 27. The first motor 27 is fixedly mounted inside the worktable 3.

[0034] Preferably, when welding the water pump impellers, multiple water pump impellers can be placed in the placement slot 5 on the workbench 3. After all impellers are placed, the first motor 27 drives the driving bevel gear 25 on the fourth connecting shaft 26 to rotate. Under the meshing connection between the driving bevel gear 25 and the driven bevel gear 24, the third connecting shaft 23 is driven to rotate. Under the synchronous drive of the synchronous belt 22, the worm gear 21 is driven to rotate. Under the meshing connection between the worm gear 21 and the worm wheel 20, the stepped collar 19 is driven to rotate at the second support. On the outside of seat 16, the corresponding synchronous drive connecting ring 17 drives the rotating ring 7 on the traction plate 14 to rotate, so that the clamping blocks 9 on the actuating plate 8 move closer to each other, thereby completing the synchronous clamping operation of multiple sets of water pump impellers, which is convenient for batch positioning and clamping. After all the water pump impellers are welded by the welding robot 4, the first motor 27 drives in reverse, which can drive the clamping blocks 9 on multiple sets of actuating plates 8 away from the limit on the water pump impellers, thereby facilitating the synchronous removal of multiple sets of water pump impellers and subsequent installation.

[0035] This batch synchronous clamping and unloading method revolutionizes traditional clamping operations, significantly shortens the batch processing cycle, matches the overall processing rhythm of the production line with the operating efficiency of the welding equipment, ensures the consistency of batch processing, and correspondingly reduces reliance on manual labor and labor intensity, thereby optimizing labor costs and significantly improving the efficiency of subsequent welding processes.

[0036] like Figures 1 to 11 As shown, this embodiment, based on the above embodiment, also includes an auxiliary lifting mechanism, which is installed at the connection between the first support base 2 and the worktable 3, and is used to drive the worktable 3 to adjust the rotation height. The auxiliary lifting mechanism includes a square shaft 31 and a lead screw 37 for height control. The square shaft 31 is threaded to the lead screw 37. The square shaft 31 is fixedly connected to a docking post 29 through a limiting plate 30. The bottom of the worktable 3 is provided with a fixed collar 28 that is adapted to rotate and connect with the docking post 29.

[0037] Furthermore, the auxiliary lifting mechanism also includes a square sleeve 32 for guiding the square shaft 31 to move. The square shaft 31 is slidably inserted through the square sleeve 32. The square sleeve 32 is fixedly installed on the third support base 36 by an L-shaped fixing plate 35. The lead screw 37 is fixedly connected to the output shaft of the third motor 15. The third motor 15 is fixedly installed inside the third support base 36.

[0038] Furthermore, the auxiliary lifting mechanism also includes a guide rod 33 and a guide cylinder 34 for auxiliary guiding lifting. One end of the guide rod 33 is fixedly connected to the worktable 3, and the guide rod 33 is slidably connected to the inside of the guide cylinder 34. The guide cylinder 34 is fixedly installed on the first gear 38, and the first gear 38 is rotatably connected to the third support base 36.

[0039] Furthermore, the auxiliary lifting mechanism also includes a sixth connecting shaft 42 for driving the first gear 38 to rotate. The first gear 38 is meshed with a second gear 39 on one side. The second gear 39 is rotatably connected to the inside of the worktable 3 via a fifth connecting shaft 40. The fifth connecting shaft 40 is rotatably connected to the sixth connecting shaft 42 via a bevel gear pair 41. The sixth connecting shaft 42 is rotatably mounted on the third support base 36, and the sixth connecting shaft 42 is fixedly connected to the output shaft of the second motor 43. The second motor 43 is fixedly mounted inside the third support base 36.

[0040] Preferably, in this embodiment, when the pump impeller station is rotated and switched, the output shaft of the second motor 43 drives the sixth connecting shaft 42 to rotate, and under the connection relationship of the bevel gear pair 41, it drives the second gear 39 on the fifth connecting shaft 40 to rotate. Thus, under the meshing connection relationship between the second gear 39 and the first gear 38, it drives the worktable 3 connected to it to rotate and switch the station.

[0041] As the welding robot 4 performs welding according to the predetermined initial program, the water pump impeller on the workbench 3 must be moved to the initial height processing position in advance. At this time, while the second motor 43 drives the workbench 3 to rotate and switch positions, the third motor 15 can perform adjustment operations simultaneously. That is, the third motor 15 drives the lead screw 37 to rotate. Thus, at the point where the square sleeve 32 is threadedly connected to the lead screw 37, the square shaft 31 is limited and slidably connected to the square sleeve 32, and the guide rod 33 on the workbench 3 is limited and slidably connected to the guide cylinder 34, the height adjustment is realized at the same time as the rotation and switching of positions, so that the water pump impeller of the next position moves to the initial height processing position, thereby further improving the welding processing efficiency of the water pump impeller.

[0042] By ensuring the adjustment of the initial station height while switching between workstations, redundant time during workstation switching is eliminated, enabling seamless connection of the processing flow. This significantly shortens the waiting time between processes, greatly enhances the continuity of batch processing, adapts to automated loading and unloading requirements, reduces manual intervention costs, improves multi-process compatibility, enhances the flexible production level of equipment, and significantly improves welding efficiency.

[0043] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
