Description

Technical Field

[0001] The present invention relates to the technical field of water pump processing, and more specifically, the present invention relates to an impeller welding device for water pump processing. Background Art

[0002] The water pump impeller is the core component in a water pump. It plays a crucial role. Its main function is to convert mechanical energy into the kinetic energy or pressure energy of the fluid. During the operation of the water pump, the impeller generates a strong centrifugal force through its rotational motion. This force causes the fluid to be sucked in and then discharged. The design and structure of the impeller have a crucial impact on the performance and efficiency of the water pump because they are directly related to the water absorption capacity and drainage efficiency of the water pump. In the impeller welding device, through precise welding technology, the strength and sealing performance of the impeller can be ensured, thereby improving the overall performance and reliability of the water pump. The precision of this welding technology is achieved through advanced technology and strict quality control to ensure that each impeller assembly can meet the design requirements, thus ensuring the stable operation of the water pump under various working conditions.

[0003] According to the patent document: CN117066742A, an impeller welding device for water pump processing and a water pump processing method disclosed therein include a support mechanism and a rotation mechanism. The support mechanism includes a base, on which a turntable assembly is provided, and a first clamping assembly is fixedly connected to the turntable assembly; the rotation mechanism includes a rotation assembly, and a second clamping assembly is fixedly connected to one side of the rotation assembly. In this solution, a turntable is provided, and multiple groups of first clamping assemblies are arranged on the turntable, which can clamp and fix multiple groups of parts one to be welded. The turntable can drive the first clamping assembly to move. The first clamping assembly can drive the upper clamping block and the lower clamping block to rotate through the setting of a second motor, so as to adjust the angle of part one. By setting a first electric push rod, the upper clamping block and the lower clamping block can be driven to lift, so as to adjust the height of part one, thereby flexibly adjusting part one; by setting an electric slide table, the horizontal movement of the second clamping assembly can be driven, thereby driving part two to move. By setting a third motor, the second clamping assembly can be driven to rotate, so as to adjust the angle of part two.

[0004] When welding the impellers of some water pumps, it is necessary to rotate the impellers to the same angle for welding. However, traditional manual operations are difficult to ensure that multiple impeller components can be accurately aligned to the same angle, which not only affects the welding quality and efficiency, but also increases the operation complexity and manual errors. Although the comparative document CN117066742A proposes an impeller splicing and welding device for water pump processing, through innovative mechanical structure design, although it effectively solves the problem that the bending degrees of impellers are different, and thus the welding angles are also different, and the existing splicing and welding devices are not flexible enough when adjusting the welding angle, there are still some limitations in its actual application. For example, when it is necessary to rotate the impellers to the same angle for welding, since each mechanism for adjusting the angle is controlled separately, the overall adjustment process is cumbersome and time-consuming, and the impellers cannot be accurately adjusted to the unified preset precise angle, affecting the welding accuracy and efficiency. In order to improve the welding accuracy and efficiency. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 8 - 10As shown in the figure, the welding table 1 includes a chassis 11. On the left side of the top of the chassis 11, two inverted L-shaped connecting vertical plates 12 are fixedly connected. In the middle of the top of the inner sides of the two inverted L-shaped connecting vertical plates 12, a T-shaped motor connecting plate 13 is fixedly connected. On the left side of the T-shaped motor connecting plate 13, a motor 14 is fixedly connected. On the right side of the top of the inner sides of the two inverted L-shaped connecting vertical plates 12, a columnar rotating rod connecting disc 16 is fixedly connected. On the right side of the front inverted L-shaped connecting vertical plate 12, a welding robot connecting plate 111 is fixedly connected. On the rear side of the welding robot connecting plate 111, a welding robot placing plate 113 is fixedly connected. The left side of the welding robot placing plate 113 is fixedly connected to the right outer wall of the columnar rotating rod connecting disc 16. On the top of the welding robot placing plate 113, a welding robot 112 is fixedly connected. In the middle of the inner wall of the columnar rotating rod connecting disc 16, a columnar rotating rod 17 is fixedly connected. On the inner wall of the columnar rotating rod connecting disc 16 on the left side of the columnar rotating rod 17, a second columnar rotating rod 18 is rotatably connected. The top and bottom ends of the columnar rotating rod 17 and the second columnar rotating rod 18 extend to the top and bottom of the columnar rotating rod connecting disc 16. The output end of the motor 14 is fixedly connected to a transmission disc 15. A crawler 110 is sleeved on the outer wall of the transmission disc 15. On the side of the crawler 110 away from the transmission disc 15, a second transmission disc 19 is sleeved. The inner wall of the second transmission disc 19 is fixedly connected to the outer wall of the top of the second columnar rotating rod 18. The bottom end of the second columnar rotating rod 18 is fixedly connected to a pushing rotating rod 114. On the side of the bottom of the pushing rotating rod 114 away from the second columnar rotating rod 18, a pushing block 116 is fixedly connected. On the side of the bottom of the pushing rotating rod 114 aligned with the second columnar rotating rod 18, a positioning rotating disc 115 is fixedly connected. On the side of the outer wall of the bottom of the columnar rotating rod 17 aligned with the positioning rotating disc 115, an irregular control rotating disc 117 is fixedly connected. The bottom end of the columnar rotating rod 17 is fixedly connected to the middle of the top of the inner rotating disc 28. The irregular control rotating disc 117 includes an irregular control rotating disc main body 1171. Semi-circular grooves 1172 are annularly arranged on the outer wall of the irregular control rotating disc main body 1171. On one side of the outer wall of the irregular control rotating disc main body 1171 inside the opened semi-circular grooves 1172, abutment grooves 1173 are opened. The outer wall of the positioning rotating disc 115 is attached to the inside of one of the semi-circular grooves 1172 opened on the irregular control rotating disc main body 1171; When it is necessary to control the top of the console 2 to drive the multiple impeller adjustment mechanisms 3 to rotate, first start the motor 14. The output end of the motor 14 drives the drive disk 15 to rotate. Since the track 110 is sleeved on the outer walls of the drive disk 15 and the second drive disk 19, the second drive disk 19 will rotate as the drive disk 15 rotates. The rotation of the second drive disk 19 drives the rotation of the second columnar rotating rod 18. The rotation of the second columnar rotating rod 18 drives the rotation of the abutting rotating rod 114. The rotation of the abutting rotating rod 114 drives the rotation of the positioning turntable 115. When the positioning turntable 115 rotates to fit the inner side of the semi-circular groove 1172 opened on the irregular control turntable body 1171, at this time, the irregular control turntable 117 is in a static and non-rotating state. With the continuous output of the motor 14, the abutting rotating rod 114 rotates and turns to the inner wall of the abutting groove 1173 opened on the irregular control turntable body 1171 through the abutting block 116. At this time, the abutting block 116 slides on the inner wall of one of the abutting grooves 1173 opened on the irregular control turntable body 1171 and then abuts to drive the whole irregular control turntable body 1171 to rotate. Thus, the irregular control turntable body 1171 drives the columnar rotating rod 17 to rotate. While the columnar rotating rod 17 rotates, it drives the top of the console 2 to rotate, and further drives the multiple impeller adjustment mechanisms 3 on its top to rotate synchronously, so as to realize the periodic rotation of the console 2 driving the multiple impeller adjustment mechanisms 3. When one of the impeller adjustment mechanisms 3 rotates to the welding area of the welding robot arm 112, at this time, the welding robot arm 112 performs precise welding on it. After completing the welding operation of the impeller, the welding robot arm 112 will temporarily stop working and wait for the next impeller adjustment mechanism 3 to rotate to the welding area.

The adjusting component 38 includes an adjusting component bottom connecting disk 381. The top of the outer wall of the adjusting component bottom connecting disk 381 is fixedly connected with an adjusting component outer disk 382. The inner bottom of the inner wall of the adjusting component bottom connecting disk 381 is fixedly connected with inner sleeve ring connecting rods 383 in an annular array. The inner sides of the multiple inner sleeve ring connecting rods 383 are fixedly connected with an inner sleeve ring 384. The inner wall of the inner sleeve ring 384 is fixedly connected to the outer wall of the columnar rotating vertical rod of the adjusting component 36. The inner wall of the adjusting component outer disk 382 is rotatably connected with second gear rotating rods 3810 in an annular array. The outer ends of the multiple second gear rotating rods 3810 all extend to the outer wall of the adjusting component bottom connecting disk 381 and are all fixedly connected with second gears 3811. The outer walls of the multiple second gears 3811 are annularly engaged with the top of the tooth disk 35. The inner ends of the multiple second gear rotating rods 3810 are all fixedly connected with triangular rotating plates 389. The tops of the multiple triangular rotating plates 389 are all fixedly connected with impeller placement plates 3812. One side of each of the multiple impeller placement plates 3812 is fixedly connected with a guiding C-shaped block 3813. The sides of the multiple guiding C-shaped blocks 3813 away from the impeller placement plates 3812 are all fixedly connected with electric push rod connecting blocks 3814. The tops of the multiple electric push rod connecting blocks 3814 are all fixedly connected with electric push rods 3815.The tops of multiple electric push rods 3815 are fixedly connected with inverted L-shaped positioning plates 3817. On the side of multiple inverted L-shaped positioning plates 3817 close to the impeller placement plate 3812, inverted L-shaped positioning plate pull blocks 3816 are fixedly connected. The bottoms of the outer walls of multiple inverted L-shaped positioning plate pull blocks 3816 are slidably connected to the inner walls of multiple guiding C-shaped blocks 3813. Inside of multiple triangular rotating plates 389 are fixedly connected with spherical universal rotating shafts 388.

The top of the water pump main shaft sleeve disc 385 is fixedly connected with a water pump main shaft columnar sleeve rod 387. The bottom of the water pump main shaft sleeve disc 385 is fixedly connected to the top of the adjusting component columnar rotating vertical rod 36; When welding the impeller is required, first, the inner shafts of multiple impellers are sleeved on the outer walls of the bottoms of multiple water pump main shaft columnar sleeve rods 387 of the adjusting components 38 and supported by multiple water pump main shaft sleeve discs 385. Multiple groups of impellers are placed flat on the tops of multiple groups of impeller placement plates 3812. Then, by starting the electric push rods 3815 on one side of multiple groups of impeller placement plates 3812, multiple groups of inverted L-shaped positioning plate pull blocks 3816 are pulled to move downward to position multiple groups of impellers. After that, by starting the motor 14, the inner turntable 28 is controlled to drive the rotating disc 25 to rotate through multiple rotating disc inner connecting rods 26 on the outer wall, thereby driving multiple adjusting mechanism connecting blocks 27 to rotate. When the gear 37 at the bottom of one of the impeller adjusting mechanisms 3 rotates and meshes with multiple tooth blocks 24 fixed on the outer wall of the rotating groove disc 23, the adjusting component columnar rotating vertical rod 36 meshing with multiple tooth blocks 24 rotates, thereby driving the whole of the adjusting component 38 to rotate. When the whole of the adjusting component 38 rotates, at this time, the second gears 3811 at the outer ends of multiple second gear rotating rods 3810 mesh and rotate with the tooth disc 35, so that multiple triangular rotating plates 389 rotate and adjust inside the spherical universal rotating shaft connecting blocks 386 through the spherical universal rotating shafts 388, thereby driving the impellers on the tops of multiple groups of impeller placement plates 3812 to adjust the angles, ensuring that the welding positions of the impellers are accurately aligned and the angles of the whole impellers are adjusted uniformly. At this time, welding can be carried out through the welding robotic arm 112. After welding is completed, at this time, the motor 14 continues to start to control the welded impeller adjusting mechanism 3 to rotate out of the welding area, and rotates the impeller adjusting mechanism 3 connected by another adjusting mechanism connecting block 27 to mesh with multiple tooth blocks 24 and adjusts the impeller to the welding position for welding through the same adjusting method. Through the cyclic adjusting method, multiple impeller adjusting mechanisms 3 carry out welding operations in turn, eliminating the need for manual angle adjustment and position movement of the impellers by workers, greatly improving the welding efficiency of the impellers, and at the same time avoiding the safety hazards brought by manual welding and reducing the production cost.

[0023] The working principle of the present invention: When welding the impeller is required, first, place multiple impeller inner sleeves at the bottom of the outer wall of the columnar sleeve rod 387 of the water pump main shaft of multiple position adjustment components 38 and support them by multiple water pump main shaft sleeve discs 385. Then, place multiple groups of impellers flat on the tops of multiple groups of impeller placement plates 3812. Start the electric push rods 3815 on one side of multiple groups of impeller placement plates 3812 to pull the multiple inverted L-shaped positioning plate pulling blocks 3816 downward to position multiple groups of impellers. After that, start the motor 14. The output end of the motor 14 drives the transmission disc 15 to rotate. Since the crawler 110 is sleeved on the outer walls of the transmission disc 15 and the second transmission disc 19, the second transmission disc 19 will rotate as the transmission disc 15 rotates. The rotation of the second transmission disc 19 drives the rotation of the second columnar rotating rod 18. The rotation of the second columnar rotating rod 18 drives the rotation of the pushing rotating rod 114. The rotation of the pushing rotating rod 114 drives the rotation of the positioning turntable 115. When the positioning turntable 115 rotates to fit the inner side of the semi-circular groove 1172 opened on the irregular control turntable body 1171, at this time, the irregular control turntable 117 is in a static and non-rotating state. With the continuous output of the motor 14, the pushing rotating rod 114 rotates and the abutting block 116 turns to the inner wall of the abutting groove 1173 opened on the irregular control turntable body 1171. At this time, the abutting block 116 slides on the inner wall of one of the abutting grooves 1173 opened on the irregular control turntable body 1171 and then drives the whole irregular control turntable body 1171 to rotate. Thus, the irregular control turntable body 1171 drives the columnar rotating rod 17 to rotate. The rotation of the columnar rotating rod 17 controls the inner turntable 28 to drive the rotating disc 25 to rotate through multiple rotating disc inner connecting rods 26 on the outer wall, and then drives multiple position adjustment mechanism connecting blocks 27 to rotate. When the gear 37 at the bottom of one of the impeller position adjustment mechanisms 3 rotates and meshes with multiple tooth blocks 24 fixed on the outer wall of the groove disc 23, the position adjustment component columnar rotating vertical rod 36 meshing with multiple tooth blocks 24 rotates, and then drives the whole position adjustment component 38 to rotate. When the whole position adjustment component 38 rotates, at this time, the second gears 3811 at the outer ends of multiple second gear rods 3810 mesh and rotate with the tooth disc 35, so that multiple triangular rotating plates 389 rotate and adjust through the spherical universal rotating shafts 388 in the spherical universal rotating shaft connecting blocks 386, and then drive the impellers on the tops of multiple groups of impeller placement plates 3812 to adjust the angles, ensuring that the welding positions of the impellers are accurately aligned and the angle adjustments of the whole impellers are consistent. At this time, welding can be carried out through the welding robotic arm 112. After welding is completed, at this time, the motor 14 continues to start to control the impeller position adjustment mechanism 3 that has been welded to rotate out of the welding area, and rotate the impeller position adjustment mechanism 3 connected by another position adjustment mechanism connecting block 27 to mesh with multiple tooth blocks 24 and adjust the impeller to the welding position for welding through the same position adjustment method.
