[0021] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a flange water pipe welding device for air conditioning is described as follows.

[0022] include: The base 1 has screws 2 evenly arranged on its outer wall; The fixing mechanism 3 has an inner wall connected to the outer wall of the screw rod 2 by threads; A feeding mechanism 4 is provided on the outer wall of the fixing mechanism 3; The flange water pipe welding equipment for air conditioners also includes: The pipe delivery mechanism 5 is provided at the end of the screw 2 away from the base 1, and a pipe 6 is provided inside the pipe delivery mechanism 5; The flange 7 is arranged on a side of the fixing mechanism 3 close to the pipe feeding mechanism 5, and the flange 7 contacts one end of the pipe 6; A driving ring 8, the inner wall of the driving ring 8 is slidably connected to the outer wall of the screw 2; The welding head 9 is installed on the side of the driving ring 8 close to the flange 7, and the outer wall of the welding head 9 is slidably connected to the outer wall of the driving ring 8.

[0023] During work, the worker inserts the pipe 6 from the pipe feeding mechanism 5, puts the flange 7 into the feeding mechanism 4, and enables the pipe feeding mechanism 5 to insert the pipe 6 and keep the pipe 6 horizontal with the assistance of the fixing mechanism 3. The feeding mechanism 4 sends the flange 7 to the fixing mechanism 3 for fixing, so that the flange 7 is consistent with the axis of the pipe 6. The feeding mechanism 4 grinds and cleans one end of the pipe 6 and the outer wall, and then the welding head 9 slides on the outer wall of the driving ring 8 to weld the gap between the flange 7 and the pipe 6. After welding is completed, the pipe feeding mechanism 5 reverses and transports the pipe 6 outward, and the worker takes out the welded product.

[0024] The feeding mechanism 4 comprises: Telescopic column 401, which is installed on the top of the fixing mechanism 3; A positioning plate 402 is mounted on the end of the telescopic column 401 away from the fixing mechanism 3. A groove 405 is formed on the center axis of the positioning plate 402 near the telescopic column 401. A grinding assembly 403 is provided on a side of the positioning plate 402 away from the telescopic column 401; The positioning assembly 404 is installed on a side of the positioning plate 402 away from the grinding assembly 403 .

[0025] At the beginning, the worker places the flange 7 along the positioning component 404, and then the positioning component 404 automatically aligns the axis of the flange 7 with the axis of the positioning plate 402. Then, driven by the telescopic column 401, the positioning plate 402 is moved to a position that coincides with the axis of the fixing mechanism 3, and the flange 7 is placed on the fixing mechanism 3 and fixed. Then, the pipe feeding mechanism 5 brings the pipe 6 close to the grinding component 403, so that the grinding component 403 grinds and cleans the end and outer wall of the pipe 6. The telescopic column 401 then moves the positioning plate 402 outward to make the pipe 6 contact with the flange 7 before welding. The pipe 6 and the flange 7 before welding are pre-treated so that the surfaces of the pipe 6 and the flange 7 can be kept flat and free of debris before welding, so as to avoid debris affecting the connection of the weld during welding, so that the flange 7 can be automatically aligned and fixed with the pipe 6 when loading, reducing manual operation steps and saving loading and fixing time.

[0026] The fixing mechanism 3 comprises: The movable seat 301 has an inner wall threadedly connected to the outer wall of the screw 2, and a central hole 304 is formed at the central axis of the movable seat 301; The card blocks 302 are evenly arranged on one side of the movable seat 301 close to the positioning assembly 404. The outer wall of the card blocks 302 is slidably connected to the outer wall of the movable seat 301. There are three card blocks 302, and their positions avoid the moving path of the feeding mechanism 4.

[0027] The fixing mechanism 3 also includes: Cylinder 303, which is disposed on a side of the movable base 301 away from the clamping block 302, and extends along the central hole 304 to a side of the movable base 301 close to the clamping block 302; The support assembly 305 is arranged at one end of the cylinder 303 close to the block 302 , and is used to support the inner wall of the pipeline 6 and the flange 7 .

[0028] When the feeding mechanism 4 moves the flange 7 to the axis of the movable seat 301, the clamping block 302 moves along the movable seat 301, approaches the flange 7, clamps the flange 7 from the outside, and feeds the flange 7 to separate from the feeding mechanism 4. Then the cylinder 303 drives the supporting assembly 305 to pass through the movable seat 301, so that the supporting assembly 305 is inserted into the middle of the flange 7 and enters the interior of the pipe 6 to support the pipe 6 and the flange 7, so that the flange 7 and the pipe 6 can fit better, increase the support for the pipe 6, ensure that the pipe 6 and the flange 7 can remain relatively stable during welding, and keep close fit, thereby improving the accuracy of the weld.

[0029] The delivery mechanism 5 includes: The connecting seat 501 is provided at the end of the screw 2 away from the base 1, and the end of the screw 2 away from the base 1 is rotatably connected to the outer wall of the connecting seat 501; The second telescopic rod 502 is evenly arranged on the inner wall of the connecting seat 501; A movable frame 503, wherein an outer wall of the movable frame 503 is connected to one end of the second telescopic rod 502; The rollers 504 are evenly arranged on the inner wall of the movable frame 503 , and the outer wall of the rollers 504 is rotatably connected to the inner wall of the movable frame 503 .

[0030] Initially, the pipe 6 is inserted into the center hole 304 of the connecting seat 501. At this time, the second telescopic rod 502 is extended, driving the roller 504 to contact the outer wall of the pipe 6. The roller 504 rotates to enable the pipe 6 to enter and be sent out horizontally. When the pipe 6 approaches the flange 7, the support assembly 305 is inserted into the interior of the pipe 6 to support the pipe 6 from both ends during welding to keep the pipe 6 stable.

[0031] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on Example 1, the support assembly 305 includes: Mounting plate 3051, which is disposed at one end of the cylinder 303 near the clamping block 302; The arc-shaped rods 3052 are evenly arranged on the inner wall of the mounting plate 3051. The outer wall of the arc-shaped rods 3052 is rotatably connected to the inner wall of the mounting plate 3051. The arc-shaped rods 3052 are used to support the pipe 6 and the flange 7 from the inside, so that the connection gap between the pipe 6 and the flange 7 is easy to align; The airbags 3053 are arranged at both ends of the arc rod 3052.

[0032] In the process of bringing the pipe 6 close to the flange 7, the mounting plate 3051 drives the arc rod 3052 to a horizontal state, so that the air bags 3053 at both ends of the arc rod 3052 contact the inner wall of the pipe 6 with the inner wall of the flange 7. The two ends of the arc rod 3052 keep the inner wall of the pipe 6 and the inner wall of the flange 7 at the same height, so that the flange 7 and the pipe 6 are kept at the same height, ensuring the relative position between the flange 7 and the pipe 6 and avoiding displacement during welding.

[0033] The grinding assembly 403 includes: Motor 4031, motor 4031 is arranged at the central axis of positioning plate 402; A fixing frame 4032 , the fixing frame 4032 being arranged on an outer wall of the motor 4031 ; The grinding ring 4033 is arranged on the outer wall of the fixing frame 4032. The grinding ring 4033 is used to grind the end of the pipe 6 so that the pipe 6 can maintain a flush position with the flange 7 before welding.

[0034] The grinding assembly 403 further includes: The fixing plate 4034 is symmetrically arranged on the edge of the positioning plate 402, and the outer wall of the fixing plate 4034 is slidably connected to the outer wall of the positioning plate 402; Push rod 4035, push rod 4035 is arranged on the inner wall of fixed plate 4034; The splint 4036 is disposed at one end of the push rod 4035 away from the fixed plate 4034. The splint 4036 is shaped like an "X". The polishing assembly 403 of the splint 4036 further includes: A grinding sheet 4037 is provided on the outer wall of the clamping plate 4036 and is used to pre-treat the outer wall of the end of the pipe 6 to make the outer surface of the pipe 6 smooth and flat; A movable rod 4038 is provided on the outer wall of the clamping plate 4036 , and one end of the movable rod 4038 is rotatably connected to the outer wall of the clamping plate 4036 ; The wiping block 4039 has an outer wall that is rotatably connected to the other end of the movable rod 4038 . The wiping block 4039 is used to clean the outer wall of the pipe 6 and remove dust and debris from grinding.

[0035] After the positioning plate 402 moves to a position flush with the axis of the movable seat 301, the pipe feeding mechanism 5 brings the end of the pipe 6 into contact with the grinding ring 4033, and then the motor 4031 drives the grinding ring 4033 to rotate to grind the edge of the pipe 6. The positioning plate 402 drives the push rod 4035 to rotate along the periphery of the pipe 6, and at the same time drives the splint 4036 to move close to the outer wall of the pipe 6, so that the grinding sheet 4037 contacts the outer wall of the pipe 6 and grinds the outer wall of the pipe 6 during the rotation process. The splint 4036 drives the movable rod 4038 to rotate, so that the wiping block 4039 contacts the outer wall of the pipe 6, cleans the outer wall of the pipe 6, and cleans the powder generated by grinding and the debris on the outer wall of the pipe 6 before welding, so as to avoid the debris from affecting the weld and affecting the welding effect.

[0036] Positioning component 404 includes: A lifting column 4041 is installed on the inner wall of the groove 405; First telescopic rods 4042 , the first telescopic rods 4042 are evenly arranged on the outer wall of the lifting column 4041 ; An anti-sliding block 4043 is provided at an end of the first telescopic rod 4042 away from the lifting column 4041; A limiting sleeve 4044 is provided on the outer wall of the positioning plate 402; Elastic rods 4045 are evenly arranged on the inner wall of the limiting housing 4044. The elastic rods 4045 support flanges 7 of different specifications, so that smaller flanges 7 produce less deformation on the elastic rods 4045, so that the center of the flange 7 remains close to the central axis of the positioning plate 402; The arc frame 4046 is installed at one end of the elastic rod 4045 away from the limiting housing 4044.

[0037] At the beginning, the worker puts the flange 7 into the limiting sleeve 4044, so that the flange 7 slides downward under the action of gravity, contacts the arc frame 4046, and is buffered by the elastic force of the elastic rod 4045, and keeps the axis of the flanges 7 of different specifications close to the axis of the positioning plate 402. Then the lifting column 4041 is extended, so that the first telescopic rod 4042 is in the middle of the flange 7. After the first telescopic rod 4042 is extended, the anti-sliding block 4043 is in contact with the inner wall of the flange 7, so that the axis of the flange 7 overlaps with the axis of the positioning plate. Driven by the telescopic column 401, the axis of the positioning plate is coincided with the axis of the movable seat 301, which facilitates the placement of the flange 7 on the fixing mechanism 3, reduces the time for workers to install and fix the flange 7, and improves welding efficiency.

[0038] The specific workflow is as follows: During operation, at the beginning, the worker places the flange 7 along the positioning assembly 404, and then the positioning assembly 404 automatically aligns the axis of the flange 7 with the axis of the positioning plate 402. Then, driven by the telescopic column 401, the positioning plate 402 is moved to a position that coincides with the axis of the fixing mechanism 3, and the flange 7 is placed on the fixing mechanism 3 and fixed. Then, the pipe delivery mechanism 5 brings the pipe 6 close to the polishing assembly 403, so that the polishing assembly 403 polishes and cleans the end and outer wall of the pipe 6. The telescopic column 401 then moves the positioning plate 402 outward, so that the pipe 6 contacts the flange 7, and the axes of the flange 7 and the pipe 6 are aligned. When the feeding mechanism 4 moves the flange 7 to the axis of the movable seat 301, the clamping block 302 moves along the movable seat 301, approaches the flange 7, clamps the flange 7 from the outside, and feeds the material so that the flange 7 is separated from the feeding mechanism 4. Then the cylinder 303 drives the supporting assembly 305 to pass through the movable seat 301, so that the supporting assembly 305 is inserted into the middle of the flange 7 and enters the interior of the pipe 6 to support the pipe 6 and the flange 7, so that the flange 7 and the pipe 6 can fit better, increase the support for the pipe 6, and ensure that the pipe 6 and the flange 7 can maintain relative stability during welding; Initially, the pipe 6 is inserted into the center hole 304 of the connecting seat 501. At this time, the second telescopic rod 502 is extended, driving the roller 504 to contact the outer wall of the pipe 6. The roller 504 rotates to enable the pipe 6 to enter and be sent out horizontally. When the pipe 6 approaches the flange 7, the support assembly 305 is inserted into the interior of the pipe 6 to support the pipe 6 from both ends during welding to keep the pipe 6 stable. Then the welding head 9 slides on the outer wall of the drive ring 8 to weld the gap between the flange 7 and the pipe 6. After welding is completed, the pipe feeding mechanism 5 reverses and transports the pipe 6 outward, and the worker takes out the welded product.
