Description

Technical Field

[0001] The present invention relates to the technical field of metal welding, and particularly to an adjustable metal welding processing device. Background Art

[0002] In the field of metal processing, especially in the manufacturing process of products such as industrial fans, the welding process of the fan blade and the fan base is crucial. Among them, the fan base is integrally cylindrical, and a connecting shaft is fixedly connected to the center of the inner top thereof. A screw hole for subsequent connection with the fan motor shaft is provided on the connecting shaft.

[0003] During the welding process of multiple fan blades to the fan base, both the fan base and the multiple fan blades need to be fixed in position by jigs, and one end of the multiple fan blades is made to fit outside the fan base and combined with the fan base to form a prototype of a fan blade. Subsequently, a welding robot performs multi-directional welding on the multiple fan blades and the fan base.

[0004] However, the position fixation of each fan blade relative to the fan base requires operating the corresponding jig to fix the fan blade. Moreover, after the multiple fan blades are welded outside the fan base, it is also necessary to sequentially loosen the jigs at the corresponding multiple fan blades and the jigs at the corresponding fan base, and the operation is relatively cumbersome, affecting the welding efficiency. At the same time, in the actual welding scenario, different welding requirements will be encountered, that is, the angles of the fan blades relative to the fan base are different. After each fan blade is fixed in position by the existing jig, each fan blade cannot be adjusted synchronously in angle, which has limitations and brings inconvenience to welding work with different requirements.

[0030] Embodiment 1: Please refer to Figure 1 - Figure 11, An adjustable metal welding processing device in the illustration includes a frame 1, a welding robot 2 installed on the frame 1, and a carrier plate 3 rotatably arranged on the frame 1.

A jacking mechanism is provided at the lower end of the carrier plate 3.

[0031] The clamping mechanism includes two arc-shaped grooves 20, which are respectively opened at the two side edges of the arc-shaped surface of the arc-shaped plate 7. The inner walls of the two arc-shaped grooves 20 are both attached to arc-shaped blocks 27.

Arc-shaped rods 23 are slidably inserted through the inner walls of the two arc-shaped blocks 27. The two arc-shaped rods 23 are respectively fixedly connected to the inner walls of the two arc-shaped grooves 20. Arc-shaped springs 25 are slidably sleeved on the outer walls of the two arc-shaped rods 23. One ends of the two arc-shaped springs 25 are respectively fixedly connected to the wall surfaces of the two arc-shaped blocks 27 away from each other, and the other ends of the two arc-shaped springs 25 are respectively fixedly connected to the inner walls of the two arc-shaped grooves 20 away from the arc-shaped blocks 27. Triangular blocks 21 are fixedly connected to the ends of the two arc-shaped blocks 27 away from the cylinder body 5, and a limiting mechanism is provided between the upper ends of the two arc-shaped blocks 27 and the blade 9.

[0032] The limiting mechanism includes two round blocks 22, which are symmetrically fixedly connected to the upper edge of the wall surface of the arc-shaped block 27 corresponding to the arc-shaped spring 25. A connecting column 28 is rotatably connected between the two round blocks 22. A collar 24 is rotatably sleeved in the middle of the outer wall of the connecting column 28. Torsion springs 26 are fixedly connected between the two ends of the collar 24 and the two round blocks 22 respectively. The two torsion springs 26 are both slidably sleeved on the outer wall of the connecting column 28. A pressing plate 18 is fixedly connected to the outer wall of the collar 24. The bottom end of the pressing plate 18 is closely attached to the outer surface of the blade 9.

[0033] The fixing mechanism includes a square groove 37 which is penetrated and opened at the upper end of the cylinder body 5 near the edge, and the inner wall of the square groove 37 is attached with a U-shaped plate 33. A plug post 29 is fixedly penetrated through the inner wall of the U-shaped plate 33. One end of the plug post 29 is slidably inserted into the hole wall of the central connecting shaft of the fan base 8. And a first magnetic block 30 is fixedly connected to the bottom of the outer wall of the plug post 29 near the central connecting shaft of the fan base 8. And a connecting plate 34 is slidably sleeved on the outer wall of the plug post 29 away from the edge of the fan base 8. The connecting plate 34 is fixedly connected to the inner top edge of the cylinder body 5. And a second spring 35 is fixedly connected between the connecting plate 34 and the U-shaped plate 33. The second spring 35 is slidably sleeved on the outer wall of the plug post 29. A pulling mechanism is arranged between the U-shaped plate 33 and the cylinder body 5.

[0034] The pulling mechanism includes an L-shaped plate 32 and a rectangular groove 36. The rectangular groove 36 is opened at the upper end of the cylinder body 5 corresponding to the square groove 37. The L-shaped plate 32 is fixedly connected to the top end of the U-shaped plate 33. And the L-shaped plate 32 and the rectangular groove 36 are slidably matched.

[0035] The jacking mechanism includes an electric push rod 19. The electric push rod 19 is fixedly installed at the center of the bottom end of the carrier plate 3. And the telescopic shaft of the electric push rod 19 movably penetrates through the upper end of the carrier plate 3. And a second magnetic block 31 is fixedly connected to the outer surface of the telescopic shaft of the electric push rod 19 corresponding to the first magnetic block 30. The second magnetic block 31 and the first magnetic block 30 have the same magnetic poles.

[0036] In this embodiment, first, place the fan base 8 on the cylinder body 5, and pass the connecting shaft on the fan base 8 through the hole groove on the cylinder body 5 (at this time, the bottom end of the connecting shaft on the fan base 8 will be attached to the outer wall of the plug post 29). Subsequently, pull the L-shaped plate 32 in the direction away from the fan base 8. The L-shaped plate 32 will slide in the rectangular groove 36 on the cylinder body 5 in the direction away from the fan base 8. And the L-shaped plate 32 will drive the U-shaped plate 33 to slide in the square groove 37 on the cylinder body 5 in the direction away from the fan base 8. The U-shaped plate 33 will drive the plug post 29 to move in the inner wall of the connecting plate 34 (in this process, the second spring 35 between the U-shaped plate 33 and the connecting plate 34 will be compressed on the outer wall of the plug post 29). When the plug post 29 leaves the bottom end of the connecting shaft on the fan base 8, under the action of gravity, the fan base 8 will be attached to the upper end of the cylinder body 5. Subsequently, rotate the fan base 8. When the hole groove on the connecting shaft of the fan base 8 corresponds to the position of the plug post 29, then under the action of the second spring 35, the plug post 29 will automatically reset and be inserted into the hole groove on the connecting shaft of the fan base 8. At this time, the fan base 8 can be fixedly installed on the cylinder body 5.

[0037] Subsequently, insert a blade 9 onto the upper surface of any one of the arc-shaped plates 7 such that the end of the blade 9 abuts against the outer wall of the fan base 8. When the blade 9 is inserted onto the upper surface of the arc-shaped plate 7, the end of the blade 9 will abut against the two triangular blocks 21, causing the two triangular blocks 21 to move away from each other within their respective corresponding arc-shaped grooves 20 on the arc-shaped plate 7. The two triangular blocks 21 will drive the arc-shaped blocks 27 on them to move away from each other within their respective corresponding arc-shaped grooves 20. The two arc-shaped blocks 27 will also slide away from each other on the outer walls of their respective corresponding arc-shaped rods 23. During this process, the arc-shaped springs 25 between the two arc-shaped blocks 27 and their respective corresponding arc-shaped grooves 20 will be compressed on the outer walls of their respective corresponding arc-shaped rods 23. At this time, under the action of the two arc-shaped springs 25, the blade 9 will be clamped tightly by the two arc-shaped blocks 27.

[0038] When the blade 9 is inserted onto the arc-shaped plate 7, due to the certain thickness of the blade 9 itself, the blade 9 will also slightly lift the two pressure plates 18 by a small distance. During this process, the two pressure plates 18 will drive the collar rings 24 on them to rotate on the outer walls of their respective corresponding connecting columns 28. The two collar rings 24 will drive the two torsion springs 26 on them to be further twisted. Then, under the action of the two torsion springs 26, the blade 9 will also be clamped tightly between the arc-shaped surface of the arc-shaped plate 7 and the lower ends of the two pressure plates 18. Then, the blade 9 can be fixed on the corresponding arc-shaped plate 7. Similarly, by following the same operation, the remaining five blades 9 can be fixed on their respective corresponding arc-shaped plates 7. Finally, start the welding robot 2 on the frame 1 to successively weld the six blades 9 onto the fan base 8 (the welding operation process and welding method of the welding robot 2 are both well-known prior arts and will not be elaborated).

[0039] After the welding is completed, start the electric push rod 19 on the carrier plate 3. The telescopic shaft of the electric push rod 19 will move upward, and the magnet block two 31 on the telescopic shaft of the electric push rod 19 will also move upward accordingly. When the magnet block two 31 corresponds to the position of the magnet block one 30 on the plug post 29, due to the like poles repelling each other, the magnet block one 30 will move away from the magnet block two 31 (the repulsive force between the magnet block one 30 and the magnet block two 31 is greater than the elastic force of the spring two 35). The magnet block one 30 will drive the plug post 29 to leave the hole groove on the connecting shaft of the fan base 8. As the telescopic shaft of the electric push rod 19 continues to move upward, the bottom end of the fan base 8 can leave the upper end of the cylinder body 5, and the fan base 8 will drive the six welded blades 9 on it to move upward together. The six blades 9 will drive the two pressure plates 18 on them to rotate during the upward movement (although the two torsion springs 26 corresponding to each pressure plate 18 will be further twisted, it does not affect the upward movement of the blade 9). When the six blades 9 completely leave the two pressure plates 18 corresponding to them, then under the action of the two torsion springs 26 corresponding to each, each pressure plate 18 can automatically reset. Subsequently, turn off the electric push rod 19 and directly take away the welded fan base 8 and the six blades 9 together.

[0040] Embodiment 2: Please refer to Figure 1 - Figure 5 , Figure 8 and Figure 10 , this embodiment further illustrates Embodiment 1. In the illustration, the angle adjustment mechanism includes an annular plate 6, six rubber columns 12, a motor 38 and an arc-shaped rack 40. The annular plate 6 is rotatably sleeved on the outer wall of the cylinder body 5, and a ring 13 is elastically arranged above the annular plate 6 through an elastic mechanism. The upper end of the ring 13 is fixedly connected with a rubber ring 14. The six rubber columns 12 are respectively fixedly connected to one end of the six rotating shafts 10 corresponding to the cylinder body 5, and the outer walls of the six rubber columns 12 are all in close contact with the upper end of the rubber ring 14. A plurality of arc-shaped grooves 17 are formed in an annular array around the center of the upper end of the rubber ring 14. The motor 38 is fixedly installed at the upper edge of the carrier plate 3, and the output shaft end of the motor 38 is fixedly connected with a gear 39. The arc-shaped rack 40 is fixedly embedded in the outer wall of the annular plate 6 corresponding to the gear 39, and the arc-shaped rack 40 meshes with the gear 39.

[0041] The elastic mechanism includes a plurality of guide columns 15. The plurality of guide columns 15 are fixedly connected to the lower end of the ring 13 in an annular array around the center of the ring 13, and the plurality of guide columns 15 all movably penetrate through the bottom end of the annular plate 6. A first spring 16 is slidably sleeved on the outer walls of the plurality of guide columns 15, and the plurality of first springs 16 are all fixedly connected between the upper end of the annular plate 6 and the lower end of the ring 13.

[0042] In this embodiment, when it is necessary to synchronously adjust the angle between the fan base 8 and the six blades 9, before welding operation, first, start the motor 38 on the carrier plate 3. The output shaft of the motor 38 will rotate and drive the gear 39 to rotate. The gear 39 will drive the arc-shaped rack 40 to rotate. The arc-shaped rack 40 will drive the annular plate 6 to rotate on the outer wall of the cylinder body 5. The annular plate 6 will drive the plurality of guide columns 15 thereon to rotate together. The plurality of guide columns 15 will jointly drive the ring 13 to rotate. The ring 13 will drive the rubber ring 14 to rotate. The rubber ring 14 will drive the six rubber columns 12 thereon to rotate. The six rubber columns 12 will drive the respective rotating shafts 10 on them to rotate on the respective supporting plates 4. The six rotating shafts 10 will drive the respective connecting blocks 11 thereon to rotate together. The six connecting blocks 11 can drive the respective arc-shaped plates 7 thereon to rotate together. Then the six arc-shaped plates 7 can rotate together, so as to realize synchronous adjustment of the angle between the fan base 8 and the six blades 9.

[0043] It should be noted that when the six rubber columns 12 rotate on the rubber ring 14, the six rubber columns 12 will all pass through the respective corresponding arc-shaped grooves 17 on the rubber ring 14. The setting of the arc-shaped grooves 17 can increase the friction between the rubber columns 12 and the rubber ring 14. At the same time, under the action of the plurality of first springs 16 between the annular plate 6 and the ring 13, the upper surface of the ring 13 will always be in close contact with the outer wall of the rubber ring 14.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
