Description

Technical Field

[0001] This invention relates to the field of welding the inner wall of hollow steel frames, and more particularly to an automated welding equipment for the inner wall of a support-type hollow steel frame in a factory. Background Technology

[0002] Hollow steel frames are a common type of steel structure used in factory building support systems, primarily for load-bearing and support. They are constructed by assembling hollow-section steel components (such as square, round, and rectangular tubes) through welding, bolting, and other methods to form a stable frame structure.

[0003] In the construction of hollow steel frame factory buildings, U-shaped support frames are usually welded to the outer wall of the hollow steel frame and inner steel plates are welded to the inside of the hollow steel frame to facilitate the support of the crossbeams. Then, the U-shaped support frames and inner steel plates are connected by hexagonal bolts to enhance the stability of the U-shaped support frames.

[0004] However, during the welding of the inner steel lining plate, the narrow internal space of the hollow steel frame makes it difficult to operate accurately by manual welding, which can easily lead to unstable weld quality.

[0021] The first rack is slidably guided and installed in the welded square seat, and meshes with the first gear;

[0022] The transmission component moves during the flipping process of the flipping rod, thereby driving the first rack to make linear motion within the welding seat.

[0023] Preferably, the transmission assembly includes:

[0024] The second rack is fixedly connected to the top of the first rack;

[0025] The second gear is rotatably connected to the rotating shaft of the flipping rod. The rotating shaft of the flipping rod has an arc-shaped groove on its surface. An arc-shaped slide rod is fixedly connected in the arc-shaped groove. A slider is fixedly connected to the inner wall of the second gear. The slider is slidably connected in the arc-shaped slide rod. The two ends of the arc-shaped spring are fixedly connected to the arc-shaped groove and the slider, respectively.

[0026] Preferably, it also includes a sliding plate, which is slidably connected to the welding square base. Multiple connecting plates are fixedly connected to the side wall of the sliding plate, and the connecting plates are slidably connected to the welding square base.

A second cylinder is fixedly connected to the top of the U-shaped seat, and the bottom end of the telescopic rod of the second cylinder is fixedly connected to the second positioning plate.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] I. This invention, by setting up a welding base, a synchronous belt, and a synchronous pulley, and by setting a predetermined trajectory for the welding torch, namely the rotation trajectory of the synchronous belt, facilitates welding in narrow spaces, improves welding quality, eliminates the need for manual welding, reduces labor intensity, and increases welding efficiency.

[0035] II. This invention, by setting up a rotating sleeve and a rotation drive assembly, causes the rotating shaft of the rotating rod to rotate synchronously during the flipping process, thereby causing the second gear to rotate. Since the second gear meshes with the second rack, it drives the second rack to move, and the first rack moves. The movement of the first rack drives the first gear to rotate, thereby causing the drive seat to rotate. Under the connecting action of the connecting rod, the rotating sleeve rotates, thereby causing the hexagonal bolt to rotate, ensuring that the hexagonal bolt is tightened. On the one hand, by tightening the hexagonal bolt, a downward squeezing effect is exerted on the inner lining steel plate, further reducing the gap between the inner lining steel plate and the steel frame and improving the welding quality. On the other hand, it realizes the automatic tightening of the hexagonal bolt.

[0036] Third, this invention, by setting up a sliding plate, a connecting plate, and a threaded rod, allows manual rotation after welding to cause the threaded rod to rotate. Under the action of the threaded connection, the sliding plate moves upward, thereby causing multiple rotating sleeves to move upward and disengage from the hexagonal bolts. This ensures that the rotating sleeves will not loosen or loosen the hexagonal bolts during the resetting process of the flipping rod, thus ensuring that the hexagonal bolts are in a tightened state after welding. This helps to reduce the difficulty of installation, which requires manually tightening the hexagonal bolts in the narrow space inside the steel frame.

[0037] Fourth, in this invention, the second gear is rotatably connected to the rotating shaft of the flipping rod 18, and an arc spring is set between the two. After the hexagonal bolts are fully tightened, the flipping rod can continue to rotate, thereby continuously pressing the inner lining steel plate downward, so that the gap between the inner lining steel plate and the steel frame is minimized as much as possible, ensuring the welding quality while avoiding the impact of tightening the hexagonal bolts on the welding.

[0047] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0048] like Figures 1 to 8 The automated welding equipment for the inner wall of a hollow steel frame in a factory building includes: a machine tool 1, with a positioning component at the top of the machine tool 1 for clamping and positioning the outer wall of the steel frame 2; a welding square base 10, with a threaded sleeve assembly at the bottom of the welding square base 10 that matches multiple hexagonal bolts 301 on the inner lining steel plate 4; four synchronous pulleys 11, which are rotatably connected to the four corner grooves of the welding square base 10, and a synchronous belt 12 is sleeved on the surface of the four synchronous pulleys 11; a drive motor 13, which is fixedly connected to the welding square base 10, and the output shaft of the drive motor 13 is coaxially fixed with the synchronous pulleys 11 at the corresponding positions; and a fixing plate 14, which is fixedly connected to the synchronous belt 12, with a fixing block 15 fixedly connected to the end of the fixing plate 14, and a welding torch 16 (the welding torch 16 is inclined towards the direction of welding between the inner lining steel plate 4 and the steel frame 2) at the bottom of the fixing block 15.

[0049] In the existing technology, during the welding of the inner steel plate 4, the narrow internal space of the hollow steel frame 2 makes it difficult to operate accurately by manual welding, which easily leads to unstable weld quality. This technical solution can solve the above problems. The specific operation is as follows:

[0050] First, place the steel frame 2 to be welded on the machine tool 1, and then clamp and position the steel frame 2 using the positioning assembly to ensure the stability of the steel frame 2 during the welding process;

[0051] The inner steel plate 4 is then connected to the hexagonal bolts 301, and then the hexagonal bolts 301 are connected to the threaded sleeve assembly to limit the welding square seat 10.

[0052] Next, the welding square base 10 and the inner steel plate 4 are placed into the steel frame 2, and the hex bolts 301 are inserted into the holes and slots on the steel frame 2.

[0053] After the installation of the welding base 10 is completed, the drive motor 13 is started, and the output shaft of the drive motor 13 is rotated, which drives the synchronous pulley 11 to rotate. Under the drive of the synchronous pulley 11, the synchronous belt 12 is rotated, which drives the fixed plate 14 to rotate. The fixed block 15 drives the welding gun 16 to move along the edge of the inner steel plate 4. During the movement, the welding gun 16 is started to weld, thereby welding the inner steel plate 4 to the inner wall of the steel frame 2.

[0054] By setting the predetermined trajectory of the welding torch 16, i.e. the rotation trajectory of the synchronous belt 12, the welding torch 16 can be used for welding in narrow spaces, improving welding quality and eliminating the need for manual welding, thus reducing labor intensity and improving welding efficiency.

[0055] As a further embodiment of the present invention, the entire welding equipment also includes two rotating seats 17, which are symmetrically and fixedly connected to the top of the welding square seat 10. A flipping rod 18 is rotatably connected inside the rotating seat 17. A flipping frame 19 is slidably connected to the top of the flipping rod 18 (the flipping frame 19 can slide relative to the length direction of the flipping rod 18). A roller 20 is rotatably connected to the top of the flipping frame 19. A compression spring 21 is fixedly connected between the flipping frame 19 and the flipping rod 18.

[0056] Two servo motors 22 are symmetrically fixedly connected to the top of the welding base 10, and the output shaft of the servo motor 22 is coaxially fixed with the flip rod 18 at the corresponding position.

[0057] After the welding base 10 is placed inside the steel frame 2, two servo motors 22 are started (one rotates forward and the other in reverse). The servo motors 22 drive the two rotating rods 18 to rotate toward each other. The rotation of the rotating rods 18 will cause the rotating frame 19 to rotate, so that the roller 20 at the top of the rotating frame 19 contacts the top of the inner wall of the steel frame 2. The top of the inner wall of the steel frame 2 reacts to the rotating frame 19, causing the rotating frame 19 to move toward the rotating rods 18 (i.e., retract). The compression spring 21 is compressed and generates elastic force, which in turn generates a downward thrust on the welding base 10, thereby increasing the contact force between the inner lining steel plate 4 and the inner wall of the steel frame 2. This ensures that the inner lining steel plate 4 and the steel frame 2 are in full contact during the welding process, reduces the gap between the inner lining steel plate 4 and the steel frame 2, and thus improves the welding quality.

[0058] As a further embodiment of the present invention, the screw sleeve assembly in this embodiment includes a rotating screw sleeve 23, which is slidably connected to the bottom end of the welding square seat 10 (that is, the rotating screw sleeve 23 can move relative to the thickness direction of the welding square seat 10). A rotation drive assembly is provided inside the welding square seat 10, which is used to drive the rotating screw sleeve 23 to rotate in order to tighten the hexagonal bolt 301.

[0059] Specifically, the rotation drive component in this embodiment includes:

[0060] The drive seat 24 is rotatably installed in the welding square seat 10 in the horizontal direction (that is, the drive seat 24 can only rotate in the horizontal direction relative to the welding square seat 10, but the two do not produce relative displacement in the vertical direction). Several connecting rods 25 are slidably connected to the bottom end of the drive seat 24 in the circumferential direction. The bottom end of the connecting rods 25 is fixedly connected to the top end of the rotating screw sleeve 23. That is, the rotating screw sleeve 23 moves in the vertical direction relative to the drive seat 24 through the connecting rods 25.

[0061] The first gear 26 is fixedly sleeved on the top of the drive seat 24;

[0062] The first rack 27 is slidably guided and installed inside the welded square seat 10, and meshes with the first gear 26;

[0063] The transmission component is driven to move during the flipping of the flipping rod 18, so as to drive the first rack 27 to make linear motion within the welding square seat 10.

[0064] Furthermore, the transmission assembly in this embodiment includes:

[0065] The second rack 28 is fixedly connected to the top of the first rack 27;

[0066] The second gear 29 is rotatably connected to the rotating shaft of the flipping rod 18. The rotating shaft of the flipping rod 18 has an arc-shaped groove 30. An arc-shaped sliding rod 31 is fixedly connected inside the arc-shaped groove 30. A slider 32 is fixedly connected to the inner wall of the second gear 29. The slider 32 is slidably connected to the arc-shaped sliding rod 31. The two ends of the arc-shaped spring 33 are fixedly connected to the arc-shaped groove 30 and the slider 32, respectively.

[0067] It should be noted that in this embodiment, the second gear 29 can be directly fixed to the rotating shaft of the flipping rod 18. In this way, during the flipping process of the flipping rod 18, the second gear 29 rotates synchronously with it. The second gear 29 meshes with the second rack 28, thereby driving the second rack 28 to move and the first rack 27 to move. The movement of the first rack 27 drives the first gear 26 to rotate, thereby causing the drive seat 24 to rotate. Under the connection of the connecting rod 25, the rotating sleeve 23 rotates, thereby causing the hexagonal bolt 301 to rotate and perform the tightening operation on the hexagonal bolt 301. The above structure, on the one hand, exerts a downward squeezing effect on the inner lining steel plate 4 by tightening the hexagonal bolt 301, further reducing the gap between the inner lining steel plate 4 and the steel frame 2 and improving the welding quality. On the other hand, it realizes the automatic tightening of the hexagonal bolt 301.

[0068] The reason why this embodiment chooses to rotatably connect the second gear 29 to the rotating shaft of the flipping rod 18 is mainly due to the fact that the flipping angle of the flipping rod 18 allows the tightening of the hexagonal bolt 301 and the compression of the inner lining steel plate 4 to a certain extent to achieve independent operation. Specifically, as shown in the figure... Figure 6 , 7As shown, in the initial state, the flipping rod 18 initially rotates clockwise, acting on the slider 32 through the arc spring 33. Because the rotating sleeve 23 is subject to the rotational resistance of the hexagonal bolt 301, the slider 32 does not initially rotate synchronously with the flipping rod 18. As the arc spring 33 is gradually compressed, its reaction force acts on the slider 32, causing the rotational force of the second gear 29 to overcome the resistance of the hexagonal bolt 301. At this point, the second gear 29 and the flipping rod 18 will rotate synchronously until the hexagonal bolt 301 is fully tightened. The flipping rod 18 can then continue to rotate (the arc spring...). 33 is further compressed), which in turn continuously squeezes the inner steel plate 4 downwards to make the inner steel plate 4 and the steel frame 2 as seamless as possible. After the inner steel plate 4 and the steel frame 2 are welded, the personnel use a wrench to screw the nut from the inside of the U-shaped support frame 3 onto the hexagonal bolt 301. The purpose of this is to reduce the impact on the weld when the personnel twist the nut. If there is a gap between the inner steel plate 4 and the steel frame 2, the preload generated when the personnel twist the nut with a wrench will exert a clamping force on the weld material at the weld, which will destroy the stability of the weld, that is, the weld between the inner steel plate 4 and the steel frame 2 will fail.

[0069] As a further embodiment of the present invention, the entire welding equipment also includes a sliding plate 34, which is slidably connected to the welding square seat 10. Multiple connecting plates 35 are fixedly connected to the side wall of the sliding plate 34. The connecting plates 35 are slidably connected to the welding square seat 10. The ends of the connecting plates 35 are slidably engaged with the rotating screw sleeve 23 (the two slide relative to each other in the horizontal direction, but move synchronously in the vertical direction).

[0070] It also includes a threaded rod 36, which is rotatably connected inside the welding square seat 10. The sliding plate 34 is threadedly connected to the threaded rod 36, and a knob 37 is fixedly connected to the top of the threaded rod 36 after passing through the welding square seat 10.

[0071] After welding is completed, manually turn knob 37 to rotate threaded rod 36. Under the action of threaded connection, sliding plate 34 moves upward, thereby causing multiple rotating sleeves 23 to move upward and disengage from hexagonal bolts 301. Then, servo motor 22 is started, causing the output shaft of servo motor 22 to rotate in the opposite direction, causing flipping rod 18 to drive flipping frame 19 to flip and reset. Compression spring 21 resets, reducing the squeezing effect on welding square seat 10, so that welding square seat 10 can be removed from steel frame 2.

[0072] It should be further explained that during the flipping process of the flipping rod 18, the second gear 29 will be driven to rotate. Through the driving action of the second rack 28, the first rack 27 and the first gear 26, the rotating sleeve 23 will be rotated. Since the rotating sleeve 23 has been separated from the hex bolt 301 in advance, the rotation of the rotating sleeve 23 will not loosen or tighten the hex bolt 301, thus ensuring that the hex bolt 301 is in a tightened state after welding, which helps to reduce the difficulty of installation.

[0073] When the next steel frame 2 needs to be welded, first follow the above operation to move the rotating sleeve 23 downward so that the hex bolt 301 engages with the rotating sleeve 23. This helps to position the welding square seat 10 in the correct position, thereby allowing the welding torch 16 to move along the specified trajectory and ensuring welding quality.

[0074] As a further embodiment of the present invention, the positioning component in this embodiment includes:

[0075] U-shaped base 5, U-shaped base 5 is fixedly connected to the top of machine tool 1;

[0076] Two first positioning plates 7 are symmetrically distributed on both sides of the steel frame 2, and the first positioning plates 7 are slidably connected to the top of the machine tool 1.

[0077] Two first cylinders 6 are symmetrically fixedly connected to both sides of the U-shaped seat 5, and the ends of the telescopic rods of the first cylinders 6 are fixedly connected to the first positioning plate 7.

[0078] The positioning assembly also includes a second positioning plate 9, which is slidably connected to the top of the U-shaped seat 5. A second cylinder 8 is fixedly connected to the top of the U-shaped seat 5, and the bottom end of the telescopic rod of the second cylinder 8 is fixedly connected to the second positioning plate 9.

[0079] Specifically, after the steel frame 2 to be welded is placed on the machine tool 1, the first cylinder 6 and the second cylinder 8 are activated respectively, so that the two first positioning plates 7 move closer to the side wall of the steel frame 2 and position and clamp the side wall of the steel frame 2. The second positioning plate 9 moves downward, generating downward pressure on the top of the steel frame 2. Through the first positioning plate 7 and the second positioning plate 9, the stability of the steel frame 2 is ensured, so that the flipping frame 19 can generate a stable downward force on the welding seat 10 during the flipping process, so that the inner lining steel plate 4 is in full contact with the inner wall of the steel frame 2, thereby improving the welding quality.

[0080] The working principle of this invention is as follows:

[0081] Step 1: Place the steel frame 2 to be welded on the machine tool 1, then start the first cylinder 6 and the second cylinder 8 to drive the second positioning plate 9 and the two first positioning plates 7 to move toward the side wall of the steel frame 2 and position the steel frame 2.

[0082] Step 2: Tighten the hex bolts 301 into the threaded holes of the inner lining steel plate 4. It is best to tighten the four hex bolts 301 to the same depth. Then turn the knob 37 to move the rotating sleeve 23 downward and insert the hex bolts 301 into the rotating sleeve 23. Next, put the welding square seat 10 and the inner lining steel plate 4 into the steel frame 2 together, and at the same time insert the hex bolts 301 into the holes and slots on the steel frame 2.

[0083] Step 3: After the welding square seat 10 is placed inside the steel frame 2, the servo motor 22 is started to drive the two flipping rods 18 to rotate toward each other. The roller 20 at the top of the flipping frame 19 contacts the top of the inner wall of the steel frame 2. The top of the inner wall of the steel frame 2 reacts to the flipping frame 19, causing the flipping frame 19 to move toward the flipping rods 18. The compression spring 21 is compressed to generate elastic force, thereby generating a downward thrust on the welding square seat 10, increasing the contact force between the inner lining steel plate 4 and the inner wall of the steel frame 2.

[0084] Meanwhile, during the flipping process of the flipping rod 18, the drive seat 24 and the rotating screw sleeve 23 are rotated through the transmission of the second rack 28, the second gear 29, the first rack 27 and the first gear 26, so as to realize the automatic tightening of the hexagonal bolt 301. Subsequently, the flipping rod 18 continues to flip, further increasing the contact force between the inner lining steel plate 4 and the inner wall of the steel frame 2, reducing the gap between the inner lining steel plate 4 and the steel frame 2, and ensuring the welding quality.

[0085] Step 4: The welding torch 16 moves along the predetermined trajectory and completes the welding work between the inner lining steel plate 4 and the inner wall of the steel frame 2.

[0086] Step 5: After welding is completed, manually turn the knob 37 to rotate the threaded rod 36. Under the action of the threaded connection, the sliding plate 34 moves upward, thereby causing multiple rotating threaded sleeves 23 to move upward and disengage from the hexagonal bolt 301.

[0087] Step 6: Start the servo motor 22, so that the output shaft of the servo motor 22 rotates, causing the flipping rod 18 to drive the flipping frame 19 to flip and reset, and the compression spring 21 to reset, reducing the squeezing effect on the welding square seat 10, so as to facilitate the removal of the welding square seat 10 from the steel frame 2.

[0088] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
