Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding positioning tooling, and particularly discloses an assembled steel structure assembly welding positioning tooling. BACKGROUND

[0002] A cross beam frame is a very common assembled steel structure assembly. In some large-span factory buildings and commercial and cultural buildings, a cross beam frame with a large span and a large corresponding cross-sectional size is needed. The cross beam frame usually needs to be welded by steel structure assemblies of different lengths. In order to facilitate welding, the steel structure assembly is usually fixed on the surface of a positioner for welding. The positioner can ensure that the welding position is in a flat welding state as much as possible when rotating, thereby ensuring the welding quality. Since the steel structure assembly itself has a large mass and a large span, the middle part of the steel structure assembly may be deformed due to gravity, thereby affecting the welding quality.

[0003] Therefore, a rotating platform for supporting the steel structure assembly is arranged on the existing positioner. The steel structure assembly is placed on the surface of the rotating platform for welding, so as to prevent the steel structure assembly from being deformed and affecting the welding quality. However, since the steel structure assembly itself has a large span, the rotating platform required by the steel structure assembly is also long. Therefore, the self-weight of the rotating platform is increased, which increases the load of the positioner. The rotating platform needs to be fixed for a long time when rotating to different angles during welding, which affects the safety during the welding process. In addition, thermal stress during welding can cause the surface of the steel structure assembly to be deformed, and the middle part of the steel structure assembly and the rotating platform is also deformed, which affects the final welding quality.

[0004] Therefore, there is an urgent need for an assembled steel structure assembly welding positioning tooling which can improve welding safety and ensure welding quality. SUMMARY

[0005] In order to solve the above problems, the present application provides an assembled steel structure assembly welding positioning tooling which can solve the problems mentioned in the background.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be apparently and completely described below with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0028] In order for the personnel in the technical field to better understand the present application, the present application will be further described below with the accompanying drawings and specific embodiments.

[0029] Figure 1 Disclosed is a welded positioning tool for an assembled steel structure assembly. In the embodiment, the assembled steel structure assembly is a large-span steel structure beam. When the large-span steel structure beam is subjected to position welding, the steel structure beam needs to be fixed on the surface of a positioner. The rotating of the positioner changes the rotating angle of the steel structure beam, so that the welding position is in a flat welding state as much as possible, thereby ensuring the welding quality.

[0030] The welded positioning tool for the assembled steel structure assembly includes a base 1 placed on the ground. The base 1 is made of a steel structure material with high strength, has a reinforcing rib plate inside to enhance the rigidity, and has mounting holes or foundation bolt holes (not shown in the figure) at the bottom to ensure the stability of the entire base 1. Since the surface of the base 1 is assembled with a rotating platform 2 for mounting the large-span steel structure beam, the base 1 also needs to have good strength and rigidity, so as to be able to withstand the weight of the steel structure beam without easily deforming.

[0031] The surface of the base 1 is equipped with a driving mechanism 3 for driving the rotation of the rotating platform 2, which enables the rotating platform 2 to rotate to different angles for position welding. The driving mechanism 3 usually includes a driving motor (not shown in the figure), such as a servo motor or a variable frequency motor, which provides precise speed and position control. In order to facilitate the reduction of speed, increase of output torque and realization of self-locking function, the rotating platform 2 stays at a certain angle after rotation, so the driving motor usually needs to be matched with a speed reducer (not shown in the figure) for use. The rotating platform 2 is installed between the base 1 through a rotating bearing (not shown in the figure), which can withstand axial force, radial force and overturning moment.

[0032] As shown in Figure 1 , Figures 4-10 Both sides of the rotating platform 2 are fixedly installed with U-shaped frames 4 through welding or bolt connection. The U-shaped frames 4 also need to be made of high-strength steel structure material. The interiors of the two U-shaped frames 4 are fixedly welded or threadedly installed with circular long shafts 5. The circular long shafts 5 are fixedly connected with connecting rods 6 for improving the supporting force of the circular long shafts 5. The connecting rods 6 are welded at the middle positions of the circular long shafts 5 and the other ends are welded on the surfaces of the U-shaped frames 4, so as to improve the connecting strength of the circular long shafts 5 and the U-shaped frames 4 and ensure the firmness.

[0033] The surfaces of the circular long shafts 5 are slidably installed with sleeve assemblies 7 which can rotate around the circular long shafts 5. The sleeve assemblies 7 are arranged in four, two by two as a group. Two groups are respectively installed on the surfaces of the two circular long shafts 5 and are respectively located at different sides of the connecting rods 6. One group of the sleeve assemblies 7 is used to provide supporting force in the process of rotating the vertical left angle of the rotating platform 2, and the other group of the sleeve assemblies 7 is used to provide supporting force in the process of rotating the vertical right angle of the rotating platform 2.

[0034] The sleeve assemblies 7 include an arc-shaped main plate 71 and two arc-shaped auxiliary plates 72 which can form a circular pipe. The arc-shaped main plate 71 and the arc-shaped auxiliary plates 72 are relatively thick to ensure the overall strength. Electric hinges 73 are installed between the two sides of the arc-shaped main plate 71 and the two arc-shaped auxiliary plates 72. The two arc-shaped auxiliary plates 72 can be rotated and opened through the electric hinges 73 and are sleeved on the surface of the circular long shaft 5. However, it is difficult to ensure the strength of the sleeve assemblies 7 only through the self-locking function of the electric hinges 73. Therefore, connecting assemblies 74 are installed between the arc-shaped main plate 71 and the arc-shaped auxiliary plates 72 for improving the overall strength of the sleeve assemblies 7. A plurality of balls 8 are arranged on the inner walls of the arc-shaped main plate 71 and the arc-shaped auxiliary plates 72. The balls 8 abut against the surface of the circular long shaft 5 to reduce the friction of the sleeve assemblies 7 sliding on the surface of the circular long shaft 5 and facilitate subsequent movement.

[0035] The connecting assembly 74 includes three arc-shaped T-shaped rods 741. The T-shaped rods 741 are also made of steel, and the angle corresponding to their arc is the same as the angle corresponding to the arc of the main arc 71. The main arc 71 and the two arc sub-plates 72 each correspond to one T-shaped rod 741. The ends of the main arc 71 and the arc sub-plates 72 are provided with through T-shaped grooves 742. The T-shaped grooves 742 are also arc-shaped. The T-shaped rods 741 are slidably installed inside the T-shaped grooves 742. A drive assembly 13 for moving the T-shaped rod 741 is installed on the surface of one of the T-shaped rods 741.

[0036] Figure 10 With the connecting assembly 74 in its unconnected state, each T-shaped rod 741 is located inside its corresponding T-shaped slot 742, and the two arc-shaped sub-plates 72 are in a fully open state. Figure 7 For the connecting component 74 to be in the connected state, the driving component 13 needs to drive the corresponding T-shaped rod 741 to move along the inside of the T-shaped groove 742. At this time, two T-shaped rods 741 are inserted into the inside of each T-shaped groove 742 to lock the sleeve component 7. This not only ensures the firmness of the lock, but also reinforces the edge connected by the electric hinge 73, further ensuring the firmness of the sleeve component 7 during use.

[0037] The drive assembly 13 includes an arc-shaped rack 131 fixedly mounted on the side of one of the T-shaped rods 741. A drive gear 132, which drives the arc-shaped rack 131 to rotate, is mounted on the surface of one of the arc-shaped sub-plates 72. The drive gear 132 is mounted on the surface of the arc-shaped sub-plate 72 via a mounting bracket 133. A drive motor (not shown) is mounted on the surface of the mounting bracket 133. The drive motor causes the drive gear 132 to rotate. Through the meshing of the teeth, the drive gear 132 drives the arc-shaped rack 131 to move, thereby moving the corresponding T-shaped rod 741. It should be noted that, to ensure the stability of the T-shaped rod 741 after movement, the T-shaped rod 741 is interference-fitted into the T-shaped groove 742. A self-locking structure can also be installed on the drive motor. When the connecting assembly 74 is in the connected state, the self-locking assembly immediately locks the drive motor. When unlocking is required, the self-locking structure unlocks first. Then, the drive gear 132 drives the arc-shaped rack 131 to rotate, causing the T-shaped rod 741 to fully enter the corresponding T-shaped groove 742. Finally, the two arc-shaped sub-plates 72 are opened by the electric hinge 73. Figure 10 The state shown is sufficient.

[0038] like Figures 2-6As shown, guide rails 9 are slidably mounted on the bottom of the base 1 corresponding to the position of each sleeve assembly 7. The direction of movement of the guide rails 9 is the axial direction of the long axis 5. A sliding groove is opened on the bottom of the inner wall of the base 1, and an electric slider is installed on the bottom of each guide rail 9. The electric slider is located inside the sliding groove. When the sleeve assembly 7 needs to be moved, the electric slider can drive the guide rail 9 to move. When it moves to the appropriate position, the electric slider has a self-locking function to lock the position of the electric slider. A support column 10 for providing support force is fixedly mounted on the surface of the sleeve assembly 7. The support column 10 and the sleeve assembly 7 are integrally molded to ensure a tight connection between them. The end of the support column 10 is rotatably mounted with a movable block 11 that fits against the inner wall of the guide rail frame 9, that is, the support column 10 can rotate around the movable block 11. The guide rail frame 9 is equipped with a positioning component 12 for locking the position of the movable block 11. In this embodiment, the positioning component 12 is a threaded rod 121, which is rotatably mounted inside the guide rail frame 9. A motor (not shown in the figure) is mounted on the surface of the guide rail frame 9 to drive the threaded rod 121 to rotate, thereby controlling the position of the movable block 11.

[0039] Inside the guide rail frame 9, there is a sliding brace 14 for enhancing the support force of the support column 10. The braces 14 in the same set of sleeve assemblies 7 are of different lengths. The top of the brace 14 abuts against the surface of the support column 10, providing strong support for the support column 10. Inside the guide rail frame 9, there is a threaded rod 15 that is rotatably installed. The threaded rod 15 is threaded through the surface of the brace 14. Similarly, a motor (not shown in the figure) is installed on the surface of the guide rail frame 9 to drive the rotation of the threaded rod 15, which can control the position of the brace 14.

[0040] The rotation process of the rotary platform 2 and the corresponding movement process of the moving block 11 and the inclined support column 14 are as follows: Figure 1 For example, when the rotary platform 2 is in a completely horizontal state, one set of longer diagonal braces 14 corresponds to a sleeve assembly 7 that is fitted onto the surface of the long circular shaft 5, and another set of shorter diagonal braces 14 corresponds to a sleeve assembly 7 that is fitted onto the surface of the long circular shaft 5. The remaining sleeve assemblies 7 are as follows: Figure 1 As shown, the long circular shaft 5 is not clamped. At this time, the longer rotating platform 2 can be supported by the cooperation of the two diagonal bracing columns 14 and the support column 10 in the middle, which can avoid the problem of poor welding quality caused by gravity deformation. Since the sleeve assembly 7 can also move, when welding to a specific position, the position of the sleeve assembly 7 can be adjusted to support the area around the welding position, so as to reduce the deformation effect caused by thermal stress.

[0041] by Figure 3For example, when the rotary platform 2 needs to be rotated to change the welding direction, threaded rod 121 and threaded rod 15 rotate simultaneously under the drive of the motor. The corresponding moving block 11 and diagonal support column 14 need to move to ensure that the sleeve assembly 7 is always clamped on the surface of the long cylindrical shaft 5. The shorter diagonal support column 14 needs to be away from the corresponding moving block 11 and abut against the end of the support column 10, while the longer diagonal support column 14 needs to be close to the corresponding moving block 11 and abut against the end of the support column 10. Both can provide stable support force in the tilted state, which can not only ensure welding safety, but also prevent deformation and improve welding quality.

[0042] It should be noted that the movement of the movable block 11 and the diagonal support column 14 is coordinated with the rotation of the long circular shaft 5. This movement path is automatically controlled by a program and belongs to the prior art, so it will not be described in detail in this solution.

[0043] When a flip is required, when rotated to Figure 3 When in this state, the two sleeve assemblies 7 need to open and move away from the long axis 5, and then continue to rotate until they are in contact with the axis. Figure 3 In a symmetrical configuration, the other two sleeve assemblies 7 need to be rotated open and moved to fit onto the surface of the long cylindrical shaft 5, which is... Figure 3 The state of the rotating platform 2 is such that it is easier to weld later. During the flipping process, the diagonal brace 14 and the support column 10 support the rotating platform 2, thereby ensuring the safety of the flipping. Although there are some angles that are difficult to support, they only exist for a very short time. In addition, during this process, the surface of the support column 10 can be simply supported by pressing against the surface of the bottom long circular shaft 5, thereby ensuring the safety of the flipping process.

[0044] It should be noted that although existing positioners have support structures, they can only support the rotary platform 2 in a completely horizontal state. When the steel structure component beams need to be welded in an inclined state, it is difficult to guarantee their stability, especially for large-span steel structure component beams. However, in the present invention, the support column 10, the diagonal brace column 14, and the sleeve assembly 7 can move accordingly with the rotation of the rotary platform 2 to ensure stability in the inclined state. At the same time, for welding at different positions, the position of the sleeve assembly 7 can be adjusted to prevent deformation at the welding position and ensure welding quality. Although the support column 10, diagonal brace column 14, and sleeve assembly 7 are added in this solution, they are all conventional and ordinary mechanical structures. Therefore, the cost of adding the above structures is small. Compared with the prior art, it not only improves the safety of use, but also improves the welding quality. Therefore, it can be used for a long time after one addition, and the cost of adding the above structures is negligible. The above technical solution of the present invention is a specific improvement based entirely on the above-mentioned prior art and to solve the technical problems.
