Description

Technical Field

[0001] This utility model relates to the field of rigid support structure technology, specifically to a rigid support structure for controlling welding deformation. Background Technology

[0002] Rigid support structures for welding deformation control are mainly used to support and constrain the weldment during the welding process, thereby effectively controlling welding deformation and ensuring the dimensional accuracy and quality of the weldment. When the weldment tends to deform, the rigid support structure for welding deformation control can apply a force opposite to the direction of deformation to the weldment, thereby reducing the amount of welding deformation.

[0003] The existing technology has the following problems: Existing devices cannot lock the support position during use. During welding, the weldment will experience complex thermal stress changes due to heat, which may cause the support structure to be subjected to dynamic forces. If the rigid support structure cannot lock the support position, the support components may shift under the action of thermal stress, and in severe cases, they may even completely lose their support function, making it impossible to effectively control welding deformation. In addition, existing devices cannot replace different support heads. Modern industrial weldments have a variety of shapes, from complex curved aero-engine blades to large flat building steel beams. If the rigid support structure cannot replace the support heads, it can only use a single shape of support head. For curved weldments, flat support heads cannot fit properly, resulting in insufficient support and easy loss of control over local deformation. Utility Model Content

[0004] The main purpose of this utility model is to provide a rigid support structure for controlling welding deformation, which can effectively solve the problem.

[0005] To achieve the above objectives, the technical solution adopted in this utility model is as follows: A rigid support structure for controlling welding deformation includes a base.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.

[0017] like Figure 1 As shown, this utility model provides a rigid support structure for controlling welding deformation, including a base 1. Two limiting rods 8 are fixedly connected to the inner surface of the base 1, and two movable seats 4 are slidably connected to the outer wall of the limiting rods 8. A support column 5 is fixedly connected to the upper side of the movable seat 4, and a connecting sleeve 6 is provided at the upper end of the support column 5. A support head 7 is fixedly connected to the upper side of the connecting sleeve 6. Two support plates 2 are fixedly connected to the upper side of the base 1, and multiple slots 3 are provided through the left side of the support plates 2. This rigid support structure for controlling welding deformation is based on the base 1.

The outer wall of the movable block 13 is slidably connected to the movable seat 4, a limiting plate 11 is fixedly connected to the inner surface of the movable seat 4, the outer wall of the limiting plate 11 is slidably connected to the pin 12, and the outer wall of the pin 12 is movably connected to the slot 3. When it is necessary to lock the support position, the knob 9 on the rear side of the movable seat 4 is rotated, and the knob 9 drives the fixed position to be locked. When the first threaded rod 10 of the fixed connection rotates, since the first threaded rod 10 is threadedly connected to the movable block 13 and the outer wall of the movable block 13 is slidably connected to the moving seat 4, the movable block 13 will move forward along the inner wall of the moving seat 4 when the first threaded rod 10 rotates. The two first inclined grooves 14 on the upper side of the movable block 13 will move with the movable block 13, and then push the insertion post 12 fixed at the other end of the connecting rod 15 to move towards the slot 3 through the sliding connection with the connecting rod 15. At the same time, the limiting plate 11 plays a limiting and guiding role for the insertion post 12, ensuring that the insertion post 12 is accurately inserted into the slot 3, thereby fixing the position of the moving seat 4, realizing the locking of the support position, and ensuring that the support structure will not be displaced due to thermal stress and other factors during the welding process.

[0019] like Figure 3-5As shown, this utility model provides a technical solution: Preferably, the lower side of the connecting sleeve 6 has an opening 16, the outer wall of the support column 5 is movably connected to the opening 16, the outer wall of the connecting sleeve 6 has two slots 17, the lower side of the inner surface of the support column 5 is fixedly connected to a motor 18, the output end of the motor 18 is fixedly connected to a second threaded rod 19, the outer wall of the second threaded rod 19 is threadedly connected to a lifting plate 20, the inner surface of the support column 5 is fixedly connected to a fixing plate 23, the outer wall of the fixing plate 23 is slidably connected to two connecting plates 22, the lower side of the connecting plate 22 is fixedly connected to a locking block 21, the outer wall of the locking block 21 is movably connected to the slot 17, the opposite surfaces of the two locking blocks 21 are each provided with a second inclined groove 26, the outer wall of the lifting plate 20 is slidably connected to the second inclined groove 26, the left and right sides of the second inclined groove 26 are each provided with a third inclined groove 24, the left and right sides of the lifting plate 20 are each fixedly connected to two guide posts 25, the guide posts The outer wall of 25 is slidably connected to the third inclined groove 24. When the support head 7 needs to be replaced, the motor 18 fixed on the lower side of the inner surface of the column 5 is started. The motor 18 drives the second threaded rod 19 at the output end to rotate. The second threaded rod 19 is threadedly connected to the lifting plate 20. As the second threaded rod 19 rotates, the lifting plate 20 drives the guide posts 25 on both sides to slide in the third inclined groove 24, which plays a guiding role. The outer wall of the lifting plate 20 is slidably connected to the second inclined groove 26 on the locking block 21. When the lifting plate 20 moves downward, the locking block 21 is pushed inward by the action of the second inclined groove 26. The locking block 21 drives the connecting plate 22 fixed to it to slide along the outer wall of the fixing plate 23, so that the locking block 21 is disengaged from the locking groove 17 on the outer wall of the connecting sleeve 6. At this time, the connecting sleeve 6 and the support head 7 can be removed from the column 5 to complete the disassembly of the support head 7. When installing a new support head 7, the above steps are reversed.

[0020] The working principle of this rigid support structure for welding deformation control will be explained in detail below.

[0021] like Figure 1-5As shown, when the support position needs to be locked, the knob 9 on the rear side of the movable seat 4 is rotated. The knob 9 drives the first threaded rod 10, which is fixedly connected to it, to rotate. Since the first threaded rod 10 is threadedly connected to the movable block 13, and the outer wall of the movable block 13 is slidably connected to the movable seat 4, when the first threaded rod 10 rotates, the movable block 13 will move forward along the inner wall of the movable seat 4. The two first inclined grooves 14 on the upper side of the movable block 13 will move with the movable block 13, and then, through the slidable connection with the connecting rod 15, push the insertion post 12 fixed at the other end of the connecting rod 15 to move towards the slot 3. At the same time, the limiting plate 11 plays a limiting and guiding role for the insertion post 12, ensuring that the insertion post 12 is accurately inserted into the slot 3, thereby fixing the position of the movable seat 4, realizing the locking of the support position, and ensuring that the support structure will not be displaced due to thermal stress or other factors during the welding process. When the support head 7 needs to be replaced, start the motor 18 fixed on the lower side of the inner surface of the support column 5. The motor 18 drives the second threaded rod 19 at the output end to rotate. The second threaded rod 19 is threadedly connected to the lifting plate 20. As the second threaded rod 19 rotates, the lifting plate 20 drives the guide posts 25 on both sides to slide in the third inclined groove 24, which plays a guiding role. The outer wall of the lifting plate 20 is slidably connected to the second inclined groove 26 on the locking block 21. When the lifting plate 20 moves downward, the locking block 21 is pushed inward by the action of the second inclined groove 26. The locking block 21 drives the connecting plate 22 fixed to it to slide along the outer wall of the fixing plate 23, so that the locking block 21 is disengaged from the locking groove 17 on the outer wall of the connecting sleeve 6. At this time, the connecting sleeve 6 and the support head 7 can be removed from the support column 5, and the disassembly of the support head 7 is completed. When installing a new support head 7, the above steps are reversed.
