Description

Technical Field

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

[0002] Welding is widely used in traditional manufacturing due to its adaptability to structural geometry, economical material usage, lack of cross-sectional weakening, and ease of fabrication. However, because welding is a localized heating process, welding stress and deformation inevitably occur in structural components during and after welding. In related technologies, to ensure that welding deformation is eliminated after welding, manual hammering is generally used to induce new plastic deformation in the material. In other words, the weld seam and surrounding areas of the structural component are manually hammered to eliminate welding stress and thus straighten the structure.

[0003] However, the above method for straightening structural components is not only inefficient, but also difficult to control due to varying hammering forces from different individuals. This is especially true for structural components with welded skirts, where manual hammering can easily cause unevenness and pitting on the skirt surface, affecting the appearance and quality of the component. Therefore, for straightening structural components with welded skirts, existing patents, such as the Chinese invention patent ZL201611241678.4 (publication number CN106670265A), "A Straightening Fixture for Welding Deformation of Small Cross-Section H-Shaped Steel Flange Plates on a Press," disclose a fixture that is installed on a press. During processing, the fixture is fitted into the H-shaped steel flange plate, and the press is used to compress and straighten the upper and lower flange plates (which are equivalent to the aforementioned "skirt") of the H-shaped steel flange plate from top to bottom. This fixture is only applicable to the flange, also known as the "skirt," that needs to be corrected, where it is perpendicular to the baseline of the structural component. However, if the structural component to be corrected is as follows... Figure 1 The longitudinal beam 1' shown presents another problem. The part of the longitudinal beam 1' to be corrected includes a first skirt 11' and a second skirt 12' welded to the longitudinal beam 1'. The first skirt 11' is perpendicular to the axis Z of the longitudinal beam 1', and the second skirt 12' is parallel to the axis Z of the longitudinal beam 1'.

[0004] Although the aforementioned tooling combined with the press can effectively address the deformation of the first skirt 11' to a certain extent, it still has the following drawbacks: First, since the degree of deformation is entirely controlled by the press, excessive deformation can lead to errors, especially since the deformation of the first skirt 11' varies for different structural components, affecting the correction effect. Second, it cannot simultaneously correct the first skirt 11' and the second skirt 12' located in different dimensions, resulting in low correction efficiency. Third, since the longitudinal beam 1' has a cavity formed by its peripheral wall, and a partition that engages with the peripheral wall is installed within the cavity, forming multiple sub-chambers, the peripheral wall of the longitudinal beam 1' will also deform when the aforementioned press is used for deformation correction.

[0005] Therefore, further adjustments are needed to the structure of the tooling used to control welding deformation. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to provide a tooling for controlling welding deformation that can better adjust the amount of correction deformation of the welding surface, in view of the above-mentioned existing technology.

[0007] The second technical problem to be solved by this utility model is to provide a tooling for controlling welding deformation that can better adjust the deformation of the welding surfaces of the product to be corrected in different dimensions, in light of the above-mentioned existing technology.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a tooling for controlling welding deformation, comprising:

[0009] A workbench for placing a product to be corrected, the product including a body extending along the Z-axis, the bottom periphery of the body having a first skirt extending outward.

[0010] Its features are:

[0011] A support mechanism is provided on the worktable for supporting the lower surface of the first skirt.

[0012] At least two clamping members are provided circumferentially along the first skirt edge, and the head end of each clamping member abuts against the upper surface of the first skirt edge;

[0013] The first shim is correspondingly disposed at the bottom of the tail end of each of the clamping members. By increasing or decreasing the number of the first shims, the position of the clamping member relative to the support mechanism can be adjusted, thereby enabling deformation correction.

[0014] An adjustment mechanism is provided on the worktable for adjusting the flatness of the peripheral wall of the main body. At least two adjustment mechanisms are provided. Each adjustment mechanism includes an adjustment component and a driving mechanism. Under the drive of each driving mechanism, each adjustment component can move to the peripheral wall of the main body to adjust the flatness and at the same time, it can also position and constrain its position.

[0015] To improve the stability of the straightening process, preferably, the support mechanism includes at least two supports and a first support block and a second support block respectively disposed on each of the supports. The second support block is disposed around the first support block, and the product to be straightened is disposed on the first support block. Simultaneously, the tail end of the clamping member is fixed to the second support block. During the straightening process, the clamping member applies a large clamping force to the welding surface. Both the clamping member and the product to be straightened need to remain stable. The first support block, disposed below the welding surface, can disperse the straightening force to ensure the uniformity of the welding surface straightening, and also support the product to be straightened, thereby improving stability. The second support block is used to fix the tail end of the clamping member, thus ensuring the stability of the clamping member.

[0016] To further improve the stability of the clamping component, preferably, the clamping component has an "L" shaped cross-section. The tail end of the clamping component extends for a predetermined length along the X direction perpendicular to the axis Z, while the head end of the clamping component extends for a predetermined length along the Y direction perpendicular to both the axis Z and the X direction. Each tail end of the clamping component and the second support block are provided with a first mounting hole. A first fixing member is provided in the first mounting hole to keep the head end of the clamping component always abutting against the upper surface of the first skirt. The clamping component includes a head end and a tail end that are perpendicular to each other, and its overall cross-section is "L" shaped. On the one hand, the clamping component can provide some avoidance to the product to be corrected, so as to achieve a better clamping effect. On the other hand, the "L" shaped clamping component can meet the correction requirements of the welded surface located at the corner. In addition, the tail end of the clamping component extends along the X direction with a preset length. Its function is to improve the stability of the clamping component installation by reserving an installation position for the first fixing component and increasing the number of the first fixing components as needed. The head end of the clamping component extends along the Y direction with a preset length, so that the head end can better apply clamping force to the welded surface, thereby improving the correction effect.

[0017] For ease of installation, preferably, each of the clamping components has a plane N at both its tail and head ends, while the second support block has a reference plane M parallel to the plane N. The number of the first shims is selectively increased or decreased as needed within the first installation gap formed between the plane N and the reference plane M. By setting the plane N and the reference plane M parallel to each other, the uniformity of the spacing of the first installation gap between them is ensured. Operators can directly adjust the number of first shims according to the actual deformation of the welding surface, thus eliminating the need for flatness calibration while ensuring the corrective effect of the clamping components.

[0018] To address the second technical problem, preferably, the peripheral wall of the main body extends a second skirt from any side wall. The second skirt extends in a Y-direction parallel to the Z-axis. The adjusting component includes a mounting portion connected to the driving mechanism. The mounting portion extends along the Z-axis, and a first arm along the Y-direction is provided for adjusting the flatness of the peripheral wall of the main body. A second arm along the X-direction is provided for adjusting the flatness of the second skirt. This design cleverly integrates the first arm for correcting the deformation of the peripheral wall of the main body and the second arm for correcting the deformation of the second skirt into the mounting portion. This allows for both positioning and constraint of the main body, as well as flatness correction of planes in different dimensions, while also achieving a more compact layout.

[0019] For ease of installation, preferably, the mounting part includes a mounting arm extending along the Z-axis and having a predetermined interval d on the peripheral wall of the main body, an upper extension arm and a lower extension arm extending from the mounting arm in the Y-direction and spaced apart, an upper section having a predetermined distance D between the upper extension arm and the mounting arm, the end faces of the upper extension arm and the lower extension arm being a first plane G that maintains parallel flatness with the peripheral wall of the main body, and an installation space for the first support arm and the second support arm to be installed between the upper section and the mounting arm. The mounting arm maintains a preset distance d from the main body's peripheral wall, providing installation space for the first arm, upper extension arm, and lower extension arm. Furthermore, this application includes an upper section with a preset distance D between the upper extension arm and the mounting arm. This design ensures the overall stability of the product to be corrected. Since the main body of the product to be corrected is relatively tall, the first arm is positioned on the upper section, while the second arm is positioned on the upper extension arm. This allows the arms, distributed at different locations, to make multiple points of contact with the main body's peripheral wall, thus ensuring stability. The end faces of the upper and lower extension arms are set to a first plane G parallel to the main body's peripheral wall, ensuring the corrective effect of the first and second arms.

[0020] To facilitate adjustment of the clamping force, preferably, the first support arm is disposed on the upper section of the mounting arm, and the second support arm is disposed on the upper extension arm. A second mounting gap is formed between the first support arm and the upper section, and between the second support arm and the upper extension arm. A second shim for adjusting the mounting position of the first and second support arms is disposed within the second mounting gap. This second mounting gap design allows for adjustment of the clamping force on the second skirt and the main body perimeter wall. Since the deformation degrees of the main body perimeter wall and the second skirt vary among different products to be corrected, this second mounting gap provides installation space for the second shims. Operators can adjust the number of second shims accordingly based on the deformation degree of the main body perimeter wall and the second skirt, thereby increasing or decreasing the clamping force.

[0021] For ease of fixation, preferably, the first arm, the second arm, and the mounting portion are all provided with second mounting holes, and second fixing members are provided in the second mounting holes for fixing the first arm and the second arm to the mounting portion. The first arm and the second arm correct their deformation by applying pressure to their respective main body perimeter and second skirt edge. To ensure the correction effect, this application uses the second fixing members to fix the first arm to the upper section and the second arm to the upper extension arm, thereby ensuring the stability of the correction.

[0022] To meet the requirements of synchronous correction, preferably, the drive mechanism is a dual-axis drive, which can drive the mounting arm to move the first arm along the Y direction while the second arm translates along the X direction. The dual-axis drive mechanism can independently control movement in two different directions. Since the peripheral wall of the main body to be corrected and the second skirt are located in different dimensions, the drive mechanism can independently control the first arm to translate along the Y direction and the second arm along the X direction, thus meeting the requirement of simultaneous planar correction in different dimensions.

[0023] Compared with the prior art, the advantages of this utility model are as follows: by setting a clamping member on the upper surface of the first skirt of the product to be corrected, and setting an adjustable number of first shims between the clamping member and the first skirt, the position of the clamping member relative to the support structure can be adjusted, thereby controlling the amount of deformation of the first skirt during correction. In addition, an adjustment mechanism is also set on the worktable. This adjustment mechanism can not only adjust the flatness of the main body peripheral wall of the product to be corrected, but also position and constrain the main body, ensuring the stability when correcting the first skirt of the product to be corrected.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 2 to 8 The diagram shows the preferred embodiment of this utility model. The fixture for controlling welding deformation includes a worktable 1 for placing the product A to be straightened. In this embodiment, the product A to be straightened uses a longitudinal beam 1' (see reference). Figure 2The longitudinal beam 1' includes a main body extending along the Z-axis, referred to as A1 in this embodiment. A first skirt extending outward is welded to the bottom periphery of the main body A1, referred to as A2 in this embodiment. A second skirt is provided on the side wall of the peripheral wall of the main body A1, referred to as A3 in this embodiment. The workbench 1 is provided with a support mechanism 2 for supporting the lower surface of the first skirt A2, and four clamping ends 31 are provided on the circumference of the first skirt A2 to abut against the upper surface of the first skirt A2. The clamping component 3 has a first shim 4 at the bottom of its tail end 32. By increasing or decreasing the number of first shims 4, the position of the clamping component 3 relative to the support mechanism 2 can be adjusted, thereby enabling deformation correction. The worktable 1 is also equipped with two adjustment mechanisms 5 for adjusting the flatness of the peripheral wall of the main body A1. Each adjustment mechanism 5 includes an adjustment component 51 and a drive mechanism 52. Under the drive of each drive mechanism 52, each adjustment component 51 can move to the peripheral wall of the main body A1 to adjust the flatness and also to position and constrain its position.

[0035] refer to Figure 3 and Figure 4 The support mechanism 2 includes two supports 21. One support 21 has a first support block 22, and the other support 21 has a second support block 23. The second support block 23 is located around the first support block 22. Since the clamping member 3 applies a large clamping force to the welding surface during the straightening process, both the clamping member 3 and the product A to be straightened need to remain stable. Placing the product A on the first support block 22 can disperse the straightening force, thus ensuring the uniformity of the welding surface straightening, and also provide support for the product A to be straightened, thereby improving stability. Furthermore, the second support block 23 is used to fix the tail end 32 of the clamping member 3, thereby ensuring the stability of the clamping member 3. It should be noted that the clamping member 3 in this embodiment is designed with a special structure with an "L"-shaped cross-section (see reference). Figure 5 The clamping member 3, comprising a head end 31 and a tail end 32 perpendicular to each other, has the following advantages: firstly, it allows the clamping member 3 to provide some clearance to the product A to be corrected, thus achieving a better clamping effect; secondly, the "L"-shaped clamping member 3 can meet the correction requirements of the welded surface located at the corner. Furthermore, the tail end 32 of the clamping member 3 extends along the X direction with a preset length, providing a pre-installed position for the first fixing member 7 and allowing for an increase in the number of first fixing members 7 as needed, thereby improving the stability of the clamping member 3 installation. The head end 31 of the clamping member 3 extends along the Y-square with a preset length, allowing the head end 31 to better apply clamping force to the welded surface, thereby improving the correction effect.

[0036] In actual production, the deformation degree of the welding surface of different products A to be corrected varies. Therefore, operators need to adjust the distance between the clamping part 3 and the support mechanism 2 according to the actual deformation of the welding surface. In this embodiment, the clamping force is adjusted mainly by adjusting the number of first shims 4. To facilitate the installation of the first shims 4, refer to... Figure 6 A first mounting gap 8 is provided between the clamping member 3 and the second support block 23 for the installation of the first shim 4. This first mounting gap 8 is formed by the plane N containing the tail end 32 and head end 31 of the clamping member 3 and the plane M containing the second support block 23. By setting plane N and the reference plane M parallel to each other, the uniformity of the spacing of the first mounting gap 8 between them is ensured. Operators can directly adjust the number of first shims 4 according to the actual deformation of the welding surface, thus eliminating the need for flatness calibration while still ensuring the corrective effect of the clamping member 3. When the deformation of the welding surface of the product A to be corrected is small, operators can reduce the clamping force by adding more first shims 4; when the deformation of the welding surface of the product A to be corrected is large, operators can increase the clamping force by reducing the number of first shims 4.

[0037] In addition, in this embodiment, besides the first skirt A2 requiring flatness correction, the peripheral wall of the main body A1 and the second skirt A3 extending in the Y direction along the side wall of the peripheral wall of the main body A1 also require flatness correction. Since the peripheral wall of the main body A1 and the second skirt A3 are in different dimensions from the first skirt A2, in order to achieve flatness correction in different dimensions, reference is made to... Figure 7 and Figure 8In this embodiment, the adjusting member 51 includes a mounting part 511 connected to the driving mechanism 52. The mounting part 511 extends along the Z-axis. The mounting part 511 integrates a first arm 512 for correcting the deformation of the peripheral wall of the main body A1 and a second arm 513 for correcting the deformation of the second skirt A3. The first arm 512 and the second arm 513 can not only position and constrain the main body A1, but also correct the flatness of planes located in different dimensions, and can also be more compact in terms of layout space. Meanwhile, the mounting part 511 includes a mounting arm 5111 extending along the axis Z and having a preset interval d on the periphery of the main body A1, an upper extension arm 5112 and a lower extension arm 5113 extending from the mounting arm 5111 in the Y direction and spaced apart. The preset interval d provides mounting space 13 for the first arm 512, the upper extension arm 5112 and the lower extension arm 5113. At the same time, since the main body A1 of the product A to be corrected is relatively tall, the first arm 512 is set on the upper section 5114 and the second arm 513 is set on the upper extension arm 5112, so that the arms distributed at different positions can make multiple contacts with the periphery of the main body A1 to ensure its stability. The end faces of the upper extension arm 5112 and the lower extension arm 5113 are set as a first plane G parallel to the periphery of the main body A1, which can ensure the corrective effect of the first arm 512 and the second arm 513.

[0038] Furthermore, the deformation degrees of the peripheral wall of the main body A1 and the second skirt A3 of different products A to be corrected vary. In order to facilitate the adjustment of the clamping force applied to the first support arm 512 and the second support arm 513, this embodiment provides a second mounting gap 12 for mounting the second gasket 9 between the first support arm 512 and the upper section 5114, and between the second support arm 513 and the upper extension arm 5112 (see reference). Figure 8 It should be noted that the second shim 9 is the same as the first shim 4 mentioned above. The operator can adjust the number of the second shims 9 according to the degree of deformation of the main body A1 perimeter wall and the second skirt A3. When the deformation of the main body A1 perimeter wall and the second skirt A3 is small, the number of the second shims 9 needs to be increased; when the deformation of the main body A1 perimeter wall and the second skirt A3 is large, the number of the second shims 9 can be reduced accordingly. The first support arm 512, the second support arm 513 and the mounting part 511 are all provided with second mounting holes 10. The second mounting holes 10 are provided with second fixing members 11 for fixing the first support arm 512 and the second support arm 513 to the mounting part 511. It should be noted that the second mounting holes 10 are the same as the first mounting holes 6 mentioned above, and the second fixing members 11 are the same as the first fixing members 7 mentioned above. In this embodiment, the first fixing members 7 and the second fixing members 11 are preferably bolts that are easy to install.

[0039] Finally, the drive mechanism 52 used in this embodiment is preferably a dual-axis drive. The drive mechanism 52 can independently control the movement in two different directions. Since the peripheral wall of the main body A1 to be corrected and the second skirt A3 are located in different dimensions, the drive mechanism 52 can independently control the first arm 512 to translate along the Y direction and the second arm 513 to translate along the X direction, thus meeting the requirement of synchronous plane correction in different dimensions.

[0040] The following uses a longitudinal beam applied in the automotive field as an example to illustrate the working principle of the tooling used to control welding deformation: The longitudinal beam is placed on the first support block 22, and the deformation of the welding surfaces of the first skirt A2 and the second skirt A3 on the longitudinal beam is observed. The operator calculates the amount of welding deformation based on welding theory and uses this as the basis for correcting the welding deformation. At the same time, appropriate adjustments are made based on actual production experience on site. An appropriate number of first shims 4 are set in the first installation gap 8, and the first fixing member 7 is tightened to fix the clamping member 3 on the second support block 23. Similarly, an appropriate number of first shims 4 are set in the second installation gap 12. The second shim 9 is tightened and the second fixing member 11 is tightened to fix the first arm 512 and the second arm 513 to the mounting part 511. The clamping member 3 applies a downward clamping force along the axis Z to the first skirt A2 to correct the flatness of the first skirt A2. At the same time, the driving mechanism 52 drives the first arm 512 to move along the Y direction and apply a clamping force to the peripheral wall of the main body A1 to correct it. Meanwhile, the second arm 513 moves along the X direction and applies a clamping force to the second skirt A3 to correct it. After the correction is completed, the clamping member 3, the first arm 512 and the second arm 513 are reset, and the correction is completed.
