At the same time, some toolings are also equipped with fine-tuning mechanisms for more precise position adjustment. These improvements have significantly improved the quality of column riveting and welding.

[0005] However, despite certain progress in the existing technologies, there are still some technical problems to be urgently solved in practical applications: (1) Although the existing multiple fixing toolings can achieve preliminary alignment, they still have deficiencies in ensuring the parallelism and alignment of the end face heights of two columns, and it is difficult to meet the requirements of high-precision welding; (2) The adjustment mechanisms of many existing toolings are complex in design and cumbersome in operation, increasing the labor intensity of workers and the adjustment time, and reducing the production efficiency; (3) During the welding process, due to the influence of thermal stress and mechanical stress, the columns may produce small displacements or deformations, and the existing toolings are difficult to effectively prevent this situation from occurring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further illustrates the present utility model in conjunction with the drawings and embodiments, but these specific implementation schemes do not limit the protection scope of the present utility model in any way. Embodiment

[0030] As Figures 1-3 shown, a riveting and welding column positioning tooling includes two column positioning toolings 1, a track platform 2 provided between the two column positioning toolings 1, and an adjustment platform 3 installed on the track platform 2.

[0031] In this embodiment, each column positioning tooling 1 is composed of a right-angled triangular column platform 4 and a convex-shaped positioning plate 5 arranged on one side of the column platform 4 (inside the right-angled vertical surface). The central position of the positioning plate 5 is a disc-shaped structure, and two circumferential positioning areas 6 are provided on the circumference of this disc-shaped structure. A plurality of positioning holes 7 are provided on each circumferential positioning area 6, and these positioning holes 7 are used to fix the extended surface of the column 9.

[0032] In this embodiment, a positioning area 6 that gradually depresses from the outer circle to the inner circle is provided at the center of the column positioning tooling 1. This sunken positioning area 6 forms an inwardly sunken cylindrical structure, which can guide the column 9 to be accurately positioned at the center position of the tooling, further improving the positioning accuracy.

[0033] In this embodiment, a locking mechanism 16 is also provided on the column positioning tooling 1. The locking mechanism 16 is a plurality of positioning rods 8. The positioning rods 8 are inserted into the positioning holes 7 to firmly fix the column 9 after positioning, or directly pass through the through holes distributed on the extended surface of the column 9, pass through the through holes and insert into the positioning holes 7 to position the column 9 at an appropriate position in the positioning area 6, and can also be adjusted according to the size and shape of the column 9.

[0034] In this embodiment, the track platform 2 is a rectangular structure and is made of high-strength materials. A precision track 10 is machined on the upper surface of the track platform 2, and the design of the track 10 ensures that the adjustment platform 3 can move smoothly on it.

[0035] In this embodiment, the adjustment platform 3 includes a horizontal sliding platform 11 installed on the track 10 and a vertical lifting platform 12 arranged on the horizontal sliding platform 11; and a horizontal adjustment mechanism arranged on the horizontal sliding platform 11 for adjusting the position of the adjustment platform 3 in the horizontal direction; a vertical adjustment mechanism arranged on the top of the horizontal sliding platform 11 for adjusting the position of the adjustment platform 3 in the vertical direction.

[0036] The above-mentioned horizontal adjustment mechanism is a handle 13 provided on each side of the adjustment platform 3. The operator can easily realize the left and right movement of the adjustment platform 3 on the track 10 by manually pushing and pulling these handles 13.

[0037] The above-mentioned vertical adjustment mechanism adopts a structure similar to a pneumatic cylinder or a hydraulic cylinder, including a sealed cylinder 14 and a piston rod 15 cooperating with it. By controlling the air pressure or hydraulic pressure, the piston rod 15 can move up and down smoothly, thereby realizing the vertical adjustment of the adjustment platform 3.

[0038] In this embodiment, a locking mechanism 16 is also provided on the adjustment platform 3, including a number of quick locking devices. For example, a wedge block controlled by an operating rod is provided at the bottom of the adjustment platform 3. The wedge block is made to abut against the track 10 through the operating rod to fix the adjustment platform 3 and prevent it from moving during the welding process.

[0039] The working principle of this riveting and welding column positioning tooling is as follows:

[0040] First step: The operator first checks whether the two column positioning toolings 1, the track platform 2 and the adjustment platform 3 are correctly installed in place. Ensure that all components are functioning properly, including the convex-shaped positioning plate 5 of the column positioning tooling 1, the precision track 10 of the track platform 2, the horizontal and vertical adjustment mechanisms of the adjustment platform 3, etc.

[0041] Second step: The operator places the first column 9 on the adjustment platform 3. By operating the handles 13 on both sides of the adjustment platform 3, adjust the position of the column 9 in the horizontal direction so that it is roughly aligned with the column positioning tooling 1 on one side.

[0042] Third step: The operator uses the vertical adjustment mechanism (pneumatic cylinder or hydraulic cylinder structure) of the adjustment platform 3 to adjust the height of the column 9 so that it is precisely aligned with the disc-shaped structure at the center of the convex-shaped positioning plate 5 of the column positioning tooling 1, ensuring that the extension surface of the column 9 corresponds to the positioning holes 7 on the positioning plate 5.

[0043] Fourth step: When the position of the first column 9 is correct, the operator uses the positioning rod 8 on the column positioning tooling 1 to pass through the extension surface and the positioning hole 7 of the column 9 to lock the column 9, and adjusts the position of the positioning rod 8 according to the size and shape of the column 9 to ensure firm fixation.

[0044] Fifth step: The operator places the second column 9 on the adjustment platform 3. Repeat the operations of the second and third steps to adjust the position of the second column 9 so that it is aligned with the column positioning tooling 1 on the other side.

[0045] Sixth step: The operator finely adjusts the horizontal and vertical positions of the adjustment platform 3 to ensure that the two columns 9 are completely aligned. At the same time, carefully check the weld position between the two columns 9 to ensure that the welds are perfectly centered.

[0046] Seventh step: Once it is confirmed that the positions of the columns 9 and the centering of the welds meet the requirements, the operator uses the locking mechanism 16 (such as a wedge block) at the bottom of the adjustment platform 3 to lock the position of the adjustment platform 3 to prevent it from moving during the subsequent welding process.

[0047] Eighth step: The operator comprehensively checks the positions, alignment and locking status of the two columns 9 again to ensure that everything is ready. If any adjustment is needed, the adjustment platform 3 can be unlocked and returned to the sixth step for fine-tuning.

[0048] Ninth step: After completing all adjustments and inspections, the operator can start the welding work. After welding is completed, unlock the adjustment platform 3 and the column positioning tooling 1, remove the column 9, and complete the entire riveting and welding column alignment process.

[0049] The beneficial effects that a riveting and welding column positioning tooling of the above embodiments can produce include the following points:

[0050] 1. By setting two column positioning devices, each device including a base and a positioning plate, and a plurality of positioning structures are provided on the positioning plate, combined with the use of an adjustment platform, a high-precision column positioning and adjustment system is formed. Compared with the traditional simple fixing or single alignment method, the present invention effectively solves the problem that it is difficult to ensure the parallelism and alignment of the end face heights of two columns, and significantly improves the welding precision and stability. It enables the column to obtain multi-point support and precise adjustment during the positioning process, ensuring the requirements of high-precision welding, and greatly improving the welding quality and efficiency.

[0051] 2. By setting a connection mechanism between the two column positioning devices and installing a movable adjustment platform on the connection mechanism, a flexible and adjustable column position adjustment system is formed. Compared with the complex and cumbersome adjustment mechanisms in the existing tooling, it effectively solves the problems of long adjustment time and complex operation in the adjustment process, greatly simplifies the operation process, and improves the production efficiency. At the same time, it improves the adaptability of the tooling and can adapt to the welding requirements of columns with different specifications and sizes.
