Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a linear welding positioning device. Background Technology

[0002] Welding technology, also known as joining engineering, is an important material processing technology. Welding is a process in which the materials of the workpieces are permanently joined by heating or pressurizing, or both, with or without filler material, to achieve atomic bonding between the materials.

[0003] Existing linear welding equipment often involves placing the object to be welded directly on the base, with the operator holding the welding device to weld it. However, this method does not limit the object's movement, making it prone to shifting during the welding process and causing welding deviations. Utility Model Content

[0004] The purpose of this utility model is to provide a linear welding positioning device to solve the problem that the welding of objects is prone to deviation when the personnel use handheld welding equipment.

[0005] To achieve the above objectives, this utility model provides a linear welding positioning device, which includes:

[0006] The positioning columns are arranged in a straight line.

[0007] A drive assembly is disposed at the bottom of the positioning column;

[0008] The limiting component includes a cotter pin and an expansion joint inner support pin, one end of the cotter pin being inserted into the end of the positioning column away from the driving component, and the expansion joint inner support pin being inserted into the other end of the cotter pin.

[0009] As a further description of the above technical solution:

[0010] The cotter pin has several slits at its upper end, and these slits are arranged circumferentially along the cotter pin.

[0011] As a further description of the above technical solution:

[0012] A threaded tie rod is connected to the inner support pin of the expansion joint.

[0013] As a further description of the above technical solution:

[0014] The positioning column is provided with a limit block, which is detachably connected to the positioning column by bolts.

[0015] As a further description of the above technical solution:

[0016] The drive assembly includes a base, a lower fixing plate, an upper fixing plate, and a cylinder. The lower fixing plate is connected to the base, the cylinder is mounted on the lower fixing plate, the upper fixing plate is connected to the piston rod of the cylinder, and the positioning column is connected to the upper fixing plate.

[0017] As a further description of the above technical solution:

[0018] The lower fixing plate is provided with guide posts at its four corners, and the upper fixing plate is provided with guide holes, with the guide posts movably connected in the guide holes.

[0019] As a further description of the above technical solution:

[0020] The positioning column is equipped with a limit pin.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: The positioning column allows the product to be welded to be fitted onto it, and the expansion joint inner support pin is inserted into the cotter pin, causing the top of the cotter pin to expand and deform outwards, thereby holding the product in place and achieving the purpose of fixing it. The operation is simple and convenient. The cylinder allows the positioning column to move up and down, achieving position adjustment and further improving welding quality. After welding, the expansion joint inner support pin is removed, making it easy to remove the product from the positioning column, thus improving efficiency. Attached Figure Description

[0032] Please see Figure 1-2 This utility model provides a linear welding positioning device, comprising:

[0033] Positioning column 1, which is arranged in a straight line;

[0034] A drive assembly is disposed at the bottom of the positioning column 1;

[0035] The limiting component 2 includes a cotter pin 21 and an expansion joint inner support pin 22. One end of the cotter pin 21 is inserted into the end of the positioning column 1 away from the driving component, and the expansion joint inner support pin 22 is inserted into the other end of the cotter pin 21.

[0036] The cotter pin 21 has a plurality of slits 3 at its upper end, which are arranged circumferentially along the cotter pin 21. The slits extend along the axis of the cotter pin, and the length of the slits is 1 / 2 to 2 / 3 of the length of the cotter pin, which facilitates the deformation of the cotter pin.

[0037] A threaded rod 11 is connected to the inner support pin 22 of the expansion opening. This facilitates the removal and placement of the inner support pin of the expansion opening.

[0038] The positioning column 1 is provided with a limiting block 4, which is detachably connected to the positioning column 1 by bolts. This serves to limit the position of the product, making the product more accurately fixed.

[0039] The drive assembly includes a base 5, a lower fixing plate 6, an upper fixing plate 7, and a cylinder 8. The lower fixing plate 6 is connected to the base 5, the cylinder 8 is mounted on the lower fixing plate 6, the upper fixing plate 7 is connected to the piston rod of the cylinder 8, and the positioning column 1 is connected to the upper fixing plate 7.

[0040] The lower fixed plate 6 has guide posts 9 at its four corners, and the upper fixed plate 7 has guide holes 12. The guide posts 9 are movably connected within the guide holes 12. This allows the upper fixed plate to move more stably and prevents it from shifting.

[0041] The positioning column 1 is equipped with a limit pin 10, which serves the purpose of positioning.

[0042] Working principle: During use, the product to be welded is placed on the positioning column, and then the expansion joint inner support pin is inserted into the cotter pin, causing the top of the cotter pin to expand and deform outward, thereby holding the product in place and achieving the purpose of fixing the product. The operation is simple and convenient. Through the set cylinder, the positioning column can be moved up and down to adjust the position, which can further improve the welding quality. After welding is completed, the expansion joint inner support pin is pulled out, which makes it easy to remove the product from the positioning column, thus improving efficiency.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
