Description

Technical Field

[0001] The utility model belongs to the technical field of laser cleaning fixture structures, in particular to a laser cleaning and clamping device for a cylindrical workpiece. Background Art

[0002] During laser welding, contaminants such as oil often form on the weld seam of the workpiece. These contaminants, when exposed to high temperatures, can generate gases or affect the normal flow of the molten pool, leading to weld quality issues. Previous processes used solvent oil to clean the workpiece. While this method effectively removes oil and the solvent oil evaporates quickly, leaving minimal residual oil on the workpiece surface and ensuring good laser welding quality, it is now replaced by laser cleaning due to its flammability and explosiveness, as well as its significant environmental pollution.

[0003] During the laser welding process, oil stains form on the adjacent end faces and side surfaces of connected cylindrical workpieces. The existing laser cleaning process for these ends and adjacent side surfaces involves positioning the workpiece end-facing upward, driving the workpiece in translation with a power unit, and cleaning the end surface with the laser head. The workpiece is then laid flat, rotated by a power unit, and cleaned from the side surfaces with the laser head.

[0004] In the above cleaning steps, the operator needs to clamp the cylindrical workpiece twice, and the power device needs to drive the cylindrical workpiece to move in two directions, which is not only time-consuming and labor-intensive, but also multiple clampings are more likely to cause damage to the cylindrical workpiece.

[0027] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0028] See also Figure 1 The utility model provides a cylindrical workpiece laser cleaning and clamping device, including a positioning assembly and a power unit 2, a cylindrical workpiece 3 is mounted on the positioning assembly, the power unit 2 drives the cylindrical workpiece 3 to move, and the laser head cleans the welding end face and welding side face of the cylindrical workpiece 3, the positioning assembly includes an angle adjustment part 11 and a clamping part 12, the cylindrical workpiece 3 is mounted on the clamping part 12, the angle adjustment part 11 adjusts the angle between the central axis of the cylindrical workpiece 3 and the horizontal plane; the power unit 2 drives the cylindrical workpiece 3 to rotate, and the laser head faces the horizontal plane.

[0029] like Figure 1 、 Figure 3 and Figure 4As shown, when the device is working, the angle adjustment part 11 adjusts the cylindrical workpiece 3 to a certain inclination angle according to the area of ​​oil stains to be cleaned on the end face and side face of the cylindrical workpiece 3, that is, the central axis of the cylindrical workpiece 3 and the horizontal plane form a certain angle, and then the power part 2 drives the cylindrical workpiece 3 to rotate, and the laser head starts cleaning. Because the cylindrical workpiece 3 is tilted at a certain angle, the laser head can clean the end face of the cylindrical workpiece 3 and the side part adjacent to the end face at the same time, so there is no need to clamp the end face and side face of the cylindrical workpiece 3 twice as in the existing process technology, and solves the problem that the laser is used to clean the oil stains on the end face and the side face adjacent to the end face in the existing technology, which requires two clampings, which is not only time-consuming and labor-intensive, but also multiple clampings are more likely to cause damage to the cylindrical workpiece 3.

[0030] In another embodiment, see Figure 2 The angle adjustment portion 11 includes a fixed plate 111, an angle adjuster 112 and an adjustment plate 113 installed above the fixed plate 111; one end of the adjustment plate 113 is hinged to one end of the fixed plate 111, and the angle adjuster 112 drives the adjustment plate 113 to rotate; the clamping portion 12 is fixedly mounted on the adjustment plate 113, and the cylindrical workpiece 3 is rotatably mounted on the clamping portion 12, and the rotation of the adjustment plate 113 drives the change of the angle between the central axis of the cylindrical workpiece 3 and the horizontal plane. Compared with the angle adjustment portion 11 with an integral design, the laser cleaning device for cylindrical workpiece 3 can adjust the inclination angle of the cylindrical workpiece 3 in time according to the area of ​​oil stains to be cleaned on the end face and side face of the cylindrical workpiece 3 through the design of the angle adjustment portion 11 composed of the fixed plate 111, the angle adjuster 112 and the adjustment plate 113, that is, adjust the angle between the central axis of the cylindrical workpiece 3 and the horizontal plane, and the applicability of this device is better.

Compared to using hydraulic rods or other telescopic rods to adjust the angle, the lead screw 1122 structure allows for more precise adjustment.

[0032] In another embodiment, see Figure 2The power unit 2 is fixedly mounted on the adjustment plate 113. The power unit 2 includes an output shaft 21, which rotates when the power unit 2 is in operation. The clamping unit 12 includes a clamping cylinder 121 and a connecting column 122, the clamping cylinder 121 is fixedly connected to the power unit 2, and the connecting column 122 is fixedly connected to the output shaft 21.

[0033] In another embodiment, see Figure 2 The cylindrical workpiece 3 is a hollow structure, and the outer wall of the connecting column 122 and the center hole of the cylindrical workpiece 3 are interference fit. When the output shaft 21 of the power unit 2 rotates, the connecting column 122 is driven to rotate, and the connecting column 122 drives the cylindrical workpiece 3 to rotate, so that the laser head can clean the entire end of the cylindrical workpiece 3 and the side adjacent to the end.

[0034] In another embodiment, see Figure 2 The cylindrical workpiece 3 is a solid structure, and a connecting hole is provided at the top of the connecting column 122. The outer wall of the cylindrical workpiece 3 and the connecting hole are interference fit. Here and in the previous embodiment, the design requirements of the connecting column 122 when processing different types of cylindrical workpieces 3 are listed respectively.

During operation, the angle adjustment part 11 adjusts the cylindrical workpiece 3 to a certain inclination angle according to the area of ​​oil stains to be cleaned on the end face and side face of the cylindrical workpiece 3, that is, the central axis of the cylindrical workpiece 3 and the horizontal plane form a certain angle, and then the power part 2 drives the cylindrical workpiece 3 to rotate, and the laser head starts cleaning. Because the cylindrical workpiece 3 is tilted at a certain angle, the laser head can simultaneously clean the end face of the cylindrical workpiece 3 and the side part adjacent to the end face, so there is no need to clamp twice like the existing process technology to clean the end face and side face of the cylindrical workpiece 3 respectively, which solves the problem that the existing technology uses laser to clean the oil stains on the end face and the side face adjacent to the end face, which requires two clampings, which is not only time-consuming and labor-intensive, but also multiple clampings are more likely to cause damage to the cylindrical workpiece 3.
