Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a rotating module for laser processing cylindrical workpieces. Background Technology

[0002] In the field of laser processing technology, the demand for processing cylindrical workpieces is increasing, especially for laser engraving of the entire workpiece, which requires a stable and adjustable support and rotation device. Existing technologies, traditional cylindrical workpiece rotation support devices typically suffer from the following drawbacks: Fixed support spacing: The spacing between the support components in most devices cannot be flexibly adjusted, making it difficult to adapt to the support requirements of cylindrical workpieces of different diameters. When the workpiece diameter changes, the entire support assembly needs to be replaced, which is cumbersome and costly. Inconvenient rotation positioning: Adjusting the position during workpiece rotation is difficult, making it hard to accurately control the engraving position, resulting in insufficient uniformity and precision in laser engraving, affecting processing quality. To address these problems, we propose a rotation module for cylindrical workpieces used in laser processing. Utility Model Content

The system includes a second pulley 9 and a second rubber-coated roller 11 fixed to the other end of the second shaft 10. The first rubber-coated roller 13 and the second rubber-coated roller 11 are arranged in parallel. The cylindrical workpiece is supported by the first rubber-coated roller 13 and the second rubber-coated roller 11. The distance between the first rubber-coated roller 13 and the second rubber-coated roller 11 can be adjusted according to the diameter of the cylindrical workpiece. During adjustment, the bolt assembly is disassembled, and the screws in the bolt assembly are adjusted to be in different positioning holes 15, thereby changing the installation position of the first mounting plate 14. The adjustment is very convenient. The first motor 2 drives the fourth pulley 3 to rotate, the fourth pulley 3 drives the synchronous belt 4 to drive, the synchronous belt 4 drives the first pulley 5 and the second pulley 9 to drive, the first pulley 5 drives the first rubber-coated roller 13 to rotate synchronously through the first rotating shaft 6, and the second pulley 9 drives the second rubber-coated roller 11 to rotate synchronously through the second rotating shaft 10. The first rubber-coated roller 13 and the second rubber-coated roller 11 rotate in the same direction, thereby driving the cylindrical workpiece to rotate, thereby adjusting the position of the cylindrical workpiece, which is convenient for laser engraving on its circumference. A tensioning mechanism for adjusting the tension of the synchronous belt 4 is installed on the rectangular frame 1. The tensioning mechanism is used to adjust the tension of the synchronous belt 4 to ensure the stability of the synchronous belt transmission and to cooperate with the adjustment of the second rubber-coated roller 11 to meet the adjustment requirements. The fourth pulley 3, the first pulley 5, and the second pulley 9 are connected by the synchronous belt 4. The side of the rectangular frame 1 is provided with equidistantly arranged positioning holes 15. The first mounting plate 14 and the second mounting plate 12 are respectively fixedly connected to the rectangular frame 1 by bolt assemblies. The screw in the bolt assembly passes through the positioning hole 15.

[0018] Reference Figure 2The tensioning mechanism includes a translation component, a slider 17, a third rotating shaft 8, and a third pulley 7. A strip-shaped sliding hole is provided on the side of the rectangular frame 1. The slider 17 is slidably installed in the strip-shaped sliding hole. A translation component for driving the slider 17 to translate is installed in the strip-shaped sliding hole. The third rotating shaft 8 is rotatably sleeved on the slider 17.

The distance between the first rubber-coated roller 13 and the second rubber-coated roller 11 is adjusted according to the diameter of the cylindrical workpiece. During adjustment, the bolt assembly is removed, and the screws in the bolt assembly are adjusted to be in different positioning holes 15, thereby changing the installation position of the first mounting plate 14. The adjustment is very convenient. The first motor 2 drives the fourth pulley 3 to rotate, the fourth pulley 3 drives the synchronous belt 4, and the synchronous belt 4 drives the first pulley 5 and the second pulley 9. The first pulley 5 drives the first rubber-coated roller 13 to rotate synchronously through the first rotating shaft 6, and the second pulley 9 drives the second rubber-coated roller 11 to rotate synchronously through the second rotating shaft 10. The rotation direction of the first rubber-coated roller 13 and the second rubber-coated roller 11 is the same, which can drive the cylindrical workpiece to rotate, thereby adjusting the position of the cylindrical workpiece, which is convenient for laser engraving on its entire body. The tensioning mechanism is used to adjust the tension of the synchronous belt 4 to ensure the stability of the synchronous belt transmission and to cooperate with the adjustment of the second rubber-coated roller 11 to meet the adjustment requirements.

[0020] The operating principle of the tensioning mechanism is as follows: the second motor 18 drives the lead screw 16 to rotate, and the lead screw 16 can adjust the position of the slider 17 through the threaded transmission between it and the slider 17. In this way, the synchronous belt 4 is tensioned through the third pulley 7.
