Description

Technical Field

[0001] The invention relates to the technical field of metal pipe cutting, and more particularly to a laser cutting device used for processing metal pipes of sports equipment. Background Art

[0002] In the prior art, cutting equipment plays a vital role in the processing of metal pipes for sports equipment. These devices are usually used to accurately cut metal pipes to meet the design requirements of different sports equipment. However, current cutting equipment often has some limitations when facing complex cutting tasks, especially when cutting at different angles is required. Operators usually need to adjust the position of the laser to adapt to the requirements of various cutting angles. This adjustment process is not only time-consuming, but may also affect the cutting accuracy and efficiency.

[0003] When adjusting the angle of existing cutting equipment, the common practice is to rotate the laser itself. However, this method has a significant flaw: when the laser rotates, its cutting point often deviates from the original positioning point. This deviation not only leads to a decrease in cutting accuracy, but may also cause material waste. What is more serious is that this error may accumulate and affect the quality control of the entire processing process. Summary of the invention

[0037] Working principle: When it is necessary to cut the metal pipe fittings of sports equipment, first install the pipe body 46 between the fitting wheel 45 and the driving wheel 37, and then the rotation speed of the pipe body 46 can be accurately controlled by the servo motor 38, and then the pipe body 46 is cut by the laser 5. Since the rotation speed of the pipe body 46 can be accurately controlled by the servo motor 38, the corresponding cutting can be carried out in cooperation with the laser 5. When it is necessary to adjust the position between the laser 5 and the rotating plate 2, since the transverse block 4 is slidably connected in the slide groove 13, the transverse block 4 can be driven to adjust to the corresponding position along the slide groove 13 and the transverse bolt 22 is rotated so that the transverse bolt 22 contacts the slide groove 13, thereby completing the fixation of the transverse block 4. Therefore, the laser 5 is also in a fixed state at this position, and then the cutting process of the pipe body 46 is completed. When it is necessary to cut the pipe body 46 at different angles, first Different friction holes 31 are selected according to corresponding situations, and then the insertion rod 7 is passed through the corresponding rotation hole 14 and rotatably connected in the corresponding rotation sleeve 6. At this time, the rotating plate 2 can rotate along the position of the corresponding rotation sleeve 6. The position of the rotation sleeve 6 selected at this time is the position closest to the tube body 46, so it can adapt to the corresponding diameter of the tube body 46. At this time, when the rotating plate 2 rotates along the corresponding rotation sleeve 6, since the diameters of the rotating sleeve 6 and the tube body 46 match, the laser 5 will be tightly attached to the side wall of the tube body 46 when adjusting the corresponding angle, thereby avoiding the situation where it will be away from the corresponding cutting point position when rotating. Therefore, the cutting accuracy can be improved, and the accuracy of cutting at the corresponding position and angle is guaranteed. If the rotating sleeve 6 rotates along the position of the axis of the tube body 46, the laser 5 will be rotated to a position away from the corresponding cutting point, thereby deviating from the cutting position and reducing the overall cutting accuracy.

[0038] When it is necessary to fix the insertion rod 7 and the rotating sleeve 6, first install the intermediate sleeve 8 in the corresponding friction hole 31, and then respectively connect the two clamping sleeves 9 in the friction hole 31 in the opposite direction, and the hexagonal sleeve 23 can be rotated. Then, the intermediate sleeve 8 can be fixed in the corresponding friction hole 31 through the two clamping sleeves 9, and then the insertion rod 7 is inserted into the intermediate sleeve 8. At this time, the insertion rod 7 will push the clamping rod 12 open, so that the multiple clamping rods 12 expand outward, and then continue to move downward. At this time, the return spring 16 is in compression. state, and then continue to move downward so that the clamping rod 12 is clamped in the annular groove 17. At this time, the stop rod 24 is clamped on the upper end surface of the telescopic rod 11. Therefore, multiple clamping rods 12 can be respectively clamped on the annular groove 17. At this time, the insertion rod 7 is inserted into the rotating sleeve 6, thereby completing the fixing process. When it needs to be unlocked, it is only necessary to drive the handle 25 to pull upward with force. There is a rounded corner 18 on the insertion rod 7, which can continue to expand outward through the rounded corner 18, thereby unlocking the clamping connection with the annular groove 17, and then the next adjustment can be made.

[0039] In order to fix the angle of the rotating plate 2, a clamping mechanism is added. Figure 1-2 The clamping mechanism includes a lower pressure rod 26, a holding rod 27, a rotating block 28, a lower pressure spring 29 and a friction plate 30. A friction hole 31 is opened on the rotating plate 2, and the friction hole 31 passes through the friction block 3. The lower pressure rod 26 is threadedly connected to the friction hole 31, one end of the lower pressure spring 29 is connected to the lower pressure rod 26, and the other end of the lower pressure spring 29 is connected to the friction plate 30. The friction plate 30 is attached to the bottom plate 1, the rotating block 28 is installed on the lower pressure rod 26, and the rotating block 28 is attached to the slide groove 13, and the holding rod 27 is coaxially installed on the lower pressure rod 26.

[0040] Working principle: After the rotation connection between the insertion rod 7 and the rotating sleeve 6 is completed, the rotating plate 2 can be rotated along the rotating sleeve 6 by rotating it. At this time, the top plate 21 is in contact with the lower end surface of the top plate 20, and the two friction blocks 3 are respectively attached to the bottom plate 1. Then, when it is adjusted to the corresponding angle and needs to be fixed, since the lower pressure rod 26 is threadedly connected in the friction hole 31, a corresponding thrust can be applied to squeeze the lower pressure spring 29, and then the friction plate 30 passes through the friction block 3 and rubs against the bottom plate 1. At this time, the fixation of the rotating plate 2 is guaranteed by the friction force provided between the friction plate 30 and the bottom plate 1, so that the rotating plate 2 can be fixed at the corresponding angle, and then the angle fixation of the laser 5 is completed, and then the servo motor 38 drives the rotation of the tube body 46, thereby completing the cutting of the tube body 46 at the corresponding angle.

[0041] See also Figure 7-10In order to realize the convenient fixation of different pipe fittings, a fixing mechanism is added, which includes a guide sleeve 32, a guide rod 33, a hydraulic cylinder 34 and a lifting plate 35.

A tube body 46 is fitted between the drive wheel 37 and the receiving wheel 40, a plurality of fixing plates 47 are equidistantly provided on the fitting spring 42, and a fixing bolt 48 is threadedly provided on each fixing plate 47, a plurality of vertical holes 49 are respectively provided on the fitting frame 43 and the fixing frame 41, and a through hole 50 is respectively provided on each fixing plate 47, and the vertical hole 49 and the through hole 50 are coaxially arranged, a deformation ring 51 is provided on the fitting frame 43, and a plurality of top springs 52 are equidistantly provided on the inner wall of the deformation ring 51, and a top sleeve 53 is provided on the plurality of top springs 52 A threaded rod 54 is provided on the inner thread of the top sleeve 53, an adjusting rod 55 is provided on the threaded rod 54, a fixing ring 56 is provided on the fixing frame 41, a plurality of bottom springs 57 are equidistantly provided on the inner wall of the fixing ring 56, a bottom sleeve 58 is provided on the plurality of bottom springs 57, a pull rope 59 is fixedly and slidably provided on the bottom sleeve 58, and a limiting plate 60 is provided on the lower end surface of the pull rope 59, the limiting plate 60 is attached to the bottom sleeve 58, the pull rope 59 is connected to the threaded rod 54, and an expansion rod 61 is provided on each two fitting frames 43, and the expansion rod 61 and the lifting plate 35 are arranged in parallel.

[0042] Working principle: When the tube body 46 needs to be installed between the bottom wheel 44 and the fitting wheel 45, the fitting spring 42 can be bent by pulling the two expansion rods 61, and then the tube body 46 is placed on the bottom wheel 44 and the expansion rods 61 are released. At this time, under the action of the fitting spring 42, the fitting wheel 45 can be abutted against the tube body 46, so that there is a corresponding friction between the tube body 46 and the driving wheel 37, thereby ensuring the continuity of rotation. When the initial bending position of the fitting spring 42 needs to be adjusted, the adjustment spring 42 is first turned. The section rod 55, since the threaded rod 54 on the adjustment rod 55 and the top sleeve 53 are threadedly connected, and the limit plate 60 on the pull rope 59 and the bottom sleeve 58 are fitted together, the position between the threaded rod 54 and the top sleeve 53 can be changed, and the position between the fixed ring 56 and the deformation ring 51 can be adjusted under the action of the pull rope 59. Since the deformation of the fitting spring 42 can be changed under the tension of the pull rope 59, the initial position of the fitting wheel 45 can be changed, thereby improving the convenience of placing the tube body 46 on the bottom wheel 44.

[0043] When it is necessary to change the fixing force between the fitting wheel 45 and the tube body 46 according to different situations, first select the fixing bolts 48 of corresponding length and install them on multiple fixing plates 47. Since the fixing plates 47 are in the connected state and the fitting springs 42 are in a fixed state, only the fitting springs 42 that are not in a fixed position can be deformed, thereby changing the size of the elastic force, thereby completing the adjustment of the elastic force. When it is necessary to fix the fitting frame 43 and the fixing frame 41 together, the external long rod is passed through the vertical hole 49 on the top and inserted into the vertical hole 49 on the fixing frame 41. At this time, the fitting frame 43 and the fixing frame 41 are in a fixed state, so the fixation of the two can be completed, ensuring the stability of use.
