Technical Field

[0001] This utility model relates to the field of root cleaning technology, and more specifically, to a root cleaning device for circumferential weld seams of cylindrical containers. Background Technology

[0002] Root cleaning refers to the removal of root defects in the reverse weld after the root pass weld is completed, for double-sided welds with high quality requirements.

[0003] For cleaning the root of circumferential welds on cylindrical containers, the container is clamped in a fixture, and a root cleaning device (using a milling cutter, file, grinding wheel, etc.) is installed on one side of the container. The root cleaning of the circumferential weld is completed by rotating the container once. However, some cylindrical containers have cross-sections that are not standard circles but have a certain degree of ellipticity, and existing root cleaning devices are difficult to adapt to changes in the ellipticity of the container. Utility Model Content

Detailed Implementation

[0023] refer to Figure 1 and Figure 2 A device for cleaning the circumferential weld seam of a cylindrical container includes a milling cutter 2 and a drive assembly for driving the milling cutter 2 to rotate. Specifically, a drive shaft is centrally connected to the milling cutter 2. The drive assembly can be a motor driving the drive shaft to rotate via a belt reduction transmission, or a motor driving the drive shaft to rotate via a gear reducer. In practical applications, the axis of the drive shaft is parallel to the axis of the cylindrical container to be cleaned, and the outer periphery of the milling cutter 2 is directly opposite the cleaning area.

[0024] The root cleaning device also includes a frame 1, a fixing plate 3, a first sliding plate 4, a second sliding plate 5, and a cylinder diameter tracking mechanism 6.

[0025] The fixed plate 3 is located on the top of the frame 1. The first slide plate 4 is slidably located on the top of the fixed plate 3. The second slide plate 5 is slidably located on the top of the first slide plate 4. The milling cutter 2 and its drive assembly are located at one end of the top of the second slide plate 5. The sliding direction of the first slide plate 4 is perpendicular to the sliding direction of the second slide plate 5, so that the position of the milling cutter 2 can be adjusted in two mutually perpendicular directions. That is, during operation, the position of the milling cutter 2 in the axial direction of the cylindrical container can be adjusted to locate the root cleaning position; the distance between the milling cutter 2 and the side wall of the cylindrical container can also be adjusted according to the diameter of the cylinder.

[0026] Alternatively, the fixed plate 3 is provided with a first lead screw and nut mechanism for adjusting the position of the first slide plate 4, and the first slide plate 4 is provided with a second lead screw and nut mechanism for adjusting the position of the second slide plate 5. In practical applications, the first and second lead screw and nut mechanisms can also be connected to a motor to achieve automatic adjustment of the position of the milling cutter 2. It should be understood that in other embodiments, the sliding of the first slide plate 4 and the second slide plate 5 can of course be achieved in other ways.

[0027] The cylinder diameter tracking mechanism 6 is fixedly mounted on one side of the milling cutter 2 in the axial direction, and is used to abut against the cylinder. It generates displacement changes according to the diameter changes of the cylinder, thereby facilitating accurate adjustment of the distance between the milling cutter 2 and the side wall of the cylindrical container based on the amount of displacement change. This allows the present invention to be applied to cylindrical containers with elliptic shapes. As an alternative, the specific structure of the cylinder diameter tracking mechanism 6 in this embodiment is as follows (see reference). Figure 3 The cylinder diameter tracking mechanism 6 includes a contact roller 601, a guide rod 602, a sleeve 603, a spring 604, and a scale 605. The sleeve 603 is fixedly mounted on the housing of the drive assembly (or it can be fixedly mounted on the second slide plate 5). The guide rod 602 passes through the cylinder and one end extends out of the sleeve 603. The contact roller 601 is located at the outer end of the guide rod 602. A stop block is provided at the inner end of the guide rod 602. The spring 604 is located inside the sleeve 603. One end of the spring 604 abuts against the end of the sleeve away from the contact roller 601, and the other end of the spring 604 abuts against the stop block. The scale 605 is located at the top of the sleeve 603. A pointer 606 extending out of the top of the sleeve 603 is provided on the guide rod 602 (it should be understood that the top of the sleeve 603 is provided with a relief groove to avoid the pointer 606) for indicating the scale on the scale 605. In practical applications, after adjusting the distance between the milling cutter 2 and the cylinder, the contact roller 601 contacts the side wall of the cylinder and the spring 604 is compressed. The scale indicated by the pointer 606 at this time is recorded as the initial scale. When cleaning the root, the cylinder rotates slowly. If the scale changes, the position of the milling cutter 2 is adjusted so that the scale always remains at the above initial scale, which can adapt to the change in the diameter of the cylinder and ensure the quality of root cleaning.

[0028] A laser pointer 7 for indicating the weld position is provided below the milling cutter 2 (or above it in other embodiments). This laser pointer 7, also called a laser indicator, emits a beam of light to form a spot at the target location. Preferably, the laser pointer 7 emits red light. It is worth noting that the purpose of the laser pointer 7 is to illuminate the weld position to form a spot, indicating the location for root cleaning. During root cleaning, if the spot deviates, the position of the milling cutter 2 is adjusted promptly to ensure the quality of root cleaning.

[0029] In this embodiment, the laser pointer 7 is installed as follows: a mounting bracket 9 is fixedly connected to the top of the second sliding plate 5, and a pen holder 8 is fixedly mounted on the mounting bracket 9. The laser pointer 7 is installed inside the pen holder 8. Further, refer to... Figure 4The pen holder 8 includes a ball seat 801, a ball 802, and a pressure cap 803. One end of the ball seat 801 is fixedly connected to the mounting bracket 9, and the other end of the ball seat 801 has a ball hole. The ball 802 is rotatably disposed in the ball hole. The pressure cap 803 is threadedly connected to the ball seat 801 to press the ball 802. The ball 802 has a mounting hole, into which the laser pointer 7 is inserted. It is worth noting that this design allows the illumination position of the laser pointer 7 to be adjusted by rotating the ball head, making it easier to adjust the illumination direction of the laser pointer 7 and to make the light spot fall on the weld seam. After adjustment, the pressure cap 803 is tightened to fix the ball head.

[0030] In this embodiment, a height adjustment component for adjusting the height of the milling cutter 2 is provided between the fixed plate 3 and the frame 1, which facilitates the use of cylindrical containers of different diameters. Alternatively, in this embodiment, the height adjustment component includes a jack 10, which is fixed to the frame 1. The jack 10's head is hinged to one end of the fixed plate 3 near the milling cutter 2, and the other end of the fixed plate 3 is fixedly hinged to the frame 1. In use, the milling cutter 2 can be rotated downwards or upwards by extending or retracting the jack 10's head, thereby adjusting its height. It is worth noting that using the jack 10 for height adjustment not only provides self-locking but also simplifies operation and increases accuracy. In other embodiments, other conventional lifting mechanisms in the art can also be used to adjust the height of the milling cutter 2.

[0031] As an alternative, in this embodiment, the jack 10's head is hinged to the fixed plate 3 as follows, see reference. Figure 5 The jack 10 has a lower connecting seat 11 fixedly connected to its top end. A first supporting shaft 12 passes through the lower connecting seat 11. An upper connecting seat 13 is fixedly connected to the bottom of the fixed plate 3. A second supporting shaft 14 passes through the upper connecting seat 13. A connecting plate 15 is provided between the upper connecting seat 13 and the lower connecting seat 11. The upper end of the connecting plate 15 is sleeved on the second supporting shaft 14, and the lower end of the connecting plate 15 is sleeved on the first supporting shaft 12. It is easy to understand that in other embodiments, the way the top end of the jack 10 is movably hinged to the fixed plate 3 can also take other forms. For example, the fixed plate 3 has a groove, and a sliding hinge rod is provided in the groove. The top end of the jack 10 is rotatably connected to the sliding hinge rod. In this embodiment, the specific way the other end of the fixed plate 3 is fixedly hinged to the frame 1 is not limited. For example, a hinge shaft is rotatably provided on the fixed plate 3, and the hinge shaft also passes through the frame 1.

[0032] In addition, in practical applications, casters 101 can be installed at the bottom of the frame 1 to facilitate the relocation of the root clearing device. Specifically, two swivel casters 101 and two fixed casters 101 can be installed.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 lies in the specific structure of the cylinder diameter tracking mechanism 6. In this embodiment, the cylinder diameter tracking mechanism 6 is a self-resetting electronic ruler. It should be understood that an electronic ruler is an electronic component used to measure displacement, also called a displacement sensor, which can be purchased directly from the market, such as the Jefferson PY-2 self-resetting displacement sensor, equipped with a digital display. When used in this utility model, its measuring rod abuts against the side wall of the cylinder, and the reset element is compressed. When the cylinder diameter decreases, the reset element extends, and when the cylinder diameter increases, the reset element is further compressed. The position of the milling cutter 2 is adjusted according to the specific displacement change. In addition, when the first slider and the second slider are adjusted by rotating the motor, a control system can also be configured to automatically control the motor to work according to the displacement change of the electronic ruler, so as to achieve automatic adjustment.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
