Detailed Embodiments

[0022] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0025] The present utility model will be further described in detail below with reference to the drawings.

[0026] Please refer to Figure 1 and Figure 2 , which is a grooving positioning structure 100 provided by an embodiment of the present utility model, including a mounting portion 10, a positioning portion 20, and a roller 30.

[0027] Among them, the mounting portion 10 is used for mounting with the machine table; the positioning portion 20 is connected to the mounting portion 10, and an arc-shaped notch 21 is provided on the positioning portion 20; the roller 30 is installed in the positioning portion 20, and along the radial direction of the roller 30, part of the roller 30 protrudes from the side wall of the arc-shaped notch 21 and is used for fitting and rotating with the cylindrical shell.

[0028] For the above-mentioned grooving positioning structure 100, by providing an arc-shaped notch 21 on the positioning portion 20, the cylindrical shell can be arranged in the arc-shaped notch 21 during grooving, and a roller 30 is provided in the positioning portion 20, and the roller 30 protrudes from the side wall of the arc-shaped notch 21. In this way, when grooving the cylindrical shell, the roller 30 contacts and rotates with the cylindrical shell, so that the sliding friction between the cylindrical shell and the positioning portion 20 in the prior art is changed into rolling friction, reducing the contact area between the cylindrical shell and the positioning portion 20 and reducing the frictional damage to the cylindrical shell.

[0029] Specifically, the arc-shaped notch 21 in this embodiment is set in a C shape, that is, the central angle is 180 degrees, and the curvature of the arc-shaped notch 21 is the same as the curvature of the transverse section of the cylindrical shell. When the circular shell is arranged in the arc-shaped notch 21, it can just surround half of the cylindrical shell, so that the side wall of the arc-shaped notch 21 has enough extension length to facilitate the selection of the installation position of the roller 30 on the mounting portion 20, thereby ensuring the balance of the roller 30 after applying force to the arc-shaped shell.

[0030] Further, to ensure the balance of the applied force on the cylindrical shell, the rolling groove positioning structure 100 includes at least two rollers 30, and one roller 30 is installed at each end of the positioning portion 20 along the maximum length direction of the arc-shaped notch 21. When the rollers 30 and the cylindrical shell exert mutual forces, balanced forces can be applied to the cylindrical shell to avoid the situation where the rollers 30 press depressions on the cylindrical shell. In other embodiments, other numbers of rollers 30 can also be set, such as three or four. It should be noted that when multiple rollers 30 are provided on the mounting portion 20, the multiple rollers 30 need to be evenly arranged.

[0031] Among them, the maximum length direction of the arc-shaped notch 21 referred to in this embodiment refers to the direction of the connection line between the two ends of the side wall of the arc-shaped notch 21.

[0032] Further, when installing the rollers 30, a through groove 22 is provided in the positioning portion 20. The through groove 22 communicates with the arc-shaped notch 21. The rollers 30 are installed in the through groove 22, and the through groove 22 penetrates the positioning portion 20 along the maximum length direction of the arc-shaped notch 21. In this way, compared with the method of only opening an installation groove 23 at the position where the rollers 30 are installed on the positioning portion 20, the situation of scratching the cylindrical shell due to the formation of a step on the side wall of the arc-shaped notch 21 after opening the installation groove 23 is avoided; at the same time, the method of only opening one through groove 22 facilitates the formation of the through groove 22 on the positioning portion 20.

[0033] It can be understood that since the cylindrical shell has a certain height, to ensure the positioning of the cylindrical shell, along the axial direction of the cylindrical shell, the rolling groove positioning structure 100 includes at least two positioning portions 20, and the positioning portions 20 are separated from each other. By setting multiple positioning portions 20, along the axial direction of the cylindrical shell, more rollers 30 can be in contact with the cylinder for positioning, avoiding the situation where the cylindrical shell is skewed.

[0034] Specifically, this embodiment includes two positioning portions 20. One positioning portion 20 is arranged close to one end of the cylindrical shell. That is, the rollers 30 on the two positioning portions 20 exert forces on the two ends of the cylindrical shell to support the ends, thereby ensuring the stability of the cylindrical shell during the rolling groove process.

[0035] Further, along the axial direction of the cylindrical shell and from top to bottom, the thickness of the positioning portion 20 gradually increases. Since the positioning portion 20 located below needs to bear greater pressure, setting a thicker thickness for the positioning portion 20 located below can increase the structural strength of the positioning portion 20.

[0036] Among them, along the axial direction of the cylindrical shell, the thickness of the positioning portion 20 in this embodiment is between 15 mm and 20 mm. Through this thickness setting, the structural strength of each positioning portion 20 can be ensured, and it can be adapted to the height of the cylindrical shell. At the same time, multiple positioning portions 20 can be provided.

[0037] For example, the thickness of the positioning portion 20 can be set to values such as 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm according to the models of different cylindrical shells, which is not limited here.

[0038] In addition, since the thickness of the positioning portion 20 gradually increases in the direction from top to bottom, when two positioning portions 20 are provided, the upper positioning portion 20 can be set to 15 mm, and the lower positioning portion 20 can be set to 20 mm.

[0039] Please refer to Figure 1 and Figure 2 , since the cylindrical shell needs to go from the previous production process to the rolling groove process, in order to position the cylindrical shell, the rolling groove positioning structure 100 further includes a magnetic member 40. The magnetic member 40 is installed on the positioning portion 20 to be able to apply a magnetic force to the cylindrical shell. Thus, through the setting of the magnetic member 40, when the cylindrical shell flows from the previous process, the magnetic member 40 can generate a magnetic force on the cylindrical shell to attract the cylindrical shell, so that the cylindrical shell can be kept in a vertical state when in the rolling groove process.

[0040] Specifically, an installation groove 23 is provided on the positioning portion 20, and the installation groove 23 extends to the surface of the positioning portion 20 along the direction perpendicular to the axial direction of the cylindrical shell, so as to facilitate the installation of the magnetic member 40; further, due to the setting of the through groove 22, part of the material of the positioning portion 20 is dug out to reduce the barrier between the magnetic member 40 and the cylindrical shell and ensure the magnetic force applied by the magnetic member 40 to the cylindrical shell.

[0041] Among them, when the positioning portion 20 in this embodiment is installed, it is installed on the installation portion 10 in a detachable manner. Specifically, the bolt method is adopted, so as to facilitate the replacement of the positioning portion 20 after wear and the assembly between the positioning portion 20 and the installation portion 10.

[0042] Please refer to Figure 1 and Figure 2 , when installing the entire rolling groove positioning structure 100, the installation portion 10 includes a horizontally installed block 11 and a vertically installed block 12 that are perpendicularly arranged. The horizontally installed block 11 is used to connect to the machine table, and the positioning portion 20 is installed on the vertically installed block 12. In this way, through the setting of the two-part installation portion 10, since there is a vertically installed block 12 in a vertical state, multiple positioning portions 20 can be installed on the vertically installed block 12 in the direction from top to bottom.

[0043] Among them, the width of the horizontal mounting block 11 along the maximum length direction of the arc-shaped notch 21 is greater than the width of the vertical mounting block 12, so that a mounting hole 111 can be provided on the horizontal mounting block 11, and the entire rolling groove positioning structure 100 can be mounted on the machine table through the mounting hole 111.

[0044] Furthermore, since the rolling groove wheel needs to pass over the positioning portion 20 located at the uppermost position to be able to contact the circular housing, so as to realize the bending of part of the cylindrical housing. In order to avoid the mounting screw of the rolling groove wheel, a relief notch 121 is provided at one end of the vertical mounting block 12 away from the horizontal mounting block 11 and on the side facing away from the positioning portion 20, so as to achieve the relief effect through the relief notch 121.

[0045] The above-mentioned rolling groove positioning structure 100 can position the cylindrical housing through the plurality of rollers 30 on the plurality of positioning portions 20 by setting a plurality of positioning portions 20 on the mounting portion 10, so as to avoid the situation that the cylindrical housing is skewed during the rolling groove process; by further providing a magnetic member 40 on the positioning portion 20, when the cylindrical housing is moved from the previous process to the rolling groove process, the magnetic force generated by the magnetic member 40 on the cylindrical housing can keep the cylindrical housing in a vertical state.

[0046] In another embodiment of the present invention, a rolling groove device is further provided, which includes the above-mentioned rolling groove positioning structure 100.

[0047] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present invention.
