Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] The utility model proposes a cylindrical shell end face observation device, which aims to solve the problem that conventional observation devices cannot adapt to cylindrical shells of various diameters at the same time, and cannot control the moving speed of the limiting mechanism according to the diameter of the cylindrical shell, so as to shorten the time for loading and positioning the cylindrical shell and improve work efficiency.

[0043] See also Figures 1 to 6In one embodiment of the present invention, the cylindrical shell end face observation device 100 includes a lifting platform 1, a shell detection mechanism 2, a limiting mechanism 3, a rotation drive mechanism 4 and an end face observation mechanism 5. The lifting platform 1 is movably arranged in the vertical direction. The lifting platform 1 is used to carry the loaded cylindrical shell and drive the cylindrical shell to move in the vertical direction. The shell detection mechanism 2 and the lifting platform 1 are arranged at intervals. The shell detection mechanism 2 is used to detect the diameter of the cylindrical shell during the process of loading the cylindrical shell onto the lifting platform 1. The limiting mechanism 3 includes two limiting components 31 arranged at intervals along the transverse direction. Each limiting component 31 is arranged on the lifting platform 1 for movement along the transverse direction, and the two limiting components 31 are used to move close to each other after the cylindrical shell is loaded onto the lifting platform 1, and decelerate in advance according to the diameter of the cylindrical shell during the movement to jointly clamp the cylindrical shell. The rotation drive mechanism 4 is arranged above the lifting platform 1. The rotation drive mechanism 4 abuts against the upper end of the cylindrical shell during the process of the lifting platform 1 driving the cylindrical shell to move upward, and drives the cylindrical shell to rotate around the longitudinally extending axis L1 as the rotation axis. The end face observation mechanism 5 and the rotation drive mechanism 4 are arranged at intervals. The end face observation mechanism 5 is used to observe the end face of the cylindrical shell during the process of the rotation drive mechanism 4 driving the cylindrical shell to rotate.

[0044] In the technical solution of the present utility model, the cylindrical shell is first loaded onto the lifting platform 1 so that the lifting platform 1 carries the cylindrical shell. At the same time, the shell detection mechanism 2 can detect the end face diameter of the cylindrical shell during the process of loading the cylindrical shell onto the lifting platform 1. After the cylindrical shell is loaded, the two limit assemblies 31 move toward each other, and during the movement of the two limit assemblies 31, the two limit assemblies 31 decelerate in advance according to the end face diameter of the cylindrical shell, and stop moving when they contact the side of the cylindrical shell to jointly clamp the cylindrical shell. After the clamping is completed, the lifting platform 1 moves in the vertical direction until the cylindrical shell and the rotation drive mechanism 4 abut against each other. The rotation drive mechanism 4 works to drive the cylindrical shell to rotate with the longitudinally extended axis as the rotation axis. During the process of the cylindrical shell rotating with the longitudinally extended axis as the rotation axis, the end face observation mechanism 5 will take a picture of the end face of the cylindrical shell to observe whether there are cutting defects or sealing welding quality problems in the appearance of the end face of the cylindrical shell. The two movable limit assemblies 31 enable the cylindrical shell end face observation device 100 to adapt to cylindrical shells of various diameters, and control the moving speed of the limit assemblies 31 according to the diameter of the cylindrical shell, thereby reducing the time for loading and positioning the cylindrical shell and improving the working efficiency of the cylindrical shell end face observation device 100.

[0045] It should be noted that in order to ensure that the end face observation mechanism 5 can observe a clear image of the end face of the cylindrical shell and further improve the image quality, it is necessary not only to limit the horizontal position of the cylindrical shell, but also to further limit the vertical position of the cylindrical shell. In one embodiment of the present invention, the cylindrical shell end face observation device 100 also includes a shell in-place detection mechanism 6. The shell in-place detection mechanism 6 is provided on one side of the lifting platform 1 in the longitudinal direction. The shell in-place detection mechanism 6 is used to detect the longitudinal position of the cylindrical shell during the process of loading the cylindrical shell onto the lifting platform 1. In this way, the loading process will be stopped only when the in-place detection mechanism 6 detects that the longitudinal position of the cylindrical shell is in a qualified position, and then the two limit assemblies 31 move closer to each other to jointly clamp the cylindrical shell.

[0046] The present invention does not limit the specific structural form of the in-place detection mechanism 6. In one embodiment of the present invention, the in-place detection mechanism 6 can be set as a distance sensor, and the distance sensor detects the distance between itself and the cylindrical shell to detect the longitudinal position of the cylindrical shell.

[0047] In other embodiments of the present invention, the in-position detection mechanism 6 can also be configured as an image acquisition structure, which determines the longitudinal position of the cylindrical shell by acquiring an image of the end face of the cylindrical shell.

[0048] Further, see Figure 6 In the process of loading the cylindrical shell onto the lifting platform 1, the cylindrical shell will move on the lifting platform 1. In order to ensure the stability of the lifting platform 1 in supporting the cylindrical shell, in one embodiment of the present utility model, the lifting platform 1 includes a platform body 11 and a bearing part 13. The platform body 11 is movably arranged in the vertical direction. The upper end surface of the platform body 11 is provided with a bearing limiting groove 12 extending in the vertical direction. The bearing part 13 is arranged in the bearing limiting groove 12 and protrudes from the upper end surface of the platform body 11. The bearing part 13 is elastically arranged in the vertical direction. The bearing part 13 is used to carry the loaded cylindrical shell and undergoes elastic deformation when carrying the cylindrical shell. In this arrangement, the bearing portion 13 is used to bear the cylindrical shell, and when the bearing portion 13 bears the cylindrical shell, the bearing portion 13 will be subjected to the pressure of the cylindrical shell and thus elastically deform downward, and the portion of the bearing portion 13 close to the center line of the cylindrical shell is subjected to greater pressure, so its elastic deformation is greater, so that more parts of the bearing portion 13 can support the cylindrical shell, thereby ensuring the support of the lifting platform 1 for the cylindrical shell.

[0049] Of course, the present invention does not limit the specific form of the bearing portion 13. In one embodiment of the present invention, the bearing portion 13 can be configured as a plurality of springs arranged at intervals in the transverse and longitudinal directions, and each of the springs is extended in the vertical direction. When the cylindrical shell is loaded onto the plurality of springs, the deformation of the springs close to the centerline position of the cylindrical shell is greater than the deformation of the springs close to the boundary position, thereby increasing the number of springs in contact with the cylindrical shell and achieving the purpose of the plurality of springs jointly supporting the cylindrical shell.

[0050] In another embodiment of the present invention, the bearing portion 13 can also be configured as a rubber block, which is elastically configured in the vertical direction. When the cylindrical shell is loaded onto the rubber block, the rubber block will be subjected to the pressure of the cylindrical shell and elastically deformed. The deformation of the rubber block near the center line of the cylindrical shell is greater than the deformation of the rubber block near the boundary position, thereby increasing the contact area between the rubber block and the cylindrical shell, thereby ensuring the supporting effect of the rubber block on the cylindrical shell.

[0051] At the same time, if Figure 6 In the process of loading the cylindrical shell onto the bearing part 13, the cylindrical shell needs to move on the bearing part 13 in the longitudinal direction. In order to ensure the smooth movement of the cylindrical shell in the longitudinal direction and prevent the cylindrical shell and the bearing part 13 from rubbing against each other, which makes it unable to move to the correct position in the longitudinal direction, in one embodiment of the present utility model, a plurality of bearing limit grooves 12 are provided, and the plurality of limit grooves are arranged at intervals in the transverse and longitudinal directions. Each bearing part 13 includes an elastic member 131 and a rolling member 132. The elastic member 131 is arranged in the bearing limit groove 12, and the elastic member 131 is elastically arranged in the vertical direction. The rolling member 132 is configured to be rotatable with a transversely extending axis as a rotating axis and is arranged at the upper end of the elastic member 131. The rolling member 132 is used to roll in contact with the cylindrical shell and roll synchronously with the cylindrical shell during the loading process of the cylindrical shell. With such arrangement, during the loading process of the cylindrical shell, the rolling element 132 will roll along with the longitudinal movement of the cylindrical shell, so as to reduce the friction force on the cylindrical shell during the longitudinal movement and ensure the smooth movement of the cylindrical shell.

[0052] The present invention does not limit the specific form of the rolling element 132. In one embodiment of the present invention, the rolling element 132 includes a roller shaft extending in the transverse direction, and the roller shaft is rotatably connected to the elastic element 131. In this way, during the loading process of the cylindrical shell, the roller shaft can rotate with the transversely extending axis as the rotating axis, so as to roll synchronously with the cylindrical shell when the cylindrical shell is loaded, so as to change the sliding friction of the cylindrical shell into rolling friction, reduce the friction force of the cylindrical shell when it moves in the longitudinal direction, and ensure the smoothness of the movement of the cylindrical shell.

[0053] In another embodiment of the present invention, the rolling element 132 is configured as a sphere and is arranged to rotate freely on the upper end of the elastic element 131. Such configuration enables the rolling element 132 to not only rotate synchronously with the cylindrical shell with the transversely extending axis as the rotation axis during the loading process of the cylindrical shell, but also when the rotation drive mechanism 4 drives the cylindrical shell to rotate with the longitudinally extending axis as the rotation axis, the rolling body can also rotate synchronously with the cylindrical shell. Such configuration enables the rolling body to rotate freely with axes in multiple directions as the rotation axis. Regardless of whether the cylindrical shell is being loaded or the rotation drive mechanism 4 drives the cylindrical shell to rotate, the rolling element 132 can rotate synchronously with the cylindrical shell, further improving the smoothness of the cylindrical shell movement.

[0054] It should be noted that, in this embodiment, the rolling element 132 is configured as a sphere.

[0055] It can be understood that the present invention does not limit the specific activity form of the two limit assemblies 31. For example, in one embodiment of the present invention, the two limit assemblies 31 can be set to slide horizontally on the lifting platform 1; and in another embodiment of the present invention, the two limit assemblies 31 can be set to rotate along the axis extending longitudinally on the lifting platform 1 as a rotating shaft. At this time, one end of the two limit assemblies 31 is fixed, and the other end can move close to each other. In this way, the two limit assemblies 31 can be moved close to each other.

[0056] Of course, in other embodiments of the present invention, the two limit assemblies 31 may also be configured as other structural forms, which can be selected according to actual needs during the actual configuration, and the present invention does not impose any restrictions on this.

[0057] Specifically, see Figure 3In the present utility model, each of the limiting components 31 includes a limiting portion 311 and a rolling portion 312. The limiting portion 311 is movably arranged on the lifting platform 1 along the horizontal direction, and the rolling portion 312 is configured to be rotatably installed on the limiting portion 311 with the longitudinally extending axis as the rotation axis. The rolling portion 312 is used to roll in contact with the cylindrical shell so as to roll synchronously with the cylindrical shell during the rotation of the cylindrical shell. With such arrangement, after the cylindrical shell is loaded onto the lifting platform 1, the two limiting parts 311 move close to each other and decelerate in advance according to the diameter of the cylindrical shell during the movement until the corresponding rolling part 312 abuts against the cylindrical shell, and each limiting part 311 stops moving. When the rotation drive mechanism 4 drives the cylindrical shell to rotate with the longitudinally extended axis as the axis, due to the rolling structure of the two rolling parts 312 and the cylindrical shell, the two rolling parts 312 will be driven by the cylindrical shell to roll synchronously with the cylindrical shell, so that when the cylindrical shell rotates with the longitudinally extended axis as the axis, it not only provides support for the cylindrical shell, but also reduces the friction force encountered by the cylindrical shell during rolling, reduces the resistance encountered by the cylindrical shell during rolling, and ensures the smoothness of rolling.

[0058] It should be noted that the present invention does not limit the specific rolling form of the rolling portion 312. In one embodiment of the present invention, the rolling portion 312 is configured as a roller, and the roller is extended along the longitudinal direction, and the roller is rotatably connected to the limiting portion 311 at both ends in the longitudinal direction. In this manner, the limiting portion 311 provides sufficient supporting force for the rolling portion 312, and at the same time, does not limit the synchronous rotation of the rolling portion 312 and the cylindrical shell, thereby ensuring the smoothness of the rolling of the cylindrical shell.

[0059] In another embodiment of the present invention, the rolling portion 312 can also be configured as a plurality of balls arranged at intervals along the longitudinal direction, each of the balls having a through hole extending longitudinally, and the rolling portion 312 also includes a rotating shaft extending longitudinally, the rotating shaft passes through the through holes of the plurality of balls in sequence, and both ends are fixedly connected to the limiting portion 311. In this manner, the limiting portion 311 and the rotating shaft provide supporting force, and the plurality of balls will jointly roll in contact with the cylindrical shell. When the rotation drive mechanism 4 drives the cylindrical shell to rotate with the longitudinally extending axis as the rotating axis, the plurality of balls will also roll synchronously with the cylindrical shell, thereby ensuring the smoothness of the rolling of the cylindrical shell.

[0060] Of course, in other embodiments of the present invention, the rolling portion 312 may also be configured as other structural forms, which may be selected according to actual needs, and the present invention does not impose any restrictions on this.

[0061] Specifically, it can be understood that before the two limiting parts 311 drive the corresponding rolling parts 312 to approach each other, the two limiting parts 311 are in a stationary state. Therefore, in the process of the two limiting parts 311 driving the corresponding rolling parts 312 to approach each other, the two limiting parts 311 can have multiple motion modes. First of all, it should be noted that the diameter of the cylindrical shell is D, and the cylindrical shell has a deceleration starting distance X on both sides in the horizontal direction. When the distance between the two limiting parts 311 and the cylindrical shell is not greater than X, each limiting part 311 needs to start decelerating. In this way, in one embodiment of the present utility model, the two limiting parts 311 are As the limiting parts 311 approach each other, they first accelerate continuously at a constant acceleration a1 until the speeds of both limiting parts 311 reach a rated speed V1. At these times, the limiting parts 311 stop accelerating and continue approaching each other at the rated speed V1 until the distance between the limiting parts 311 is reduced to D+2X. At these times, the limiting parts 311 need to decelerate at a constant acceleration a2 until the two rolling parts 312 abut the sides of the cylindrical shell. At these times, the limiting parts 311 stop moving, allowing the two rolling parts 312 to jointly clamp the cylindrical shell, thereby completing the lateral positioning of the cylindrical shell. This configuration can reduce the time required for loading and positioning the cylindrical shell and improve the working efficiency of the cylindrical shell end face observation device.

[0062] In another embodiment of the present invention, when the two limiting portions 311 approach each other, they first accelerate continuously at a constant acceleration a3 until the distance between the two limiting portions 311 is reduced to D+2X. Then, the two limiting portions 311 decelerate at a constant acceleration a4, so that the two limiting portions 311 can stop moving when the corresponding rolling portions 312 abut the side of the cylindrical shell, ensuring that the two rolling portions 312 can jointly clamp the cylindrical shell and complete the lateral positioning of the cylindrical shell. In this way, the loading and positioning time of the cylindrical shell can also be reduced, thereby improving the working efficiency of the cylindrical shell end surface observation device.

[0063] It will be understood that the present invention does not limit the specific values of a1, a2, a3, a4, V1 and X, that is, the ranges of a1, a2, a3, a4, V1 and X can be set according to actual conditions. For example, in one embodiment of the present invention, X can be set to 3 mm.

[0064] Similarly, it should be noted that in other embodiments of the present invention, the two limiting parts 311 can also accelerate at a certain variable acceleration, or decelerate at a certain variable acceleration. In actual settings, it can be selected according to needs, and the present invention does not impose any restrictions on this.

[0065] In addition, when the rolling portion 312 contacts the cylindrical shell, in order to ensure that the rolling portion 312 can provide stable supporting force and limit the role, a certain pressure is required between the rolling portion 312 and the cylindrical shell. In order to ensure the smoothness of the rolling of the cylindrical shell and the integrity of the appearance of the cylindrical shell, the pressure between the rolling portion 312 and the cylindrical shell cannot exceed a certain threshold. Therefore, in one embodiment of the present utility model, the limiting component 31 also includes a first pressure sensor 313, which is arranged between the limiting portion 311 and the rolling portion 312. The first pressure sensor 313 is used to detect the pressure on the rolling portion 312 when the rolling portion 312 contacts the cylindrical shell. In this arrangement, when the two limiting parts 311 move toward each other to drive the rolling part 312 to contact the cylindrical shell, the first pressure sensor 313 will be subjected to the pressure exerted on it by the rolling part 312, thereby indicating its pressure value. When the pressure value applied to the first sensor reaches a certain threshold, the limiting part 311 stops moving to ensure that the pressure of the two rolling parts 312 on the cylindrical shell does not exceed the threshold, thereby ensuring that the two rolling parts 312 can meet the stable support requirements and rolling smoothness requirements of the cylindrical shell.

[0066] Of course, the present invention does not limit the specific installation position of the first pressure sensor 313. In another embodiment of the present invention, the first pressure sensor 313 can also be set on other structures. It only needs to ensure that when the rolling part 312 and the cylindrical shell are in contact, the first pressure sensor 313 can detect the pressure between the rolling part 312 and the cylindrical shell.

[0067] It can be understood that in order to further ensure that when the rolling portion 312 contacts the cylindrical shell, the squeezing of the cylindrical shell by the two rolling portions 312 will not force the cylindrical shell to deform, in one embodiment of the present invention, the rolling portion 312 is flexibly configured. With this configuration, when the rolling portion 312 contacts the cylindrical shell, the rolling portion 312 will be elastically deformed by the pressure applied by the cylindrical shell, thereby playing a buffering role during the contact process, reducing the instantaneous pressure on the cylindrical shell, and avoiding deformation of the cylindrical shell.

[0068] Similarly, in another embodiment of the present invention, the rolling portion 312 can also be configured to be wrapped with a flexible layer in its circumferential direction. In this way, the flexible layer is used to contact the cylindrical shell. During the contact between the flexible layer and the cylindrical shell, the flexible layer will be subjected to the pressure applied by the cylindrical shell and thus elastically deformed, so as to play a buffering role during the contact process and avoid deformation of the cylindrical shell during the contact process.

[0069] It can be understood that after the two limiting assemblies 31 jointly clamp the cylindrical shell, the lifting platform 1 needs to move upward in the vertical direction, so that the upper end of the cylindrical shell abuts the rotation drive mechanism 4, so that the rotation drive mechanism 4 drives the cylindrical shell to rotate. In order to ensure the movement of the lifting platform 1, in the present invention, the cylindrical shell end face observation device 100 also includes a jacking mechanism, which is arranged below the lifting platform 1 and is connected to the lifting platform 1 to drive the lifting platform 1 to move in the vertical direction. With such an arrangement, after the two limiting assemblies 31 jointly clamp the cylindrical shell, the jacking mechanism can drive the lifting platform 1 to move upward, so that the lifting platform 1 drives the cylindrical shell to move upward, so that the upper end of the cylindrical shell abuts the rotation drive mechanism 4, ensuring the stability of the lifting platform 1 in the vertical direction.

[0070] Of course, the present invention does not limit the specific form of the jacking mechanism. In one embodiment of the present invention, the jacking mechanism can be set as a jacking cylinder, and the cylinder rod of the jacking cylinder is fixedly connected to the lifting platform 1. After the two limit assemblies 31 jointly clamp the cylindrical shell, the cylinder rod of the jacking cylinder extends to drive the lifting platform 1 to move upward in the vertical direction until the upper end of the cylindrical shell and abut against the rotation drive mechanism 4; after the end face observation mechanism 5 completes the observation, the cylinder rod of the jacking cylinder contracts to drive the lifting platform 1 to move downward in the vertical direction to the initial position.

[0071] In another embodiment of the present invention, the lifting mechanism can also be provided with a ball screw structure, the screw rod of the ball screw structure is connected to the main shaft of a rotating motor, and the ball nut of the ball screw structure is fixedly connected to the lifting platform 1. After the two limit assemblies 31 jointly clamp the cylindrical shell, the rotating motor drives the screw rod of the ball screw structure to rotate, thereby driving the ball nut of the ball screw structure to move upward, and the ball nut of the ball screw structure drives the lifting platform 1 to move upward in the vertical direction until the upper end of the cylindrical shell and the rotation drive mechanism 4 abut against the rotation drive mechanism 4; after the end face observation mechanism 5 completes the observation, the rotating motor rotates in the opposite direction to drive the screw rod of the ball screw structure to rotate in the opposite direction, thereby driving the ball nut of the ball screw structure to move downward, and the ball nut of the ball screw structure drives the lifting platform 1 to move downward in the vertical direction to its initial position.

[0072] In other embodiments of the present invention, the lifting mechanism may also be configured as other structural forms, which may be selected according to actual needs during actual configuration, and the present invention does not impose any restrictions on this.

[0073] In order to ensure the stable driving of the cylindrical shell by the rotation drive mechanism 4, please refer to Figures 4 and 5 In the present invention, the rotation drive mechanism 4 includes a driving wheel 41 and a driving portion 42. The driving wheel 41 is provided above the lifting platform 1 and is capable of rotating about a longitudinally extending axis. The driving wheel 41 is used to drive the cylindrical shell to rotate when it abuts against the upper end of the cylindrical shell. The driving portion 42 is drivably connected to the driving wheel 41 to drive the driving wheel 41 to rotate about the longitudinally extending axis L2. The driving portion 42 is configured to provide driving force for the driving wheel 41. When the lifting platform 1 drives the cylindrical shell to move upward in the vertical direction until the upper end of the cylindrical shell abuts against the driving wheel 41, the driving portion 42 begins to operate, driving the driving wheel 41 to rotate about the longitudinally extending axis. The driving wheel 41 then drives the cylindrical shell to rotate about the longitudinally extending axis, thereby achieving rotation of the cylindrical shell, allowing the end face observation mechanism 5 to observe the appearance of the end face of the cylindrical shell, whether there are cutting defects, or the quality of the sealing weld.

[0074] It should be further explained that, after the two limiting assemblies 31 have completed limiting the cylindrical shell, the lifting platform 1 moves upward in the vertical direction to the upper end of the cylindrical shell and abuts against the rotation drive mechanism, thereby realizing that the rotation drive mechanism 4 drives the cylindrical shell to rotate. When the driving wheel 41 abuts against the cylindrical shell, in order to ensure that the driving wheel 41 does not squeeze the cylindrical shell to cause the cylindrical shell to deform, it is also necessary to ensure the effectiveness of the driving wheel 41 in driving the cylindrical shell to rotate. Please refer to Figure 2 In the present invention, the rotation drive mechanism 4 further includes a second pressure sensor 43, which is disposed on one side of the driving wheel 41 in the longitudinal direction. The second pressure sensor 43 is used to detect the pressure exerted on the driving wheel 41 when the driving wheel 41 contacts the cylindrical shell. With this arrangement, when the driving wheel 41 and the cylindrical shell abut against each other, the second pressure sensor 43 is subjected to the pressure exerted by the driving wheel 41, thereby indicating its pressure value. When the pressure value exerted on the second pressure sensor 43 reaches a certain threshold, the lifting platform 1 stops moving to ensure that the pressure exerted by the driving wheel 41 on the cylindrical shell does not exceed the threshold, thereby ensuring that the driving wheel 41 can effectively drive the cylindrical shell without squeezing the cylindrical shell to cause deformation.

[0075] Similarly, the present invention does not limit the specific installation position of the second pressure sensor 43. In another embodiment of the present invention, the second pressure sensor 43 can also be set on other structures. It only needs to ensure that when the driving wheel 41 and the cylindrical shell are in contact, the second pressure sensor 43 can detect the pressure between the driving wheel 41 and the cylindrical shell.

[0076] It can be understood that in order to further ensure that when the driving wheel 41 contacts the cylindrical shell, the squeezing of the cylindrical shell by the driving wheel 41 will not force the cylindrical shell to deform, in one embodiment of the present utility model, the driving wheel 41 is flexibly configured. With this configuration, when the driving wheel 41 contacts the cylindrical shell, the driving wheel 41 will be subjected to the pressure applied by the cylindrical shell and thus elastically deformed, so as to act as an airway buffer during the contact process, increase the contact area between the driving wheel 41 and the cylindrical shell, reduce the instantaneous pressure on the cylindrical shell, and avoid deformation of the cylindrical shell.

[0077] In another embodiment of the present invention, the driving wheel 41 can also be configured to include a flexible layer in its axial direction. In this way, the flexible layer is used to contact the cylindrical shell. During the contact between the flexible layer and the cylindrical shell, the flexible layer will be subjected to the pressure applied by the cylindrical shell and thus elastically deformed, so as to play a buffering role during the contact process, increase the contact area between itself and the cylindrical shell, reduce the instantaneous pressure on the cylindrical shell, and avoid deformation of the cylindrical shell.

[0078] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
