Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, and in particular to a cylindrical centerline positioning device. Background Technology

[0002] During engineering construction, it is often necessary to install a cylinder vertically on a specific workpiece and ensure the perpendicularity of the cylinder's central axis to the specific workpiece. For example, the rotary sail used on large ships has high requirements for the perpendicularity accuracy of the fiberglass cylinder relative to the ship's hull due to its high-speed rotation characteristics. Therefore, it is necessary to locate the central axis of the fiberglass cylinder to determine whether the perpendicularity accuracy of the fiberglass cylinder relative to the ship's hull meets the accuracy requirements.

[0003] Currently, the positioning of the central axis of the cylinder mainly relies on manual marking and plumb line positioning. The positioning process is complex, inefficient, and has poor accuracy, which cannot meet the construction requirements.

[0004] Therefore, there is an urgent need for a cylindrical central axis positioning device to solve the above problems. Utility Model Content

[0009] An inner wall pressing assembly is slidably connected to the frame. Two inner wall pressing assemblies are symmetrically arranged along the central axis of the frame. The two pressing assemblies can move away from each other in the horizontal direction to press against the inner wall or move closer to each other to move away from the inner wall.

The first mounting bracket includes a support and a slide rod. The shaft of the first rotating wheel is rotatably connected to the support. The support is fixedly connected to one end of the slide rod, and the slide rod is slidably connected to the frame through the linear bearing.

[0013] In some embodiments, the cylindrical central axis positioning device further includes a first push-pull clamp, which is mounted on the frame. The output shaft of the first push-pull clamp is connected to the inner wall pressing assembly. The number of the first push-pull clamps is the same as the number of the inner wall pressing assemblies and they are connected in a one-to-one correspondence.

[0014] In some embodiments, the cylindrical central axis positioning device further includes a first flange face pressing assembly, which includes a second mounting bracket and a second rotating wheel. The second mounting bracket is mounted on the frame, and the rotating shaft of the second rotating wheel is rotatably connected to the second mounting bracket.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Figure 1 A schematic diagram of the cylindrical centerline positioning device provided in this embodiment is shown. Figure 2 It shows Figure 1 A magnified view of a portion of point A in the diagram. (See diagram below.) Figures 1 to 2 As shown, this embodiment provides a cylindrical central axis positioning device for positioning the central axis of a cylindrical body 100. The cylindrical body 100 includes an inner wall 101 and a first flange surface 102 and a second flange surface 103 that are opposite to each other and spaced apart. The cylindrical central axis positioning device includes a frame 1, an inner wall pressing assembly 2, and a total station reflector 3. The frame 1 overlaps the first flange surface 102, and the inner wall pressing assembly 2 is slidably connected to the frame 1. The two inner wall pressing assemblies 2 are symmetrically arranged along the central axis of the frame 1. The two inner wall pressing assemblies 2 can move away from each other in the horizontal direction to press against the inner wall 101 or move closer to each other to move away from the inner wall 101. The total station reflector 3 is mounted on the frame 1 and located at the central axis of the frame 1.

[0039] The cylindrical centerline positioning device provided in this embodiment is configured such that a frame 1 is attached to a first flange surface 102, and an inner wall pressing component 2 is slidably connected to the frame 1. The two inner wall pressing components 2 are symmetrically arranged along the central axis of the frame 1. The two inner wall pressing components 2 can move away from each other in the horizontal direction to press against the inner wall 101. When it is necessary to position the central axis of the cylindrical body 100, the two inner wall pressing components 2 are moved away from each other in the horizontal direction to press against the inner wall 101. The operator uses a total station to emit a laser and shine it into a reflector, which is reflected onto a receiving plate. The difference between the emission point and the reflection point is recorded. Then, the frame 1 is rotated at a specific angle along its own central axis, and the total station is used again to emit a laser and shine it into a reflector, which is reflected onto a receiving plate. The difference between the emission point and the reflection point is recorded. The frame 1 is rotated repeatedly and the difference between the emission point and the reflection point is recorded repeatedly, so that the change of the reflection point can be observed and recorded, thereby positioning the central axis of the cylindrical body 100.

[0040] Continue as Figures 1 to 2 As shown, the inner wall pressing assembly 2 includes a first mounting frame 21 and a first rotating wheel 22. The first mounting frame 21 is slidably connected to the frame 1. The rotating shaft of the first rotating wheel 22 is rotatably connected to the first mounting frame 21 and is parallel to the central axis of the cylindrical body 100. Thus, when the frame 1 is rotated, the wheel surface of the first rotating wheel 22 presses against the inner wall 101, reducing the friction between the inner wall pressing assembly 2 and the inner wall 101 of the cylindrical body 100, so as to prevent the inner wall 101 of the cylindrical body 100 from being worn.

[0041] Continue as Figures 1 to 2 As shown, the cylindrical central axis positioning device also includes a linear bearing 4, which is fixedly connected to the frame 1. The first mounting frame 21 includes a bracket 211 and a slide rod 212. The shaft of the first rotating wheel 22 is rotatably connected to the bracket 211. The bracket 211 is fixedly connected to one end of the slide rod 212. The slide rod 212 is slidably connected to the frame 1 through the linear bearing 4, thereby guiding the movement direction of the inner wall pressing component 2 and preventing the deviation of the movement direction of the inner wall pressing component 2 from adversely affecting the recording of the difference between the emission point and the reflection point.

[0042] Continue as Figures 1 to 2As shown, the cylindrical central axis positioning device also includes a first push-pull clamp 5, which is mounted on the frame 1. The output shaft of the first push-pull clamp 5 is connected to the inner wall pressing component 2. The number of first push-pull clamps 5 is the same as the number of inner wall pressing components 2, and they are connected one-to-one. Therefore, when the central axis position of the cylindrical body 100 needs to be positioned, the operator can push and pull the first push-pull clamp 5 to make the inner wall pressing component 2 press against the inner wall 101 of the cylindrical body 100. During the rotation of the frame 1, this prevents the inner wall pressing component 2 from being subjected to a reaction force and retracting. After positioning the central axis position of the cylindrical body 100, the operator can pull back the first push-pull clamp 5 to move the inner wall pressing component 2 away from the inner wall 101 of the cylindrical body 100, increasing the operational convenience of the cylindrical central axis positioning device. It should be noted that the specific structure of the push-pull clamp is common knowledge that is known to those skilled in the art.

[0043] When using the cylindrical centerline positioning device to position the centerline of the cylindrical body 100, the first flange surface 102 is prone to wear because the frame 1 rests on and rotates on the first flange surface 102 of the cylindrical body 100. To solve the above technical problems, the following method is used... Figures 1 to 2 As shown, the cylindrical central axis positioning device also includes a first flange face pressing component 6. The first flange face pressing component 6 includes a second mounting frame 61 and a second rotating wheel 62. The second mounting frame 61 is mounted on the frame 1. The rotating shaft of the second rotating wheel 62 is rotatably connected to the second mounting frame 61. The wheel surface of the second rotating wheel 62 overlaps with the first flange face 102 to overlap the frame 1 with the first flange face 102, thereby reducing the friction between the frame 1 and the first flange face 102 of the cylindrical body 100 and preventing the first flange face 102 from wearing.

[0044] In this embodiment, the first flange face pressing assembly 6 includes at least two second rollers 62 spaced apart from each other. The two first flange face pressing assemblies 6 are symmetrically arranged along the central axis of the frame 1, thereby increasing the number of second rollers 62 to further reduce the friction between the frame 1 and the first flange face 102.

[0045] Continue as Figures 1 to 2 As shown, the cylindrical central axis positioning device also includes a third rotating wheel 7. The shaft of the third rotating wheel 7 is rotatably connected to the frame 1. When the frame 1 is engaged with the first flange surface 102, the wheel surface of the third rotating wheel 7 is engaged with the second flange surface 103. This allows the cylindrical central axis positioning device to simultaneously grip the cylindrical body 100 from both flange surfaces when positioning the central axis position of the cylindrical body 100, preventing the cylindrical central axis positioning device from sliding along the central axis direction of the cylindrical body 100 when positioning the central axis position of the cylindrical body 100.

[0046] Preferably, the cylindrical centerline positioning device further includes a second push-pull clamp 8, which is mounted on the frame 1. The output shaft of the second push-pull clamp 8 is connected to the shaft of the third rotating wheel 7. By pushing and pulling the second push-pull clamp 8, the third rotating wheel 7 can be adapted to cylindrical bodies 100 of different lengths and can clamp the cylindrical body 100 together with the second rotating wheel 62 from the two flange surfaces of the cylindrical body 100.

[0047] Continue as Figures 1 to 2 As shown, the total station reflector 3 includes a mirror body 31 and a rotating bearing 32. The outer ring of the rotating bearing 32 is mounted on the frame 1, and the mirror body 31 is mounted on the inner ring of the rotating bearing 32. Thus, when using the total station, the mirror body 31 can be pressed to prevent it from rotating with the frame 1 and to receive laser light, so that the staff can record the difference between the emission point and the reflection point.

[0048] Continue as Figures 1 to 2 As shown, two inner wall pressing components 2 form inner wall pressing groups. At least two groups of inner wall pressing groups are arranged circumferentially along the central axis of the frame 1, thereby increasing the stability of the frame 1 during rotation and preventing the change in the position of the central axis of the frame 1 during rotation from adversely affecting the central axis of the positioning cylinder 100. It should be noted that the number of inner wall pressing groups can be 1, 2, 3, 4, or even more. Those skilled in the art can reasonably set them according to actual needs, and will not be elaborated here.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
