DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0024] In the description of the embodiments of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected or integrally connected, it can be mechanically connected, or it can be electrically connected or directly connected, or it can be indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meaning of the above-mentioned term in the present application can be understood according to the specific circumstances.

[0025] As used throughout, the terms "bottom," "top," "on," and the like, refer to a relative position of components of the device with respect to one another, and are not necessarily limited to the actual orientation of the components in space.

[0026] For the purpose of understanding the embodiments of the present application, further explanation will be given below in conjunction with the accompanying drawings with specific embodiments, which do not constitute limitation to the embodiments of the present application.

[0027] In the field of aerospace, pipes are usually used to transport various fluids, such as fuel, coolant, etc. In order to ensure the safe operation of spacecraft, etc., the forming quality of the pipe, such as the forming precision of the pipe, the sealing effect of the welding, etc., has high requirements. In some cases, the pipe fittings to be connected not only have differences in shape, but even the types of pipe fittings are completely different. For example, in some pipes, part of the pipe body needs to use corrugated pipes, and another part needs to use ordinary pipe fittings. For example, in some pipes, the pipe fittings at different positions of the pipe body have great differences in direction and shape. However, in order to ensure the processing quality of the pipe, these pipe fittings need to be accurately aligned and well welded. Therefore, high requirements are put forward for the positioning of the pipe.

[0028] Therefore, as shown in Figure 1 the present specific embodiment provides a pipe positioning device. The pipe positioning device comprises a bottom plate 1 and a support plate 2.

[0029] The bottom plate 1 is arranged along a substantially horizontal direction to support other components and pipe fittings of the pipe positioning device from below. The support plate 2 is connected with the bottom plate and extends upward along a direction intersecting with the bottom plate to support pipe fittings forming the pipe 3 and structures related thereto in another direction.

[0030] The support plate 2 can be fixedly arranged on the bottom plate 1, and more preferably, the support plate and the bottom plate are connected in a detachable manner, such as threaded connection, clamping, etc. In this way, the position of the support plate can be adjusted as needed, and the support plate with a suitable shape can be replaced to meet the needs of different pipe production.

[0031] The bottom plate 1 provides a stable base as a whole. In order to facilitate operation, the bottom plate can be various flat shapes suitable for operation, for example Figure 1 As shown, the bottom plate can be formed to have a first surface extending along a first direction and a second surface extending along a second direction, so that the operator can complete the processing of the pipe fittings of each part of the pipe in front of the bottom plate.

[0032] The shape of the support plate 2 is set according to the shape of the pipeline. In order to facilitate welding and positioning operations and reduce weight to a certain extent, at least one window can be provided on the support plate 2. Operators can observe and adjust the status of the pipes through the window, and can also perform operations such as welding at the connection between pipes through the window.

[0033] The base plate 1 is also provided with a first radial positioning bracket 7, which includes a first support 7-1 and a positioning pin 7-2, such as... Figure 3 As shown, the first support is disposed on the upper surface of the base plate 1. Preferably, the first support is detachably connected to the base plate. The first support 7-1 is used to support the first radial positioning bracket 7 and can be disposed as needed in a location in the pipeline that is prone to shaking or stress concentration, for example, Figure 1 The bends or both ends of the corrugated pipe shown are positioned to effectively prevent pipe swaying, thus achieving pipe positioning on the horizontal plane. The positioning pins 7-2 are located on the upper surface of the first support, securing the pipe fittings from both sides to prevent swaying.

[0034] In this specific embodiment, there can be multiple first radial positioning brackets 7, based on the principle of holding the pipeline in the necessary positions to prevent it from shaking. Furthermore, the first radial positioning brackets can be detachably mounted on the base plate 1, so that the first radial positioning brackets are set at different positions according to different pipeline characteristics to achieve the fixation of the pipeline on the horizontal plane.

[0035] In this specific embodiment, the pipeline may include a bellows 5, which typically has continuous corrugated protrusions. When the bellows contacts the locking pin, deformation may occur due to the small contact area of ​​the pin. Therefore, as... Figure 1 As shown, in this specific embodiment, the corrugated pipe is held by the second radial positioning bracket 9, achieving positioning on the horizontal plane. The second radial positioning bracket 9 is disposed on the pipe positioning device, and the second radial positioning bracket includes a second support 9-1 and a locking block 9-2, as shown... Figure 4 As shown. The second support 9-1 is detachably connected to the base plate 1. The second support 9-1 is used to support the components of the second radial positioning bracket 9. The second support is provided with the bracket 9-2. The middle part of the bracket is a flat surface with an inner wall in the shape of a "V", which facilitates the placement of the corrugated pipe 5 without damaging the shape of the corrugated pipe surface.

[0036] The first radial positioning bracket 7 and the second radial positioning bracket 9 position the pipe in the horizontal direction, avoiding the movement of each component of the pipe or the whole pipe in the horizontal direction to affect the quality of welding. However, for the pipe with three-dimensional space shape, stable positioning in the vertical direction is also needed to avoid the movement in the vertical direction. At the same time, the positioning should not interfere with the welding operation of the pipe to facilitate the welding operation after positioning.

[0037] Therefore, further, the pipe positioning device further comprises a first end positioning assembly 4, the number of the first end positioning assembly can be multiple, that is, corresponding to the number of the end openings of the pipe, when a pipe has two openings, one end positioning assembly can be arranged at the position corresponding to each of the two openings, and when the pipe has multiple openings, the positioning assembly corresponding to each end can be arranged at the position corresponding to each end.

[0038] As shown in Figures 1-2 The first end positioning assembly 4 comprises a support 4-1, a positioning flange 4-2, a positioning core 4-3 and a sliding block 4-4.

[0039] As shown in Figure 2 The support 4-1 is arranged on the first surface of the bottom plate 1 in the direction intersecting with the bottom plate, the bottom surface of the support 4-1 is provided with the sliding block 4-4, and the bottom plate 1 is provided with a sliding groove 1-1, and the sliding block cooperates with the sliding groove to enable the first end positioning assembly 4 to move only in the horizontal direction. By thus arranging, the position of the first end positioning assembly on the bottom plate can be flexibly adjusted according to the size of the pipe to be positioned, so that the pipe positioning device has greater operation space when positioning the pipe placed in the horizontal direction, and the movement of the pipe in the horizontal direction in other directions except the preset direction is limited.

[0040] The positioning flange 4-2 is arranged on the support 4-1, and the positioning core 4-3 is fixedly connected to the support 4-1 at the position corresponding to the opening of the pipe. The outer diameter of the positioning core 4-3 is adapted to the inner diameter of the pipe to be positioned.

[0041] The positioning flange 4-2 is arranged on the support 4-1, and the positioning core 4-3 is fixedly connected to the support 4-1 at the position corresponding to the opening of the pipe. The outer diameter of the positioning core 4-3 is adapted to the inner diameter of the pipe to be positioned, so that the pipe can be sleeved on the positioning core. When the pipe is sleeved on the positioning core, the pipe and the positioning core are coaxially arranged, and then the flange of the pipe is threadedly connected with the positioning flange 4-2, so as to fasten the pipe and the first end positioning assembly together.

[0042] In addition, the sliding block 4-4 can also be arranged on the bottom plate 1, and the sliding groove is arranged on the bottom surface of the support 4-1.

[0043] Further, an operation portion 4-5 is arranged on the support of the first end positioning assembly 4 and the second end positioning assembly 6, which is preferably arranged in the direction away from the positioning core of the first end positioning assembly 4 and the second end positioning assembly 6, so that a force can be applied on the operation portion 4-5 to drive the first end positioning assembly 4 to move in the horizontal direction and drive the second end positioning assembly 6 to move in the vertical direction.

[0044] In the specific embodiment, the pipeline has two openings, the first end positioning assembly 4 is arranged at the position corresponding to the first opening, and the second end positioning assembly 6 is arranged at the position corresponding to the second opening. The structure of the second end positioning assembly 6 is the same as that of the first end positioning assembly 4. The second end positioning assembly is arranged on the support plate 2, and the support plate 2 is provided with a sliding groove extending in the vertical direction, and the sliding block in the second end positioning assembly cooperates with the sliding groove to enable the second end positioning assembly 6 to move only in the vertical direction. By such arrangement, the position of the second end positioning assembly on the support plate 2 can be flexibly adjusted according to the size of the pipeline in the three-dimensional space, which provides a larger operation space for positioning operation and limits the movement of the pipe in other directions except the extension direction of the sliding groove in the vertical direction, which is beneficial to the longitudinal positioning of the longitudinally placed pipe in the pipeline in the three-dimensional space.

[0045] When positioning the pipeline in the three-dimensional space, the height of the second end positioning assembly 6 in the vertical direction is higher than that of the first end positioning assembly 4, that is, the first end positioning assembly 4 is arranged on the bottom plate 1, and the second end positioning assembly 6 is arranged on the support plate 2 which is away from the bottom plate 1 in the vertical direction. Since the second end positioning assembly 6 exerts a downward pressure on the pipe at the second opening of the pipeline under the action of gravity, the pipe is not easy to rotate relative to the positioning core, and the pipe can better avoid the shaking of the pipeline in the vertical direction under the action of the pressure, which is beneficial to the close butt joint of the longitudinally placed pipe and other pipes.

[0046] In the specific embodiment, the second end positioning assembly 6 preferably has an included angle with the bottom plate 1, that is, the support in the second end positioning assembly is arranged to be inclined to the bottom plate 1, so as to be suitable for the pipeline in the three-dimensional space.

[0047] Further, the bottom plate 1 and the support plate 2 are provided with stoppers 8, the stoppers 8 on the bottom plate abut against the corresponding positions of the support 4-1 along the horizontal direction, and the stoppers 8 on the support plate abut against the corresponding positions of the support along the longitudinal direction.

[0048] In the operation of the pipe positioning device, first, the bellows 5 are placed on the second radial positioning seats 9, then an acting force is applied on the operation part 4-5 to move the first end positioning assembly 4 along the horizontal direction and move the second end positioning assembly 6 along the longitudinal direction, so as to provide a larger operation space for the positioning of the pipe. Then, the ordinary pipes are fixed on the first radial positioning seats 7 at the positions of the two ends of the bellows, then the flanges at the two ends of the ordinary pipes are respectively sleeved on the positioning cores of the first end positioning assembly 4 and the second end positioning assembly 6, and then the flanges at the two ends of the ordinary pipes are respectively connected with the fixed flange screws of the first end positioning assembly and the second end positioning assembly.

[0049] The above detailed description is further detailed for the purpose, technical scheme and beneficial effects of the present application, and it should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
