Description
Technical Field
[0001] This utility model relates to the field of marine filter technology, specifically to an auxiliary device for positioning and installing aluminum alloy marine filter flanges. Background Technology
[0002] Currently, marine filter flanges are generally designed in a cylindrical shape, and the filter typically consists of a filter tube body and a flange connecting pipe. To reduce the impact of misalignment between the filter flange and its mating flange connection holes, the bolt holes connecting the filter flange are generally designed with an even number of holes, and the number of bolt holes is evenly distributed according to the flange size. Under normal circumstances, there is a vertical or horizontal relationship between the bolt holes, forming a standard flange bolt hole layout.
[0003] When installing aluminum alloy marine filter flanges, the center line of the filter opening is first drawn on the filter surface structure according to the filter manufacturing drawing. The flange connection pipe opening of the appropriate size is then made according to the dimensions on the drawing. Generally, the flange connection pipe and flange are pre-assembled. The flange connection pipe is connected to the saddle joint of the filter body. When installing the flange connection pipe, it is necessary to ensure that not only the flange face of the flange connection pipe is dimensionally aligned with the center line of the filter body pipe, but also that the flange face is parallel to the center line of the filter body, and that the bolt holes of the flange are horizontal. Typically, one person measures the dimensions to ensure the above technical requirements are met, while another person performs the welding fixation. The two people work together to complete the installation of the filter flange connection pipe.
[0004] Existing filter flange connection pipe installation methods suffer from drawbacks such as a small proportion of filters used in shipbuilding, yet a high proportion of personnel are required, resulting in wasted manpower; the installation process is cumbersome, requiring repeated adjustments, leading to low product precision and low construction efficiency. Therefore, there is an urgent need to develop a positioning and installation device that is simple in structure, versatile, easy to operate, and can effectively improve the installation accuracy of filter flanges. Utility Model Content
[0005] In view of at least one deficiency of the prior art, the purpose of this utility model is to provide an auxiliary tool for positioning and installing aluminum alloy marine filter flanges. It has a simple structure, good versatility, and is easy to operate, and can effectively improve the installation accuracy of filter flanges.
[0006] A positioning and installation auxiliary device for aluminum alloy marine filter flanges includes a fixing component and an adjusting plate. The fixing component includes a base and a support plate vertically disposed on the base, and there are at least two support plates. The adjusting plate is connected to the two support plates through a first oblong through hole provided on the at least two support plates. The positioning and installation of flanges of different sizes can be achieved by moving the adjusting plate on the first oblong through hole.
[0007] A further improvement is that the support plate is an L-shaped support plate; the support plate is provided with a first waist-shaped through hole perpendicular to the base.
[0008] A further improvement is that there are two support plates, which are disposed on the same side of the base. Each support plate has a first plate surface and a second plate surface that are perpendicular to each other. The first plate surfaces of the two support plates are parallel, and the second plate surfaces of the two support plates are parallel. The distance between the first plate surfaces of the two support plates is greater than the distance between the second plate surfaces of the two support plates. The first oblong through hole is disposed on the second plate surface of the two support plates.
[0009] A further improvement is that the adjusting plate is L-shaped; the adjusting plate has a vertical plate surface and a horizontal plate surface that are perpendicular to each other, and the vertical plate surface of the adjusting plate has through holes at both ends and a second oblong through hole in the middle. In this utility model, the flange is fixed to the second oblong through hole of the adjusting plate by using bolts or the like, thereby realizing the adjustment, positioning and installation of the flange during subsequent installation.
[0010] A further improvement lies in that the through holes on the vertical surface of the adjusting plate are adapted to the size of the first oblong through hole on the support plate, thereby enabling the adjusting plate to be fixed and moved on the two support plates. In this invention, the adjusting plate can move within the first oblong through hole on the two support plates according to the size of the flange, adjusting the flange installation height and ensuring accuracy during installation.
[0011] The adjustment plate described in this utility model can be installed on the side of the second plate of the support plate away from the base, or it can be installed on the side of the second plate of the support plate close to the base. It can be adjusted and selected according to the specific needs of the actual application.
[0012] A further improvement is that the spacing of the through holes on the vertical surface of the adjusting plate matches the spacing of the first oblong through holes on the two support plates. In this invention, the through holes on the vertical surface of the adjusting plate, which are matched in size to the first oblong through holes on the support plates, can be fixed using bolts or other parts. Simultaneously, the adjusting plate can move along the first oblong through holes to adjust its height, thereby adapting to different flange sizes and further improving the installation accuracy of the flange.
[0013] A further improvement is that the horizontal surface of the adjustment plate is arranged parallel to the base. In this invention, the horizontal surface of the adjustment plate is parallel to the base and is movably connected to the support plate at a 90° angle.
[0014] A further improvement is that a locking element is provided on the side of the base away from the support plate. This locking element secures the filter body to the base, facilitating flange positioning during installation and improving installation accuracy.
[0015] In this invention, when a locking element is provided on the base, the adjusting plate should be installed on the side of the support plate away from the base, thereby achieving the fixed installation of the filter flange and the filter body.
[0016] A further improvement is that the locking element includes a nut fixed to the base and a matching screw.
[0017] The locking component described in this invention can be a conventional bolt structure in the art, and the filter body can be locked and fixed by adjusting the bolt.
[0018] In this invention, conventional bolts and other structures can be used for fixing during the process of installing the flange on the vertical surface of the adjusting plate and installing the adjusting plate on the support plate.
[0019] In this invention, the support plate and adjustment plate are used to fix flanges of different sizes. At the same time, it ensures that during the welding process of the flange and the filter body, the flange face of the flange connecting pipe and the center line of the filter body pipe are consistent with the drawn drawings, the flange face is parallel to the center line of the filter body, and the screw holes are horizontal. This effectively improves the accuracy of flange installation, and the final installed filter flange positioning deviation can be kept within the range of less than 0.01mm.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The present invention has a simple structure, good stability, convenient and quick operation, and can be reused.
[0021] (2) This utility model can effectively improve the installation accuracy and efficiency of filter flange during use, with the filter flange positioning deviation being less than 0.01mm. At the same time, it can reduce personnel input and save costs.
[0022] (3) This utility model can be applied to the installation of all ship filter flanges and filter flanges of different sizes. Attached Figure Description
