Description

Technical Field

[0001] This utility model relates to the field of diesel engine pipeline technology, and in particular to a flange welding auxiliary positioning device for diesel generator set pipelines. Background Technology

[0002] Diesel generator sets are widely used in industrial production, construction, emergency power supply and other fields. The stability and sealing of diesel engine pipelines directly affect the working efficiency and safety of generator sets. Therefore, the welding quality of pipelines is crucial. However, traditional flange welding methods usually rely on manual positioning and fixing or the use of some simple clamps. These methods have problems such as inaccurate positioning or welding deformation, which affect the flange welding quality and production efficiency.

[0003] In the pipeline welding process of diesel generator sets, the welding position of flanges is often quite complex, and the welding process requires strict adherence to specifications. Due to the diversity of flange dimensions, shapes, and welding angles, workers often need to spend a significant amount of time manually adjusting and positioning them during welding, and even slight errors can lead to welding defects. Therefore, we propose an auxiliary positioning device for flange welding in diesel generator set pipelines to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary positioning device for flange welding of diesel generator set pipelines, so as to solve the problems of inaccurate positioning, welding deformation and low production efficiency caused by existing manual positioning welding of flanges.

[0011] Preferably, a scale is connected to the bottom of the column sleeve for fine adjustment of the angle of the flange positioning plate.

[0012] Preferably, the base includes adjusting screws at the four corners of its surface for positioning the device.

[0013] Compared with existing technologies, the flange welding auxiliary positioning device for diesel generator set pipelines of this utility model has the following advantages: This device separates the main shaft and the ball screw. The rotation of the flange positioning plate is adjusted by the nut handle, and the flange angle is precisely controlled by the dial. The ball screw raises and lowers the flange positioning plate by adjusting the handwheel. The two work together to accurately position the flange positioning plate. At the same time, the base can also move back and forth on the working surface. Finally, it is fixed to the working surface by adjusting screws.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0020] This utility model provides an auxiliary positioning device for flange welding of diesel generator set pipelines. Please refer to [link / reference]. Figures 1-2 The system includes a main structure 1, comprising a main shaft 101, a sleeve 102 surrounding the main shaft 101, a clamping block 103 disposed on the upper end of the main shaft 101, a tapered sleeve 104 surrounding the clamping block 103, a base 105 disposed at the bottom of the main shaft 101, a cap 106 disposed at the top of the main shaft 101, ball screws 107 disposed side-by-side and fixed on one side of the main shaft 101, and bushings 108 disposed at both ends of the main shaft; and an adjustment mechanism 2, comprising a sleeve 105 disposed on the cap 101. The components include: a cap handle 201 on one side of the 06; an adjusting handwheel 202 located at the top of the ball screw 107; a first locking handle 203 located on one side of the tapered sleeve 104; and a second locking handle 204 located on one side of the column sleeve 102; a flange positioning plate 3 for fixing and clamping the flange, which includes multiple mounting holes 301 on its surface; and a connector 4 for connecting the spindle 101, the ball screw 107, and the flange positioning plate 3.

[0021] The tapered sleeve 104 is simultaneously connected to the top of the ball screw 107 via a thrust ball bearing 109; the connecting member 4 includes a fixing nut 401 for connecting the flange positioning plate 3, and a screw nut 402 that cooperates with the ball screw 107; a scale 102a is externally connected to the bottom of the column sleeve 102 for finely adjusting the angle of the flange positioning plate 3; the base 105 includes adjusting screws 105a at the four corners of its surface for positioning the device.

[0022] It should be noted that the workbench and pipe support are also used in conjunction with this flange welding auxiliary positioning device. The workbench surface has multiple grooves for the sliding adjustment of the base 105. The pipe support is used to provide support for the pipe when aligning the pipe with the flange, which facilitates the welding of the flange and the pipe. When connecting pipe fittings with flanges at both ends, two sets of this device need to be used in pairs on the same workbench.

[0023] Preferably, the main shaft 101 is made of high-strength steel to ensure sufficient rigidity and stability during welding. The main shaft 101 is the core support component of this device. The sleeve 102 is fitted onto the outer wall of the main shaft, and the bushing 108 is fitted onto both ends to protect and reduce wear. The braking block 103 is located at the upper end of the main shaft 101 and is used to fix the tapered sleeve 104. The tapered sleeve 104 is connected to the top bearing of the ball screw 107 through the thrust ball bearing 108. The ball screw 107 can rotate around the main shaft 107 through the thrust ball bearing 108 to change the angle of the flange positioning plate. Its rotation is driven by the cap handle 201 to drive the cap 106 to drive the main shaft 101 to rotate. The inside of the tapered sleeve 104 is keyed to the main shaft 101 and will also rotate together. The rotation angle is observed through the dial 102a and adjusted to the corresponding angle before stopping. The second locking handle 204 is then locked.

[0024] Preferably, the base 105 is made of cast iron, which has good shock resistance and ensures that the device will not shift during the welding process. Four adjusting screws 105a are provided at the four corners of the base 105. The adjusting screws 105a are inserted into the positioning holes on the worktable for accurate positioning.

[0025] Better, such as Figure 1 As shown, the connector 4 is used to connect the main shaft 101, the ball screw 107, and the flange positioning plate 3. When adjusting the height, the manual adjustment handwheel 202 drives the ball screw 107 to rotate. When rotating, it cooperates with the screw nut 402 to raise and lower the connector 4. The flange positioning plate 3 is fixedly connected to the connector 4 by a T-shaped fixing nut, so it will synchronously drive the flange positioning plate 3 to adjust the height. The column sleeve 102 is also provided with a horizontal scale line for adjusting the height. After the height adjustment is completed, the first locking handle 203 is locked.

[0026] In summary, the flange welding auxiliary positioning device for diesel generator set pipelines of this utility model separates the main shaft and the ball screw. The rotation of the flange positioning plate is adjusted by the nut handle, and the flange angle is precisely controlled by the dial. The ball screw raises and lowers the flange positioning plate by adjusting the handwheel. The two work together to accurately position the flange positioning plate. At the same time, the base can also move back and forth on the working surface. Finally, it is fixed to the working surface by adjusting screws. This device is easy to adjust and can quickly adjust the flange position according to different types of pipe fittings, adapting to various welding needs. It not only improves the accuracy and efficiency of flange welding, but also significantly reduces the incidence of welding defects, and has broad application prospects.

[0027] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
