Description

Technical Field

[0001] This application relates to the technical field of flange welding, and more specifically, to a fixing device for flange pipe welding. Background Technology

[0002] In the semiconductor industry, flanges and pipe fittings are used in exhaust gas treatment equipment. The welding of flanges and fittings involves securing the flanges. Current welding methods typically involve manually clamping the flanges with tools such as clamping pliers before performing precise welding.

[0003] The inventors of this application discovered that in the aforementioned method of manually clamping flanges using tools such as clamping pliers, the clamping force of the clamping pliers causes flange deformation. Furthermore, this clamping method does not limit flange deformation caused by high temperatures, leading to further deformation due to the high temperatures generated during welding. This results in the final deformation amount of the flange failing to meet user requirements and a low pass rate for finished flange fittings. In addition, substandard finished flange fittings can lead to poor airtightness in exhaust gas treatment equipment assembled with these substandard fittings, further affecting the performance of the exhaust gas treatment equipment.

The described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] According to one aspect of this application, a fixing device for welding flanged pipes is provided. Figure 1 A schematic diagram of the fixing device structure according to an embodiment of this application is shown.

[0032] According to the example embodiment, such as Figure 1 As shown, the fixing device 1 includes a base 11, a first fixing mechanism 12, and a second fixing mechanism 13.

[0033] For example, flange 2 and pipe 3 can be pre-tack welded together. Electric welding can be used to initially fix flange 2 and pipe 3. For example, a first fixing mechanism 12 and a second fixing mechanism 13 are used to fix flange 2. The first fixing mechanism 12 and the second fixing mechanism 13 can be located at both ends of the base 11.

[0034] For example, the base 11 can be a metal plate made of metal. For example, the shape of the base 11 can be rectangular.

[0035] like Figure 1 As shown, the first fixing mechanism 12 includes a first support member 121, a first fixing member 122, and a first driving member 123. The first support member 121 is disposed on one side of the base 11. The first fixing member 122 is slidably disposed on the first support member 121 and is used to clamp one side of the flange 2. The first driving member 123 is disposed on the first support member 121 and is drivenly connected to the first fixing member 122 to drive the first fixing member 122 to slide on the first support member 121.

[0036] For example, the first support member 121 can be a metal structure used to support the first fixing member 122.

[0037] For example, the first support member 121 can be made of metal such as iron, aluminum or aluminum alloy. For example, the top of the first support member 121 can be a plate-like structure, and the first fixing member 122 is slidably disposed on the plate-like structure at the top of the first support member 121.

[0038] For example, a sliding component can be provided on the top of the first support member 121, and the first fixing member 122 is slidably disposed on the first support member 121 through the sliding component.

[0039] For example, the first drive element 123 can be a displacement adjustment device with telescopic function.

[0040] For example, the first driving member 123 can be an electric cylinder, pneumatic cylinder or electric push rod with driving function, which can drive the first fixing member 122 to slide on the first support member 121.

[0041] The second fixing mechanism 13 is disposed on the other side of the base 11, opposite to the first fixing mechanism 12. The second fixing mechanism 13 includes a second support member 131, a second fixing member 132, and a second driving member 133. The second support member 131 is disposed on the other side of the base 11. The second fixing member 132 is slidably disposed on the second support member 131 and is used to clamp the other side of the flange 2. The second driving member 133 is disposed on the second support member 131 and is drivenly connected to the second fixing member 132 to drive the second fixing member 132 to slide on the second support member 131.

[0042] For example, the second support 131 can be a metal structure used to support the second fastener 132.

[0043] For example, the second support member 131 can be made of metal such as iron, aluminum, or aluminum alloy. For example, the top of the second support member 131 can be a plate-like structure, and the second fixing member 132 is slidably disposed on the plate-like structure at the top of the second support member 131.

[0044] For example, a sliding component may be provided on the top of the second support member 131, and the second fixing member 132 is slidably disposed on the second support member 131 through the sliding component.

[0045] For example, the second driving member 133 can be a displacement adjustment device with a telescopic function. Exemplarily, the second driving member 133 can be an electric cylinder, pneumatic cylinder, or electric push rod with a driving function, which can drive the second fixing member 132 to slide on the second support member 131.

[0046] The first driving member 123 drives the first fixing member 122 to move according to the first displacement control command sent by the external control mechanism, and the second driving member 133 drives the second fixing member 132 to move according to the second displacement control command sent by the external control mechanism, so that the first fixing member 122 and the second fixing member 132 cooperate with each other to fix the flange 2 from both sides.

[0047] For example, an external control mechanism (not shown in the figure) can be a control device that can issue movement control commands.

[0048] For example, the external control mechanism can be a controller (such as a cylinder controller or an electric cylinder controller). Both the first displacement control command and the second displacement control command can be commands that control the movement of the first fixed member 122 or the second fixed member 132 to generate displacement.

[0049] Through the above embodiments, this application secures the flange by providing two flange-clamping fixing mechanisms on both sides of the flange. The clamping force on the flange provides support from the outside for the flange to be welded, thereby reducing the deformation of the flange during high-temperature welding of the flange and pipeline. Furthermore, this application reduces human intervention during the fixing process of the flange to be welded, thus lowering labor costs. The process of fixing the flange to be welded by controlling the fixing mechanism with control signals is time-efficient, thereby improving welding efficiency.

[0050] According to an example embodiment, the first support member 121 includes a first side plate 1211, a second side plate 1212, a first top plate 1213, and two first guide rails 1214. The first side plate 1211 is disposed on one side of the first support member 121. The second side plate 1212 is disposed opposite to the first side plate 1211 on the other side of the first support member 121. The first top plate 1213 is disposed on top of the first side plate 1211 and the second side plate 1212. The two first guide rails 1214 are disposed opposite to each other on both sides of the top plate.

[0051] For example, the first side plate 1211, the second side plate 1212, and the first top plate 1213 can all be rectangular plates. The first side plate 1211 and the second side plate 1212 can be the same size. The two ends of the first top plate 1213 can be connected to the tops of the first side plate 1211 and the second side plate 1212, respectively. The connection between the first top plate 1213 and the first side plate 1211 and the second side plate 1212 can be a fixed connection or a detachable connection.

[0052] For example, the fixed connection method can be welding. The detachable connection method can be a snap-fit ​​connection.

[0053] Through the above embodiments, this application ensures the structural strength of the first support member through two side plates and a top plate, and realizes the sliding setting of the first fixing member through two guide rails set on the top plate.

[0054] According to an example embodiment, the second support member 131 includes a third side plate 1311, a fourth side plate (not shown), a second top plate 1312, and two second guide rails 1313. The third side plate 1311 is disposed on one side of the second support member 131. The fourth side plate is disposed opposite to the third side plate 1311 on the other side of the second support member 131. The second top plate 1312 is disposed on top of the third side plate 1311 and the fourth side plate. The two second guide rails 1313 are disposed opposite to each other on both sides of the top plate.

[0055] For example, the third side plate 1311, the fourth side plate, and the second top plate 1312 can all be rectangular plates. The third side plate 1311 and the fourth side plate can be the same size. The two ends of the second top plate 1312 can be connected to the tops of the third side plate 1311 and the fourth side plate, respectively. The connection between the second top plate 1312 and the third side plate 1311 and the fourth side plate can be a fixed connection or a detachable connection.

[0056] For example, the fixed connection method can be welding. The detachable connection method can be a snap-fit ​​connection.

[0057] Through the above embodiments, this application ensures the structural strength of the second support member through two side plates and a top plate, and realizes the sliding setting of the second fixing member through two guide rails set on the top plate.

[0058] According to an example embodiment, the first fixing member 122 includes a first slider 1221, a first connecting plate 1222, a first fixing plate 1223, and a first connecting member 1224. The first slider 1221 is slidably disposed on the first guide rail 1214. The first connecting plate 1222 is disposed on the first slider 1221. The first fixing plate 1223 is disposed on the first connecting plate 1222 and connects to the first slider 1221 through the first connecting plate 1222. One end of the first connecting member 1224 is connected to the first connecting plate 1222, and the other end is drivenly connected to the first driving member 123.

[0059] For example, there can be two first sliders 1221. Each first slider 1221 can be a metal structure with a groove that matches the shape of the first guide rail 1214. For example, the first connecting plate 1222 can be a rectangular metal plate, with two first sliders 1221 connected to its two ends respectively.

[0060] For example, the first connector 1224 may be an L-shaped metal connector.

[0061] Through the above embodiments, this application achieves the sliding configuration of the first fixed plate on the first guide rail by setting a first connecting plate, a first slider, and a first connecting member.

[0062] According to an example embodiment, the second fixing member 132 includes a second slider 1321, a second connecting plate 1322, a second fixing plate 1323, and a second connecting member 1324. The second slider 1321 is slidably disposed on the second guide rail 1313. The second connecting plate 1322 is disposed on the second slider 1321. The second fixing plate 1323 is disposed on the second connecting plate 1322 and connects to the second slider 1321 through the second connecting plate 1322. One end of the second connecting member 1324 is connected to the second connecting plate 1322, and the other end is drivenly connected to the second driving member 133.

[0063] For example, there can be two second sliders 1321, and each second slider 1321 can be a metal structure with a groove that matches the shape of the second guide rail 1313. For example, the second connecting plate 1322 can be a rectangular metal plate, with two second sliders 1321 connected to each end of the second connecting plate 1322.

[0064] For example, the second connector 1324 may be an L-shaped metal connector.

[0065] Through the above embodiments, this application achieves the slidable setting of the second fixing plate on the second guide rail by setting the second connecting plate, the second slider and the second connecting member.

[0066] Figure 2 A schematic diagram of the cooling mechanism according to an embodiment of this application is shown. According to an example embodiment, such as… Figure 2 As shown, the fixing device 1 also includes a cooling mechanism 14. The cooling mechanism 14 includes a third driving member 141 and a cooling plate 142. The third driving member 141 is located at the center of the base 11 and within the cavity formed between the first fixing mechanism 12 and the second fixing mechanism 13. The cooling plate 142 is driven to connect with the third driving member 141 and is used to support the flange 2. The third driving member 141 drives the cooling plate 142 to move vertically to a preset height position according to a third displacement control command sent by an external control mechanism.

[0067] For example, the third drive element 141 can be a displacement adjustment device with telescopic function.

[0068] For example, the third driving member 141 can be an electric cylinder, pneumatic cylinder or electric push rod with driving function, which can drive the cooling plate 142 to move in the vertical direction.

[0069] For example, the preset height position can be set by the user according to their needs, so that the first fixing plate 1223 and the second fixing plate 1323 can fix the flange 2 from both sides.

[0070] For example, the preset height position can be a height position that is flush with the bottom of the first fixing plate 1223 and the second fixing plate 1323.

[0071] For example, the third displacement control command can be a command that controls the movement of the cooling plate 142 to generate displacement.

[0072] Through the above embodiments, this application provides a cooling mechanism to cool the flange during the welding process, thereby reducing the temperature of the welded flange and reducing the possibility of flange deformation due to high temperature.

[0073] According to the example embodiment, the cooling plate 142 is a circular cooling plate 142. The flange 2 is a circular flange 2. One end of the first fixing plate 1223 is a first arc-shaped end (not shown in the figure). One end of the second fixing plate 1323 is a second arc-shaped end (not shown in the figure). The size of the cooling plate 142 matches the size of the flange 2. The first arc-shaped end and the second arc-shaped end are fitted against both sides of the flange 2 to fix the flange 2.

[0074] Through the above embodiments, this application improves the fit between the first and second fixing plates and the two sides of the circular flange by setting one end of the first fixing plate and one end of the second fixing plate to be arc-shaped, thereby improving the support of the circular flange and reducing the probability of flange deformation during welding.

[0075] According to an example embodiment, the cooling plate 142 includes a coolant passage 1421, a coolant inlet 1422, and a coolant outlet 1423. The coolant passage 1421 allows external coolant to pass through. The coolant inlet 1422 is connected to one end of the coolant passage. The coolant outlet 1423 is connected to the other end of the coolant passage.

[0076] For example, the coolant channels can be arranged in the shape of grille strips.

[0077] Through the above embodiments, by setting the shape of the coolant channel to a grid strip shape, the flow area of ​​the coolant is increased, the contact area between the cooling channel and the flange is improved, and thus the cooling effect is improved.

[0078] According to the example embodiment, the base 11, the first fixing member 122, the second fixing member 132, the first support member 121 and the second support member 131 are all provided with weight reduction holes 15.

[0079] For example, the shape of the weight reduction hole 15 is freely set by the user and is not limited here.

[0080] Through the above embodiments, this application reduces the weight of the fixing device by setting weight-reducing holes, reduces the material consumption for processing the fixing device, and thus reduces the processing cost of the fixing device.

[0081] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
