Description

Technical Field

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

[0002] Pipe flanges are connectors installed at the ends of pipes or at the inlet and outlet of equipment to enable detachable connections between pipes or between pipes and equipment (such as valves and pumps). During the manufacturing process of pipe flanges, the pipes and flanges need to be welded together.

[0003] Currently, the typical welding process involves the operator holding the pipe, aligning it with the connection hole on the flange, and then welding.

[0004] However, after welding, multiple angles of the pipe still need to be manually measured to ensure they meet the standards. If the angles are not up to standard, operators need to tap the pipe with a rubber mallet to correct them. Therefore, the current welding process cannot directly determine the pipe angles, leading to the need for secondary operations and further increasing the workload of the operators.

[0005] The content in the background section is merely technology known to the public and does not necessarily represent existing technology in this field. Utility Model Content

[0037] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, 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.

[0038] According to one aspect of this application, a pipe fixing device for a pipe flange is provided. Figure 1 A schematic diagram of the pipe fixing device according to an embodiment of this application is shown.

[0039] According to the example embodiment, such as Figure 1 As shown, the pipe fixing device includes a processing table 1, at least one positioning element 2, and at least one set of fixing mechanisms 3. The pipe flange is mounted on the processing table 1.

[0040] For example, the processing table 1 can be, but is not limited to, a circular or rectangular plate structure. The angle of the processing table 1 can be customized according to processing needs.

[0041] For example, the processing table 1 is a circular plate and is arranged horizontally. The pipe flange is placed on the upper surface of the processing table 1.

[0042] According to the example embodiment, such as Figure 1 As shown, at least one positioning element 2 is disposed on the processing table 1 and mates with the connection hole of the pipe flange to position the pipe flange.

[0043] For example, multiple positioning elements 2 can be configured, arranged in a circular array. The positioning elements 2 can be, but are not limited to, circular or rectangular columnar structures, and the specific configuration can be selected according to the shape of the connecting hole.

[0044] For example, such as Figure 1 As shown, there are 6 positioning elements 2 arranged in a circular array at the center of the machining table 1. The positioning elements 2 have a circular cylindrical structure and are arranged perpendicular to the surface of the machining table 1.

[0045] According to the example embodiment, such as Figure 1 As shown, at least one set of fixing mechanisms 3 is set on the processing table 1 and is set in correspondence with the positioning component 2.

[0046] For example, the fixing mechanism 3 can be configured as multiple sets, arranged in a circular array. The fixing mechanism 3 is configured in correspondence with the positioning element 2, that is, one positioning element 2 corresponds to one set of fixing mechanism 3.

[0047] The fixing mechanism 3 is located on the side of the positioning component 2 away from the central axis of the processing table 1.

[0048] For example, such as Figure 1 As shown, the fixing mechanism 3 is configured in 6 groups, and the 6 groups of fixing mechanisms 3 are arranged in a circular array. The radius formed by the circular array of the 6 groups of fixing mechanisms 3 is larger than the radius formed by the circular array of the 6 positioning elements 2.

[0049] According to the example embodiment, such as Figure 1 As shown, one end of the pipe to be processed contacts the positioning element 2 through the connection hole of the pipe flange to limit the height position of the pipe within the connection hole. The other end of the pipe to be processed is detachably connected to the fixing mechanism 3 to fix the pipe to be processed onto the pipe flange.

[0050] For example, the pipe to be processed can be a straight pipe or a bent pipe, and the specific settings can be customized according to processing needs. The detachable connection method between the pipe to be processed and the fixing mechanism 3 can be, but is not limited to, snap-fit ​​or threaded connection.

[0051] For example, the pipe to be processed is a bent pipe, with one end bent. The bent end of the pipe is inserted into the connecting hole and abuts against the top of the positioning member 2 to limit the height position of the pipe within the connecting hole. The straight end of the pipe is engaged with the fixing mechanism 3.

[0052] Through the above embodiments, this application can determine the position of the pipe flange using a positioning element and accurately position the angle of the pipe to be processed using a fixing mechanism. This application enables the pipe to be processed to maintain the correct angle during processing and fixing, thereby improving processing accuracy and reducing the labor intensity of operators.

[0053] Figure 2 A cross-sectional schematic diagram of a support member according to an embodiment of this application is shown.

[0054] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the fixing mechanism includes a support member 31 and a fixing assembly 32. The support member 31 is mounted on the processing table 1, and a guide hole 311 is provided on the support member 31.

[0055] For example, the support member 31 may be, but is not limited to, a circular or rectangular columnar structure. The guide hole 311 may be located at the top of the support member 31 or in the middle of the support member 31. The angle between the axial direction of the guide hole 311 and the surface of the machining table 1 is less than 90°.

[0056] For example, the support member 31 is a rectangular column and is vertically arranged, with an inclined surface at its top. A guide hole 311 is provided at the top of the support member 31, and the angle between the axis of the guide hole 311 and the surface of the processing table 1 is 45°.

[0057] According to the example embodiment, such as Figure 1 As shown, one end of the fixing component 32 is detachably connected to the support component 31 through the guide hole 311, and the other end is detachably connected to the other end of the pipe to be processed.

[0058] For example, the detachable connection between the fixing component 32 and the support 31 can be, but is not limited to, a snap-fit ​​or threaded connection. The detachable connection between the fixing component 32 and the pipe to be processed can be, but is not limited to, a snap-fit ​​or plug-in connection.

[0059] Through the above embodiments, this application can adjust the angle of the fixing component by the support member, so that the fixing component can be aligned with the pipe to be processed, thereby improving the angle accuracy of the pipe to be processed and thus improving the processing precision.

[0060] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the fixing assembly 32 includes a fastener 321, a connecting rod 322, and a fixing member 323. The connecting rod 322 is slidably connected to the support member 31 through a guide hole 311, and the sliding direction of the connecting rod 322 is parallel to the axial direction of the pipe to be processed. The fixing member 323 is fixedly disposed on the end of the connecting rod 322 away from the support member 31, and the fixing member 323 is connected to the other end of the pipe to be processed through the fastener 321.

[0061] For example, fastener 321 may include, but is not limited to, clamps or clamping mechanisms. The clamping mechanism may consist of a pair of U-shaped plates and bolts. Connecting rod 322 may be a rectangular rod structure or a circular rod structure. Fixing member 323 may be a plate structure or a block structure; the specific shape of fixing member 323 can be selected according to processing requirements.

[0062] For example, fastener 321 is a clamp. Connecting rod 322 passes through guide hole 311 and is slidably connected to support member 31. Fixing member 323 is a circular plate structure and abuts tightly against the other end of the pipe to be processed. Clamp is engaged at the connection between fixing member 323 and pipe to be processed to securely fix the pipe to be processed.

[0063] Through the above embodiments, this application can limit the movement direction of the connecting rod through the guide hole, and this application can also limit the angle of the pipe to be processed through the fastener, so that the fixing part is not easy to deviate, thereby making it easier to improve the processing accuracy of the pipe to be processed.

[0064] According to the example embodiment, the diameter of the fastener 323 matches the diameter of the pipe port to be processed.

[0065] For example, the fastener 323 is a circular plate structure, the pipe port to be processed is circular, and the diameter of the fastener 323 is equal to the diameter of the pipe port to be processed.

[0066] Through the above embodiments, this application can limit the diameter of the fixing member and the diameter of the pipe port to be processed, so that the fastener can clamp the fixing member and the pipe port to be processed, thereby making the pipe to be processed less prone to shaking, and thus making it easier to improve the processing accuracy of the pipe to be processed.

[0067] According to the example embodiment, such as Figure 1 As shown, at least one tool groove 11 is provided on the machining table 1.

[0068] For example, multiple cutter grooves 11 can be provided, and the cutter grooves 11 are located between the support member and the positioning member. The cutter grooves 11 cooperate with the positioning member to determine the position of the pipe flange to be processed.

[0069] For example, there are 4 cutting grooves 11, which are arranged symmetrically at the center.

[0070] Through the above embodiments, this application can use the tool groove and positioning element to ensure that the pipe flange to be processed can only be placed in a fixed position, making it easy for operators to confirm the position of the pipe flange to be processed, thereby improving the processing accuracy of the pipe flange to be processed.

[0071] According to the example embodiment, such as Figure 1 As shown, the fixing mechanism also includes an anti-detachment component 33, which is disposed at the other end of the connecting rod 322 in correspondence with the fixing component 323.

[0072] For example, the anti-slip component 33 can be a circular block structure or a rectangular block structure, and the specific configuration can be selected according to processing requirements. The anti-slip component 33 can abut against the inclined surface on the support component 31 to prevent the connecting rod 322 from slipping. The anti-slip component 33 and the connecting rod 322 can be fixedly connected or detachably connected. The fixed connection method can be, but is not limited to, welding or bonding. The detachable connection method can be, but is not limited to, snap-fit ​​or threaded connection.

[0073] For example, the anti-detachment component 33 is a circular block structure, and the anti-detachment component 33 and the connecting rod 322 are welded together.

[0074] Through the above embodiments, this application can limit the maximum movable distance of the connecting rod by using the anti-detachment component, which can easily ensure the distance between the fixing component and the port of the pipe to be processed, thereby easily improving the processing accuracy of the pipe to be processed.

[0075] Figure 3 A schematic diagram of the structure of the fixing component according to an embodiment of this application is shown; Figure 4 A schematic diagram of the structure of the limiting member according to an embodiment of this application is shown; Figure 5 A cross-sectional schematic diagram of the limiting member according to an embodiment of this application is shown.

[0076] According to the example embodiment, such as Figure 2 and Figure 3 As shown, the support member 31 is provided with a passage part 312, the connecting rod 322 is provided with a groove 3221, and the fixing mechanism 3 also includes a limiting member. When the connecting rod 322 slides to the target position, the limiting member cooperates with the groove 3221 through the passage part 312 to limit the position of the connecting rod 322.

[0077] For example, the via 312 is located at the position of the hole wall of the guide hole 311. It should be noted that the target position refers to the position where, with the anti-detachment member 33 abutting against the inclined surface, the connecting rod 322 moves to its maximum distance so that the fixing member 323 fits against the port of the pipe to be processed.

[0078] Through the above embodiments, this application can prevent the connecting rod from moving axially by using a limiting member to cooperate with the groove, thereby further improving the processing accuracy of the pipe to be processed.

[0079] Optionally, according to the example embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, part 312 is a threaded through hole, and the limiting member is set screw 34a.

[0080] For example, the threaded through hole is connected to the guide hole 311, and the set screw 34a is threadedly connected to the threaded through hole. When one end of the set screw 34a is screwed into the guide hole 311 from the threaded through hole, one end of the set screw 34a is inserted into the groove 3221.

[0081] Through the above embodiments, this application can prevent the connecting rod from moving axially by tightly fitting the set screw and the threaded through hole, thereby further improving the processing accuracy of the pipe to be processed.

[0082] Optionally, according to the example embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, part 312 is a smooth through hole, and the limiting member is a spring pin 34b.

[0083] For example, the spring pin 34b includes a connecting pin and a spring, the connecting pin being slidably connected within a smooth through hole. One end of the spring is fixedly connected to the inner wall of the smooth through hole, and the other end is fixedly connected to the connecting pin.

[0084] Through the above embodiments, this application can use the spring pin and smooth through hole to facilitate fixing and unlocking the connecting rod, prevent the connecting rod from moving axially, and thus further improve the processing accuracy of the pipe to be processed.

[0085] Optionally, such as Figure 1 As shown, fastener 321 is a clamp.

[0086] Through the above embodiments, this application can use clamps to connect the pipe to be processed without welding the fastener to the pipe, and only simple tools are needed to complete the connection, thereby improving the processing efficiency of the pipe.

[0087] 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.
