[0021] It should be noted that in this application, "multiple" includes two or more.
[0022] Please see Figure 1 and Figure 2 This application provides an auxiliary tooling for processing a cover assembly, which includes a cover 100 and a main body 200. The cover 100 and the main body 200 are welded together by an annular lip 300. The auxiliary tooling includes a fixed frame 11, a rotating frame 12, a sliding assembly 13, and a tool head 14. The rotating frame 12 is disposed on the fixed frame 11 and can rotate circumferentially relative to the fixed frame 11. The sliding assembly 13 is disposed on the rotating frame 12. The tool head 14 is disposed on the sliding assembly 13 and can drive the tool head 14 to move radially and axially. The tool head 14 is used to cut the weld of the annular lip 300 and / or weld the annular lip 300.
[0023] The annular lip 300 is roughly circular. The cover 100 and the main body 200 are two structural components manufactured separately. At least one of the cover 100 and the main body 200 forms the annular lip 300. The outer circumference of the annular lip 300 is continuously welded so that the cover 100 and the main body 200 can achieve a sealed connection.
[0024] Both the cover 100 and the main body 200 can be made of metal, such as stainless steel.
[0025] In some embodiments, the cover 100 may form an annular lip 300 that protrudes from the substrate of the cover 100 and may be welded to the body 200 to achieve a sealed connection between the cover 100 and the body 200.
[0026] In some embodiments, the body 200 may form an annular lip 300 that protrudes from the substrate of the body 200 and may be welded to the cover 100 to achieve a sealed connection between the cover 100 and the body 200.
[0027] In some embodiments, both the body 200 and the cover 100 can form annular lips 300, and the two annular lips 300 can be welded to achieve a sealed connection between the cover 100 and the body 200.
[0028] The cover assembly may be part of a generally cylindrical reactor. In some embodiments, the reactor includes a cover assembly, a body 200 forming an installation port and a reaction chamber, the installation port communicating with the reaction chamber, and a cover 100 closing the installation port.
[0029] In some embodiments, the cover 100 can be a flange cover, that is, the cover 100 can also be connected to the body 200 by bolts.
[0030] Please see Figure 2 , Figure 2 The black portion of the annular lip 300 is the weld seam. The tool head 14 is used to cut the weld seam of the annular lip 300 and / or weld the annular lip 300. In other words, the tool head 14 can provide at least one function of cutting the weld seam and welding.
[0031] In related technologies, reactors in chemical, nuclear power, and other fields typically have a long design life, such as around 8 years, and require annual maintenance. Each maintenance requires disassembling the weld seams of the annular lip. Manual welding and disassembly of the annular lip weld seams, performed by inexperienced workers, can easily lead to defects such as cavities between the annular lip seams after grinding, inconsistent weld penetration, and / or uneven weld distribution. Re-welding makes it difficult to guarantee the sealing quality, significantly shortening the service life of the cover assembly and even easily causing reactor leaks. In some cases, the thickness of the annular lip is limited; each cutting and re-welding thins the annular lip. If the thickness of the annular lip is insufficient, the entire reactor must be replaced, resulting in huge economic costs.
[0032] In this application, the fixed frame 11 can remain stationary, providing support for the rotating frame 12. The rotating frame 12 rotates relative to the fixed frame 11, thereby driving the sliding assembly 13 and the tool head 14 to rotate synchronously. During the rotation, the tool head 14 can perform cutting and / or welding, thus cutting and / or welding a full circle of the annular lip 300.
[0033] It should be noted that the direction of the axis of the annular lip 300 is the axial direction, the radial direction is the direction of the ray perpendicular to the axial direction, and the circumferential direction is the circumferential direction around the axial direction.
[0034] The auxiliary tooling provided in this embodiment allows the sliding component 13 to drive the tool head 14 to move radially and axially. This adjusts the distance between the tool head 14 and the annular lip 300, enabling the tool head 14 to approach the annular lip 300 for cutting the weld and / or welding the annular lip 300. The rotating frame 12 drives the sliding component 13 and the tool head 14 to rotate synchronously. During rotation, the tool head 14 can perform cutting and / or welding, thus cutting and / or welding a full circle of the annular lip 300. This design improves cutting and / or welding quality by automating the cutting and / or welding of the annular lip 300, reducing reliance on manual labor, mitigating the risk of quality instability caused by manual cutting and / or welding, improving the uniformity of weld cutting depth and / or the consistency of weld penetration, and enhancing processing quality and reliability.
[0035] In some embodiments, there may be multiple tool heads 14, and the multiple tool heads 14 may have different functions. Depending on the functional requirements, they may be selectively and detachably connected to the sliding component 13.
[0036] For example, one of the plurality of tool heads 14 is a cutting tool, and another of the plurality of tool heads 14 is a welding torch. When it is necessary to cut the weld, the cutting tool can be connected to the sliding assembly 13 to cut the weld. When it is necessary to weld, the welding torch can be connected to the sliding assembly 13 to weld the annular lip 300.
[0037] The specific structure of the tool head 14 is not limited and can adopt a modular design, allowing for quick replacement of tool holders, cutting tools, or welding torches. The modular tool head 14 supports quick replacement to adapt to the needs of different cutting and welding processes.
[0038] In some embodiments, the mounting opening is circular, and the cover 100 can be disposed at one end of the main body 200 in the vertical direction. Thus, the axial direction is aligned with the vertical direction. The sliding assembly 13 drives the tool head 14 to move axially to adjust the height of the tool head 14 in the vertical direction. The sliding assembly 13 also drives the tool head 14 to move radially to control the weld cutting depth and the welding torch lifting height.
[0039] In some embodiments, please refer to Figure 1 The fixed frame 11 includes a frame body 111 and multiple claws 112. The frame body 111 forms a placement space, and the rotating frame 12 is rotatably mounted on the frame body 111. The main body 200 is located within the placement space. The multiple claws 112 are spaced apart along the circumference of the frame body 111, and the claws 112 are used to abut against the main body 200.
[0040] In this embodiment, multiple claws 112 press against the main body 200 together, thereby detachably connecting the fixing frame 11 to the main body 200, which is beneficial for the rotating frame 12 to rotate around the annular lip 300.
[0041] In some embodiments, the rotating frame 12 may be located at the upper or lower end of the frame 111.
[0042] In some embodiments, the frame 111 includes multiple supports arranged circumferentially to enclose and form a placement space, and each support is detachably connected.
[0043] In this embodiment, multiple supports are arranged circumferentially to form a placement space. During the process of assembling the frame 111 to the main body 200, multiple supports can be moved to the outer periphery of the main body 200 and then the supports can be detachably connected to form a placement space. This design is beneficial for adjusting the position of multiple supports according to the radial dimension of the main body 200.
[0044] In some embodiments, the center of the circular placement space, the axis of the annular lip 300, the central axis of the cover 100, and the central axis of the body 200 coincide.
[0045] In some embodiments, a single support may be provided with at least one claw 112.
[0046] In some embodiments, the number of supports can be two, three, four, or more. For example, two supports can be arranged to form a placement space.
[0047] In some embodiments, the plurality of jaws 112 may be evenly distributed circumferentially. The number of jaws 112 may be two, three, four or more.
[0048] For example, there are four jaws 112, and the included angle between any two adjacent jaws 112 is approximately 90°. In this way, the four jaws 112 are evenly distributed circumferentially, and, in conjunction with a high-precision angle measuring instrument, the perpendicularity of the frame 111 to the axis of the annular lip 300 is detected and adjusted, improving centering accuracy. High-precision centering and perpendicularity adjustment ensure the alignment accuracy of the auxiliary tooling with the axis of the annular lip 300.
[0049] The method of detachable connection of each bracket is not limited, for example, including but not limited to snap-fit, screw connection and / or bolt connection, etc.
[0050] Taking bolted connection as an example, the wall of the support forming the placement space can be roughly arc-shaped. Two supports are connected by bolts and together enclose a circular placement space. A split annular frame 111 is adopted, with each support equipped with two claws 112 to fix the auxiliary tooling as a whole onto the cover assembly and achieve centering.
[0051] In some embodiments, please refer to Figure 1One of the chuck 112 and the frame 111 includes an adjusting rod 1a, and the other of the chuck 112 and the frame 111 includes an adjusting nut. The adjusting rod 1a and the adjusting nut are threaded together, and the adjusting rod 1a and the adjusting nut rotate relative to each other, causing the chuck 112 to move radially.
[0052] The adjusting rod 1a and the adjusting nut are threadedly engaged. Specifically, the adjusting rod 1a forms an external thread, and the adjusting nut forms an internal thread. The adjusting rod 1a is inserted into the adjusting nut, and the external and internal threads are threadedly engaged.
[0053] For example, the chuck 112 includes an adjusting rod 1a, and the frame 111 includes an adjusting nut, which can be rotated to cause the adjusting rod 1a to move the chuck 112 radially. For example, the adjusting nut can be manually rotated using a torque wrench.
[0054] For example, the chuck 112 includes an adjusting nut, and the frame 111 includes an adjusting rod 1a, which can be rotated to cause the adjusting nut to move the chuck 112 radially. For example, the adjusting rod 1a can be manually rotated using a torque wrench.
[0055] In this embodiment, the adjusting rod 1a and the adjusting nut are threaded together, converting rotation into radial movement of the chuck 112. When the chuck 112 moves radially closer to the body 200, it can press against the body 200, thereby installing the auxiliary tooling onto the body 200; when the chuck 112 moves radially away from the body 200, it can separate from the body 200, thereby removing the auxiliary tooling from the body 200. This allows for the adjustment of the chuck 112 to accommodate cover assemblies of different sizes.
[0056] The shape of the claw 112 is not limited. In some embodiments, the claw 112 is hexahedral and is located in the placement space.
[0057] In some embodiments, one of the adjusting nut and the adjusting rod 1a is rotatably connected to the frame 111. Thus, the adjusting nut and the adjusting rod 1a can rotate relative to the frame 111.
[0058] In some embodiments, one of the adjusting nut and the adjusting rod 1a is fixedly connected to the chuck 112. Thus, either the adjusting nut or the adjusting rod 1a can drive the chuck 112 to move.
[0059] In some embodiments, please refer to Figure 1 The auxiliary tooling includes a rotary power source 15, which is mounted on the fixed frame 11. The rotary power source 15 is used to drive the rotary frame 12 to rotate circumferentially. The rotary power source 15 provides power to drive the rotary frame 12 to rotate.
[0060] The rotary power source 15 includes, but is not limited to, an electric motor, for example, a servo motor. The servo motor drives the rotary frame 12 to perform precise rotational motion, which can drive the tool head 14 to move continuously along the annular lip 300° in the circumferential direction, realizing continuous circumferential cutting and / or welding.
[0061] In some embodiments, the rotary power source 15 can be connected to the rotary frame 12 via a transmission mechanism, thereby driving the rotary frame 12 to rotate.
[0062] In some embodiments, please refer to Figure 1 The slewing power source 15 and the slewing frame 12 can be located at opposite ends of the frame 111 along the axial direction. For example, the slewing power source 15 is located at the lower end of the frame 111, and the slewing frame 12 can be located at the upper end of the frame 111.
[0063] In some embodiments, please refer to Figure 1 The sliding assembly 13 includes an axial slide table and a radial slide table 131. The radial slide table 131 is disposed on the axial slide table, and the tool head 14 is disposed on the radial slide table 131. The axial slide table drives the radial slide table 131 and the tool head 14 to move axially, and the radial slide table 131 drives the tool head 14 to move radially. Thus, the axial slide table realizes the axial displacement of the tool head 14, and the radial slide table 131 realizes the radial displacement of the tool head 14. Through the rotational motion of the rotary head 12 and the cooperation of the axial slide table and the radial slide table 131, continuous and precise circumferential feed and depth control of the tool head 14 are achieved.
[0064] In some embodiments, the radial slide 131 and the tool head 14 can be fixedly connected. In this way, the radial slide 131 can drive the tool head 14 to move synchronously.
[0065] In some embodiments, the radial slide 131 and the tool head 14 can be detachably connected. This allows for the replacement of different tool heads 14 as needed. When cutting weld seams, the tool can be detachably connected to the radial slide 131; when welding is required, the welding torch can be detachably connected to the radial slide 131 to weld the annular lip 300.
[0066] An axial slide can abut against a radial slide 131, thereby pushing the radial slide 131 to move axially. In some embodiments, the radial slide 131 can slide radially with the axial slide. Exemplarily, the axial slide forms a slider, and the radial slide 131 forms a groove opening toward the slider, with the slider abutting against the groove wall. The slider pushes the radial slide 131 to move axially, while the slider remains stationary during the radial movement of the radial slide 131.
[0067] In some embodiments, the sliding assembly 13 includes an elastic element that contacts the radial slide 131 to apply an axial reset force to the radial slide 131. The elastic element applies a force to the radial slide 131 opposite to the direction of the axial slide, causing the axial slide to push the radial slide 131 away from its initial position and causing the elastic element to undergo elastic deformation. When the axial slide removes its force, the elastic element restores its elastic deformation, causing the radial slide 131 to return to its initial position in the axial direction.
[0068] In some embodiments, please refer to Figure 1 The sliding assembly 13 includes a base 132 and a force-applying component 133. The base 132 is disposed on the rotary frame 12. The force-applying component 133 is disposed on the base 132 and is connected to the axial slide to drive the axial slide to move axially.
[0069] In this embodiment, the base 132 can rotate synchronously with the slewing frame 12, and the force-applying member 133 is used to apply a force to drive the axial slide to move axially.
[0070] In some embodiments, the force-applying component 133 can be a mechanism such as a motor, a cylinder, or an electric cylinder.
[0071] In some embodiments, the force-applying component 133 can be a manual structure such as a manual wheel or a manual lever.
[0072] In some embodiments, please refer to Figure 1 The sliding assembly 13 includes a reversing structure 134, which connects the force-applying member 133 and the axial slide. The reversing structure 134 is used to convert the rotation of the force-applying member 133 into axial movement of the axial slide.
[0073] Taking the force-applying component 133 as a manual wheel as an example, when the operator rotates the force-applying component 133, the force of the force-applying component 133 is transmitted to the axial slide through the reversing structure 134, thereby driving the axial slide to move axially.
[0074] In some embodiments, the reversing structure 134 includes a gear and a rack, the gear and rack meshing, one of the gear and rack being connected to the force-applying member 133, and the other of the gear and rack being connected to the radial slide 131.
[0075] In some embodiments, the reversing structure 134 includes a nut and a lead screw, which are threaded together. One of the nut and the lead screw is connected to the force-applying member 133, and the other of the nut and the lead screw is connected to the radial slide 131.
[0076] In some embodiments, please refer to Figure 1 The sliding assembly 13 includes a sliding power source 135, which is disposed on the rotary frame 12. The sliding power source 135 drives the radial slide table 131 to slide radially.
[0077] In this embodiment, the sliding power source 135 can rotate with the slewing frame 12. The sliding power source 135 is used to provide power to drive the radial slide table 131 to slide radially.
[0078] The sliding power source 135 includes, but is not limited to, motors, cylinders, or electric cylinders.
[0079] In some embodiments, the auxiliary tooling includes a dust collection assembly disposed on the rotary frame 12, which is used to generate negative pressure to suck up dust and debris.
[0080] In this embodiment, the dust collection component can rotate with the rotating frame 12. During cutting and welding, the dust collection component can collect dust and debris, thereby improving the cleanliness of the environment around the annular lip 300, improving the working environment and efficiency. Automated continuous operation greatly improves the maintenance efficiency of the reactor and shortens downtime.
[0081] In some embodiments, the vacuuming assembly includes a negative pressure pump and a suction pipe, the negative pressure pump being connected to the suction pipe, and the suction inlet of the suction pipe being located on the underside of the tool head 14. The negative pressure pump is used to generate negative pressure, and the suction inlet is used to suck up dust and debris.
[0082] In some embodiments, the airflow at the intake is greater than or equal to 1000 m³ / h. This effectively collects metal shavings generated during cutting, preventing splashing and environmental pollution or scratching the sealing surface of the annular lip 300.
[0083] In some embodiments, when cutting with a cutting tool, the excess height of the weld is first removed by rough machining with a large depth of cut, and then the depth of cut is reduced to refine the weld penetration area until the cover 100 and the body 200 are completely separated.
[0084] In some embodiments, the auxiliary tooling includes a worktable, a vibration sensor, and a temperature monitoring module. Both the vibration sensor and the temperature monitoring module are mounted on the radial slide 131. The vibration sensor monitors the cutting force, and the temperature monitoring module monitors the cutting temperature. If the cutting force exceeds a first threshold and / or the cutting temperature exceeds a second threshold, the worktable controls the tool head 14 to slow down or stop, thereby preventing damage to the cover assembly to some extent. This improves the quality and consistency of disassembly and assembly. Precise positioning and controllable cutting depth prevent excessive thinning of the annular lip 300 caused by over-cutting, preserving usable material to some extent and extending the number of times the cover assembly can be repeatedly repaired and the overall lifespan of the reactor. The vibration sensor and temperature monitoring module monitor cutting force, temperature, and other parameters in real time, automatically shutting down in case of abnormalities, improving operational safety and automation.
[0085] It should be noted that the first and second thresholds can be set according to requirements, and this application does not impose any restrictions.
[0086] In some embodiments, the workbench can also monitor the rotational speed and position of the rotary frame 12 in real time.
[0087] In some embodiments, the auxiliary tooling has a cutting mode in which the tool is detachably connected to the sliding assembly 13 and the tool is driven to feed by the rotation of the rotary frame 12 to perform weld cutting.
[0088] In some embodiments, the auxiliary tooling has a welding mode in which the welding gun module is detachably connected to the sliding assembly 13. The welding gun module may include a support, a welding gun head, a wire feeding mechanism, and filler, and continuous welding is performed by rotating the rotary frame 12.
[0089] In some embodiments, the workbench is equipped with a physical button panel, which includes manual control keys for key functions such as an emergency stop button, a machine start / stop switch, and manual control keys for functions such as synchronous lifting and lowering of the lifting and transferring machine, and switching between cutting and welding modes. This allows for rapid intervention by operators in case of automated process malfunctions.
[0090] In some embodiments, the workbench includes a data acquisition and processing unit, which is equipped with a high-performance main control module. The data acquisition and processing unit can monitor and adjust parameters, including disassembly and assembly operation parameters and emergency stop button status parameters, etc.
[0091] The disassembly and assembly operation parameters include at least one of the following: the position of the tool head 14, the rotation speed, the cutting force, the vibration value, and the welding parameters.
[0092] Welding parameters include at least one of current, voltage, wire feed speed, and shielding gas flow rate.
[0093] In some embodiments, in the cutting mode, the cutting method of the auxiliary tooling includes: S1. Rough machining stage, specifically including: using a large depth of cut to quickly remove the excess weld height.
[0094] S2, the finishing stage, specifically includes: reducing the depth of cut, fine trimming the melt depth area, until the annular lip is completely separated at 300°.
[0095] S3. During the cutting process, specifically: the cutting status is monitored in real time by a vibration sensor, and if the cutting force exceeds the first threshold, the feed speed is automatically adjusted or the machine is stopped for protection.
[0096] In some embodiments, in the welding mode, the welding method of the auxiliary tooling includes: S10. Pre-welding preparation, specifically including: before welding, installing studs to the cover 100 and the main body 200, and using a bolt tensioning machine to pre-tighten the studs to eliminate the assembly gap between the cover 100 and the main body 200, providing a stable foundation for welding. Furthermore, before welding, the surfaces to be welded and adjacent base materials are cleaned to remove oil, oxide layers, and cutting fluid residue, exposing the natural metal color.
[0097] S20. The annular lip 300 is welded using a symmetrical skip welding process, specifically including: S201. Remove the studs at the location to be welded and at its symmetrical locations; S202. Weld symmetrical positions on both sides. During the welding process, keep the distance between the welding torch and the weld constant, and control the distance from the tungsten electrode tip of the welding torch to the annular lip 300, the wire extension length, and the angle of the wire feed guide in front of the welding direction.
