Description

Technical Field

[0001] The invention relates to the technical field of oil and gas pipeline seal processing, and in particular to a high-precision clamping oil and gas pipeline seal production tool. Background Art

[0002] During the operation of oil and gas pipelines, the quality and performance of seals are crucial, which is directly related to the safety and stability of oil and gas transportation. The existing oil and gas pipeline seal production tooling has some problems in the workpiece clamping and processing process.

[0003] On the one hand, when traditional fixtures clamp the workpiece, it is difficult to accurately detect the clamping position of the workpiece, which can easily lead to the workpiece not being clamped in place, affecting the accuracy and quality of subsequent processing. On the other hand, during the processing, the friction between the tool and the seal is large, which will accelerate the wear of the tool and reduce the service life of the tool. At the same time, it may also cause the seal to deform due to excessive local force, affecting the performance of the seal.

[0009] Preferably, a piston plate is slidably connected to the inside of the material trough, and a second spring is fixedly installed between the inner end of the piston plate and the inner wall of the material trough. The position of the second spring is located close to the center point.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The high-precision clamping oil and gas pipeline seal production tooling can detect the electrical parameters of the coil by setting the second electromagnetic coil and the sensor inside it, and compare them with the preset electrical parameters. When the clamped workpiece is in place, the electrical parameters detected by the sensor are the same as the preset values, which can accurately determine whether the installation position of the workpiece is correct, ensure accurate clamping of the workpiece, and improve processing accuracy.

[0018] 2. In the production tooling for oil and gas pipeline seals with high precision clamping, the feeding assembly inside the clamp injects magnetorheological fluid into the groove under the action of centrifugal force. Under the influence of the magnetic force of the second electromagnetic coil, the magnetorheological fluid changes from liquid to semi-solid or solid with a certain rigidity, and fits tightly to the surface of the seal, which not only increases the friction between the clamping jaws and the seal, but also makes the clamping force more evenly distributed on the surface of the seal, effectively avoiding deformation of the seal due to excessive local force.

[0019] 3. The high-precision clamping oil and gas pipeline seal production tooling, the auxiliary components can spray the magnetorheological fluid onto the outer surface of the workpiece through the nozzle. The magnetorheological fluid becomes a semi-solid state under the action of the magnetic field and has a certain viscosity. It can play a role of lubrication and buffering between the tool and the seal, reduce the direct friction between the tool and the seal, reduce tool wear, and increase tool life.

[0020] 4. In the production tooling of the high-precision clamping oil and gas pipeline seals, the first electromagnetic coil in the tool assembly is energized when the tool contacts the workpiece, so that the magnetic force near the tool becomes larger, the magnetorheological fluid becomes solid, and a supporting force opposite to the direction of tool movement is generated between the seal and the tool, offsetting the slight deformation of the workpiece when the tool contacts the workpiece, thereby ensuring the processing accuracy.

[0021] 5. The high-precision clamping oil and gas pipeline seal production tooling, the Hall sensor inside the first electromagnetic coil works based on the Hall effect, which can detect the changes in magnetic field intensity at different positions, thereby detecting the uniformity of the workpiece being processed to ensure the consistent quality of the processed seals.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] Reference Figure 1-9 A high-precision clamping oil and gas pipeline seal production tooling includes an equipment base 1, an equipment body 6 is arranged on the top of the equipment base 1, a tool assembly 2 is arranged on the top of the equipment base 1, a clamp assembly 3 is arranged on the side of the equipment body 6, an auxiliary assembly 4 and a feeding assembly 5 are arranged inside the clamp assembly 3, the clamp assembly 3 includes a clamp body 31, the clamp body 31 is rotatably connected to the right side of the equipment body 6, a second electromagnetic coil 32 is fixedly installed on the right side of the equipment body 6, the second electromagnetic coil 32 is located on the outside of the clamp body 31, a clamping claw 33 is slidably connected inside the clamp body 31, and a groove 34 is opened on the inner side end of the clamping claw 33;

[0035] The feeding assembly 5 includes a material trough 51 and a synchronous groove 57. Both the material trough 51 and the synchronous groove 57 are opened inside the clamp 33. A second connecting pipe 56 is fixedly installed between the material trough 51 and the synchronous groove 57. The second connecting pipe 56 connects the material trough 51 and the interior of the synchronous groove 57. An outlet pipe 58 is opened at the inner end of the synchronous groove 57. The outlet pipe 58 connects the interior of the synchronous groove 57 with the interior of the groove 34.

[0036] The number of outlet pipes 58 is the same as the number of grooves 34, and the position of each outlet pipe 58 corresponds to each groove 34 one by one. The inside of the material trough 51 is slidably connected with a piston plate 52, and a second spring 53 is fixedly installed between the inner end of the piston plate 52 and the inner wall of the material trough 51. The position of the second spring 53 is located near the center point, and a loading valve 54 is fixedly installed inside the clamp 33, and the loading valve 54 connects the material trough 51 with external equipment.

[0037] It should be noted that: when processing the workpiece, the raw material pipeline is clamped inside the clamp assembly 3. When clamping, the workpiece is clamped and centered by inserting it into the inside of the clamp body 31 and moving the three clamping claws 33 synchronously inward. The groove 34 acts as an anti-slip groove. When clamping, the second electromagnetic coil 32 is energized. A sensor is provided inside the second electromagnetic coil 32 to detect the electrical parameters of the coil. By presetting the electrical parameters, when the clamped workpiece is clamped in place, the electrical parameters detected by the sensor are the same as the preset values. At this time, the surface workpiece installation position is in the correct position. On the contrary, when it is different from the preset value, it means that the workpiece clamping position is not in place, thereby achieving the effect of detecting the workpiece clamping position, ensuring that the workpiece can be clamped accurately.

[0038] After the metal sealing ring workpiece is clamped, it is inserted into the second electromagnetic coil 32, so that the metal sealing ring workpiece itself generates magnetism. During processing, the clamp body 31 rotates, and the clamp body 31 drives the metal sealing ring workpiece to rotate when rotating. When the clamping jaws 33 rotate, the piston plate 52 moves outward under the action of centrifugal force. The magnetorheological fluid located on the outside can be squeezed by the piston plate 52 moving outward. After being squeezed, the magnetorheological fluid will enter the synchronous groove 57 through the second connecting pipe 56, and then be injected into the corresponding Inside the groove 34, the clamping jaw 33 is made of a material with greater electromagnetic shielding, ensuring that the magnetic force has little effect on the magnetorheological fluid inside. When the magnetorheological fluid is filled in the groove 34 and is affected by the magnetic force of the second electromagnetic coil 32, the magnetorheological fluid changes from a liquid state to a semi-solid or solid state with a certain rigidity. At this time, the magnetorheological fluid fits tightly to the surface of the seal, which not only increases the friction between the clamping jaw and the seal, but also makes the clamping force more evenly distributed on the surface of the seal, effectively avoiding deformation of the seal due to excessive local force.

[0039] Embodiment 2

[0040] refer to Figure 1-9The auxiliary component 4 includes a connector 49, which is fixedly mounted on the outside of the clamp 33. A hose 48 is fixedly mounted on the outside of the connector 49. A nozzle 47 is fixedly mounted on the outer end of the hose 48. A first connecting pipe 55 is fixedly mounted between the connector 49 and the material trough 51. The first connecting pipe 55 connects the material trough 51 and the inside of the hose 48.

[0041] A side plate 46 is fixedly mounted on the side of the clamping jaw 33, a nozzle 47 is rotatably connected between the side plates 46, a gear 45 is fixedly mounted on the outside of the side plates 46, and the gear 45 and the nozzle 47 are fixedly connected via a rotating shaft that movably penetrates the inside of the side plates 46. A connecting rod 42 is fixedly mounted on the side of the clamping jaw 33, an outer cylinder 41 is fixedly mounted on the outer end of the connecting rod 42, a moving plate 410 is slidably connected inside the outer cylinder 41, a moving rod 43 is fixedly mounted on the bottom of the moving plate 410, a rack 44 is fixedly mounted on the bottom of the moving rod 43, and the rack 44 and the gear 45 are meshed with each other.

[0042] A first spring 411 is fixedly installed between the moving plate 410 and the inner wall of the outer tube 41 . The first spring 411 is sleeved on the outer side of the moving rod 43 . The moving rod 43 movably penetrates the side wall of the outer tube 41 .

[0043] It should be noted that when the magnetorheological fluid is discharged through the piston plate 52, a portion of the magnetorheological fluid enters the interior of the connector 49 through the first connecting pipe 55, and then is sprayed out through the hose 48 through the nozzle 47. The magnetorheological fluid can be sprayed onto the outer surface of the workpiece through the nozzle 47, and during spraying, the movable plate 410 is moved outwardly under the action of centrifugal force, and the movable plate 410 moves outwardly, which can drive the movable rod 43 and the rack 44 to move outward, and the rack 44 moves outwardly, which can drive the gear 45 to rotate, and the rotation of the gear 45 can drive the nozzle 47 to rotate, and the nozzle 47 can rotate. By swinging the nozzle 47, the magnetorheological fluid can be sprayed onto the entire outside of the workpiece, and the magnetorheological fluid becomes a semi-solid state under the action of the magnetic force on the workpiece surface after being sprayed, and has a certain viscosity, and the magnetorheological fluid is applied to the entire outside of the workpiece during the rotation of the workpiece itself. The magnetorheological fluid can play a lubricating and buffering role between the tool and the seal. During the cutting process, the friction between the tool and the surface of the seal is one of the main causes of tool wear. The semi-solid or solid structure formed by the magnetorheological fluid under the action of the magnetic field can effectively reduce the direct friction between the tool and the seal.

[0044] Embodiment 3

[0045] refer to Figure 1-9The tool assembly 2 includes a translation guide rail 21, which is fixedly installed on the top of the equipment base 1. The top of the translation guide rail 21 is slidably connected with a moving frame 22. The top of the moving frame 22 is provided with a second adjustment frame 23, and the top of the second adjustment frame 23 is fixedly installed with a tool frame 24.

[0046] An electric slide rail 25 is fixedly installed on the top of the moving frame 22 , a track slider 26 is slidably connected to the outer side of the electric slide rail 25 , a support rod 27 is fixedly installed on the top of the track slider 26 , and a first electromagnetic coil 28 is fixedly installed on the top of the support rod 27 .

[0047] It should be noted that: when the tool is cutting the workpiece, the first electromagnetic coil 28 is first sleeved on the outside of the workpiece when moving, and then the tool is moved to the specified position for cutting. When the tool contacts the workpiece, the first electromagnetic coil 28 is energized, so that the magnetic force near the tool becomes larger. At this time, the magnetorheological fluid becomes solid. At this time, the magnetorheological fluid can generate a supporting force in the opposite direction of the tool movement between the seal and the tool under the action of the magnetic field. This supporting force can offset the slight deformation of the workpiece when the tool contacts the workpiece, thereby ensuring the processing accuracy. The electric slide rail 25 drives the track slider 26 to move, which can drive the first electromagnetic coil 28 to move without affecting the tool change.

[0048] The Hall sensor is placed inside the first electromagnetic coil 28. The Hall sensor works based on the Hall effect. When a magnetic field passes through the sensor, a voltage signal proportional to the magnetic field strength is generated. Since the magnetic field distribution changes due to the rotation of the uneven material, the Hall sensor can detect the change in magnetic field strength at different positions. This change can be used to detect the uniformity of the workpiece being processed, thereby achieving the purpose of detecting the workpiece during processing.

[0049] Working principle: Workpiece clamping and position detection: The raw material pipeline is clamped inside the clamp assembly 3, and the three clamping jaws 33 move synchronously inward to achieve the clamping and centering of the workpiece. The groove 34 acts as an anti-slip groove. The second electromagnetic coil 32 is energized, and its internal sensor detects the electrical parameters of the coil and compares them with the preset electrical parameters to determine whether the workpiece clamping position is in place. If the detected electrical parameters are the same as the preset values, the workpiece installation position is correct; otherwise, it means that the workpiece clamping position is not in place;

[0050] Optimization of magnetorheological fluid filling and clamping force: After the metal sealing ring workpiece is clamped, it is inserted into the second electromagnetic coil 32 to generate magnetism. The rotation of the fixture body 31 drives the metal sealing ring workpiece to rotate. When the clamp 33 rotates, under the action of centrifugal force, the piston plate 52 moves outward to squeeze the magnetorheological fluid on the outside. The magnetorheological fluid enters the synchronous groove 57 through the second connecting pipe 56, and then is injected into the corresponding groove 34 through the outlet pipe 58. Since the clamp 33 is made of a material with greater electromagnetic shielding, the magnetic force has little effect on the internal magnetorheological fluid. Under the influence of the magnetic force of the second electromagnetic coil 32, the magnetorheological fluid changes from liquid to semi-solid or solid, and fits tightly to the surface of the seal to optimize the clamping force.

[0051] Magnetorheological fluid spraying and lubrication buffering: When the piston plate 52 discharges the magnetorheological fluid, a part of the magnetorheological fluid enters the connector 49 through the first connecting pipe 55, and then is sprayed from the nozzle 47 to the outer surface of the workpiece through the hose 48. Under the action of centrifugal force, the movable plate 410 moves outward, driving the movable rod 43 and the rack 44 to move outward, and the rack 44 drives the gear 45 to rotate, thereby driving the nozzle 47 to rotate, so that the nozzle 47 swings, and the magnetorheological fluid is sprayed to the entire outside of the workpiece. Under the action of the magnetic force on the surface of the workpiece, the magnetorheological fluid becomes a semi-solid state with viscosity, and is coated on the entire outside of the workpiece when the workpiece rotates, playing a lubricating and buffering role between the tool and the seal;

[0052] Machining accuracy assurance and workpiece uniformity detection: When the tool cuts the workpiece, the first electromagnetic coil 28 is first put on the outside of the workpiece, and the tool is moved to the specified position. When the tool contacts the workpiece, the first electromagnetic coil 28 is energized to increase the magnetic force near it, and the magnetorheological fluid becomes solid, generating a supporting force in the opposite direction of the tool movement between the seal and the tool to offset the slight deformation of the workpiece and ensure machining accuracy. The electric slide rail 25 drives the track slider 26 to move, which can drive the first electromagnetic coil 28 to move without affecting the tool change. The Hall sensor inside the first electromagnetic coil 28 detects the change of magnetic field strength at different positions based on the Hall effect, thereby detecting the uniformity of the workpiece being processed.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
