Technical Field
[0001] This invention relates to the field of turning equipment technology, and in particular to a turning equipment for the end face of a corrugated compensator. Background Technology
[0002] In the technical field of bellows compensator end face machining equipment, the machining of the flange end face of the bellows compensator after welding is generally completed by a conventional horizontal lathe. During machining, the rigid end tube of one end of the workpiece is clamped by the spindle chuck and the whole body is rotated. The sealing working surfaces of the flanges at both ends are cut one by one. During the machining process, the middle section of the bellows is suspended in the air. Under the combined action of its own weight and cutting impact force, it is prone to bending deformation and lateral vibration. This will make it difficult to ensure the flatness of the flange end face, the perpendicularity of the end face to the axis, and the parallelism of the two end faces. It will also easily cause bellows waveform distortion and increase the additional alternating stress at the circumferential weld, which will directly affect the sealing performance and long-term service life of the product. Meanwhile, traditional external clamping chucks act directly on the outer wall of thin-walled pipes. Improper control of clamping force can easily cause the pipe wall to collapse and become out of round. Furthermore, the flanges at both ends need to be clamped and turned over twice to complete the processing. The alignment error of the second clamping will further accumulate the geometric tolerances. The auxiliary time for clamping and alignment is long, and the overall processing efficiency is low, making it difficult to meet the dual requirements of processing accuracy and production efficiency under mass production.

A guide groove is formed on the surface of the rotating rod, and a turning groove is formed on one side of the guide groove. Limiting rings are fixedly disposed on both ends of the rotating rod near one set of fixing blocks. A connecting sleeve is fixedly disposed on one corresponding end of each of the two sets of fixing blocks. A connecting ring is formed on the outer side of the connecting sleeve, and a connecting rod is fixedly disposed on the upper end of the connecting ring. A guide block is fixedly disposed on the inner side of one set of fixing blocks near the turning groove. Five sets of clamping rods are slidably disposed on the outer side of the rotating rod.

[0007] Preferably, the set of sliders closer to the motor is fixedly connected to the slide plate, and the set of sliders farther from the motor is threadedly connected to the threaded rod and slidably disposed in the slide groove, wherein the gear and the tooth groove are meshed.

[0011] Preferably, the clamping rod is slidably disposed with the guide groove, the connector is movably connected to the middle position of each connecting rod corresponding to the hinged connecting rod, and the butterfly spring is adapted to the telescopic port.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the bellows compensator inside the disc. First, use the hydraulic cylinder on one side to push the connecting rod to move along the arc-shaped opening, causing the connected drive ring to rotate in the disc. The moving guide port pushes the guide shaft and U-shaped frame towards the center, pre-clamping and positioning the flange on one side of the bellows compensator. Then, drive a set of threaded sliders to move in the slide groove by rotating the threaded rod until the moving disc corresponds to the flange on the other side. Then, start the corresponding hydraulic cylinder to clamp and fix it, realizing the initial positioning of the bellows compensator as a whole. Subsequently, the meshing tooth groove and connecting sleeve are rotated by the motor and gear to facilitate end face processing.
[0013] 2. The moving disc drives the connected fixed block to move together. The connecting rod pulls the hinged connecting rod, causing the five sets of clamping rods to slide on the rotating rod and open at equal intervals. When the guide block slides along the guide groove to the turning groove, corresponding to the position of the corrugated groove of the corrugated compensator, the guide block pushes the rotating rod to rotate counterclockwise along the two sets of fixed blocks, causing the five sets of clamping rods to rotate into the corrugated groove, achieving the purpose of synchronous clamping and wrapping. This wraps the corrugated section of the corrugated compensator and stabilizes it at the position of the rotation axis, avoiding the impact of its own gravity and inertia on the clamping and end face processing effect during the rotation. When the clamping rods rotate into the corrugated groove, the butterfly spring pushes the flanges on both sides to the position of the clamping mechanism on both sides. With the pre-tightening state of the hydraulic cylinders on both sides, they are automatically aligned and clamped before end face processing.
[0014] 3. When pre-tightening the bellows compensator, the roller contacts the bellows compensator flange, and the return spring supports the movable shell and the roller. During clamping, the roller can be retracted and moved into the return spring, and then clamped by the clamping plate. The rolling setting of the roller can also push the bellows compensator laterally during pre-tightening for position adjustment. Attached Figure Description

The positioning mechanism 4 includes two sets of discs 41 fixedly disposed inside two sets of fixed rings 36. A drive ring 42 is movably disposed inside the disc 41. Three sets of movable openings 43 are opened inside the disc 41. A U-shaped frame 44 is movably disposed inside each of the three sets of movable openings 43.

[0020] One set of two sliders 34 near the motor 37 is fixedly connected to the slide plate 31, and the other set of sliders 34 away from the motor 37 is threadedly connected to the threaded rod 33 and slidably disposed in the slide groove 32.

[0021] Furthermore, the bellows compensator is placed inside the disc 41. First, the connecting rod 48 is moved along the arc-shaped opening 49 by the use of the hydraulic cylinder 410 on one side, causing the connected drive ring 42 to rotate in the disc 41. The moving guide opening 47 pushes the guide shaft 45 and the U-shaped frame 44 towards the center, pre-clamping and positioning the flange on one side of the bellows compensator. Then, the threaded rod 33 is rotated to drive a set of threaded sliders 34 to move in the slide groove 32 until the moving disc 41 corresponds to the flange on the other side. Then, the corresponding hydraulic cylinder 410 is activated to clamp and fix it, realizing the initial positioning of the bellows compensator as a whole. Subsequently, the meshing tooth groove 39 and the connecting sleeve 35 are driven by the motor 37 and gear 38 to rotate, which facilitates the end face processing.
[0022] A square groove 461 is provided on the inner side of the clamping plate 46. A movable shell 462 is movably provided on the inner side of the square groove 461.

Two sets of return springs 464 are fixedly provided between the middle position of the movable shell 462 and the inner wall of the square groove 461.
[0023] The upper side of the roller 463 protrudes to the outside of the movable shell 462 and is higher than the transverse friction strip on the clamping plate 46.
[0024] Furthermore, during pre-tightening of the bellows compensator, the roller 463 contacts the bellows compensator flange, and the return spring 464 supports the movable housing 462 and the roller 463. During clamping, the roller 463 moves into the return spring 464 and is then clamped by the clamping plate 46. The rolling setting of the roller 463 allows the bellows compensator to be moved laterally during pre-tightening for position adjustment.
[0025] The packaging mechanism 5 includes three sets of fixing blocks 51 fixedly disposed on the outer sides of two sets of discs 41. Rotating rods 52 are movably disposed on the inner sides of each set of fixing blocks 51. Guide grooves 53 are formed on the surface of the rotating rods 52, and a turning groove 54 is provided on one side of each guide groove 53. Limiting rings 55 are fixedly disposed on both ends of the rotating rods 52 near each set of fixing blocks 51. Connecting sleeves 56 are fixedly disposed on the corresponding ends of each set of fixing blocks 51. Connecting rings 57 are formed on the outer sides of the connecting sleeves 56. A connecting rod 58 is fixedly installed at the upper end. A guide block 59 is fixedly installed on the inner side of one of the two sets of fixed blocks 51 near the turning groove 54. Five sets of clamping rods 510 are slidably installed on the outer side of the rotating rod 52. A connector 511 is fixedly installed at the upper end of each of the five sets of clamping rods 510. A hinged connecting rod 512 is movably connected to the two sets of connecting rods 58 and the five sets of connectors 511. A telescopic opening 513 is opened on the lower side of each of the five sets of clamping rods 510. A butterfly spring 514 is fixedly installed on the inner side of each of the five sets of telescopic openings 513.
[0026] A ring is fixedly installed on the side of the rotating rod 52 away from the limiting ring 55. Two sets of connecting rods 58 are respectively connected to the two ends of the hinged connecting rod 512. Two sets of guide blocks 59 are inserted into the turning groove 54 and are adapted to the guide groove 53 and the turning groove 54. The clamping rod 510 is slidably set with the guide groove 53. The connector 511 is movably connected to the middle position of each connecting rod segment corresponding to the hinged connecting rod 512. The butterfly spring 514 is adapted to the telescopic port 513.
[0027] Furthermore, the moving disc 41 drives the connected fixed block 51 to move together, and the connecting rod 58 pulls the hinged connecting rod 512, causing the five sets of clamping rods 510 to slide on the rotating rod 52 and open at equal intervals. When the guide block 59 slides along the guide groove 53 to the turning groove 54, the guide block 59 pushes the rotating rod 52 to rotate counterclockwise along the two sets of fixed blocks 51, causing the five sets of clamping rods 510 to rotate into the corrugated groove, achieving the purpose of synchronous clamping and wrapping, thereby wrapping the corrugated pipe section of the corrugated compensator and stabilizing it at the position of the rotation axis. This avoids the clamping and end face processing effect being affected by its own gravity and inertia during the rotation process. When the clamping rods 510 rotate into the corrugated groove, the butterfly spring 514 pushes the flanges on both sides to the position of clamping by the positioning mechanism 4 on both sides. With the pre-tightening state of the hydraulic cylinders 410 on both sides, they are automatically aligned and clamped before end face processing.
[0028] In this embodiment: During use, the corrugated compensator is placed inside the disc 41. First, by using the hydraulic cylinder 410 on one side, the connecting rod 48 is pushed to move along the arc-shaped opening 49, causing the connected drive ring 42 to rotate in the disc 41. The moving guide opening 47 pushes the guide shaft 45 and the U-shaped frame 44 towards the center, pre-clamping and positioning the flange on one side of the corrugated compensator. Then, by rotating the threaded rod 33, a set of threaded sliders 34 are driven to move in the slide groove 32 until the moving disc 41 corresponds to the flange on the other side. Then, the corresponding hydraulic cylinder 410 is activated to clamp and fix it, realizing the initial positioning of the corrugated compensator as a whole. Subsequently, the motor 37 and the gear 38 drive the meshing tooth groove 39 and the connecting sleeve 35 to rotate, which facilitates the end face processing.
[0029] At the same time, the moving disc 41 drives the connected fixed block 51 to move together, and the connecting rod 58 pulls the hinged connecting rod 512, so that the five sets of clamping rods 510 slide on the rotating rod 52 and open at equal intervals. When the guide block 59 slides along the guide groove 53 to the turning groove 54, the guide block 59 pushes the rotating rod 52 to rotate counterclockwise along the two sets of fixed blocks 51, driving the five sets of clamping rods 510 into the corrugated groove, so as to achieve the purpose of synchronous clamping and wrapping, thereby wrapping the corrugated pipe section of the corrugated compensator and stabilizing it at the position of the rotation axis. This avoids the clamping and end face processing effect being affected by its own gravity and inertia during the rotation process. When the clamping rods 510 rotate into the corrugated groove, the butterfly spring 514 pushes the flanges on both sides to the position of clamping by the positioning mechanism 4 on both sides. With the pre-tightening state of the hydraulic cylinders 410 on both sides, they are automatically aligned and clamped before end face processing.
[0030] In addition, when the bellows compensator is pre-tightened, the roller 463 contacts the bellows compensator flange, and the return spring 464 supports the movable housing 462 and the roller 463. When clamped, the roller 463 moves into the return spring 464 and is then clamped by the clamping plate 46. The rolling setting of the roller 463 can also push the bellows compensator laterally during pre-tightening for position adjustment.
[0031] The control and connection methods of the electronic equipment and turning machine tool structure in this invention are common knowledge in the field. Their working principles are well-known technologies, and the appropriate model is selected according to actual use, so they will not be elaborated further here.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
