Abstract
Description
Technical Field
[0001] This invention relates to the field of strip alloy welding, specifically to a strip alloy electron beam welding apparatus. Background Technology
[0002] Electron beam welding is a precision welding technology that uses a high-energy electron beam to bombard metal workpieces, causing them to melt locally and form a weld. With its irreplaceable high precision and deep penetration characteristics, electron beam welding has become a key technology in the field of high-end manufacturing, especially in aerospace engines and nuclear reactor components where it is almost irreplaceable. Electron beam welding plays a crucial role in the manufacturing of welding equipment, especially in the manufacture of high-precision, high-performance equipment, where it exhibits unique advantages. It is particularly suitable for vacuum systems, high-temperature resistant components, and the joining of dissimilar materials.
[0003] Strip alloys are typically 0.05 to 1 mm thick. Traditional welding methods are prone to burn-through. Electron beam welding, with its superior thermal control and environmental adaptability, has become a solution for strip alloy welding, especially in high-end fields where zero defects are required.
[0004] The following problems exist in the existing technology that have not been well resolved: When the existing strip alloy is electron beam welded, the strip alloy needs to be fixed and limited by a clamping device during the welding process. After the strip alloy is welded, when the clamping device is unlocked at the same time after welding, the stress of the strip alloy is redistributed instantly, which will lead to local stress concentration, and there is a risk of deformation and cracks. When the strip alloy suddenly loses its constraint, it will produce elastic rebound, which will cause deformation. Summary of the Invention

[0007] Preferably, the moving device includes an adjusting disc fixedly connected to the gear ring, the adjusting disc having an inclined groove around its circumference corresponding to a plurality of locking elements, the support sleeve having a moving rod corresponding to the inclined groove, the moving rod being slidably connected to the support sleeve and extending toward the inclined groove, the moving rod having a moving plate fixedly connected to the moving rod, the moving plate engaging with the locking elements corresponding to the support sleeve.
[0008] Preferably, each of the locking components includes a locking frame slidably connected to the end face of the support sleeve facing the fixed sleeve, a connecting spring connecting the locking frame and the support sleeve, a locking slot on the support sleeve, a moving plate on the moving rod abutting against the locking frame, an inclined block on the locking frame, a telescopic spring connected to the inclined block inside the locking frame, and the inclined block engaging with the locking slot.
[0009] Preferably, the locking component further includes a push rod slidably connected to the outer wall of the support sleeve, a return spring connected between the push rod and the support sleeve, a positioning frame hinged to the outer wall of the fixed sleeve, the positioning frame and the push rod being hinged together, a wedge-shaped groove being provided on the push rod, a wedge-shaped plate extending into the wedge-shaped groove on the locking frame, and the push rod moving towards the positioning frame when the wedge-shaped plate extends into the wedge-shaped groove in the push rod, and a partition plate being provided between adjacent positioning frames on the outer wall of the fixed sleeve, the partition plate being slidably connected to the outer wall of the fixed sleeve, and the edge of the partition plate being inclined.
[0010] Preferably, the unlocking device includes a connecting rod shaft connected to a rotating rod, a rotating frame fixedly connected to the connecting rod, an annular groove formed on the inner wall of the support sleeve, a limiting wheel rotatably connected to the rotating frame and located in the annular groove, a support plate fixedly connected to the inner wall of the support sleeve, the support plate rotatably connected to the connecting rod, a rotating helical gear rotatably connected to the support plate, a one-way shaft provided inside the rotating helical gear, and the one-way shaft connected to the connecting rod shaft.
[0011] Preferably, a transmission rod is rotatably connected to the rotating frame. One end of the transmission rod is fixedly connected to a transmission helical gear that meshes with the rotating helical gear. The other end of the transmission rod is axially connected to an eccentric turntable. An eccentric frame is hingedly connected to the eccentric turntable. An unlocking frame is slidably connected to the rotating frame, and the unlocking frame is hingedly connected to the eccentric frame. The bottom of the unlocking frame is correspondingly set to the lock opening.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the moving device moves slowly by rotating the rotating disk. The slow movement of the moving device allows the strip alloy to be placed on the cylindrical part and its position to be gradually adjusted. The slow adjustment can prevent the strip alloy from deforming or shifting due to sudden force. The slow adjustment also facilitates real-time monitoring and adjustment of the tension of the strip alloy, avoiding local over-tightness or over-looseness.
[0013] In this invention, a moving device synchronously drives several locking components to position the strip alloy on the support sleeve around its circumference. The simultaneous action of multiple locking components ensures that the strip alloy is subjected to uniform force in the circumferential direction. Synchronous locking can avoid the twisting or misalignment of the strip alloy caused by single-point force application, thus improving assembly accuracy. Compared with adjusting the locking components one by one, synchronous driving can shorten the assembly time, ensure the symmetrical position of the strip alloy on the cylindrical component, and avoid errors caused by step-by-step operation.
[0014] In this invention, when the rotating rod is reset and rotated, the gear ring drives the moving device to move and reset slowly. The unlocking bracket on the rotating frame will then abut against the inclined blocks on several locking parts in sequence, unlocking several locking parts in sequence. This sequential unlocking allows the stress in the welding area of the strip alloy to be released gradually after welding, avoiding local stress concentration caused by the instantaneous redistribution of stress during synchronous unlocking, reducing the risk of deformation and cracking, and preventing the cylindrical part and strip alloy from elastically rebounding due to the sudden loss of constraint when all locking parts are released at the same time, which could lead to uncontrollable deformation.
[0015] In this invention, the high-temperature area after electron beam welding needs to be cooled slowly. The locks are unlocked sequentially to avoid rapid cooling caused by simultaneous release of constraints. After each lock is unlocked, the weld quality and deformation can be detected. If a problem is found, the process can be paused and adjusted to avoid batch failures.
[0016] In this invention, when the unlocking device unlocks the first locking member, the moving plate on the moving rod approaches the lock opening. When the locking frame on the first locking member resets under the action of the connecting spring, the locking frame will be in close contact with the moving plate. At this time, the positioning frame is not completely detached from the strip alloy, and the positioning frame and the strip alloy are in a close contact state. When the second locking member is released, the locking member will slowly separate from the strip alloy under the restriction of the moving device. Until the last locking member separates from the strip alloy, the last locking member is completely reset. The welded strip alloy is released through a phased and gradual unlocking method. The close contact state of the first locking member provides partial constraint. The subsequent locking members gradually separate, allowing the strip alloy to slowly adapt to stress changes and maintain stability. When the last locking member is completely reset, the strip alloy is in a near-free state. At this time, most of the residual stress has been released, reducing the risk of strip alloy deformation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1 to 12 This invention provides a technical solution: a strip alloy electron beam welding device, comprising a support sleeve 1, a rotary motor 11 fixedly connected to the outer wall of the support sleeve 1, a fixed sleeve plate 12 fixedly connected to the end face of the support sleeve 1 away from the rotary motor 11, a moving device 3 provided on the end face of the support sleeve 1 located on the fixed sleeve plate 12, the main shaft of the rotary motor 11 extending inward toward the support sleeve 1, and the main shaft of the rotary motor 11 being connected to the rotating device 2, the rotating device 2 being kinetically connected to the moving device 3, the moving device 3 being provided with a plurality of locking elements 4, the plurality of locking elements 4 being slidably disposed on the end face of the support sleeve 1 facing the fixed sleeve plate 12, and the plurality of locking elements 4 abutting against the rotating device 2, the rotating device 2 also being connected with an unlocking device 5 for sequentially unlocking the plurality of locking elements 4.
[0021] In this embodiment, the rotating device 2 includes a rotating rod 21 that is shaft-connected to the main shaft of the rotating motor 11. A driving cone disk 22 is shaft-connected to the rotating rod 21. A fixing collar 23 is fixedly connected to the inner wall of the support sleeve 1. A rotating rod 24 is rotatably connected to the fixing collar 23. A driven cone disk 25 is fixedly connected to the rotating rod 24. A connecting belt 26 is sleeved between the driving cone disk 22 and the driven cone disk 25. A rotating gear 27 is fixedly connected to the rotating rod 24. A rotating disk 28 is rotatably connected to the outer wall of the support sleeve 1. A gear ring 29 that meshes with the rotating gear 27 is provided on the inner wall of the rotating disk 28. When electron beam welding a strip alloy to a cylindrical component, the cylindrical component is placed on a fixed sleeve 12, and then the strip alloy is wrapped around the cylindrical component. A rotary motor 11 drives a rotating rod 21 to rotate, which in turn causes the driving cone disk 22 to rotate. The rotation of the driving cone disk 22, via a connecting belt 26, causes the driven cone disk 25 to rotate. Both the driving and driven cone disks 22 and 25 are constructed of conical wheels. The connecting belt 26 is forced to operate at different radii on the driving and driven cone disks 22 and 25, thereby adjusting the rotational speed of the driven cone disk 25. The speed is less than the rotational speed of the active cone disk 22, which in turn slows down the rotational speed of the rotating rod 24. The slow rotation of the rotating rod 24 drives the rotating gear 27 to drive the gear ring 29 to drive the rotating disk 28 to rotate slowly. Thus, the slow rotation of the rotating disk 28 drives the moving device 3 to move slowly. The slow movement of the moving device 3 can gradually adjust the position of the strip alloy when it is placed on the cylindrical part. The slow adjustment can avoid the strip alloy from deforming or shifting due to sudden force. The slow adjustment facilitates real-time monitoring and adjustment of the tension of the strip alloy, avoiding local over-tightness or over-looseness.
[0022] In this embodiment, the moving device 3 includes an adjusting disk 31 fixedly connected to the gear ring 29. The adjusting disk 31 has a slanted groove 32 around its circumference, which corresponds to a plurality of locking elements 4. The support sleeve 1 is provided with a moving rod 33 corresponding to the slanted groove 32. The moving rod 33 is slidably connected to the support sleeve 1 and extends into the slanted groove 32. A moving plate 34 is fixedly connected to the moving rod 33. The moving plate 34 abuts against the locking elements 4 corresponding to the support sleeve 1. Each of the locking components 4 includes a locking frame 41 that is slidably connected to the end face of the support sleeve 1 facing the fixed sleeve 12. A connecting spring 42 is connected between the locking frame 41 and the support sleeve 1. A locking slot 43 is provided on the support sleeve 1. A moving plate 34 on the moving rod 33 abuts against the locking frame 41. An inclined block 44 is provided on the locking frame 41. A telescopic spring 45 connected to the inclined block 44 is provided inside the locking frame 41. The inclined block 44 is connected to the locking slot 43. When the rotating disk 28 rotates, it will drive the adjusting disk 31 to rotate. The several inclined grooves 32 opened on the adjusting disk 31 will drive the moving rod 33 on the supporting sleeve 1 to slide on the supporting sleeve 1. The moving rod 33 will drive the moving plate 34 to move towards the direction of the strip alloy. At this time, the moving plate 34 will abut against the outer wall of the locking frame 41, thereby driving the locking frame 41 to move towards the direction of the strip alloy in sync. When it moves to the lock opening 43, the inclined surface of the inclined block 44 set on the locking frame 41 will abut against the outer wall of the lock opening 43, so that the inclined block 44 retracts on the locking frame 41 and docks with the lock opening 43. The moving device 3 synchronously drives several locking parts 4 to position the strip alloy on the support sleeve 1 around the circumference of the strip alloy. The simultaneous action of multiple locking parts 4 ensures that the strip alloy is subjected to uniform force in the circumferential direction. Synchronous locking can avoid the strip alloy from twisting or misaligning due to single-point force application, thereby improving assembly accuracy. Compared to adjusting the locking components 4 one by one, synchronous driving can shorten the assembly time, ensure the symmetrical position of the strip alloy on the cylindrical component, and avoid errors caused by step-by-step operation.
[0023] In this embodiment, the locking member 4 further includes a push rod 46 slidably connected to the outer wall of the support sleeve 1. A return spring 47 is connected between the push rod 46 and the support sleeve 1. A positioning frame 48 is hingedly connected to the outer wall of the fixed sleeve 12. The positioning frame 48 is hinged to the push rod 46. A wedge-shaped groove 49 is provided on the push rod 46. A wedge-shaped plate 410 is provided on the locking frame 41 extending toward the wedge-shaped groove 49. When the wedge plate 410 extends toward the wedge-shaped groove 49 in the push rod 46, the push rod 46 moves toward the positioning frame 48. A partition plate 411 is also provided on the outer wall of the fixed sleeve 12 between adjacent positioning frames 48. The partition plate 411 is slidably connected to the outer wall of the fixed sleeve 12, and the edge of the partition plate 411 is inclined. When the wedge-shaped plate 410 on the locking frame 41 extends into the wedge-shaped groove 49 on the push rod 46, the push rod 46, driven by the wedge surface, can drive the positioning frame 48 to abut against the strip alloy. When the cylindrical part is installed on the fixing sleeve 12, the strip alloy is wrapped around the outer wall of the cylindrical part. Several locking pieces 4 are wrapped around the outer wall of the strip alloy, providing multi-point restriction to ensure stable fixation between the strip alloy and the cylindrical part during the welding process. When the strip alloy is wound onto the cylindrical part, the baffle plate 411 is moved so that the inclined surface at the edge of the baffle plate 411 is located between the strip alloy and the cylindrical part. This ensures that when the strip alloy and the cylindrical part are welded, a gap of 0.1~0.3mm is maintained between the strip alloy and the cylindrical part. The gap allows the molten metal to better fill the joint, forming a uniform and defect-free weld. This avoids local stress concentration caused by thermal expansion due to excessively tight assembly during electron beam welding. The gap can buffer deformation and reduce the tendency to crack.
[0024] In this embodiment, the unlocking device 5 includes a connecting rod 51 that is shaft-connected to the rotating rod 21. A rotating frame 52 is fixedly connected to the connecting rod 51. An annular groove 53 is provided on the inner wall of the support sleeve 1. A limiting wheel 54 is rotatably connected to the rotating frame 52 and is located in the annular groove 53. A support plate 55 is also fixedly connected to the inner wall of the support sleeve 1. The support plate 55 is rotatably connected to the connecting rod 51. A rotating helical gear 56 is rotatably connected to the support plate 55. A one-way shaft is provided inside the rotating helical gear 56 and is shaft-connected to the connecting rod 51. A transmission rod 57 is rotatably connected to the rotating frame 52. One end of the transmission rod 57 is fixedly connected to a transmission helical gear 58 that meshes with the rotating helical gear 56. The other end of the transmission rod 57 is axially connected to an eccentric turntable 59. An eccentric frame 510 is hinged to the eccentric turntable 59. An unlocking frame 511 is slidably connected to the rotating frame 52. The unlocking frame 511 is hinged to the eccentric frame 510. The bottom of the unlocking frame 511 is correspondingly set to the lock opening 43. During the welding process between the strip alloy and the cylindrical part, the rotating rod 21 rotates and drives the connecting rod 51 to rotate synchronously. At this time, the rotation of the connecting rod 51 drives the one-way shaft to rotate, which in turn causes the rotating helical gear 56 to rotate synchronously. At this time, the rotating helical gear 56 and the transmission helical gear 58, which are in the meshing state, rotate synchronously with the connecting rod 51. The transmission helical gear 58 does not rotate under the drive of the rotating helical gear 56. At this time, the rotating disk 28 rotates and drives the moving device 3 to control several locking parts 4 to clamp the strip alloy. After the strip alloy and the cylindrical part are welded by electron beam welding, the rotary motor 11 drives the rotating rod 21 to rotate. When the rotating rod 21 rotates in the opposite direction, the gear ring 29 slowly rotates and resets under the deceleration action of the active cone disk 22 and the driven cone disk 25. At this time, the moving plate 34 that abuts against the locking frame 41 will slowly reset. When the rotating rod 21 rotates in the reverse direction, the reverse rotation of the connecting rod 51 will not drive the one-way shaft to rotate. The rotating helical gear 56, which is mounted on the one-way shaft, will remain stationary on the support plate 55. When the connecting rod 51 drives the rotating frame 52 to rotate in the reverse direction, since the rotating helical gear 56 is stationary, the transmission helical gear 58, driven by the rotating frame 52, will rotate around the connecting rod 51 under the constraint of the rotating helical gear 56. At this time, the rotation of the rotating helical gear 56 will drive the transmission rod 57 to rotate. The eccentric turntable 59, which is eccentrically set on the transmission rod 57, will rotate. The eccentric turntable 59 drives the eccentric frame 510 to move. The eccentric frame 510 will drive the unlocking frame 511 to move back and forth on the rotating frame 52. At this time, the unlocking frame 511 moves down and will abut against the inclined block 44 at the lock opening 43, causing the inclined block 44 to separate from the lock opening 43. When the inclined block 44 separates from the lock opening 43, the locking frame 41 will reset under the action of the connecting spring 42, thereby separating the positioning frame 48 that fixes the strip alloy from the strip alloy. When the rotating rod 21 is reset and rotated, the gear ring 29 drives the moving device 3 to move and reset slowly. The unlocking bracket 511 on the rotating frame 52 will then abut against the inclined blocks 44 on several locking parts 4 in sequence, unlocking several locking parts 4 in sequence. This sequential unlocking allows the stress in the welding area of the strip alloy to be released gradually after welding, avoiding local stress concentration caused by the instantaneous redistribution of stress during synchronous unlocking, reducing the risk of deformation and cracks, and preventing the cylindrical parts and strip alloy from elastically rebounding due to the sudden loss of constraint when all locking parts 4 are released at the same time, which could cause uncontrollable deformation. After electron beam welding, the high-temperature area needs to be cooled slowly. Unlocking should be done sequentially to avoid rapid cooling caused by simultaneous release of constraints. After unlocking each locking piece 4, the weld quality and deformation can be checked. If a problem is found, the process can be paused and adjusted to avoid batch failure. When the gear ring 29 drives the moving device 3 to slowly move and reset, when the unlocking device 5 unlocks the first locking piece 4, the moving plate 34 on the moving rod 33 approaches the lock opening 43. When the locking frame 41 on the first locking piece 4 resets under the action of the connecting spring 42, the locking frame 41 will be in close contact with the moving plate 34. At this time, the positioning frame 48 is not completely detached from the strip alloy, and the positioning frame 48 and the strip alloy are in close contact. When the second locking piece 4 is released, the locking piece 4 will slowly separate from the strip alloy under the restriction of the moving device 3. Until the last locking piece 4 separates from the strip alloy, the last locking piece 4 is completely reset. The welded strip alloy is released through a phased and gradual unlocking method. The close contact state of the first locking piece 4 provides partial constraint. The subsequent locking pieces 4 gradually separate, allowing the strip alloy to slowly adapt to stress changes and maintain stability. When the last locking piece 4 is completely reset, the strip alloy is in a near-free state. At this time, most of the residual stress has been released, reducing the risk of strip alloy deformation.
[0025] The method of use and advantages of this invention: The working process of this strip alloy electron beam welding device is as follows: like Figures 1 to 12 As shown, a strip of alloy is wrapped around a cylindrical part. A rotary motor 11 drives a rotating rod 21 to rotate. The rotation of the rotating rod 21 causes the active cone disk 22 to rotate. When the active cone disk 22 rotates, it causes the driven cone disk 25 to rotate through a connecting belt 26. The connecting belt 26 is forced to run at different radii of the active cone disk 22 and the driven cone disk 25. The rotational speed of the driven cone disk 25 is less than that of the active cone disk 22. The rotational speed of the rotating rod 24 slows down. The slow rotation of the rotating rod 24 drives the rotating gear 27 to cause the gear ring 29 to drive the rotating disk 28 to rotate slowly. When the rotating disk 28 rotates, it will drive the adjusting disk 31 to rotate. The several inclined grooves 32 opened on the adjusting disk 31 will drive the moving rod 33 on the support sleeve 1 to slide on the support sleeve 1. The moving rod 33 will drive the moving plate 34 to move towards the strip alloy. At this time, the moving plate 34 will abut against the outer wall of the locking frame 41, thereby driving the locking frame 41 to move towards the strip alloy synchronously. When it moves to the lock opening 43, the inclined surface of the inclined block 44 set on the locking frame 41 will abut against the outer wall of the lock opening 43. When the wedge-shaped plate 410 on the locking frame 41 extends into the wedge-shaped groove 49 on the push rod 46, the push rod 46 is driven by the wedge-shaped surface to drive the positioning frame 48 to abut against the strip alloy, and the cylindrical part is installed on the fixed sleeve 12. When the rotating rod 21 rotates in the reverse direction, the reverse rotation of the connecting rod 51 will not drive the one-way shaft to rotate. The rotating helical gear 56, which is mounted on the one-way shaft, will remain stationary on the support plate 55. When the connecting rod 51 drives the rotating frame 52 to rotate in the reverse direction, since the rotating helical gear 56 is stationary, the transmission helical gear 58, driven by the rotating frame 52, will rotate around the connecting rod 51 under the constraint of the rotating helical gear 56. At this time, the rotation of the rotating helical gear 56 will drive the transmission rod 57 to rotate. The eccentric turntable 59, which is eccentrically set on the transmission rod 57, will rotate. The eccentric turntable 59 drives the eccentric frame 510 to move. The eccentric frame 510 will drive the unlocking frame 511 to move back and forth on the rotating frame 52. At this time, the unlocking frame 511 moves down and abuts against the inclined locking block 44 at the lock opening 43, causing the inclined locking block 44 to separate from the lock opening 43. When the inclined locking block 44 separates from the lock opening 43, the locking frame 41 will reset under the action of the connecting spring 42, thereby separating the positioning frame 48 that fixes the strip alloy from the strip alloy.
