Description

Technical Field

[0001] This invention relates to the field of crane sprocket welding technology, specifically to a crane sprocket welding processing equipment. Background Technology

[0002] In the manufacturing process of lifting sprockets, the welding connection between the sprocket gear ring and the sprocket hub is a critical processing step. Traditional welding methods typically employ a fixed welding equipment and rotating workpiece operation mode. That is, the workpiece rotates under the drive of a rotary mechanism, while the welding torch remains stationary and performs welding on the circumferential weld. To ensure the positional accuracy and welding stability of the workpiece during rotation, reliable clamping and positioning are required. In existing technologies, clamping such rotating welded workpieces generally relies on manual operation. Operators use multiple discretely arranged moving clamping points to individually place and lock the end face and inner circumferential wall of the workpiece. This manual clamping method not only depends on the operator's experience and skill, but also suffers from a lack of unified coordination in the arrangement and adjustment of clamping points, resulting in low clamping efficiency, uneven clamping force distribution, and difficulty in meeting the demands of mass production and high efficiency.

[0003] More importantly, during the rotational welding of the sprocket gear ring and the hub, the workpiece must simultaneously withstand the circumferential rotational driving force and the thermal stress generated by the welding heat input. This places higher demands on the reliability and coordination of clamping. The workpiece needs axial constraint in the end face direction to prevent movement, and radial support in the inner circumferential wall direction to ensure rotational concentricity. However, in existing manual clamping methods, the end face clamping point and the inner circumferential wall clamping point are independent and operated separately. It is difficult for operators to quickly and coordinately place multiple clamping points at different locations within a limited operating space. This clamping operation mode makes it impossible for the clamping actions in the end face and inner wall directions to be coordinated, which not only prolongs the clamping auxiliary time, but also easily leads to workpiece positioning deviation due to inconsistent locking sequence and force of each clamping point, thus affecting the uniformity and quality consistency of the circumferential weld. With the increasing demand for automated and intelligent welding equipment in the intelligent equipment manufacturing industry, the existing manual point-by-point clamping method has clearly lagged behind the pace of industrial upgrading. There is an urgent need to develop an automated clamping device that can simultaneously clamp the end face and inner wall of the workpiece. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a welding processing device for lifting sprockets, which solves the problems of existing sprocket welding clamping operations where the clamping actions in both the end face and inner wall directions cannot be coordinated and that the clamping points need to be changed during the welding process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding processing device for lifting sprockets, comprising a welding robot, wherein a worktable is provided at the outer end of the welding robot, and a sprocket gear ring and a sprocket hub are provided on the worktable; further comprising: a circumferential limiting component, wherein the circumferential limiting component comprises a plurality of evenly distributed clamping plates, the clamping plates being responsible for abutting and limiting the inner wall of the sprocket hub by moving outward; and an end-face limiting component, wherein the end-face limiting component comprises a plurality of first movable shafts and second movable shafts, wherein a first pressure ring is fixedly sleeved on the outside of the first movable shaft, and a second pressure ring is fixedly sleeved on the outside of the first movable shaft, wherein the first pressure ring or the second pressure ring... The downward movement is achieved by the outer wall abutting against the end face of the sprocket hub to achieve end face limitation; the adjustment component is responsible for driving the clamping plate to move outward and the first or second pressure ring to move downward; the driving component includes a driving source, which is responsible for driving the clamping plate to slowly rotate with the sprocket hub; the alternating limiting component includes a fixed plate disposed near the clamping plate, and multiple first and second movable shafts are rotatably disposed on the fixed plate. The first and second pressure rings are initially misaligned. During the rotation of the clamping plate, the first and second movable shafts rotate, so that the first and second pressure rings alternately abut against the sprocket hub for limitation.

[0006] Preferably, the peripheral limiting component includes a hollow plate, and a support plate is fixedly connected to the outer end of the hollow plate. The support plate is fixedly connected to the clamping plate.

[0007] Preferably, the driving component includes a driving disk, the driving source is a geared motor, the output end of the geared motor is fixedly connected to the driving disk, and a control box is fixedly connected to the top of the driving disk.

[0008] Preferably, the control box is provided with a first adjusting screw, and a threaded sleeve is threaded onto the first adjusting screw. A connecting plate is fixedly connected between the threaded sleeve and the hollow plate.

[0009] Preferably, the alternating limiting component further includes a movable block, a guide groove is provided on the fixed plate, the movable block is slidably connected to the inner wall of the guide groove, a threaded groove is provided on the movable block, and a second adjusting screw is threadedly connected in the threaded groove, the second adjusting screw movably extending to the bottom of the fixed plate.

[0010] Preferably, the adjusting component includes a drive shaft, on which a drive gear is fixedly sleeved, and the drive disk has multiple driven gears inside, which mesh together with the outer edge of the drive gear.

[0011] Preferably, a driven shaft is fixedly connected inside the first adjusting screw, a first bevel gear is fixedly sleeved at one end of the driven shaft, and the other end of the driven shaft is connected to the driven gear. A second bevel gear is fixedly sleeved at the bottom of the second adjusting screw, and the first bevel gear and the second bevel gear are meshed together.

[0012] Preferably, the end face of the clamping plate is provided with a pressure compensation component, the pressure compensation component includes a bonding plate, the bonding plate is made of soft metal material and is responsible for bonding the sprocket hub, a pressure plate is fixedly connected to one side of the bonding plate, a pressure member is fixedly connected inside the clamping plate, and the pressure member is fixedly connected to the pressure plate.

[0013] Preferably, the drive disc is slidably provided with a plurality of evenly distributed locking pins, which are responsible for limiting the sprocket gear ring.

[0014] Preferably, the drive disk has multiple vertical shafts slidably connected to it, each vertical shaft having a shaft hole, and the outer ends of the first and second movable shafts are fixedly connected with insert rods, the insert rods being adapted to the shaft holes.

[0015] This invention provides a welding and processing device for lifting sprockets. It has the following beneficial effects: 1. This invention sets up a peripheral limiting component and uses the rotation of the first adjusting screw to make the hollow plate, along with the fixing plate and the first or second pressure ring, move outward, ultimately achieving the purpose of the clamping plate also moving outward, thereby abutting and limiting the inner wall of the workpiece and effectively preventing it from rotating and shifting during rotational welding.

[0016] 2. By setting an end face limiting component, the second adjusting screw rotates to drive the moving block to descend, thereby bringing the first and second pressure rings down. The first or second pressure rings are used to abut and limit the top of the workpiece, thereby effectively preventing the workpiece from shaking or even jumping in a local area due to multiple forces and centrifugal force during rotation.

[0017] 3. By setting adjustment components, the driving gear drives the driven gear to rotate, and the driven gear drives the driven shaft to rotate. This not only drives the first adjusting screw to rotate, realizing the outward movement and contact of the clamping plate, but also drives the second bevel gear to rotate through the first bevel gear, which in turn drives the second adjusting screw to rotate, realizing the downward movement and contact of the first or second pressure ring. Furthermore, the driving gear drives multiple driven gears to rotate, so that by simply rotating the driving gear, multi-dimensional and multi-faceted limiting and clamping of the workpiece can be achieved simultaneously, making it more convenient to use.

[0018] 4. By setting a rotatable first or second pressure ring, under the action of friction, the first and second pressure rings automatically rotate and alternately squeeze the sprocket hub. When the first pressure ring squeezes the sprocket hub and fixes its end face, the second pressure ring enters a relaxed state and no longer bears the supporting force from the sprocket hub. This ensures that the sprocket hub will not jump during rotation and also effectively controls the force application time of the first and second pressure rings, extending their service life.

[0021] 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.

[0022] Example: Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a welding processing device for a lifting sprocket, including a welding robot 1. A worktable 2 is provided at the outer end of the welding robot 1, and a sprocket gear ring 9 and a sprocket hub 10 are provided on the worktable 2. The device also includes: a peripheral limiting component 3, which includes multiple evenly distributed clamping plates 31. The clamping plates 31 are responsible for abutting and limiting the inner wall of the sprocket hub 10 by moving outwards; and an end limiting component 4, which includes multiple first movable shafts 41 and second movable shafts 42. A first pressure ring 43 is fixedly sleeved on the outside of the first movable shaft 41, and a second pressure ring 44 is fixedly sleeved on the outside of the first movable shaft 41. The first pressure ring 43 or the second pressure ring 44 moves downwards and abuts against the end face of the sprocket hub 10 through its outer wall. The clamping plate 31 is moved outward and the first pressure ring 43 or the second pressure ring 44 is moved downward. The adjusting component 5 is responsible for driving the clamping plate 31 to move outward and the first pressure ring 43 or the second pressure ring 44 to move downward. The driving component 6 includes a driving source 62, which is responsible for driving the clamping plate 31 to rotate slowly with the sprocket hub 10. The alternating limiting component 7 includes a fixed plate 71 set on the clamping plate 31. Multiple first movable shafts 41 and second movable shafts 42 are rotatably connected to the fixed plate 71. The first pressure ring 43 and the second pressure ring 44 are initially misaligned. During the rotation of the clamping plate 31, the first movable shafts 41 and the second movable shafts 42 rotate, so that the first pressure ring 43 and the second pressure ring 44 alternately contact and limit the sprocket hub 10.

[0023] Specifically, the bottom of the welding robot 1 is provided with a base, and the worktable 2 is fixedly connected to the base of the welding robot 1. The welding robot 1 is provided with a welding gun. Before welding, the welding gun moves to the annular gap between the sprocket gear ring 9 and the sprocket hub 10, and then remains stationary. The sprocket gear ring 9 and the sprocket hub 10 rotate slowly to achieve welding between the sprocket gear ring 9 and the sprocket hub 10.

[0024] This design includes three first pressure rings 43 and two second pressure rings 44, which are semi-circular and can be covered with elastic silicone to increase the contact area with the sprocket hub 10. Since the three first pressure rings 43 and the three second pressure rings 44 face opposite directions, when the first pressure rings 43 are in contact with the sprocket hub 10, the second pressure rings 44 are not in contact with the sprocket hub 10. Thus, during the compression process of the first pressure rings 43, the second pressure rings 44 do not compress the sprocket hub 10, which reduces the stress time by half. This ensures that the first pressure rings 43 and the second pressure rings 44 will not be compressed for a long time, which could lead to an upward tilting tendency, thereby extending the service life of the first pressure rings 43 and the second pressure rings 44.

[0025] Please see the appendix Figure 5 -See Figure 6. The peripheral limiting component 3 includes a hollow plate 32. A support plate 33 is fixedly connected to the outer end of the hollow plate 32. The support plate 33 is fixedly connected to the clamping plate 31.

[0026] The drive component 6 includes a drive disk 61, a drive source 62 is a geared motor, the output end of the geared motor is fixedly connected to the drive disk 61, and a control box 63 is fixedly connected to the top of the drive disk 61.

[0027] Specifically, the drive disk 61 is rotatably connected to the worktable 2, the housing of the geared motor is fixedly connected to the bottom of the worktable 2, the output end of the geared motor moves through the worktable 2 and is connected to the drive disk 61, and a control box 63 is connected to the drive disk 61. The control box 63 is hollow inside. When working, the geared motor is turned on, driving the drive disk 61 to rotate. The drive disk 61 will also rotate the sprocket hub 10 through the peripheral limiting component 3 and the end limiting component 4.

[0028] The control box 63 is equipped with a first adjusting screw 51. A threaded sleeve 52 is connected to the first adjusting screw 51. A connecting plate 53 is fixedly connected between the threaded sleeve 52 and the hollow plate 32.

[0029] The first adjusting screw 51 and the threaded sleeve 52 are threadedly connected, so that when the first adjusting screw 51 rotates, it drives the threaded sleeve 52 to move. The threaded sleeve 52 moves the hollow plate 32 through a pair of connecting plates 53.

[0030] Please see the appendix Figure 5 - Appendix Figure 7 The end face limiting component 4 includes a moving block 72, a guide groove 54 is provided on the fixed plate 71, the moving block 72 is slidably connected to the inner wall of the guide groove 54, a threaded groove is provided on the moving block 72, and a second adjusting screw 55 is threadedly connected in the threaded groove, and the second adjusting screw 55 moves through to the bottom of the fixed plate 71.

[0031] Specifically, the fixed plate 71 is fixedly connected to the top surface of the hollow plate 32, and the bottom of the second adjusting screw 55 extends into the interior of the hollow plate 32 and is rotatably connected to the inner bottom surface of the hollow plate 32. The first movable shaft 41 and the second movable shaft 42 are both rotatably connected to the outside of the moving block 72. When the second adjusting screw 55 rotates, due to the threaded connection between the second adjusting screw 55 and the moving block 72, the moving block 72 will move along with it. The moving block 72 moves along with the first pressure ring 43 and the second pressure ring 44 through the first movable shaft 41 and the second movable shaft 42.

[0032] The adjusting component 5 includes a drive shaft 56, on which a drive gear 57 is fixedly sleeved. The drive disk 61 has multiple driven gears 58 inside, and the multiple driven gears 58 mesh together with the outer edge of the drive gear 57.

[0033] The drive shaft 56 extends to the top surface of the control box 63. Anti-slip texture is provided on the outer wall of the drive shaft 56 near the top. By rotating the drive shaft 56, it drives the drive gear 57, which in turn drives the six driven gears 58 that are meshed with it to rotate slowly.

[0034] The first adjusting screw 51 is internally fixedly connected to a driven shaft 59. One end of the driven shaft 59 is fixedly sleeved with a first bevel gear 510, and the other end of the driven shaft 59 is connected to a driven gear 58. The bottom of the second adjusting screw 55 is fixedly sleeved with a second bevel gear 511, and the first bevel gear 510 and the second bevel gear 511 are meshed together.

[0035] Specifically, the gear ratio of the first bevel gear 510 to the second bevel gear 511 is 1:1.5-3. The gear ratio is adjusted according to actual needs so that the moving distance of the clamping plate 31 is greater than that of the first pressure ring 43 or the second pressure ring 44.

[0036] Specifically, a support column is movably sleeved on the driven gear 58, which is responsible for supporting the driven gear 58 and the driven shaft 59. When the driven gear 58 rotates, the driven shaft 59 and the first adjusting screw 51 rotate simultaneously. On the one hand, the driven shaft 59 drives the first bevel gear 510 to rotate, causing the first bevel gear 510 and the second bevel gear 511 to rotate, which in turn causes the second adjusting screw 55 to rotate, thereby adjusting the height of the first pressure ring 43 and the second pressure ring 44. On the other hand, it drives the first adjusting screw 51 to rotate, causing the hollow plate 32 to move along with the fixed plate 71 and the first pressure ring 43 or the second pressure ring 44, ultimately achieving the movement adjustment of the clamping plate 31.

[0037] Optionally, please refer to the appendix. Figure 8The end face of the clamping plate 31 is provided with a pressure compensation component 8. The pressure compensation component 8 includes a bonding plate 81. The bonding plate 81 is made of soft metal material and is responsible for bonding the sprocket hub 10. A pressure plate 82 is fixedly connected to one side of the bonding plate 81. A pressure component 83 is fixedly connected inside the clamping plate 31. The pressure component 83 is fixedly connected to the pressure plate 82.

[0038] The pressure component 83 is a pressure spring. When the bonding plate 81 approaches the sprocket hub 10, the first pressure ring 43 or the second pressure ring 44 has not yet fully squeezed the sprocket hub 10. The drive shaft 56 can continue to rotate, so that the pressure component 83 is squeezed and the clamping plate 31 can continue to move outward a small distance.

[0039] Preferably, a plurality of evenly distributed locking pins are slidably arranged on the drive disc 61, and the locking pins are responsible for limiting the sprocket gear ring 9.

[0040] Specifically, a locking pin is slidably connected to the drive disc 61 via a limiting groove. When the locking pin moves, it enters the locking teeth of the sprocket ring 9, thereby preventing it from rotating off-center.

[0041] The working process in this case is as follows: Preparation: First, place the sprocket gear ring 9 and sprocket hub 10 on the drive disc 61, close the sprocket gear ring 9 and sprocket hub 10 together, and before welding, move the welding gun to the annular gap between the sprocket gear ring 9 and sprocket hub 10, and wait for subsequent welding. Adjustment process: The operator rotates the drive shaft 56, causing it to drive the drive gear 57. The drive gear 57, in turn, slowly rotates the six driven gears 58 connected to it. As the driven gears 58 rotate, the driven shaft 59 and the first adjusting screw 51 rotate simultaneously. On one hand, the driven shaft 59 drives the first bevel gear 510 to rotate, causing the first bevel gear 510 and the second bevel gear 511 to rotate, which in turn causes the second adjusting screw 55 to rotate, and the first pressure ring 43 and the second pressure ring 44 to begin to descend. On the other hand, the rotation of the first adjusting screw 51 causes the hollow plate 32 to carry the fixed plate 71. As the first pressure ring 43 or the second pressure ring 44 moves outward, the clamping plate 31 also moves outward. According to the aforementioned gear ratio, the distance the clamping plate 31 moves is greater than the distance the first pressure ring 43 and the second pressure ring 44 descend, making the device more in line with actual operation. Even if there is a difference in movement, the pressure member 83 can be set so that when the contact plate 81 approaches the sprocket hub 10, the first pressure ring 43 or the second pressure ring 44 has not yet completely squeezed the sprocket hub 10, and the drive shaft 56 can continue to rotate, so that the pressure member 83 is squeezed, and the clamping plate 31 can continue to move outward a small distance. Welding operation: The geared motor is turned on, which drives the drive plate 61 to rotate. The drive plate 61 also rotates the sprocket hub 10 through the clamping plate 31 and the locking pin. Then, the welding torch is controlled to start welding. Since the welding torch is stationary while the sprocket hub 10 starts to rotate, under the action of friction, the first pressure ring 43 and the second pressure ring 44 rotate automatically, alternately squeezing the sprocket hub 10. When the first pressure ring 43 squeezes the sprocket hub 10 and fixes its end face, the second pressure ring 44 enters a relaxed state and no longer bears the supporting force from the sprocket hub 10. This ensures that the sprocket hub 10 does not have an extreme tendency to jump when rotating. At the same time, it effectively controls the force application time of the first pressure ring 43 and the second pressure ring 44, extending their service life. End of work: The subsequent reverse rotation of the drive shaft 56 not only causes the first pressure ring 43 and the second pressure ring 44 to rise, but also moves them inward to make room. Then the welding gun is removed, and the sprocket gear ring 9 and sprocket hub 10 are taken out. For the thicker sprocket gear ring 9 and sprocket hub 10, their reverse sides can be placed directly on the drive disc 61 for welding.

[0042] Optionally, multiple vertical shafts are slidably connected to the drive disk 61, and shaft holes are opened on the vertical shafts. Insert rods are fixedly connected to the outer ends of the first movable shaft 41 and the second movable shaft 42, and the insert rods are adapted to the shaft holes.
