It is responsible for efficiently transmitting the torque and rotational motion transmitted from the transmission to the main reducer of the rear axle, thereby driving the wheels to rotate and enabling the vehicle to drive smoothly. Among them, the hollow tube is an important part of the high-speed drive shaft. Its primary function is to carry the torque and rotational motion transmitted from the transmission and efficiently transmit it to the main reducer of the rear axle. During production, connectors for assembling other components of the drive shaft need to be welded at both ends of the hollow tube. However, welding defects such as pores, slag inclusions, and lack of fusion are likely to occur during the hollow tube welding process.

Detailed implementation manners

[0018] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings.

[0019] Refer to Figures 1-3, the present invention provides a hollow tube welding detection device for a high-speed transmission shaft, which includes two support rod assemblies 1. A conveying device 2 is arranged at the top of the support rod assembly 1. The two sides of the conveying device 2 are fixedly connected with a machine shell 3. The conveying device 2 includes a top box 21 and a conveyor belt 22. The conveyor belt 22 is fixedly installed at the bottom of the top box 21. A number of clamping and detecting components 4 are symmetrically arranged on both sides of the top box 21. A number of lifting arm components 5 are installed inside the top box 21. The lifting arm components 5 are used to control the lifting of the clamping and detecting components 4 on both sides of the conveying device 2; The clamping and detecting component 4 is used for hollow tube welding detection and hollow tube position deviation correction; The clamping and detecting component 4 includes a V-shaped clamping plate 41. A regulating component 42 is fixedly installed at the top of the V-shaped clamping plate 41. A detecting head 44 is installed on one side of the regulating component 42 through a connecting plate 43. The detecting head 44 is electrically connected to a detecting device through an electric wire. A hole penetrating into the V-shaped groove is opened at the top of the V-shaped clamping plate 41; The regulating component 42 is used to control the rotation of the hollow tube.

[0020] During use, the hollow tube to be detected is placed on the tops of the two support rod assemblies 1. Since the conveying device 2 is located above the support rod assembly 1, the operation of the conveyor belt 22 of the conveying device 2 in contact with the top of the hollow tube can make the hollow tube roll on the tops of the support rod assemblies 1, thereby achieving the effect of hollow tube conveying. When the hollow tube reaches the bottom of the clamping and detecting component 4, the lifting arm component 5 operates to move the clamping and detecting components 4 symmetrically on both sides of the support rod assembly 1 downward to clamp and fix the hollow tube, and make the detecting end reach the detecting position. According to the structural setting of the clamping and detecting component 4, during the downward movement, the hollow tube enters the V-shaped groove of the V-shaped clamping plate 41. According to its shape characteristics, the axis of the hollow tube can be limited to the symmetry line of the V-shaped groove, thus achieving the effect of position deviation correction and avoiding the deviation of the hollow tube during conveying, and the welding position deviating from the detection range of the detecting head 44. During the detection process, the regulating component 42 operates to probe into the V-shaped groove through the hole at the top of the V-shaped clamping plate 41 to contact the hollow tube, and drives the hollow tube to rotate, so that the detecting head 44 can detect the annular weld; Since there are a number of clamping and detecting components 4 on both sides of the support rod assembly 1, multi-station detection can be carried out, and a number of lifting arm components 5 can be triggered to operate in sequence from back to front.

[0021] Refer to Figure 3 , the detecting device includes but is not limited to: one of an ultrasonic flaw detector and a radiographic inspection device. The ultrasonic flaw detector and the radiographic inspection device can effectively detect welding defects generated during the welding process of the hollow tube, such as pores, slag inclusions, lack of fusion, etc.

[0022] Refer to Figure 2, further comprising a control system for controlling the operation of the lifting arm assembly 5, the clamping pressure detection assembly 4 and the conveyor belt 22. A position sensor 6 penetrating to the bottom is installed inside the top box 21. A plurality of position sensors 6 are provided and are all electrically connected to the control system. The plurality of position sensors 6 are respectively horizontally aligned with a plurality of clamping pressure detection assemblies 4 on both sides of the support rod assembly 1. By providing the position sensor 6, the position of the hollow tube at the top of the support rod assembly 1 can be detected, facilitating the clamping pressure detection assembly 4 to align with the hollow tube and clamp it tightly.

[0023] Refer to Figure 4 , the lifting arm assembly 5 includes a fixed frame 51 and a first motor 53. A threaded column 52 is rotatably sleeved at the top of the fixed frame 51. A moving sleeve 54 is threadedly sleeved on the side wall of the threaded column 52. The back end of the moving sleeve 54 is fixedly connected to a main body arm 55. The output shaft of the first motor 53 is fixedly connected to the bottom end of the threaded column 52. A plurality of sliding grooves are formed on both sides of the top box 21. Both ends of the main body arm 55 pass through the sliding grooves and are connected to the clamping pressure detection assembly 4. By driving the threaded column 52 to rotate by the output power of the first motor 53, the moving sleeve 54 is controlled to lift under the action of the spiral structure. Under the connection effect of the main body arm 55, the lifting arm assembly 5 controls the lifting of the clamping pressure detection assembly 4.

[0024] Refer to Figure 5 , the regulation component 42 includes a cylinder shell 45 and a caster assembly 46. A rotary power mechanism 47 and a lifting power mechanism 48 are arranged inside the cylinder shell 45. The output ends of the rotary power mechanism 47 and the lifting power mechanism 48 are docked with the caster assembly 46. The rotary power mechanism 47 is used to control the rotation of the rollers of the caster assembly 46, and the lifting power mechanism 48 is used to control the lifting of the caster assembly 46. When detecting the hollow tube, the lifting power mechanism 48 operates to drive the caster assembly 46 to move down and contact the hollow tube. The rotary power mechanism 47 drives the caster assembly 46 to operate to make its rollers rotate. Under the influence of friction, the hollow tube rotates automatically, so as to facilitate the detection head 44 to detect the welding part in all directions and avoid detection blind spots.

[0025] Refer to Figure 6, the caster assembly 46 includes a caster frame 461. A roller body 462 is rotatably sleeved on the inner wall of the caster frame 461. A column 463 is fixedly connected to the top of the caster frame 461. A bevel gear disk 464 is rotatably sleeved on the side wall of the column 463. A bevel gear 465 is connected to the side wall of the column 463 through a rotating shaft. The bevel gear disk 464 meshes with the bevel gear 465. One end of the roller body 462 is drivingly connected to the bevel gear 465 through a belt pulley drive assembly 466. The output end of the rotation power mechanism 47 is fixedly connected to the top of the bevel gear disk 464. The top end of the column 463 is fixedly connected to the output end of the lifting power mechanism 48. By the rotation power output by the rotation power mechanism 47 driving the bevel gear disk 464 to rotate, due to the meshing relationship between the bevel gear disk 464 and the bevel gear 465 and the driving effect of the belt pulley drive assembly 466, the roller body 462 can be rotated. And by the output of the lifting power mechanism 48 driving the column 463 to move up and down, the entire caster assembly 46 can be lifted and lowered.

[0026] Refer to Figure 7 , the rotation power mechanism 47 includes an outer rotating cylinder 471 and a second motor 474. An inner rotating cylinder 472 is slidably sleeved in the inner cavity of the outer rotating cylinder 471. An anti - detachment groove is formed on the side wall of the inner rotating cylinder 472. A clamping block 476 is slidably sleeved in the anti - detachment groove. The clamping block 476 is fixedly connected to the inner wall of the outer rotating cylinder 471. A first toothed ring 473 is fixedly connected to the top end of the outer rotating cylinder 471. The second motor 474 is fixedly installed on the side wall of the cylinder shell 45. A first gear 475 is fixedly installed on the output shaft of the second motor 474. The first gear 475 meshes with the first toothed ring 473. A positioning ring is fixedly connected to the inner wall of the cylinder shell 45. An annular groove is formed on the side wall of the outer rotating cylinder 471. The positioning ring on the inner wall of the cylinder shell 45 is movably sleeved in the annular groove. By the power output of the second motor 474 driving the first gear 475 to rotate, due to the meshing relationship between the first gear 475 and the first toothed ring 473, the outer rotating cylinder 471 rotates. By setting the cooperation between the clamping block 476 and the anti - detachment groove, while preventing the inner rotating cylinder 472 from falling off from the inside of the outer rotating cylinder 471, the outer rotating cylinder 471 can also drive the inner rotating cylinder 472 to rotate, so that the rotation power mechanism 47 outputs rotation power. And through this structural setting, it can be avoided that the rotation power mechanism 47 interferes with the lifting of the caster assembly 46.

[0027] Refer to Figure 8 , the lifting power mechanism 48 includes an outer layer cylinder 481. A polygonal inner cylinder 482 is slidably sleeved in the inner cavity of the outer layer cylinder 481. A screw rod 483 is threadedly sleeved in the inner cavity of the polygonal inner cylinder 482. A third motor 485 is fixedly installed at the top end of the outer layer cylinder 481. The output end of the third motor 485 penetrates the outer layer cylinder 481 and is connected to the screw rod 483. The bottom end of the polygonal inner cylinder 482 is connected to the caster assembly 46. A top disk 484 is arranged on the top of the cylinder shell 45. By the power output of the third motor 485 driving the screw rod 483 to rotate, under the action of the thread structure, the polygonal inner cylinder 482 slides in the inner cavity of the outer layer cylinder 481, thereby controlling the lifting of the caster assembly 46.

[0028] Reference Figure 8 Moreover, the lifting power mechanism 48 further includes a self-locking motor 488. An annular rail groove is provided on the side wall of the top plate 484. A plurality of ear plates 486 are slidably sleeved in the annular rail groove. The plurality of ear plates 486 are fixedly connected to the side wall of the cylinder shell 45. The self-locking motor 488 is fixedly installed on the side wall of the cylinder shell 45. A second gear 489 is fixedly connected to the output shaft of the self-locking motor 488. A second toothed ring 487 is engaged with the side wall of the second gear 489. The second toothed ring 487 is fixedly connected to the top of the top plate 484. The self-locking motor 488 outputs power to drive the second gear 489 to rotate. Under the meshing action of the second gear 489 and the second toothed ring 487, the second toothed ring 487 drives the top plate 484 to rotate. The outer cylinder 481 drives the polygonal inner cylinder 482 to rotate, so as to adjust the angle of the caster assembly 46. When the caster assembly 46 rotates 90° for operation, the axial displacement of the hollow tube can be realized, so as to further correct the deviation of the hollow tube. In addition, due to the self-locking characteristic of the self-locking motor 488, when the self-locking motor 488 does not operate, it locks the angle of the caster assembly 46, avoiding the change of the angle of the caster assembly 46 when the rotation power mechanism 47 outputs a rotational force. The model of the self-locking motor 488 is: LS57A20-D2B30S02.

[0029] Reference Figure 9 Moreover, the bottom of the support rod assembly 1 is installed on the ground through a telescopic mechanism. The support rod assembly 1 includes a main rod 11. Rotating holes are provided at both ends of the main rod 11. End frames 12 are provided at both ends of the main rod 11. Inner side surfaces of the two end frames 12 are fixedly connected with end shafts 13. The two end shafts 13 are rotatably sleeved in the rotating holes at both ends of the main rod 11 respectively. When the axial displacement and rotational adjustment of the hollow tube are controlled by the caster assembly 46, the hollow tube will generate frictional force with the conveyor belt 22 and the support rod assembly 1. By providing the telescopic mechanism, the height of the support rod assembly 1 can be adjusted, so that the hollow tube does not contact the conveyor belt 22 to reduce the interference of the frictional force. And through the structural setting of the support rod assembly 1, when the hollow tube is axially adjusted, the main rod 11 rotates, thereby reducing the interference of the frictional force during the axial adjustment of the hollow tube.
