The hollow tube is a crucial component of the high-speed drive shaft. Its primary function is to carry the torque and rotational motion from the transmission and efficiently transmit it to the final reducer on the rear axle.

[0033] Reference Figure 1-Figure 3 The present invention provides a hollow tube welding detection device for a high-speed transmission shaft, comprising two support rod assemblies 1, a conveying device 2 is provided on the top of the support rod assembly 1, and both sides of the conveying device 2 are fixedly connected to an organic shell 3, the conveying device 2 comprises 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 plurality of clamping and pressing detection assemblies 4 are symmetrically provided on both sides of the top box 21, and a plurality of lifting arm assemblies 5 are installed inside the top box 21, and the lifting arm assemblies 5 are used to control the lifting and lowering of the clamping and pressing detection assemblies 4 on both sides of the conveying device 2;

[0034] The clamping and pressing detection component 4 is used for hollow tube welding detection and hollow tube position correction;

[0035] The clamping detection assembly 4 includes a V-shaped clamping plate 41, with a regulating assembly 42 fixedly mounted on the top of the V-shaped clamping plate 41. A detection head 44 is mounted on one side of the regulating assembly 42 via a connecting plate 43. The detection head 44 is electrically connected to the detection device via an electric wire. A hole is opened on the top of the V-shaped clamping plate 41 and penetrates into the V-shaped groove.

[0036] The regulating component 42 is used to control the rotation of the hollow tube.

[0037] When in use, the hollow tube to be tested is placed on the top of the two support rod assemblies 1. Since the conveying device 2 is placed above the support rod assembly 1, the conveyor belt 22 of the conveying device 2 contacts the top of the hollow tube, which can make the hollow tube roll on the top of the support rod assembly 1, thereby achieving the hollow tube conveying effect. When the hollow tube reaches the bottom of the clamping and pressing detection assembly 4, the lifting arm assembly 5 is operated to make the clamping and pressing detection assembly 4 symmetrical on both sides of the support rod assembly 1 move down to press and fix the hollow tube, and make the detection end reach the detection position. According to the structural setting of the clamping and pressing detection assembly 4, during the downward movement, the hollow tube enters the V-shaped clamping plate 41. In the V-shaped groove, the axis of the hollow tube can be limited to the symmetry line of the V-shaped groove according to its shape characteristics, thereby achieving a position correction effect, avoiding the hollow tube from being skewed during transportation, and its welding position deviating from the detection range of the detection head 44. During the detection process, the regulating component 42 runs through the top hole of the V-shaped clamping plate 41 to penetrate into the V-shaped groove and contact the hollow tube, and drives the hollow tube to rotate, so that the detection head 44 can detect the annular weld; since there are a number of clamping detection components 4 on both sides of the support rod component 1, multi-station detection can be performed, and a number of lifting arm components 5 can be triggered to run in sequence from back to front.

[0038] Reference Figure 3 The detection device includes but is not limited to: one of an ultrasonic flaw detector and a radiographic flaw detector.

There are several position sensors 6, and they are all electrically connected to the control system, and several position sensors 6 are horizontally aligned with several clamping and pressing detection assemblies 4 on both sides of the support rod assembly 1. By setting the position sensor 6, the position of the hollow tube on the top of the support rod assembly 1 can be detected, so that the clamping and pressing detection assembly 4 can align with the hollow tube to press it.

[0040] Reference Figure 4 The lifting arm assembly 5 includes a fixed frame 51 and a motor 53.

A number of slide grooves are provided on both sides of the top box 21. The two ends of the main arm 55 pass through the slide grooves and are connected to the clamping and pressing detection assembly 4. The threaded column 52 is driven to rotate by the output power of the motor 53. Under the action of the spiral structure, the movable sleeve 54 is controlled to rise and fall. Under the connection effect of the main arm 55, the lifting arm assembly 5 controls the lifting and falling of the clamping and pressing detection assembly 4.

[0041] Reference Figure 5 The regulating component 42 includes a cylindrical shell 45 and a caster assembly 46. A rotating power mechanism 47 and a lifting power mechanism 48 are provided inside the cylindrical shell 45. The output ends of the rotating power mechanism 47 and the lifting power mechanism 48 are connected to the caster assembly 46. The rotating power mechanism 47 is used to control the rotation of the roller of the caster assembly 46, and the lifting power mechanism 48 is used to control the lifting and lowering of the caster assembly 46. When inspecting the hollow pipe, the lifting power mechanism 48 is used to drive the caster assembly 46 to move down and contact the hollow pipe, and the rotating power mechanism 47 drives the caster assembly 46 to rotate its roller, and the empty pipe is rotated under the influence of friction, so that the detection head 44 can detect the welding position in all directions and avoid blind spots in detection.

The rotating power output by the rotating power mechanism 47 drives the bevel gear 464 to rotate, and the meshing relationship between the bevel gear 464 and the bevel gear 465 and the transmission effect of the pulley transmission assembly 466 can make the roller body 462 rotate, and the output of the lifting power mechanism 48 drives the column 463 to move up and down, so that the caster assembly 46 can be lifted and lowered as a whole.

The second motor 474 is fixedly installed on the side wall of the cylinder shell 45. A gear 475 is fixedly installed on the output shaft of the second motor 474. The gear 475 is meshed with the gear ring 473. A positioning ring is fixedly connected to the inner wall of the cylinder shell 45. The outer rotating cylinder 471 is fixedly connected to the outer rotating cylinder 471. An annular groove is provided on the side wall of 71, and a positioning ring on the inner wall of the cylinder shell 45 is movably sleeved in the annular groove. The power output by the motor 2 474 drives the gear 1 475 to rotate, and the outer rotating cylinder 471 is rotated by the meshing relationship between the gear 1 475 and the gear ring 1 473. By setting a block 476 and cooperating with the anti-slip groove, the outer rotating cylinder 471 can prevent the inner rotating cylinder 472 from falling off from the inside of the outer rotating cylinder 471 while also allowing the outer rotating cylinder 471 to drive the inner rotating cylinder 472 to rotate, so that the rotating power mechanism 47 outputs rotating power. This structural setting can prevent the rotating power mechanism 47 from interfering with the lifting and lowering of the caster assembly 46.

[0044] Reference Figure 8 The lifting power mechanism 48 includes an outer tube 481, the inner cavity of the outer tube 481 is slidably connected to a polygonal inner tube 482, the inner cavity of the polygonal inner tube 482 is threadedly connected to a screw 483, and a motor 3 485 is fixedly installed on the top of the outer tube 481.

The top plate 484 is arranged on the top of the cylinder shell 45. The screw 483 is driven to rotate by the output power of the motor 3 485. Under the action of the threaded structure, the polygonal inner tube 482 slides in the inner cavity of the outer tube 481, thereby controlling the lifting and lowering of the caster assembly 46.

[0045] Reference Figure 8 The lifting power mechanism 48 also includes a self-locking motor 488. The side wall of the top plate 484 is provided with an annular rail groove, and a plurality of ear plates 486 are slidably sleeved in the annular rail groove.

A gear 2 489 is fixedly connected to the output shaft of the self-locking motor 488. A gear ring 2 487 is meshed with the side wall of the gear 2 489. The gear ring 2 487 is fixedly connected to the top of the top plate 484. The power output by the self-locking motor 488 drives the gear 2 489 to rotate. Under the meshing action of the gear 2 489 and the gear ring 2 487, the gear 2 489 is rotated. Ring 2 487 drives the top plate 484 to rotate, and drives the polygonal inner tube 482 to rotate through the outer tube 481, thereby adjusting the angle of the caster assembly 46. When the caster assembly 46 rotates 90°, the hollow tube can be axially displaced, thereby further correcting the hollow tube. In addition, through the self-locking characteristics of the self-locking motor 488, when the self-locking motor 488 is not running, it has the effect of locking the angle of the caster assembly 46, avoiding the angle change of the caster assembly 46 when the rotating power mechanism 47 outputs the rotating force. The model of the self-locking motor 488 is: LS57A20-D2B30S02.

Both ends of the main rod 11 are provided with a rotary hole. Both ends of the main rod 11 are provided with an end frame 12. The inner sides of the two end frames 12 are fixedly connected with an end shaft 13. The two end shafts 13 are respectively rotatably sleeved in the rotary holes at both ends of the main rod 11. When the axial displacement and rotation adjustment of the hollow tube are controlled by the caster assembly 46, the hollow tube will generate friction with the conveyor belt 22 and the support rod assembly 1. By setting the telescopic mechanism, the height of the support rod assembly 1 can be adjusted, so that the hollow tube and the conveyor belt 22 are not in contact, reducing friction interference. The structural setting of the support rod assembly 1 can make the main rod 11 rotate when the hollow tube is axially adjusted, thereby reducing friction interference in the axial adjustment of the hollow tube.
