[0041] The defective lens 3011 is a CCD lens structure, and the top end of the operation table 101 is adsorbed and limited by a magnetic support 4, the magnetic support 4 is a permanent magnet structure, and the inside of the top end of the magnetic support 4 is provided with an annular groove, which is a guide groove 401.

[0042] The inside of the guide groove 401 is rotatably connected with a rotating block 4011, the top end face of the rotating block 4011 is fixedly connected with a screw sleeve assembly 4012, the inside of the screw sleeve assembly 4012 is provided with a screw hole, the inside of the screw hole is screwed with a screw rod assembly 4013, the top end of the screw rod assembly 4013 is fixedly connected with a limiting column 4014, the outer circumferential surface of the limiting column 4014 is provided with a limiting clamping groove 4015, and the inside of the limiting clamping groove 4015 is clamped and limited with a to-be-detected piece 4016.

[0043] Working principle:

[0044] First, complete the fixing operation of the detected piece 4016, place the detected piece 4016 in the limiting card slot 4015 inside the limiting stand column 4014, rotate the screw rod assembly 4013, make it displace longitudinally under the action of the thread structure inside the screw sleeve assembly 4012, and then drive the limiting stand column 4014 to rise and fall synchronously, so as to adapt to different sizes of the detected piece 4016, and ensure that the detected piece 4016 can be tightly clamped. The magnetic support 4 is a permanent magnet structure, which can be adsorbed on the top of the operation table 101 by its own magnetism, so as to realize the basic positioning of the whole fixing structure. If it is necessary to adjust the detection angle of the detected piece 4016, the rotating block 4011 can be rotated to rotate along the annular track of the guide groove 401. The rotation of the rotating block 4011 drives the screw sleeve assembly 4012, the screw rod assembly 4013, the limiting stand column 4014 and the detected piece 4016 to rotate together, until the detected piece 4016 is at the appropriate detection angle position;

[0045] After the fixing of the detected piece 4016 is completed, the internal detection preparation of the equipment can be started. The operator issues an instruction through the control screen of the control terminal 1015. The instruction signal is transmitted to the transmission wire harness 5 through the connecting assembly 1013, and then transmitted to the guide support 6 outside the probe head by the transmission wire harness 5. Four annular array distribution slots are formed on the outer circumferential surface of the guide support 6. The upper and lower slots are both equipped with a servo push rod A601 inside. After receiving the signal, the two servo push rods A601 extend synchronously, push the displacement assembly 6011 to move away from the guide support 6, and then drive the suction cup assembly 6012 at the end of the displacement assembly 6011 to move synchronously until the suction cup assembly 6012 contacts the inner wall of the detected piece 4016. At this time, the electromagnet inside the suction cup assembly 6012 generates magnetism after being electrified, and is adsorbed on the inner wall of the detected piece 4016, realizing the preliminary fixation of the probe head in the detected piece 4016;

[0046] Meanwhile, the two servo push rods B7 inside the two grooves on the left and right sides of the guide support 6 will also receive instructions from the control terminal 1015 and extend outward at the same time, pushing the moving bracket 701 to slide along the groove, and the side plate assembly 7011 is fixed on the side of the moving bracket 701 away from the servo push rod B7, and the upper side plate assembly 7011 is provided with a moving motor 7012 at the top end, and the output shaft of the moving motor 7012 is connected with a stepping wheel 7013, which will gradually contact the inner wall of the to-be-detected piece 4016 with the movement of the moving bracket 701, and the anti-skid groove on the outer circumferential surface of the stepping wheel 7013 can increase the friction with the inner wall of the to-be-detected piece 4016 to avoid slipping, and when the suction cup assembly 6012 and the stepping wheel 7013 are in contact with the inner wall of the to-be-detected piece 4016, the moving motor 7012 is started to drive the stepping wheel 7013 to rotate, and under the action of the rotation of the stepping wheel 7013, the entire detection head moves along the internal passage of the to-be-detected piece 4016, so as to detect the welds on the inner wall at different positions;

[0047] During the movement of the detection head, the auxiliary lamp 501 plays a role of illumination, and the auxiliary lamp 501 is of a ring-shaped LED structure and is fixed on the outer circumferential surface of the detection head, which can provide uniform and sufficient light for the inside of the to-be-detected piece 4016, so as to ensure that the recognition lens 5011 can clearly shoot the weld image, and the recognition lens 5011 is of a CCD lens structure and is fixed on the inclined surface at the end of the detection head in a ring-shaped array, and the design of the inclined surface enables the recognition lens 5011 to cover a larger detection range and can shoot the inner wall welds at different angles, and the image shot by the recognition lens 5011 is transmitted in real time to the control terminal 1015 through the transmission wire harness 5, and the control terminal 1015 processes and displays the image, so as to facilitate the operator to observe the welds on the inner wall of the to-be-detected piece 4016 in real time;

[0048] In addition to internal detection, the platform can also detect the external welds of the to-be-detected piece 4016, and the control box 1 is provided with a servo motor 2 at the left end, and when it is necessary to adjust the transverse position of the external detection structure, the control terminal 1015 sends instructions to the servo motor 2, the servo motor 2 is started and drives the transmission screw 201 to rotate through the shaft coupling, the transmission screw 201 is rotatably connected in the transverse groove at the rear side of the control box 1 through a bearing seat, a moving assembly 2011 is provided with a screw hole matched with the transmission screw 201 inside, and two slide block assemblies 2012 are fixed on the upper and lower sides of the moving assembly 2011, the slide block assemblies 2012 are embedded in the inner wall of the transverse groove and play a guiding role, and when the transmission screw 201 rotates, the moving assembly 2011 slides transversely along the transverse groove under the action of threads, thereby driving the guide frame assembly 2013 at the top end to move transversely at the same time;

[0049] The guide frame assembly 2013 is longitudinally arranged, and a longitudinal slot is formed in the guide frame assembly 2013. A lifting push rod 2014 is mounted in the longitudinal slot. The top end of the lifting push rod 2014 is connected with a longitudinal support 3. When the longitudinal height of the external detection structure needs to be adjusted, the control terminal 1015 controls the lifting push rod 2014 to extend or retract. The lifting push rod 2014 drives the longitudinal support 3 to move along the longitudinal slot. Two guide sliding blocks 301 are fixed to the left and right sides of the longitudinal support 3. The guide sliding blocks 301 are in sliding connection with the inner wall of the longitudinal slot, so that the longitudinal support 3 can be kept stable during movement. A defect lens 3011 is mounted at the bottom end of the longitudinal support 3. The defect lens 3011 is a CCD lens structure. With the movement of the longitudinal support 3, the height and lateral position of the defect lens 3011 are adjusted, so that the external welds at different positions of the workpiece 4016 to be detected can be photographed. The photographed images are transmitted to the control terminal 1015 for processing and display.

[0050] During the entire detection process, the control terminal 1015 is a core control component, which integrates the image information transmitted by the internal identification lens 5011 and the external defect lens 3011. The operator can monitor the detection situation in real time through the control screen and issue corresponding control instructions as needed to realize coordinated control of each component. The two closed box doors 1011 at the front end of the control box 1 can be flexibly opened and closed through the handle 1016, which facilitates the maintenance and maintenance of the components inside the control box 1. The heat dissipation grooves on the closed box doors 1011 can help dissipate heat inside the control box 1, ensuring stable operation of the equipment. The four foot assemblies 1012 at the bottom end of the control box 1 serve as supports to ensure that the entire equipment remains stable during the detection process. The connection assembly 1013 is in an L-shaped structure and is fixed to the top end of the operation table top 101. It is used to connect the transmission wire harness 5 and the support bracket assembly 1014. The bracket assembly 1014 serves as a support for the control terminal 1015, ensuring stable installation of the control terminal 1015.

[0051] Through the cooperative work of the above components, the laser penetration welding defect detection platform can realize comprehensive detection of the internal and external welds of the workpiece 4016 to be detected. Whether it is a straight pipe or a bent pipe structure, the detection platform can accurately capture weld defects through the flexible movement of the probe head and the multi-dimensional adjustment of the detection structure, providing reliable protection for welding quality detection.
