When the tooth plate 508 is moved by force, the tooth plate 508 will move along the second slide rail 505 through the connection of the second slider 506, that is, the second slider 506 and the second slide rail 505 are used in cooperation to support and limit the movement of the tooth plate 508, and the movement of the tooth plate 508 can synchronously drive the two inner The push plate 509 moves toward the inner wall of the tube body 208, so that the inner push plate 509 moves to a position that fits the inner wall of the tube body 208. When the two inner push plates 509 are displaced, the inner push plate 509 will drive the insertion rod 512 on one side to move, so that the insertion rod 512 is inserted and moved on the inner wall of the sleeve rod 511 on the other side. That is, the cooperation of the insertion rod 512 and the sleeve rod 511 can support and limit the movement of the two inner push plates 509, so that the use position of the two inner push plates 509 is relatively stable. The inner push plate 509 and the ball 510 are both made of magnetic material, and the inner push plate 509 and the ball 510 are in an attractive state. Moreover, by setting a plurality of balls 510 on the surface of the inner push plate 509, when the inner push plate 509 is in a fit state with the inner wall of the tube body 208,The rotation of the ball bearing 510 can play a role of sliding support, so that the inner push plate 509 can fit the inner wall of the support tube 208 and slide easily. After the magnetic plate 403 on the outside of the tube 208 and the inner push plate 509 on the inside of the tube 208 are in a state of clamping the tube 208, the magnetic plate 403 and the inner push plate 509 are in an adsorption state. At the same time, through the use of multiple third laser rangefinders 520 on the outside of the rotating seat 519, the laser signal emitted by the third laser rangefinder 520 is irradiated on the inner wall of the tube 208, so that the distance from the center line to the inner wall of the tube 208 can be obtained based on the rotating seat 519. If the distance data obtained by the multiple third laser rangefinders 520 are different, it means that the tube 20 8 has defects on its inner wall. When measuring, the first motor 202 is started to drive the driving screw 203 to rotate. The rotation of the driving screw 203 can drive the sliding seat 204 to follow the movement. The sliding seat 204 can drive the bracket 301 to follow the movement. The bracket 301 will move along the first slide rail 205 through the connection with the first slider 302. That is, the first slide rail 205 and the first slider 302 are used in conjunction to support and limit the movement of the bracket 301. Through the movement of the bracket 301, the magnetic suction plates 403 on both sides can be synchronously driven to move toward the other end of the tube body 208. At this time, the magnetic suction plates 403 can drive the measuring component 5 as a whole to move from one end of the tube body 208 to the other end through the adsorption force with the inner push plate 509. At this time, the third laser rangefinder 520 can completely cover the inner wall of the pipe body 208 to achieve comprehensive inner diameter measurement. When the third laser rangefinder 520 moves and measures, the fifth motor 513 is started to drive the second gear 515 to follow the rotation through the connection with the second rotating shaft 514. The second gear 515 drives the rotating seat 519 to rotate through the engagement with the third gear 521. Under the reciprocating forward and reverse rotation of the rotating seat 519, the third laser rangefinder 520 can be driven to rotate and move, completely covering the inner wall of the pipe body 208 to achieve comprehensive inner diameter measurement. By setting the measuring component 5 on the inner wall of the pipe body 208 and the magnetic suction plate 403 on the outside of the pipe 208 to provide magnetic attraction to drive it to move, the measuring device can adapt to any length. The inner diameter of the tube body 208 is measured in a covered manner, which is highly practical. While the inner diameter is measured during the movement of the measuring component 5, the second laser rangefinders 405 on both sides can measure the outer walls of the symmetrical outer walls of the tube body 208 through the avoidance grooves 404. At the same time, when the bracket 301 moves, it will drive the first laser rangefinder 309 to follow the movement. The first laser rangefinder 309 can measure the bottom of the tube body 208 through the slot 207, thereby achieving measurement of multiple positions on the outer wall of the tube body 208, improving the detection position of the detection device, and further improving the accuracy of the detection result. After completing the measurement operation on the tube body, the electric push rod is started to retract and drive the splint to move up and reset, and then the second motor is started to drive the conveyor belt to operate.At this time, the pipe body can be sent out from the inlet and outlet holes on the other side through the operation of the conveyor belt, achieving the purpose of automatically sending out the pipe body after the inspection is completed.
