The two servo motors 1302 are symmetrical, and the output shafts of the servo motors 1302 are both equipped with swing arm plates 1303. The lower parts of the two swing arm plates 1303 are connected through a blowpipe 1306, and fixed rods 1308 are installed on the opposite surfaces of the swing arm plates 1303. The fixed rods 1308 are equipped with air pumps 1309, and the air pumps 1309 are connected to the blowpipes 1306. 6 are connected through the air pipe 1310. When the casting core needs to be inspected, the longitudinal guide rail 7 can drive the blowing pipe 1306 on the swing arm plate 1303 to move synchronously through the linkage rod 1301 when moving horizontally.

When the first slide 6 is reset, the driving tooth 1312 rotates counterclockwise, so that the servo motor 1302 drives the swing arm plate 1303 to rotate clockwise under the control of the steering sensor 1313, making it convenient for the blowing pipe 1306 to switch to the front again as the infrared detector 12 is reset, so that the blowing pipe 1306 can be automatically switched according to the moving direction of the infrared detector 12.

[0040] The lower part of the two swing arm plates 1303 is provided with a through hole 1304, and a rotating column 1305 is rotatably installed in the through hole 1304. The two rotating columns 1305 are connected by a blow pipe 1306, and two counterweight blocks 1307 are symmetrically installed at the bottom of the blow pipe 1306. Since the blow pipe 1306 can be rotated by the rotating column 1305, the gravity of the counterweight block 1307 can ensure that the blow pipe 1306 always remains vertically downward.

When the driving tooth 1312 is moving laterally, the driving tooth 1312 can drive the transmission plate 1404 to move synchronously through the slider 1403 during the movement. During the movement, the transmission plate 1404 can drive the transmission column 1407 to rotate through the squeezing force of the spiral track groove 1408 by the driving shaft 1406. During the rotation, the transmission column 1407 can drive the transmission wheel 1412 to rotate synchronously. Through the pulley transmission composed of the transmission wheel 1412, the driven wheel 1409 and the transmission belt 1410, the driven wheel 1409 can drive the worm 1411 to rotate.

[0043] A connecting shaft is rotatably mounted at the center of one side of the driving tooth 1312 close to the main body 1 , and the connecting shaft is connected to the slider 1403 on the same side, so as to prevent the driving tooth 1312 from interlocking with the slider 1403 during movement.

[0044] The detection enhancement assembly 14 includes a reciprocating screw 1413, a turbine 1414, a moving seat 1415, a slide slot 1416, a slide plate 1417, a connecting block 1418, a push-pull plate 1419, a transmission rod 1420, an opening 1421 and an impact rubber head 1422;

[0045] A reciprocating screw 1413 is rotatably mounted on the top of the chamber 1401, a turbine 1414 is mounted on the bottom of the reciprocating screw 1413, the turbine 1414 is meshed with the worm 1411, a moving seat 1415 is slidably mounted on the reciprocating screw 1413, two slide grooves 1416 are symmetrically provided on the top of the chamber 1401, a slide plate 1417 is slidably mounted in each of the two slide grooves 1416, and a connecting block 1418 is mounted on the bottom of the slide plate 1417. The connecting block 1418 is connected to the movable seat 1415 through a push-pull plate 1419. The two ends of the push-pull plate 1419 are respectively hinged to the connecting block 1418 and the movable seat 1415. Transmission rods 1420 are installed on the opposite back surfaces of the two connecting blocks 1418. Two groups of openings 1421 are symmetrically opened on the chamber 1401. The transmission rods 1420 pass through the openings 1421 and are slidably matched. The ends of the transmission rods 1420 are installed with impact rubber heads 1422. When the worm 1411 rotates, the worm 1411 cooperates with the turbine 1414 to drive the reciprocating screw 1413 to rotate, so that the moving seat 1415 can move back and forth vertically along the reciprocating screw 1413. When the moving seat 1415 moves downward, the moving seat 1415 can drive the two slide plates 1417 to move toward each other through the push-pull plate 1419 during the downward movement, so that the connecting block 1418 can drive the impact through the transmission rod 1420. The impact rubber head 1422 vibrates the casting core on the detection position, so that the impurity particles attached to the casting core fall off under the impact of the vibration force, and are conveniently removed under the action of the airflow of the blowing pipe 1306. When the movable seat 1415 moves upward, the two slides 1417 can be driven by the push-pull plate 1419 to move in opposite directions, which is conducive to the resetting of the impact rubber head 1422, and can realize intermittent vibration of the impact rubber head 1422 as the movable seat 1415 moves back and forth vertically.

[0046] Working principle of the present invention:

[0047] When it is necessary to inspect the surface of the casting core, the casting core to be inspected is placed on the clamping table 3, and the casting core on the clamping table 3 is transported to the inspection position of the main body 1 through the conveying track 2. At the same time, starting the transverse guide rail 5 can allow the first slide 6 to drive the longitudinal guide rail 7 to move laterally. Starting the longitudinal guide rail 7 can allow the second slide 8 to drive the arc guide rail 10 to move longitudinally through the electric lifter 9. By starting the electric lifter 9, the infrared detector 12 can be driven to adjust vertically, and by starting the arc guide rail 10, the third slide 11 can drive the infrared detector 12 to adjust the irradiation angle, which is conducive to comprehensive inspection of the casting core through the infrared detector 12, and can improve the detection accuracy.

[0048] When the casting core needs to be inspected, the longitudinal guide rail 7 can drive the blowing pipe 1306 on the swing arm plate 1303 to move synchronously horizontally through the linkage rod 1301 when moving horizontally. At the same time, start the air pump 1309 so that the air pump 1309 can supply air to the blowing pipe 1306 through the air pipe 1310, so that the blowing pipe 1306 can comprehensively blow the casting core at the inspection position during the movement, which is beneficial to remove dust and impurity particles on the surface of the casting core.

[0049] When the first slide 6 moves laterally, the linkage rod 1301 can drive the driving tooth 1312 to move laterally synchronously through the connecting rod 1311 during the movement. Through the meshing action of the driving tooth 1312 and the tooth plate 1314, the driving tooth 1312 can rotate clockwise during the lateral movement. At this time, the steering sensor 1313 can control the operation of the servo motor 1302 during the clockwise rotation, so that the servo motor 1302 drives the swing arm plate 1303 to rotate counterclockwise, which is beneficial for the swing arm plate 1303 to control the blowing pipe 1306 to move to the front of the infrared detector 12. When the first slide 6 is reset, the driving tooth 1312 rotates counterclockwise, so that the servo motor 1302 drives the swing arm plate 1303 to rotate clockwise under the control of the steering sensor 1313, which is convenient for the blowing pipe 1306 to switch to the front again as the infrared detector 12 is reset, so that the blowing pipe 1306 can automatically switch according to the moving direction of the infrared detector 12.

[0050] When the driving tooth 1312 is moving laterally, the driving tooth 1312 can drive the transmission plate 1404 to move synchronously through the slider 1403 during the movement. During the movement, the transmission plate 1404 can drive the transmission column 1407 to rotate through the squeezing force of the driving shaft 1406 on the spiral track groove 1408. During the rotation, the transmission column 1407 can drive the transmission wheel 1412 to rotate synchronously. Through the pulley transmission composed of the transmission wheel 1412, the driven wheel 1409 and the transmission belt 1410, the driven wheel 1409 can drive the worm 1411 to rotate. When the worm 1411 rotates, the worm 1411 and the turbine 1414 cooperate to allow the turbine 1414 to drive the reciprocating screw 1413 to rotate, thereby realizing the movement of the seat 141 The movable seat 1415 moves back and forth vertically along the reciprocating screw 1413. When the movable seat 1415 moves downward, the movable seat 1415 can drive the two slide plates 1417 to move toward each other through the push-pull plate 1419 during the downward movement, so that the connecting block 1418 can drive the impact rubber head 1422 to vibrate the casting core body on the detection position through the transmission rod 1420, so that the impurity particles attached to the casting core body fall off under the impact of the vibration force, and are conveniently removed under the action of the airflow of the blowing pipe 1306. When the movable seat 1415 moves upward, the two slide plates 1417 can be driven by the push-pull plate 1419 to move away from each other, which is conducive to the reset of the impact rubber head 1422, and the impact rubber head 1422 can be intermittently vibrated along with the vertical reciprocating movement of the movable seat 1415.
