The eddy current induction probe 13 is provided inside the detection housing 1, and a switching mechanism 12 is provided on the outer side of the transverse support 6. The switching mechanism 12 drives the transverse support 6 and the eddy current induction probe 13 to rotate and tilt, thereby dynamically adjusting and controlling the housing of the eddy current induction probe 13 at different angles or orientations.

[0023] In this embodiment, the adjustment mechanism 11 includes positioning holes 7, sleeve bases 8, industrial cameras 9, display screens 10, and sliding grooves 14. Positioning holes 7 are evenly spaced on the outer side of the transverse support 6, and sleeve bases 8 are evenly spaced on the outer side of the transverse support 6. The bottom end of one set of sleeve bases 8 is connected to the industrial camera 9, and the bottom end of another set of sleeve bases 8 is connected to an eddy current induction probe 13. The display screen 10 is arranged directly above the sleeve bases 8, and the display screen 10 is connected to the industrial camera 9 by wires.

[0024] In this embodiment, the transverse support 6 is connected to the outer side of the sleeve base 8 through the sliding groove 14 opened at the bottom. The sliding groove 14 guides the sleeve base 8, and multiple sets of sleeve bases 8 are used to position and tilt the components.

[0025] In this embodiment, the switching mechanism 12 includes an eccentric wheel 4, a bearing disc 5, a transverse support 6, a motor 15, and a fan 16. The outer side of the eccentric wheel 4 is connected to one side of the transverse support 6, and the other side of the transverse support 6 is connected to the outer side of the bearing disc 5. One side of the bearing disc 5 is connected to a detection housing 1, and the outer side of the detection housing 1 is connected to the motor 15. The inner end of the detection housing 1 is symmetrically provided with fans 16, and the circulating fans 16 perform dust removal treatment on the engine cylinder block.

[0026] In this embodiment, the motor 15 is connected to one side of the eccentric wheel 4 and the lateral support 6 through the output end, drives the lateral support 6 to tilt through the eccentric wheel 4, and acquires the direction of the detection equipment.

[0027] In this embodiment, the detection shell 1 is connected to the other side of the lateral support 6 through the bearing disc 5 arranged at the inner end, positions one side of the lateral support 6 through the bearing disc 5, and processes the lateral support 6 to tilt.

[0028] The engine cylinder body external defect detection equipment in actual application includes the following working contents:

[0029] Step 1: The operator first places the engine cylinder body outside the roller 2, then moves the engine cylinder body to the inside of the detection shell 1 through the roller 2, then according to the size of the cylinder body, pulls the sleeve block seat 8 to displace the sleeve block seat 8 outside the lateral support 6, adjusts the interval of the groups of sleeve block seats 8, inserts the bolt into the positioning hole 7, positions the sleeve block seat 8 outside the lateral support 6, and then completes the positioning processing of the groups of sleeve block seats 8;

[0030] Step 2: The fan 16 blows the inside of the engine cylinder, blows the inside debris or dust of the engine cylinder, scans the two-dimensional code information through the code scanning gun, moves the engine cylinder to the detection shell 1 through the roller 2, and then rotates the lateral support 6 to process the arc-shaped photographing of the cylinder body. The operator displays the collected image through the display screen 10, and displays the data in detail through the visual window 3 for recording.

[0031] Step 3: The operator installs the industrial camera 9 and the illuminating lamp outside the sleeve block seat 8, rotates the eccentric wheel 4 through the opening of the motor 15, rotates the lateral support 6 through the eccentric wheel 4, tilts the industrial camera 9 through the lateral support 6, takes 4 pictures through the industrial camera 9, ensures that all areas of the top surface of the part are detected through photographing, and compares the visual imaging. If the difference between the detection picture processing and the standard imaging exceeds the set standard, the equipment alarms.

[0032] Step 4: The eddy current induction probe 13 rotates into the cylinder hole of the cylinder body to start the eddy current detection one by one. When the high-frequency coil in the probe passes through the alternating current, a high-frequency oscillating magnetic field is generated. When the measured metal conductor approaches the probe, the surface of the conductor will generate a closed eddy current (eddy current) due to electromagnetic induction, and the direction is opposite to that of the coil magnetic field. When the eddy current detection signal exceeds the alarm range, the equipment alarms, and the computer displays the cylinder hole alarm size and related alarm information.

[0033] Thus, the disclosed embodiments are merely exemplary, and are not the only way to implement the present application. All changes within the scope of the present application or equivalent to the scope of the present application are included in the present application.
