Pre-treating: regular metal samples and irregular metal samples need to be classified, and the first type detects the regular metal samples.

The working principle is as follows: set up a set of notch 4 of placing through the upper surface at analysis appearance body 1, and place first step motor 2 of notch 4 interior installation, meanwhile at analysis appearance body 1's upper surface reinstallation second step motor 5, wherein place notch 4 and second step motor 5 and present the cross form, control first step motor 2 and second step motor 5, first step motor 2's effect lies in driving second step motor 5 displacement from front to back, and second step motor 5's effect lies in driving supporting shoe 7 displacement from front to back, supporting bar 15 is gone up in the support post 8 cooperation of being connected by the left side of supporting shoe 7, can realize supporting bar 15 about and displacement from top to bottom.

By placing the metal sample above the right bracket 31 and the left bracket 38, the sample with a width larger than the distance between the left bracket 38 and the right bracket 31 is certainly aimed at, and a group of mesh plates which are not metal are arranged between the right bracket 31 and the left bracket 38 and are used for supporting the metal sample. When the support bar 15 moves backwards, the displacement rod 37 can be pulled to displace back and forth on the outer walls of the two groups of fixed pillars 35, and then when the support bar 15 displaces left and right, the cross bolt 36 can be controlled to displace left and right in the notch above the outer wall of the displacement rod 37, so that the rectangular analysis of the spark light source excitation hole 10 on the surface of the metal sample is realized.

The above description is only for samples in which the analysis area is a regular rectangle. If the metal sample of the irregular region of analysis, through dismantling detachable opening plate 39, and rotate through controlling the motor drive dish 33 drive shaft, protruding pillar 29 also can rotate when motor drive dish 33 rotates, and contact the teeth of a cogwheel on the external wall of external screw thread pillar 16, make rolling disc 30 carry out intermittent type formula and rotate, final purpose causes external screw thread pillar 16 to carry out intermittent type formula and rotates, because external screw thread pillar 16 and built-in screw hole 17 are the thread groove connection, external screw thread pillar 16 upwards displaces when external screw thread pillar 16 rotates clockwise, external screw thread pillar 16 downwards displaces when external screw thread pillar 16 anticlockwise rotates.

Considering that the external threaded strut 16 displaces downwards, the rotating rod 21 is pushed to displace downwards, when the rotating rod 21 displaces downwards, the metal sample 19 is pushed to rotationally displace downwards, if the metal sample 19 is irregular, when the metal sample 19 rotates, the irregular part of the metal is in a convex state, or the irregular part of the metal sample is in a concave state, the metal sample is contacted with the magnetic block 14 to be attracted, no matter which one, the magnetic block 14 is used for performing arc rotation on the rotated metal sample, so that when the spark light source excitation hole 10 detects the metal sample 19, firstly, the metal sample 19 is detected from the periphery of the metal sample 19, and the inclined magnetic strip 18 displaces downwards through the rotation of the external threaded strut 16, the inclined magnetic strip 18 is inclined, the metal sample 19 is slowly repelled outwards, and when the uppermost end of the inclined magnetic strip 18 is contacted with the metal sample 19, the metal sample 19 is attracted to move towards the direction of the inclined magnetic strip 18, the spark light source excitation hole 10 is scanned on the rightmost side of the bottom of the metal sample 19 and rotates, after the metal sample 19 slowly moves downwards, the metal sample 19 is repelled outwards, when the metal sample is repelled, the support pillar 22 is used for moving in the direction from inside to outside of the strip-shaped groove block 23, the spark light source excitation hole 10 is enabled to scan the inner side of the periphery of the metal sample 19, one circle of scanning is achieved from the outer ring to the inner ring, and finally the whole analysis is conducted on the surface of the irregular metal sample. In the analysis process, external screw strut 16 upwards displaces when rotating, will drive external connecting rod 40 upwards displacement, but external connecting rod 40 can not rotate, montant 41 that is connected through external connecting rod 40's top is for going into the arc wall 43 for the card in, when external screw strut 16 is carrying out the pivoted time, montant 41 can not rotate, can realize carrying out upwards displacement to external connecting rod 40 that montant 41 outer wall side is connected, the platform 11 upwards displacement is controlled in the pulling simultaneously, make the spark light source who controls on the platform 11 arouse the hole 10 and be covered by the metal specimen when the metal specimen removes all the time.

The sample to be detected that this application is directed against is iron-based metal material, and when carrying out the detection of irregular sample, irregular sample adsorbs on adsorbing magnetic path 25. And the magnetic block 14 and the inclined magnetic strip 18 are arranged for irregular sample detection, and the magnetic block 14 and the inclined magnetic strip 18 need to be detached for avoiding magnetic interference of the regular sample during regular sample detection.

When the magnetic block 14 attracts the metal sample 19, the metal sample 19 displaces towards the magnetic block 14, and the inserting support column 20 is caused to displace towards the right of the through hole below the outer wall of the rotating rod 21, so that the attraction effect is realized, and the irregular metal protruding part or the irregular metal recessed part is scanned.
