When the object to be scanned can be placed smoothly, the object is placed on the holding table 24. At this time, when the connecting block 27 is rotated backward to the horizontal state, the two connecting rods 29 are rotated downward to the vertical state, the connecting rods 29 are located inside the storage groove, the connecting rods 29 are stored through the storage groove, and the clamping mechanism is in the stored state.
After the object is placed on the support table 24, the support table 24 is at the lowest position. The third servo motor 19 is started, the third servo motor 19 drives the worm 18 to rotate, the worm 18 is meshed with the worm wheel 20, the worm wheel 20 and the stud 21 are driven to rotate, the stud 21 is in threaded connection with the lifting seat, the lifting seat is driven to lift, the lifting seat is guaranteed to stably lift through the mutual clamping connection of the guide frame 23 and the guide groove, the lifting seat drives the bearing rod 22 and the bearing table 24 to synchronously lift, and objects on the bearing table 24 synchronously lift along with the bearing table 24. The object rises to correspond to the inner axis of the movable ring 6, so that the distance between the outer edge of the object and the inner cylindrical surface of the movable ring 6 is ensured to reach the optimal scanning distance.
And thirdly, when the scanned object moves upwards to a position convenient for scanning, the third servo motor 19 is turned off, the fourth servo motor 43 is started, the horizontal rotation of the bearing table 24 is controlled through the fourth servo motor 43, and then the horizontal rotation of the object is controlled, so that the subsequent scanning is facilitated. After the object rotates, the first servo motor 4 is started, the screw 3 is driven to rotate by the first servo motor 4, and the screw 3 is in threaded connection with the threaded block, so that the moving plate 5 is driven to move towards one side of the bearing table 24, the moving plate 5 drives the moving ring 6 to synchronously move, and the moving ring 6 drives the rotating mechanism and the scanning mechanism to synchronously move. When the moving ring 6 moves to the outer side of an object to be scanned, the second servo motor 16 is started, the second servo motor 16 drives the driven gear 14 to rotate through the driving gear 15, the driven gear 14 performs circle rotation motion on the outer side of the outer gear ring 8, and accordingly the scanning instrument 12 is driven to perform circle rotation motion around the outer gear ring 8, and therefore the object is scanned in all directions.
And fourthly, when the object to be scanned cannot be placed stably, the object needs to be clamped by the clamping mechanism and then scanned. The connection block 27 and the connection rod 29 are rotated forward from the receiving groove at the rear side until the connection seat and the connection rod 29 are in a horizontally forward state.
The two springs 31 are then compressed by pulling the anti-drop blocks on the two guide rods 30, the two holding webs 35 being moved away from each other, and the object to be scanned being placed between the two holding webs 35. The anti-slip blocks on the two guide rods 30 are then released and the two springs 31 begin to rebound, thereby allowing the two holding nets 35 to hold the object. The first servomotor 4 is activated so that the moving ring 6 moves to the outside of the object and the holding net 35. And then the second servo motor 16 is started, so that the scanning instrument 12 is controlled to perform circumferential rotary motion around the outer toothed ring 8, and the object is scanned in all directions.
In the scanning process, the piston rod of the electric push rod 40 is contracted, the control rack 37 moves towards one side of the clamping seat 32, the rack 37 is gradually meshed with the outer gear ring 36, the rack 37 drives the outer gear ring 36 to rotate, the outer gear ring 36 drives the clamping seat 32 to rotate, and the clamping seat 32 drives the clamping net 35 to rotate, so that the object to be scanned can be rotated in a vertical plane, and the object can be scanned in all directions.
After the scanning is completed, the object is taken out from the holding net 35, and the holding structure is rotated back again to the inside of the storage groove.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
