As shown in fig. 1 and fig. 2, a symmetry detecting apparatus 100 according to an embodiment of the present invention includes a first positioning mechanism 10, a second positioning mechanism 20, and a detecting block 8 disposed between the first positioning mechanism 10 and the second positioning mechanism 20.
In this embodiment, the product 9 to be inspected has a first hole 91 at one end and a second hole 92 at the other end. First positioning mechanism 10 includes first locating piece 1 and first locating pin 2, and first locating piece 1 is equipped with the first locating hole 11 with first locating pin 2 adaptation, and first locating hole 11 corresponds with the first hole 91 that is detected product 9 one end. The second positioning mechanism 20 includes a second positioning block 3 and a second positioning pin 4, the second positioning block 3 is provided with a second positioning hole 31 adapted to the second positioning pin 4, and the second positioning hole 31 corresponds to the second hole 92 at the other end of the detected product 9.
The detection block 8 is provided with a notch 81 corresponding to the middle structure 93 of the product 9, and the notch 81 is symmetrical about the central axis 12 between the first positioning hole 11 and the second positioning hole 31. One or more detection blocks 8 may be provided as required, and one or an even number of card slots 81 may be provided correspondingly. When there are a plurality of slots 81, the slots 81 on both sides of the central axis 12 are also symmetrical with respect to the central axis 12. The shape of the slot 81 corresponds completely to the middle structure 93 of the product 9 to ensure the accuracy of symmetry detection. The central structure 93 of the product 9 extends in a straight line and, correspondingly, the pockets 81 also extend in a straight line.
Based on the structure of the product 9 to be inspected, the center of the first positioning hole 11 and the center of the second positioning hole 31 are located on the same straight line to conform to the straightness of the product 9. And, the top surface of first locating piece 1 and the top surface of second locating piece 3 are located the coplanar to be in the same horizontal plane when guaranteeing product 9 to detect.
When the first positioning pin 2 passes through the first hole 91 and extends into the first positioning hole 11, and the second positioning pin 4 passes through the second hole 92 and extends into the second positioning hole 31, if the middle structure 93 of the detected product 9 can be completely attached to the clamping groove 81, the symmetry of the product 9 is qualified.
