With the help of the effect of gravity, the spring that can wear out from outer diameter expert's rule 22 is qualified for the article, and unqualified spring can block in outer diameter expert's rule 22, and first cylinder 23 action this moment pushes out outer diameter expert's rule 22 to the side, opens two half rules 211 again in order to reject the nonconforming article.
The spring qualified through the outer diameter straightness detection slides into the positioning ring 324 on the positioning tool 32 from the inclined rail 21, and the second air cylinder 34 acts to enable the inner diameter gauge 33 to extend out of the inner diameter gauge through hole. If the inner diameter gauge 33 can smoothly pass through the spring, the spring is qualified; if the contact sensor 35 senses that the spring is jacked up by the inner diameter gauge, the spring is an unqualified product, and the unqualified product is removed by a removing mechanism additionally arranged.
After the inner diameter straightness is detected to be qualified, the second rotary air cylinder 323 acts to align the inclined positioning tool 32, and then the first rotary air cylinder 312 rotates to transfer the spring to the front of the height detection mechanism 4. The second machine then transfers the spring to the spring staking head 44 for height sensing.
When the height detection is started, the third air cylinder 45 is pressed downwards to enable the sensing block 46 to move towards the spring, the third air cylinder 45 moves upwards after the sensing block 46 contacts the spring, meanwhile, the displacement sensor 47 detects the displacement distance of the sensing block 46, and the height of the spring can be calculated by subtracting the displacement distance from the original height of the sensing block 46 in the background.
After the height is detected, perpendicularity detection is carried out, the camera 51 images the spring and the back plate 52, and the computer can calculate the perpendicularity by measuring the included angle between the edge of the spring and the vertical reference line 521.
