When measuring, the standard flow gauge is first placed on the measuring mechanism 3 through the gauge calibration mechanism 2 for size calibration; then the workpiece is transported to the feeding mechanism 7 through the feeding mechanism 1, and then the workpiece is transported to the measuring mechanism 3 by the feeding mechanism. Outer diameter, roundness, taper, straightness and other parameters are inspected, and unqualified workpieces are removed; finally, qualified workpieces are unloaded from the inspection line and transferred to the next process through the handling mechanism. The specific working principle is as follows:

After the two first manipulators 2-6 grab the standard gauge (not shown in the figure) placed on the positioning plate 2-5 from the initial position under the drive of the first snatch cylinder 2-7, in the secondary vertical direction The cylinder 2-11, the secondary vertical slide 2-10, the primary vertical cylinder 2-9, and the primary vertical slide 2-8 rise to a predetermined height, and the second motor 2-1 passes through the horizontal screw 2-13 drives the secondary vertical cylinder 2-11 to move to the right on the third horizontal guide rail 2-12 to the top of the positioning probe 3-10, and then the secondary vertical cylinder 2-11 and the secondary vertical slide plate 2 -10. The effect of the first-level vertical cylinder 2-9 and the first-level vertical slide plate 2-8 drops down to the predetermined position, and the two first manipulators 2-6 loosen the standard gauge under the drive of the first snatch cylinder 2-7 Then return to the predetermined height; after the standard gauge falls into the positioning groove of the positioning probe 3-10, the pneumatic ejector rod 9 pushes the standard gauge forward to the position of the baffle (not shown in the figure) and then returns to complete the standard quantity regulation bit. The first motor 3-12 moves to the left under the push of the second horizontal cylinder 3-2 to the top of the positioning probe 3-10, and the second lifting cylinder 3-5 drives the first motor 3-12 to descend and pass the pressure. The rod shaft 3-11 drives the standard gauge to rotate, the positioning probe 3-10 automatically measures and records the data of the standard gauge, then the first motor 3-12 returns to the initial position, and the first manipulator 2-6 descends and grabs the standard gauge. Put it back to its original position to complete the dimensional calibration work.

When loading materials, arrange the workpieces (valve stems) on the support plate 1-9 one by one; The material blocking ram 1-2 on the side descends to isolate the first workpiece and the second workpiece; when the material blocking ram 1-2 on the right is lifted up and the first workpiece passes through the material blocking ram Lower again, at the same time, the left dam 1-2 is lifted upwards, and the second workpiece passes through the ram and then falls again; in such a reciprocating cycle, the workpieces will continuously pass through the two rams 1-2 and drop on the feeding mechanism 7, the feeding work is completed.

When the workpiece falls from the feeding mechanism 1 into the V-shaped groove 7-4 of the second feeding plate 7-2, the first horizontal cylinder 7-9 passes through the first horizontal slider 7-10 and the support (not shown in the figure) out) drives the second feeding plate 7-2 and the first feeding plate 7-1 to move rightward on the first horizontal guide rail 7-13; when reaching the predetermined position, the first lifting cylinder 7-6 retracts and drives the second The feed plate 7-2 and the first feed plate 7-1 descend, and the workpieces will fall into the V-shaped groove 7-4 of the first positioning plate 4 and the second positioning plate 7-3 for temporary storage; the second feed plate 7-2 and the first feed plate 7-1 return to the initial position under the action of the first horizontal cylinder 7-9, and the first lift cylinder 7-6 drives the second feed plate and the first feed plate 7-1 to rise simultaneously, ready to To undertake the next workpiece, the workpiece is continuously sent to the right end from the left end of the feeding mechanism 7 . During the transportation process, the left baffle plate 7-14, the middle baffle plate 7-8, and the right baffle plate 7-7 can prevent the workpiece from falling due to vibration.

When the workpiece moves to the two positioning probes 3-10, the workpiece will fall into the positioning groove of the positioning probe 3-10. At this time, the pneumatic ejector rod 9 will push the workpiece forward to the baffle and return shrink to realize workpiece detection and positioning. Then the first motor 3-12 drives the standard gauge to rotate through the pressure rod shaft 3-11, and the positioning probe 3-10 automatically measures and records the data of the standard gauge, and then transmits the data to the measurement control system in real time through the sensor to calculate the valve stem outer diameter. Diameter, roundness, taper, straightness, and make intelligent judgments. After the measurement work is completed, the first motor 3-12 returns to the initial position, waiting for the next workpiece to be measured.

When a workpiece is measured, the second feeding plate 7-2 and the first feeding plate 7-1 will take the workpiece out from the positioning probe 3-10 and transfer it to the first positioning plate 4 and the second positioning plate 7 -3 in the V-shaped groove 7-4. When the workpiece passes the position of the screening mechanism, the two blowing nozzles 6 will blow the unqualified workpiece into the corresponding material box 10 through the guide tube 8, and at the same time, the alarm device (not shown in the figure) will issue an alarm and qualified workpieces will continue to transfer to the first positioning plate 4 and the second positioning plate one by one through the V-shaped groove 7-4 to the right under the action of the second feeding plate 7-2 and the first feeding plate 7-1 7-3 to the far right, thus completing the automatic screening work.

When the qualified workpiece arrives in the V-shaped groove 7-4 at the rightmost end of the first positioning plate 4 and the second positioning plate 7-3, the second snatch cylinder 5-5 will grab the workpiece by the second manipulator 5-4, and The third lifting cylinder 5-1 and the second connecting plate 5-8 drive the workpiece to rise; after the workpiece rises to a certain height, the third horizontal cylinder 5-2 will drive the third lifting cylinder 5-1 along the guide column 5 -6 moves to the right to the predetermined position; the second manipulator 5-4 releases the workpiece and returns to the initial position, and grabs the next workpiece, so that the qualified workpiece can be transported to other automation equipment in a reciprocating cycle.

When it is necessary to measure workpieces of different lengths, just turn the handwheel 11 to drive the vertical slide plate 7-12 to move back and forth along the longitudinal guide rail 7-11 through the screw 13, thereby adjusting the first positioning plate 4 and the second positioning plate 7-11. 3 distances between.
