Be illustrated for the testing process of part to be detected to the pick-up unit in the utility model in Fig. 1 below:
First the first register pin 14 of two on drift 10 is inserted in two holes 2 ' (detect aperture) of installing plate 1 ' (part to be detected), first register pin 14 is fitted with hole 2 ', if the summit of installing plate 1 ' 3 ' (reference point) can enter the detection faces of the first detection lug 15, then the hole 2 ' on explanation installing plate 1 ' and the size between summit 3 ' are within full-size.
Then second register pin 24 of two on no-go gage 20 is inserted in two holes 2 ' of installing plate 1 ', second register pin 24 is fitted with hole 2 ', if the summit 3 ' of installing plate 1 ' can not enter the detection faces of the second detection lug 25, then the hole 2 ' on explanation installing plate 1 ' and the size between summit 3 ' are outside minimum dimension.
After being detected by use drift 10 and no-go gage 20, if the hole 2 ' on installing plate 1 ' and the size between summit 3 ' are within full-size, and hole 2 ' on installing plate 1 ' and the size between summit 3 ' are outside minimum dimension, then illustrate that the upper size between hole 2 ' and summit 3 ' of installing plate 1 ' is in Measurement Allowance, qualified, if the summit 3 ' of installing plate 1 ' can enter the detection faces of the second detection lug 25, or the summit 3 ' of installing plate 1 ' can not enter the detection faces of the first detection lug 15, then illustrate that installing plate 1 ' is underproof.
Due in above-mentioned testing process, without the need to measuring the concrete dimensional values of each several part of part to be detected, just can judge that whether qualified part is, therefore detection efficiency is very high.
For three-coordinates measuring machine is measured, avoid the expensive cost and time waste that use three-coordinates measuring machine measurement to bring, three-coordinates measuring machine price more than 20 ten thousand yuan, measures a part time at about 5 minutes.The measurement mechanism price that this clearly demarcated patent adopts is that the time of measuring one only has 0.2 minute, and its cost and Measuring Time reduce greatly less than 1000 yuan.
Certainly, be more than preferred implementation of the present utility model.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model ultimate principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
