example 2
As shown in fig. 1, 2, 6, and 8, an illuminating member 9 is provided on the rotary member 5 at a position corresponding to the scanner 2;
the central processing unit is internally provided with a sampling unit, a burr identifying unit, a counting unit, a comparing unit, a recording unit, a scanning unit, a graph identifying unit, a difference value calculating unit and a burr quantity calculating unit;
the central processing unit 6 is also internally provided with a burr identification unit, a counting unit, a comparison unit, a recording unit, a scanning unit, a graph identification unit, a difference value calculation unit and a burr quantity calculation unit, wherein the sampling unit performs multi-point sampling on the shot spiral line, the counting unit counts the burr quantity of each area, the burr quantity calculation unit calculates the average burr quantity Z in each area, and the comparison unit compares the calculated average burr quantity Z with a set threshold value;

for example, in order to improve the drilling efficiency, the rotation rate of the drill bit or the feed rate of the drill bit is generally adjusted to be faster, when the feed rate of the drill bit is faster, the grinding time of the drill bit on the inner wall of the hole is shortened, so that the grinding condition of the inner wall of the hole is poorer, the grinding condition of the inner wall of the hole is generally ignored in the measurement process to be measured, so that the drilling accuracy is reduced, the inner wall of the hole can be shot and observed in the mode, the grinding condition in the hole can be better observed, and the drilling accuracy is further improved;
the hole grinding condition was determined as follows: carrying out multipoint sampling on a shot spiral line through sampling, wherein the areas of sampling areas are the same, the number of the sampling areas is recorded as N, the number of burrs in each area is counted through a counting unit, the number of the burrs in each area is respectively represented by B1, B2, B3, … … and BN, the average burr number Z in each area is calculated through a burr number calculating unit, Z = (B1 + B2+ B3+ … … + BN)/N, the calculated average burr number Z is compared with a set threshold value through a comparison unit, if the average burr number Z is larger than the threshold value, the polishing condition of the inner wall of the hole is poor, the polishing accuracy is low, and if the average burr number Z is smaller than the threshold value, the polishing condition of the inner wall of the hole is good, and the polishing accuracy is high;
secondly, for example, during drilling, if the integrity of the material is good, during the drilling process, when the acting force between the drill bit and the workpiece is large, the material connectivity is good due to the good overall performance of the material, and the inner wall of the hole may form a concave part after drilling, as shown in a part a in fig. 8, the measurement of the condition of the inner wall of the hole is generally ignored during the measurement process, so that the accuracy of drilling is reduced, the inner wall of the hole can be shot and observed by the method, so that the radian condition in the hole can be better observed, when the scanned spiral line has a radian change, as shown in fig. 8, the condition that the inner wall of the hole is missing can be determined, so that the radian condition of the inner wall of the hole can be observed by scanning, and the accuracy of drilling is further improved;
the radian condition of the inner wall of the hole is determined in the following way: pre-scanning a hole with a processing standard to obtain a standard spiral line, performing forward projection on the spiral line, inputting the spiral line into a recording unit, performing multiple forward projections on the recorded spiral line through a projection unit, comparing the forward projected spiral line with the scanned standard forward spiral line every time, if the spiral line after the multiple forward projections and the standard forward projected spiral line are all in an error allowable range, indicating that the radian of the inner wall of the hole meets the standard, and the accuracy is higher, if the spiral line after the one forward projection and the standard forward projected spiral line are not in the error allowable range, indicating that the radian of the inner wall of the hole does not meet the standard, and the accuracy is lower;
the way that the helix of each forward projection is compared with the standard forward helix of the scan is as follows: scanning a scanned standard forward spiral line outline through a scanning unit, recording the scanned outline into a recording unit, scanning the forward projected spiral line outline at each time through the scanning unit, performing superposition comparison on the forward projected spiral line outline at each time and the standard forward spiral line outline through a comparison unit, identifying the maximum position of the changed part of the forward projected spiral line outline at each time through a pattern identification unit when the forward projected spiral line outline is changed, calculating the difference value of the maximum position of the changed part of the forward projected spiral line outline at each time from the forward spiral line outline at the corresponding position standard through a difference value calculation unit, comparing the calculated difference value with a standard threshold value, if the obtained difference value is greater than the threshold value, indicating that the radian condition of the inner wall of the hole is changed, indicating that the radian condition of the inner wall of the hole is low, and if the obtained difference value is less than or equal to the threshold value, indicating that the radian condition of the inner wall of the hole is not changed, indicating that the radian condition of the inner wall of the hole is high;
it should be noted that adjacent turns of the spiral path formed by scanning by the scanner 2 are mutually attached to ensure that the large-area inner wall of the hole is scanned;
example 3
Inputting a detected standard value into the central processing unit 6 in advance, after measuring the actual height and the inner diameter of the hole, the central processing unit 6 compares the measured actual height and the inner diameter of the hole with the input standard value, if the measured actual height of the hole is smaller than the input standard value, the central processing unit 6 outputs a character that the height of the detection hole is smaller than the standard value through the display 7, if the measured actual height of the hole is larger than the input standard value, the central processing unit 6 outputs a character that the height of the detection hole is larger than the standard value through the display 7, if the measured actual inner diameter of the hole is smaller than the input standard value, the central processing unit 6 outputs a character that the inner diameter of the detection hole is smaller than the standard value through the display 7, if the measured actual inner diameter of the hole is larger than the input standard value, the central processor 6 outputs a character that the inner diameter of the detection hole is larger than the standard value through the display 7, the hole with the hole height smaller than the standard value and the hole with the hole height larger than the standard value can be distinguished through the mode, the hole with the hole height larger than the standard value is scrapped, the hole with the hole height smaller than the standard value can be continuously reprocessed, and therefore a large amount of waste of raw materials caused by scrapping of raw materials is avoided.
