Between the first datum mark D1 and the second datum mark D2 stated；Center in second row riveting point respectively with each riveting of first row
The center of contact is corresponding.The center of the first row riveting point is L1 away from the distance at the edge of the Y-direction of workpiece, described
The distance at the edge of -Y direction of the center of second row riveting point away from workpiece is also L1.Center between adjacent riveting point is away from basis
Design requirement determines.
Step 2: installation peripheral frame positioning mechanism.
Step 3: positioning and clamping workpiece.
Step 4: the initial position of riveting point on amendment workpiece.
The detailed process of riveting point initial position is on the amendment workpiece:
Step 1: the Cutter coordinate system O'-X'Y'Z' of boring and riveting machine is adjusted.Make the Cutter coordinate system O'-X'Y' of the boring and riveting machine
The origin of Z' is overlapped with the origin for determining initial O-XYZ coordinate system on workpiece and change in coordinate axis direction is identical.
Step 2: coordinate letter of the riveting point initial position in the Cutter coordinate system O'-X'Y'Z' of the boring and riveting machine is extracted
Breath.
Extracted by CATIA software and record the datum mark initial coordinate information and each riveting point initial position
Coordinate information.
The initial coordinate information of extracted datum mark isIt include the first datum mark D1 and the second base
The initial coordinate information of D2 on schedule；D therein is workpiece datum mark, and n indicates n-th of datum mark, n=1,2 ..., l.

The modification method of the datum mark D2 coordinate is identical as the method for said reference point D1 coordinate modification.
In the amendment to each datum mark coordinate, if the grid deviation of the first datum mark D1 and the second datum mark D2 are equal
MeetIt then can directly be riveted, go to step 5；Otherwise, riveting point coordinate is repaired
Just.
The amendment of III riveting point grid deviation
According to design requirement, the distance between datum mark and adjacent riveting point are equal to rivet pitch.It is inclined because of riveting point Z-direction
Difference can adaptively be adjusted by boring and riveting machine, therefore, the deviation of Z-direction without amendment, only need to X to and the deviation of Y-direction repair
Just.
A, the determination of riveting point grid deviation.
It is i to the riveting point r number consecutively between the first datum mark D1 and the second datum mark D2, is denoted as ri, i=
1......k/2, k therein is the number of riveting point.
Each riveting point between the first datum mark D1 and the second datum mark D2 is successively labeled as r1、r2…rk/2, and advise
The fixed riveting point r adjacent with the first datum mark D11For the first riveting point.
Calculate the deviation of the first datum mark D1With the deviation of the second datum mark D2
Between difference, obtain the deviation increment △ between two datum marks.
The deviation increment △ is divided into 1+k/2 parts, obtains the average increment of each riveting point.By obtained each riveting
The average increment of point increases respectively to each riveting point r1、r2…rk/2Coordinate value on to get arrive each riveting point r1、r2…rk/2It repairs
Coordinate value after just.
In conjunction with the grid deviation value of the first datum mark D1 and the second datum mark D2, the first datum mark D1 and the second datum mark D2
Between riveting point i X to grid deviation value beCoordinate of the riveting point i in Y-direction
Deviation is
B, the amendment of riveting point grid deviation.
By riveting point riX to grid deviation valueWith Y-direction grid deviation valueIt is included in riveting point r respectivelyiInitial coordinateIn, then revised seat
Mark
The process for repeating the amendment riveting point initial coordinate, is successively modified the initial coordinate of each riveting point, directly
To the amendment for completing all riveting point initial coordinates, the position coordinates of all riveting points are obtained.
Step 5: workpiece automatic Drilling/Riveting.Implement automatic Drilling/Riveting according to the position coordinates of revised riveting point.
Step 6: after riveting, boring and riveting machine is returned to original state, workpiece undercarriage, completes the brill riveting to workpiece.
