Fig. 3 is the flow chart of the processing method, as shown in figure 3, the processing method includes:
Step 101:Workpiece to be processed is fixed on the processing datum of lathe.
In above-mentioned implementation, lathe can be common boring machine, i.e., an endoporus can only be processed simultaneously Boring machine, processing datum refer to placing the top surface of the workbench of workpiece to be processed, and workbench can be with horizontally disposed.
Step 102:Pass through the endoporus of tool sharpening first of lathe.
Step 103:The center height of the first endoporus is measured, lathe is arrived at the center of a height of first endoporus in center of the first endoporus The distance between processing datum.
Step 104:Cutter is moved in edge towards the direction of the second endoporus, and passes through the endoporus of tool sharpening second.
Step 105:The center height of the second endoporus is measured, lathe is arrived at the center of a height of second endoporus in center of the second endoporus The distance between processing datum.
Step 106:The high difference between the center height of the second endoporus in center of the first endoporus is calculated, difference is first poor Value.

When the processing method provided by the embodiment of the present invention processes endoporus, after the second endoporus is processed, calculate Difference between first endoporus and the center height of the second endoporus, because the first endoporus and the second endoporus are parallel to each other arranged for interval, And when processing the first endoporus, cutter is not by translation, so lathe can ensure that the center height of the first endoporus is to meet to add Work required standard center is high, therefore, calculates the difference between the first endoporus and the center height of the second endoporus, equivalent to calculating The high difference between center for standard height in the center of second endoporus, then according to the difference along the processing base perpendicular to lathe After the direction adjustment cutter in quasi- face, then the second endoporus is processed, i.e., can ensure that the center of the second endoporus after processing is high Also processing request can be met.
Fig. 4 is the flow chart of the processing method of another endoporus, and the applicable workpiece of the processing method is same as above, herein Do not repeat.
Referring to Fig. 4, the processing method includes:
Step 201:Clean lathe and workpiece to be processed.
This way it is possible to avoid the impurity on lathe and workpiece to be processed impacts to processing.
Step 202:The first workpiece to be processed and the second workpiece to be processed, and first are fixed on the processing datum of lathe Workpiece to be processed and the second workpiece to be processed are parallel to each other arranged for interval.
In above-mentioned implementation, lathe can be common boring machine, i.e., an endoporus can only be processed simultaneously Boring machine, processing datum refer to placing the top surface of the workbench of workpiece to be processed, and workbench can be with horizontally disposed.
Step 203:Whether the gap between detection workpiece to be processed and the processing datum of lathe is more than clearance requirement value, If the gap between the first workpiece to be processed and the second workpiece to be processed and the processing datum of lathe is more than clearance requirement value, Step 202 is then re-executed, if being not more than clearance requirement value, performs step 204.
Specifically, the gap between the first workpiece to be processed and the second workpiece to be processed and the processing datum of lathe can be with Measured by clearance gauge.
Preferably, clearance requirement value can be 0.03mm.During concrete operations, the clearance gauge that thickness is 0.03mm can be inserted Gap, if can not insert, then it represents that the gap is less than 0.03mm.
It should be noted that after step 202 is re-executed, if between workpiece to be processed and the processing datum of lathe Gap be still more than clearance requirement value, it is likely that be that step 201 is not carried out in place, then re-executing step 201.
Step 204:Pass through the first endoporus of the workpiece to be processed of tool sharpening first of lathe.
In step 204, the cutter of lathe can be boring cutter, can be in three times in first when processing the first endoporus Hole is processed, and during processing three times, the internal diameter of the first endoporus progressively reaches design size, so as to ensure that in first The machining accuracy in hole.
Step 205:The center height of the first endoporus is measured, lathe is arrived at the center of a height of first endoporus in center of the first endoporus The distance between processing datum.
Specifically, step 205 can be realized by following steps:
First, the radius of the first endoporus and the inwall of the first endoporus are measured to the most narrow spacing between the processing datum of lathe From.Specifically, the radius of the first endoporus can be measured by inside micrometer, the inwall that the first endoporus is measured by height gauge arrives Minimum range between the processing datum of lathe.
Then, calculate the inwall of the first endoporus to the minimum range between the processing datum of lathe and the first endoporus partly Between footpath and value, to obtain the center of the first endoporus height.
Step 206:Cutter is moved in edge towards the direction of the second endoporus, and passes through the endoporus of tool sharpening second.
In step 206, in mobile cutter, ensure that cutter moves parallel to processing datum as far as possible, to avoid influenceing The center of second endoporus is high.
It should be noted that when processing the second endoporus, the center height due to that can not ensure the second endoporus can be standard Center is high, the possibility that subsequent step needs to be adjusted the center height of the second endoporus be present, so during the second endoporus of reprocessing, Reserved certain adjustment surplus is needed, that is, the internal diameter of the second endoporus processed should be less than design size.
Step 207:The center height of the second endoporus is measured, lathe is arrived at the center of a height of second endoporus in center of the second endoporus The distance between processing datum.
In step 207, the high measuring method in the center of the second endoporus and the center of the first endoporus in step 205 are high Measuring method is identical, will not be described here.
Step 208:The high difference between the center height of the second endoporus in center of the first endoporus is calculated, difference is first poor Value.
In a step 208, because the first endoporus and the second endoporus are parallel to each other arranged for interval, and the first endoporus is being processed When, cutter is not by translation, so lathe can ensure that the center height of the first endoporus is the center for standard for meeting processing request Height, therefore, the difference between the first endoporus and the center height of the second endoporus is calculated, equivalent to the center for having calculated the second endoporus Difference between high and center for standard height, i.e. difference of the first difference between the center height and center for standard height of now the second endoporus Value.
Step 209:Cutter is adjusted along the direction of the processing datum perpendicular to lathe, the adjustment distance of cutter is poor for first Value, and process the second endoporus again by cutter.
So, the center height of the second endoporus can be caused to be more nearly center for standard height.
It should be noted that the quality for being limited to boring machine is different, during cutter moves horizontally, cutter be possible to The upper deviation or downward deviation, therefore, cutter is adjusted along the direction of the processing datum perpendicular to lathe, can be according to reality Situation adjusts upward cutter or adjusts cutter downwards, and specific adjustment direction can judge according to the positive and negative of the first difference, example Such as, if the center height of the first endoporus center that subtracts the second endoporus is high, the first obtained difference be on the occasion of, then it represents that in second The center height in hole is high in center for standard, now needs to adjust upward cutter.
Step 210:Difference between the center height of the second endoporus after calculating the center height of the first endoporus and processing, difference For the second difference;Judge whether the second difference meets center high request value range, if the second difference is unsatisfactory for center high request Value range, then step 209 is performed again by adjustment distance of the second difference, if the second difference meets center high request scope Value, then perform step 211.
Specifically, high request value range in center can be -0.02~0.02.
Step 211:After detecting centre-to-centre spacing between the first endoporus and the second endoporus and the first endoporus and processing second in Whether the difference between centre-to-centre spacing between hole meets centre-to-centre spacing claimed range value, if between the first endoporus and the second endoporus The difference between the centre-to-centre spacing between the second endoporus after centre-to-centre spacing and the first endoporus and processing is unsatisfactory for centre-to-centre spacing claimed range Value, then cutter is adjusted along the processing datum direction parallel to lathe, and the second endoporus is processed again.
It should be noted that by multiple practical operation, cutter is found in the displacement on processing datum direction, Substantially cutter will not be caused to produce the skew on parallel to processing datum direction, therefore, in order to simplify manufacturing procedure, step 211 can omit.
17SG1F1420
Specifically, step 211 can be realized by following steps:
First, the centre-to-centre spacing between the first endoporus and the second endoporus, the center between the first endoporus and the second endoporus are obtained Away from the distance for being moved to the second workpiece to be processed by the first workpiece to be processed before the second endoporus is processed for cutter.
It should be noted that because boring machine can ensure the degree of accuracy that cutter moves horizontally, so cutter is in processing second The distance of the second workpiece to be processed is moved to before endoporus by the first workpiece to be processed, the first endoporus and the second endoporus can be considered as Between reference center distance.
Then, the centre-to-centre spacing between the second endoporus after the first endoporus and processing is calculated, the after the first endoporus and processing Centre-to-centre spacing between two endoporus is calculated by equation below:
Wherein, a1For the abscissa at the first endoporus center, a2For the abscissa at the second endoporus center after processing, b1For The ordinate at one endoporus center, b2For the ordinate at the second endoporus center after processing, centered on l away from.
Specifically, centre-to-centre spacing claimed range value can be -0.06~0.06.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
