Description
Technical field
The present invention relates to a kind of parts like bent pipes localization method, particularly relate to a kind of bend pipe location simply, parts like bent pipes processing positioning method accurately.
Background technology
Accurately locate adding man-hour requirement to parts like bent pipes, especially to foundry goods class bent pipe parts, traditional localization method is clamping after line, due to the increase of crossed process, not only increase cost of labor, and production efficiency is low.The processing of existing foundry goods parts like bent pipes is generally outer shape location, because foundry goods appearance and size deviation is larger, therefore clamping error is large, therefore part creates a lot of defective products in actual production, as process rear flange there is in uneven thickness, part for assembling time, flange excircle misalignment, centre-to-centre spacing dimension overproof, processing rear flange hole deviation greatly, even directly cause part rejection.
Summary of the invention
The present invention mainly provides that a kind of parts like bent pipes localization method is simple, positioning precision and the high parts like bent pipes processing positioning method of efficiency, solving the parts like bent pipes existed in prior art, to carry out adding man-hour positioning precision low, easy generation defective products, causes the technical problem of part rejection rate increase etc.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: parts like bent pipes processing positioning method, comprises following sequential steps:
1) get bend pipe clamping on bend pipe positioning tool, and make the flange face A of bend pipe two-port and flange face B outwardly;
2) with flange face A for benchmark, with probe detect and correct flange face A center reference aa;
3) theoretical flange face B center reference ba is conversed with the flange face A center reference after correction;
4) with the theoretical flange face B center reference ba conversed as benchmark, detect flange face B center reference bb with probe, calculate the difference t=(bb-ba detecting flange face B center reference bb and theoretical flange face B center reference ba)/2, and the coordinate system that must make new advances;
5) go out the center reference ab of flange face A again with new coordinate system conversion, calculate the difference y detecting flange face A center reference aa and ab;
6) preset the overproof alarming value n of flange face A, carry out overproof warning as y >=n, check bend pipe and clamping, if bend pipe is abnormal, reports abnormal and remove, if clamping is abnormal, after adjustment clamping, restart from step 1);
7) as y < n, then converse theoretical flange face B center reference ba ' according to the center reference ab of the flange face A conversed in step 5), calculate the difference x detecting flange face B center reference bb and ba ';
8) preset flange face B ultrasonic difference alarming value m, carry out overproof warning as x >=m, check bend pipe and clamping, if bend pipe is abnormal, reports abnormal and remove, if clamping is abnormal, after adjustment clamping, restart from step 1);
9) as x < m, bend pipe location is qualified.
During location, first with A face for roughing standard, probe detects A face and also corrects, converse center, theoretical B face with the center, A face after correcting, forward B face to, then go to detect center, B face as benchmark with the B face theoretical center that A face converses, now can find to there is error, then error is converted.Such as, probe data display center, B face is lower than theoretical center value, the half of the deviate that just B center moved down, now namely can produce a new coordinate system, center, A face is gone out again with new coordinate system conversion, center, A face is surveyed at Bing Yongci center, overproof warning is set, then be converted to B face to go to detect center, B face, overproof warning is set, if whole process can be passed through smoothly, normal process can be carried out, otherwise clamping or part existing problems, the centre data of bend pipe two end flanges is detected by probe, then data compared and compensate, verify offset data again, last using compensation data carry out the processing of program, relative to the conventional mapping methods of parts like bent pipes, localization method is simply effective, positioning precision and efficiency high, improve the product qualified rate of part processing.
Therefore, parts like bent pipes processing positioning method of the present invention has following advantage: the centre data first being detected bend pipe two end flanges by probe, then data compared and compensate, verify offset data again, last using compensation data carry out the processing of program, and relative to the conventional mapping methods of parts like bent pipes, localization method is simple, positioning precision and efficiency high, improve part processing product qualified rate.
Accompanying drawing illustrates:
Fig. 1 is the clamping schematic diagram of parts like bent pipes of the present invention.
Detailed description of the invention:
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment:
As shown in Figure 1, parts like bent pipes processing positioning method of the present invention, comprises following sequential steps:
1) get bend pipe 1 clamping on bend pipe positioning tool 2, and make the flange face A3 of bend pipe 1 two-port and flange face B4 level outwardly, and flange face A3 keeps vertical with flange face B4 with horizontal plane;
2) with flange face A3 for benchmark, with probe detect and correct flange face A3 center reference aa;
3) theoretical flange face B4 center reference ba is conversed with the flange face A3 center reference after correction;
4) with the theoretical flange face B4 center reference ba conversed as benchmark, flange face B4 center reference bb is detected with probe, calculate the difference t=(bb-ba detecting flange face B4 center reference bb and theoretical flange face B4 center reference ba)/2, and the coordinate system that must make new advances, such as, probe data display flange face B4 center, lower than theoretical center value, will move down flange face B4 center the half of deviate;
5) go out the center reference ab of flange face A3 again with new coordinate system conversion, calculate the difference y detecting flange face A3 center reference aa and ab;
6) preset the overproof alarming value n of flange face A3, carry out overproof warning as y >=n, check bend pipe 1 and clamping, if bend pipe 1 is abnormal, reports abnormal and remove, if clamping is abnormal, after adjustment clamping, restart from step 1);
7) as y < n, then converse theoretical flange face B4 center reference ba ' according to the center reference ab of the flange face A3 conversed in step 5), calculate the difference x detecting flange face B4 center reference bb and ba ';
8) preset the overproof alarming value m of flange face B4, carry out overproof warning as x >=m, check bend pipe 1 and clamping, if bend pipe 1 is abnormal, reports abnormal and remove, if clamping is abnormal, after adjustment clamping, restart from step 1);
9) as x < m, it is qualified that bend pipe 1 is located.
Specific embodiment described herein is only to design of the present invention explanation for example.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
