Abstract
The invention discloses a kind of pinpoint method of frock, comprise the following steps: use software to find 2 holes in frock digital-to-analogue, then using the line in 2 holes and the center of circle in 2 holes as X-axis, set up coordinate system with the upper surface in the center of circle as Z axis；The frock of part puts into coordinate, and 2 holes in verification frock digital-to-analogue, using Reinshaw probe to look for 2 holes in frock respectively, to set up co-ordinate system location in the center of circle, round dot and digital-to-analogue consistent；The value that record is measured, then carries out calculating the deviant of actual frock, deviant is input in the rotary shaft of equipment；It is programmed checking, uses the coordinate system built up to look for other holes, make cutter just to pass in and out.The technical solution used in the present invention can efficiently solve the necessary vertical frock ground, hole of aerospace field frock location used, and the problem that round dot hole normal direction is vertical with upper surface so that drill tooling precise positioning cut by composite.
Description
Technical field
The invention belongs to aerospace field, cut, particularly to a kind of bigger multiple material, the side that drill tooling can be accurately positioned
Method.
Background technology
On the basis of the horizontal block cut on drill tooling in use one axially, dial gauge is used to come checking tool position
Degree.The tool locating precision less for some is no problem, but artificial very difficult movement heavier for frock volume ratio
Time the method the most limited, owing to part area is big so dimensional accuracy tolerance is the biggest.Along with change in design part is processed
Dimension precision requirement is harsh, causes the overproof problem of the tolerance of Dimension Measurement owing to tool locating exists trueness error, anxious
More preferable localization method need to be used to solve.
Chinese patent CN200910220632.8 discloses a kind of airplane complex construction member numerical control processing tool standard locator
Automatically selecting method, can define system and product joint location, determines candidate's localizer, preferred orientation device etc. by locator field by calculating
Process automatically determines the standard setting device type and spec meeting positioning requirements.The method can be applied to " aircraft complex structure
Part preparation system of quick numerical control machining " in " frock quickly generates subsystem " standard setting device automatically choose the exploitation of program.Carry
High Fixture Design efficiency, shorten frock development or even whole Operational preparation cycle, there is good application benefit.
Chinese patent CN201410040125.7 discloses the method that a kind of frock local increases hole, location.Utilize locating clip
Tool and the method for sunykatuib analysis on computers avoid frock and move local and bulk deformation after processing or accuracy
Defect.Install in conjunction with laser tracker, it is ensured that frock local increases the design drawing manufacture installation accuracy in hole, location and wants
Ask.
But necessary vertical frock ground, the hole of location used by the frock of existing use, and round dot hole normal direction is vertical with upper surface
Directly.
Summary of the invention
It is an object of the invention to for necessary vertical frock ground, the hole of location used by aerospace field frock, Yi Jiyuan
The problem that spot hole normal direction is vertical with upper surface, it is provided that a kind of pinpoint method of frock.
To achieve these goals, the present invention by the following technical solutions: a kind of pinpoint method of frock, including with
Lower step:
(1) software is used to find 2 holes in frock digital-to-analogue, then using the line in 2 holes and the center of circle in 2 holes as X-axis, with circle
The upper surface of the heart be Z axis set up coordinate system；
(2) frock of part is put into coordinate, 2 holes in verification frock digital-to-analogue, use Reinshaw to pop one's head in 2 in frock
Individual hole looks for that to set up co-ordinate system location in the center of circle, round dot and digital-to-analogue consistent respectively；
(3) record the value measured, then carry out calculating the deviant of actual frock, deviant is input to equipment
In rotary shaft；
(4) it is programmed checking, uses the coordinate system built up to look for other holes, make cutter just to pass in and out.
A diameter of 10mm in hole in described frock digital-to-analogue.
The technical solution used in the present invention can efficiently solve the hole of aerospace field frock location used and must hang down
Straight frock ground, and the problem that round dot hole normal direction is vertical with upper surface so that drill tooling precise positioning cut by composite.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
In frock digital-to-analogue, the hole of 2 Ф 10 is found first by software, then with 2 holes and the line in the center of circle in 2 holes
As X-axis, set up coordinate system with the upper surface in the center of circle as Z axis.(note: the upper surface in the center of circle is that plane is vertical with the normal direction in the center of circle
Directly) then the frock of part is put into Five Axis, 2 holes in verification frock digital-to-analogue, use Reinshaw to pop one's head in in frock
2 holes carry out looking for the center of circle respectively, round dot must be with to set up co-ordinate system location in digital-to-analogue the same.(note: probe finally detects round dot
Hole and the upper surface in round dot hole).And record the value measured, and then carry out calculating the deviant of actual frock, will partially
Shifting value is input in the rotary shaft of equipment.
Being programmed checking the most exactly, use the coordinate system built up to look for other holes, cutter can just pass in and out.Enter
Cross repeatedly experimental demonstration, find that the method can solve the problem that the problem that drill tooling precise positioning cut by composite.
The above, be only presently preferred embodiments of the present invention, and the present invention not does any type of restriction.Every
Any simple modification, equivalent variations and modification above example made according to technology and the method essence of the present invention, the most still
Belong in the range of technology and the method scheme of the present invention.
