Abstract

The present invention relates to a kind of zero-point positioning precision correcting methods of Five-axis NC Machining Center, by finding out off-limits coordinate value, subsequently into database, the statement of adjustment provided by equipment manufacturer, corresponding position coordinates are modified, so that final zero is followed and meets the requirements prescribed.The present invention can operate at any time at the scene, and automatic measurement system and standard ball are also general device, can be carried out at any time, therefore, there is at low cost, time-consuming short advantage, it by multiple practical operation, produces a desired effect, ensure that the normal use of Five-axis NC Machining Center.

Description

The zero-point positioning precision correcting method of Five-axis NC Machining Center
Technical field
The present invention relates to a kind of modification method, the zero-point positioning precision correcting method of especially a kind of Five-axis NC Machining Center.
Background technology
Five-axis NC Machining Center is a kind of consolidating processing equipment that precision is good, efficient in mechanical processing, is widely used in machine Tool manufacture field.Due to the movement of a variety of degree of freedom of Five-axis NC Machining Center work in-process, the synthesis that complex parts may be implemented adds Work, in process, the movement of main shaft or workbench, theoretical zero also move therewith, therefore it is that definition adds that zero, which follows, The leading indicator of work center precision is the basis for ensureing machining accuracy.When zero follows accuracy decline, need to repair it Just, the modification method of Five-axis NC Machining Center is completed by professional and professional equipment at present, and of high cost, efficiency bottom takes It is long.
Invention content
It is an object of the present invention to provide a kind of zero-point positioning precision correcting method of Five-axis NC Machining Center, this method has operation Simply, low, the efficient feature of maintenance cost.
The specific technical solution of the present invention is：
1) it chooses automatic measurement gauge head system and is mounted on the main shaft of lathe, by dedicated measurement tooling to gauge head school It tests and corrects automatically；
2) standard ball is mounted on the workbench of lathe；
3) start lathe, measure the centre of sphere of sphere, and the coordinate value of the centre of sphere is positioned to zero offset, that is, define the centre of sphere Coordinate be zero；
4) it rotates or vertical crouch overturns workbench, the ball position on workbench is made to change a certain distance；
5) start lathe, measure the sphere centre coordinate of the sphere after change in location, and record the Measured Coordinates value；
6) in the range of providing to allow, if the zero migration of lathe conforms to the deviation of Measured Coordinates value and zero It asks, use can be direct plungeed into；If the range that the deviation of Measured Coordinates value and zero allows beyond regulation carries out in next step Suddenly；
7) start lathe, off-limits index is searched according to lathe debugging specification book into the Universal Database of lathe The data subitem at place；
8) data subitem is changed, is preserved after all data beyond deviation index are added with former data；
9) restart lathe, repeat 3) -5) step；
10) in the range of providing to allow, if the zero migration of lathe meets the deviation of Measured Coordinates value and zero It is required that use can be direct plungeed into；If the deviation of Measured Coordinates value and zero beyond regulation allow range, comparison with it is upper One-shot measurement as a result, be modified compensation, until all indexs meet in the range of regulation allows.
The automatic measurement gauge head is Renishaw Probes system.
Described the 4) in step, and the distance of ball position variation is not less than the 1/5 of impulse stroke.
The present invention measures standard ball in mobile front and back sphere centre coordinate by automatic measurement system, and and zero It is compared with subsequent coordinate, finds out off-limits coordinate value, subsequently into database, the tune provided by equipment manufacturer Whole specification is modified corresponding position coordinates, and by multiple cycles such as revised re-test, amendment, makes most Whole zero, which follows, to meet the requirements prescribed, such as Receiving Inspection Instructions book set quota.The present invention can operate at any time at the scene, from Dynamic measuring system and standard ball are also general device, can be carried out at any time, therefore, have at low cost, take short advantage, It by multiple practical operation, produces a desired effect, ensure that the normal use of Five-axis NC Machining Center.
